HCV-positive kidney transplant patients treated with direct-acting antivirals maintain stable medium-term graft function despite persistent reduction in tacrolimus trough levels. Ther Adv Chronic Dis 2022; 13:20406223221117975. [PMID: 36147292 PMCID: PMC9486264 DOI: 10.1177/20406223221117975] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2022] [Accepted: 07/19/2022] [Indexed: 11/16/2022] Open
Abstract
Background/aim: Direct-acting antivirals (DAAs) have improved the treatment of HCV-positive
kidney transplant recipients (KTRs). However, their medium-term follow-up
effects on graft function are conflicting. This study aimed to analyze how
the interplay between DAAs, calcineurin inhibitors (CNI), and HCV
eradication impacts 12-month kidney graft function. Methods: This double-center retrospective study with a prospective follow-up enrolled
35 KTRs with HCV treated with DAAs for 12 weeks. We compared three
parameters: estimated glomerular filtration rate (eGFR), 24-h proteinuria,
and CNI trough levels at three time points: baseline, end of treatment
(EOT), and 12 months later. Results: Kidney allograft function remained stable when comparing baseline and
12-month post-treatment values of eGFR (60.7 versus
57.8 ml/min; p = 0.28) and 24-h proteinuria (0.3
versus 0.2 g/24 h; p = 0.15), while
tacrolimus (Tac) trough levels underwent a statistically significant decline
(6.9 versus 5.4 ng/ml; p = 0.004). Using
an ongoing triple Tac-based maintenance therapy as a conservative measure, a
dose escalation of Tac was applied only in seven patients. No variation in
CyA and mTOR levels was detected. Conclusion: DAA therapy is safe and effective in HCV-positive KTRs. It also produces a
persistent significant reduction in Tac trough levels that does not
influence graft function at 12 months.

Abstract
Hepatitis C virus (HCV) is associated with increased mortality and morbidity in patients with chronic kidney disease (CKD). The early detection and treatment of Hepatitis C associated with kidney disease is paramount to preventing the progressive loss of kidney function. HCV treatment until the advent of direct acting anti-viral agents (DAAs) was limited to interferon and ribavirin. Interferon and ribavirin treatment resulted in only modest success but with frequent adverse events and poor tolerability. Furthermore, interferon and ribavirin could not be used in certain patient populations including those with advanced CKD, were on dialysis, or those who have received a kidney transplant. DAAs have now made treatment possible in these sub-groups with a sustained viral response (SVR) of 90-100% and minimal side effects. DAAs have helped increase transplant rates by allowing for the use of HCV positive kidneys in recipients who are HCV negative. Although the choice of DAAs should be carefully considered and based on patient characteristics, concomitant medications, and HCV genotype.

Abstract
UNLABELLED This article has been corrected. The original version (PDF) is appended to this article as a Supplement. DESCRIPTION The Kidney Disease: Improving Global Outcomes (KDIGO) 2018 clinical practice guideline for the prevention, diagnosis, evaluation, and treatment of hepatitis C virus (HCV) infection in chronic kidney disease (CKD) is an extensive update of KDIGO's 2008 guideline on HCV infection in CKD. This update reflects the major advances since the introduction of direct-acting antivirals (DAAs) in the management of HCV infection in the CKD population. METHODS The KDIGO work group tasked with developing the HCV and CKD guideline defined the scope of the guideline, gathered evidence, determined topics for systematic review, and graded the quality of evidence previously summarized by the evidence review team. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach was used to appraise the quality of evidence and rate the strength of the recommendations. Searches of the English-language literature were conducted through May 2017 and were supplemented with targeted searches for studies of DAA treatment and with abstracts from nephrology, hepatology, and transplantation conferences. A review process involving many stakeholders, subject matter experts, and industry and national organizations informed the guideline's final modification. RECOMMENDATION The updated guideline comprises 66 recommendations. This synopsis focuses on 32 key recommendations pertinent to the prevention, diagnosis, treatment, and management of HCV infection in adult CKD populations.

Abstract
Hepatitis C virus (HCV) infection unfavorably affects the survival of both renal patients undergoing hemodialysis and renal transplant recipients. In this subset of patients, the effectiveness and safety of different combinations of interferon-free direct-acting antiviral agents (DAAs) have been analyzed in several small studies. Despite fragmentary, the available data demonstrate that DAA treatment is safe and effective in eradicating HCV infection, with a sustained virologic response (SVR) rates nearly 95% and without an increased risk of allograft rejection. This review article analyzes the results of most published studies on this topic to favor more in-depth knowledge of the readers on the subject. We suggest, however, perseverating in this update as the optimal DAA regimen may not be proposed yet, because of the expected arrival of newer DAAs and of the lack of data from large multicenter randomized controlled trials.

Abstract
BACKGROUND Direct-acing antiviral agents are highly efficient treatment options for chronic hepatitis C virus (HCV) infection after renal allograft transplantation. Treatment options for patients with impaired graft function remain limited. Therefore, we assessed the effectiveness and safety of grazoprevir/elbasvir therapy for patients with chronic HCV infection and impaired renal allograft function. METHODS Eleven renal allograft recipients with therapy-naïve HCV genotype (GT) 1a, 1b, or 4 were treated with the fixed-dose combination of elbasvir/grazoprevir without ribavirin for 12 weeks. All recipients exhibited impaired graft function with an average glomerular filtration rate lower than 30 mL/min per 1.73 m2. Clinical data were retrospectively reviewed for renal and liver function parameters. Patients were closely monitored for trough levels of immunosuppressive agents, viral load, laboratory values, and potential adverse effects. RESULTS Seven (64%) patients exhibited a rapid virologic response within 4 weeks (HCV GT1a, n = 2; HCV GT1b, n = 5). The other 4 patients exhibited a virologic response within 8 weeks (HCV GT1b, n = 3; HCV GT 4, n = 1). All patients exhibited a sustained virologic response at week 12 after the end of treatment. Clinical measures of liver function improved substantially for all patients. Few adverse effects were reported. Impaired renal allograft function and proteinuria remained stable. For most patients, only moderate adjustments to the tacrolimus dosage were necessary for maintaining sufficient trough levels. CONCLUSIONS This treatment appears to be safe and effective for renal transplant recipients with impaired allograft function and is a promising treatment option for eradicating HCV infection in this patient population.

Abstract
KDIGO recently updated its clinical practice guideline for the prevention, diagnosis, evaluation, and treatment of hepatitis C virus (HCV) infection in patients with chronic kidney disease (CKD). The management of HCV in patients with CKD has dramatically shifted over the past 10 years with the development of direct-acting antiviral (DAA) agents and subsequent demonstration of their efficacy in CKD populations. The opportunity to cure HCV with DAA treatment has impacted all aspects of the KDIGO guideline on HCV in CKD including: (a) HCV diagnosis in CKD populations; (b) HCV treatment in CKD populations; (c) preventing HCV transmission in HD units; (d) management of HCV before and after kidney transplantation; and (e) management of HCV-associated glomerular disease. This review summarizes and discusses the major recommendations, along with the implication of the guideline on clinical practice.

Abstract
AIMS The data regarding the treatment of chronic hepatitis C (CHC) in renal transplant recipients is lacking from the Asia-Pacific region. The aim of the present study was to assess the safety and efficacy of directly acting antivirals (DAAs) in the treatment of CHC infection in renal transplant recipients. METHODS A total of 47 CHC infected renal transplant recipients were enrolled in this real life observational cohort analysis between March 2015 and September 2016. Presence of hepatic fibrosis/cirrhosis was assessed on transient elastography (Fibroscan). Fourteen patients were treated with Sofosbuvir and Ribavirin for 24 weeks. Twenty-two patients received Sofosbuvir and Ledipasvir and 12 patients received Sofosbuvir and Daclatasvir with (n = 3) or without (n = 31) Ribavirin for 12 or 24 weeks depending on genotype and underlying cirrhosis. Data were analyzed for safety and treatment efficacy [sustained virological response at 12 weeks (SVR12)]. RESULTS The median baseline HCV RNA concentration in the whole group was 7.38 × 106 IU/mL (1.23 × 104 -6.36 × 107 ). The SVR12 rates were 100% in all groups except in the Sofosbuvir and Ribavirin group (86%). Transient Elastography revealed minimal or no fibrosis (F0-F1) in 31 (65.96%) patients, moderate fibrosis (F2) in 11 (23.4%) patients and cirrhosis in five (10.64%) patients. The only serious adverse effect was anaemia observed in eight (57%) patients in the Sofosbuvir and Ribavirin group. CONCLUSION DAAs including Sofosbuvir, Daclatasvir and Ledipasvir with or without ribavirin are safe and effective for the treatment of chronic hepatitis C in renal transplant recipients.

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.

Recommendations for the treatment of hepatitis C virus infection in chronic kidney disease: a position statement by the Spanish association of the liver and the kidney. J Nephrol 2017; 31:1-13.

Abstract
Hepatitis C virus (HCV) infection is one of the main causes of liver cirrhosis worldwide. The long-term impact of HCV infection is highly variable, ranging from minimal histological changes to extensive fibrosis with hepatocellular carcinoma. The development of HCV drugs has increased dramatically in recent years, even in special populations such as chronic kidney disease patients. Classical treatment of chronic hepatitis C was based on the administration of interferon and ribavirin for 24-48 weeks, which was associated with a poor viral response and a high rate of side effects, especially in patients with a lower estimated glomerular filtration rate. The current high availability of the new direct-acting antivirals renders the classification of these agents for this special population necessary. The Spanish Association of the Liver and the Kidney has produced a position statement on the treatment of HCV infection in chronic kidney disease patients since the evidence to guide this treatment is scant and what evidence does exist is weak. The recommendations are based on the results of clinical trials and controlled studies conducted to date, with data published hitherto by the authors of these studies. Since the indications for treatment have been evaluated by other societies or are dependent on internal clinical protocols, the main goal of this position statement is to assist in decision-making when choosing a therapeutic option.

Abstract
BACKGROUND Treatment of chronic hepatitis C virus (HCV) infection after renal allograft transplantation has been an obstacle because of contraindications associated with IFN-based therapies. Direct-acting antiviral agents are highly efficient treatment options that do not require IFN and may not require ribavirin. Therefore, we assessed the efficacy and safety of sofosbuvir and ledipasvir in renal transplant patients with chronic HCV infection. METHODS Fifteen renal allograft recipients with therapy-naive HCV genotype (GT) 1a, 1b, or 4 were treated with the combination of sofosbuvir and ledipasvir without ribavirin for 8 or 12 weeks. Clinical data were retrospectively analyzed for viral kinetics and for renal and liver function parameters. Patients were closely monitored for trough levels of immunosuppressive agents, laboratory values, and potential adverse effects. RESULTS Ten patients (66%) exhibited a rapid virologic response within 4 weeks (HCV GT1a, n = 4; HCV GT1b, n = 6). The other 5 patients exhibited a virologic response within 8 (HCV GT 1b, n = 4) or 12 weeks (HCV GT4, n = 1). One hundred percent of patients exhibited sustained virologic response at week 12 after the end of treatment. Clinical measures of liver function improved substantially for all patients. Adverse events were scarce; renal transplant function and proteinuria remained stable. Importantly, dose adjustments for tacrolimus were necessary for maintaining sufficient trough levels. CONCLUSIONS The described regimen appears to be safe and effective for patients after renal transplant and is a promising treatment regimen for eradicating HCV in this patient population.

Abstract
BACKGROUND The efficacy and safety of direct-acting antivirals (DAAs) for treating hepatitis C virus (HCV)-infected renal transplant recipients (RTRs) has not been determined. METHODS We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials and assessed the quality of eligible studies using the Joanna Briggs Institute scale. DAA efficacy and safety were assessed using standard mean difference (SMD) with 95% confidence intervals (95%CIs). RESULTS Six studies (360 RTRs) were included. Two hundred thirty six RTRs (98.3%) achieved sustained virological response within 12 weeks; HCV infection was cleared in 239 RTRs after 24-week treatment. Liver function differed significantly pre- and posttreatment (alanine aminotransferase, SMD: 0.96, 95%CIs: 0.65, 1.26; aspartate aminotransferase, SMD: 0.89, 95%CIs: 0.60, 1.18); allograft function pre- and posttreatment was not statistically different (serum creatinine, SMD: -0.13, 95%CIs: -0.38, 0.12; estimated glomerular filtration rate, SMD: 0.20, 95%CIs: -0.11, 0.51). General symptoms (fatigue nausea dizziness or headache) were the most common adverse events (AEs) (39.3%). Severe AEs, that is, anemia, portal vein thrombosis, and streptococcus bacteraemia and pneumonia, were present in 1.1%, 0.6%, and 1.1% of RTRs, respectively. CONCLUSION Our findings suggest that DAAs are highly efficacious and safe for treating HCV-infected RTRs and without significant AE.

Abstract
Chronic hepatitis C virus infection is a global health problem, especially among renal transplant recipients. Herein, we present an overview of hepatitis C virus among renal transplant patients, with a focus on some updated aspects concerning types of viral genotypes, methods of diagnosis, the effects of renal transplant on hepatitis C virus infection, and summary of hepatitis C virus-related complications after renal transplant. We also discuss patient and graft survival rates and the present and future therapeutic options with special focus on new antiviral and possible interactions with immunosuppressive medications.

Abstract
There is no approved therapy for hepatitis C virus (HCV) infection after kidney transplantation, and no data regarding the use of new-generation direct antiviral agents (DAAs) have been published so far. The aims of this pilot study were to assess the efficacy and safety of an interferon-free sofosbuvir-based regimen to treat chronic HCV infection in kidney transplant recipients. Twenty-five kidney transplant recipients with chronic HCV infection were given, for 12 (n = 19) or 24 weeks (n = 6), sofosbuvir plus ribavirin (n = 3); sofosbuvir plus daclatasvir (n = 4); sofosbuvir plus simeprevir, with (n = 1) or without ribavirin (n = 6); sofosbuvir plus ledipasvir, with (n = 1) or without ribavirin (n = 9); and sofosbuvir plus pegylated-interferon plus ribavirin (n = 1). A rapid virological response, defined by undetectable viremia at week 4 after starting DAA therapy, was observed in 22 of the 25 patients (88%). At the end of therapy, HCV RNA was undetectable in all patients. At 4 and 12 weeks after completing DAA therapy, all had a sustained virological response. The tolerance to anti-HCV therapy was excellent and no adverse event was observed. A significant decrease in calcineurin inhibitor levels was observed after HCV clearance. New-generation oral DAAs are efficient and safe to treat HCV infection after kidney transplantation.

Abstract
Background. There are few data on the combination of (pegylated-) interferon- (Peg-IFN-) α, ribavirin, and first-generation direct-acting antiviral agents (DAAs). Our aim was to describe the efficacy and safety of Peg-IFN-α, ribavirin, and boceprevir in hemodialysis patients. Patients. Six hemodialysis patients, chronically infected by genotype-1 HCV, were given Peg-IFN-α (135 µg/week), ribavirin (200 mg/d), and boceprevir (2400 mg/d) for 48 weeks. Results. At initiation of antiviral therapy, median viral concentration was 5.68 (3.78–6.55) log IU/mL. HCV RNA was undetectable in four of the six patients at week 4 and in all patients at week 24. A breakthrough was observed in two patients between weeks 24 and 48, and a third patient stopped antiviral therapy between weeks 24 and 48 because of severe peripheral neuropathy. At week 48, HCV RNA was undetectable in three patients. Of these, two patients relapsed within a month after antiviral therapy was stopped. Hence, only one patient had a sustained virological response; he was a previous partial responder. Overall, anemia was the main side effect. Conclusion. A triple antiviral therapy based on Peg-IFN-α, ribavirin, and boceprevir is not optimal at treating hemodialysis patients with chronic HCV infection. Studies using new-generation drugs are required in this setting.

Abstract
Fibrosing cholestatic hepatitis (FCH) is an uncommon complication of renal transplantation and usually associated with hepatitis B and C viral infection. Without treatment, the prognosis is usually fatal within weeks of onset. There was rarely report with successful treatment intervention. This case report describes a uremic patient with HCV infection who developed a fatal form of FCH after kidney transplantation. This is the first reported successful case with allogeneic hematopoietic stem cell transplantation (AHSCT) without ablative conditioning. A dramatic virologic and clinical improvement was observed in this post-transplantation patient. But no adverse events related to AHSCT were observed. The patient returned to work full-time at 10 months of hospitalization and is still in good health by now. Serum HCV RNA gradually decreased from 2.5 × 10 (6) Copies/mL at day 1 to 3.2 × 10 (4) Copies/mL at day 98 and became negative (<400 Copies/mL) at day 126 of hospitalization and remains negative at the last available assessment. Our report suggests that allogeneic HSCT may have a therapeutic role in FCH.

Abstract
AbstractHepatitis C virus is presently a major public health problem across the globe. The main objective in treating hepatitis C virus (HCV) infection is to achieve a sustained virological response (SVR). Interferon-α (IFN-α) and pegylated interferon (PegIFN) in combination with Ribavirin (RBV) are the choice of treatment nowadays against chronic hepatitis C. There are several mechanisms evolved by the hepatitis C virus that facilitate the persistence of virus and further lead the patient’s status as non responder. Various factors involved in patient’s lack ofresponse to the therapy include: (1) viral factors, (2) host factors, (3) molecular mechanisms related to the lack of response and (4) social factors. Herein we have made an attempt to summarize all the related predictors of drug resistance in one article so that the future polices can be planned to overcome this obstacle and potential therapies can be designed by considering these factors.

Abstract
Recurrence of glomerulonephritis following renal transplantation is considered an important cause of allograft failure. The incidence of recurrence of glomerulonephritis varies widely depending on the definition of recurrence (pathologic recurrence or clinicopathologic recurrence) and the original glomerular disease. Moreover the impact of recurrence of glomerular disease on allograft outcome varies widely between different forms of glomerulonephritis. Whereas IgA nephritis recurs in up to one third of transplanted patients, this is not associated with adverse effects on graft survival. In contrast, recurrent focal segmental glomerulosclerosis and membranoproliferative glomerulopathy have an unfavorable prognosis. Overall, long-term graft survival in patients transplanted for glomerulonephritis is comparable to survival in patients with other causes of ESRD. In recent years, several mechanisms for recurrent disease after transplantation (e.g. PLA2R antibodies in membranous nephropathy and suPAR in FSGS) have been identified, and these findings have helped to elucidate the pathogenesis of glomerular diseases. Although renal transplantation is the treatment of choice for end-stage renal disease as a consequence of glomerulonephritis, further studies are required to develop optimal strategies to prevent, diagnose and treat recurrent glomerular diseases.

Abstract
BACKGROUND Fibrosing cholestatic hepatitis C (FCH-C) is a rare entity that occurs among immune-compromised patients resulting from the direct hepatotoxicity of a high intracellular viral load along with an ineffective immune system ultimately leading to a fatal outcome. We have describes herein 4 renal transplant recipients who were diagnosed with FCH-C at our institution in the last 8 months. METHODS Four renal transplant recipients presented with jaundice and deteriorating liver function tests. They were diagnosed to display FCH-C based on the presence of hepatitis C virus (HCV) RNA and characteristic liver biopsy findings; there was no evidence of any other cause of cholestasis or biliary obstruction. RESULTS The patients were men of ages 40, 25, 20, and 27 years. The durations after transplantation were 1.5, 10, 1.5 and 2.0 years, respectively. In all cases pretransplantation screening was negative for HCV antibody, HCV RNA, and hepatitis B surface antigen (HBsAg). All 4 patients were infected with genotype 1, whereas case 2 had coinfection with type 3. Cases 1 and 2 who were treated with interferon and ribavirin, showed improvement in cholestasis but did not achieve a rapid virological response. Case 1 developed graft dysfunction secondary to acute cellular rejection at 4 months after initiation of interferon treatment, which was treated with pulse steroids. Interferon-based therapy was stopped prematurely in both cases due to pancytopenia. Case 3 developed florid pyelonephritis and died without receiving therapy for hepatitis C. Case 4 was managed conservatively by decreasing the immunosuppression with regular monitoring. CONCLUSION FCH-C is difficult to treat and shows high morbidity and mortality rates. Treatment is associated with a risk of graft rejection.

Abstract
Viruses are among the most common causes of opportunistic infection after transplantation. The risk for viral infection is a function of the specific virus encountered, the intensity of immune suppression used to prevent graft rejection, and other host factors governing susceptibility. Although cytomegalovirus is the most common opportunistic pathogen seen in transplant recipients, numerous other viruses have also affected outcomes. In some cases, preventive measures such as pretransplant screening, prophylactic antiviral therapy, or posttransplant viral monitoring may limit the impact of these infections. Recent advances in laboratory monitoring and antiviral therapy have improved outcomes. Studies of viral latency, reactivation, and the cellular effects of viral infection will provide clues for future strategies in prevention and treatment of viral infections. This paper will summarize the major viral infections seen following transplant and discuss strategies for prevention and management of these potential pathogens.

Abstract
Hepatitis C virus, which usually starts during dialysis therapy, is currently the main cause of chronic liver disease in such population. The majority of patients acquired the disease through intravenous drug use or blood transfusion, with some risk factors identified. In this review we are dealing with the effect of renal transplantation on HCV infection and HCV-related complications after renal transplantation. Moreover, we are discussing the therapeutic options of HCV infection before and after renal transplantation, the best immunosuppressive protocol and lastly graft and patient survival in patients who underwent pretransplant management vs. those who were transplanted without treatment.

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
Liver transplantation is currently the only definitive modality for the treatment of end-stage liver disease due to chronic hepatitis C. However, recurrent hepatitis C after liver transplantation is nearly universal. Cirrhosis may develop in 20% of recipients within 5 years, and recurrent hepatitis C may lead to graft failure, retransplantation, and even death. A subset of recipients may develop post-liver transplant cholestatic hepatitis C (PLTCHC), which is characterized by cholestasis, hepatocyte ballooning, and rapid progression to graft failure. We present a systematic review of PLTCHC that is focused on hepatitis C-infected liver transplant recipients. We compare the pathological definitions of PLTCHC, clinical factors, management strategies, and outcomes reported in studies. We found differences among studies in the types of histological criteria used to diagnose PLTCHC during liver biopsy and in the types of clinical information provided. Three of the 12 studies published after 2003 used the definition of PLTCHC published by the first International Liver Transplantation Society expert panel consensus conference on liver transplantation and hepatitis C. We propose that studies on PLTCHC use the consensus criteria for diagnosis and suggest clinical information that should be provided in future studies with the goal of improving our understanding and management of this deadly disease.

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
Chronic kidney disease (CKD) has become a major public health problem worldwide over the past few decades because of the increasing prevalence of hypertension, diabetes mellitus, and elderly individuals in most countries. Chronic viral hepatitis (due to hepatitis B virus (HBV) and hepatitis C virus (HCV)) also poses significant morbidity and mortality globally. Both these viruses can cause CKD and these infections can occur as a consequence of CKD management. CKD patients acquiring HBV or HCV infection have higher morbidity and mortality rates, and the management of these infections among CKD patients with antiviral agents is associated with high rates of adverse effects. The optimal management of CKD associated with HBV and HCV is not well defined because of insufficient data from clinical trials. This review discusses the pathogenesis, clinical characteristics and management issues related to chronic viral hepatitis and CKD.

Abstract
Recurrence of the primary disease has become a major focus for transplant hepatologists both when investigating graft dysfunction and when tailoring immunosuppression to maximize graft survival. However, disease recurrence varies in penetrance, can be predictable or random, and does not always conform to the expected pattern of disease. The cholestatic hepatitis syndromes associated with hepatitis B and C are the most dramatic examples of phenotypic change. Being on immunosuppressive drugs may intensify the progression of infectious and malignant diseases, but this effect is not predictable. A significant minority of patients with each of the autoimmune diseases, counter-intuitively, get recurrent disease despite immunosuppression of a potency that is adequate to prevent rejection of the liver graft. Disease patterns emerge after liver transplantation for cryptogenic cirrhosis that shed light on the cause of the native liver disease, for example, nonalcohol-related fatty liver disease and autoimmune hepatitis. The phenotypic expression of disease recurrence can be modified by specific drugs used for immunosuppression and by HLA-antigen matching profiles. Understanding and modifying the phenotypic expression of recurrent disease after liver transplantation is a fertile area for research and continued refinement of clinical care.

Abstract
The consensus meeting for the diagnosis, management and treatment for hepatitis C was held in 45(th) annual meeting for the Japan Society of Hepatology (JSH) in June 2009 where the recommendations and informative statements were discussed including organizers and presenters. The Several important informative statements and recommendations have been shown. This was the fourth JSH consensus meeting of hepatitis C, however, the recommendations have not been published in English previously. Thus, this is the first report of JSH consensus of hepatitis C. The rate of development of hepatocellular carcinoma (HCC) in HCV-infected patients in Japan is higher than in the USA, because the average age of the HCV-infected patients is greater and there are more patients with severe fibrosis of the liver than in the USA. In Japan, more than 60% of HCV-infected patients are genotype 1b infection, and they show lower response to perinterferon and ribavirin combination treatment. To improve the response rate is also an important issue in our country. To establish the original recommendations and informative statements to prevent the development of HCC is a very important issue in Japan.

Abstract
Persistence of hepatitis C virus (HCV) in patients who cleared HCV is still debated. Occult HCV infection is described as the presence of detectable HCV RNA in liver or peripheral blood mononuclear cells (PBMCs) of patients with undetectable plasma HCV-RNA by conventional PCR assays. We have assessed the persistence of HCV in 26 kidney-transplant patients, followed up for 10.5 years (range 2-16), after HCV elimination while on hemodialysis. If HCV really did persist, arising out of the loss of immune control caused by institution of the regimen of immunosuppressive drugs after kidney transplantation, HCV reactivation would have taken place. Their immunosuppression relied on calcineurin inhibitors (100%), and/or steroids (62%), and/or antimetabolites (94%). An induction therapy, given to 22 patients, relied on rabbit antithymocyte globulin (59%) or anti-IL2-receptor blockers (32%). All patients had undetectable HCV RNA as ascertained by several conventional tests. At the last follow-up, no residual HCV RNA was detected in the five liver biopsies, the 26 plasma, and in the 37 nonstimulated and 24 stimulated PBMCs tested with an ultrasensitive RT-PCR assay (detection limit, 2 IU/ml). No biochemical or virologic relapse was seen during follow-up. The absence of HCV relapse in formerly HCV-infected immunocompromised patients suggests the complete eradication of HCV after its elimination while on dialysis.

Abstract
BACKGROUND/AIMS The number of simultaneous liver-kidney transplants (SLK) has increased since the MELD era. Data on short- and long-term outcomes of hepatitis C virus positive (HCV+) SLK compared to HCV+ liver transplant alone (LTA) recipients are limited. METHODS A case-control study comparing outcomes of HCV+SLK versus transplant year-matched HCV+ LTA (1:1) was performed. RESULTS 38/142 (26.7%) SLK recipients were HCV+. LTA controls had lower MELD (17.4+/-8.6) at transplant than SLK (34.5+/-6.6) (p=0.001). There were increased early post-transplant infection episodes in SLK (56.3%) versus LTA (21.6%) (p=0.001) and a trend towards increased early mortality in the SLK group (p=0.08). However, there was no difference in long-term patient and graft survival, time to HCV recurrence, % >or=stage 2 fibrosis, renal function, and graft function between the groups. Ten SLK recipients were treated for HCV recurrence with pegylated interferon+ribavirin: two had sustained virologic response, five stopped due to side effects, and three had no response. None had liver or kidney rejection on treatment. CONCLUSION Our data represent the largest analysis of HCV+ SLK outcomes to date. We demonstrate increased early complications in SLK versus LTA recipients, likely due to being more critically ill at transplant (higher MELD) and complications unrelated to HCV within the first year. However, long-term outcomes, i.e. HCV recurrence, graft/renal dysfunction, are similar to LTA. In addition, while data are limited, treatment of HCV recurrence with interferon appeared safe in our SLK recipients.

Abstract
The aim of this study was to compare the clinical characteristics of recurrent and de novo membranous glomerulopathy (MG) among a cohort of 614 recipients transplanted between 1989 and 2006. Lupus nephritides were excluded. The diagnosis was established on protocol biopsies performed 1, 2, 4, or 8 years after transplantation or because of proteinuria/nephrotic syndrome and/or an increased serum creatinine level. HCV infection, cryoglobulinemia, monoclonal gammopathy, skin cancers, Kaposi sarcoma, diabetes mellitus, anti-HLA antibodies, and graft survival were not significantly different between the groups. Seventeen MG were diagnosed in 15 patients (2.45% of the whole group), including 6 recurrent MG (35%) and 11 de novo MG (75%). Recurrent MG occurred earlier than de novo MG (15.58 +/- 19.13 vs 49.27 +/- 32.71 months). Recipients with de novo MG were more frequently infected with HCV, which seemed to be the main etiologic factor for de novo MG, and may be linked to a Th2 polarization of the immune response.

Abstract
Hepatitis C virus (HCV) infection is the most frequent cause of liver disease after renal transplantation. Its clinical course is irrelevant in the short term, except for rare cases of fibrosing cholestatic hepatitis. However, in the long run, HCV infection can lead to major liver complications. Because interferon (IFN) is generally contraindicated in renal transplant patients, the best approach is to treat patients on dialysis. Until more information with pegylated-IFN is available, the use of alpha-IFN monotherapy is recommended. Most of the patients with sustained virological response remain HCV RNA negative after transplantation. HCV-positive renal transplant patients have a higher risk for proteinuria, chronic rejection, infections and post-transplant diabetes (PTDM). Long-term patient- and graft-survival rates are lower in HCV-positive patients. Mortality is higher, mainly as a result of liver disease and infections. HCV can contribute to the development of certain neoplasias such as post-transplant lymphoproliferative disease (PTLD). HCV infection is also an independent risk factor for graft loss. PTDM, transplant glomerulopathy and HCV-related glomerulonephritis can contribute to graft failure. Despite this, transplantation is the best option for end-stage renal disease in HCV-positive patients. Several measures to minimize the consequences of HCV infection have been recommended. Adjustment of immunosuppression and careful follow up in the outpatient clinic for early detection of HCV-related complications are mandatory.

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
Hepatitis C is one of the most common indications for liver transplantation in the United States, accounting for approximately 40%-45% of all liver transplants. Unfortunately, recurrent disease is universal in patients who are viremic before transplantation. This can lead to cirrhosis in at least 25% of patients 5 years after liver transplantation, and recurrent hepatitis C is now emerging as an important but occasionally contentious indication for retransplantation. Several attempts have been undertaken to identify patients at high risk for severe recurrent disease who may benefit from treatment, but unfortunately antiviral therapy frequently is ineffective and often is associated with numerous side effects. Although we have made significant strides in understanding the natural history of this disease in nontransplant patients, this does not hold true for the transplant population in which several uncertainties covering virtually the entire spectrum of liver transplantation persist. Despite these concerns, on a more practical level, it is usually only in the postoperative setting that clinicians truly can assess the impact of their interventions on the natural history of recurrent hepatitis C, for example, by adjusting immunosuppression or prescribing antiviral therapy. Preoperative and perioperative (including donor) factors often are outside the control of hepatologists and transplant surgeons. This review is not an inclusive review of the literature but summarizes what we believe are the more controversial topics of this disease.

Abstract
The complex care that must be provided for patients with renal disease might interfere with provision of basic preventive measures in this population. Preventive health care, including infection screening and prophylaxis, vaccinations, management of blood glucose and lipid levels, and cancer screening, is important, as it might decrease acute morbidity and mortality. This Review highlights useful preventive and health maintenance strategies for patients with chronic kidney disease and those with end-stage renal disease.

Abstract
Hepatitis C virus (HCV) infection is a significant cause of morbidity and mortality in hemodialysis (HD) patients. The reported prevalence of HCV among the HD population has varied greatly from 1.9 to 84.6% in different countries in recent years. The length of time on HD is generally believed to be associated with HCV acquisition in HD subjects. Nevertheless, several recent reports failed to recognize any significant role of blood transfusion. Although there are some considerations about the accuracy of serologic testing in detecting HCV in HD patients, the accumulated data in this review suggest the false-negativity rate to be not more than 1.66% (153/9,220). Therefore, substituting virologic for serologic testing in the routine diagnosis of HCV infection in HD patients seems unreasonable. Several phylogenetic analyzes of viral isolates suggested nosocomial patient-to-patient transmission of HCV among HD patients for which the main potential source is believed to be contaminated hands and articles. However, isolation of HCV-infected HD patients and use of dedicated machines are currently unjustified while strict adherence to universal precautions seems to be enough to control disease spread in HD units. The present article is an update on epidemiological and clinical features of HCV in HD population.

Abstract
Patients with chronic hepatitis C virus (HCV) infection and disease-related complications - among them cirrhosis and liver failure - pose a particular management challenge. Some of these patients may fail to respond to current therapy (non-responders), and some are affected so severely that treatment puts them at an unacceptable risk for complications. Treatment with pegylated interferon (peg-IFN) plus ribavirin improves hepatic enzyme levels and eradicates the virus in approximately 50% of patients; however, a significant number of patients do not respond to therapy or relapse following treatment discontinuation. Several viral, hepatic and patient-related factors influence response to IFN therapy; many of these factors cannot be modified to improve long-term outcomes. Identifying risk factors and measuring viral load early in the treatment can help to predict response to IFN therapy and determine the need to modify or discontinue treatment. Retreatment options for patients who have failed therapy are limited. Retreatment with peg-IFN has been successful in some patients who exhibit an inadequate response to conventional IFN treatment, particularly those who have relapsed. Consensus IFN, another option in treatment-resistant patients, has demonstrated efficacy in the retreatment of non-responders and relapsers. Although the optimal duration of retreatment and the benefits and safety of maintenance therapy have not been determined, an extended duration is likely needed. This article reviews the risk factors for HCV treatment resistance and discusses the assessment and management of difficult-to-treat patients.
