RESUMEN / SUMMARY:  - The incidence of cardiovascular disease (CVD) is very high in patients with chronic kidney (CKD) disease and in kidney transplant recipients. Indeed, available evidence for these patients suggests that the 10-year cumulative risk of coronary heart disease is at least 20%, or roughly equivalent to the risk seen in patients with previous CVD. Recently, the National Kidney Foundation’s Kidney Disease Outcomes Quality Initiative (K/DOQI) published guidelines for the diagnosis and treatment of dyslipidemias in patients with CKD, including transplant patients. It was the conclusion of this Work Group that the National Cholesterol Education Program Guidelines are generally applicable to patients with CKD, but that there are significant differences in the approach and treatment of dyslipidemias in patients with CKD compared with the general population. In the present document we present the guidelines generated by this workgroup as they apply to kidney transplant recipients. Evidence from the general population indicates that treatment of dyslipidemias reduces CVD, and evidence in kidney transplant patients suggests that judicious treatment can be safe and effective in improving dyslipidemias. Dyslipidemias are very common in CKD and in transplant patients. However, until recently there have been no adequately powered, randomized, controlled trials examining the effects of dyslipidemia treatment on CVD in patients with CKD. Since completion of the K/DOQI guidelines on dyslipidemia in CKD, the results of the Assessment of Lescol in Renal Transplantation (ALERT) Study have been presented and published. Based on information from randomized trials conducted in the general population and the single study conducted in kidney transplant patients, these guidelines, which are a modified version of the K/DOQI dyslipidemia guidelines, were developed to aid clinicians in the management of dyslipidemias in kidney transplant patients. These guidelines are divided into four sections. The first section (Introduction) provides the rationale for the guidelines, and describes the target population, scope, intended users, and methods. The second section presents guidelines on the assessment of dyslipidemias (guidelines 1-3), while the third section offers guidelines for the treatment of dyslipidemias (guidelines 4-5). The key guideline statements are supported mainly by data from studies in the general population, but there is an urgent need for additional studies in CKD and in transplant patients. Therefore, the last section outlines recommendations for research.

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:  - The prognostic utility of myocardial perfusion studies (MPS) such as thallium scintigraphy and dobutamine stress echocardiography (DSE) for stratifying cardiac risk among candidates for kidney or kidney-pancreas transplantation is uncertain. This study is a meta-analysis to determine the prognostic significance of MPS results on future myocardial infarction (MI) and cardiac death (CD) in patients with end-stage renal disease (ESRD) assessed for kidney or kidney-pancreas transplantation. MEDLINE was searched using combinations of MeSH headings and text words for transplantation, coronary artery disease, prognosis, end-stage renal disease, and noninvasive cardiac testing (nuclear scintigraphy and DSE) for primary studies. Studies were included if they reported MPS results and cardiac events in patients assessed for kidney or kidney-pancreas transplantation. Methodologic study quality and outcome data were independently abstracted in duplicate by two researchers. The relative risks (RR) of MI and CD were calculated using a random effects model. Twelve articles met all inclusion criteria; 12 studies reported CD, and 9 reported MI. In eight studies, thallium scintigraphy was used (four with pharmacologic stress, four with exercise stress), whereas four used DSE. When compared with negative tests, positive tests had a significantly increased RR of MI (2.73 [95% CI, 1.25 to 5.97]; P = 0.01) and CD (2.92 [95% CI, 1.66 to 5.12]; P < 0.001). Subgroup analyses of studies of diabetic patients indicated that positive tests were associated with a RR of CD 3.95 (95% CI, 1.48 to 10.5; P = 0.006) and a RR of MI 2.68 (95% CI, 0.95 to 7.57; P = 0.06) when compared with negative tests. In studies evaluating mixed populations of diabetic and nondiabetic patients, positive tests were associated with a RR of CD 2.52 (95% CI, 1.25 to 5.08; P = 0.01) and with a RR of MI 2.79 (95% CI, 0.85 to 9.21; P = 0.09) when compared with a negative test. The presence of reversible defects was associated with an increased risk of MI in diabetic patients and of CD in both subgroups; fixed defects were associated with an increased risk of CD but not MI. It is concluded that positive MPS are useful in identifying patients with significantly increased risk of future MI and CD in both diabetic and nondiabetic ESRD patients.

RESUMEN / SUMMARY:  - BACKGROUND: Interleukin 2 receptor antagonists (IL-2Ra) are increasingly used to treat renal transplant recipients. This study aims to systematically identify and summarize the effects of using IL-2Ra as induction immunosuppression, as an addition to standard therapy, or as an alternative to other antibody therapy. METHODS: Databases, reference lists, and abstracts of conference proceedings were searched extensively to identify relevant randomized controlled trials in all languages. Data were synthesized using the random effects model. Results are expressed as relative risk (RR), with 95% confidence intervals (CI). RESULTS: A total of 117 reports from 38 trials involving 4,893 participants were included. When IL-2Ra were compared with placebo (17 trials; 2,786 patients), graft loss was not significantly different at 1 year (14 trials: RR 0.84; CI 0.64-1.10) or 3 years (4 trials: RR 1.08; CI 0.71-1.64). Acute rejection was significantly reduced at 6 months (12 trials: RR 0.66; CI 0.59-0.74) and at 1 year (10 trials: RR 0.67; CI 0.60-0.75). At 1 year, cytomegalovirus infection (7 trials: RR 0.82; CI 0.65-1.03) and malignancy (9 trials: RR 0.67; CI 0.33-1.36) were not significantly different. When IL-2Ra were compared with other antibody therapy, no significant differences in treatment effects were demonstrated, but IL-2Ra had significantly fewer side effects. CONCLUSIONS: Given a 40% risk of rejection, seven patients would need treatment with IL-2Ra in addition to standard therapy, to prevent one patient from undergoing rejection, with no definite improvement in graft or patient survival. There is no apparent difference between basiliximab and daclizumab.

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

RESUMEN / SUMMARY:  - BACKGROUND: Numerous reports have appeared on lamivudine use for the treatment of hepatitis B virus (HBV) infection after renal transplantation (RT). However, the efficacy and safety of lamivudine after RT remain unclear. METHODS: The authors evaluated the efficacy and safety of initial lamivudine monotherapy in RT recipients with hepatitis B by performing a systematic review of the literature with a meta-analysis of clinical trials. The primary outcomes were hepatitis B (HB) e antigen (Ag) and HBV-DNA clearance (as measures of efficacy); the secondary outcomes were biochemical response (as measures of efficacy), dropout rate, and lamivudine resistance (as measures of tolerability). The authors used the random effects model of DerSimonian and Laird, and outcomes were analyzed on an intent-to-treat basis. RESULTS: The authors identified 14 clinical trials (184 patients); all of these were prospective cohort studies. The mean overall estimate for HBV-DNA and HBeAg clearance, alanine aminotransferase normalization, and lamivudine resistance was 91% (95% confidence interval [CI], 86%-96%), 27% (95% CI, 16%-39%), 81% (95% CI, 70%-92%), and 18% (95% CI, 10%-37%), respectively. HBeAg seroconversion rate was assessed in four (28%) trials and ranged between 0% and 46%. The P value was greater than 0.05 for our test of study homogeneity. There was no association between rate of patients who were male patients or had cirrhosis, race, age, lamivudine dose, and HBV-DNA or HBeAg clearance. Increased duration of lamivudine therapy was positively associated with frequency of HBeAg loss (r =0.51, P =0.039) and lamivudine resistance (r =0.620, P =0.019). Only 2 (14%) of 14 studies reported a dropout rate greater than 0%. CONCLUSIONS: Our meta-analysis showed that the majority of RT recipients with hepatitis B had high virologic and biochemical response with lamivudine. Tolerance to lamivudine was good. However, lamivudine resistance was frequent with prolonged therapy, potentially limiting its long-term efficacy after RT.

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

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

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

RESUMEN / SUMMARY:  - Patients with type 1 diabetes mellitus and end-stage renal disease may remain on dialysis or undergo cadaveric kidney transplantation, living kidney transplantation, sequential pancreas after living kidney transplantation, or simultaneous pancreas-kidney transplantation. It is unclear which of these options is most effective. The objective of this study was to determine the optimal treatment strategy for type 1 diabetic patients with renal failure using a decision analytic Markov model. Input data were obtained from the published medical literature, the United Network for Organ Sharing registry, and patient interviews. The outcome measures were life expectancy (in life-years [LY]) and quality-adjusted life expectancy (in quality-adjusted life-years [QALY]). Living kidney transplantation was associated with 18.30 LY and 10.29 QALY; pancreas after kidney transplantation, 17.21 LY and 10.00 QALY; simultaneous pancreas-kidney transplantation, 15.74 LY and 9.09 QALY; cadaveric kidney transplantation, 11.44 LY and 6.53 QALY; dialysis, 7.82 LY and 4.52 QALY. The results were sensitive to the value of several key variables. Simultaneous pancreas-kidney transplantation had the greatest life expectancy and quality-adjusted life expectancy when living kidney transplantation was excluded from the analysis. These data indicate that living kidney transplantation is associated with the greatest life expectancy and quality-adjusted life expectancy for type 1 diabetic patients with renal failure. Treatment strategies involving pancreas transplantation should be considered for patients with frequent metabolic complications of diabetes and for those patients who favor kidney-pancreas transplantation over kidney transplantation alone. For patients without a living donor, simultaneous pancreas-kidney transplantation is associated with the greatest life expectancy.

RESUMEN / SUMMARY:  - A full understanding of cellular dynamics is often difficult to obtain from time-lapse microscopy of single optical sections. New microscopes and image-processing software are now making it possible to rapidly record three-dimensional images over time. This four-dimensional imaging allows precise quantitative analysis and enhances visual exploration of data by allowing cellular structures to be interactively displayed from many angles. It has become a key tool for understanding the complex organization of biological processes in live specimens.  N. Ref:: 55

RESUMEN / SUMMARY:  - Pretransplant blood transfusions have been shown to improve organ allograft survival. However, the immunologic mechanism leading to this beneficial effect of blood transfusions is still unknown. The observation that transfusions sharing at least one HLA-DR antigen (human leukocyte antigen) with the recipient are more effective than HLA-mismatched transfusions has led to the hypothesis that CD(4+) regulatory T cells are induced that recognize allopeptides of the blood transfusion donor in the context of the self-HLA-DR molecule on the donor cells. In vitro studies showed that CD(4+) T cells recognizing an allopeptide in the context of self-HLA-DR are indeed able to decrease the alloimmune response of autologous T cells by affecting the activated T cells directly or indirectly by their modulatory effect on dendritic cells. The first studies in a patient with a well-functioning kidney graft after receiving an HLA-DR-matched pretransplant blood transfusion showed that the low organ donor-specific cytotoxic T-lymphocyte response after transplantation was indeed attributable to the activity of regulatory CD(4+) T cells.  N.

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:  - The 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor (statin)-mediated lowering of serum cholesterol has been associated with a significant reduction in cardiovascular morbidity and mortality. Recent studies suggest that additional non-lipid lowering effects (eg, endothelial stabilization, anti-inflammatory, antithrombogenic) may be important in modulating their effectiveness. Dyslipidemia is common in end-stage renal disease (ESRD), and hemodialysis patients have increased cardiovascular morbidity and mortality. Cerivastatin, a new statin with powerful low-density lipoprotein-cholesterol (LDL-C) lowering capabilities, possesses some unique non-LDL-C-mediated properties that may contribute to a reduction of coronary events in the patient with ESRD. The primary objective of this multicenter multinational study of 1,054 hemodialysis patients is to compare 2 years of treatment with cerivastatin (0.4 mg/d) versus placebo on the composite clinical event rate of myocardial infarction, sudden cardiac death, ischemic stroke, and the need for coronary arterial bypass graft (CABG) or percutaneous transluminal coronary angioplasty (PTCA) procedures in these patients. Changes in lipids, inflammatory proteins including heat stable C-reactive protein (hsCRP), interleukin-6 (IL-6), oncostatin-M, intracellular adhesion molecule-1 (ICAM-1) and monocyte-chemoattractant protein-1 (MCP-1), as well as markers of cardiac muscle pathology, such as troponin I and troponin T, will be assessed in a subset of patients. This study is the first of its kind to assess the effect of a statin on the reduction of cardiovascular morbidity and mortality in an incident hemodialysis population. It will determine whether treatment with cerivastatin can effectively reduce the significant cardiovascular morbidity and mortality.

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

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

TÍTULO / TITLE:  - End-stage renal disease in India and Pakistan: burden of disease and management issues.

RESUMEN / SUMMARY:  - In the absence of national registries, no reliable data are available on the incidence and prevalence of end-stage renal disease (ESRD) in India and Pakistan. The incidence of ESRD is likely to be higher than that reported from the developed world, with chronic glomerulonephritis being the most common cause, accounting for more than one third of patients, while diabetic nephropathy accounts for about one fourth of all patients in India. Patients are generally younger (mean age 42 years) at the time of detection of ESRD and two-thirds first see a nephrologist after they have reached end stage. Treatment of ESRD is a low priority for the cash-strapped public hospitals and in the absence of health insurance plans, less than 10% of all patients receive any kind of renal replacement therapy. The vast majority of patients starting hemodialysis die or stop treatment because of cost constraints within the first three months, and less than 2% patients are started on ambulatory peritoneal dialysis. Although renal transplantation is the cheapest option, only about 5% of all patients with ESRD end up having a transplant. Living related donor transplants constitute 30 to 40% of all transplants in India, but there is a conspicuous gender bias with female donors donating kidneys for their male relatives. Cadaveric transplantation has yet to pick up and accounts for less than 2% of all transplants. The enactment of legislation to regulate renal transplantation in India has not been able to prevent unrelated (paid) donor transplants, which constitute 60 to 70% of all renal transplants. Cyclosporine, azathioprine and prednisolone continue to be the backbone of post-transplant immunosuppression, with cyclosporine being stopped in a significant proportion at one year post-transplant to cut down costs. Increasing awareness of renal disease amongst the population and general practitioners could result in early diagnosis of chronic renal failure and give opportunity for preventive strategies to delay the onset of ESRD. Preemptive transplantation and use of generic cyclosporine can help bring down the costs of treatment. Innovative and affordable health insurance policies can also increase the number of patients who receive effective treatment for ESRD in these two countries.  N. Ref:: 10

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