The Fixed Dose Combination of Sofosbuvir and Velpatasvir is Safe and Effective in Patients of Chronic Hepatitis C With End-stage Renal Disease. J Clin Exp Hepatol 2024; 14:101367. [PMID: 38558861 PMCID: PMC10981127 DOI: 10.1016/j.jceh.2024.101367] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 02/14/2024] [Indexed: 04/04/2024] Open
Abstract
Background The burden of hepatitis C virus (HCV) in India is alarming, with a major share of this virus being witnessed in patients with end-stage renal disease (ESRD). A pan-genotypic combination of sofosbuvir and velpatasvir is found to be safe, effective, and economical in resource-constraint countries such as ours. However, there are scanty data on the efficacy and safety of sofosbuvir and velpatasvir combination in patients with ESRD. Hence, we performed this study to evaluate the safety and efficacy of the combination of sofosbuvir and velpatasvir in patients of chronic hepatitis C (CHC) with ESRD. Methods This is an observational study comprising of 40 CHC patients with ESRD on maintenance hemodialysis. All patients were treated with a fixed-dose combination of sofosbuvir and velpatasvir for 12 weeks in case of non-cirrhotic or compensated cirrhosis and 24 weeks in case of decompensated cirrhosis. The efficacy was assessed by sustained virological response defined by negative HCV RNA at 12 weeks (sustained virological response [SVR] 12) post treatment, and safety was assessed by recording any side-effects of all patients. Results Out of the 40 patients enrolled in our study, majority were non-cirrhotic (77%), and all were treatment-naive. The mean age was 49.87 ± 12.13 years, and 80% patients were male. The mean baseline HCV RNA was 2.61 ± 7.83 × 106 IU/ml. All the 40 patients (100%) achieved undetectable HCV RNA at the end of treatment; however, 39 patients (97.5%) achieved SVR 12. There was no significant deterioration of estimated glomerular filtration rate (eGFR) after completion of antiviral therapy as compared to the baseline eGFR (13.27 ± 10.32 vs13.54 ± 11.38, P = 0.54). None of the patients reported any serious adverse effects during treatment. Conclusion The fixed-dose combination of sofosbuvir and velpatasvir is effective and has showed excellent safety profile in patients of CHC with ESRD.

Abstract
More options regarding the choice of direct-acting antivirals (DAAs) are helpful for avoiding individual limitations in treating hepatitis C virus (HCV) infection. We aimed to assess the efficacy and tolerability of grazoprevir (GZR)/elbasvir (EBR) treatment in genotype-1b (GT-1b) HCV-infected liver or kidney transplant recipients. In this phase 4, single-arm, open-label, multicenter trial, patients received GZR 100mg/EBR 50mg daily for 12 weeks. Patients with any HCV infection other than genotype-1b (GT-1b), liver decompensation, human immunodeficiency virus or hepatitis B virus co-infection, a history of NS5A inhibitor exposure, or any severe drug-drug interactions (DDIs) were excluded. The primary endpoint was sustained virologic response at 12 weeks posttreatment (SVR12). Of the 14 patients (10 kidney and 4 liver transplant subjects) enrolled in this study, 9 (64%) were females; the median age was 64.0 (range: 43-73) years. The regularly used immunosuppressants were tacrolimus (93%), everolimus (29%), and sirolimus (7%), with patient blood levels easily managed and generally stable (all p> 0.05 in quantile regression analysis). The rate of SVR12 was 100% in intent-to-treat analysis. Only one patient discontinued GZR/EBR therapy at 6 weeks posttreatment due to a treatment-unrelated adverse event (AE); however, this patient remained achieving SVR12. Most AEs were mild in severity and deemed to be not treatment-related. No organ rejection episodes or deaths occurred during the study period. The single-tablet regimen of GZR/EBR for 12 weeks is highly effective and well tolerated in GT-1b HCV-infected liver or kidney transplant recipients, and its DDIs are generally easy to manage.

Abstract
INTRODUCTION India is witnessing high hepatitis C virus (HCV) infection burden in patients of chronic kidney disease. Due to unavailability of costly Kidney Disease Improving Global Outcomes-recommended directly acting antiviral drugs, a widely available pan-genotypic combination of Sofosbuvir and Velpatasvir can become an economical option. Data regarding treatment experience of sofosbuvir-velpatasvir combination in chronic kidney disease is scarce. No data from India have been published in patients on renal replacement therapies till now. METHODS This retrospective analysis included all patients of end-stage renal disease on maintenance hemodialysis with treatment-naïve chronic HCV infection treated with sofosbuvir (400 mg) and velpatasvir (100 mg) fixed-dose combination. Pretreatment routine investigations were performed, which included HCV viral load, genotype, fibro scan, endoscopy for esophageal varices, and portal vein Doppler. The patients were followed up with HCV viral load to declare sustained virologic response. RESULT patients were included with a mean age of 39.8 ± 10.8 years, and 77.4% were male. Genotype 1 was found to be most prevalent (67.7%), with a median viral load of 106copies/ml. Six (19.3%) patients had hepatitis B virus co-infection. Three (9.7%) patients had cirrhosis. Sustained virologic response (SVR12) was achieved in 30 (96.8%) patients, and one (3.2%) patient had relapse. Furthermore, 14 (45.2%) patients underwent renal transplantation, and none of them had relapsed. Dyspepsia (9.7%) was the most common side effect observed with no major adverse effect. CONCLUSION Our study showed excellent efficacy with the safety profile of this drug combination in end-stage renal disease patients. However, larger prospective studies and multicenter randomized controlled trials are needed for further confirmation.

Abstract
OBJECTIVES The preferred modality for renal replacement therapy is renal transplantation. Marked improvements in early graft survival and long-term graft function have made renal transplantation a more cost-effective alternative to dialysis. The presence of liver disease in the posttransplant period adversely affects graft function and survival. Determining the cause of deranged liver function tests can be helpful in treating the underlying cause, leading to improved graft survival and overall quality of life in patients after renal transplant. Here, we determined the frequency of hepatotropic viral infections leading to deranged liver function tests in renal transplant recipients. MATERIALS AND METHODS Our study included 132 patients with deranged liver function tests who had undergone renal transplant within the past 6 months. Reactivity and nonreactivity of hepatotropic viruses leading to deranged liver function tests were recorded. RESULTS Average age of patients was 37.17 ± 8.75 years. There were 84 male (63.64%) and 48 female (36.36%) patients. Rates of hepatitis C virus antibodies and hepatitis B surface antigen were 62.88% (83/132) and 37.12% (49/132), respectively, whereas no patients had hepatitis E virus immunoglobulin M antibodies or hepatitis A virus immunoglobulin M antibodies. CONCLUSIONS Among the hepatotropic viral infections leading to deranged liver function tests in renal transplant recipients, hepatitis B virus accounted for a small fraction. In contrast, hepatitis C virus was highly prevalent in transplant recipients who developed deranged liver function tests. Renal transplant recipients with hepatic viral infections have worse patient and allograft survival after transplant compared with noninfected renal transplant recipients. We recommend that transplant candidates be screened for hepatitis B and C virus infection, thus allowing increased graft survival and improved quality of life in renal transplant recipients.

Abstract
Hepatitis C virus (HCV) is a common cause of increased morbidity and mortality in kidney transplant patients. It is associated with posttransplant glomerulonephritis, chronic allograft nephropathy, and New Onset Diabetes after Transplant (NODAT). In the past, HCV was difficult to treat due to the presence of interferon alpha-based therapies that were difficult to tolerate and were associated with adverse side-effects, such as the risk of rejection. With the advent of oral directly acting antiviral therapies, the landscape for HCV and transplantation has changed. These agents are highly effective and well tolerated with minimal side-effects. Sustained viral response rates in excess of 90% are achieved with most current treatment regimens active against all HCV genotypes. These new agents may show an improvement in graft and patient survival while essentially eliminating the risk of acute rejection from the use of prior interferon-based HCV therapies. These agents may also result in an improvement in organ allocation for HCV donor/HCV recipient transplantation. This review is meant to discuss the epidemiology of HCV, the new oral direct-acting antiviral agents (DAAs) and future opportunities for research in the field of HCV related transplantation.

Abstract
Well-tolerated, ribavirin-free, pangenotypic hepatitis C virus (HCV) treatments for transplant recipients remain a high priority. Once-daily glecaprevir/pibrentasvir demonstrates high rates of sustained virologic response at 12 weeks posttreatment (SVR12) across all major HCV genotypes (GTs). This trial evaluated the safety and efficacy of glecaprevir/pibrentasvir for patients with chronic HCV GT1-6 infection who had received a liver or kidney transplant. MAGELLAN-2 was a phase 3, open-label trial conducted in patients who were ≥3 months posttransplant. Patients without cirrhosis who were HCV treatment-naive (GT1-6) or treatment-experienced (GT1, 2, 4-6; with interferon-based therapy with or without sofosbuvir, or sofosbuvir plus ribavirin) received glecaprevir/pibrentasvir (300/120 mg) once daily for 12 weeks. The primary endpoint compared the percentage of patients receiving glecaprevir/pibrentasvir with SVR12 to a historic SVR12 rate based on the standard of care. Safety of glecaprevir/pibrentasvir was assessed. In total, 80 liver transplant and 20 kidney transplant patients participated in the trial. Most patients had no or minimal fibrosis (80% had fibrosis scores F0-F1) and were infected with HCV GT1 (57%) or GT3 (24%). The overall SVR12 was 98% (n/N = 98/100; 95% confidence interval, 95.3%-100%), which exceeded the prespecified historic standard-of-care SVR12 threshold of 94%. One patient experienced virologic failure. One patient discontinued because of an adverse event considered to be unrelated to treatment; this patient achieved SVR12. Adverse events were mostly mild in severity, and laboratory abnormalities were infrequent. CONCLUSION Once-daily glecaprevir/pibrentasvir for 12 weeks is a well-tolerated and efficacious, ribavirin-free treatment for patients with chronic HCV GT1-6 infection who have received a liver or kidney transplant.

Abstract
BACKGROUND The objectives of this pilot study were to assess the efficacy and safety of an interferon-free sofosbuvir and ribavirin combination regimen to treat chronic hepatitis C virus (HCV) infection in kidney transplant recipients and to study the impact of sofosbuvir on calcineurin inhibitor (CNI) drug levels. METHODS A total of 10 kidney transplant recipients with chronic HCV infection were included in the study. All received sofosbuvir and ribavirin combination therapy. The virological response to therapy and the adverse effects of the drugs were studied. The area under the curve (AUC) and pharmacokinetic data of levels of CNI were compared while the patients were receiving sofosbuvir and ribavirin drugs and when they were no longer on these drugs. RESULTS In all, 9 of 10 patients (90%) achieved rapid virological response (RVR) with undetectable HCV RNA at 4 weeks and the remaining patient achieved undetectable HCV RNA at 8 weeks. A sustained virological response was seen at 3, 6 and 12 months and was maintained in all 10 patients (100%). The important aspect of the study is the effect of treatment with the sofosbuvir-ribavirin combination regimen on the CNI AUC levels, which resulted in a reduction in the CNI AUC. While used as part of triple-drug immunosuppression, no change in the dose of CNI (tacrolimus and cyclosporine) was required based on measurement of C0 levels. CONCLUSIONS The sofosbuvir and ribavirin combination therapy is effective and safe to treat HCV infection in the post-renal transplant setting. There is a need for close CNI level monitoring while these patients are on sofosbuvir therapy. With therapy and viral clearance, there could be reduction in CNI levels due to increased clearance of CNI drugs, which is shown by the AUC measurements. This could be important for patients at high risk for rejection.

Abstract
OBJECTIVE Much of the related researches have reported the correlation between renal transplantation and different tumors in the post transplant recipients. However, there are not exact essays revealed that renal transplantation is definite causation for liver carcinoma, thus we systematically evaluated the association between renal transplantation and the risk of liver carcinoma in this meta-analysis from all available researches. METHODS All useful data were collected through searching of PubMed and Web of Science until the date of 31 September 2015. Random-effects model were adopted to calculate the standardized incidence ratio and 95% confidence interval (CIs) of the risk of liver carcinoma among renal transplant recipients. Other statistical analyses like heterogeneity tests, sensitivity analysis and publication bias were also performed in this meta-analysis. RESULTS Among 17,4256 kidney transplant cases and 25,6736 patients-years observation, 9136 post-transplant cancers were diagnosed. We identified a 2.08-fold higher standardized incidence rate (SIR) (95% confidence interval (CI): 1.24-3.47, P=0.005) of liver carcinoma following renal transplantation compared with the general population. Observation and publication bias were not observed in this study. CONCLUSION This study suggested that the risk of liver carcinoma among renal transplant recipients with chronic hepatic disease is higher than general population. Such results alert clinical doctors the importance of anti-virus therapy with chronic virus hepatitis and enough attention of periodic liver screening with chronic liver diseases in renal transplant recipients.

Abstract
BACKGROUND The impact of hepatitis C virus (HCV) infections on patient long-term survival after renal transplants is unclear. METHOD To clarify the long-term outcomes of Japanese renal allograft recipients with HCV infections, we studied the cases of 187 patients (118 males and 69 females; 155 living donor cases, and 32 deceased donor cases; median follow-up period: 250 months) who underwent an initial renal transplant at Kanazawa Medical University from 1974 onwards. RESULT In this cohort, 35 patients (18.7%) were HCV core antigen (Ag)-positive, and 13 of them (37.1%) died (due to liver cirrhosis (4 cases), hepatocellular carcinoma (1 case), fibrosing cholestatic hepatitis due to HCV (1 case), and infections complicated with chronic hepatitis (6 cases)). However, only 14 of the 145 (9.7%) recipients died in the HCV-Ag/HCV antibody (Ab)-negative group. The Kaplan-Meier life table method indicated that the HCV-infected group exhibited significantly lower patient and death-censored allograft survival rates (log-rank test; patient survival: Chi-square: 11.2, p = 0.004; graft survival: Chi-square: 25.7, p < 0.001). The survival rate of the HCV-Ag-positive recipients decreased rapidly at 240 months after the renal transplant procedure. In addition, a Cox proportional hazards model indicated that positivity for the HCV-Ag was the most important independent risk factor for post-renal transplant survival and allograft function [survival: hazard ratio (HR) 3.93 (1.54-10.03), p = 0.004; graft function: HR 2.09 (1.14-3.81), p = 0.016]. CONCLUSION HCV infection is a harmful risk factor for patient survival (especially at ≥20 years post-renal transplant) and renal allograft function in allograft recipients.

Abstract
The prognostic factors and optimal therapy for invasive pulmonary aspergillosis (IPA) after kidney transplantation (KT) remain poorly studied. We included in this multinational retrospective study 112 recipients diagnosed with probable (75.0% of cases) or proven (25.0%) IPA between 2000 and 2013. The median interval from transplantation to diagnosis was 230 days. Cough, fever, and expectoration were the most common symptoms at presentation. Bilateral pulmonary involvement was observed in 63.6% of cases. Positivity rates for the galactomannan assay in serum and bronchoalveolar lavage samples were 61.3% and 57.1%, respectively. Aspergillus fumigatus was the most commonly identified species. Six- and 12-week survival rates were 68.8% and 60.7%, respectively, and 22.1% of survivors experienced graft loss. Occurrence of IPA within the first 6 months (hazard ratio [HR]: 2.29; p-value = 0.027) and bilateral involvement at diagnosis (HR: 3.00; p-value = 0.017) were independent predictors for 6-week all-cause mortality, whereas the initial use of a voriconazole-based regimen showed a protective effect (HR: 0.34; p-value = 0.007). The administration of antifungal combination therapy had no apparent impact on outcome. In conclusion, IPA entails a dismal prognosis among KT recipients. Maintaining a low clinical suspicion threshold is key to achieve a prompt diagnosis and to initiate voriconazole therapy.

Abstract
BACKGROUND Chronic hepatitis C patients in need of a lung transplant are often considered ineligible due to their infection. AIM To assess the association of hepatitis C virus (HCV) infection with long-term outcomes of lung transplants. METHODS From the Scientific Registry of Transplant Recipients (1995-2011), we selected all adults with and without HCV infection who underwent lung transplantation. RESULTS A total of 17 762 lung transplant recipients were included (55.5% bilateral). Of those, 319 (1.83%) had positive HCV serology. The HCV-positive recipients were 1.6 years younger, less Caucasian and more African-American, and had a significantly higher rate of co-infection with hepatitis B virus (all P < 0.001). Post-transplant patients were discharged alive at similar rates regardless of HCV status: 88.4% in HCV+ vs. 90.3% in HCV- (P = 0.25). The mortality rates were also similar at 1 and 2 years after transplantation (20.7% in HCV+ vs. 19.2% in HCV- and 31.6% in HCV+ vs. 28.9% in HCV-, respectively; both P > 0.05), but at post-transplant year 3 year, mortality rate in HCV+ became significantly higher (42.5% vs. 36.4%, P = 0.04) and remained higher for the duration of the follow-up (mean 9.1 years, max 18.4 years). In multivariate survival analysis, after adjustment for confounders, being HCV+ was associated with higher mortality: adjusted hazard ratio 1.24 (1.04-1.46), P = 0.01. No association of HCV infection with time to graft loss was found (P = 0.92). CONCLUSIONS Chronic HCV infection is associated with a moderate increase in post-lung transplant mortality. Treatment of HCV in lung transplant recipients may, therefore, result in improvement of post-transplant outcomes.

Abstract
Liver disease due to hepatitis C infection in renal transplant recipients is difficult to treat and often associated with reduced patient survival. A 43-year-old male, a renal allograft recipient, presented at 6 years follow-up with significant weight loss over 3 months. He was detected to have new onset diabetes mellitus together with hepatitis C virus (HCV) infection (genotype 1). His HCV load remained high despite the change of immuno-suppression from tacrolimus to cyclosporine. A decision to treat with a new anti-viral combination of ledipasvir and sofosbuvir for 12 weeks was taken. Within 3 weeks, his raised serum transaminases levels normalized and viral load became undetectable. At the end of 16 weeks, he continues to do well with normal renal function, has sustained remission from hepatitis C infection and resolution of diabetes.

Abstract
Nucleic acid testing (NAT) for hepatitis C virus (HCV) is recommended for screening of organ donors, yet not all donor infections may be detected. We describe three US clusters of HCV transmission from donors at increased risk for HCV infection. Donor's and recipients' medical records were reviewed. Newly infected recipients were interviewed. Donor-derived HCV infection was considered when infection was newly detected after transplantation in recipients of organs from increased risk donors. Stored donor sera and tissue samples were tested for HCV RNA with high-sensitivity quantitative PCR. Posttransplant and pretransplant recipient sera were tested for HCV RNA. Quasispecies analysis of hypervariable region-1 was used to establish genetic relatedness of recipient HCV variants. Each donor had evidence of injection drug use preceding death. Of 12 recipients, 8 were HCV-infected-6 were newly diagnosed posttransplant. HCV RNA was retrospectively detected in stored samples from donor immunologic tissue collected at organ procurement. Phylogenetic analysis showed two clusters of closely related HCV variants from recipients. These investigations identified the first known HCV transmissions from increased risk organ donors with negative NAT screening, indicating very recent donor infection. Recipient informed consent and posttransplant screening for blood-borne pathogens are essential when considering increased risk donors.

Abstract
BACKGROUND Research focused on identifying vulnerable populations and revealing specific risk factors for barriers along the pathway from ESRD to kidney transplantation has been mostly descriptive and the causes of existing disparities remain unclear. However, several socio-economic factors that are associated with the access to and the outcome of the kidney transplantation have been identified. SUMMARY While the presence of racial, gender, and geographic disparities is noted, we were interested mostly to describe potential socio-economic factors associated with and possibly responsible for the presence of such disparities. In this review we focused on five factors: education level, employment status, income, presence of substance addiction or abuse, and marital status. We describe the new method to quantify patients' socio-economic status and identify the group of high risk in terms of the transplant outcome, easily calculated social adaptability index, previously associated with clinical outcome in several patient populations including those with kidney transplant. At the end, based on literature analyzed we offer potential interventions that potentially can be used in order to reduce the degree of disparities. CONCLUSION Based on review of literature socio-economic factors are associated with and possibly responsible for healthcare disparities. Social adaptability index allows quantifying the degree of socio-economic status and identifying the group of high risk for inferior transplant outcome.

Abstract
Liver disease secondary to chronic hepatitis C virus (HCV) infection is an important cause of morbidity and mortality in patients with end-stage renal disease (ESRD) on renal replacement therapy and after kidney transplantation (KT). Hemodialytic treatment (HD) for ESRD constitutes a risk factor for bloodborne infections because of prolonged vascular access and the potential for exposure to infected patients and contaminated equipment. Evaluation of HCV-positive/ESRD and HCV-positive/KT patients is warranted to determine the stage of disease and the appropriateness of antiviral therapy, despite such treatment is challenging especially due to tolerability issues. Antiviral treatment with interferon (IFN) is contraindicated after transplantation due to the risk of rejection, and therefore, treatment is recommended before KT. Newer treatment strategies of direct-acting antiviral agents in combination are revolutionizing HCV therapy, as a result of encouraging outcomes streaming from recent studies which report increased sustained viral response, low or no resistance, and good safety profiles, including preservation of renal function. KT has been demonstrated to yield better outcomes with respect to remaining on HD although survival after KT is penalized by the presence of HCV infection with respect to HCV-negative transplant recipients. Therefore, an appropriate, comprehensive, easily applicable set of clinical practice management guidelines is necessary in both ESRD and KT patients with HCV infection and HCV-related liver disease.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is highly prevalent in renal transplant (RT) recipients. Currently, interferon-based (IFN-based) antiviral therapies are the standard approach to control HCV infection. In a post-transplantation setting, however, IFN-based therapies appear to have limited efficacy and their use remains controversial. The present study aimed to evaluate the efficacy and safety of IFN-based therapies for HCV infection post RT. METHODS We searched Pubmed, Embase, Web of Knowledge, and The Cochrane Library (1997-2013) for clinical trials in which transplant patients were given Interferon (IFN), pegylated interferon (PEG), interferon plus ribavirin (IFN-RIB), or pegylated interferon plus ribavirin (PEG-RIB). The Sustained Virological Response (SVR) and/or drop-out rates were the primary outcomes. Summary estimates were calculated using the random-effects model of DerSimonian and Laird, with heterogeneity and sensitivity analysis. RESULTS We identified 12 clinical trials (140 patients in total). The summary estimate for SVR rate, drop-out rate and graft rejection rate was 26.6% (95%CI, 15.0-38.1%), 21.1% (95% CI, 10.9-31.2%) and 4% (95%CI: 0.8%-7.1%), respectively. The overall SVR rate in PEG-based and standard IFN-based therapy was 40.6% (24/59) and 20.9% (17/81), respectively. The most frequent side-effect requiring discontinuation of treatment was graft dysfunction (14 cases, 45.1%). Meta-regression analysis showed the covariates included contribute to the heterogeneity in the SVR logit rate, but not in the drop-out logit rate. The sensitivity analyses by the random model yielded very similar results to the fixed-effects model. CONCLUSIONS IFN-based therapy for HCV infection post RT has poor efficacy and limited safety. PEG-based therapy is a more effective approach for treating HCV infection post-RT than standard IFN-based therapy. Future research is required to develop novel strategies to improve therapeutic efficacy and tolerability, and reduce the liver-related morbidity and mortality in this important patient population.

Abstract
Outcomes following renal and simultaneous kidney-pancreas transplants have improved significantly due to better surgical techniques and improved modalities of antirejection therapy. However, infection remains a significant cause of morbidity and mortality. The use of new modalities of immunosuppression and routine use of antimicrobial prophylaxis has changed the pattern of infections post-transplantation. Cytomegalovirus remains a significant problem and BK virus has emerged as an important pathogen. New antimicrobial agents are now available to treat infection, however, antimicrobial resistance remains a concern.

Abstract
BACKGROUND Advanced fibrosis or cirrhosis is still regarded as a contraindication for kidney transplantation alone by most centers. The value of aminotransferase to platelet ratio index (APRI) and other non-invasive markers has been less studied in hepatitis C virus (HCV)-positive patients with concurrent end-stage renal disease to predict hepatic fibrosis. Can these be used to effectively decrease the number of biopsies done in these patients being evaluated for transplantation? METHODS Our study population included 255 patients with liver biopsy data. All patient information was collected and reviewed from medical records. The diagnostic accuracy of the predictive models was analyzed by calculating sensitivity, specificity, positive predictive value and negative predictive value. RESULTS The variables associated with F3-F4 were aspartate aminotransferase (P = 0.007), bilirubin (P ≤ 0.001), platelet count (P = 0.01) and APRI (P ≤ 0.001). The use of any one laboratory abnormality to predict liver biopsy scores did not show high positive predictive values (22.6-72.7%). Having abnormal liver findings or cirrhosis on imaging was associated with high specificities (92.0-97.8%) but low sensitivities (31.4-42.9%). Using APRI levels of ≥0.40 and ≤0.95 as an indication for liver biopsy, 50% of patients with F3-F4 would have correctly avoided having a biopsy. However, 33% of patients with F3-F4 would have been mislabeled and not be indicated for biopsy. CONCLUSIONS Our data suggest that there may not currently be a simple and sufficiently accurate non-invasive test to replace liver biopsy in renal transplant workup for HCV-positive patients. The risks outweigh the benefits when it comes to using non-invasive markers like the APRI.

Abstract
: Hepatitis C virus (HCV) infection is common in solid organ allograft recipients and is a significant cause of morbidity and mortality after transplantation, so effective management will improve outcomes. In this review, we discuss the extent of the problem associated with HCV infection in donors and kidney, heart, and lung transplant candidates and recipients and recommend follow-up and treatment.Patients with end-stage kidney disease without cirrhosis and selected patients with early-stage cirrhosis can be considered for kidney transplant alone. In HCV-infected kidney allograft recipients, the progression of fibrosis should be evaluated serially by Fibroscan or serologic measures of fibrosis. Transplantation of kidneys from HCV-positive donors should be restricted to HCV-positive recipients as it is associated with a reduced time waiting for a graft and does not affect posttransplant outcomes. Hepatitis C virus antiviral therapy should be considered for all HCV-RNA-positive kidney transplant candidates, irrespective of the baseline liver histopathology. Protease inhibitors have yet to be fully evaluated in patients with renal dysfunction and in the transplant population. As these agents may cause anemia in patients with normal renal function, tolerability may be a problem in patients with end-stage kidney disease.The impact of HCV infection on survival in heart and lung transplantation is unclear. Because of the shortage of organs, few HCV-infected patients are accepted for transplantation.Universal use of nucleic acid amplification testing (NAT) for the screening of potential organ donors should be reserved to high-risk donors. Assays that quantify HCV core antigen may become more cost-effective than NAT for the screening of potential organ donors.

Abstract
BACKGROUND The clinical outcomes of hepatitis C infection in kidney transplantation and maintenance dialysis patients remain controversial. Here, we conducted a systematic review and meta-analysis that aimed at comparing 5-year mortality rates between waiting list and kidney transplantation patients with hepatitis C infections. METHODS We searched Medline, EMBASE, and Scopus databases published since inception to June 2011 and found nine studies with 1734 patients who were eligible for pooling. Eligible studies were cohort studies that analyzed adult end-stage renal disease patients with hepatitis C virus infection and compared death rates between waiting list and kidney transplantation. The crude risk ratio of death along with its 95% confidence interval was estimated for each study. Data were independently extracted by two reviewers. RESULTS The pooled risk ratio of death at 5 years by using a random-effect model was 2.19 (95% confidence interval, 1.50-3.20), which significantly favored the kidney transplantation when compared with the waiting list. There was evidence of heterogeneity of death rates across studies (χ(2) = 22.6; df = 8; P = 0.004). From the metaregression model, age and male gender could be the source of heterogeneity or variation of treatment effects. A major cause of death in the waiting list was cardiovascular diseases, whereas infection was a major cause in the transplant group. There was no evidence of publication bias suggested by an Egger test. CONCLUSIONS This systematic review suggested that hepatitis C virus-infected patients who remain on dialysis are at higher risk of death when compared with those who received kidney transplantations.

Abstract
BACKGROUND This study aims to identify crucial factors affecting the evolution of liver disease in HCV-infected renal transplant recipients. METHODS Forty-two HCV-infected recipients with known time of HCV acquisition were followed up for a mean (SD) of 7.6 ± 3.4 yr after transplantation with consecutive liver biopsies. Hepatitis progression was defined by: a) fibrosis progression ≥ 0.2 stages/yr and/or b) development of a cholestatic syndrome. RESULTS Twenty-three patients (54.8%) displayed benign and 19 (45.2%) aggressive hepatitis progression. Hepatitis course was aggressive in 9.1% and 85% of the patients infected pre- and peri/post-transplantation, respectively (p < 0.001). In multivariate analysis, patients who acquired HCV infection peri- or after transplantation had an increased risk of an adverse outcome compared with those infected before transplantation (p = 0.001). HCV RNA levels at the time of first liver biopsy were lower in patients showing a benign course compared with those with aggressive evolution (p = 0.052). CONCLUSIONS Time of acquisition of HCV infection is a major prognostic factor for hepatitis progression in the setting of renal transplantation. Immunosuppression was found to be determinant in the progression of HCV infection acquired peri- or post-transplantation. High viral load seems to be crucial in the pathogenetic process.

Abstract
Chronic kidney disease represents a global health problem. Chronic hepatitis C virus (HCV) infection is prevalent in patients with end stage renal disease (ESRD) on hemodialysis (HD) and in renal transplant recipients with significant impact on morbidity and mortality. Furthermore, HCV can cause various forms of glomerulopathy with the predominant type being cryglobulinemia associated membranoproliferative glomerulonephritis. Liver enzymes are traditionally used as markers of liver injury; however, there is wide variation in aminotransferase levels in patients with ESRD. Therefore, diagnosis of chronic hepatitis C (CHC) in patients with ESRD is based on HCV antibody testing and further confirmation with polymerase chain reaction testing. Current standard therapy for CHC is composed of pegylated interferon and ribavirin. However, this combination is challenging in patients with ESRD due to its tolerability. We describe in this review relevant issues in epidemiology, diagnosis and management of CHC in ESRD, HD and renal transplant recipients.

Abstract
Introduction. Hepatitis C virus (HCV) infection is an independent risk factor for renal transplantation (RTx). Immunosuppression minimization can render better quality of life to these patients. Methods. We analyzed 132 HCV-positive RTx patients (group A) transplanted under tolerance induction protocol (TIP) and compared them with 79 controls (group B) transplanted using standard triple drugs. TIP consisted of 1 donor-specific transfusion, peripheral blood stem cell infusion, portal infusion of bone marrow, and target-specific irradiation. Their immunosuppression was cyclosporin, 2 ± 1 mg/kg BW/day + prednisone, 10 mg/day. Results. TIP had no side effects. Although unequal in size, the groups were well balanced. Group A patient survival at 1, 5, and 10 years was 92.4%, 70.4%, and 63.7%, respectively, versus 75.6%, 71.7%, and 55.7% in later, and graft survival was 92.9%, 81.5%, and 79.1% versus 91.7%, 75.7%, and 67.7%, respectively. Mean serum creatinine (mg/dL) at these time periods in former was 1.38, 1.72, and 1.87, versus 1.3, 1.75, and 2.1 in later. Altered liver functions were noted in 22% patients in former versus 31% in later. Group A had lesser rejection episodes. Conclusion. RTx using TIP in HCV-positive patients is a viable option with acceptable outcome.

Abstract
Hepatitis C virus (HCV) infection is relatively common among patients with end-stage kidney disease (ESKD) on dialysis and kidney transplant recipients. HCV infection in hemodialysis patients is associated with an increased mortality due to liver cirrhosis and hepatocellular carcinoma. The severity of hepatitis C-related liver disease in kidney transplant candidates may predict patient and graft survival after transplant. Liver biopsy remains the gold standard in the assessment of liver fibrosis in this setting. Kidney transplantation, not haemodialysis, seems to be the best treatment for HCV+ve patients with ESKD. Transplantation of kidneys from HCV+ve donors restricted to HCV+ve recipients is safe and associated with a reduction in the waiting time. Simultaneous kidney/liver transplantation (SKL) should be considered for kidney transplant candidates with HCV-related decompensated cirrhosis. Treatment of HCV is more complex in hemodialysis patients, whereas treatment of HCV recurrence in SLK recipients appears effective and safe.

Abstract
Chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection in potential kidney transplant candidates-once considered absolute contraindications to kidney transplantation-no longer creates overt barriers to transplantation. Advances in the medical management of HBV and HCV infection have created opportunities for a substantial number of patients to be effectively treated with antiviral therapy before transplantation. For HBV infection, a number of new drugs enable clearance of the virus with minimal adverse effects and drug resistance. Pretransplantation antiviral therapy is advisable for patients with HCV infection, but adverse effects are common and viral eradication remains challenging. Regardless of viral clearance, pretransplant patients without bridging fibrosis (as confirmed by liver biopsy) or clinical stigmata of cirrhosis should be considered for kidney transplantation as survival is superior when compared to treatment with dialysis, and progression of liver disease is unlikely. For patients with advanced liver disease, simultaneous liver-kidney transplantation is an important consideration. These treatment advances further increase the burden of organ donor shortage; however, organs from deceased donors with chronic HBV or HCV infection could be efficiently allocated to certain individuals with a viral infection of the same type to increase the pool of available transplant organs.

Abstract
PURPOSE OF REVIEW Recurrent glomerulonephritis is the third most common cause of graft failure, ranking only behind immunologic rejection and death with a functioning graft. Knowledge of the rates and timing of recurrent glomerular disease are important in counseling potential transplant recipients and preventive and therapeutic treatment strategies are necessary for those patients at risk. RECENT FINDINGS Large observational studies that have analyzed posttransplant biopsies have confirmed the high rates of glomerular disease recurrence in renal allografts. Newer immunosuppressive protocols over the past 10 years have not affected the rate of disease recurrence or graft loss. There is emerging evidence that rituximab may be efficacious in treating recurrent membranous nephropathy and focal segmental glomerulosclerosis; however, larger clinical trials are warranted. SUMMARY Recurrent glomerulonephritis is an important determinant of long-term outcomes after transplantation, requiring appropriate counseling to potential transplant recipients. Currently, there are no proven strategies to prevent recurrent glomerulonephritis in renal transplant recipients. Despite the high rates of recurrent disease, long-term graft survival is still very good and transplantation remains the best treatment option for patients with end-stage renal disease from primary glomerulonephritis.

Abstract
BACKGROUND Preexisting hepatitis C virus (HCV) infection is implicated in diminished patient and graft survivals in renal transplant recipients. The impact of HCV infection on patient and graft survival in simultaneous pancreas-kidney transplantations is unclear. We evaluated the effect of preexisting HCV infection on patient and graft survival in simultaneous pancreas-kidney transplant (SPKT) recipients in the United States. METHODS Using the Organ Procurement and Transplant Network/United Network for Organ Sharing database as of March 2009, adult primary SPKT recipients transplanted from 1995 to 2008 were studied. We stratified recipients based on pretransplant HCV status as HCV positive (HCV+) or HCV negative (HCV-). Overall kidney graft, pancreas graft, and patient survival were compared. RESULTS A total of 10,809 adults received primary SPKT, of which 350 (3.2%) were HCV+. Less than 2% of the HCV+ recipients received organs from HCV+ donors. There were no significant differences in baseline donor and recipient characteristics between groups. Rates of acute kidney rejection at 1 year were similar: 22.9% for HCV+ and 23.0% for HCV- recipients (P=0.49). There was no difference in serum creatinine between groups up to 3 years. After controlling for confounding factors, HCV positivity was not associated with worsened overall kidney graft (hazard ratio [HR] 0.80, 95% confidence interval [CI] 0.61-1.03), pancreas graft (HR 0.80, 95% CI 0.63-1.00), or patient survival (HR 0.78, 95% CI 0.56-1.08). CONCLUSIONS Only 3.2% of SPKT recipients had preexisting HCV infection. Preexisting HCV infection had no significant impact on kidney graft, pancreas graft, or patient survival.

Abstract
Hepatitis C virus (HCV) infection remains frequent among renal transplant (RT) recipients and has a detrimental effect on patient and graft survival. accelerated progression of liver disease due to HCV has been implicated in increased mortality after kidney transplantation but additional outcomes have been related to HCV after RT. all HCV-infected kidney transplant candidates should be considered for liver biopsy before RT. HCV infection should not be considered an absolute contraindication to renal transplantation, although the course of HCV-related liver disease is often progressive. Numerous organ procurement organizations have introduced the policy of accepting kidneys from HCV-positive donors for HCV-positive recipients, but this is still controversial. Single-center experiences have not reported adverse effects on the short-term patient and graft survival, however information from large databases has suggested that RT recipients of HCV-positive donors are independently at risk of mortality even in the modern era of immunosuppression. Renal transplantation should be considered using HCV-seropositive grafts for qualified patients with chronic kidney disease (CKD) stage 5 and HCV infection since good information indicates that the transplantation of kidneys from HCV-infected donors results in improved survival compared to wait-listed and dialysis-dependent candidates. a potential risk related to the use of donor HCV-positive kidneys cannot be excluded, and kidneys from HCV-infected donors should be restricted to recipients with evidence of active viremia at the time of kidney transplantation.

Abstract
BACKGROUND The aim of this study was to compare the clinical and histopathological course of HCV infection acquired before and during or after renal transplantation. METHODS According to HCV status, 197 RT patients were divided into three groups. At the time of RT, anti-HCV antibody was positive in 47 patients (pre-RT HCV group). In 27 patients, in whom anti-HCV negative at the time of RT, anti-HCV and/or HCV RNA was found to be positive following an ALT elevation episode after RT (post-RT HCV group). Both anti-HCV and HCV RNA were negative at all times in remaining 123 patients (control group). RESULTS Liver biopsy was performed in 31 of 47 patients in pre-RT and 24 of 27 in post-RT HCV group after RT. Duration of follow-up was similar in all groups with a mean of 7.1 +/- 4.0 yr. Ascites and encephalopathy were seen in only post-RT HCV group (22%). Histological grade (6.5 +/- 2.7 vs. 4.1 +/- 1.4) and stage (2.0 +/- 1.5 vs. 0.8 +/- 0.8) was significantly severe in post-RT HCV group (p < 0.01). Three patients died due to liver failure in post-RT HCV group. CONCLUSIONS HCV infection acquired during or after RT shows a severe and rapidly progressive clinicopathological course, which is significantly different from pre-transplant anti-HCV positive patients.

Abstract
Chronic liver disease has a significant impact on the survival of renal transplant recipients with an incidence rate of 4-38%. Approximately, 8-28% of renal transplant recipients die due to chronic liver disease. Hepatitis C seems to be the leading cause of chronic liver disease in kidney recipients. Hepatitis C virus (HCV) infection has a wide range of prevalence (2.6-66%) among renal transplant recipients living in different countries with great genotype diversity in different parts of the world. Nowadays, antiviral drugs are used for the management of hepatitis C. Because of graft-threatening effects of some antiviral drugs used in HCV-infected renal transplant recipients, we specifically focused on HCV treatment after renal transplantation. Treatment of post-renal transplantation chronic liver disease with INF and ribavirin remains controversial. Anecdotal reports on post-renal transplantation hepatitis C demonstrate encouraging findings. This review summarises the most current information on diagnosis, treatment, prognosis, complications as well as the new aspects of treatment in HCV-infected renal transplant recipients. HCV belongs to the family of Flaviviridae, genus Hepacivirus.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is common among end-stage renal disease patients receiving hemodialysis and a kidney transplant. HCV-positive kidney transplant recipients have worse clinical outcomes than those who are HCV negative. The optimal immunosuppressive regimen in this group of patients remains uncertain. METHODS Using data obtained from the Organ Procurement and Transplantation Network/Scientific Registry of Transplant Recipients, we studied the impact of induction and maintenance immunosuppression on risk of patient death, with death-censored graft failure and death with a functioning graft as secondary endpoints. Cox regression analysis was used to estimate hazard ratios (HR) adjusted for donor, recipient, and transplant variables. A total of 3708 HCV-positive and 75,629 HCV-negative kidney transplant recipients were analyzed. RESULTS Patient survival was negatively affected by HCV-positive serology. Among HCV-positive kidney transplant recipients, a reduced HR for patient death was observed with the use of induction therapy (HR=0.75, 95% CI 0.61-0.90, P=0.003) and with the use of mycophenolate mofetil (HR=0.77, 95% CI 0.64-0.92, P=0.005). CONCLUSIONS In kidney transplant recipients with HCV-positive serology, the use of antibody induction did not negatively affect patient survival and the use of mycophenolate mofetil as part of maintenance immunosuppression was associated with better patient survival.

Abstract
BACKGROUND Liver disease has emerged as an important cause of morbidity and mortality in renal transplant recipients. Liver insufficiency is the cause of death in up to 28% of long-term survivors after renal transplantation. The aim of this work was to evaluate the prevalence and causes of hepatic dysfunction in renal transplant recipients in Egypt, and its impact on both renal graft function and patient survival. METHODS This study comprised 447 kidney transplant recipients who received their grafts between January 1999 and December 2003 at Mansoura Urology and Nephrology Center. Among these recipients, 104 patients showed persistent hepatic dysfunction, while the remaining 343 had normal liver function or transient hepatic dysfunction of less than 6 months' duration. RESULTS We found that the prevalence of persistent hepatic dysfunction in our recipients was 23.3%. Infections such as hepatitis C virus (HCV;, with longer dialysis duration and blood transfusion as risk factors), HBV, and cytomegalovirus (CMV), were the main causes of persistent hepatic dysfunction. Drugs (e.g., the sirolimus and tacrolimus; cyclosporine; and azathioprine) were also associated with hepatic dysfunction. We did not find a significant impact of hepatic dysfunction on either patient or graft survival. CONCLUSIONS Viral infections-especially HCV and CMV-were more prevalent in the group of patients with persistent hepatic dysfunction, with duration of dialysis as an important risk factor for HCV infection. Dose-dependent cyclosporine-induced hepatic dysfunction was observed early post-transplant. Neither tacrolimus- nor sirolimus-associated hepatic dysfunction was dose-dependent. Hepatic dysfunction had no significant impact on either patient or graft survival; however, this finding may be due to the relatively short duration of follow up.

Abstract
BACKGROUND Standard treatment of chronic hepatitis C virus (HCV) infection based on interferon is not an option in renal transplant recipients due to the high risk of acute allograft rejection. OBJECTIVES To assess efficacy and tolerability of combined treatment with ribavirin and amantadine regarding viral clearance, normalization of liver enzymes, and improvement of HCV-related hepatopathy and graft nephropathy in HCV-RNA-positive renal transplant patients. STUDY DESIGN Prospective randomized controlled study comparing ribavirin, 1000 mg daily (n=7), versus ribavirin, 1000 mg, in combination with amantadine, 200 mg daily (n=8), for 12 months, versus no therapy (controls, n=26). Results were evaluated by intention-to-treat analysis. RESULTS No relevant differences among treatment groups were found regarding liver enzymes, HCV viremia, liver histology and renal parameters. However, antiviral treatment was limited by anemia, resulting in premature withdrawal from therapy and requiring substitution with recombinant erythropoietin in most patients. The best predictor for tolerability of active treatment was a creatinine clearance rate>50 ml/min. CONCLUSIONS Addition of amantadine to ribavirin seems not to be superior to ribavirin monotherapy in renal transplant patients with chronic replicating HCV infection. However, this may be explained in part by the poor tolerability of both ribavirin and amantadine in patients with impaired renal function, resulting in drop-outs and subtherapeutic drug dosage.

Abstract
The prevalence of hepatitis C virus infection among patients on hemodialysis is about ten times higher than in the normal population. The infection can induce chronic glomerulonephritis, as an extrahepatic manifestation, which can lead to end stage renal disease. However, in the majority of the patients hepatitis C virus is acquired as a nosocomial infection during the hemodialysis. In most of the infected patients the liver enzymes are usually normal and need regular screening of the hepatitis C antibody to detect the infection. Despite of the normal liver enzymes, the liver disease may progress to cirrhosis. A part of the patients wait for renal transplantation. The immunosuppressive treatment after the renal transplantation results in a significantly increased viral replication which might induce further progression of the liver disease. Interferon treatment given after the transplantation can induce rejection and graft failure. Therefore the antiviral treatment should be administered during the hemodialysis or earlier. Only limited data are available with the treatment of patients with impaired renal function. Mostly alfa-interferon was used in these patients. Due to the impaired renal clearance and higher serum concentration interferon seems to be more effective, but less tolerable in patients with end stage renal disease than in normal patients. Ribavirin is also excreted exclusively by the kidney and the anemia is even more pronounced in these patients, therefore it is contraindicated in patients on hemodialysis. The pharmacokinetics of the pegylated interferon alfa-2a is very advantageous for the patients with end stage renal disease. The safety and efficacy of peginterferon alfa-2a is now being confirmed in many publications.

Abstract
Postrenal transplant hepatitis C is increasing in frequency due to the high prevalence of hepatitis C among patients with renal failure. Despite this, there is still no standard hepatitis C treatment available for renal transplanted recipients. Combination antiviral hepatitis C therapy, the standard of care in the nontransplant population, is generally avoided because of documented renal graft rejection secondary to interferon treatment. A case of a male patient with postrenal transplant hepatitis C, which was associated with cryoglobulinemia and glomerulonephritis of the graft, is presented. He was treated with standard interferon with ribavirin. Sustained viral clearance was achieved despite ongoing evidence of cryoglobulinemia. Renal function, which had been deteriorating before treatment, improved as evidenced by the stabilization of serum creatinine and marked improvement of proteinuria. In conclusion, in selected patients, combination antiviral therapy may still be a viable option postrenal transplant.

Abstract
BACKGROUND Chronic hepatitis C virus (HCV) infection is a common cause of liver disease in post-renal transplant period and causes poor patient and graft survival. We analyzed the effects of antiviral therapy using ribavirin monotherapy or ribavirin in combination with interferon (IFN)-alpha in our kidney transplant recipients with chronic hepatitis C. METHODS Total of 14 patients received antiviral therapy, all of whom had stable graft function, raised aminotransferases and positive HCV viremia at the start of treatment. Eight patients received ribavirin alone for a period of six months to two yr, in doses of 400-800 mg daily. Five patients received IFN-alpha therapy for a period of two months to 1.5 yr, in doses of 1.5 million units daily or three million units thrice weekly with ribavirin. One patient received pegylated IFN 50 microg once weekly in combination with ribavirin. The response was seen in terms of biochemical and virological improvement at the end of study period. RESULTS In patients treated with ribavirin alone (n = 8), mean alanine aminotransferase (ALT) levels before and after treatment were significantly different (198.4 +/- 147.6 and 104.8 +/- 66.5 IU/L respectively; p < 0.05). ALT levels normalized completely in three patients at the end of treatment, improved in three patients and deteriorated in two. Only in one of eight patients on ribavirin alone, HCV-RNA became negative after six months of treatment while in the rest (n = 7) HCV-RNA continued to be positive. In subjects on IFN plus ribavirin (n = 6), the mean ALT levels decreased significantly (from 280.2 +/- 114.9 IU/L at baseline to 71 +/- 49 IU/L at end of therapy; p < 0.05). Two patients had sustained remission (33.3%) on IFN plus ribavirin (persistently negative HCV-RNA), two patients relapsed after initial remission and in two patients treatment was stopped after two months because of graft dysfunction. Totally four patients developed graft dysfunction at some time during the course of IFN therapy (66.6%), but it was discontinued in only two (33.3%). All patients regained normal creatinine levels after discontinuation of IFN, although one patient developed chronic allograft nephropathy as shown by kidney biopsy. Four patients in IFN group developed leucopenia. Two patients developed severe anemia one of whom required blood transfusion and one developed severe flu-like syndrome requiring stoppage of therapy. CONCLUSION Ribavirin monotherapy in renal transplant recipients with chronic hepatitis C infection results in good biochemical response but is not associated with virological clearance. IFN in combination with ribavirin is effective in two-thirds of patients after a minimum therapy of six months, but it is poorly tolerated, results in graft dysfunction in significant number of patients, and relapse can occur after stopping treatment.

Abstract
Data concerning the effect of hepatitis C virus (HCV) infection on the long-term outcome of patient and allograft survival are conflicting. We performed a retrospective study including all renal transplant recipients who underwent the procedure at our center between July 1983 and December 2004. We compared HCV-positive (n = 155) versus HCV-negative (n = 1044) recipients for the prevalence of anti-HCV, patient/donor characteristics, and graft/patient survival. The prevalence of HCV-positive patients was 12%. The anti-HCV positive recipients displayed a longer time on dialysis (P < .001), more blood transfusions prior to transplant (P < .001), and a higher number of previous transplants (P < .001). There were no differences in the incidence of acute rejection between the two groups. Patient (P = .006) and graft survival (P = .012) were significantly lower in the HCV-positive than the HCV-negative group. Graft survival censored for patient death with a functioning kidney did not differ significantly between HCV-positive and HCV-negative recipients (P = .083). Death from infectious causes was significantly higher among the HCV-positive group (P = .014). We concluded that HCV infection had a significant detrimental impact on patient and renal allograft prognosis. Death from infectious causes was significantly more frequent among HCV-positive than the non-HCV population.

Abstract
BACKGROUND The aim of this study is to evaluate the natural course of hepatitis C virus (HCV) infection in renal transplant recipients infected shortly before or after renal transplantation. METHODS Seventeen renal transplant recipients with no detectable antibodies to HCV before renal transplantation either seroconverted after transplantation or developed cholestatic syndrome without seroconversion, but with HCV RNA positivity. They were followed up for a mean of 7.2 +/- 4.2 (SD) years after renal transplantation and underwent consecutive liver biopsies. RESULTS Biochemical abnormalities initially were observed a median of 5.7 months (25th, 75th percentiles, 2.4, 13.9) after transplantation. Initial liver biopsies showed acute hepatitis in 5 patients and chronic hepatitis in 9 patients, whereas 3 patients had histological findings of fibrosing cholestatic hepatitis. During a median follow-up of 2.0 years (25th, 75th percentiles, 1.3, 4.6), the condition of 5 patients, initially with diagnoses of acute hepatitis, deteriorated rapidly, with a median fibrosis progression rate of 0.77 (25th, 75th percentiles, 0.56, 0.86) per year. Six patients with chronic hepatitis progressed with a median fibrosis progression rate of 0.35 (25th, 75th percentiles, 0.15, 0.69) per year in a median of 3.1 years (25th, 75th percentiles, 2.4, 3.5), whereas the other 3 patients with chronic hepatitis with elevated cholestatic liver enzyme levels developed early fibrosing cholestatic hepatitis (1 patient) or vanishing bile duct syndrome (2 patients). Genotype 1 was found in 7 of 9 patients with fibrosing cholestatic hepatitis or vanishing bile duct syndrome (78%; P = 0.049). Six of 17 patients died a median of 6.1 years (25th, 75th percentiles, 1.5, 7.1) posttransplantation; 4 of these 6 patients died of hepatic failure. CONCLUSION HCV infection acquired shortly before or after renal transplantation frequently is associated with an adverse clinical outcome, characterized by rapid progression of fibrosis, development of cholestatic syndrome, and high mortality rate. Acute hepatitis occurring under maximal immunosuppression is of great prognostic significance, determining a specific high-risk group.

Abstract
INTRODUCTION Renal transplant (RTx) patients with hepatitis C frequently show normal levels of alanine aminotransferase (ALT) and the significance of ALT in this group has not been established. AIM To determine the value of ALT as a marker of histologic hepatic damage in RTx patients with hepatitis C virus (HCV) infection. MATERIALS AND METHODS HCV-RNA-positive RTx patients with a liver biopsy were analyzed regarding staging and the grading of periportal and lobular necroinflammatory activity. Spearman's correlation coefficient was used to determine the correlation between ALT and histologic variables. Sensitivity, specificity and positive and negative predictive values (PPV and NPV) of ALT in the detection of septal fibrosis and interface hepatitis, and/or confluent necrosis were calculated. RESULTS Fifty-three patients (32 men, 60%), with a mean age of 42 +/- 10 yr and time since transplant of 5 +/- 4 yr were included. Only 27 (51%) patients showed elevated ALT levels, which were associated with septal fibrosis (p = 0.001), interface hepatitis (p < 0.001) and confluent necrosis (p = 0.05). A correlation was observed between ALT and staging (r = 0.50, p < 0.001), periportal necroinflammatory activity (r = 0.59, p < 0.001) and lobular necroinflammatory activity (r = 0.50, p < 0.001). The sensitivity, specificity, PPV and NPV of ALT were 92, 61, 41 and 96%, respectively, for the detection of septal fibrosis, and 87, 77, 74 and 88% for the detection of interface hepatitis and/or confluent necrosis. CONCLUSION ALT is a good marker of histologic hepatic lesion in HCV-infected RTx patients and, therefore, liver biopsy can be avoided in patients with persistently normal ALT.

Abstract
BACKGROUND The shortage of organ donors for kidney transplants has made the expansion of the kidney donor pool a clinically significant issue. Previous studies suggest that kidneys from donors with a history of intravenous (IV) drug, cigarette, and/or alcohol use are considered to be a risky choice. However, these kidneys could potentially be used and expand the kidney supply pool if no evidence shows their association with adverse transplant outcomes. METHODS This study analyzed the United Network for Organ Sharing dataset from 1994 to 1999 using Kaplan-Meier survival analysis and Cox modeling. The effects on transplant outcome (graft and recipient survival) were examined with respect to the donors' IV drug use, cigarette smoking, and alcohol dependency. Covariates including the recipient variables, the donor variables, and the transplant procedure variables were included in the Cox models. RESULTS The results show that the donors' history of cigarette smoking is a statistically significant risk factor for both graft survival (hazard ratio=1.05, P<0.05) and recipient survival (1.06, P<0.05), whereas neither IV drug use nor alcohol dependency had significant adverse impact on graft or recipient survival. CONCLUSIONS Assuming that adequate testing for potential infections is performed, there is no evidence to support avoiding the kidneys from donors with IV drug use or alcohol dependency in transplantation. Utilizing these kidneys would clearly expand the potential pool of donor organs.

Abstract
From 1992 to 2001 hepatitis C virus (HCV) viremia was studied in 53 renal transplant recipients anti-HCV+ with at least 3 months follow-up posttransplant using a quantitative retrotranscriptase-PCR method. HCV-RNA was detected in 45 (85%): 29 of the 34 recipients treated with azathioprine-based therapy and 15 of 18 treated with mycophenolate mofetil. Immunosuppressive therapy type did not affect HCV replication. Three different patterns of HCV-RNA evolution were detected: 13 (28.8%) patients with high RNA-HCV levels; 21 (46.7%) patients with low levels; and 11 (24.4%) patients with viremia elevation. In 10 (90%) of 11 of the last group, HCV viremia was detected before 15 days posttransplantation, significantly earlier than in the other two groups. Thus, replication during the first 15 days after transplantation leads to a high RNA-HCV viral load. No clinical symptoms were related to HCV.

Abstract
BACKGROUND The long-term outcome of kidney transplantation could be influenced by the appearance of antibodies against donor-specific antigens. Glutathione S-transferase T1 (GSTT1) is a protein preferentially expressed in liver and kidney cells. Deletion of the GSTT1 gene results in a complete lack of protein expression, which occurs in 20% of the white population. GSTT1 donor-recipient mismatch has been deleterious in liver transplantation. The purpose of this study is to examine immunologic and clinical consequences of a GSTT1 donor-recipient mismatch in kidney transplantation. METHODS The presence of anti-GSTT1 antibodies was studied retrospectively in sera from 135 patients who underwent transplantation before 1995. Samples from 89 patients who received a GSTT1-positive kidney graft between December 1998 and May 2001 were collected prospectively. GSTT1 genotypes and anti-GSTT1 antibodies were studied by using standard methods. RESULTS Seven patients, all with the null genotype, produced anti-GSTT1 antibodies. No transplant recipient with a positive genotype produced these antibodies. Six of 7 patients with antibodies also were positive for hepatitis C virus. Clinical outcomes of these patients did not differ from those of the entire group. CONCLUSION After kidney transplantation, some patients with the null GSTT1 genotype who received a GSTT1-positive graft developed an immune response, with production of anti-GSTT1 antibodies. The presence of these antibodies did not seem to produce functional impairment in the graft. Hepatitis C virus seems to have a prominent role in this particular allograft immune response.
