RESUMEN / SUMMARY:  - OBJECTIVE: To study the effect of interleukin-2 receptor monoclonal antibodies on acute rejection episodes, graft loss, deaths, and rate of infection and malignancy in patients with renal transplants. DESIGN: Meta-analysis of published data. DATA SOURCES: Medline, Embase, and Cochrane library for years 1996-2003 plus search of medical editors’ trial amnesty and contact with manufacturers of the antibodies. SELECTION OF STUDIES: Randomised controlled trials comparing interleukin-2 receptor antibodies with placebo or no additional treatment in patients with renal transplants receiving ciclosporin based immunosuppression. RESULTS: Eight randomised controlled trials involving 1871 patients met the selection criteria (although only 1858 patients were analysed). Interleukin-2 receptor antibodies significantly reduced the risk of acute rejection (odds ratio 0.51, 95% confidence interval 0.42 to 0.63). There were no significant differences in the rate of graft loss (0.78, 0.58 to 1.04), mortality (0.75, 0.46 to 1.23), overall incidence of infections (0.97, 0.77 to 1.24), incidence of cytomegalovirus infections (0.81, 0.62 to 1.04), or risk of malignancies at one year (0.82, 0.39 to 1.70). The different antibodies had a similar sized effect on acute rejection (test for heterogeneity P=0.7): anti-Tac (0.37, 0.16 to 0.89), BT563 (0.37, 0.1 to 1.38), basiliximab (0.56, 0.44 to 0.72), and daclizumab (0.46, 0.32 to 0.67). The reduction in acute rejections was similar for all ciclosporin based immunosuppression regimens (test for heterogeneity P=1.0). CONCLUSIONS: Adding interleukin-2 receptor antibodies to ciclosporin based immunosuppression reduces episodes of acute rejection at six months by 49%. There is no evidence of an increased risk of infective complications. Longer follow up studies are needed to confirm whether interleukin-2 receptor antibodies improve long term graft and patient survival.

RESUMEN / SUMMARY:  - BACKGROUND: In an attempt to reduce chronic calcineurin inhibitor induced allograft nephropathy in first cadaver and human leukocyte antigen non-identical living-donor renal transplantation, sirolimus (Siro) or mycophenolate mofetil (MMF) was tested as adjunctive therapy, with planned dose reductions of tacrolimus (Tacro) over the first year postoperatively. Adjunctive Siro therapy with a similar dose reduction algorithm for Neoral (Neo) was included for comparison. METHODS: The detailed dose reduction plan (Tacro and Siro, group A; Tacro and MMF, group B; Neo and Siro, group C) is described in our companion report in this issue of Transplantation. The present report documents function, patient and graft survival, protocol compliance, and adverse events. RESULTS: As mentioned (in companion report), group demographics were similar. The present study shows no significant differences in 1-year patient and graft survival but does show a trend that points to more difficulties in group C by way of a rising slope of serum creatinine concentration (P=0.02) and decreasing creatinine clearance (P=0.04). There were more patients who discontinued the protocol plan in group C. Thus far, no posttransplant lymphomas have appeared, and infectious complications have not differed among the groups. However, a greater percentage of patients in group C were placed on antihyperlipidemia therapy, with an (unexpected) trend toward a higher incidence of posttransplant diabetes mellitus in this group. Group A required fewer, and group B the fewest, antihyperlipidemia therapeutic interventions (P<0.00001). CONCLUSIONS: This 1-year interim analysis of a long-term, prospective, randomized renal-transplant study indicates that decreasing maintenance dosage of Tacro with adjunctive Siro or MMF appears to point to improved long-term function, with reasonably few adverse events.

RESUMEN / SUMMARY:  - PURPOSE: Optimal management and clinical outcome of bladder cancer in renal transplant recipients are not well-defined. We analyzed single institution treatment strategies and outcomes of these patients. MATERIALS AND METHODS: We retrospectively reviewed the University of California, San Francisco transplant database which contains information on 6,288 renal transplants performed between 1964 and 2002. The United Network for Organ Sharing database and Israel Penn International Transplant Tumor Registry were also queried to characterize the global nature of bladder cancer in renal transplant recipients. RESULTS: The United Network for Organ Sharing database (1986 to 2001) contained information on 31 patients who were found to have bladder cancer (0.024% prevalence) and the Israel Penn International Transplant Tumor Registry (1967 to 2001) contained information on 135 patients representing 0.84% of all reported malignancies. We identified 7 renal transplant recipients with bladder cancer at our institution. Invasive transitional cell carcinoma developed in 5 patients at a median of 2.8 years after transplant. Three patients underwent uncomplicated radical cystectomy and preservation of the renal allograft. Overall survival at 48 months was 60%. CONCLUSIONS: Bladder cancer after renal transplantation is not common. For patients who present with invasive disease, traditional extirpative surgery should be considered. Moreover, the allograft is rarely the source of transitional cell carcinoma and can be preserved. In our experience the cancer and urinary outcomes compare favorably with nontransplant patient outcomes after treatment.  N. Ref:: 21

RESUMEN / SUMMARY:  - BACKGROUND: Hemophagocytic syndrome (HPS) combines febrile hepatosplenomegaly, pancytopenia, hypofibrinemia, and liver dysfunction. It is defined by bone marrow and organ infiltration by activated, nonmalignant macrophages phagocytizing blood cells. HPS is often caused by an infectious or neoplastic disease and has rarely been described in renal transplant recipients. METHODS: We retrospectively analyzed 17 cases of HPS after cadaveric renal transplantation (13 men and 4 women, age 41+/-8 years). The median time between transplantation and hemophagocytosis was 52 days. Eleven patients (64%) had received antilymphocyte globulins during the 3 months before presentation. RESULTS: Fever was present in all patients, and hepatosplenomegaly was present in 9 of 17 patients. Other nonspecific clinical findings included abdominal, neurologic, and respiratory symptoms. Laboratory tests showed anemia (hemoglobin 6.1+/-1.3 g/dL), thrombocytopenia (34,000+/-32,000/mm3), and leukopenia (1,700+/-1,400/mm3). Elevated liver enzymes were present in 12 of 17 patients, and cholestasis was present in 10 of 17 patients. Elevated triglycerides and ferritin were noted in 75% and 86% of cases, respectively. HPS was related to viral infection in nine patients (cytomegalovirus, Epstein-Barr virus, human herpesvirus 6, and human herpesvirus 8), bacterial infection in three patients (tuberculosis and Bartonella henselae), and other infections in two patients (toxoplasmosis and Pneumocystis carinii pneumoniae). Posttransplant lymphoproliferative disease was present in two patients. Despite large-spectrum anti-infectious treatment and dramatic tapering of immunosuppression, death occurred in eight patients (47%). Graft nephrectomy was performed in four of the nine surviving patients. CONCLUSIONS: We report here the largest series of HPS after renal transplantation. This rare disease is usually secondary to herpes viridae infections, mostly cytomegalovirus and Epstein-Barr virus in severely immunocompromised patients. Despite aggressive treatment, the prognosis remains poor.  N. Ref:: 22

RESUMEN / SUMMARY:  - GUIDELINES: A. In the first year after organ transplantation, recipients are at the greatest risk of developing lymphoproliferative diseases (PTLDs), which are induced most often by Epstein-Barr virus (EBV) infection, and patients should therefore be screened prior to or at the time of transplantation for EBV antibodies. B. In the rare cases (<5%) where the recipient is EBV seronegative, he or she has a 95% likelihood of receiving an organ from an EBV-seropositive donor, which translates into a high risk of primary EBV infection with seroconversion soon after transplantation. In such cases, the recipient should receive a prophylactic antiviral treatment with acyclovir, valacyclovir or ganciclovir, starting at the time of transplant and lasting for at least 3 months. The specific recommendations given for CMV prophylaxis could be applicable in this situation. C. The treatment of PTLD should be based on accurate pathology with extensive cell markers and phenotyping. The treatment modalities are as follows. Reduction of basal immunosuppression in all cases (either maintain only steroids, or decrease by at least 50% the anti-calcineurin drugs and stop other immunosuppressive drugs). In the case of EBV-positive B-cell lymphoma, antiviral treatment with acyclovir, valacyclovir or ganciclovir may be initiated for at least 1 month or according to the blood level of EBV replication when available. In the case of rare lymphomas from the mucosal-associated lymphoid tissue (MALT) with positive Helicobacter pylori, full eradication of H. pylori should be carried out with a validated protocol. Subsequent H. pylori prophylaxis should be implemented to avoid relapse. In the case of CD20-positive lymphomas, treatment with rituximab, a chimeric monoclonal antibody directed against CD20, should be carried out with one i.v. injection per week for 4 weeks. In the case of diffuse lymphomas or improper response to previous treatment, CHOP chemotherapy should be used alone or in combination with rituximab. The CHOP regimen is cyclophosphamide, doxorubicine, vincristine and prednisone. Complete cessation of immunosuppression with or without graft nephrectomy should also be considered.

RESUMEN / SUMMARY:  - Dialysis patients constitute a high-risk subset of patients for developing cardiovascular disease, which accounts for nearly 50% of deaths. After stratification for age, race and gender, cardiovascular mortality is 10-20 times higher in dialysis patients than in the general population. Cardiovascular disease in this population cannot be fully explained by the high prevalence of classical cardiovascular risk factors (age, hypertension, diabetes, hyperlipidemia, smoking, etc.). Thus, the involvement of “new” cardiovascular risk factors (hyperhomocysteinemia, hyperfibrinogenemia, high lipoprotein (a) levels, oxidative stress, inflammation, etc.), and uremia-related factors (anemia, impaired calcium-phosphorus metabolism, hyperparathyroidism, accumulation of endogenous inhibitors of nitric oxide synthesis, etc.) has been also invoked to play a role in the increased cardiovascular risk in these patients. Endothelial dysfunction is the initial event in the development of atherosclerosis. Uremic patients exhibit an endothelial dysfunction, even before starting dialysis, which persists o is even aggravated under dialysis treatment. Uremic patients must be considered at high risk of developing cardiovascular disease. Thus cardiovascular risk factors in these patients should be managed early, aggressive and multifactorially in order to reduce their high cardiovascular morbidity and mortality.  N. Ref:: 52

RESUMEN / SUMMARY:  - How to combine antirejection drugs and which is the optimal dose of steroids and calcineurin inhibitors beyond the first year after kidney transplantation to maintain adequate immunosuppression without major side effects are far from clear. Kidney transplant patients on steroid, cyclosporine (CsA), and azathioprine were randomized to per-protocol biopsy (n = 30) or no-biopsy (n = 29) 1 to 2 yr posttransplant. Steroid or CsA were discontinued or reduced on the basis of biopsy to establish effects on drug-related complications, acute rejection, and graft function over 3 yr of follow-up. Serum creatinine, GFR (plasma clearance of iohexol), RPF (renal clearance of p-aminohippurate), CsA pharmacokinetics, and adverse events were monitored yearly. At the end, patients underwent a second biopsy. Per-protocol biopsy histology revealed no lesions (n = 5, steroid withdrawal), CsA nephropathy (n = 13, CsA discontinuation/reduction), or chronic rejection (n = 12, standard therapy). Reducing the drug regimen led to overall fewer side effects related to immunosuppression as compared with standard therapy or no-biopsy. Steroids were safely stopped with no acute rejection or graft loss. Complete CsA discontinuation was associated with acute rejection in the first four patients. Lowering CsA to low target CsA trough (30 to 70 ng/ml) never led to acute rejection or major renal function deterioration. Biopsy patients on conventional regimen had no acute rejection, one graft loss, no significant change in GFR, and significant RPF decline. No-biopsy controls: no acute rejection, one graft loss, significant decline of GFR and RPF. By serial biopsy analysis, severe lesions did not develop in patients with steroid discontinuation in contrast to patients on standard therapy over follow-up. CsA reduction did not adversely affect histology. Per-protocol biopsy more than 1 yr after kidney transplantation is a safe procedure to guide change of drug regimen and to lower the risk of major side effects.

RESUMEN / SUMMARY:  - GUIDELINES: J. All renal transplant recipients should have regular ultrasonography of their native kidneys (when applicable) for screening of renal cell carcinomas, which are observed at much higher incidence in both dialysed and transplant patients. K. Guidelines published for screening and prevention of solid organ cancers in the general population should be strictly applied to transplant recipients, who are in general at higher cancer risk, but would benefit equally or even greater. L. All male renal transplant recipients aged 50 and over should have a yearly prostate specific antigen (PSA) test prior to a regular digital rectal examination. M. All female renal transplant recipients should have a yearly cervical (PAP) smear together with regular pelvic examination and regular mammography, according to national recommendations where available. N. All renal transplant recipients should undergo a faecal occult-blood testing as a screening for colorectal cancer and other (pre-malignant) lesions, according to national recommendations where available. O. In all these conditions, it is recommended to reduce immunosuppression whenever possible.

RESUMEN / SUMMARY:  - GUIDELINES: A. Post-transplant cardiovascular disease is very common, an important cause of morbidity and the first cause of mortality in renal transplant recipients. Therefore, detection and early treatment of post-transplant cardiovascular disease are mandatory. B. Specific risk factors for developing post-transplant cardiovascular disease include pre-transplant cardiovascular disease, arterial hypertension, uraemia (graft dysfunction), hyperlipidaemia, diabetes mellitus, smoking and immunosuppressive treatment. These factors should be targeted for intervention. C. Pre-transplant cardiovascular disease is a major risk factor for post-transplant cardiovascular disease. Therefore, prior to transplantation, it is mandatory to detect and treat symptomatic coronary artery disease, heart failure due to valvular failure or cardiomyopathy, and pericardial constriction. This policy should also be followed in asymptomatic diabetic patients.

RESUMEN / SUMMARY:  - GUIDELINES: D. Due to the high prevalence of skin cancers after organ transplantation, it is highly recommended to inform patients about self-awareness. E. Primary prevention should include the avoidance of sun exposure, use of protective clothing and use of an effective sunscreen (protection factor >15) for unclothed body parts (head, neck, hands and arms) in order to prevent the occurrence of squamous-cell carcinoma. This is the most frequent skin tumour in transplant recipients, and its preferential location is the head. F. Recipients with pre-malignant skin lesions (warts, epidermodysplasia verruciformis or actinic keratoses) should be referred early to a dermatologist for active treatment and close follow-up. G. All skin cancers should be completely removed by a dermatologist with appropriate techniques, such as electro-desiccation with curettage, cryotherapy or surgical excision. H. Secondary prevention for recipients should include close follow-up by a dermatologist (at least every 6 months), the use of topical retinoids to control actinic keratoses and to diminish squamous-cell carcinoma recurrence, and reduction of immunosuppression whenever possible. I. In recipients with multiple and/or recurrent skin cancers, the use of systemic retinoids, such as low-dose acitretin, could be recommended for months/years, if well tolerated, in addition to further reduction in immunosuppression whenever possible.

RESUMEN / SUMMARY:  - A renal transplant recipient with 13 years of excellent allograft function was found incidentally to have a malignant mass in his transplanted kidney. After resection, pathological analysis showed 29 separate lesions of renal cell carcinoma. All tumors were confined within the renal capsule. The majority of tumors (21 of 29 tumors) were chromophil basophilic carcinoma with papillary architecture, 5 tumors were clear cell, 2 tumors were mixed cell type, and 1 tumor was chromophil eosinophilic papillary carcinoma. These histological findings are similar to those reported in hereditary papillary renal carcinoma. To our knowledge, this is the first case of multicentric papillary renal carcinoma occurring in the renal allograft. We speculate that the allograft in this case is predisposed to malignant changes because of preexisting genetic mutations, as well as prolonged immunosuppression.  N. Ref:: 13

RESUMEN / SUMMARY:  - We describe three cases of subcutaneous phaeohyphomycosis developing in the lower limbs of renal transplant recipients shortly after transplantation. Each case presented with dark-colored nodules that subsequently ulcerated. Histopathologic examination revealed dematiaceous fungal hyphae with a surrounding granulomatous reaction. The fungi were subsequently identified as Alternaria alternatum in two cases and Phialophora richardsiae in one case. In one case, the lesions resolved during a prolonged (6-month) course of itraconazole without the requirement for surgical excision. In the other two cases, combined medical and surgical treatment resulted in cure. A review of the literature on phaeohyphomycosis is presented.  N. Ref:: 11

RESUMEN / SUMMARY:  - This study is an investigation of whether a protocol biopsy may be used as surrogate to late graft survival in multicenter renal transplantation trials. During two mycophenolate mofetil trials, 621 representative protocol biopsies were obtained at baseline, 1 yr, and 3 yr. The samples were coded and evaluated blindly by two pathologists, and Chronic Allograft Damage Index (CADI) score was constructed. At 1 yr, only 20% of patients had elevated (>l.5 mg/100 ml) serum creatinine, whereas 60% of the biopsies demonstrated an elevated (>2.0) CADI score. The mean CADI score at baseline, 1.3 +/- 1.1, increased to 3.3 +/- 1.8 at 1 yr and to 4.1 +/- 2.2 at 3 yr. The patients at 1 yr were divided into three groups, those with CADI <2, between 2 and 3.9, and >4.0, the first two groups having normal (1.4 +/- 0.3 and 1.5 +/- 0.6 mg/dl) and the third group pathologic (1.9 +/- 0.8 mg/dl) serum creatinine. At 3 yr, there were no lost grafts in the low CADI group, six lost grafts (4.6%) in the in the elevated CADI group, and 17 lost grafts (16.7%) in the high CADI group (P < 0.001). One-year histologic CADI score predicts graft survival even when the graft function is still normal. This observation makes it possible to use CADI as a surrogate end point in prevention trials and to identify the patients at risk for intervention trials.

RESUMEN / SUMMARY:  - GUIDELINES: A. Acute pyelonephritis is relatively frequent in the transplanted kidney and carries a risk of septicaemia. The condition should be recognized and the patient should be treated promptly in the hospital. B. After initiation of any drugs known to induce the development of interstitial nephritis in the transplant patient, it is recommended to monitor renal function and abnormalities in order to detect any side effects rapidly. If interstitial nephritis is observed, it is recommended to stop the offending drug, and to initiate appropriate treatment. C. De novo membranous nephropathy should be considered in cases of proteinuria and nephrotic syndrome after transplantation. Viral infection, such as HCV, should be excluded. D. In the case of the development of graft dysfunction in a transplant patient with Alport’s syndrome, one should consider additionally the possibility of de novo anti-glomerular basement membrane (anti-GBM) glomerulonephritis.

RESUMEN / SUMMARY:  - Cytomegalovirus (CMV) infection and disease, with its extensive direct and indirect consequences, adds considerably to the cost of patient management in both solid organ and bone marrow transplantation. Antiviral prophylaxis for CMV infection can offer cost advantages over preemptive therapy and “wait-and-treat” approaches. Valacyclovir has demonstrated efficacy for CMV prophylaxis in renal, heart, and bone marrow transplantation and is cost-effective when compared with placebo in renal transplant recipients at high risk of CMV infection. In reducing CMV infection and disease, valacyclovir prophylaxis appears to be associated with reductions in indirect effects of CMV (acute graft rejection, other opportunistic infections) and, if these effects are considered, the potential exists for even greater savings to be made with valacyclovir therapy. Benefits of valacyclovir in transplantation extend beyond CMV to other herpesviruses and may be increased in some clinical situations by prolonging prophylaxis beyond 3 months.  N. Ref:: 32

RESUMEN / SUMMARY:  - GUIDELINES: A. It is important for a transplant unit to follow-up on the results of their transplant activities. In order to achieve correct reports on graft and patient outcome in all patients, it is necessary to have sufficient resources, such as a computerized database, and continuous updates of patient information. All data collected should be subjected to validation procedures to ensure completeness and accuracy. B. Improved outcomes following implementation of new protocols, based on evaluation of clinical multi-centre trials, should be verified at local transplant centres since centres often include a range of patients different from those selected for the trial. C. The most widely accepted descriptor of outcome is the Kaplan-Meier probability estimate of patient and graft survival. Survival estimates should be calculated at intervals of time after transplantation and should always be expressed with their 95% confidence intervals. D. Kaplan-Meier survival estimates may be calculated in three ways. (i) ‘Patient survival’ should be calculated from the date of transplantation to the date of death or the date of the last follow-up. (ii) ‘Graft survival’ (non-censored for death) should be calculated from the date of transplantation to the date of irreversible graft failure signified by return to long-term dialysis (or retransplantation) or the date of the last follow-up during the period when the transplant was still functioning or to the date of death. Here, death with graft function is treated as graft failure. (iii) ‘Graft survival censored for death with a functioning graft’ (death-censored graft survival) should be calculated from the date of transplantation to the date of irreversible graft failure signified by return to long-term dialysis (or retransplantation) or the date of last follow-up during the period when the transplant was still functioning. In the event of death with a functioning graft, the follow-up period is censored at the date of death. E. The outcome of transplants carried out at a centre should be compared with those achieved across a range of data from centres collated by national and international multi-centre registries. Interpretation of a centre’s performance should take into account the number of transplants performed and the prevalence of major risk factors. F. Major risk factors that influence transplant outcome are identifiable by applying multivariate analytical methods to large multi-centre follow-up databases. Although these major risk factors may not be identifiable in individual centre data, they should nonetheless be taken into account in patient management. G. When designing a clinical trial or evaluating data from a recent trial, the expected improvement in graft survival resulting from a reduction in acute rejection may be estimated from a knowledge of the rejection and graft survival rates that existed prior to the introduction of the new therapeutic regimen. H. When designing or evaluating a clinical trial, it is important to analyse the power of the study to verify statistically the difference (in graft survival) that might be expected and its statistical significance. A study resulting in absence of statistically significant differences between two treatment groups with insufficient statistical power to verify a difference at the expected level should not be taken as evidence of absence of a true difference.

RESUMEN / SUMMARY:  - Acute rejection is a major risk factor for kidney graft failure. However, as acute rejection has been progressively reduced by recent immunosuppressive regimens, other risk factors are becoming increasingly important. Evidence is accumulating that early renal function predicts long-term outcome. A recent registry survey of more than 100 000 kidney transplants found that 6- and 12-month serum creatinine levels, as well as the change between 6 and 12 months, are strongly associated with long-term graft survival. A survey of paediatric renal transplant recipients showed that poor creatinine clearance (<50 ml/min) as early as 30 days post-transplant predicted an annual rate of graft loss of 13% compared with <3% in patients with 30-day clearance >50 ml/min. This association between early renal function and long-term outcome was confirmed in multicentre studies. Renal transplant recipients (n=572) with 6-month serum creatinine levels >1.5 mg/dl suffered 3-year graft loss of 19.3% compared with only 8.5% in patients with levels <1.6 mg/dl (P<0.001). Significantly fewer patients receiving tacrolimus had 12-month serum creatinine levels >1.5 mg/dl compared with cyclosporin (42 versus 54%, P<0.05). Interestingly, a single-centre study (n=436) found that while glomerular filtration rate (GFR) at 6 months post-transplant had remained stable over the last decade, the rate of loss of renal function had decreased. A lower rate of GFR loss was associated with absence of rejection, use of mycophenolate mofetil rather than azathioprine and use of tacrolimus rather than cyclosporin (P<0.01). In conclusion, early measures of renal function allow identification of those patients at highest risk of graft failure and provide an invaluable tool for improving outcomes by tailored immunosuppression. The choice of such immunosuppression should be guided not only by its ability to prevent rejection, but also by its impact on renal function.  N. Ref:: 11

RESUMEN / SUMMARY:  - BACKGROUND: Pseudomonas aeruginosa is an uncommon cause of infection in the female genital tract. We report a case of postmenopausal tubo-ovarian abscess (TOA) due to P. aeruginosa in a renal transplant recipient. The presentation included mild abdominal symptoms with rapid progression of peritonitis and surgical abscess drainage. This is the first such case in an organ transplant recipient described in the English literature. METHODS AND RESULTS: Published reports of 1040 cases of TOA were reviewed. The most common features were a history of sexually transmitted disease or pelvic inflammatory disease, and symptoms including abdominal pain and fever. Escherichia coli, Bacteroides spp., and Klebsiella pneumoniae were the most frequently encountered pathogens. Neisseria gonorrhoeae and Chlamydia trachomatis, which are frequently isolated from cervical cultures, are uncommonly isolated from tubo-ovarian abscesses. Forty percent of patients were treated with antibiotics alone, 18.8% with abdominal surgery, and 32% with surgery and antimicrobial therapy. CONCLUSION: This report illustrates the muted presentation and atypical microbiology of gynecologic infection in an organ transplant recipient.  N. Ref:: 59

RESUMEN / SUMMARY:  - GUIDELINE: Immunosuppressive therapies, especially corticosteroids and anticalcineurin inhibitors; contribute to the prevalence of cardiovascular risk factors, such as arterial hypertension, hyperlipidaemia and hyperglycaemia, and this effect is dose dependent. Reduction of the dose, withdrawal and/or switching to another drug could be useful to control these risk factors.

RESUMEN / SUMMARY:  - GUIDELINES: A. In the rare case of recurrent lupus nephritis, no particular treatment is recommended. Only in the few patients with clinically evident flare up is a reinforcement of immunosuppression recommended. B. Recurrence of Henoch-Schonlein purpura may occur even in the absence of clinical signs and symptoms. The prognosis for the graft may be severe, particularly in adults. C. In the case of recurrent ANCA-associated renal or systemic vasculitis, it is recommended to reinforce the immunosuppression with appropriate agents. D. Since diabetic nephropathy recurs almost invariably after transplantation, strict control of diabetes and hypertension, and the use of ACE inhibitors and/or angiotensin II receptor antagonists are recommended in order to prevent or slow the risk of recurrence.

RESUMEN / SUMMARY:  - Lymphoma involving the prostate is rare, both as a primary and as a secondary presenting. Usually the prognosis remains poor. The clinical presentation is similar to that of other lower urinary tract obstructions, in fact prostatic lymphoma must be considered in patients with these symptoms, particularly in patients with prior history of systemic lymphoma. We report a case of a kidney transplantation in a male patient, diagnosis of lymphoma non Hodgkin, with later recurrence in prostate.  N. Ref:: 6

RESUMEN / SUMMARY:  - Bone disease is common after renal transplantation. The main syndromes are bone loss with a consequent fracture rate of 3% per year, osteonecrosis of the hip, and bone pain. The causes of disease include preexisting uremic osteodystrophy (hyperparathyroidism, aluminum osteomalacia, beta2-associated amyloidosis, and diabetic osteopathy), postoperative glucocorticoid therapy, poor renal function, and ongoing hyperparathyroidism, as the result of either autonomous transformation of the parathyroid gland or ongoing physiologic stimuli. Cyclosporine A treatment, hyperphosphaturia, and a pathogenic vitamin D allele have also been implicated. Bone loss is particularly pronounced during the first year after operation, amounting to up to 9% of bone mass. The clinical and biochemical picture is consistent with a high turnover bone disease, but histomorphometric studies do not completely support this. Principal prophylactic options include preoperative osteodystrophy prophylaxis; postoperative calcium, vitamin D, or calcitriol therapy; estrogen therapy for postmenopausal women; and parathyroidectomy for medically intractable hyperparathyroidism. Recently, prophylactic biphosphonate treatment has shown promise, but the exact indications for treatment remain to be determined.  N. Ref:: 221

RESUMEN / SUMMARY:  - GUIDELINES: A. All kidney-transplanted patients should undergo a systematic evaluation of their skeletal status, including pre-transplant history of renal osteodystrophy, history of fractures and plasma concentrations of calciotropic hormones and other parameters, and if possible measurement of bone mineral density (BMD). B. Glucocorticoid therapy should be given at the lowest possible dosage. As long as patients are receiving steroids, vitamin D treatment (ergocalciferol or 1,25-dihydroxyvitamin D) is highly recommended. C. Optimal prevention of bone disease by vitamin D treatment, sufficient calcium intake, sex hormone substitution and appropriate use of thiazide diuretics should be considered in all transplant patients. D. In established osteopenia, bisphosphonate treatment should be considered despite limited information in transplant recipients. E. Persistent tertiary hyperparathyroidism should be observed for 1 year after transplantation whenever possible to allow for a spontaneous involution. F. In patients with GFR <50 ml/min after transplantation, uraemic osteodystrophy should be prevented.

RESUMEN / SUMMARY:  - Interleukin-2 (IL-2) and its receptor (IL-2R) play a central role in T lymphocyte activation and immune response after transplantation. Research on the biology of IL-2R allowed the identification of key signal transduction pathways involved in the generation of proliferative and antiapoptotic signals in T cells. The alpha-chain of the IL-2R is a specific peptide against which monoclonal antibodies have been raised, with the aim of blunting the immune response by means of inhibiting proliferation and inducing apoptosis in primed lymphocytes. Indeed, basiliximab, one of such antibodies, has proved to be effective in reducing the episodes of acute rejection after kidney and pancreas transplantation. The use of basiliximab was associated with a significant reduction in the incidence of any treated rejection episodes after kidney transplantation in the two major randomised studies (placebo 52.2% vs basiliximab 34.2% at 6 months, European study; placebo 54.9% vs basiliximab 37.6% at 1 year, US trial). Basiliximab and equine antithymocyte globulin (ATG) administration resulted in a similar rate of biopsy-proven acute rejection at 6 months (19% for both) and at 12 months (19% and 20%, respectively). The use of basiliximab appears not to be associated with an increased incidence of adverse events as compared with placebo in immunosuppressive regimens, including calcineurin inhibitors, mycophenolate mofetil or azathioprine and corticosteroids, and its safety profile is superior to ATG. Moreover, a similar occurrence of infections is noted in selected studies (65.5% after basiliximab vs 65.7% of controls), including cytomegalovirus infection (17.3% vs 14.5%), and cytokine-release syndrome is not observed. Finally, economic analysis demonstrated lower costs of overall treatment in patients treated with basiliximab. Therefore, the use of basiliximab entails a very low risk, allows safe reduction of corticosteroid dosage and reduces the short- and mid-term rejection rates. However, the improvement in the long-term survival of kidney grafts in patients treated according to modern immunosuppressive protocols is still to be demonstrated. These conclusions are based on a systematic review of the scientific literature, indexed on Medline database, concerning the mechanism of action, therapeutic activity, safety and pharmacoeconomic evaluation of basiliximab in renal transplantation.  N.

RESUMEN / SUMMARY:  - GUIDELINES: A. Approximately 5% of patients develop Pneumocystis carinii pneumonia (PCP) after renal transplantation if they do not receive prophylaxis. PCP is a severe disease, with a very high fatality rate. Therefore, all renal transplant recipients should receive PCP prophylaxis. The treatment of choice is trimethoprim-sulfamethoxazole (TMP-SMX), at a dose of 80/400 mg/day or 160/800 mg every other day, for at least 4 months. Patients who are treated for rejection should receive TMP-SMX prophylaxis for 3-4 months. B. In the case of TMP-SMX intolerance, aerosolized pentamidine (300 mg once or twice per month) is an alternative for prophylaxis. C. The first-line treatment of PCP is high-dose TMP-SMX. Patients with a PaO2 of <70 mmHg initially should be treated parenterally, and the administration of additional steroids should be considered.

RESUMEN / SUMMARY:  - OBJECTIVES: Aneurysmatic processes of the renal artery after transplant are rare entities, generally secondary to technical defects or infectious pictures. Among other presentations, dissecting aneurysm are exceptional, having a particularly difficult diagnosis due to the lack of specific clinical data which could differentiate them from other processes such as graft rejection or acute tubular necrosis, as well as the absence of characteristic representative images. METHODS: We report one case of dissecting aneurysm after a kidney transplant resulting in graft loss. RESULTS: We analyze the presentation form, diagnostic procedures, pathologic studies, and possible therapeutic options. CONCLUSIONS: Dissecting aneurysm of the renal artery is a rare entity of difficult diagnosis due to the poorness of presenting symptoms and the difficulty of finding it in routine tests, being necessary to think of it and to perform angiography as the only diagnostic test. Treatment is carried out by hilar reconstruction or transplant nephrectomy when the former is not possible.  N. Ref:: 10

RESUMEN / SUMMARY:  - Nephrotic syndrome (NS) is frequent in renal transplant recipients and may be related to a large variety of glomerular lesions. In some of these cases, the transplant biopsy showed no significant glomerular changes and the NS was reversible, but the primary renal disease was not minimal change disease (MCD), suggesting that MCD may develop de novo in renal transplant setting. Knowledge of this entity, however, is limited. Among 67 cases of post-transplant NS encountered in a 12-yr period, five were found to be associated with de novo MCD. A critical review of the literature revealed nine additional cases of de novo MCD. The data from these 14 cases show that patients with de novo MCD had a large variety of primary renal diseases but MCD or focal segmental glomerulosclerosis was not among them. Eight of the 14 transplanted kidneys (60%) were from living related donors, suggesting this as a risk factor. Nephrotic range proteinuria (3-76 g/d) developed immediately or shortly after transplantation (within 4 months for all reported cases, except for one at 24 months). The serum creatinine when NS was first diagnosed was normal or mildly elevated, but acute renal failure occurred in three patients. On biopsy, the glomeruli were normal or, more frequently, displayed mild, focal segmental mesangial sclerosis, hypercellularity, deposition of IgM/C3, or accumulation of mononuclear inflammatory cells in some glomerular capillaries. The tubulointerstitial compartment was normal in cases with normal renal function; displayed mild acute and/or chronic rejection that correlated with a mildly elevated serum creatinine; or showed acute changes including acute rejection, acute tubular necrosis, or acute cyclosporin A toxicity, which accounted for both acute renal failure at presentation and its subsequent reversibility. Under various treatments, including increased steroids, angiotensin converting enzyme inhibitors, calcium channel blockers and angiotensin receptor blockers, sustained remission of NS was achieved in 13 cases, within a year (0.5-12 months) in 10 and later (24, 34 and 98 months, respectively) in three. In the remaining case, the patient died of septic shock 2 months after transplantation. After remission of the NS, the grafts functioned well without or with minimal proteinuria for several years. De novo MCD has characteristic clinical and pathologic features. It represents an important but hitherto underemphasized cause of post-transplant NS, which is potentially reversible and does not adversely affect the renal transplants.  N. Ref:: 37

INSTITUCIÓN / INSTITUTION:  - Transplant Unit, The Royal Infirmary of Edinburgh, UK. john.forsythe@luht.scot.nhs.uk

RESUMEN / SUMMARY:  - The high incidence of cardiovascular disease after renal transplantation is related to a high prevalence and accumulation of risk factors before and after transplantation. Hypertension, posttransplantation diabetes, and hyperlipidemia are well-recognized risk factors for the development of cardiovascular events after renal transplantation and are strongly associated with immunosuppressive therapy. Hyperhomocysteinemia is a potential risk factor for cardiovascular disease in renal transplant recipients, but although a growing matter of study, a direct association with immunosuppressive agents is not yet proven. In addition to treatment intervention, risk management should also involve tailoring the immunosuppressive regimen to minimize the more indirect cardiovascular risk factors such as renal dysfunction and acute rejection.  N.

RESUMEN / SUMMARY:  - GUIDELINES: A. Arterial hypertension is often present after renal transplantation and is of multifactorial origin. Pre-transplant arterial hypertension, chronic allograft nephropathy and immunosuppressive therapy are the most frequent causes of post-transplant arterial hypertension. Careful monitoring and treatment of high blood pressure are recommended following transplantation. B. Post-transplant arterial hypertension is associated with an increased incidence of cardiovascular disease in renal transplant patients and is an independent risk factor for graft failure. Therefore, blood pressure control (<130/85 mmHg for renal transplant recipients without proteinuria, and <125/75 mmHg for proteinuric patients) is mandatory in these patients. General measures and pharmacological intervention are necessary in many cases. In proteinuric patients, anti-hypertensive and anti-proteinuric agents could be used, and stricter blood pressure control is recommended. C. In patients with uncontrolled arterial hypertension and/or renal function deterioration, underlying causes should be excluded, especially transplant renal artery stenosis.

TÍTULO / TITLE:  - Fragility fractures in dialysis and transplant patients. Is it osteoporosis, and how should it be treated?

AUTORES / AUTHORS:  - Hodsman AB

RESUMEN / SUMMARY:  - The term “osteoporosis” must be applied with caution to the uremic population, which has a complex range of metabolic bone disease. Trials of therapeutic interventions to prevent fractures in non uremic populations with osteoporosis cannot be generalized to uremic patients. It is unclear what, if any, role systematic bone densitometry measurement can play in the management of uremic patients who suffer “fragility” fractures—either for diagnostic purposes or to determine the effectiveness of therapy. Estrogen therapy—and perhaps SERMs (raloxifene)--appear to be a reasonable addition to conventional management of secondary HPT with calcium salts and vitamin D analogs. Using bisphosphonates to manage patients who have pre-existing fractures should be considered experimental at best. In certain circumstances, such treatment may be harmful. While the evidence is better that early therapy with intravenous pamidronate in the peri-transplant interval may mitigate the steroid-induced bone loss seen in those patients during the first 12 postoperative months, even that indication needs to be subjected to systematic clinical studies to develop appropriate clinical practice guidelines.  N.

RESUMEN / SUMMARY:  - Twenty-year protocol biopsies were performed in four cases of renal transplant recipients with grafts that had survived 20 years or more. All four recipients received transplants from their parents, and never had episodes of acute rejection. They were maintained with the conventional immunosuppressive protocol including azathioprine, mizoribine, and prednisolone. Three of them had past history of malignant diseases such as breast cancer and tongue cancer. In spite of fair graft function, the microscopic findings of 20-year protocol biopsy showed various degrees of histological damage; e.g. obsolescence of the glomeruli, glomerulosclerosis, arteriole wall thickening, interstitial fibrosis and tubular atrophy. Although two of the four grafts were functioning with low serum creatinine levels (1.3-1.4 mg dL-1) at 24 years and 26 years following transplantation, respectively, the function of the other two grafts had decreased more than 20 years after transplantation. In the two grafts with decreased function, glomerulosclerosis and arteriole wall thickening tended to be more severe (Banff classification of chronic allograft nephropathy [CAN] grade II and III) at the 20-year protocol biopsy compared with the two well-functioning grafts (CAN grade I and II). We conclude that the protocol biopsies even at 20 years can contribute to predict the fate of renal allografts.

RESUMEN / SUMMARY:  - Radiation nephropathy has emerged as a major complication of bone marrow transplantation (BMT) when total body irradiation (TBI) is used as part of the regimen. Classically, radiation nephropathy has been assumed to be inevitable, progressive, and untreatable. However, in the early 1990’s, it was demonstrated that experimental radiation nephropathy could be treated with a thiol-containing ACE inhibitor, captopril. Further studies showed that enalapril (a non-thiol ACE inhibitor) was also effective in the treatment of experimental radiation nephropathy, as was an AII receptor antagonist. Studies also showed that ACE inhibitors and AII receptor antagonists were effective in the prophylaxis of radiation nephropathy. Interestingly, other types of antihypertensive drugs were ineffective in prophylaxis, but brief use of a high-salt diet in the immediate post-irradiation period decreased renal injury. A placebo-controlled trial of captopril to prevent BMT nephropathy in adults is now underway. Since excess activity of the renin-angiotensin system (RAS) causes hypertension, and hypertension is a major feature of radiation nephropathy; an explanation for the efficacy of RAS antagonism in the prophylaxis of radiation nephropathy would be that radiation leads to RAS activation. However, current studies favor an alternative explanation, namely that the normal activity of the RAS is deleterious in the presence of radiation injury. On-going studies suggest that efficacy of RAS antagonists may involve interactions with a radiation-induced decrease in renal nitric oxide activity or with radiation-induced tubular cell proliferation. We hypothesize that while prevention (prophylaxis) of radiation nephropathy with ACE inhibitors, AII receptor antagonists, or a high-salt diet work by suppression of the RAS, the efficacy of ACE inhibitors and AII receptor antagonists in treatment of established radiation nephropathy depends on blood pressure control.  N.

RESUMEN / SUMMARY:  - The impact of prophylactic oral ganciclovir therapy on the incidence of cytomegalovirus (CMV) disease, patient and graft survival, and costs in patients receiving kidney and liver transplants is described. CMV disease is a common cause of morbidity and mortality in solid organ transplant recipients unless prophylactic drug therapy is used. Prophylactic oral ganciclovir therapy reduces the incidence of CMV disease in kidney and liver transplant recipients. It is more effective for recipients who are seronegative before the transplant and receive organs from seronegative (D-/R-) donors than in seronegative recipients of organs from seropositive (D+/R-) donors. CMV disease remains a problem in the latter. CMV disease increases the risk of graft failure, which decreases the likelihood of patient survival. The extent of matching of the DR subregion of the human leukocyte antigen complex in the donor and recipient may affect graft survival in patients with CMV disease. Graft failure is costly and should be considered in economic analyses of CMV prophylaxis regimens because of the potential impact of prophylaxis on CMV disease. The use of oral ganciclovir for CMV prophylaxis has reduced the incidence of CMV disease in kidney and liver transplant recipients.  N. Ref:: 10

RESUMEN / SUMMARY:  - BACKGROUND: Clinical trials in renal transplantation must use surrogate markers of long-term graft survival if conclusions are to be drawn at acceptable speed and cost. Morphologic changes in transplant biopsies provide the earliest available evidence of damage, and “protocol” biopsies from stable grafts can be used to reduce the number of patients needed in clinical trials. This approach has been inhibited by concerns over safety, but the risk of biopsy of a stable kidney, with no active inflammation or acute functional impairment, has never been formally estimated. METHODS: In accordance with a predefined set of questions, a retrospective audit of a sequential series of protocol biopsies was performed in four major transplant centers. RESULTS: A total of 2,127 biopsy events were assessed for major complications, and 1,486 were assessed for minor ones. There were no deaths. One graft was lost, under circumstances indicating that the loss should have been prevented. Three episodes of hemorrhage required direct intervention. Three further patients required transfusion. There were two episodes of peritonitis, but one was arguably an unrelated event. All serious complications presented within 4 hr of biopsy. CONCLUSIONS: The incidence of clinically significant complications after protocol biopsy of a stable renal transplant is low. Direct benefits to the patients concerned (irrespective of the benefit that may accrue in clinical trials) were not formally assessed but seem likely to outweigh the risk of the procedure. We believe that it is ethically justifiable to ask renal transplant recipients to undergo protocol biopsies in clinical trials and routine care.

RESUMEN / SUMMARY:  - GUIDELINES: A. Hyperlipidaemia risk profiles should be identified by regular screening (at least once a year) for cholesterol, HDL-cholesterol, LDL-cholesterol and triglyceride blood levels in renal transplant patients. B. In renal transplant patients, hyperlipidaemia must be treated in order to keep the cholesterol/lipid levels within recommended limits according to the number of risk factors. C. Management of hyperlipidaemia after renal transplantation should be the same as for the dialysis population, with, in addition, modification of the immunosuppressive protocol when appropriate. D. Patients should be carefully monitored for adverse effects of lipid-lowering agents or interactions with immunosuppressive drugs.

RESUMEN / SUMMARY:  - GUIDELINES: A. In order to reduce or avoid long-term serious adverse effects of corticosteroids, such as bone fractures, diabetes mellitus, arterial hypertension, osteoporosis and eye complications, steroid withdrawal should be considered. B. Steroid withdrawal is safe only in a proportion of graft recipients and is recommended only in low-risk patients. The efficacy of the remaining immunosuppression should be considered. C. After steroid withdrawal, graft function has to be monitored very carefully because of the risk of a delayed but continuous loss of function due to chronic graft dysfunction. In the case of functional deterioration or dysfunction, steroids should be re-administered. D. Cyclosporine withdrawal might be considered in order to ameliorate nephrotoxicity, arterial hypertension, lipid disorders and hypertrichosis. This can be carried out with no significant long-term risk of progressive graft loss. The efficacy of the remaining immunosuppression should be considered. After cyclosporine withdrawal, careful monitoring for acute rejection is recommended.

RESUMEN / SUMMARY:  - Decreases in transplant function may be attributable to a variety of conditions, including prerenal and postrenal failure, cyclosporin A (CsA) toxicity, polyoma nephritis, recurrent glomerulonephritis, and rejection. The diagnosis of rejection should therefore be made on the basis of a transplant biopsy of adequate size, before the initiation of any therapy. Pulse steroid treatment (three to five 0.25- to 1.0-g pulses of methylprednisolone, administered intravenously) is the usual first-line therapy and has a 60 to 70% success rate, although orally administered prednisone (0.25 g) may be just as efficacious. Even if reverted, any rejection should trigger an at least temporary increase in basal immunosuppression, consisting of an increase in CsA or tacrolimus target levels, the addition of steroids or an increase in their dosage, the addition of mycophenolate mofetil, or a switch from CsA to tacrolimus. The addition of rapamycin or its RAD derivative may fulfill the same purpose. Steroid resistance should not be assumed before the fifth day of pulse steroid treatment, although histologic features of vascular rejection may indicate the need for more aggressive treatment earlier. Steroid-resistant rejection is traditionally treated with poly- or monoclonal antilymphocytic antibodies, with success rates of 60 to 70%. Their potential benefit must be carefully balanced against the risks of infection and lymphoma. More recently, mycophenolate mofetil has been successfully used to treat steroid-resistant rejection, but only of the interstitial (cellular) type. Switching from CsA to tacrolimus for treating recurrent or antibody-resistant rejection is successful in approximately 60% of cases. Plasmapheresis and intravenously administered Ig have been used in some desperate cases, with surprising success. Because none of the available drugs has a significantly better profile of therapeutic versus adverse effects, the possible benefits of continued rejection therapy must be continuously balanced with the potential for serious, sometimes fatal, side effects.  N.

RESUMEN / SUMMARY:  - Cardiovascular disease is a major hazard limiting the life expectancy of renal transplant recipients and the most frequent cause of late allograft loss. Patients with renal disease have usually been exposed for both traditional, and for them unique, risk factors over a prolonged period of time and may carry the burden of advanced atherosclerotic disease already at the time of transplantation. The observed survival benefit of transplantation is probably from elimination of the numerous uremia-related risk factors. However, immunosuppressive therapy and the chronic inflammatory state, together with genetic susceptibility and not infrequently impaired renal function, may bring about new potentially atherogenic conditions. Metabolic risk factors may jeopardize both patient and graft survival. Several observational studies provide evidence for the negative impact of preexisting metabolic abnormalities on long-term outcomes. Identification of modifiable cardiovascular risk factors may enable risk reduction also in renal transplant recipients. Results of ongoing intervention trials are awaited. The observed improvement of patient survival after renal transplantation during the past decade may reflect the increasing awareness and more optimal care of patients throughout the course of renal disease.  N.

RESUMEN / SUMMARY:  - BACKGROUND: Chronic allograft rejection (CR) is the major cause of failure of long-term graft survival and is so far irreversible. Early prognosis of CR by molecular markers before overt histologic manifestation would be a valuable aid for the optimization of treatment regimens and the design of clinical CR trials. Oligonucleotide microarray-based approaches have proven to be useful for the diagnosis and prognosis of a variety of diseases and were chosen for the unbiased identification of prognostic biomarkers. METHODS: Renal allograft biopsies were taken at month 6 posttransplantation (PT) from two groups who were, at that time, healthy recipients: one group developed CR at month-12 PT, the other group remained healthy. Gene expression profiles from the two groups at month-6 PT biopsies were analyzed to identify differentially expressed genes with prognostic value for CR development at month 12. RESULTS: A set of 10 genes was identified that showed differential expression profiles between the two patient groups and had a complete separation of the 15% to 85% quantile range for each individual gene. This set of genes was sufficient to allow the correct prediction of the occurrence or nonoccurrence of CR in 15 of 17 (88%) patients using cross-validation (occurrence for a patient was predicted on the basis of the other patients’ data only). In addition, a correct prediction could be made that a recipient with a normal biopsy 12 months PT developed CR within the following 6 months. CONCLUSIONS: Identified expression patterns seem to be highly prognostic of the development of renal CR.

RESUMEN / SUMMARY:  - GUIDELINES: A. Tuberculosis (TB) is not rare after renal transplantation, and can be life-threatening. Treatment of active TB in renal transplant recipients should be the same as in the general population, i.e. 2 months of quadruple therapy combining rifampin, isoniazid, ethambutol and pyrazinamide, followed by a 4-months double therapy with isoniazid and rifampin. The drug ethambutol should not be used initially if the rate of resistance to isoniazid is less than 4% in the community. B. As rifampin will reduce the plasma concentration of calcineurin antagonists and rapamycin, the blood levels of these agents must be monitored closely. Rifabutin may be used as an alternative to rifampin, as this drug is a less potent inducer of the microsomal P450 enzymes. C. Renal transplant candidates and renal transplant recipients should be screened for latent TB infection. Patients considered to have latent TB infection are defined as: (i) those who display a 5 mm (renal transplant recipients) or a 10 mm (dialysis patients) induration after tuberculin skin testing; (ii) those with chest X-ray images suggestive of past TB infection; (iii) those with a history of past TB infection that was not treated adequately; and (iv) those who have been in close contact with infectious patients. The preferred treatment of latent TB infection is isoniazid 300 mg/day for 9 months.

INSTITUCIÓN / INSTITUTION:  - Royal Free and University College Hospital Medical School, Centre for Nephrology, Royal Free Hospital, London, UK. andrew.davenport@rfh.nthames.nhs.uk

RESUMEN / SUMMARY:  - The patient with an acute brain injury requiring renal replacement therapy presents a major problem in that conventional intermittent hemodialysis may exacerbate the injury by compromising cerebral perfusion pressure, either after a reduction in cerebral perfusion or because of increased cerebral edema. Compared with standard intermittent hemodialysis, the continuous forms of renal replacement therapy (CRRT) provide an effective therapy in terms of solute clearance, coupled with improved cardiovascular and intracranial stability. The disadvantage of CRRT is that anticoagulation may be required, and anticoagulants with systemic effects may provoke intracerebral hemorrhage, either at the site of damage or around the intracranial pressure monitoring device. Although peritoneal dialysis does not require anticoagulation, the clearances achieved are often less than those of CRRT, and sudden changes in intraperitoneal volume may provoke cardiovascular and thus intracranial instability.  N.

RESUMEN / SUMMARY:  - The current knowledge of the pathogenesis of post-transplant glucose intolerance is sparse. This study was undertaken to assess the relative importance of insulin secretion (ISec) and insulin sensitivity (IS) in the pathogenesis of post-transplant diabetes mellitus (PTDM), impaired glucose tolerance (IGT) and impaired fasting glucose (IFG) after renal transplantation. An oral glucose tolerance test (OGTT) was performed in 167 non-diabetic recipients 10 wk after renal transplantation. Fasting, 1-h and 2-h insulin and glucose levels were used to estimate the insulin secretory response and IS. One year after transplantation 89 patients were re-examined with an OGTT including measurements of fasting and 2 h glucose. Ten weeks after transplantation the PTDM-patients had significantly lower ISec and IS than patients with IGT/IFG, who again had lower ISec and IS than those with normal glucose tolerance (NGT). One year later, a similar difference in baseline ISec was observed between the three groups, whereas baseline IS did not differ significantly. Patients who improved their glucose tolerance during the first year, were mainly characterized by a significantly greater baseline ISec, and they received a significantly higher median prednisolone dose at baseline with a subsequent larger dose reduction during the first year, than the patients who had their glucose tolerance unchanged or worsened. In conclusion, both impaired ISec and IS characterize patients with PTDM and IGT/IFG in the early course after renal transplantation. The presence of defects in insulin release, rather than insulin action, indicates a poor prognosis regarding later normalization of glucose tolerance.  N. Ref:: 29

RESUMEN / SUMMARY:  - Transplantation is the preferred organ replacement therapy for most patients with end-stage renal disease. Despite impressive improvements over recent years in the treatment of acute rejection, approximately half of all grafts will loose function within 10 years after transplantation. Chronic renal transplant dysfunction, also known as transplant atherosclerosis, is a leading cause of late allograft loss. To date, no specific treatment for chronic renal transplant dysfunction is available. Although its precise pathophysiology remains unknown, it is believed that it involves a multifactorial process of alloantigen-dependent and alloantigen-independent risk factors. Obesity, posttransplant diabetes mellitus, dyslipidemia, hypertension, and proteinuria have all been identified as alloantigen-independent risk factors. Notably, these recipient-related risk factors are well-known risk factors for cardiovascular disease, which cluster within the insulin resistance syndrome in the general population. Insulin resistance is considered the central pathophysiologic feature of this syndrome. It is therefore tempting to speculate that it is insulin resistance that underlies the recipient-related risk factors for chronic renal transplant dysfunction. Recognition of insulin resistance as a central feature underlying many, if not all, recipient-related risk factors would not only improve our understanding of the pathophysiology of chronic renal transplant dysfunction, but also stimulate development of new treatment and prevention strategies.  N.

In the case of a discrepancy between the drug dose and signs of toxicity, then a thorough pharmacokinetic analysis should be performed. C. Cardiovascular, renal and metabolic risks and the risk of de novo malignancy must be considered in a long-term monitoring programme.

RESUMEN / SUMMARY:  - Basiliximab (Simulect), a chimeric (human/murine) monoclonal antibody, is indicated for the prevention of acute organ rejection in adult and paediatric renal transplant recipients in combination with other immunosuppressive agents.Basiliximab significantly reduced acute rejection compared with placebo in renal transplant recipients receiving dual- (cyclosporin microemulsion and corticosteroids) or triple-immunotherapy (azathioprine- or mycophenolate mofetil-based); graft and patient survival rates at 12 months were similar. Significantly more basiliximab than placebo recipients were free from the combined endpoint of death, graft loss or acute rejection 3 years, but not 5 years, after transplantation.The incidence of adverse events was similar in basiliximab and placebo recipients, with no increase in the incidence of infection, including cytomegalovirus (CMV) infection. Malignancies or post-transplant lymphoproliferative disorders after treatment with basiliximab were rare, with a similar incidence to that seen with placebo at 12 months or 5 years post-transplantation. Rare cases of hypersensitivity reactions to basiliximab have been reported.The efficacy of basiliximab was similar to that of equine antithymocyte globulin (ATG) and daclizumab, and similar to or greater than that of muromonab CD3. Basiliximab was as effective as rabbit antithymocyte globulin (RATG) in patients at relatively low risk of acute rejection, but less effective in high-risk patients. Numerically or significantly fewer patients receiving basiliximab experienced adverse events considered to be related to the study drug than ATG or RATG recipients. The incidence of infection, including CMV infection, was similar with basiliximab and ATG or RATG.Basiliximab plus baseline immunosuppression resulted in no significant differences in acute rejection rates compared with baseline immunosuppression with or without ATG or antilymphocyte globulin in retrospective analyses conducted for small numbers of paediatric patients. Limited data from paediatric renal transplant recipients suggest a similar tolerability profile to that in adults. Basiliximab appears to allow the withdrawal of corticosteroids or the use of corticosteroid-free or calcineurin inhibitor-sparing regimens in renal transplant recipients.Basiliximab did not increase the overall costs of therapy in pharmacoeconomic studies.CONCLUSION: Basiliximab reduces acute rejection without increasing the incidence of adverse events, including infection and malignancy, in renal transplant recipients when combined with standard dual- or triple-immunotherapy. The overall incidence of death, graft loss or acute rejection was significantly reduced at 3 years; there was no significant difference for this endpoint 5 years after transplantation. Malignancy was not increased at 5 years. The overall efficacy, tolerability, ease of administration and cost effectiveness of basiliximab make it an attractive option for the prophylaxis of acute renal transplant rejection.  N. Ref:: 85

RESUMEN / SUMMARY:  - BACKGROUND: Mucormycosis is a rare and opportunistic infection usually associated with hematologic diseases, diabetes mellitus, renal failure, solid tumors, and organ transplantation. METHODS: We present five cases of mucor infection after transplantation (three after a series of 750 orthotopic liver transplantation and two after a series of 13 simultaneous pancreas-kidney transplantation in patients with type 1 diabetes) subjected to medical and surgical treatment and analyze the factors related to the development of this infection. RESULTS: The clinical forms were two cutaneous (laparotomy wound or prior surgical drain site), two rhino-maxillary, and one pulmonary. As risk factors for mucormycosis all patients had pre- or posttransplantation diabetes, and showed at least one episode of acute rejection that required aggressive immunosuppression (2-7 g of methylprednisolone; also three patients were treated with antithymocyte globulin [ATG] monoclonal antibody [orthoclone and/or OKT3]). We also found renal failure, acidosis, malnutrition, and Candida and cytomegalovirus infections as factors related to mucor infection. Diagnosis of fungal infection was confirmed by exudate or fluid culture in three cases and by biopsy in two. All patients were treated with liposomal amphotericin B (from 3.5 to 5.6 g of total dose) and resection until the surgical margins were free of infection. All patients survived after this severe infection. CONCLUSIONS: With an early diagnosis of mucormycosis by clinical findings, culture, or tissue biopsy, and aggressive treatment consisting of administration of liposomal amphotericin B and surgical resection of all infected tissue, excellent results are achieved.  N.

RESUMEN / SUMMARY:  - BACKGROUND: Thrombotic microangiopathy (TMA) is a well-recognized and serious complication of renal transplantation, affecting 3% to 14% of patients administered calcineurin-inhibitor-based immunosuppression. METHODS: We reviewed 1,219 biopsy reports of 742 kidney and kidney-pancreas transplants performed during 15 years at our center and found 21 biopsy-confirmed cases of TMA. RESULTS: On presentation, the majority (62%) had systemic TMA with manifest hemolysis and thrombocytopenia, whereas a subset had TMA localized only to the graft (38%). There were no statistically significant differences in sex, type of transplant, age, race, or type of immunosuppression. Patients with systemic TMA were more likely to be treated with plasma exchange (38% versus 13%; P < 0.05), more often required dialysis therapy (54% versus 0%; P = 0.01), and had a greater rate of graft loss (38% versus 0%; P < 0.05). No patient with the localized variant had TMA-related graft loss. Patients with localized TMA often responded to reduction, conversion, or temporary discontinuation of calcineurin-inhibitor-based immunosuppression therapy and did not routinely require plasma exchange for graft salvage. We compare our findings with the literature regarding the prognosis of TMA. CONCLUSION: Classifying patients with post-renal transplantation TMA into those with localized and systemic disease is clinically useful because each group has distinct characteristics and clinical courses.  N.

RESUMEN / SUMMARY:  - Hypertension (HTN) contributes to the high incidence of cardiovascular disease mortality as well as chronic allograft nephropathy (CAN) and late graft failure in renal transplant recipients. The mechanisms are complex and may involve pathogenic factors attributable to the host, allograft, and immunosuppressive drugs. Calcium channel blockers should be used to ameliorate the nephrotoxicity of calcineurin inhibitors in the early years after transplantation. Angiotensin-converting enzyme inhibitors and angiotensin-2 type-1 receptor blockers are safe and effective, have antiproteinuric effects, slow the progression of CAN, and may provide survival benefits. Diuretics and/or beta-adrenergic receptor blockers are frequently added in combination regimen. Appropriate adjustment of the immunosuppressive drugs should also be considered for the long-term care of kidney recipients with HTN.  N. Ref:: 53

RESUMEN / SUMMARY:  - Post-transplant lymphoproliferative disorders (PTLD) are a group of heterogeneous lymphoid proliferations in chronic immunosuppressed recipients which appear to be related to Epstein Barr Virus (EBV). Receptor EBV seronegativity, use of antilymphocyte antibodies and CMV disease have been identified as risk factors that may tigger development of PTLD. We have studied the incidence of PTLD and its relationship with EBV in 588 adult renal transplant recipients who were transplanted in our hospital from 1988 to 2001. We have also evaluated the diagnostic and therapeutic methods used, the risk factors and outcome of the patients who developed PTLD. We identified 8 recipients (4 males and 4 females), range from 18 to 67 years (mean age 45.6 years) with a median time between grafting and PTLD of 4.1 years (0.1-7 years), who developed PTLD (1.3%). Only 1 patient received OKT3 and had CMV disease, two of them (25%) had been treated with hight doses of prednisolone, another was EBV seronegative, but the rest of them (50%) had no risk factors. Two patients were diagnosed at autopsy, the diagnosis of 5 was based on the histology of biopsy and the last one by CT scans of chest-abdomen and cytology. The presence of EBV in the lymphoproliferative cells was assessed in 5 out of the 7 studied patients (71.4%). The outcome of our recipients was poor. Five out of 8 patients died shortly after diagnosis as a direct consecuence of PTLD and another of an infectious complication of the treatment (75%). The 2 patients alive started dialysis and 1 of them died 2 years later of a non-related cause. In conclusion, PTLD is a relatively frequent disease with a poor prognosis in renal transplant patients. It seems to have a close relationship with EBV and can develop in the absence of the classical risk factors.  N. Ref:: 18

RESUMEN / SUMMARY:  - GUIDELINE: All recipients of an allogeneic kidney graft should take life-long maintenance immunosuppressive medication. Whereas there is no immunological test to diagnose chronic allograft dysfunction, circumstantial evidence suggests that immunological factors play an important role in its pathogenesis. This evidence is based on experimental data, the beneficial effect of sharing HLA antigens between donor and recipient and post-transplantation immunological monitoring studies.

RESUMEN / SUMMARY:  - BACKGROUND: In a recent single-center study, donor use of catecholamines was identified to reduce kidney allograft rejection. This study investigates the effects of donor employment of adrenergic agents on graft survival in a large data base, including liver and heart transplants. METHODS: The study was based on the registry of the Eurotransplant International Foundation including 2415 kidney, 755 liver, and 720 heart transplants performed between January 1 and December 31, 1993. A total of 1742 donor record forms referring to the cadaveric donor activities in 1993 were systematically reviewed with regard to employment of adrenergic agents. Catecholamine use was simply coded dichotomously and divided into three strata according to zero, single, and combined application. Multivariate Cox regression including age, gender, cause of brain death, cold ischemia, HLA-mismatching, number of previous transplants, and urgency in liver transplants was applied for statistical analysis. RESULTS: Donor employment of catecholamines was associated with increased 4-year graft survival after kidney transplantation (hazard ratio [HR], 0.85; 95% confidence interval [95% CI], 0.74-0.98). The benefit is conferred in a dose-dependent manner and compares in quantitative terms with prospective HLA matching on class I and class II antigens (HR, 0.90; 95% CI, 0.84-0.97). Use of norepinephrine was predictive of initial nonfunction after heart transplantation (HR, 1.66; 95% CI, 1.14-2.43), but did not compromise liver grafts (HR, 0.94; 95% CI, 0.67-1.32). CONCLUSIONS: Optimizing the management of brain-dead organ donors, including the possibility of selective administration of adrenergic agents, may provide a major benefit on graft survival without adverse side effects for the recipients. Further investigation on best use of adrenergic drugs, optimum dosage, and duration is warranted.

RESUMEN / SUMMARY:  - GUIDELINES: A. Any significant deterioration in graft function should be investigated using the appropriate diagnostic tools and, if possible, therapeutic interventions should be initiated. The usual causes of a decline in glomerular filtration rate after the first year include transplant-specific causes such as chronic allograft nephropathy, acute rejection episodes, chronic calcineurin inhibitor nephrotoxicity, transplant renal artery stenosis and ureteric obstruction, as well as immunodeficiency-related causes and non-transplant-related causes, such as recurrent or de novo renal diseases and bacterial infections. B. Any new onset and persistent proteinuria of >0.5 g/24 h should be investigated and therapeutic interventions should be initiated. The usual causes include chronic allograft nephropathy and transplant glomerulopathy, and recurrent or de novo glomerulonephritis.

RESUMEN / SUMMARY:  - There have been only five reported cases of primary posttransplant T-cell lymphoma. We report the first case associated with the use of sirolimus (Rapamycin, Wyeth-Ayerst, Philadelphia, PA). The patient, receiving prednisone, cyclosporine, and sirolimus treatment, developed ascites, diarrhea, and weight loss 7 months after his second renal transplant. Tissue obtained at laparotomy established the diagnosis of primary T-cell lymphoma. Latent membrane protein-1 for Epstein-Barr virus was negative, but in-site hybridization test for Epstein-Barr-encoded RNA was positive. Despite aggressive chemotherapy, the patient died 8 months posttransplant. This is the sixth reported case of primary intestinal posttransplant T-cell lymphoma, but it is the first case associated with the use of sirolimus. The incidence of posttransplant lymphoproliferative disease in patients receiving sirolimus should be studied.  N. Ref:: 6

RESUMEN / SUMMARY:  - Early after renal transplantation (RT) a rapid decrease in bone mineral density at the lumbar spine, femoral neck, and femoral shaft has been documented. In addition, an appreciable proportion of patients still remain losing bone late after RT. As a consequence, RT patients are at a high risk of bone fractures as compared to general population. Most fractures involve appendicular skeleton, particularly the feet and ankles, and the diabetic patient is at increased risk of fractures. Thus, early institution of preventive measures and treatment of established osteoporosis are central. The major cause of post-transplantation bone loss is corticosteroid treatment, and this should be used at the lower dose compatible with graft survival. Preexisting hyperparathyroidism also affects the early cancellous bone loss at the spine, and post-transplantation bone loss reflects variable individual susceptibility, resembling the polygenic determination of bone mineral density in general. Clinical trials have demonstrated that bisphosphonates or vitamin D plus calcium supplementation, prevent post-transplantation bone loss during the first 6-12 months. However, their role in preventing bone fractures has not been proven. Finally, recommendations for management, prevention and treatment, are summarized.  N. Ref:: 24

RESUMEN / SUMMARY:  - GUIDELINES: A. Renal transplantation restores fertility, and successful pregnancies have been reported in renal transplant women. In women with normal graft function, pregnancy usually has no adverse effect on graft function and survival. Therefore, women of childbearing age who consider pregnancy should receive complete information and support from the transplant team. B. Pregnancy could be considered safe about 2 years after transplantation in women with good renal function, without proteinuria, without arterial hypertension, with no evidence of ongoing rejection and with normal allograft ultrasound. C. Pregnancy after transplantation should be considered a high-risk pregnancy and should be monitored by both an obstetrician and the transplant physician. Pregnancy should be diagnosed as early as possible. The principal risks are infection, proteinuria, anaemia, arterial hypertension and acute rejection for the mother, and prematurity and low birth weight for the foetus. D. Pregnant women and transplanted patients are at increased risk of infections, especially bacterial urinary tract infections and acute pyelonephritis of the graft. Urine cultures should be performed monthly and all asymptomatic infections should be treated. Monitoring of viral infections is also recommended. (Evidence level B) E. Acute rejection episodes are uncommon but may occur after delivery. Therefore, immunosuppression should be re-adjusted immediately after delivery. F. Because pre-eclampsia develops in 30% of pregnant patients, especially those with prior arterial transplant hypertension, blood pressure, renal function, proteinuria and weight should be monitored every 2-4 weeks, with more attention during the third trimester. Anti-hypertensive agents should be changed to those tolerated during pregnancy. ACE inhibitors and angiotensin II receptor antagonists are absolutely contra-indicated. G. Immunosuppressive therapy based on cyclosporine or tacrolimus with or without steroids and azathioprine may be continued in renal transplant women during pregnancy. Other drugs, such as mycophenolate mofetil and sirolimus, are not recommended based on current information available. Because of drug transfer into maternal milk, breastfeeding is not recommended. H. Vaginal delivery is recommended, but caesarean section is required in at least 50% of cases. Delivery should occur in a specialized centre. In the puerperium, renal function, proteinuria, blood pressure, cyclosporine/tacrolimus blood levels and fluid balance should be closely monitored.

RESUMEN / SUMMARY:  - A regimen combining sirolimus, tacrolimus, and daclizumab has recently been shown to provide adequate immunosuppression for allogeneic islet transplantation in humans, but remains unproven for primarily vascularized allografts. We evaluated this regimen for renal allograft transplantation in mismatched nonhuman primates. Dosages of sirolimus and tacrolimus were adjusted for trough levels of 10-15 ng/mL and 4-6 ng/mL, respectively. Treated monkeys (n = 5) had significantly prolonged allograft survival, with a mean survival of 36 days vs. 7 days in untreated controls (n = 6, p = 0.008). Four of five treated animals, but none of the controls, developed fibrinoid vascular necrosis of the small intestine. A review of gut histology from animals on other immunosuppressive protocols performed by our laboratory suggested that these lesions were a result of sirolimus exposure. In summary, this regimen prolongs the survival of vascularized renal allografts, but is limited by profound GI toxicity in rhesus macaques.

RESUMEN / SUMMARY:  - According to the analysis of the Collaborative Transplant Study (CTS), the incidence of renal carcinoma in patients with renal transplantation as well as with heart transplantation is significantly increased at any given patient age. The cumulative incidence 10 years after kidney transplantation is 185 per 100,000 patients in children below the age of 19 years at the time of transplantation. Age and immunosuppressive treatment seem to be the major risk factors. The majority of cancers develop within the native kidneys. Chronic transplant nephropathy and accelerated senescence may be further risk factors for the development of cancer within a kidney transplant. Growth hormone (GH) treatment could not be identified as an additional risk factor.  N. Ref:: 26

RESUMEN / SUMMARY:  - Posttransplantation hypertension has been identified as an independent risk factor for chronic allograft dysfunction and loss. Based on available morbidity and mortality data, posttransplantation hypertension must be identified and managed appropriately. During the past decade, calcium channel blockers have been recommended by some as the antihypertensive agents of choice in this population, because it was theorized that their vasodilatory effects would counteract the vasoconstrictive effects of the calcineurin inhibitors. With increasing data becoming available, reexamining the use of traditional antihypertensive agents, including diuretics and beta-blockers, or the newer agents, angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers, may be beneficial. Transplant clinicians must choose antihypertensive agents that will provide their patients with maximum benefit, from both a renal and a cardiovascular perspective. Beta-blockers, diuretics, and ACE inhibitors have all demonstrated significant benefit on morbidity and mortality in patients with cardiovascular disease. Calcium channel blockers have been shown to possess the ability to counteract cyclosporine-induced nephrotoxicity. When compared with beta-blockers, diuretics, and ACE inhibitors, however, the relative risk of cardiovascular events is increased with calcium channel blockers. With the long-term benefits of calcium channel blockers on the kidney unknown and a negative cardiovascular profile, these agents are best reserved as adjunctive therapy to beta-blockers, diuretics, and ACE inhibitors.  N.

RESUMEN / SUMMARY:  - Cardiomyopathy and IHD are important morbid complications among renal transplant recipients. Age, diabetes, and sex remain important markers of risk. Smoking, hyperlipidemia, and hypertension appear to be the major reversible risk factors for IHD. Anemia and hypertension predict CHF. Definitive evidence on optimal intervention is lacking. Similarities in the renal transplant recipients to CRI patients with respect to cardiomyopathy and to the general population with respect to IHD suggest that extrapolation from those groups is reasonable in the interim.  N.

RESUMEN / SUMMARY:  - BACKGROUND: The role of cytomegalovirus (CMV) in chronic kidney allograft rejection remains controversial. The purpose of this study was to examine the impact of CMV infection on histopathologic changes in 6-month protocol biopsy specimens of kidney allografts. METHODS: Altogether, 52 renal allograft recipients were studied. CMV infection was diagnosed by CMV antigenemia test, viral cultures from blood and urine, or both. CMV was demonstrated in the biopsy specimens by antigen detection and hybridization in situ. Acute rejections were diagnosed by biopsy histology, and biopsy specimens were graded according to the Banff ‘97 classification. RESULTS: CMV infection was diagnosed in 41 patients. The 11 patients in whom CMV infection was not detected were used as controls. Acute rejection was diagnosed in 22 of 41 CMV patients and in 6 of 11 control patients. CMV was demonstrated in the biopsy specimens of 19 of 41 CMV patients. CMV was not associated with increased glomerular, tubular, or interstitial changes. However, the arteriosclerotic changes in small arterioles were significantly increased in the subgroup of patients where CMV was demonstrated in the graft as compared with controls (P<0.01). Analysis of the impact of acute rejection on arteriolar thickening showed that only a positive history of both acute rejection and CMV found in the graft was associated with significantly increased vascular changes compared with CMV-free recipients (P<0.05). CONCLUSIONS: Neither CMV nor acute rejection alone was associated with increased vascular or other histopathologic changes in 6-month protocol biopsy specimens of kidney allografts, but a previous history of both acute rejection and the presence of CMV in the graft was associated with increased vascular changes.

RESUMEN / SUMMARY:  - Gross hematuria, graft pain, and rising serum creatinine are classic signs of acute rejection, obstruction, or bacterial pyelonephritis for patients with renal transplants. This presentation often prompts percutaneous renal allograft biopsy. If subsequent evaluation fails to show evidence of acute rejection, obstruction, or bacterial infection, viral etiologies should be considered. We report a 14-year-old Hispanic female with a living-related renal transplant who had gross hematuria, graft tenderness, and increased serum creatinine, but did not have evidence of acute rejection, obstruction, or bacterial pyelonephritis. To our knowledge, this is the first report of adenovirus pyelonephritis in a transplanted kidney of a pediatric patient, with isolation of adenovirus in the urine and in the allograft using immunocytochemical techniques.  N.

RESUMEN / SUMMARY:  - Hepatitis C virus (HCV) infection is a common problem in renal transplant patients, associated with an increase in morbidity and mortality. HCV infection is associated with a lower graft and patient survival. The problem of HCV infection is the increase in viral load and liver transaminases after renal transplantation secondary to immunosuppressive therapy. After renal transplantation, interferon therapy is not recommended because of the risk for acute rejection and acute nephritis. In this context, it is absolutely necessary to consider the evaluation and treatment of HCV infection during the dialysis period. Several studies have defined the benefits of interferon therapy in dialysis patients, with rates of maintenance response significantly higher than in the general population. The difference in the pharmacokinetic profile of interferon in dialysis patients could justify its higher efficacy.  N. Ref:: 17

RESUMEN / SUMMARY:  - GUIDELINES: A. In the case of recurrent focal and segmental glomerulosclerosis (FSGS), aggressive treatment with high-dose cyclosporine in children, ACE inhibitors and/or Angiotensin II antagonists, plasma exchange or immunoadsorption may result in remission in some patients. B. In the case of recurrent membranous nephropathy (MN), there is no specific treatment. However, control of risk factors, such as hypertension, heavy proteinuria and hyperlipidaemia, and prevention of thrombotic complications are recommended. C. In the case of recurrent membranoproliferative glomerulonephritis (MPGN), there is no specific treatment. However, control of risk factors, such as hypertension, heavy proteinuria and hyperlipidaemia, and prevention of thrombotic complications are recommended. D. In the case of recurrent IgA glomerulonephritis, use of additional steroids is not yet a validated treatment. The control of risk factors, such as hypertension, heavy proteinuria and hyperlipidaemia, is recommended. E. In the rare case of recurrent anti-glomerular basement membrane (anti-GBM) glomerulonephritis with reappearance of anti-GBM antibodies, it is recommended to initiate plasma exchange and to treat with appropriate immunosuppressive agents (e.g. cyclophosphamide).

RESUMEN / SUMMARY:  - GUIDELINES. A. Whereas immunological mechanisms dominate in the initiation and propagation of the injury that leads to chronic allograft dysfunction and nephropathy, there is circumstantial evidence that non-immunological factors, such as advanced donor age, hyperfiltration, overweight, delayed graft function, heavy proteinuria, smoking, arterial hypertension, hypercholesterolaemia and hypertriglyceridaemia, play a role as aggravating or progression factors. It is recommended to prevent or, if possible, treat all these factors. B. As arterial hypertension is very frequent among renal transplant patients and associated with increased graft (and patient) loss, it is recommended to aim at a blood pressure less than 130/85 mmHg in renal transplant patients and <125/75 mmHg in recipients with proteinuria >1 g/day.

RESUMEN / SUMMARY:  - OBJECTIVES: To report our results after antegrade endoscopic treatment of ureteral stenosis with balloon dilation with or without holmium laser endoureterotomy. Ureteral stenosis is the most common long-term urologic complication of renal transplantation. METHODS: From July 2000 to October 2002, 9 renal transplant patients with ureteral obstruction diagnosed by an increase in serum creatinine and radiologic evidence presented for endoscopic treatment. All patients were treated with nephrostomy tube drainage followed by antegrade flexible nephroureteroscopy and balloon dilation of the stricture. Three patients required holmium laser endoureterotomy during the same procedure because of fluoroscopic and endoscopic evidence of persistent stricture. All patients were treated with ureteral stents and nephrostomy tubes postoperatively. The median follow-up was 24 months (range 6 to 32). RESULTS: The site of stenosis was at the ureterovesical anastomosis in all patients, and the mean stricture length was 0.28 cm. Two patients had previously undergone ureteroneocystostomy for prior ureteral stenosis. Six patients (66%) required only balloon dilation, and 3 patients (33%) also required holmium laser endoureterotomy. The median ureteral stent and nephrostomy tube duration was 40 and 62 days, respectively. The mean serum creatinine level was 2.3 mg/dL at presentation and 1.7 mg/dL at the last follow-up visit. After a median follow-up of 24 months, the ureteral patency and graft function rates were both 100%. No perioperative complications occurred. CONCLUSIONS: Balloon dilation with or without holmium laser endoureterotomy was successful and safe in this group of renal transplant patients with short ureterovesical anastomotic strictures.  N.

TÍTULO / TITLE:  - Hormone replacement therapy in postmenopausal women with end-stage renal disease: a review of the issues.

REVISTA / JOURNAL:  - Semin Dial 2001 May-Jun;14(3):146-9.

AUTORES / AUTHORS:  - Holley JL; Schmidt RJ

RESUMEN / SUMMARY:  - Hormone replacement is an integral part of therapies to prevent osteoporosis in postmenopausal women and may be considered a component in the treatment of dyslipidemia, cardiovascular disease, and possibly cognitive function. The indications for, and efficacy and prescription of, hormone replacement therapy in postmenopausal women with ESRD have been infrequently studied and less than 10% of postmenopausal women on dialysis are receiving hormone replacement. Small studies suggest that hormone replacement therapy is valuable in treating the dyslipidemia of women on dialysis, but indicate that a reduction in the dosage of hormone replacement may be needed. A potential role for hormone replacement therapy in the treatment and/or prevention of osteoporosis and sexual dysfunction in postmenopausal women on dialysis exists as well.  N. Ref:: 33

RESUMEN / SUMMARY:  - GUIDELINES: A. Because anaemia is relatively common after kidney transplantation, regular screening and careful evaluation of its causes are recommended. In many cases, post-transplant anaemia is caused by allograft dysfunction. The use of purine synthesis inhibitors (azathioprine and MMF), ACE inhibitors and angiotensin II receptor antagonists may frequently cause post-transplant anaemia. Anaemia is reversible after withdrawing the offending agent. Haemolytic anaemia may develop in transplant recipients. B. Treatment of anaemia should follow the European best practice guidelines for treatment of anaemia in chronic renal failure.

RESUMEN / SUMMARY:  - Cardiovascular complications contribute to a significant proportion of the morbidity and mortality in renal transplant patients. Underlying disease states such as diabetes and hypertension as well as risk factors associated with chronic dialysis may cause many patients to have established coronary artery and peripheral vascular disease at the time of transplantation. Progression or new onset of disease can occur after transplantation due to the continued presence of risk factors for cardiovascular disease. The benefit of modification of these risk factors such as hypertension and hyperlipidemia has been well established in the general population and has more recently been explored in the renal transplant population, although long-term studies documenting an improvement in morbidity and mortality are not available. This article focuses on the potential benefit of modification of risk factors in this setting.  N. Ref:: 90

RESUMEN / SUMMARY:  - The high incidence of hypertension after renal transplantation contributes to the risk of cardiovascular morbidity and mortality in renal transplant recipients. Although cyclosporine has been influential in the improvement of transplant outcome, it has emerged as a major cause of hypertension after organ transplantation. The underlying pathophysiological mechanisms of cyclosporine-induced hypertension include enhanced sympathetic nervous system activity, renal vasoconstriction, and sodium/water retention. Hypertension is also significantly associated with reduced graft survival and thereby requires aggressive treatment intervention. Calcium channel blockers may offer some advantages over angiotensin-converting enzyme inhibitors for the treatment of hypertension in stable renal transplant recipients. Nevertheless, selection of the most appropriate antihypertensive agent should take into account the possibility of pharmacokinetic interactions with immunosuppressive agents. There is evidence to suggest that the use of tacrolimus-based immunosuppression induces less hypertension compared with cyclosporine. Not only do patients receiving tacrolimus tend to require less antihypertensive therapy, but converting patients from cyclosporine to tacrolimus has been shown to result in significant reductions in blood pressure. Thus, tacrolimus may be associated with an improved cardiovascular risk profile in renal transplant recipients.  N. Ref:: 26

INSTITUCIÓN / INSTITUTION:  - Department of General Surgery, University of Maastricht, PO Box 616, 6200 MD Maastricht, The Netherlands.

RESUMEN / SUMMARY:  - Ischemia followed by reperfusion (I/R) has cardinal implications in the pathogenesis of organ transplantation and rejection. Apoptosis and inflammation are central mechanisms leading to organ damage in the course of renal I/R. General aspects of apoptosis, morphology, induction, and biochemistry are discussed. Activated caspases, the classical effector enzymes of apoptosis, are able to induce not only apoptosis but also inflammation after I/R in experimental models. This redefines the involvement of apoptosis in I/R injury toward a central and functional role in the development of organ damage. Our purpose is to assess aspects of apoptosis and inflammation in terms of involvement in the pathogenesis of I/R-induced organ damage. Moreover, the implications of recent experimental advances for diagnosis and treatment of renal I/R injury in clinical practice will be discussed.  N. Ref:: 101

RESUMEN / SUMMARY:  - Fabry disease is a rare X-linked disorder, characterized by deficient activity of the lysosomal enzyme alpha-galactosidase A. This leads to systemic accumulation of the glycosphingolipid globotriaosylceramide (Gb3) in all body tissues and organs, including the kidney. Renal manifestations are less evident in female heterozygotes than in male hemizygotes, according to the Lyon hypothesis. Accumulation of Gb3 occurs mainly in the epithelial cells of Henle’s loop and distal tubule, inducing early impairment in renal concentrating ability; involvement of the proximal tubule induces Fanconi syndrome. All types of glomerular cells are involved, especially podocytes, and glomerular proteinuria may occur at a young age. The evolution of renal Fabry disease is characterized by progressive deterioration of renal function to end-stage renal failure (ESRF). Ultrastructural study of kidney biopsies reveals typical bodies in the cytoplasm of all types of renal cells, characterized by concentric lamellation of clear and dark layers with a periodicity of 35-50 A. Management of progressive renal disease requires dietetic and therapeutic strategies, usually indicated in developing chronic renal failure, with dialysis and renal transplantation required for patients with ESRF. The recent development of enzyme replacement therapy, however, should make it possible to prevent or reverse the progressive renal dysfunction associated with Fabry disease.  N. Ref:: 17

RESUMEN / SUMMARY:  - The worsening shortage of cadaver donor kidneys has prompted use of expanded or marginal donor kidneys (MDK), i.e. older age or donor history of hypertension or diabetes. MDK may be especially susceptible to calcineurin-inhibitor (CI) mediated vasoconstriction and nephrotoxicity. Similarly, early use of CI in patients with delayed graft function may prolong ischaemic injury. We developed a CI-free protocol of antibody induction, sirolimus, mycophenolate mofetil, and prednisone in recipients with MDK or DGF. METHODS: Adult renal transplant recipients who received MDK or had DGF were treated with a CI-free protocol consisting of antibody induction (basiliximab or thymoglobulin), sirolimus, mycophenolate mofetil, and prednisone. Serial biopsies were performed for persistent DGF. Patients were followed prospectively with the primary endpoints being patient and graft survival, biopsy-proven acute rejection, and sirolimus-related toxicity. RESULTS: Nineteen recipients were treated. Mean follow-up was 294 days. Actuarial 6- and 12-month patient survival was 100% and 100% and graft survival was 93% and 93%, respectively. The only graft loss was due to primary non-function (PNF). The incidence of AR was 16%. Mean serum creatinine at last follow-up was 1.6 mg/dL. Sirolimus-related toxicity included lymphocele (1), wound infection (2), thrombocytopenia (1). and interstitial pneumonitis (1). CONCLUSION: A CI-free protocol with antibody induction and sirolimus results in low rates of AR and PNF and excellent early patient and graft survival in patients with MDK and DGF. CI-free protocols may allow expansion of the kidney donor pool by encouraging utilization of MDK at high risk for DGF or CI-mediated nephrotoxicity.

RESUMEN / SUMMARY:  - The recent Kidney Disease Outcomes Quality Initiative (K/DOQI) classification of chronic kidney disease (CKD) includes transplant recipients. Although there are important differences between kidney transplant recipients (KTRs) and patients with native kidney disease, the inclusion of KTRs along with other CKD patients is an important step to improve long-term outcomes among transplant recipients. In this article we discuss the applicability of the K/DOQI classification of CKD to transplant recipients and the importance of premature patient death with graft function as a cause of graft loss. The implementation of a comprehensive program of CKD care beginning prior to transplantation and continuing after graft failure is discussed as a strategy to improve patient outcomes and specific areas of concern for KTRs are highlighted.  N.

RESUMEN / SUMMARY:  - A 37-yr-old man who had undergone renal transplantation for end-stage renal failure presented with a large right pelvic mass obstructing the transplanted kidney. Initially, this was diagnosed as an anaplastic tumor while he had been on immunosuppressive treatment for kidney allograft rejection after transplantation. Despite difficulties of classic histopathology to reveal the origin of his tumor, FISH analysis revealed the presence of chromosome 12p abnormalities, strongly indicative of a germ-cell tumor-more likely seminoma-with extragonadal presentation. Because of renal dysfunction, he was treated with carboplatin (dose adjusted according to renal clearance) and etoposide, and when he experienced a rather atypical progression with bone metastases, he was treated with single-agent paclitaxel, and died almost 13 mo after initial presentation. The case adds further to the existing small list of seminoma/GCTs developing in transplant recipients, points to the unusual presentation patterns and diagnostic histopathology challenges, and presents the difficulty in therapeutic options, as a result of frequent renal dysfunction and intercurrent immunosuppressive therapy. All of these issues together with an extensive literature review are discussed in detail.

RESUMEN / SUMMARY:  - Posttransplant erythrocytosis (PTE) is defined as a persistently elevated hematocrit to a level greater than 51% after renal transplantation. It occurs in 10% to 15% of graft recipients and usually develops 8 to 24 months after engraftment. Spontaneous remission of established PTE is observed in one fourth of the patients within 2 years from onset, whereas in the remaining three fourths it persists for several years, only to remit after loss of renal function from rejection. Predisposing factors include male gender, retention of native kidneys, smoking, transplant renal artery stenosis, adequate erythropoiesis prior to transplantation, and rejection-free course with well-functioning renal graft. Just as in other forms of erythrocytosis, a substantial number (approximately 60%) of patients with PTE experience malaise, headache, plethora, lethargy, and dizziness. Thromboembolic events occur in 10% to 30% of the cases; 1% to 2% eventually die of associated complications. Posttransplant erythrocytosis results from the combined trophic effect of multiple and interrelated erythropoietic factors. Among them, endogenous erythropoietin appears to play the central role. Persistent erythropoietin secretion from the diseased and chronically ischemic native kidneys does not conform to the normal feedback regulation, thereby establishing a form of “tertiary hypererythropoietinemia.” However, erythropoietin levels in most PTE patients still remain within the “normal range,” indicating that erythrocytosis finally ensues by the contributory action of additional growth factors on erythroid progenitors, such as angiotensin II, androgens, and insulin-like growth factor 1 (IGF-1). Inactivation of the renin-angiotensin system (RAS) by an angiotensin-converting enzyme (ACE) inhibitor, or an angiotensin II type 1 AT1 receptor blocker represents the most effective, safe, and well-tolerated therapeutic modality.  N.

RESUMEN / SUMMARY:  - GUIDELINES: A. Because renal transplantation can extend the duration and quality of life in elderly patients (age 60-70 years) with end-stage renal disease, transplantation should be considered in all patients, particularly if special programmes and preparations are applied. B. In elderly kidney transplant recipients, immunosuppression has to be adapted to avoid both rejections and adverse effects. C. Accurate diagnosis and aggressive treatment of cardiovascular disease in elderly recipients are recommended because of the high number of deaths with functioning grafts. D. The high risk of concomitant diseases, such as diabetes mellitus, bone disease and malignancies, needs special consideration.

RESUMEN / SUMMARY:  - Human polyomavirus type BK (BKV) associated nephritis (BKVAN) has recently emerged as an important cause of renal allograft dysfunction and failure. Early recognition of this entity as a cause of allograft dysfunction is extremely important since misdiagnosis can accelerate graft loss. We report a case of BKVAN that presented with symptoms related to cystitis, and review the risk factors, the diagnostic tools and the approach to treatment of BK virus associated allograft nephropathy.  N.

INSTITUCIÓN / INSTITUTION:  - Department of Surgery, The Medical School, University of Newcastle, Newcastle upon Tyne, UK.

RESUMEN / SUMMARY:  - Tubulitis is used by the Banff protocol as a major criterion to grade acute renal allograft rejection. This review integrates results from in vitro and in vivo studies to develop a chronological model to explain the development and functions of tubular inflammation during the rejection process. Proteoglycan-immobilized chemokines are the primary motivators for the vectorial recruitment of specific immune cell populations from the blood, through the endothelium and interstitial tissues to the renal tubules. After penetration of the basement membrane, T cells encounter TGF-beta that can induce expression of the alphaEbeta7 integrin on proliferating cells. This allows adhesion to E-cadherin on the baso-lateral surfaces of tubular epithelial cells and provides an explanation for the epithelial-specific cytotoxicity observed during acute rejection. Tubular epithelium is also a rich source of IL-15 that can stimulate IL-15 receptor-expressing intratubular CD8+ T cells. This anti-apoptotic microenvironment may explain the long-term persistence of cycling T cells within intact tubules after episodes of acute rejection. These memory-like T cells may have local immunoregulatory properties, including the production of additional TGF-beta, but could also modify normal tubular homeostasis resulting in epithelial to mesenchymal transdifferentiation, tubulointerstitial fibrosis and, ultimately, graft failure.  N.

AUTORES / AUTHORS:  - Rodd C

INSTITUCIÓN / INSTITUTION:  - Montreal Children’s Hospital, Quebec, Canada. crodd@po-box.mcgill.ca

RESUMEN / SUMMARY:  - Bisphosphonates are an old class of compounds. They were used in the 1930s as antiscaling and anticorrosion agents in washing powders and water to prevent the deposition of calcium crystals. Those basic functions were later utilized in an attempt to prevent ectopic calcifications in humans. The early studies demonstrated that bisphosphonates had a strong affinity for bone. That property was first exploited when the compounds were used for “bone scans.” Currently, the drugs are used for treatment of hypercalcemic conditions, abnormal bone remodelling, Paget disease, malignancy, and osteoporosis. Bisphosphonates have several important toxicities: acute renal failure, worsening renal function, reduced bone mineralization, and osteomalacia. For those reasons and others, this class of drugs has not yet been approved for use in children or in patients with severe renal insufficiency. The present review covers several aspects of bisphosphonates: molecular structure, routes of administration, pharmacology, mechanisms of action, toxicities, and exceptional uses in children with renal disease.  N.

AUTORES / AUTHORS:  - Samsonov D; Briscoe DM

INSTITUCIÓN / INSTITUTION:  - Division of Nephrology, Department of Medicine, Children’s Hospital and Harvard Medical School, Boston, Massachusetts 02115, USA.

RESUMEN / SUMMARY:  - In this review, we discuss current and future issues in the management of pediatric renal transplant recipients, including the optimization of long-term graft function and the minimization of complications caused by immunosuppression. Long-term management involves not only the monitoring of graft function but also the identification of patients at risk for the development of complications. The identification of patients with immunoreactive or immunoregulatory responses can be performed molecular monitoring of the immune response. Also, the use of frequent surveillance kidney biopsies, surrogate markers of chronic rejection, and glomerular filtration rate will be a part of future management. Identifying high-risk patients enables the physician to optimize immunosuppression to limit acute rejection. Short-and long-term management of pediatric transplant patients also includes adequate monitoring of growth and the monitoring for post-transplant lymphoproliferative disease. Ongoing clinical trials are underway that focus on these novel approaches in caring for pediatric transplant recipients.  N. Ref:: 41

RESUMEN / SUMMARY:  - The immunosuppressive benefits of cyclosporine and tacrolimus in short-term and medium-term renal allograft survival are well documented. It is becoming increasingly clear that the basis of this immunosuppression, the inhibition of calcineurin, may be linked with nephrotoxicity, hypertension, hyperlipidemia, and new-onset diabetes mellitus, side effects that may lead to CRAD, death due to CVD, and late renal allograft loss. This clinical picture presents a clear need for new strategies that produce adequate immunosuppression to prevent acute rejection while simultaneously reducing the side effects associated with CNI-related therapies. Sirolimus combined with cyclosporine and tacrolimus has demonstrated an ability to reduce incidences of early acute rejection and, used as base therapy, has provided protection against acute rejection equivalent to that of cyclosporine, without the consequent nephrotoxicity associated with CNIs. In preliminary results from an ongoing clinical trial, sirolimus has been used to eliminate cyclosporine during maintenance immunosuppression, with subsequent improvements in measures of blood pressure and renal function. In addition, the antiproliferative properties of sirolimus and its ability to prevent graft vascular disease in animal studies make sirolimus a promising agent to decrease incidences of CRAD and improve long-term renal allograft survival. These findings point to a clear need to further explore both the efficacy of sirolimus immunotherapy and its long-term effects.  N. Ref:: 126

RESUMEN / SUMMARY:  - Renal transplantation has been a usual medical practice in developed countries for several decades. A large number of studies report the excellent results obtained with such a practice. The survival of the graft, although able to be improved, is excellent and gives a great deal of hope to patients with renal insufficiency. The high level of investigation into immunosuppressor drugs offers, almost continuously, more efficient and better tolerated products. Paradoxically, the usual problems of patients with a renal transplant are not immunological but cardiovascular. Elevated serum cholesterol levels, obesity, diabetes and other cardiovascular risk factors (CVRFs) are usual in these patients, arterial hypertension (AHT) being the most frequent. Nephrologists are increasingly using ambulatory blood pressure monitoring (ABPM) on a daily basis. In the last 10 years, we have obtained highly valuable and interesting results with this technique which have allowed us to study and understand with greater precision the relationship of AHT to the kidney. Here we analyse and review the most relevant aspects of ABPM in the different stages of kidney disease, with special emphasis on renal transplantation.  N. Ref:: 40

INSTITUCIÓN / INSTITUTION:  - Department of Pathology, Johns Hopkins Medical Institutions, Baltimore, MD 21209, USA.

RESUMEN / SUMMARY:  - Disseminated acanthamebiasis is a rare disease that occurs predominantly in patients with human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome but also in immunosuppressed transplant recipients. Few reports have focused on non-HIV-infected patients, in whom the disease is more likely to go unsuspected and undiagnosed before death. We describe a renal transplant recipient with Acanthamoeba infection and review the literature. The patient presented with osteomyelitis and widespread cutaneous lesions. No causative organism was identified before death, despite multiple biopsies with detailed histological analysis and culture. Disseminated Acanthamoeba infection was diagnosed after death, when cysts were observed in histological examination of sections of skin from autopsy, and trophozoites were found in retrospectively reviewed skin biopsy and surgical bone specimens. In any immunosuppressed patient, skin and/or bone lesions that fail to show improvement with broad-spectrum antibiotic therapy should raise the suspicion for disseminated acanthamebiasis. Early recognition and treatment may improve clinical outcomes.  N. Ref:: 32

INSTITUCIÓN / INSTITUTION:  - Department of Clinical Pathology, Jikei University, Kashiwa Hospital, Japan.

RESUMEN / SUMMARY:  - We histologically evaluated protocol biopsy specimens of renal allografts obtained in the early period and 1 year after transplantation. The patients were divided into those with at least one history of acute rejection (AR group) and no history of rejection (NAR group), and the histopathological features in the two groups were compared. A total of 45 early protocol biopsy specimens were obtained from 40 patients, and 31 1-year biopsy specimens were obtained from 30 patients. Acute rejection (AR) or borderline change was observed in the early protocol biopsy specimens from 19 (45.2%) cases. AR or borderline change was observed in 12 of 19 (63.2%) in the AR group, and in 7/26 cases (26.9%) in the NAR group. The incidence of AR or borderline change in the AR group was higher than in the NAR group. Toxic tubulopathy was found in the early protocol biopsy in 16 cases (35.6%). The 1-year biopsies tended to reveal more complicated findings. Chronic rejection (CR) was seen in 8/16 cases (50.0%) in the AR group, and it was more frequent than NAR group (two cases, 13.3%). In conclusion, the incidences of both AR and CR were higher in the cases with a previous episode of AR. The early protocol biopsy was useful in screening for subclinical AR and toxic tubulopathy. The 1-year biopsy was useful for evaluating various types of chronic graft damage. We expect that adequate treatment based on protocol biopsy findings in each patient will lead to better graft survival.

RESUMEN / SUMMARY:  - PURPOSE OF REVIEW: The purpose of this review is to summarize recent advances within the area of genetic polymorphisms with a specific emphasis on renal transplantation, and to discuss the potential clinical applications. RECENT FINDINGS: Due to recent advances in molecular techniques, there has been an abundance of publications describing genetic variability in molecules relevant to transplant outcome. Many studies are now demonstrating associations between polymorphisms in these candidate genes and outcomes in organ transplantation. SUMMARY: These studies emphasize the potential role of genetic variability in transplantation, and provide the rationale for large prospective studies to clearly define the potential benefits of genotyping in the risk stratification of transplant recipients.  N.

RESUMEN / SUMMARY:  - While the early results of renal transplantation have improved in the last years, but the long-term allograft survival have not improved to the same extent. The major cause of these graft losses is chronic allograft dysfunction (CAD). The pathogenesis of CAD is complex and results from a interaction of immune and nonimmune factors. Between these non-immunological related factors there are two cardiovascular risk factors, hypertension and especially hyperlipidemia, that have been implicated in the development and progression of CAD. Lipid profile abnormalities are very prevalent in renal transplant patients. In last years several authors have reported an association between different lipid profile alterations and CAD. We conducted an observational study in our group to determine the relationship between different lipid disturbances and CAD. The hypertriglyceridemia and the Lp(a)>30 mg/dL before and after transplantation were, between the lipid abnormalities, the two independent risk factors for CAD in a multivarite analysis.  N.

RESUMEN / SUMMARY:  - BACKGROUND: B19 virus infection with persistent anaemia has been reported in organ transplant recipients. Detection of B19 virus DNA in serum is the best direct marker of active infection. OBJECTIVE: The present study evaluated the incidence and clinical role of active B19 virus infection in renal transplant recipients presenting with anaemia. STUDY DESIGN: Forty-eight such recipients were investigated by nested PCR on serum samples. The controls were 21 recipients without anaemia. Active HCMV infection was also investigated as a marker of high immunosuppression. RESULTS AND CONCLUSIONS: In 11/48 (23%) patients B19 virus DNA was demonstrated in serum versus only 1/21 (5%) of the controls. Ten of these 11 patients had already been seropositive at transplantation and active infection occurred in eight of them during the first 3 months after transplantation. The remaining patient experienced a primary infection 9 months after transplantation. Eight (73%) of these 11 patients displayed a concomitant HCMV infection and four (36%) showed increasing serum creatinine levels but none developed glomerulopathy; 3/11 (27%) recovered spontaneously from anaemia whereas 8/11 (73%) needed therapy. In conclusion, the relatively high occurrence (23%) of B19 virus infection in patients presenting with anaemia, suggests that it should be considered in the differential diagnosis of persistent anaemia in renal transplant recipients. Presence of the viral DNA should be assessed early from transplantation and the viral load should be monitored to follow persistent infection and better understand the relation between active infection and occurrence of anaemia, and to assess the efficacy of IVIG therapy and/or immunosuppression reduction in clearing the virus.  N.

RESUMEN / SUMMARY:  - Intravenous immunoglobulin preparations (IVIG) are known to be effective in the treatment of various autoimmune and inflammatory disorders into their immunomodulatory, immunoregulatory, and anti-inflammatory properties. Recently, IVIG has been utilized in the management of highly sensitized patients awaiting renal transplantation. The mechanisms of suppression of panel reactive antibodies (PRA) in patients awaiting transplantation are currently under investigation and appear to be related to anti-idiotypic antibodies present in IVIG preparations. In this review, the various immunomodulatory mechanisms attributable to IVIG and their efficacy in reducing PRAs will be described. In addition, the use of IVIG in solid organ transplant recipients will be reviewed. The adverse events, safety considerations, and economic impact of IVIG protocols for patients awaiting solid organ transplantation will be discussed.  N. Ref:: 67

RESUMEN / SUMMARY:  - BACKGROUND: Because of concerns of increased risk of graft loss with recurrent disease, living donor (LD) transplantation in children with focal segmental glomerulosclerosis (FSGS) has been controversial. METHODS: The North American Pediatric Renal Transplant Cooperative Study (NAPRTCS) database from January 1987 to January 2000 was examined to determine differences in demographics, treatment, and outcomes in children with FSGS compared with other renal diseases. RESULTS: Data on 6484 children, 752 (11.6%) with FSGS, demonstrated that FSGS patients were more likely to be older and black, and were less likely to receive either pre-emptive or LD transplant (P < 0.001). No differences existed in human lymphocyte antigen (HLA) matching or immunosuppression regimens. Acute tubular necrosis occurred in more FSGS patients following LD (11.8 vs. 4.6%) or cadaveric (CD; 27.9 vs. 16.3%) transplants (P < 0.001). Graft survival was worse for LD FSGS patients (5 years 69%) compared with no FSGS (82%, P < 0.001) and was not significantly different than CD graft survival in the FSGS (60%) and No FSGS groups (67%). The LD to CD ratios of relative risk of graft failure were higher in FSGS patients (test for interaction, P = 0.01). Recurrence of original disease was the only cause of graft failure that differed between groups (P < 0.001). A greater percentage of LD FSGS graft failures was attributed to recurrence (P = 0.06). CONCLUSIONS: The impact of FSGS on graft survival in children is greatest in LD transplants, resulting in loss of expected LD graft survival advantage. The rationale for LD grafts in children with FSGS should be based on factors other than better outcomes typically associated with LD transplantation.

RESUMEN / SUMMARY:  - The complement system of components and receptors is one of the earliest forms of defence. Excessive or inappropriate activation can result in tissue damage, classically illustrated in immune-mediated nephritis. In addition, complement forms a bridge between innate and adaptive immunity, helping to prepare and focus T and B lymphocyte responses. More recent research in renal allograft models has shown that complement-inhibited and complement-deficient animals have reduced inflammatory injury and lowered antidonor immune responses. Furthermore, it is known that the transplanted kidney is a significant site of local synthesis of C3, although until recently the relative contribution of locally produced C3 to transplant injury was unknown. Current evidence indicates that defective local synthesis of C3 both reduces tissue injury and lowers the antidonor T cell response, substantially increasing graft survival. Among various possible explanations to account for these findings, the data favours a direct effect of complement on alloreactive T cell stimulation. Study of complement gene regulation by common immunosuppressive agents suggests that they do not influence local complement synthesis. Alternative approaches are therefore required to control the local effect of complement in the extravascular tissue compartment of the graft.  N. Ref:: 88

RESUMEN / SUMMARY:  - This study prospectively compared immunoprophylaxis with a single intraoperative dose (2 mg/kg) of monoclonal interleukin-2 receptor (IL-2R) antibody vs. noninduction in kidney transplant recipients treated with tacrolimus (FK 506), mycophenolate mofetil (MMF) and a prednisone-based immunosuppression regimen. One hundred recipients of first-kidney transplant were enrolled into the study to receive either anti-IL-2R monoclonal antibody, daclizumab (2 mg/kg intraoperatively, limited anti-IL-2R) or no induction (control). Each patient also received oral tacrolimus (dosed to target trough level 10-15 ng/mL), MMF (500 mg bid) and prednisone. The primary efficacy end-point was the incidence of biopsy proven acute rejection during the first 6 months post-transplant. The patients were also followed for 12-month graft function, and graft and patient survival rates. Other than the donor’s age being significantly lower in the control group, both groups were comparable with respect to age, weight, gender, race, human leukocyte antigen (HLA)-DR mismatch, panel reactive antibody (%PRA), cold ischemic time, cytomegalovirus (CMV) status, causes of renal failure, and duration and modes of renal replacement therapy (RRT). During the first 6 months, episodes of first biopsy confirmed acute rejection was 3/50 (6%) in the limited anti-IL-2R group and 8/50 (16%) in the controls (p < 0.05). Twelve-month patient 100/98 (%) and graft survival 100/96 (%) were not statistically different. The group receiving limited anti-IL-2R did not have any adverse reactions. Our study demonstrates that a limited (single) 2 mg/kg immunoprophylaxis dose with monoclonal IL-2R antibody (daclizumab) when combined with tacrolimus/MMF/steroid allows significant reduction in early renal allograft rejection to the single digit level. The therapy with anti-IL-2R antibody is simple and is well tolerated.

RESUMEN / SUMMARY:  - Major advances in immunosuppression and reductions in the rates of acute rejection have led to increasing graft and patient survival rates during the past two decades. Chronic dysfunction of the renal allograft, however, remains a major clinical problem and probably represents the end result of the complex interplay between donor and recipient factors, immunologic injury, nonimmunologic insults, and drug-induced nephrotoxicity. Optimal function of the renal allograft is obtained by maintaining a balance between underimmunosuppression and acute rejection and overimmunosuppression and drug-induced toxicities. To minimize side effects while maintaining efficacy, immunosuppressive drugs are commonly used as combination therapy. Pharmacokinetic and pharmacodynamic interactions between these agents can affect graft survival and function. The evidence supporting the role of therapeutic drug monitoring as applied to commonly used immunosuppressants in modern transplantation is presented here, and the increasing role of therapeutic drug monitoring in the optimization of graft and patient survival rates in the modern era of renal transplantation is discussed.  N.

TÍTULO / TITLE:  - Safety and efficacy of TOR inhibitors in pediatric renal transplant recipients.

RESUMEN / SUMMARY:  - Information about the pharmacokinetics, safety, and efficacy of target of rapamycin (TOR) inhibitors, such as sirolimus and everolimus, in pediatric renal transplant recipients is limited. In an ascending single-dose pharmacokinetic study of sirolimus in pediatric dialysis patients, no clinically significant association was observed between patient age and absorption of sirolimus from the gastrointestinal tract. However, young pediatric patients (5 to 11 years of age) exhibited significantly greater apparent oral clearances, suggesting that pediatric patients require slightly higher doses than do adults when adjusted for body weight or surface area. Similarly, in studies performed in pediatric renal transplant recipients, the half-life of sirolimus was shorter and the clearance was greater in younger patients. On the other hand, in single-dose pharmacokinetic studies of everolimus, the apparent clearance was reduced in pediatric renal transplant recipients compared with clearance in adults. This reduced clearance was attributed to a smaller apparent volume of distribution in pediatric patients, rather than to a difference in terminal half-life. This suggested that, although the adult 12-hour dosing interval was appropriate for pediatric patients, they would require reduced dosing based on body size compared with adults. In a large trial (N = 719) of sirolimus versus azathioprine in combination with cyclosporine microemulsion and prednisone, 6 pediatric patients (13 to 18 years of age) received sirolimus at 2 mg/d, 3 received sirolimus at 5 mg/d, and 3 received azathioprine. Seven of the nine patients who received sirolimus experienced no rejection episodes. Six infectious episodes occurred in the 6 patients receiving sirolimus at 2 mg/d, 10 episodes occurred in the 3 patients receiving sirolimus at 5 mg/d, and 8 episodes occurred in the 3 patients receiving azathioprine. At 6 months after transplantation, renal function was similar in all 3 groups, although there was a statistically nonsignificant increase in the group receiving sirolimus at 5 mg/d. The mean cholesterol and triglyceride levels were generally comparable in all 3 groups. TOR inhibitors are promising agents for the prevention of graft rejection in pediatric renal transplant recipients, but more pharmacokinetic data are required to assess the optimal dosing regimens in this population. In addition, further data are needed on the efficacy and safety of TOR inhibitors in combination with other agents in pediatric transplantation recipients to best assess the role of TOR inhibition in corticosteroid and/or calcineurin inhibitor-sparing regimens.  N.

RESUMEN / SUMMARY:  - Digoxin toxicity is a major public health issue in the United States. Often this is due to drug interactions, and renal transplant recipients are at particularly high risk for drug-drug interactions. We present cases of 2 renal transplant recipients who received itraconazole and digoxin concomitantly and experienced digoxin toxicity. We have also reviewed the relevant literature to elicit the mechanisms, signs, and symptoms of digoxin toxicity in the presence of itraconazole. When clinicians know the potential drug-drug interactions that may lead to digoxin toxicity, the mechanisms of interaction, the signs and symptoms of digoxin toxicity, and appropriate monitoring, digoxin toxicity is largely preventable.  N.

RESUMEN / SUMMARY:  - A 45-year-old man underwent renal transplant for end-stage renal disease complicating systemic lupus erythematosis. Within 24 hours of initiating Pneumocystis carinii pneumonia (PCP) prophylaxis with trimethoprim-sulfamethoxazole (TMP-SMX) he developed fever and confusion. Cerebrospinal fluid examination revealed a pleocytosis but cultures were negative. The patient improved within three days after cessation of the TMP-SMX but symptoms recurred rapidly upon drug rechallenge. Drug-induced aseptic meningitis is an uncommon but well described clinical entity. This is the first case described in a patient following renal transplantation. The literature is reviewed and the clinical features, diagnostic challenges and possible mechanisms of TMP-SMX-induced aseptic meningitis are discussed. This problem may be more common in the transplant population than is recognized given the difficulty of diagnosis combined with the widespread use of TMP-SMX as PCP prophylaxis.  N. Ref:: 20

RESUMEN / SUMMARY:  - Multiple studies during the past decades have identified chronic liver disease as an important cause of morbidity and mortality in kidney transplant recipients. It has been reported that up to 25% of patients will have some degree of abnormal liver functions during the immediate posttransplant period. In these patients, liver failure has been implicated as the cause of death in approximately 30% of the long-term survivors. While infections from hepatitis virus remain the main cause of ongoing liver damage, many other opportunistic infections with various potential to alter liver function have also been identified. In addition, posttransplant patients are also exposed to hepatotoxic adverse effects of many pharmacotherapeutics including immunosuppressive and nonimmunosuppressive agents. Since there are numerous reports dealing with classic viral hepatitis after kidney transplantation, this review primarily focuses on post-kidney transplant liver diseases which are not due to classic hepatitis viruses.  N.

RESUMEN / SUMMARY:  - Even though significant progress has been achieved in the management of patients with glycogen storage disease type I, hepatic (mainly adenomas) and renal (proteinuria, renal failure) complications may still develop. Orthotopic liver transplantation has been reported in less than 20 patients, and, in most cases, its indications were multiple hepatic adenomas, sometimes combined with poor metabolic control and/or growth retardation. Even though short-term outcome seems to be favourable, long-term complications have been reported in several cases. Thus it appears that improved metabolic control has to be attempted before performing liver transplantation in such patients. As for renal transplantation, it has been performed in patients with terminal renal failure. It is hoped that improving long-term metabolic control will prevent renal involvement from evolving to terminal renal failure. Finally, combined liver and kidney transplantation may be indicated in a few patients. CONCLUSION: organ (liver/kidney) transplantation in glycogen storage disease type I may be advantageous when long-term metabolic control has been attempted. Nevertheless, post-transplantat long-term complications may still develop.  N. Ref:: 24

TÍTULO / TITLE:  - New strategies to reduce nephrotoxicity.

REVISTA / JOURNAL:  - Transplantation 2001 Dec 27;72(12 Suppl):S99-104.

AUTORES / AUTHORS:  - Kreis H

RESUMEN / SUMMARY:  - Since the introduction of cyclosporine, CNIs have formed the basis of immunosuppressive therapy in renal transplantation. The propensity of these agents to ultimately damage the very organs they were intended to protect was always recognized, but largely ignored due to their impressive ability to improve short-term outcomes. With the availability of equally powerful new immunosuppressive agents devoid of major nephrotoxicity, the irony of this situation has become all too apparent, and investigators are beginning to reevaluate the role of CNIs in renal transplantation. In this paper, we looked at strategies using MMF or sirolimus to reduce, withdraw, or replace CNIs in renal transplantation. Although MMF has proved effective in combination with CNIs, particularly in reducing acute rejection rates, its use as base therapy to allow CNI therapy to be withdrawn or eliminated is questionable. On the basis of initial trials, sirolimus holds promise for use as base therapy. To date, it is probably the only agent used in renal transplantation that provides immunosuppression comparable to cyclosporine or tacrolimus, which may someday allow sirolimus to replace. CNIs or allow early withdrawal of CNI therapy. Further study is needed to better clarify the role of sirolimus in improving long-term renal transplantation outcomes.  N. Ref:: 61

RESUMEN / SUMMARY:  - Viral infections are a leading cause of posttransplantation morbidity and mortality. A number of recent developments have altered our understanding and management of these disorders. The pathogenetic roles of several viruses, including human herpesviruses 6 and 8, have been newly established. Molecular-based diagnostic tests now make more rapid diagnosis possible. The licensing of new potent antiviral agents offers a wider choice of drugs for viral prophylaxis and treatment. The use of more potent immunosuppressive agents is responsible in part for the increasing incidence of some viral infections, but this varies among drugs, and individual viruses differ in their sensitivity to immunosuppressive agents. This review summarizes the natural history, diagnosis, prevention, and treatment of many common viral infections after renal transplantation.  N. Ref:: 103

RESUMEN / SUMMARY:  - The elderly dialysis patient presents several challenges to the nephrologist. Concurrent illnesses may complicate management, disabilities may interfere with mobility, hearing, and vision, and depression and mental incompetence may be present. For these reasons the physician and health care team should adopt a broad treatment plan, using expert help if needed in managing the patient and involving family members, clergy, and friends. While lifestyle changes are inevitable for the elderly with initiation of dialysis, satisfactory outcomes are possible. In the event of overwhelming illness and the patient’s perception of the futility of continuation of dialysis, cessation of dialysis must be approached in a humane, considerate, and compassionate manner.  N.

RESUMEN / SUMMARY:  - Renal transplant artery stenosis is a relatively frequent complication after transplantation, with an incidence of up to 23% being reported. The gold standard for the diagnosis still remains renal arteriography. Several imaging techniques are available to confirm the diagnosis (duplex-Doppler, nuclear magnetic resonance, spiral computerized tomography), and their use depends, in part, on the centre’s experience. The treatment can either be conservative (providing graft perfusion is not jeopardized) or by revascularization (surgical or percutaneous transluminal angioplasty). There are several unresolved questions concerning revascularization of the graft: whether and when to intervene? Is the stenosis progressive in the long term? Is hypertension alone an indication for angioplasty? How do we assess the haemodynamic significance of the stenosis? What is a significant stenosis-50, 60, 80 or 90%? Is stenosis ‘good’ for something? In Slovenia, since 1990, all renal transplant recipients are screened regularly for the presence of stenosis by duplex-Doppler (performed by nephrologists), and also in cases of deterioration of graft function or hypertension. In the majority of patients with a diagnosed stenosis, the latter was found to be stable over time (assessed by regular Doppler, graft function and hypertension control). In some patients, spontaneous regression of the stenosis was observed. Frequent Doppler assessment of these patients helps to be more conservative with angioplasty and angiography. Deterioration of graft function (with stenosis diagnosed by Doppler) is the main indication for angiography (and angioplasty). Better definition of significant stenosis and randomized studies comparing conservative treatment vs angioplasty are warranted. Duplex-Doppler seems to be the ideal screening and follow-up test.  N.

RESUMEN / SUMMARY:  - Renal transplantation has become the preferred means of treating end-stage renal disease. Episodes of allograft rejection have become the exception rather than the rule. The development of real-time ultrasound-guided allograft biopsy and adoption of the Banff criteria for histologic evaluation permit safe,accurate monitoring of graft histology. New immunosuppressive agents have drastically reduced the number of episodes of both primary and refractory rejection. Novel biologic agents in the form of monoclonal antibodies and soluble receptor hybrid molecules may serve to reduce the required doses of toxic chemical immunosuppressants and provide more specific immune suppression directed at those elements of the immune system involved in rejection of a given allograft. Development of assays to identify patients who demonstrate donor antigen-specific hyporeactivity is now feasible. Hopefully, these assays will serve as a guide for the reduction and possible removal of immunosuppressive agents from stable renal allograft recipients.  N. Ref:: 81

INSTITUCIÓN / INSTITUTION:  - Froedert Memorial Hospital, Medical College of Wisconsin, Milwaukee, WI 53226, USA. hari@mcw.edu

RESUMEN / SUMMARY:  - With improvements in short-term kidney graft survival, focus has shifted towards long-term survival. There has also been a substantial improvement in long-term survival as measured by kidney half-life. Long-term graft failure is secondary to chronic allograft nephropathy (CAN), recurrent disease, and death with a functioning graft. CAN is secondary to a combination of chronic rejection, chronic cyclosporine toxicity, and/or donor kidney disease. Risk factors for chronic rejection have been attributed to both immunological and nonimmunological causes. With a marked reduction in acute rejection rates-an important risk factor for CAN-there is a substantial improvement in kidney half-life. There are still nonimmunological factors, such as donor age, that adversely affect long-term graft survival. In addition, African-American recipients continue to have a shorter graft half-life. Recurrent disease is becoming an important cause of late graft failure. Despite the introduction of various potent immunosuppressive agents, there has been little or no impact on the prevalence as well as progression of recurrent diasease. With the reduction of acute rejection rates and improved short- and long-term graft survival, further improvements of long-term graft survival will be an important focus in the 21st century.  N.

INSTITUCIÓN / INSTITUTION:  - Department of Nephrology, Dialysis and Transplantation, St Bortolo Hospital, Vicenza, Italy. cronco@goldnet.it

RESUMEN / SUMMARY:  - Renal replacement therapy (RRT) has evolved from the concept that we need to treat the dysfunction of a single organ (the kidney). As intensive care units have become more and more complex, it has become clear that the majority of patients with acute renal failure often have dysfunction of several other organs. In order to facilitate single organ support in this setting, continuous renal replacement therapy (CRRT) techniques have been developed. However, CRRT has opened the door to the concept that targeting renal support as the only goal of extracorporeal blood purification may be a simplistic view of our therapeutic aims. In this article we argue that it is now time to move from the simple goal of achieving adequate renal support. The proper goal of extracorporeal blood purification in ICU should be multi-organ support therapy (MOST). We explain why MOST represents the most logical future conceptual and practical evolution of CRRT and illustrates the biological rationale, supplying animal and clinical evidence that confirms the need to move rapidly in this direction theoretically, practically and technologically.  N.

RESUMEN / SUMMARY:  - A systematic re-analysis of published cases was performed to better define the role of plasmapheresis in the treatment recurrent focal segmental glomerulosclerosis after renal transplantation. Forty-four cases were identified, of which 32 responded to apheresis. The median number of treatments to response was 9. There was no difference between responders and nonresponders in the total number of treatments performed. The presence of sclerosis on biopsy predicted treatment failure. Relapse after first successful treatment was reported in 10 cases. The median number of treatments received was less and the time from diagnosis to first treatment was greater for patients who relapsed than for patients in whom relapse was not reported, but the differences were not statistically significant. On the basis of this analysis, we recommend early treatment after diagnosis with a regimen of three daily plasmapheresis treatments followed by 6 treatments on an every other day basis.  N.

RESUMEN / SUMMARY:  - PURPOSE OF REVIEW: Hypertension is very common in renal transplant recipients and is a significant risk factor for mortality from cardiovascular diseases and for development of graft dysfunction. RECENT FINDINGS: Recent guidelines for the treatment of hypertension (Joint National Committee on Prevention, Detection, and Treatment of High Blood Pressure VI Report and World Health Organization Guidelines) do not directly address post-transplant hypertension. Specific recommendations for the drug treatment of hypertension in renal allograft recipients have not been given in the Clinical Practice Guidelines of the American Society of Transplantation or those of the European Renal Association. SUMMARY: The present paper summarizes some important aspects of post-transplant hypertension and discusses potential treatment strategies aimed at reducing blood pressure and thus improving patient and allograft survival.  N.

RESUMEN / SUMMARY:  - Of the several causes of nondiarrheal hemolytic uremic syndrome (HUS), infection with Streptococcus pneumoniae is infrequent, but important, because of its unique pathogenesis. A comprehensive literature review found 37 well-documented cases of S pneumoniae-associated HUS (SP-HUS), only 2 of which progressed to end-stage renal disease (ESRD). We report the third such child, and the first to receive a renal transplant following SP-HUS. Her course illustrates several unique characteristics of SP-HUS common to previous patients reported in the literature, including a greater duration of oligoanuria compared with cases not progressing to ESRD, the significant adverse effect of unwashed blood products, and a possible influence of female gender on outcome. Clinicians caring for children with SP-HUS should be aware of these differences and modify therapy appropriately to avoid known risk factors for poor outcome, specifically the use of unwashed blood products.  N.

RESUMEN / SUMMARY:  - Recent epidemiologic studies show that iron deficiency occurs in the vast majority of patients with chronic kidney disease (CKD). In patients with CKD, increased iron losses and, to a lesser extent, poor oral absorption, can lead to iron-deficiency anemia. Correction of iron-deficiency anemia is preferable by the oral route, however, data on oral iron use are limited in this population. In CKD patients, parenteral iron administered with recombinant human erythropoietin (rHuEpo), is the best potential option for the correction of anemia. Nondextran iron preparations are preferable because of a reduced incidence of serious adverse events. Parenteral iron in CKD patients may not be entirely innocuous and, although commonly used, have not received Food and Drug Administration approval for use in this patient population. Exposure to intravenous (IV) iron may lead to oxidative stress, renal injury, infection, cardiovascular disease, and osteomalacia. Studies are needed to confirm the existence and magnitude of these complications. The current data suggest that the overall risk-benefit ratio favors use of IV iron when compared with untreated or partially treated iron-deficiency anemia.  N. Ref:: 55

RESUMEN / SUMMARY:  - BACKGROUND: Chronic graft nephropathy (CGN) remains the leading cause of renal allograft loss after the first year following transplantation. Histologically it is characterized by glomerulosclerosis, intimal hyperplasia and interstitial fibrosis. The pathogenesis is unclear, but is likely to involve both immunological and non-immunological factors. Despite improvements in short-term graft survival rates, new immunosuppressive regimens have made no impact on CGN. METHODS: A review of the current literature on renal transplantation, novel immunosuppression regimens and advances in the molecular pathogenesis of renal allograft fibrosis was performed. RESULTS AND CONCLUSION: Recent advances in understanding of the underlying molecular mechanisms involved suggest autocrine secretion of cytokines and growth factors, especially transforming growth factor beta, are associated with a change in fibroblast phenotype leading to the deposition of extracellular matrix. Repeated insults trigger upregulation of the tissue inhibitors of matrix metalloproteinases, favouring accumulation of extracellular matrix. To date, no drug has proved effective in inhibiting or reducing allograft fibrosis. The deleterious consequences of chronic immunosuppression on the development of such fibrosis are now recognized; newer immunosuppressive drugs, including rapamycin and mycophenolate mofetil, reduce profibrotic gene expression in both experimental and clinical settings, and offer potential strategies for prolonging allograft survival.  N.

RESUMEN / SUMMARY:  - Tissue injury is probably the central feature leading to CRAD, whether that injury is produced by immunological or nonimmunological factors. Tissue injury may expose cryptic antigens that, in an allogeneic situation, stimulate immune responses that further increase tissue damage. With acute rejection the immunological factor most strongly predictive of CRAD, HLA mismatches may facilitate rejection or otherwise lead to CRAD. However, clinical studies have not always demonstrated an increasing risk of CRAD with increased numbers of HLA mismatches. Antibodies produced against HLA or other donor-specific antigens may play a role in initiating the CRAD process or may occur secondary to tissue damage. Several human transplant studies have demonstrated an association between anti-HLA or anti-B cell antibodies and CRAD. In animal models of CRAD, antibodies are produced against antigens associated with glomerular and tubular basement membranes and mesangial cells, as well as antigens associated with vascular endothelial cells. The pathogenetic significance of these antibody responses is unclear at this time, but these responses may interfere with repair processes that follow tissue injury or otherwise facilitate mechanisms leading to CRAD. Whether similar antibody responses against components of basement membrane and mesangial cells occur in human renal transplant patients with CRAD is not yet known. The most effective way to prevent CRAD is to prevent tissue damage, especially immunity-related injury that involves maintaining appropriate immunosuppression. When using calcineurin inhibitors for immunosuppression, there is a risk of chronic calcineurin inhibitor-associated nephrotoxicity. Nonnephrotoxic immunosuppressive agents, such as sirolimus and mycophenolate mofetil, may be considered in therapeutic strategies designed to prevent acute rejection and to minimize renal tissue damage due to nephrotoxic drugs.  N.

RESUMEN / SUMMARY:  - Viral infections, particularly those involving HCMV, are an important complication of renal transplantation. Transplantation protocols and treatment regimens that increase HCMV infection and disease may promote the development of CRAD and impair long-term renal allograft survival. Investigators are beginning to illuminate the mechanisms by which HCMV infection may cause chronic rejection in general and transplant vascular sclerosis in particular. Migration and proliferation of SMCs within the intimal layer of blood vessels is an important component of transplant vascular sclerosis, and HCMV appears to facilitate both of these processes. Current management strategies for HCMV focus on prevention, either using a focal preemptive therapeutic approach or by administering antiviral therapies to all or at-risk patients.  N. Ref:: 74

RESUMEN / SUMMARY:  - We describe 2 male patients, a 49-year-old with psoriatic arthritis and impaired renal function and a 43-year-old renal transplant recipient, who both sustained a marked decline in glomerular filtration rate in conjunction with a selective inhibitor of cyclooxygenase-2 (COX-2), rofecoxib. In the second patient, acute renal failure necessitated hemodialysis. Both patients made an uneventful recovery. Our report lends further support to the assumption that COX-2 inhibitors, as a class, can be as nephrotoxic as their nonselective predecessors. Therefore, COX-2 inhibitors should be used with caution in renal transplant recipients and in patients with salt depletion and renal insufficiency.  N. Ref:: 15

INSTITUCIÓN / INSTITUTION:  - Department of Medicine, University of Texas Health Science Center at San Antonio, 78229, USA.

RESUMEN / SUMMARY:  - We present a case of living, related-donor kidney transplantation during the first trimester of pregnancy. The patient received mycophenolate mofetil (MMF), tacrolimus, and prednisone throughout the entire pregnancy. This is the first reported case of use of MMF during pregnancy. The mother did well, except for mild preeclampsia and mild renal insufficiency at term. The baby girl was born prematurely at week 353/7. The only possible teratogenic effects detected included hypoplastic nails and short fifth fingers. No chromosomal abnormalities were found. The child is growing and developing normally. Although we do not recommend the use of mycophenolate mofetil during pregnancy based on this experience, it is reassuring to know that a successful outcome can be expected in mothers treated with MMF during pregnancy.  N.

RESUMEN / SUMMARY:  - PURPOSE OF REVIEW: This review is on renal function in patients with spina bifida. Risk factors for renal injury as well specific issues concerning the treatment of chronic renal failure, renal replacement therapy and kidney transplantation are discussed. Relevant work published earlier than 2000 is also considered because of a lack of recent literature. RECENT FINDINGS: Data from adult and paediatric surveys show renal damage to be the single most prevalent cause of morbidity and mortality; even in children, 30-40% exhibit evidence of renal damage. Additional factors such as chronic infection and stone formation will then render the kidney more vulnerable to progressive loss of renal mass and subsequent chronic renal failure. As in other patients with renal insufficiency, the control of hypertension, preferably with angiotensin-converting enzyme inhibitors, and adequate nutrition are mainstays of nephrological care. The modality of dialysis in these patients is complicated by ventriculoperitoneal shunts or urinary stomata in peritoneal dialysis, or difficult vascular access in haemodialysis. Renal transplantation is now considered the optimal treatment for end-stage renal disease in all age groups. Although more prone to complications, recent data on patients with meningomyelocele or severely abnormal lower urinary tracts demonstrate excellent patient and graft outcomes.SUMMARY: The common goal in caring for these patients must be the prevention of progressive renal damage. However, once kidney failure has occurred, good and safe techniques for renal replacement therapy are available to bridge the time to transplantation, which is undoubtedly the best treatment for these patients.  N.

INSTITUCIÓN / INSTITUTION:  - Department of Surgery, University of Cincinnati Medical Center, Ohio 45267-0585, USA.

RESUMEN / SUMMARY:  - Ongoing improvements in immunosuppression and posttransplantation care have dramatically improved patient and graft outcomes after transplantation. The frequency of graft loss due to acute rejection has declined considerably as a result of the availability of a variety of more potent immunosuppressive agents and probably also because of refined clinical care and follow-up. Complications of long-term administration of corticosteroids (steroids) and calcineurin inhibitors, however, have become increasingly apparent as patients live longer with their transplant, and attention is shifting to long-term issues. Use of both steroids and calcineurin inhibitors is associated with metabolic toxicities such as hypertension, hyperlipidemia, diabetes, bone loss, and cataracts. These contribute to posttransplantation morbidity and may negatively affect patient and allograft survival. A variety of troublesome cosmetic side effects, such as hirsutism, gingival hyperplasia, alopecia, obesity, and cushingoid appearance, also are associated with these drugs. These effects can detract from patient self-esteem and compliance with the immunosuppressive regimen. In the past 2 decades, the introduction of second-generation immunosuppressive drugs, such as tacrolimus, mycophenolate mofetil, sirolimus, and anti-interleukin-2 receptor monoclonal antibodies, has provided some alternatives to classic immunosuppressant choices. Patients experiencing undesirable adverse events now can be converted to another immunosuppressive regimen that ultimately will improve graft and patient survival rates and improve quality of life after transplantation.  N.

RESUMEN / SUMMARY:  - To investigate the possibility that we have been underestimating the true incidence of acute rejection, we began to perform protocol biopsies after kidney transplantation. This analysis looks at the one-week biopsies. Between March 1 and October 1, 1999, 100 adult patients undergoing cadaveric kidney or kidney/pancreas transplantation, or living donor kidney transplantation, underwent 277 biopsies. We focused on the subset of biopsies in patients without delayed graft function (DGF) and with stable or improving renal function, who underwent a biopsy 8.2+/-2.6 d (range 3-18 d) after transplantation (n = 28). Six (21%) patients with no DGF and with stable or improving renal function had borderline histopathology, and 7 (25%) had acute tubulitis on the one-week biopsy. Of the 277 kidney biopsies, there was one (0.4%) serious hemorrhagic complication, in a patient receiving low molecular weight heparin; she ultimately recovered and has normal renal function. Her biopsy showed Banff 1B tubulitis. In patients with stable or improving renal allograft function early after transplantation, subclinical tubulitis may be present in a substantial number of patients. This suggests that the true incidence of rejection may be higher than is clinically appreciated.

RESUMEN / SUMMARY:  - With the success of organ transplantation, liver disease has emerged as an important cause of morbidity and mortality of renal transplant (RT) recipients. Numerous studies performed during the 1990s have shown that hepatitis C virus (HCV) infection is the leading cause of chronic liver disease among RT recipients. The transmission of HCV by renal transplantation of a kidney from an HCV-infected organ donor has been shown unequivocally. Liver biopsy is essential in the evaluation of liver disease of RT recipients, and histological studies have shown that HCV-related liver disease after renal transplantation is progressive. The outcome of HCV-related liver disease is probably more aggressive in RT recipients than immunocompetent individuals. Various factors can affect the progression of HCV in the RT population: coinfection with hepatitis B virus, time of HCV acquisition, type of immunosuppressive treatment, and concomitant alcohol abuse. The role of virological features of HCV remains unclear. The natural history of HCV infection after renal transplantation is under evaluation; however, recent surveys with long follow-ups have documented adverse effects of HCV infection on patient and graft survival in RT recipients. Use of renal grafts from HCV-infected donors in recipients with HCV infection does not appear to result in a greater burden of liver disease, at least for a short period. The association between HCV and de novo or recurrent glomerulonephritis after RT has been hypothesized and is an area of avid research. Reported studies do not support interferon (IFN) treatment for RT recipients with chronic hepatitis C because of the frequent occurrence of graft failure, and information on the use of other types of IFN or combined therapy (IFN plus ribavirin or amantadine) is not yet available in the RT population.  N.

INSTITUCIÓN / INSTITUTION:  - Department of Histopathology, Manchester Royal Infirmary, Manchester, United Kingdom.

RESUMEN / SUMMARY:  - BACKGROUND: Arteritis and tubulitis, the diagnostic features of acute renal allograft rejection, are typically focal lesions. To avoid under-diagnosis, the Banff ‘97 schema recommends the preparation of multiple slides, of which three should be stained with hematoxylin and eosin (H&E) and three with periodic acid-Schiff (PAS) or silver. In this study, we examine the validity of the Banff ‘97 recommendations and determine how widely these recommendations are applied. METHODS: We reviewed 52 consecutive renal transplant biopsy specimens showing both acute tubulointerstitial and vascular rejection. Arteritis was graded for each H&E slide, and tubulitis was graded for each H&E and PAS/silver. The handling of renal allograft biopsy specimens in the U.K. was determined by means of a questionnaire. RESULTS: When two, as opposed to three, H&E slides were examined, arteritis was missed in 11.4% of cases; when only one H&E slide was examined, arteritis was missed in 33.3% of cases. When only one, as opposed to three, PAS/silver slide was examined, tubulitis was under-graded in 33.3% of cases. In the U.K., 40% of laboratories stain at least three slides with H&E, and 42% stain at least three slides with PAS/silver. Only 30% of laboratories conform to all the Banff guidelines for slide preparation. CONCLUSIONS: There is likely to be significant under-diagnosis and under-grading of acute rejection if the Banff ‘97 guidelines for slide preparation are not implemented. Most laboratories in the U.K. do not conform to these guidelines.

INSTITUCIÓN / INSTITUTION:  - Adis International Limited, Auckland, New Zealand. demail@adis.co.nz

RESUMEN / SUMMARY:  - Extensive clinical use has confirmed that tacrolimus (Prograf) is a key option for immunosuppression after transplantation. In large, prospective, randomised, multicentre trials in adults and children receiving solid organ transplants, tacrolimus was at least as effective or provided better efficacy than cyclosporin microemulsion in terms of patient and graft survival, treatment failure rates and the incidence of biopsy-proven acute and corticosteroid-resistant rejection episodes. Notably, the lower incidence of rejection episodes after renal transplantation in tacrolimus recipients was reflected in improved cost effectiveness. In bone marrow transplant (BMT) recipients, the incidence of tacrolimus grade II-IV graft-versus-host disease was significantly lower with tacrolimus than cyclosporin treatment. Efficacy was maintained in renal and liver transplant recipients after total withdrawal of corticosteroid therapy from tacrolimus-based immunosuppression, with the incidence of acute rejection episodes at up to 2 years’ follow-up being similar with or without corticosteroids. Tacrolimus provided effective rescue therapy in transplant recipients with persistent acute or chronic allograft rejection or drug-related toxicity associated with cyclosporin treatment. Typically, conversion to tacrolimus reversed rejection episodes and/or improved the tolerability profile, particularly in terms of reduced hyperlipidaemia. In lung transplant recipients with obliterative bronchiolitis, conversion to tacrolimus reduced the decline in and/or improved lung function in terms of forced expiratory volume in 1 second. Tolerability issues may be a factor when choosing a calcineurin inhibitor. Cyclosporin tends to be associated with a higher incidence of significant hypertension, hyperlipidaemia, hirsutism, gingivitis and gum hyperplasia, whereas the incidence of some types of neurotoxicity, disturbances in glucose metabolism, diarrhoea, pruritus and alopecia may be higher with tacrolimus treatment. Renal function, as assessed by serum creatinine levels and glomerular filtration rates, was better in tacrolimus than cyclosporin recipients at up to 5 years’ follow-up. CONCLUSION: Recent well designed trials have consolidated the place of tacrolimus as an important choice for primary immunosuppression in solid organ transplantation and in BMT. Notably, in adults and children receiving transplants, tacrolimus-based primary immunosuppression was at least as effective or provided better efficacy than cyclosporin microemulsion treatment in terms of patient and graft survival, treatment failure and the incidence of acute and corticosteroid-resistant rejection episodes. The reduced incidence of rejection episodes in renal transplant recipients receiving tacrolimus translated into a better cost effectiveness relative to cyclosporin microemulsion treatment. The optimal immunosuppression regimen is ultimately dependent on balancing such factors as the efficacy of the individual drugs, their tolerability, potential for drug interactions and pharmacoeconomic issues.  N.

RESUMEN / SUMMARY:  - The clinical management of cytomegalovirus infection and disease in renal transplant recipients has recently been significantly improved with the availability of data on prophylaxis with oral ganciclovir and valacyclovir. In addition, significant progress in early diagnosis and the quantitation of viral load has been achieved. The influence of novel immunosuppressants on the clinical course of cytomegalovirus infection has been clarified to some extent by recent clinical data. The identification of risk factors for cytomegalovirus disease beyond seroconstellation and immunosuppression is an ongoing process that might lead to a more targeted use of antiviral agents, given the risk of ganciclovir resistance. The understanding of the effects of cytomegalovirus on long-term graft outcome still needs to be deepened in order to design cytomegalovirus-specific interventions to improve graft survival.  N.

RESUMEN / SUMMARY:  - Pediatric renal transplantation recipients have numerous risk factors for decreased bone mass, including the underlying renal disease, nutritional deficits, decreased physical activity, inflammation and exposure to steroid therapy. The assessment of bone mineralization in children following renal transplantation is fraught with difficulty. Dual energy x-ray absorptiometry (DXA) is the most commonly employed tool to assess bone mineralization. However, DXA has important limitations in children and in individuals with renal disease. This brief review will examine the expected gains in bone size and bone mass during growth and the mechanisms by which renal failure and steroid therapy interrupt these process. In addition, the limitations of DXA for detecting impaired bone mineralization in children with renal disease are reviewed and alternative approaches explored.  N. Ref:: 21

RESUMEN / SUMMARY:  - As steady improvement in short-term kidney graft survival and long-term outcomes prolongs the lives of transplant patients, responsibility for their care is shifting away from transplant specialists and into the hands of community nephrologists. Therefore, community nephrologists need to have a deeper understanding of immunosuppressive therapies than ever before. Pharmacologic immunosuppression has been continuously evolving over the past two decades. Azathioprine was introduced in the early 1960s. Introduction of cyclosporine (CsA) in 1983 revolutionized short-term outcomes after renal transplantation. The first monoclonal antibody immunosuppressant, OKT3, was introduced in 1986. The 1990s saw the introduction of a number of important new agents, including mycophenolate mofetil (MMF), tacrolimus, and a microemulsion CsA, as well as two new monoclonal antibodies. Combinations of these new agents, along with improving clinical care, have produced 1-year patient survival approaching 100% and graft survival exceeding 90%. The newest class of agents, the first of which is sirolimus, is called target of rapamycin (TOR) inhibitors and is used with CsA for maintenance therapy. Immunosuppressive drug therapy after kidney transplantation continues to evolve. There is a variety of pharmacologic combinations from which to choose, based on immunologic risk and side effect profiles. As new regimens are developed, ongoing communications between the transplant center and community nephrologists will be required to implement therapeutic changes and optimize patient care successfully.  N.

RESUMEN / SUMMARY:  - Cutaneous neoplasms are much more common in renal transplant recipients than in the general population, and are the most common malignancies in these patients. This is the case with basal cell carcinoma, and even more so with squamous cell carcinoma. Many risk factors for development of such malignancies are similar to those in the general population. However, in the transplant population, such cancers appear at an earlier age, behave more aggressively, and frequently appear at multiple sites. Therefore, diligence on the part of the patient and on the part of his or her health care providers is of utmost importance. Treatment options include reduction in immunosuppression, but preventive maintenance remains the primary focus of efforts to limit these malignancies.  N. Ref:: 37

RESUMEN / SUMMARY:  - Cyclosporin and tacrolimus have improved survival figures in organ transplantation. However, both drugs are potentially nephrotoxic. The immunosuppressive and nephrotoxic effects of both drugs appear to depend on the inhibition of calcineurin. Cyclosporin and tacrolimus cause acute (functional changes) and chronic nephrotoxicity (structural lesions in the kidney). These last important lesions include arteriolar hyalinosis, stripped interstitial fibrosis and tubular atrophy. It is possible that repeated episodes of renal ischaemia contribute to the development of chronic nephrotoxicity and then chronic allograft nephropathy. Cyclosporin and tacrolimus also induce arterial hypertension. Therefore, the beneficial effects of immunosuppression have been limited due to nephrotoxicity and arterial hypertension. Rapamycin, a novel immunosuppressive agent, that does not inhibit calcineurin, provides immunosuppression without nephrotoxicity. In fact, in the trials performed in Europe, sirolimus-treated immunosuppression patients exhibited a much better renal function than cyclosporin-treated patients. However, sirolimus can potentiate the nephrotoxic effect of cyclosporin. Therefore, when cyclosporin and sirolimus are used in combination, a reduction of the cyclosporin dose is desirable.  N.

RESUMEN / SUMMARY:  - Organ transplantation from cadaveric donors has a risk of cancer transmission. However, some reports indicate that kidneys bearing small carcinomas can be safely transplanted, as can other organs harvested from the same donor. We report herein the case of two allograft recipients (left kidney and heart with no evidence of tumor) who developed a renal carcinoma soon after transplantation. The initial tumor of the donor was a 17-mm tubulopapillary adenoma found on the right kidney, which was not transplanted. The left kidney recipient rejected all residual tumoral cells after graft removal and immunosuppression discontinuation. The heart recipient died 7 months after transplantation from metastasis of a renal carcinoma. This strongly suggests that circulating carcinoma cells were present at the time of organ retrieval and that they were not cleared by in situ perfusion. In contrast with the literature data, this report indicates that patients with small renal tubulopapillary tumors should not be considered for organ donation.  N. Ref:: 10

RESUMEN / SUMMARY:  - BACKGROUND: We describe a rare case of necrotizing fasciitis involving Candida albicans, an organism that has been reported to have a minimal potential for invasive soft tissue infection. In this case, immunosuppression, chronic renal failure, and a history of diabetes mellitus were predisposing factors. METHODS: The medical record and histopathologic material were examined. The clinical literature was reviewed for previous cases of C albicans necrotizing fasciitis. RESULTS: A review of the literature showed that in solid organ transplant recipients, localized fungal soft tissue infection is infrequent, with only 35 cases reported between 1974 and 1992. Necrotizing fasciitis caused by C albicans is extremely rare in the modern era of solid organ transplantation. CONCLUSIONS: The management of transplant patients at risk for invasive fungal infection warrants a high index of suspicion for fungal necrotizing fasciitis in the setting of wound infection and merits a thorough investigation for atypical pathogens.  N.

RESUMEN / SUMMARY:  - Over the past 3 decades, renal allograft survival has improved significantly as a result of the development of powerful immunosuppressive agents. Nevertheless, the overall half-life of renal allografts has increased marginally during that time period, owing to drug-related nephrotoxicity and chronic rejection. New immunosuppressive agents are being evaluated because of the need for a reduction in the dose of nephrotoxic calcineurin inhibitors and corticosteroids. Additional agents have demonstrated the ability to retard the onset of chronic rejection in preclinical transplant models. In concert with these efforts, approaches are in development to alleviate the ever increasing shortage of donor organs, including the as yet unrealized goals of successful and practical xenotransplantation and the bioartificial kidney. Further identification and development of novel agents that target the specific components of the allograft response will provide the key to the achievement of donor-specific tolerance, the “Holy Grail” of solid organ transplantation.  N.

TÍTULO / TITLE:  - Call for revolution: a new approach to describing allograft deterioration.

REVISTA / JOURNAL:  - Am J Transplant 2002 Mar;2(3):195-200.

AUTORES / AUTHORS:  - Halloran PF

RESUMEN / SUMMARY:  - I propose a set of definable entities in the renal transplant course, eliminating the need for the term ‘chronic rejection’. The status of a renal transplant can be defined by the presence and extent of rejection (T-cell-mediated or antibody-mediated); allograft nephropathy (parenchymal atrophy, fibrosis, and fibrous intimal thickening in arteries); transplant glomerulopathy; specific diseases; and factors which could accelerate progression. The level of function and the slope of the loss of function should be separately determined. This approach can be applied both in research and in clinical practice, and can be adapted to other organ transplants.  N. Ref:: 47

RESUMEN / SUMMARY:  - BACKGROUND: Acute graft rejection (AR) following renal transplantation results in reduced graft survival. However, there is uncertainty regarding the definition, aetiology and long-term graft and patient outcome of AR occurring late in the post-transplant period. AIM: To determine if rejection episodes can be classified by time from transplantation by their impact on graft survival into early acute rejection (EAR) and late acute rejection (LAR). MATERIALS AND METHODS: 687 consecutive adult renal transplant recipients who received their first cadaveric renal transplant at a single centre. All received cyclosporine (CyA)-based immunosuppression, from 1984 to 1996, with a median follow-up of 6.9 yr. Details were abstracted from clinical records, with emphasis on age, sex, co-morbid conditions, HLA matching, rejection episodes, patient and graft survival. ANALYSIS: Patients were classified by the presence and time to AR from the date of transplantation. Using those patients who had no AR (NAR) as a baseline, we determined the relative risk of graft failure by time to rejection. The characteristics of patients who had no rejection, EAR and LAR were compared. RESULTS: Compared with NAR, the risk of graft failure was higher for those patients who suffered a rejection episode. A much higher risk of graft failure was seen when the first rejection episode occurred after 90 d. Thus, a period of 90 d was taken to separate EAR and LAR (relative risk of 3.06 and 5.27 compared with NAR as baseline, p<0.001). Seventy-eight patients (11.4%) had LAR, 271 (39.4%) had EAR and 338 (49.2%) had NAR. The mean age for each of these groups differed (LAR 39.6 yr, EAR 40.8 yr compared with NAR 44 yr, p<0.003). The 5-yr graft survival for those who had LAR was 45% and 10-yr survival was 28%. HLA mismatches were more frequent in those with EAR vs. NAR (zero mismatches in HLA-A: 36 vs. 24%, HLA-B: 35 vs. 23% and HLA-DR: 63 vs. 41%, p<0.003). There was no difference in mismatching frequency between NAR and LAR. CONCLUSIONS: AR had a deleterious impact on graft survival, particularly if occurring after 90 d. AR episodes should therefore be divided into early and late phases. In view of the very poor graft survival associated with LAR, it is important to gain further insight into the main aetiological factors. Those such as suboptimal CyA blood levels and non-compliance with medication should be further investigated with the aim of developing more effective immunosuppressive regimens in order to reduce the incidence of LAR.  N.

RESUMEN / SUMMARY:  - PURPOSE OF REVIEW: Evidence from several transplant centers indicates that a substantial proportion of acute and chronic renal allograft rejection is caused by antibodies to donor antigens. Antibody-mediated injury arises despite potent anti-T cell pharmacological agents, and probably requires different therapy. RECENT FINDINGS: Acute humoral rejection occurs in 20-30% of acute rejection cases, has a poorer prognosis than cellular rejection, and is refractory to conventional immunosuppressive therapy. C4d deposition in peritubular capillaries of renal allografts has been demonstrated to be a sensitive and diagnostic in-situ marker of acute humoral rejection that correlates strongly with the presence of circulating donor-specific antibodies. Biopsies with chronic allograft arteriopathy or glomerulopathy also have a high frequency of C4d deposition and donor-specific antibodies. The vessels of other organs, notably the heart, can also be targets of humoral rejection. New polyclonal C4d antibodies work in paraffin sections. Pitfalls in C4d staining have been identified and must be considered in the valid interpretation of results. SUMMARY: As the histology is variable, the current diagnosis of humoral rejection in biopsies relies on the demonstration of C4d, a component of the classical complement pathway, in peritubular capillaries. The new classification of renal allograft rejection incorporates humoral and cellular mechanisms of injury, with the diagnostic criteria of each. This should prove useful in guiding clinical treatment, and stratifying drug trials, replacing obsolete terms such as ‘vascular rejection’. Specific therapeutic strategies for humoral rejection with controlled trials targeting the humoral limb of immunosuppression are needed.  N. Ref:: 47

RESUMEN / SUMMARY:  - Although the incidence of pneumonia after kidney transplantation is the lowest among all solid organ transplants, it is associated with high mortality rate (40-50%). We evaluated the efficacy of a protocol consisting of bronco-alveolar-lavage (BAL) for early microbiological diagnosis, reduction of the immunosuppressive therapy, and prompt administration of standardized antibiotic regimen in renal transplant recipients with severe pneumonia. Between 6/1989 and 5/1999, 40 kidney transplant recipients developed 46 episodes of severe pneumonia (hypoxia and/or infiltrate on the chest X-ray). According to protocol, in all these cases, a BAL was immediately performed and empirical antibiotic therapy was initiated with erythromycin and trimethoprim-sulfamethoxazole i.v. Furthermore, the immunosuppressive therapy was drastically reduced. Analyses of BAL fluid included cell differential count, cytopathologic examination and cultures for bacteria, fungi and viruses. Within 48 h, the therapy was switched to proper i.v. antibiotics, if necessary, according to the results of sensitivity testing of BAL specimens. The mortality rate was 12.5% (5 of 40). Mechanical ventilation was required in 20 cases (34.5%) and four of the patients that required intubation died. BAL alone established a diagnosis in 67.4% (31 of 46) of the patients. Bacteria were responsible for 61% of the episodes, with fungi responsible for 29% and viruses for 10%. Seven cases of Pneumocystis carinii pneumonia were treated with the prolongation of the initial therapy. We conclude that a combination of early detection of the responsible pathogen by BAL, aggressive reduction of the immunosuppressive therapy and the immediate empirical administration of erythromycin and trimethoprim-sulfamethoxazole is an effective strategy to treat pneumonia kidney transplantation (KTX) recipients.
