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:  - Even though cardiovascular disease is the leading cause of death in patients with CRF and end-stage renal disease (ESRD), ill-conceived notions have led to therapeutic nihilism as the predominant strategy in the management of cardiovascular disease in these populations. The recent data clearly support the application of proven interventions in the general population, such as angiotensin-converting enzyme inhibitors and statins to patients with CRF and ESRD. The advances in coronary stents and intracoronary irradiation have decreased the restenosis rates in renal failure patients. Coronary artery bypass with internal mammary graft might be the procedure of choice for coronary revascularization in these patients. The role of screening for asymptomatic coronary disease is established as a pretransplant procedure, but it is unclear whether this will be applicable to all patients with ESRD. Future studies need to focus on unraveling the mechanisms by which uremia leads to increased cardiovascular events to design optimal therapies targeted toward these mechanisms and improve cardiovascular outcomes.  N.

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:  - 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:  - BACKGROUND: The incidence of delayed graft function in cadaveric grafts has increased over the last few years due in part to the large demand for cadaveric kidneys necessitating the use of kidneys from marginal donors. Calcium channel blockers have the potential to reduce the incidence of post-transplant acute tubular necrosis (ATN) if given in the peri-operative period. However, there is controversy surrounding their use in this situation with no consensus as to their efficacy. OBJECTIVES: To evaluate the benefits and harms of using calcium channel blockers in the peri-transplant period in patients at risk of ATN following cadaveric kidney transplantation. SEARCH STRATEGY: We searched the Cochrane Renal Group’s specialised register, the Cochrane Central Register of Controlled Trials (CENTRAL, in The Cochrane Library issue 2, 2003) MEDLINE (1966 to January 2003) and EMBASE (1980 - January 2003). The Trials Search Coordinator was contacted to develop the search strategy. SELECTION CRITERIA: Randomised controlled trials comparing calcium channel blockers given in the peri-transplant period with controls were included. Quasi-randomised trials were excluded. DATA COLLECTION AND ANALYSIS: Data was extracted and quality assessed independently by two reviewers, with differences resolved by discussion. Dichotomous outcomes are reported as relative risk (RR) and measurements on continuous scales are reported as weighted mean differences (WMD) with 95% confidence intervals (CI). MAIN RESULTS: Nine trials were suitable for inclusion. Treatment with calcium channel blockers in the peri-transplant period was associated with a significant decrease in the incidence of post transplant ATN (RR 0.57, 95%CI 0.40 to 0.82) and delayed graft function (RR 0.44, 95% CI 0.28 to 0.69). There was no difference between control and treatment groups in graft loss, mortality, requirement for haemodialysis. There was insufficent information to comment on adverse events. REVIEWER’S CONCLUSIONS: These results suggest that calcium channel blockers given in the peri-operative period may reduce the incidence of ATN post-transplantation. The result should be treated with caution due to the heterogeneity of the trials which made comparison of studies and pooling of data difficult.

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:  - BACKGROUND: To evaluate the association of long-term continuous mycophenolate mofetil (MMF) versus azathioprine (AZA) therapy and renal allograft function, as measured by the slope of reciprocal creatinine, we analyzed 49,666 primary renal allograft recipients reported to the United States Renal Data System between October 31, 1988 and June 30, 1998. METHODS: The primary study endpoint was defined as a greater than 20% decrease below a 6-month baseline of 1/serum creatinine (SCr) (slope of reciprocal creatinine) at or beyond 1 year after transplantation. A secondary endpoint was defined as reaching an SCr value greater than 1.6 mg/dL. Univariate Kaplan-Meier analysis and multivariate Cox proportional hazard models were used to investigate the risk of reaching the study endpoints. Multivariate analyses were corrected for potential confounding covariates. RESULTS: According to the Cox proportional hazard model, 12-month continued therapy of MMF versus AZA was associated with a protective effect against declining renal function, as measured by the slope of reciprocal creatinine (relative risk [RR]=0.84, confidence interval 0.78-0.91, P<0.001). For 24-month continued therapy of MMF versus AZA, MMF was associated with a further decreased risk for a decline in renal function (RR=0.66, confidence interval=0.57-0.77, P<0.001). Furthermore, MMF was associated with a protective effect against reaching the SCr threshold of 1.6 mg/dL (RR=0.80, P<0.001) beyond 12 months posttransplantation. CONCLUSIONS: Continuous use of MMF versus AZA was associated with a protective effect against declining renal function beyond 1 year after transplantation. Further study is needed to confirm that continued MMF therapy is protective against long-term deterioration in renal function.

INSTITUCIÓN / INSTITUTION:  - Data Analysis Center, Division of Transplantation, Department of Surgery, University of Calgary, Alberta, Canada.

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:  - BACKGROUND: Little information is available regarding the long-term incidence of end-stage renal disease (ESRD) and survival after the introduction of renal replacement therapy (RRT) in patients with type 1 diabetes. METHODS: We studied 1,075 patients with type 1 diabetes (onset age < 18 years) diagnosed between 1965 and 1979, who comprise the Allegheny County population-based registry. Onset of ESRD was defined as the introduction of RRT (dialysis or transplantation). RESULTS: Of 1,075 registrants, the living status of 975 patients (90.7%) and complication status of 798 patients (74.2%) were ascertained as of January 1, 1999. During the observation period, 104 patients (13.0%) developed ESRD, for an incidence rate of 521/100,000 person-years (95% confidence interval, 424 to 629). The cumulative incidence of ESRD was 11.3% at 25 years of diabetes. A significant decline was observed in 20-year cumulative incidence rates of ESRD for patients diagnosed between 1965 and 1969, 1970 and 1974, and 1975 and 1979 (9.1%, 4.7%, and 3.6%, respectively; P = 0.006). Of 104 patients with ESRD, 29 patients (28%) received dialysis alone, 44 patients (42%) received dialysis followed by kidney transplantation, 26 patients (25%) underwent successful transplantation alone, and 5 patients (5%) underwent a failed kidney transplantation followed by dialysis therapy. The cumulative survival rate 10 years after the introduction of RRT was 51.2%. The cumulative survival rate of dialysis therapy followed by kidney transplantation was significantly greater than that of dialysis therapy alone (P < 0.001). No difference was detected in survival between pancreas-kidney transplant recipients and kidney-alone transplant recipients (P = 0.7). CONCLUSION: The incidence of ESRD observed in this cohort has declined, probably reflecting the better glycemic and blood pressure control available since the early 1980s.  N. Ref:: 35

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:  - The Clinical Practice Guidelines Committee of the American Society of Transplantation developed a survey to review the policies of kidney transplant programs in the United States with respect to the management of the steadily expanding waiting list for cadaveric kidneys. The survey was sent to 287 centers, and 192 (67%) responded. The survey indicated that regular follow-up monitoring, most frequently on an annual basis, is required by the majority (71%) of programs. Patients considered to be at high risk and candidates for combined kidney-pancreas transplantation may be monitored more frequently. Annual screening for coronary artery disease is typically required for asymptomatic patients considered to be at high risk for covert disease. Noninvasive techniques are typically used, and a designated cardiologist is usually available to the transplant program. The dialysis nephrologist or the potential transplant recipient is expected to inform the transplant program of intercurrent events that may affect transplant candidacy. Standard health maintenance screening is required, together with the routine updating of serologic and other blood tests that may be relevant to the posttransplant course. Smaller transplant programs (<100 patients on the waiting list) are more likely to maintain closer contact with the wait-listed patients and to attempt to influence their treatment during dialysis and are less likely to cancel transplants because of unanticipated pretransplant medical problems. The work load necessitated by the follow-up monitoring of wait-listed patients was assessed and, in the absence of specific evidence-based information, a series of recommendations were developed to reflect current standards of practice and to suggest future research initiatives.

RESUMEN / SUMMARY:  - Nonmelanoma skin cancer (NMSC) is more frequent in immunocompromised patients, for example, patients with organ transplants. A number of studies have been published from different countries that present a similar picture of tumors in transplant patients. In addition, the behavior of these tumors is often more aggressive in this group of high-risk patients. The multitude of NMSC and precancerous lesions presents a clinical diagnostic and therapeutic challenge to the managing dermatologists. Technology is being developed to cope with the clinical diagnosis and medical adjunct treatment to broaden the therapeutic options. It is suggested that the optimal use of these new developments occurs if patients are seen in specialized clinics aimed at providing preventive measures, diagnosis, and treatment.  N. Ref:: 50

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:  - Definitive approaches to most infectious diseases following renal transplantation have not been established, leading to different approaches at different transplant centers. To study the extent of these differences, we conducted a survey of the practices surrounding specific infectious diseases at US renal transplant centers. A survey containing 103 questions covering viral, bacterial, mycobacterial and protozoal infections was developed. Surveys were sent to program directors at all U.S. renal transplant centers. Responses were received from 147 of 245 (60%) transplant centers and were proportionately represented all centers with respect to program size and geographical location. Pre-transplant donor and recipient screening for hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV) and cytomegalovirus (CMV) is uniform, but great discrepancy exists in the testing for other agents. HCV seropositive donors are used in 49% of centers. HIV seropositivity remains a contraindication to transplantation, although 13% of centers indicated they have experience with such patients. Post-transplant, there is wide variety in approach to CMV and Pneumocystis carinii (PCP) prophylaxis. Similarly divergent practices affect post-transplant vaccinations, with 54% of centers routinely vaccinating all patients according to customary guidelines in non-transplant populations. In contrast, 22% of centers indicated they do not recommend vaccination in any patients. We believe an appreciation of the differences in approaches to post-transplant infectious complications may encourage individual centers to analyse the results of their own practices. Such analysis may assist in the design of studies to answer widespread and important questions regarding the care of patients following renal transplantation.  N. Ref:: 38

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:  - 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:  - Cardiovascular disease (CVD) is the major cause of death among renal transplant recipients (RTRs), accounting for 17-50% of deaths. Both cardiomyopathy (congestive heart failure [CHF] and left ventricular hypertrophy [LVH]) and ischemic heart disease (IHD) are important complications of renal transplantation, although the morbid impact of cardiomyopathy has been overlooked until recently. Echocardiographic disorders and clinical CHF occur far more frequently in RTRs than in the general population, suggesting that renal transplantation may be a state of accelerated heart failure. In contrast, the incidence of IHD in RTRs is similar to that in the Framingham cohort. Age, diabetes, and gender remain important markers of risk for both disorders. Smoking, hyperlipidemia, and hypertension appear to be the major reversible risk factors for IHD, while anemia and hypertension are major reversible risk factors for cardiomyopathy. Definitive evidence on optimal intervention is lacking. Clinical trials are needed to define optimum targets for treatment of these risk factors, especially hypertension and anemia.  N. Ref:: 33

INSTITUCIÓN / INSTITUTION:  - Indian Health Service Kidney Disease Program, Albuquerque, New Mexico, USA. anarva@abq.ihs.gov

RESUMEN / SUMMARY:  - American Indians and Alaska Natives (AI/AN) experience high rates of chronic kidney disease. Several studies have demonstrated increased rates of early kidney disease among AI/AN, both in diabetics and non-diabetics. Among some tribes of the American Southwest, high rates of mesangiopathic glomerulonephritis have been documented. The epidemic of diabetes among AI/AN, which began in the middle of the 20th century, appears to be driving the increase in end-stage renal disease (ESRD). At the end of 1999, AI/AN had a national prevalence rate of treated ESRD that was 3.5 times greater than that of white Americans. There is significant regional variation as well as differences among the approximately 550 tribes that make up the American Indian community, with some tribes experiencing ESRD rates over twenty times the rate of whites. Although graft survival is excellent, AI/AN ESRD patients are less likely than whites to be placed on the transplant waiting list, and those listed wait longer for a transplant. Despite socioeconomic barriers and high rates of co-morbid illness, survival among AI/AN ESRD patients is better than among whites. The burden of kidney disease, particularly the multigenerational occurrence in some families, is perceived as a major threat to the well-being of native communities. There is a sense of urgency among tribal leaders to address this epidemic, and research that may decrease its burden is likely to be welcomed.  N. Ref:: 13

TÍTULO / TITLE:  - Basiliximab: a review of its use as induction therapy in renal transplantation.

AUTORES / AUTHORS:  - Chapman TM; Keating GM

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

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: 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:  - Histology compatible with minimal change glomerulonephritis and associated with nephrotic syndrome has been reported as an occasional curiosity post-renal transplantation. Focal segmental glomerulosclerosis (FSGS) has a recurrence rate of approximately 20%. Age <15 years, an aggressive clinical course of the original disease and diffuse mesangial proliferation on native biopsy, are considered predictive of relapse. At present there are no tests that can accurately predict the likelihood of recurrence. Data from paediatric patients whose primary disease was FSGS were, on average, 90% more likely to lose a graft from a live donor and 50% more likely to lose a graft from a cadaveric donor compared with recipients with structural disorders. Recurrence in a subsequent graft is expected if the first graft was affected, but not if the first graft did not demonstrate recurrence. The best-established and most effective treatment of recurrent disease requires both plasma exchange and cyclophosphamide. Familial focal and segmental glomerulosclerosis, although rare, is important to recognize, as it is a different syndrome to idiopathic FSGS of childhood and overall transplant survival is good. Adults with ‘secondary’ FSGS would not be expected to be at risk of recurrent disease in a renal transplant.  N. Ref:: 70

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:  - 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:  - 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:  - BACKGROUND: It remains unknown whether results of survival studies in anuric patients can be extrapolated to those who still have significant urine output. It is possible that after a prolonged period on dialysis, anuric patients are qualitatively different from patients with residual renal function. METHODS: We performed a retrospective review to study the cause of death of 296 peritoneal dialysis patients of our centre over a 7 year period, and compared the mortality and distribution of cause of death between patients with and without residual renal function. RESULTS: One hundred and forty-two cases (48.0%) died of vascular diseases, 82 cases (27.7%) died of infections and 72 cases (24.3%) died of other causes. Anuric patients had a higher overall mortality rate than non-anuric patients (14.9 vs 9.9%, P=0.0005), and the difference was almost completely attributed to the difference in mortality from vascular diseases (8.0 vs 4.1%, P<0.0001). Vascular disease was a more common cause of death in anuric patients than those with residual renal function (55.3 vs 40.8%, P=0.011). The difference was largely explained by the higher prevalence of sudden cardiac death in anuric patients (39 in 149 vs 19 in 147 cases). Patients without pre-existing cardiovascular disease more commonly died of vascular disease after they became anuric (47.4 vs 34.0%, P=0.017). The difference could not be explained by the longer duration of dialysis in anuric patients because there was no significant change in the distribution of cause of death with time on dialysis (chi-square test, P=0.341). CONCLUSIONS: Our observation suggests that peritoneal dialysis patients with and without residual renal function are qualitatively different. Studies on peritoneal dialysis adequacy and survival in anuric patients should only be extrapolated to the general dialysis population with caution.

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

RESUMEN / SUMMARY:  - This review describes advantages and limitations of registries that base their analyses on the census of all patients. Registries may utilize the random sample approach to enrich their data for more detailed and informative research. The Dialysis Outcomes and Practice Pattern Study (DOPPS) and its random sample approach is discussed here in detail, with examples on the value of this method. The DOPPS is currently being expanded to allow for even more valuable studies. This methodology can also be applied to large countries that do not have an existing registry, as it is an effective way of collecting detailed information at a relatively low cost that is representative of the country or population as a whole.  N.

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

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:  - 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:  - Cyclosporine A nephrotoxicity includes both functional toxicity and histological changes, whose seriousness is dependent upon the dose and the duration of the drug administration. Several vasoactive agents have been found to be implicated in cyclosporine induced nephrotoxicity, among which prostanoids and endothelins are the most important. In previous studies we were able to prevent the early stage (7 days) of cyclosporine (37.4 micromol [45 mg]/kg/day) induced nephrotoxicity in rats either by the administration, i) of OKY-046, a thromboxane A(2)synthase inhibitor, ii) of ketanserine, an antagonist of S(2)serotonergic, a(1)adrenergic, and H(1)histaminergic receptors and iii) of nifedipine, a calcium channel blocker, or by diet supplementation either with evening primrose oil or fish oil. All these protective agents elevated ratios of excreted renal prostanoid vasodilators (prostaglandins E(2), 6ketoF(1 alpha)) to vasoconstrictor (thromboxane B(2)), a ratio which was decreased by the administration of cyclosporine alone. Nifedipine averted the cyclosporine induced increase of urinary endothelin-1 release. All protections were associated with the reinstatement of glomerular filtration rate forwards normal levels whereas renal damage defence, consisting of a decrease of the cyclosporine induced vacuolizations, was variable. Ketanserine and evening primrose oil were the only agents which prevented the animal body weight loss. These data suggest that prostanoids and endothelin-1 may mediate functional toxicity while thromboxane A(2)is involved the morphological changes too, provoked in the early stage of cyclosporine treatment. However, other nephrotoxic factors and additional mechanisms could also be implicated in the cyclosporine induced nephrotoxicity.  N. Ref:: 91

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:  - 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.

RESUMEN / SUMMARY:  - BACKGROUND: Chronic allograft nephropathy (CAN) progresses rapidly during the first few months and slowly thereafter. Although the presence of CAN in protocol renal biopsies is a predictor of outcome, the reliability of this diagnosis according to Banff criteria has not been characterized. METHODS: Renal lesions were evaluated according to the Banff criteria in sequential protocol biopsies performed at 4 and 14 months in 310 biopsies obtained from 155 patients. RESULTS: CAN progressed from 40 to 53% (P=0.001) while serum creatinine remained stable (146 +/- 44 vs. 147 +/- 48 micromol/L, P=NS). Graft survival in patients with and without CAN in the first biopsy was 74 versus 91% (P < 0.05), and in the second biopsy 75 versus 94% (P < 0.05). In 54 patients (35%) no CAN was present in both biopsies, 39 (25%) showed progression to CAN, 19 (12%) showed regression of CAN, and 43 (28%) showed CAN in both biopsies. Graft survival was: 100%, 81.6%, 82.6% and 69.4%, respectively (P < 0.01). Assuming that CAN does not regress and sampling error is normally distributed, we estimated that 25% of biopsies cannot be properly classified. CONCLUSIONS: The increase in the incidence of CAN between the 4th and 14th month is lower than the proportion of misclassified biopsies. Thus, monitoring the progression of CAN by means of two sequential biopsies at 4 and 14 months is inaccurate. We suggest that progression of scarring be monitored by means of a donor and a protocol biopsy performed during the first year evaluated with a quantitative approach.

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:  - 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:  - 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:  - 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.

RESUMEN / SUMMARY:  - There has been a necessary change in attitude to transplantation; there is much less concern with short-term outcome and more concern with long-term kidney function, overall health and quality of life. Nephrotoxicity is an invariable consequence of long-term treatment with calcineurin antagonists and it is one of the most underestimated causes of late graft loss; it has been reported as a serious threat to both patient and graft survival following heart, liver and bone marrow transplantation. Sirolimus has been shown in many recent studies to be of great value in allowing patients to be weaned from cyclosporine with excellent patient and graft survival at 24 months a significant improvement in renal function with resolution of hirsutism and gum hyperplasia. Patients maintained on the combined regime of cyclosporine and sirolimus had significantly higher blood pressure, much more cyclosporine nephrotoxicity and hyperuricaemia at 12 months. The experimental studies have found cyclosporine and sirolimus potentiate with each other’s good and adverse effects. Cyclosporine therefore augments hyperlipidaemia caused by sirolimus, and sirolimus augments nephrotoxicity caused by cyclosporine. The results of these studies indicate that sirolimus is a suitable replacement for cyclosporine or tacrolimus for long-term maintenance therapy. By contrast the use of sirolimus in combination with cyclosporine results in potentiation of side effects. The principal disadvantages being increased cyclosporine associated nephrotoxicity and sirolimus associated hyperlipidaemia  N. Ref:: 32

RESUMEN / SUMMARY:  - Persisting polyomavirus replication is now widely recognized as a (re-)emerging cause of renal allograft dysfunction. Up to 5% of renal allograft recipients can be affected about 40weeks (range 6-150) post-transplantation. Progression to irreversible failure of the allograft has been observed in up to 45% of all cases. The BK virus strain is involved in the majority of the cases. Risk factors may include treatment of rejection episodes and increasing viral replication under potent immunosuppressive drugs such as tacrolimus, sirolimus or mycophenolate. The diagnosis requires the histological demonstration of nuclear polyomavirus inclusions in affected tubular epithelial cells. Interstitial inflammatory infiltrates and fibrosis become more prominent in the persisting disease and may be difficult to distinguish from (coexisting) rejection. Detection of polyomavirus-inclusion bearing cells (‘decoy cells’) in the urine and quantification of BK virus DNA in the plasma have been proposed as surrogate markers for polyomavirus replication and allograft disease, respectively. Antiviral treatment is not yet established; however, reports of treatment with cidofovir are encouraging. Current management aims at the judicious modification and/or reduction of immunosuppression which, in view of preceding or concurrent rejection, is not without risk.  N. Ref:: 51

RESUMEN / SUMMARY:  - Cyclosporine and tacrolimus reduce allograft rejection, improve allograft half-life and patient survival. Ironically, the nephrotoxicity of these agents may adversely affect allograft survival in renal transplant recipients or cause end-stage renal diseases in other solid organ and bone marrow transplant recipients. Acute dose-dependent and chronic non-dose-dependent nephrotoxicity has been reported in both transplant recipients and patients with autoimmune disorders. Preliminary evidence suggests that drug therapeutic monitoring has little value in the diagnosis or management of nephrotoxicity associated with calcineurin inhibitors. Although the exact mechanism of nephrotoxicity is not fully understood, several factors have been implicated in the pathogenesis of immunosuppressive-induced nephrotoxicity. Renal and systemic vasoconstriction, increased release of endothelin-1, decreased production of nitric acid and increased expression of TGF-beta are the major adverse pathophysiologic abnormalities of these agents. Reducing the dose of a calcineurin inhibitor, or using protocols without calcineurin inhibition may ultimately minimize the risk of drug toxicity and improve allograft and patient survival. New experiences with non-nephrotoxic agents and protocols including mycophenolate and sirolimus allow for early calcineurin inhibitor reduction or elimination without increasing the risk of allograft rejection.  N.

RESUMEN / SUMMARY:  - Renal transplantation is an accepted and successful treatment modality in elderly patients with end-stage renal disease. In comparison with maintenance dialysis, transplantation has been shown to confer a mortality benefit as well as improvements in quality of life in older individuals with end-stage renal disease. Despite this, overall outcomes of renal transplantation in elderly individuals have, in general, been less successful than those of younger renal transplant recipients. Largely, this has been due to the particular vulnerability of elderly patients to the immunosuppressive medications used in renal transplantation. This review article covers these issues in some detail and briefly discusses some of the pharmacokinetic, pharmacodynamic, physiological and immunological differences between younger and older transplant recipients. Elderly renal transplant recipients have both a higher rate of patient death and allograft loss censored for death. Upon multivariate analysis, age of the recipient is strongly associated with allograft loss independent of other known factors. Acute rejections are less frequent in older individuals; however the consequence of a rejection if it occurs is negative for long-term graft survival. On the other hand, death by infection is vastly increased in older versus younger renal transplant recipients. In general, the pharmacokinetics of the immunosuppressive agents are little affected by age, but the tolerance to these agents seems to decrease with increasing age. Elderly renal transplant recipients present a very difficult clinical challenge. As the elderly become an ever-increasing segment of the renal transplant population, new and innovative immunosuppressive strategies will have to be considered and applied.  N. Ref:: 75

RESUMEN / SUMMARY:  - An 18-yr-old man received a kidney graft from a 60-yr-old female cadaver donor on February 8, 1996. Postoperative course was uneventful and his serum creatinine level was stable at about 1.8 mg/dL. On April 30, 1999, he collided with a truck while riding a motor cycle. Macroscopic hematuria was observed and CT showed an extensive retroperitoneal hematoma. Because his anemia and hypotension were becoming worse after transfusion of 9 units of blood, he was operated on as an emergency case. A large rupture reaching the pelvis and calyces was observed in the upper pole of the grafted kidney. There were also numerous shallow lacerations, but the major arteries and veins were not injured. The rupture was closed by suturing the renal parenchyma with the peritoneum, and the other shallow lacerations were closed by suturing the renal capsule. The kidney could be salvaged without requiring hemodialysis. The serum creatinine was maintained at 2.1 mg/dL during follow-up. A review of the literature showed that 6 cases of traumatic renal graft rupture with salvage of the kidney have been reported. Our present case was the seventh, and was the most severe graft rupture reported so far.  N. Ref:: 7

RESUMEN / SUMMARY:  - Polyomavirus hominis 1, better known as BK virus (BKV), infects up to 90% of the general population. However, significant clinical manifestations are rare and limited to individuals with impaired immune functions. BKV has been associated with diverse entities such as haemorrhagic cystitis, ureteric stenosis, vasculopathy, pneumonitis, encephalitis, retinitis, and even multi-organ failure. In addition, BKV has been implicated in autoimmune disease and possibly cancer. Due to high prevalence and frequent reactivation, the role of BKV in some of these pathologies has been difficult to define. Development of BKV diseases is likely to require complementing determinants in the host, the target organ, and possibly the virus, that are subject to modulators such as immunosuppression. These complex aspects are highlighted in polyomavirus-associated nephropathy (PAN), an emerging disease in renal allograft recipients that may jeopardise the progress in renal transplantation accomplished in the past 10 years. Intervention is difficult due to the lack of specific antivirals and relies mostly on improving immune control. Diagnostic strategies using urine cytology and BKV load measurements in plasma have led to earlier diagnosis of PAN, which increased the success rate of intervention. Case series suggest that cidofovir might be effective, especially when combined with reduced immunosuppression.  N. Ref:: 156

RESUMEN / SUMMARY:  - BACKGROUND: Renal transplantation is the therapy of choice for patients with end-stage renal disease (ESRD). However, African Americans’ (AA) access to this modality is not commensurate with that of other races. This imbalance, coupled with AA disproportionately representing those with ESRD, has kept AA disadvantaged compared with other races, especially whites. METHODS: We reviewed published reports that examined the connection between race and the incidence of chronic renal failure, access to optimal therapy, and outcomes of renal transplantation. RESULTS: The incidence of ESRD in AA is 4 times greater than in whites, but AA remain less likely than whites to be referred for or undergo renal transplantation. Also, AA are at greater risk than whites to experience premature graft failure. CONCLUSIONS: ESRD management has improved dramatically with the advent of successful renal transplantation. However, AA remain significantly disadvantaged in both access and outcomes compared with whites. Further evaluation of underlying causes and development of specific remedies is warranted.  N.

RESUMEN / SUMMARY:  - BACKGROUND: Hepatitis C has been associated with an increased incidence of diabetes mellitus (DM) following renal transplantation (RT). METHODS: Patients who underwent RT between 1985 and 2001 were excluded if they showed DM prior to RT, graft survival of less than 90 days, and unknown anti-HCV status (n=15). Two groups (G1 and G2) were distinguished according to the immunosuppressive regimen: G1 (transplanted 1985-1996) received steroids, azathioprine, and cyclosporine (n=330), whereas G2 (1997-2000) received new drugs in several combinations (MMF in 87% and/or tacrolimus in 35% [n=240]). Patients with HCV antibodies pre- and/or post-RT were considered HCV-positive. Post-RT DM requiring prolonged treatment with oral antidiabetics or insulin (>1 month) was assessed using Kaplan-Meier curves and Cox analysis. RESULTS: G2 patients were significantly older, had a greater body mass index (BMI), and suffered significantly less from acute rejection episodes during the first year than G1 patients. Furthermore, fewer required maintenance steroids. HCV-positivity was more common in G1 than in G2 (n=96, 29.1% vs n=27, 11.3%). Six G2 patients were successfully treated with interferon pre-RT, achieving negative PCR-HCV status (maintained post-RT). DM incidence at 4 years was similar in G1 and G2 (8.8% and 8.2%). G1 HCV-positive patients showed a greater risk of developing DM than HCV-negative patients (28.0% vs 6.2% at 10 years; P=001). In G1, multivariate analysis showed that age, BMI, and HCV-positivity were significant risk factors predicting DM (relative risk, 5.7; 95% confidence interval 2.7-12). In G2 patients, HCV was not associated with an increased risk of DM; in the multivariate analysis only age appeared to be a risk factor. CONCLUSIONS: The reported relationship between hepatitis C and post-RT DM was not observed among patients receiving new immunosuppressive treatments. Confirmation of this finding requires extended follow up. The reduced use of steroids and effective pre-RT use of interferon may also be responsible for the benefit.

RESUMEN / SUMMARY:  - The anti-interleukin-2 receptor (anti-IL-2R) antibody therapy is an exciting approach to the prevention of acute rejection after renal allograft transplantation whereby immunosuppression is exerted by a selective and competitive inhibition of IL-2-induced T cell proliferation, a critical pathway of allorecognition. The anti-IL-2R antibodies specifically block the alpha-subunit of the IL-2R on activated T cells, and prevent T cell proliferation and activation of the effector arms of the immune system. The anti-IL-2R antibodies are used as induction therapy, immediately after renal transplantation, for prevention of acute cellular rejection in children and adults. During acute rejection, the IL-2Ralpha chain is no longer expressed on T cells; thus, the antibodies cannot be used to treat an existing acute rejection. Two anti-IL-2R monoclonal antibodies are currently in clinical use: daclizumab and basiliximab. In placebo-controlled phase III clinical trials in adults, daclizumab and basiliximab in combination with calcineurin inhibitor-based immunosuppression, significantly reduced the incidence of acute rejection and corticosteroid-resistant acute rejection without increasing the risk of infectious or malignant complications, and neither antibody was associated with the cytokine-release syndrome. Children who receive calcineurin inhibitors and corticosteroids for maintenance immunosuppression, as well as children who receive augmented immunosuppression to treat acute rejection, are at increased risk of growth impairment, hypertension, hyperlipidemia, lymphoproliferative disorders, diabetes mellitus, and cosmetic changes. In older children, the cosmetic adverse effects frequently reduce compliance with the treatment, and subsequently increase the risk of allograft loss. Being effective and well tolerated in children, the anti-IL-2R antibodies reduce the need for calcineurin inhibitors while maintaining the overall efficacy of the regimen; thus, the anti-IL-2R antibodies increase the safety margin (less toxicity, fewer adverse effects) of the baseline immunosuppression. Secondly, the anti-IL-2R antibodies decrease the need for corticosteroids and muromonab CD3 (OKT3) in children as a result of decreased incidence of acute rejection. The recommended pediatric dose of daclizumab is 1 mg/kg intravenously every 14 days for five doses, with the first dose administered within 24 hours pre-transplantation. This administration regimen maintains daclizumab levels necessary to completely saturate the IL-2Ralpha (5-10 microg/mL) in children for at least 12 weeks.The recommended pediatric dose of basiliximab for recipients <35 kg is 10 mg, and 20 mg for recipients > or =35 kg, intravenously on days 0 and 4 post-transplantation. This administration regimen maintains basiliximab levels necessary to completely saturate the IL-2Ralpha (>0.2 microg/mL) in children for at least 3 weeks.  N. Ref:: 88

RESUMEN / SUMMARY:  - BACKGROUND: Solid organ transplantation is becoming increasingly more common in the treatment of end-stage organ failure. Opportunistic fungal infections are a frequent life-threatening complication of transplantation. MATERIALS AND METHODS: In this article, a review of the infections in the different organ transplant recipients is presented. RESULTS: The incidence of fungal infections in organ transplant patients ranges from 2% to 50% depending on the type of organ transplanted, kidney recipients being the least frequent and liver recipients having the highest rate of infection. New antifungal medications and immunosuppressants have changed the spectrum of fungal treatment and prevention. CONCLUSION: Prompt recognition and treatment of infection is imperative for successful therapy. Further advancements in early detection and the development of less toxic medications will lead to refinements in the treatment of fungal infections.  N. Ref:: 66

RESUMEN / SUMMARY:  - Kidney transplantation represents a major medical victory in patients with whom dialysis and medical therapy have failed. To increase survival rates and optimize the use of limited organs, both patient care and immunosuppression therapy must be improved. Reduction in rejection episodes or severity of rejection may ultimately improve long-term allograft survival. Traditional engineered monoclonal antibodies have been associated with severe cytokine release reactions and an increased risk of opportunistic infections. Basiliximab and daclizumab are chimeric and humanized monoclonal antibodies which inhibit thymus-dependent lymphocyte proliferation. Interleukin-2 also affects the proliferation of natural killer cells, macrophages and monocytes, bursa-equivalent lymphocytes, epidermal dendritic cells, and lymphokine-activated killer cells. Interleukin-2 receptor antagonists have been shown to reduce the incidence of acute rejection without increasing the incidence of opportunistic infections or malignancy. Further studies are needed to evaluate the overall effect of these agents on long-term patient and allograft survival.  N. Ref:: 28

RESUMEN / SUMMARY:  - OBJECTIVE: To understand the current status of at-home self-care implemented by patients with renal transplantation of long-term survival, so as to provide the patients with adequate professional advice and follow-up care after discharge from hospital. METHOD: A survey was conducted in 248 patients who survived for over 3 years with functioning transplanted kidneys by utilizing a self-designed questionnaire. RESULTS: The at-home self-care was generally not well practiced by the patients with apparent lack of self-care awareness and abilities. Though the current status problematic, the survey showed that 96.32% of the patients wished to be informed about self-care knowledge and skills. CONCLUSION: The patients currently lack at-home self-care abilities and the medical staff should carefully design self-care plans tailored to the needs of individual patient to improve the survival of the patients and the transplanted kidneys as well.

RESUMEN / SUMMARY:  - Post-transplant diabetes mellitus (PTDM) is one of the feared complications of immunosuppressive therapy. Despite advances, including the introduction of the steroid-sparing calcineurin inhibitors, cyclosporine and tacrolimus, the incidence rate remains greater than 10% to 30%, especially in minority populations. PTDM increases the subsequent risk of both graft loss and patient death, and predisposes patients to all complications of diabetes, including retinopathy and neuropathy. Patients should be monitored closely, especially during the first 3 months post-transplant, and treated aggressively, should glucose intolerance be detected. Minimization of immunosuppression dose, diet, oral hypoglycemic agents, and insulin have all been used in the treatment of PTDM, however, the insulin-sensitizing agents have not been studied. It is hoped that newer immunosuppressive regimens and, ultimately, the ability to achieve tolerance will eventually solve the problem of PTDM.  N. Ref:: 53

RESUMEN / SUMMARY:  - Sirolimus (Rapamune), Wyeth-Ayerst, Madison, NJ) is a new, potent, immunosuppressant that is emerging as a foundation for long-term immunosuppressive therapy in renal transplantation. The drug acts during both co-stimulatory activation and cytokine-driven pathways via a unique mechanism: inhibition of a multifunctional serine-threonine kinase, mammalian target of rapamycin (mTOR). Although there is no a priori reason to assume it, sirolimus displays a synergistic interaction to enhance the efficacy of cyclosporin A (CsA). In trials wherein the concentrations of CsA and sirolimus were tightly controlled, rates of acute rejection episodes were < 10%, despite markedly reduced exposures to each agent. In pivotal multi-centre blinded dose-controlled trials, the rates of acute rejection episodes within 12 months following administration of 2 or 5 mg/day sirolimus in combination with CsA and steroids were reduced to 19 and 14%, respectively. Since the inhibitory effect of sirolimus disables virtually all responses to cytokine mediators due to the widespread involvement of mTOR in multiple signalling pathways, the agent is likely also to retard proliferation of endothelial and vascular smooth muscle cells, an important component of the immuno-obliterative processes associated with chronic rejection. The advantages of this unique therapeutic action combined with an intrinsic lack of nephrotoxicity are counterbalanced by myelosuppressive and hyperlipidaemic side effects. Ongoing studies are assessing whether the long-term benefits of sirolimus to permit reduction in exposure to or elimination of calcineurin inhibitors ameliorate the progression of chronic nephropathy, the condition that erodes long-term renal transplant survival.  N.

INSTITUCIÓN / INSTITUTION:  - Division of Nephrology and Immunology, University of Alberta, Edmonton, Canada. gsita@hotmail.com

RESUMEN / SUMMARY:  - The introduction of new immunosuppressive agents and protocols has improved outcomes for renal transplant recipients by decreasing the risk of rejection and by increasing the function and lifespan of the allograft. This article reviews the major changes in the combinations of therapies used: calcineurin inhibitors, target of rapamycin inhibitors, mycophenolate mofetil, non-depleting monoclonal versus depleting monoclonal and polyclonal antibodies for induction and increasing emphasis on protocols for reduction or avoidance of steroids and calcineurin inhibitors. The new agents with novel immunological targets such as anti-CD40 ligand, LEA29Y, FTY720, anti-CD20 (rituximab, Rituxan, Mabthera) and anti-CH52 (alemtuzumab, Campath), which are under development but have yet to survive the rigors of clinical trials are also discussed. In the presence of low early rejection rates, immunosuppressive therapy is setting new goals such as better graft function (glomerular filtration rates), reduction in adverse effects such as hypertension, hyperlipidaemia and drug toxicity and, above all, the prevention of late graft deterioration.  N.

INSTITUCIÓN / INSTITUTION:  - Division of Geographic Medicine and Infectious Diseases, New England Medical Center, Boston, Massachusetts 02111, USA. dsnydman@lifespan.org

RESUMEN / SUMMARY:  - A historical review of the development of cytomegalovirus hyperimmune globulin (CMV-IG, CytoGam) shows its increasing use in solid organ transplant (SOT) recipients, either alone or in combination with ganciclovir. A review of clinical trials of CytoGam in renal transplant recipients shows reductions in CMV-associated syndromes and fungal and parasitic superinfections, and increases in graft survival, while CytoGam prophylaxis trials in orthotopic liver transplant (OLT) recipients have produced reductions in severe CMV-associated disease and invasive fungal disease. A combination of CytoGam plus ganciclovir in OLT recipients has resulted in reductions in CMV hepatitis and infection, and CMV disease and viremia, plus a trend in improved 1- and 2-year survival rates.  N.

RESUMEN / SUMMARY:  - Sirolimus, which has a distinctive mechanism of action that inhibits cytokine-driven cell proliferation and maturation, provides an exciting addition to the immunosuppressive regimen for organ transplantation. A significant decrease in the number and severity of rejection episodes has been noted when sirolimus is used; it also offers the potential for patients to be withdrawn from steroids, making kidney transplantation an option for many more potential recipients. Toxic conditions such as hyperlipidemia, thrombocytopenia, and leukopenia become transient and manageable with reduction of the sirolimus dose and/or countermeasure therapy.  N. Ref:: 9

RESUMEN / SUMMARY:  - Existing studies support the use of varicella vaccine in a two-dose regimen in patients with renal disease prior to transplantation. Levels of anti-varicella zoster virus antibody should be monitored on a regular basis after immunization, and where a loss of a previously protective antibody titer occurs, a third booster dose should be considered pretransplant. Further data need to be collected regarding the use of the vaccine in seronegative patients who have already undergone transplantation.  N. Ref:: 22

RESUMEN / SUMMARY:  - While the number of cadaveric organ donors remains relatively stable, the number of patients awaiting transplantation continues to increase, creating a shortage of donor organs. To address this imbalance, there is interest in transplanting organs formerly considered marginal or undesirable. Thus, more organs are currently transplanted from living donors, older donors, hemodynamically unstable donors, non-heart-beating donors and donors with markers of prior hepatitis B virus (HBV) infection. A large number (up to 93.8%) of liver transplant seronegative recipients from anti-HBc antibody positive donors have acquired HBsAg after liver transplantation in the absence of immunoprophylaxis. Based on experience in liver transplantation programs, transmission of HBV from donors without HBsAg but with antibody to HBV core antigen (anti-HBc), although conventionally defined as evidence of resolved infection, can have adverse consequences on both graft and recipient. On the contrary, HBV appears to be in-frequently transmitted from HBsAg negative/anti-HBcAb positive kidney donors: the incidence of de novo HBsAg seropositivity after renal transplantation ranges between 0 and 5.2%. A significantly higher incidence of anti-HBc antibody seroconversion (without developing HBsAg) after renal transplantation with anti-HBc antibody positive donors was seen. However, anti-HBc antibody positive renal allografts should be considered, especially for recipients who have been successfully immunized with HBV vaccine. Prospective long-term studies are in progress to assess the risk of de novo HBV infection (HBsAg seroconversion) in renal transplant recipients who have not been successfully immunized with vaccine against HBV.  N.

RESUMEN / SUMMARY:  - Various opinions have been presented about the influence of age on the health-related quality of life (HRQOL) of patients on renal replacement therapy (RRT). Some authors sustain that age worsens HRQOL, while others show the opposite. It has been seen that a psychological adjustment occurs with aging, even when chronic illness is also present. In addition, elderly patients appear to adapt better to RRT than younger ones.  N. Ref:: 42

AUTORES / AUTHORS:  - Cecka JM

INSTITUCIÓN / INSTITUTION:  - UCLA Immunogenetics Center, Department of Pathology, UCLA School of Medicine, Los Angeles, California, USA.

RESUMEN / SUMMARY:  - The shortage of cadaver kidneys relative to increasing demand for transplantation has lead to a remarkable rise in transplantation from living donors. Based upon data reported to UNOS, the number of living donor kidneys transplanted in 2000 (5,106) nearly equaled the number of cadaver kidneys from preferred donors aged 6-50. HLA-mismatched siblings, offspring, spouses and other genetically unrelated donors accounted for nearly 80% of increased living donor transplantation during 1994-2000. Despite the increased use of poorly HLA-matched living donor kidneys, the actuarial 10-year graft survival rates for transplants between 1988-2000 were clustered between 53-57% for HLA-mismatched living donor grafts, except for offspring-to-parent transplants (49%) when the recipients were generally older. The 10-year survival rate for 96,053 cadaver grafts was 38% during the same period. The 5-year graft survival rates for more recent (1996-2000) cadaver donor transplants were 66%, 62% and 56% for recipients of first, second and multiple grafts, respectively (p < 0.001). The comparable results among recipients of living donor kidneys were 67%, 66% and 59% (p = ns). The 5-year graft survival rates for HLA-matched first grafts were 7% higher than those for HLA-mismatched transplants when the kidney was from a living or cadaver donor. HLA-identical sibling transplants provided the best long-term graft survival (85% at 5 years and a 32 year half-life). Even with improved crossmatch tests and stronger immunosuppression, sensitization was associated with 8% lower graft survival at 5 years and with a higher rate of late graft loss among first cadaver kidney recipients. Sensitization also was associated with an increase in delayed graft function from 22% of unsensitized first transplant recipients to as much as 36% among multiply retransplanted patients. Recipient race was a key factor in long-term graft survival of both living and cadaver donor kidneys. The rate of late graft loss was double among blacks compared with recipients with other racial origins whether the kidney was from a living or cadaver donor. Black recipients accounted for 29% of first cadaver transplants during 1996-2000, but only 14% of living donor grafts. Thus an important component of long-term differences in graft survival comparing living and cadaver donor transplants is the disparate racial demographics. Both the recipient and donor populations are aging. The proportion of cadaver kidney recipients over age 50 increased from 26% to 45% and the proportion of living donor kidney recipients over age 50 rose from 10% to 35% between 1988 and 2000. The aging population affects the transplant outcome as 65% of graft losses among young recipients (ages 10-15) were attributed to acute or chronic rejection compared with only 25% of grafts lost among patients over age 60. More than half of graft losses among older recipients were due to death with a functioning graft. Kidneys from donors over age 60 comprised 9% of first cadaver transplants and yielded a 50% 5-year graft survival rate compared with 70% when the donor was aged 19-45. Kidneys from donors over age 60 accounted for only 3% of first living donor transplants and their 84% 5-year graft survival rate was comparable to that for younger donor kidneys. Despite declining immunological graft losses with advancing recipient age, the effect of HLA matching was similar among recipients of first cadaver transplants aged 50 or under and those over age 50. Completely HLA-mismatched grafts had a 10% lower 5-year graft survival rate than HLA-matched grafts when the recipient was over 50 compared with a 14% lower survival rate in younger recipients. The graft half-lives were shorter by 5-7 years for HLA-mismatched kidneys transplanted to older or younger recipients, respectively.

RESUMEN / SUMMARY:  - Renal replacement therapy (RRT)--encompassing hemodialysis, peritoneal dialysis, and kidney transplantation—provides life-sustaining treatment for the expanding end-stage renal disease (ESRD) population. There is an excess burden of ESRD in African-American, Hispanic, Native Americans, and Asian/Pacific Islanders. Moreover, there is mounting evidence to suggest that significant racial and ethnic disparities exist in RRT—including referral and initiation of dialysis, adequacy of dialysis, and anemia management—with non-white patients usually at a disadvantage. In addition, there are cultural and sociodemographic differences that lead to racial variation in the choice of ESRD modality. Lastly, in certain ethnic ESRD populations, there are a series of complex issues, from biologic to socioeconomic, which limit kidney transplantation—the treatment of choice. Despite these inequalities, which are often associated with negative outcomes, these non-white groups have better hemodialysis survival rates than white patients. It is essential to develop strategies to address the disparities in ESRD treatment among minority groups in order to minimize the differences in RRT provision and identify the factors that confer improved dialysis survival-thus improving care for all Americans with kidney disease.  N.

REVISTA / JOURNAL:  - Clin Transpl 2001;:237-46.

AUTORES / AUTHORS:  - Cho YW; Cecka JM

RESUMEN / SUMMARY:  - Based on more than 20,000 cadaver donor transplants reported to UNOS between 1991-2000 with crossmatch results, the following observations were made: 1. One-hundred sixty-nine transplants performed despite a positive T-cell NIH crossmatch (usually with an historical serum sample) were reported to UNOS and had 5%, 6%, 7%, and 11% lower graft survival at one, 6, 12, and 24 months after transplantation compared with negative crossmatch transplants, respectively. 2. Transplants with a positive T-cell FCXM (n = 714) yielded 4%, 7%, and 9% lower graft survival at one, 6, and 12 months after transplantation compared with negative crossmatch transplants, respectively. 3. Transplants with a positive B-cell crossmatch using NIH, Wash, AHG or flow cytometry XM yielded statistically significantly lower (4-6%) graft survival rates compared with B-cell negative crossmatch transplants. 4. The differences in graft survival rates comparing recipients with a positive versus a negative T-cell crossmatch test (NIH, AHG, and FCXM) were significant in univariate analyses; however, only the NIH and FCXM showed a significant effect on graft survival after adjustment of other factors in a multivariate analysis. 5. Regrafted patients with a positive T- and B-cell FCXM experienced a higher incidence of primary nonfunction (12%) compared with those who had a negative T- and B-cell FCXM (1%; P < 0.001). Flow cytometric or ELISA screening of patient sera in addition to conventional cytotoxic crossmatch tests can provide additional information to aid in the final decision of renal transplantation.

RESUMEN / SUMMARY:  - 1. The rate of transfusion decreased from 64% in 1992 to 36% in 2000. This need for transfusions continued despite the introduction of erythropoetin. Females were transfused more frequently than males. SLE patients were transfused more often than those with other diseases. 2. Transfusions no longer had a beneficial effect on the outcome of transplantation, but rather with more transfusions, the graft outcome became lower, as might be expected. 3. Rejection of a kidney transplant had the strongest effect on sensitization, followed by transfusion and then pregnancies. Females were more susceptible to sensitization than males. Although non-transfused males should not have been sensitized, as many as 13% were reported to have antibodies. As many as 20% of nulliparous females without transfusions also were reported to have antibodies. 4. SLE patients were most often sensitized among patients with various diseases. Females of all diseases were more sensitized than males. 5. Unsensitized regraft patients had a 3% lower 3-year graft survival than unsensitized first graft patients. Among sensitized patients, regraft patients had a 4% lower graft survival than sensitized first graft patients. 6. Patients with polycystic kidney disease had the highest 3-year graft survival in both the sensitized and non-sensitized patients. Sensitization to a PRA level of less than 50% was not detrimental to patients with all the various diseases. 7. For cadaver donor regraft patients, HLA-DR mismatch had a greater effect than AB mismatch. There was a 10 percentage point lower 3-year graft survival in cadaver donor regraft patients mismatched for 2 DR antigens than mismatched for 0 DR antigens. 8. For living donor transplants, regrafts from 0 AB or 0 DR mismatched transplants had the same graft survival as first transplants.

RESUMEN / SUMMARY:  - Living organ donation has developed into an important therapeutic option in transplantation medicine. However, there are some medico-ethical problems that come along with the increasing reliance on this organ source. One of these concerns is based on the observation that many more women than men function as living organ donors. Whereas discrimination and differential access have been extensively discussed in the context of cadaveric transplantation and other areas of health care, the issue of gender imbalance in living organ donation has received less attention. This paper presents relevant data from the Eurotransplant and UNOS transplantation systems (1) and discusses possible explanations for the documented gender discrepancies. The conclusion calls for a review of existing practice guidelines in order to secure effective protection of particularly vulnerable potential donors and an equitable donor-recipient-ratio in living organ donation.  N.

RESUMEN / SUMMARY:  - One of the aims of transplantation is to restore the potential for a full life to individuals with ESRD. To obtain this strategies that allow better and longer allograft function and a reduction in adverse events that lead to premature death are required. To this end, the recommendations below showed reduce cardiovascular disease and help present and future transplant recipients live a full life. Focusing on traditional risk factors (hypertension, hyperlipidemia, discontinuation of smoking, and prevention and treatment of diabetes mellitus) in patients at risk and striving for the recommended targets will have the greatest clinical benefit. These strategies should begin in the pre-dialysis and dialysis phases in order to reduce the cumulative burden of disease. Failing this, early and hopefully pre-emptive transplantation should be the goal.  N. Ref:: 112

RESUMEN / SUMMARY:  - Transplant pharmacotherapy evolves as new agents are investigated and approved for use. Clinical immunosuppression has been plagued with maintaining a balance between rejection of the transplanted organ and complications of over-immunosuppression, including infection and malignancy. Clinicians must understand current immunosuppressive regimens and their associated effects when caring for transplant patients. While all transplant patients receive some form of immunosuppressive therapy, the combinations and choices increase as new drugs are developed. In the critical and acute care settings, newly transplanted patients will likely receive induction therapy. The goal of induction therapy is to increase long-term patient and allograft survival while preventing or reducing rejection episodes. Several agents are available for induction therapy, and each transplant center designs its own protocol. The foundation for maintenance therapy rests on the combining immunosuppressives to prevent rejection through a variety of pathways. An understanding of the mechanism of action and additive effects of a drug allows practitioners to optimize therapy while decreasing adverse effects. Immunosuppressive therapy offers potential for reducing detrimental patient outcomes and improving allograft survival. It is well established that repeated rejection episodes correlate with poor long-term graft survival. Challenges facing researchers and clinicians focus on improved patient outcomes and options to address financial constraints of transplantation.  N. Ref:: 33

RESUMEN / SUMMARY:  - Kidney transplant has become a viable option for patients with end-stage renal disease (ESRD). The number of kidney transplants has steadily increased during the past 50 years. Advances in surgical technique and immunosuppressive drugs have led to significant improvements in survival rates. Many chronic diseases that lead to ESRD negatively affect nutritional status. To minimize nutritional depletion and optimize nutritional status, a complete and thorough evaluation by a registered dietitian should be performed. The posttransplant nutritional goal is to provide adequate nutrition to promote wound healing and anabolism, to prevent infection, and to minimize side effects of medications. Providing adequate nutrition and reducing the long-term side effects are essential for graft survival in kidney transplant recipients  N. Ref:: 30
