Abstract
The hepatitis C virus mainly infects the liver but is also able to infect and replicate in other body compartments by creating an extra-hepatic reservoir that may influence the persistence of the infection after transplantation. It is unknown whether antiviral drugs affect the viral extra-hepatic sites. We evaluated the ability of pegylated/interferon + ribavirin and sofosbuvir + ribavirin to clear the virus from the gastrointestinal mucosa of liver-transplanted patients with HCV recurrence after transplantation. A total of 51 liver-transplanted patients, 30 treated with pegylated/interferon + ribavirin (ERA1) and 21 treated with sofosbuvir + ribavirin (ERA2), were enrolled, and blood serum and gastrointestinal tissues analyzed for the presence of HCV-RNA. In the ERA1 group, the 46.6% of patients had a sustained viral response to antiviral treatment, and gastrointestinal biopsies were positive for HCV in 73.3% of cases, 54.5% of responders, and 45.5% of non-responders. In the ERA2 group, the 66.6% had a sustained viral response, and gastrointestinal HCV-RNA was present in the 14.3% of patients, all relapsers. Sofosbuvir + ribavirin cleared the intestinal HCV in 85.7% of patients with recurrent HCV infection, while pegylated/interferon + ribavirin cleared it in 26.6% of treated patients, demonstrating the better effectiveness of new direct antiviral agents in clearing HCV intestinal reservoir.

Abstract
Objectives Direct antiviral agents (DAA) has dramatically improved the therapy outcome of hepatitis C-virus (HCV) infection, both on the waiting-list and post liver transplantation (LT). DAA are generally well-tolerated in patients with mild to moderate liver and kidney failure, but some DAAs are contraindicated in patients with severe dysfunction of these organs. Today there are few studies of peri-LT DAA use and treatment is commonly discontinued at the time of LT. We report here our experience of DAA therapy given continuously in the perioperative LT period in a real-life setting in Sweden. Material In total 10 patients with HCV-cirrhosis, with or without hepatocellular carcinoma, and a median age of 60.5 years (range, 52–65) were treated with DAAs on the waiting list for LT, and continued in the early postoperative period without any interruption, on the basis of not having reached a full treatment course at the time of LT. Sofosbuvir and a NS5A inhibitor with or without ribavirin, or sofosbuvir and ribavirin only, were given. The distribution of genotypes was genotype 1 and 3, in 4 and 6 patients, respectively. Six of the 10 patients had previously been treated with IFN-based therapy. Results There were no adverse events leading to premature DAA discontinuation. All recipients achieved a sustained viral response 12 weeks after end-of-treatment (SVR12). At the time of LT the median MELD-score was 16.5 (range 7–21), CTP-score 9.0 (range 5–10), creatinine 82.5 μmol/L (range 56–135, reference 60–105), bilirubin 33 μmol/L (range 16–79, reference 5–25) and PK-INR 1.5 (range 1.1–1.8). The median duration of DAA therapy was 60 days (range 18–132) pre-LT, 54 days post-LT (range 8–111 days) and in total 15.5 weeks (range 12–30 weeks). Conclusion Interferon-free DAA therapy of HCV-infection given in the immediate pre- and post-operative LT period is safe, well-tolerated and yields high SVR rates.

Abstract
PURPOSE To report the effect of partial splenic embolization (PSE) on hematological indices and the procedure's safety in pre- and post-liver transplant (LT) patients. MATERIALS AND METHODS A single-center retrospective study evaluating all patients who underwent PSE over a 16-year period was performed. Inclusion criteria were splenomegaly confirmed by imaging and at least one of the following cytopenias: hemoglobin ≤10 g/dL, WBC count ≤1500 μL-1, or platelet count ≤100,000 μL-1. 38 of 102 patients (37%) met criteria (24 pre- and 14 post-LT) for a total of 40 PSEs. RESULTS No effect was seen on median hemoglobin beyond 2 weeks post-PSE. There was a significant and sustained increase in median WBC counts (from 3400 μL-1 to 5400 μL-1 at 2 years) and platelet count (from 65,000 μL-1 to 117,000 μL-1 at 3.5 years). In 6 out of 40 PSEs (15%) a major complication occurred which included pleural effusion, ascites, spontaneous bacterial peritonitis, pneumonia, and inferior vena cava thrombus. Similar efficacy was observed in pre- and post-LT cohorts, with a trend toward higher complication rate in pre-LT patients. CONCLUSIONS PSE is efficacious in increasing WBC count out to 2 years and platelet count out to 3.5 years in patients with hypersplenism. Efficacy and safety appeared independent of pre- or post-LT status. The intervention is associated with major complications and special care should be taken when selecting patients for PSE.

Abstract
Interferon treatment of hepatitis C virus (HCV) infection after liver transplantation (LT) can result in immune-mediated graft dysfunction (IGD). The occurrence of, risk factors for, and outcomes of IGD with direct-acting antiviral (DAA) therapy have not been reported. We conducted a multicenter study of HCV+LT recipients who did or did not develop DAA-IGD (1 case: 2 controls-33 vs 66). Among all treated between 2014 and 2016, DAA-IGD occurred in 3.4% (33/978). IGD occurred only after treatment completion (76.0 [IQR, 47.0;176]). Among those treated, 48% had plasma cell hepatitis, 36% acute cellular rejection, 6% chronic rejection, and 9% combined findings. Median time to liver enzyme resolution was 77.5 days (IQR, 31.5;126). After diagnosis, hospitalizations, steroid-induced hyperglycemia, and infection occurred in a higher percentage of cases vs controls (33% vs 7.5%, 21% vs 1.5%, 9% vs 0%; all P < .05). Only one IGD patient died and none required retransplant. A multivariate regression analysis found that liver enzyme elevations during and soon after DAA therapy completion correlated with subsequent IGD. In conclusion, while DAA-IGD is uncommon, liver enzyme elevations during or after DAA therapy may be a sign of impending IGD. These indicators should guide clinicians to diagnose and treat IGD early before the more deleterious later clinical presentation.

Abstract
BACKGROUND The number of patients needing liver transplantation (LT) exceeds the number of available allografts. The current opioid epidemic in this country has increased the number of potential donors infected with hepatitis C (HCV). METHODS We assessed the incremental cost-effectiveness ratio (ICER) by comparing the costs and number of liver transplants performed using HCV-positive and HCV-negative grafts into patients without HCV infection in a decision analysis model with a 1-year time horizon. RESULTS The use of HCV-positive grafts was found to have an ICER below $50 000 across all MELD scores. Using our baseline cohort with a model for end-stage liver disease (MELD) score of 15-22, the ICER was $21 233/additional LT performed. As the MELD scores increased, the ICER decreased. Above a MELD score of 23, the use of HCV-positive grafts became cost saving (-$115 419). Our model was robust to all variables tested in the sensitivity analyses, except drug costs. CONCLUSION The results of our decision analysis model highlight the potential pharmacoeconomic benefit of utilizing HCV-positive grafts in LT candidates who are not infected with HCV. The use of HCV-positive grafts is at least cost effective and even cost saving in patients with MELD scores above 23.

Abstract
AIM To investigate the specific effects of immunosuppressants on the antiviral action of daclatasvir and asunaprevir.
METHODS The antiviral activity of daclatasvir (DCV) and asunaprevir (ASV) combined with immunosuppressants was tested using two in vitro models for hepatitis C virus (HCV) infection.
RESULTS Tacrolimus, rapamycin and cyclosporine did not negatively affect the antiviral action of DCV or ASV. Mycophenolic acid (MPA) showed additive antiviral effects combined with these direct acting antivirals (DAAs). MPA induces interferon-stimulated genes (ISGs) and is a potent GTP synthesis inhibitor. DCV or ASV did not induce ISGs expression nor affected ISG induction by MPA. Rather, the combined antiviral effect of MPA with DCV and ASV was partly mediated via inhibition of GTP synthesis.
CONCLUSION Immunosuppressants do not negatively affect the antiviral activity of DAAs. MPA has additive effect on the antiviral action of DCV and ASV. This combined benefit needs to be confirmed in prospective clinical trials.

Abstract
Long-term functional outcomes of sofosbuvir-based antiviral treatment were evaluated in a cohort study involving 16 Italian centres within the international compassionate use programme for post-transplant hepatitis C virus (HCV) recurrence. Seventy-three patients with cirrhosis (n=52) or fibrosing cholestatic hepatitis (FCH, n=21) received 24-week sofosbuvir with ribavirin±pegylated interferon or interferon-free sofosbuvir-based regimen with daclatasvir/simeprevir+ribavirin. The patients were observed for a median time of 103 (82-112) weeks. Twelve of 73 (16.4%) died (10 non-FCH, 2 FCH) and two underwent re-LT. Sustained virological response was achieved in 46 of 66 (69.7%): 31 of 47 (66%) non-FCH and 15 of 19 (79%) FCH patients. All relapsers were successfully retreated. Comparing the data of baseline with last follow-up, MELD and Child-Turcotte-Pugh scores improved both in non-FCH (15.3±6.5 vs 10.5±3.8, P<.0001 and 8.4±2.1 vs 5.7±1.3, P<.0001, respectively) and FCH (17.3±5.9 vs 10.1±2.8, P=.001 and 8.2±1.6 vs 5.5±1, P=.001, respectively). Short-treatment mortality was higher in patients with baseline MELD≥25 than in those with MELD<25 (42.9% vs 4.8%, P=.011). Long-term mortality was 53.3% among patients with baseline MELD≥20 and 7.5% among those with MELD<20 (P<.0001). Among deceased patients 75% were Child-Turcotte-Pugh class C at baseline, while among survivors 83.9% were class A or B (P<.0001). Direct acting antivirals-based treatments for severe post-transplant hepatitis C recurrence, comprising fibrosing cholestatic hepatitis, significantly improve liver function, even without viral clearance and permit an excellent long-term survival. The setting of severe HCV recurrence may require the identification of "too-sick-to-treat patients" to avoid futile treatments.

Abstract
Hepatitis C virus (HCV) infection represents a worldwide health problem and has been for long an attractive point of research due to diversity among different genotypes regarding unique geographical distribution and diverse treatment outcome. HCV is considered a major cause of chronic liver disease and cirrhosis, which leads to liver failure and hepatocellular carcinoma requiring liver transplantation. Of the HCV genotypes identified, HCV genotype 4 (HCV-4) is the least studied. HCV-4 is responsible for ∼10% of HCV infections and is common in the Middle East and Africa; recently it is increasingly prevalent in European Countries. HCV-4 is a continuing epidemic in Egypt, having the highest prevalence of HCV worldwide. "Know your epidemic, know your response" concept necessitates better understanding of HCV-4 characteristics to control disease dissemination and progression, which compromises the life quality of chronic HCV-infected patients. In this review, we discuss the epidemiology, natural history, and treatment options for patients with HCV-4 infection.

Abstract
BACKGROUND Relapse of hepatitis C virus (HCV) infection after liver transplantation has been universal, and the fibrosis progression faster than in non-transplanted patients. Interferon (IFN)-free treatment with direct antiviral agents (DAA) has improved the treatment outcome dramatically. We here report on the outcome of IFN-free treatment for HCV relapse after liver transplantation in a real life setting in Sweden. MATERIAL In total, 93 patients with a mean age of 60 years (range 32-80) with HCV relapse after liver transplantation were given sofosbuvir-based treatment in combination with a protease inhibitor (simeprevir) or a NS5A inhibitor (daclatasvir or ledipasvir) with or without addition of ribavirin (RBV), or sofosbuvir and RBV only. Treatment was generally given during 24 weeks for advanced fibrosis or cirrhosis cases and 12 weeks for mild fibrosis with fibrosis stage 2 or less. The distribution of genotype 1, 2, 3, 4 in our patients was 58, 7.5, 26.5 and 7.5%, respectively. RESULTS All recipients reached end-of-treatment response (ETR) with HCV RNA <15 IU/mL. Sustained viral response 12 weeks after treatment cessation (SVR12) was achieved in 91/93 (97.8%) recipients. The SVR12 rates for genotype 1, 2, 3 and 4 were the SVR12 rate were 96, 100, 100 and 100%, respectively (p = .04). CONCLUSION It is concluded that IFN-free treatment with DAAs for HCV relapse after liver transplantation is highly effective also in a real life setting and offers cure for most recipients.

Abstract
Hepatitis C virus (HCV) is a hepatotropic RNA virus that causes progressive liver damage, which might result in liver cirrhosis and hepatocellular carcinoma. Globally, between 64 and 103 million people are chronically infected. Major risk factors for this blood-borne virus infection are unsafe injection drug use and unsterile medical procedures (iatrogenic infections) in countries with high HCV prevalence. Diagnostic procedures include serum HCV antibody testing, HCV RNA measurement, viral genotype and subtype determination and, lately, assessment of resistance-associated substitutions. Various direct-acting antiviral agents (DAAs) have become available, which target three proteins involved in crucial steps of the HCV life cycle: the NS3/4A protease, the NS5A protein and the RNA-dependent RNA polymerase NS5B protein. Combination of two or three of these DAAs can cure (defined as a sustained virological response 12 weeks after treatment) HCV infection in >90% of patients, including populations that have been difficult to treat in the past. As long as a prophylactic vaccine is not available, the HCV pandemic has to be controlled by treatment-as-prevention strategies, effective screening programmes and global access to treatment.

Effectiveness and tolerability of simeprevir and sofosbuvir in nontransplant and post-liver transplant patients with hepatitis C genotype 1. Aliment Pharmacol Ther 2016; 44:738-46. [PMID: 27506182 DOI: 10.1111/apt.13761] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2016] [Revised: 06/16/2016] [Accepted: 07/21/2016] [Indexed: 12/23/2022]
Abstract
BACKGROUND Hepatitis C virus genotype 1a (HCV-1a), prior treatment, cirrhosis and post-transplant status are historically associated with poor treatment responses. The new oral direct-acting agents appear to be effective and safe in these patients. AIMS To evaluate the effectiveness and tolerability of simeprevir and sofosbuvir in a diverse real-life cohort of patients, including difficult-to-treat patients. METHODS We conducted a retrospective cohort study in 198 consecutive patients with hepatitis C genotype 1 (148 nontransplant, 50 post transplant), who were treated with simeprevir and sofosbuvir for 12 weeks between December 2013 and December 2014. Primary outcome was sustained virological response with undetectable HCV RNA 12 weeks after completion of therapy (SVR12). Risk factors evaluated for lack of SVR12 included HCV 1a (vs. 1b), prior treatment (vs. none), and cirrhosis (vs. no cirrhosis). RESULTS SVR12 rates were similar in non- and post-transplant settings, 82% and 88%, respectively. There were no significant differences in adverse events in patients regardless of cirrhosis or transplant status. On multivariate analysis also inclusive of gender and liver transplant status, negative predictors of SVR12 were having at least 2 or 3 risk factors (OR 0.30, 95% CI 0.10-0.87, P = 0.027 or 0.29, 95% CI 0.09-0.85, P = 0.025, respectively). CONCLUSION Simeprevir and sofosbuvir combination is a safe and effective regimen for the treatment of non- and post-transplant patients with traditional risk factors for poor treatment response, unless more than 2 difficult-to-treat risk factors are present.

Abstract
Liver transplantation has emerged as an established and well-accepted therapeutic option for patients with acute and chronic liver failure and hepatocellular carcinoma. The disproportion between recipients and donors is still an ongoing problem that has only been solved partially over the last centuries. For several patients no life-saving organs can be distributed. Therefore, objective and internationally established recommendations regarding indication and organ allocation are imperative. The aim of this article is to establish evidence-based recommendations regarding the evaluation and assessment of adult candidates for liver transplantation. This publication is the first Austrian consensus paper issued and approved by the Austrian Society of Gastroenterology and Hepatology in cooperation with the Austrian Society of Transplantation, Infusion and Genetics.

Abstract
PURPOSE OF REVIEW This article reviews treatment options of the approved and soon-to-be approved direct-acting antiviral (DAA)-based therapies in the transplant setting. RECENT FINDINGS DAA-based therapies have been shown to be effective and safe in achieving viral eradication in the majority of pre- and postliver transplant (LT) populations. Treatment decisions are guided by hepatitis C virus (HCV) genotype, the degree of renal dysfunction, and severity of cirrhosis. The addition of ribavirin is frequently needed to achieve highest viral eradication rates. Viral eradication pre-LT has been associated with fewer portal hypertensive complications and improved survival and effectively prevents recurrent HCV post-LT. For those with shorter time to LT, an alternative strategy is treatment with DAAs up to the time of LT to reduce the risk of post-LT recurrence. Therapies should be considered for all post-LT patients with recurrent HCV given the risk of accelerated disease progression. The sustained virological response rates among LT recipients parallel those of nontransplant patients. SUMMARY With broader application of DAA therapy in the transplant setting, improved graft and patient survival and simplified post-LT management are likely. The availability of high potency DAA therapy with excellent safety profiles has transformed the HCV-infected LT population into a group that is no longer 'difficult-to-treat.'

Abstract
Hepatitis C virus (HCV) infection is a major biomedical problem worldwide. Although new direct antiviral agents (DAAs) have been developed for the treatment of chronic HCV infection, the potential emergence of resistant virus variants and the difficulties to implement their administration worldwide make the development of novel antiviral agents an urgent need. Moreover, no effective vaccine is available against HCV and transmission of the virus still occurs particularly when prophylactic measures are not taken. We used a cell-based system to screen a battery of polyanionic carbosilane dendrimers (PCDs) to identify compounds with antiviral activity against HCV and show that they inhibit effective virus adsorption of major HCV genotypes. Interestingly, one of the PCDs irreversibly destabilized infectious virions. This compound displays additive effect in combination with a clinically relevant DAA, sofosbuvir. Our results support further characterization of these molecules as nanotools for the control of hepatitis C virus spread.

Abstract
End-stage liver disease secondary to hepatitis C virus (HCV) infection is the major indication for orthotopic liver transplantation (OLT) worldwide. The percentage of HCV patients infected with genotype 4 (G4) among recipients of OLT varies depending on geographic location. In the Middle East, including Saudi Arabia, G4 infection is the most common genotype among transplant recipients. Due to the low prevalence of HCV-G4 in Europe and the United States, this genotype has not been adequately studied in prospective trials evaluating treatment outcomes and remains the least studied variant. The aim of this review is to summarize the natural history and treatment outcome of HCV-G4 following liver transplantation, with particular attention to new HCV therapies. This review incorporates all published studies and abstracts including HCV-G4 patients.

Abstract
The anti-hepatitis C virus (HCV) activity of a novel monoclonal antibody (mAb; AR4A) and epigallocatechin gallate (EGCG) were studied in vitro using a HCV cell culture system and in vivo using a humanized liver mouse model capable of supporting HCV replication. Alone, both exhibit reliable cross-genotype HCV inhibition in vitro, and combination therapy completely prevented HCV infection. In vitro AR4A mAb (alone and combined with EGCG) robustly protects against the establishment of HCV genotype 1a infection. EGCG alone fails to reliably protect against an HCV challenge. In conclusion, AR4A mAb represents a safe and efficacious broadly neutralizing antibody against HCV applicable to strategies to safely prevent HCV reinfection following liver transplantation, and it lends further support to the concept of HCV vaccine development. The poor bioavailability of EGCG limits HCV antiviral activity in vitro.

Abstract
Recurrent infection with the hepatitis C virus (HCV) after liver transplantation (LT) is associated with decreased graft and patient survival. Achieving sustained virological response (SVR) with antiviral therapy improves survival. Because interferon (IFN)-based therapy has limited efficacy and is poorly tolerated, there has been rapid transition to IFN-free direct-acting antiviral (DAA) regimens. This article describes the experience with DAAs in the treatment of posttransplant genotype (GT) 1 HCV from a consortium of community and academic centers (Hepatitis C Therapeutic Registry and Research Network [HCV-TARGET]). Twenty-one of the 54 centers contributing to the HCV-TARGET consortium participated in this study. Enrollment criteria included positive posttransplant HCV RNA before treatment, HCV GT 1, and documentation of use of a simeprevir (SMV)/sofosbuvir (SOF) containing DAA regimen. Safety and efficacy were assessed. SVR was defined as undetectable HCV RNA 64 days or later after cessation of treatment. A total of 162 patients enrolled in HCV-TARGET started treatment with SMV+SOF with or without ribavirin (RBV) following LT. The study population included 151 patients treated with these regimens for whom outcomes and safety data were available. The majority of the 151 patients were treated with SOF and SMV alone (n = 119; 79%) or with RBV (n = 32; 21%), The duration of therapy was 12 weeks for most patients, although 15 patients received 24 weeks of treatment. Of all patients receiving SOF/SMV with or without RBV, 133/151 (88%) achieved sustained virological response at 12 weeks after therapy and 11 relapsed (7%). One patient had virological breakthrough (n = 1), and 6 patients were lost to posttreatment follow-up. Serious adverse events occurred in 11.9%; 3 patients (all cirrhotic) died due to aspiration pneumonia, suicide, and multiorgan failure. One experienced LT rejection. IFN-free DAA treatment represents a major improvement over prior IFN-based therapy. Broader application of these and other emerging DAA regimens in the treatment of posttransplant hepatitis C is warranted.

Abstract
AIM: To evaluate the predictors of 10-year survival of patients with hepatitis C recurrence.
METHODS: Data from 358 patients transplanted between 1989 and 2010 in two Italian transplant centers and with evidence of hepatitis C recurrence were analyzed. A χ2, Fisher’s exact test and Kruskal Wallis’ test were used for categorical and continuous variables, respectively. Survival analysis was performed at 10 years after transplant using the Kaplan-Meier method, and a log-rank test was used to compare groups. A P level less than 0.05 was considered significant for all tests. Multivariate analysis of the predictive role of different variables on 10-year survival was performed by a stepwise Cox logistic regression.
RESULTS: The ten-year survival of the entire population was 61.2%. Five groups of patients were identified according to the virological response or lack of a response to antiviral treatment and, among those who were not treated, according to the clinical status (mild hepatitis C recurrence, “too sick to be treated” and patients with comorbidities contraindicating the treatment). While the 10-year survival of treated and untreated patients was not different (59.1% vs 64.7%, P = 0.192), patients with a sustained virological response had a higher 10-year survival rate than both the “non-responders” (84.7% vs 39.8%, P < 0.0001) and too sick to be treated (84.7% vs 0%, P < 0.0001). Sustained virological responders had a survival rate comparable to patients untreated with mild recurrence (84.7% vs 89.3%). A sustained virological response and young donor age were independent predictors of 10-year survival.
CONCLUSION: Sustained virological response significantly increased long-term survival. Awaiting the interferon-free regimen global availability, antiviral treatment might be questionable in selected subjects with mild hepatitis C recurrence.

Abstract
BACKGROUND Relapse of hepatitis C virus (HCV) infection after liver transplantation (LT) is universal. Tolerance for treatment with pegylated-interferon (peg-IFN) and ribavirin (RBV) is suboptimal and withdrawals due to adverse events frequent. We sought to improve tolerance for treatment to improve outcome. METHODS We used concentration-guided RBV dosing to achieve an intended 10 μmol/L concentration with darbepoetin support in combination with peg-IFN alfa-2a, 180 μg for genotype 1 and 135 μg for genotype 2/3 to improve tolerance. RESULTS A total of 51/54 patients (94%) completed a full treatment course. In the per-protocol analysis 43% of patients (22/51) achieved sustained virological response (SVR), 82% with HCV genotype 2/3 and 22% with genotype 1, p = 0.0001. Patients with IL28B CC achieved SVR in 73% (8/11) and patients with non-CC in 33% (14/43), p = 0.016. Patients with mild fibrosis (fibrosis stage 1-2) achieved SVR in 56% (15/27), and patients with advanced fibrosis (fibrosis stage 3-4) in only 26% (7/27), p = 0.0267. CONCLUSIONS Concentration-guided RBV dosing with darbepoetin support substantially improves tolerance and offers high adherence to a full peg-IFN and RBV treatment course in patients with post-transplant HCV relapse. With this approach genotype 2 and 3 infections can be treated cost-effectively post-transplant. Genotype 1, IL28B non-CC genotype, and advanced fibrosis predicted a low SVR rate.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is the leading indication for liver transplantation worldwide, and interferon-containing regimens are associated with low response rates owing to treatment-limiting toxic effects in immunosuppressed liver-transplant recipients. We evaluated the interferon-free regimen of the NS5A inhibitor ombitasvir coformulated with the ritonavir-boosted protease inhibitor ABT-450 (ABT-450/r), the nonnucleoside NS5B polymerase inhibitor dasabuvir, and ribavirin in liver-transplant recipients with recurrent HCV genotype 1 infection. METHODS We enrolled 34 liver-transplant recipients with no fibrosis or mild fibrosis, who received ombitasvir-ABT-450/r (at a once-daily dose of 25 mg of ombitasvir, 150 mg of ABT-450, and 100 mg of ritonavir), dasabuvir (250 mg twice daily), and ribavirin for 24 weeks. Selection of the initial ribavirin dose and subsequent dose modifications for anemia were at the investigator's discretion. The primary efficacy end point was a sustained virologic response 12 weeks after the end of treatment. RESULTS Of the 34 study participants, 33 had a sustained virologic response at post-treatment weeks 12 and 24, for a rate of 97% (95% confidence interval, 85 to 100). The most common adverse events were fatigue, headache, and cough. Five patients (15%) required erythropoietin; no patient required blood transfusion. One patient discontinued the study drugs owing to adverse events after week 18 but had a sustained virologic response. Blood levels of calcineurin inhibitors were monitored, and dosages were modified to maintain therapeutic levels; no episode of graft rejection was observed during the study. CONCLUSIONS Treatment with the multitargeted regimen of ombitasvir-ABT-450/r and dasabuvir with ribavirin was associated with a low rate of serious adverse events and a high rate of sustained virologic response among liver-transplant recipients with recurrent HCV genotype 1 infection, a historically difficult-to-treat population.

Abstract
Single nucleotide polymorphisms of interleukin-28B (IL28B) rs8099917 are reported to be associated with virologic clearance in interferon-and ribavirin -based treatment for hepatitis C virus (HCV)-infected patients. We examined virologic response in accordance with IL28B polymorphisms in our living donor liver transplantation series under a preemptive interferon and RBV treatment approach. Adequate DNA samples from both the recipient and donor for the study of single nucleotide polymorphisms of IL28B were available from 96 cases and were the subjects of the present study. Various clinical factors related with virologic response including early virologic response (EVR) and sustained virologic response (SVR) were examined. Totally 51% presented with EVR and 44% achieved SVR. Presence of the major allele (TT) in either the recipient or the donor corresponded to SVR of 53% and 48%. Presence of the minor allele (TG or GG) corresponded to SVR of 26% and 32%. Multivariate analysis revealed that genotype of HCV or EVR, but not IL28B polymorphisms in either the recipient or donor, was an independent factor for achieving SVR. When virologic response to treatment was incorporated into analysis, the impact of IL28B polymorphism on virological clearance remained relative to other factors and was not significantly independent.

Abstract
BACKGROUND Hepatitis C virus (HCV) is a major cause of liver disease. Infection with HCV is a global public health problem. The virus is classified into 6 genotypes and more than 80 subtypes named as a, b, c, etc. HCV genotyping has been an important parameter for the treatment of HCV infection. OBJECTIVES The main aim of this study was to estimate the prevalence of HCV genotypes in Yazd, central province of Iran. In addition, the study investigated whether there was any association between HCV load and genotypes. PATIENTS AND METHODS This descriptive cross-sectional study was performed on samples suspicious of HCV infection from March 2010 to June 2013. Peripheral blood sample was obtained and screened for anti-HCV antibodies using Enzyme-Linked Immunosorbent Assay (ELISA). Then sera of anti-HCV positive samples were analyzed using quantitative polymerase chain reaction method. Plasma samples were used to determine the HCV genotypes of 1a, 1b, 2, 3, and 4 in 191 infected patients. RESULTS One hundred fifty-two out of 191 (79.6%) samples were from male patients. The mean of the patients' age was 40.7 ± 11.9 years (range 21-75 years old). Sixty- three (33%) patients were included in 31-40 years group. The mean number of HCV in infected patients was 2.92 × 10(6) ± 1.85 × 10(6) copies/mL (Min: 508; Max: 2.75 × 10(8) copies/mL). HCV genotype 3 was the predominant genotype (50.3%) followed by subtypes 1a (38.7%) and 1b (6.8%). The distribution of other HCV genotypes showed genotype 2 in 1.6% and mixed genotypes in 2.6% of positive samples. Genotype 3 was predominant in all age groups except 21-30 years of age group. We were unable to find any significant difference between mean viral load of the patients infected with genotype 3 and those infected with genotype 1 (1a and 1b). CONCLUSIONS Findings of the present study showed that HCV genotype 3 was the predominant genotype followed by the subtypes 1a and 1b in Yazd, central province of Iran. In addition, there was no difference between HCV load and genotypes 1 and 3. HCV genotyping is recommended in other provinces of Iran.

Abstract
Hepatitis C virus—a major global cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma—affects millions of people worldwide. Pegylated interferon (Peg-IFN) and ribavirin (RBV) had been the standard treatment for a decade until availability of the protease inhibitors in 2011. However, current antiviral therapy is still IFN-based and is associated with significant side effects and variable treatment response. Thus, various host and viral factors have been evaluated before and during treatment for the prediction of sustained virologic response to antiviral therapy. In 2009, genome-wide association studies found the single-nucleotide polymorphisms, located near the host interleukin-28B (IL28B) gene that encodes IFN-λ3, to be the best pretreatment predictor of virologic response to Peg-IFN and RBV therapy in chronic hepatitis C genotype 1 patients. Additionally, inosine triphosphatase (ITPA) gene variants were found to be associated with RBV-induced hemolytic anemia, which could affect treatment dose for selected patients. IL28B, ITPA, and other treatment predictors allowed for a potential individualized approach to treat hepatitis C. In the era of increased overall virologic response rates and good tolerability of the rapidly developing non-IFN oral direct-acting antiviral therapy regimens, the need for individualized treatment is likely to diminish. Various predictors of response, including IL28B will likely be of reduced importance in the near future.

Abstract
The IL-28 gene is associated with sustained viral response (SVR) after treatment with peg-IFN and ribavirin in liver transplant recipients with chronic hepatitis C genotype 1 infection. We analysed the importance of recipient and donor IL-28B genotype for response to treatment and fibrosis progression in 54 liver transplant recipients. Fibrosis stage (F) was defined as mild when F≤2 and severe when F≥3 in a liver biopsy or according to liver elasticity analysis. We found a significantly lower prevalence of IL-28B SNP CC in the recipients (22%) than in the donors (67%), P<0.0001. SVR was seen in 61% of the recipients with mild and 27% with severe fibrosis pretreatment, P=0.01. Recipients with IL-28 CC and non-CC had mild fibrosis in 64% and 38% prior to treatment, P=0.13. At follow-up, after treatment, significantly more recipients with CC had mild fibrosis than non-CC recipients (75% versus 32%, P=0.0072), and all with CC and SVR had mild fibrosis. The strongest baseline factor predicting SVR was genotype. Hence, 13/19 (68%) genotype non-1 patients reached SVR versus only 9/35 (26%) genotype 1 patients, P=0.0022. In summary, we found that liver transplant recipients with IL-28B CC tended to have less advanced fibrosis prior to and significantly less after SOC treatment and that all recipients with IL-28B CC who achieved SVR had mild fibrosis at follow-up. A significantly higher SVR rate was achieved in recipients with mild than severe fibrosis pretreatment and with genotype non-1 than 1 infection. Our findings indicate that treatment for post-transplant HCV recurrence should be offered before advanced fibrosis is seen in the recipient.

Abstract
Hepatitis C virus (HCV) is a major health problem that leads to chronic hepatitis, cirrhosis and hepatocellular carcinoma, being the most frequent indication for liver transplantation in several countries. Unfortunately, HCV re-infects the liver graft almost invariably following reperfusion, with an accelerated history of recurrence, leading to 10%-30% of patients progressing to cirrhosis within 5 years of transplantation. In this sense, some groups have even advocated for not re-transplanting this patients, as lower patient and graft outcomes have been reported. However, the management of HCV recurrence is being optimized and several strategies to reduce post-transplant recurrence could improve outcomes, decrease the rate of re-transplantation and optimize the use of available grafts. Three moments may be the focus of potential actions in order to decrease the impact of viral recurrence: the pre-transplant moment, the transplant environment and the post-transplant management. In the pre-transplant setting, it is not well established if reducing the pre transplant viral load affects the risk for HCV progression after transplant. Obviously, antiviral treatment can render the patient HCV RNA negative post transplant but the long-term benefit has not yet been fully established to justify the cost and clinical risk. In the transplant moment, factors as donor age, cold ischemia time, graft steatosis and ischemia/reperfusion injury may lead to a higher and more aggressive viral recurrence. After the transplant, discussion about immunosuppression and the moment to start the treatment (prophylactic, pre-emptive or once-confirmed) together with new antiviral drugs are of interest. This review aims to help clinicians have a global overview of post-transplant HCV recurrence and strategies to reduce its impact on our patients.

Abstract
HCV-related disease is the most common indication for liver transplantation (LT). HCV recurrence, which is almost universal, has a significant impact on patient and graft survival after LT and still represents a great unsolved issue for the liver transplant community. Several treatment strategies have been proposed. Since antiviral therapy has limited efficacy and can be administrated only in selected transplant recipients and additionally that immunosuppressive drugs have a negative impact on HCV re-infection, the achievement of an immunosuppression-free state after LT could play a central role in the avoidance of rapid HCV recurrence.

Abstract
Recurrent HCV disease is the most common cause of graft loss and patient mortality in HCV-infected liver transplant (LT) recipients. Risk factors for more severe recurrence that are potentially modifiable are older donor age, prolonged cold ischaemia time, prior treated acute rejection, CMV hepatitis, IL28B donor genotype, and post-LT insulin resistance. The most effective means of preventing HCV recurrence is eradicating HCV prior to LT. Select wait-list candidates with compensated or mildly decompensated disease can be considered for antiviral treatment with peginterferon, ribavirin (and protease inhibitor if genotype 1). For the majority of LT patients, HCV treatment must be delayed until post-transplant. Treatment is generally undertaken if histologic severity reaches grade 3 or 4 necroinflammation or stage ≥2 fibrosis, or if cholestatic hepatitis. Achievement of sustained viral response (SVR) post-LT is associated with stabilization of fibrosis and improved graft survival. SVR is attained in ~30% of patients treated with peginterferon and ribavirin. Poor tolerability of therapy is a limitation. Combination therapy with telaprevir or boceprevir added to peginterferon and ribavirin is anticipated to increase efficacy but with higher rates of adverse effects and challenges in managing drug-drug interactions between the protease inhibitors and calcineurin inhibitors/sirolimus.

Abstract
Background & Aims Telaprevir, a hepatitis C virus NS3/4A protease inhibitor has significantly improved sustained viral response rates when given in combination with pegylated interferon alfa-2a and ribavirin, compared with current standard of care in hepatitis C virus genotype 1 infected patients. In patients with a failed sustained response, the emergence of drug-resistant variants during treatment has been reported. It is unclear to what extent these variants persist in untreated patients. The aim of this study was to assess using ultra-deep pyrosequencing, whether after 4 years follow-up, the frequency of resistant variants is increased compared to pre-treatment frequencies following 14 days of telaprevir treatment. Methods Fifteen patients from 2 previous telaprevir phase 1 clinical studies (VX04-950-101 and VX05-950-103) were included. These patients all received telaprevir monotherapy for 14 days, and 2 patients subsequently received standard of care. Variants at previously well-characterized NS3 protease positions V36, T54, R155 and A156 were assessed at baseline and after a follow-up of 4±1.2 years by ultra-deep pyrosequencing. The prevalence of resistant variants at follow-up was compared to baseline. Results Resistance associated mutations were detectable at low frequency at baseline. In general, prevalence of resistance mutations at follow-up was not increased compared to baseline. Only one patient had a small, but statistically significant, increase in the number of V36M and T54S variants 4 years after telaprevir-dosing. Conclusion In patients treated for 14 days with telaprevir monotherapy, ultra-deep pyrosequencing indicates that long-term persistence of resistant variants is rare.

Abstract
In November 2010, the Spanish Society of Liver Transplantation (Sociedad Española de Trasplante Hepático, SETH) held a consensus conference. One of the topics of debate was liver transplantation in patients with hepatitis C. This document reviews (i) the natural history of post-transplant hepatitis C, (ii) factors associated with post-transplant prognosis in patients with hepatitis C, (iii) the role of immunosuppression in the evolution of recurrent hepatitis C and response to antiviral therapy, (iv) antiviral therapy, both before and after transplantation, (v) follow-up of patients with recurrent hepatitis C and (vi) the role of retransplantation.

Abstract
In 2009, an association between the interleukin-28B (IL28B) polymorphism and treatment outcome for genotype 1 (G1) hepatitis C virus (HCV) infection, as well as spontaneous clearance of HCV, was reported. Since the initial publications, over 100 articles have appeared in the peer-reviewed literature, with many more manuscripts in press and abstracts presented at scientific meetings. Despite the proliferation of data concerning the IL28B polymorphism and HCV infection, there remain many critical unanswered questions about clinical implications and the underlying biological mechanisms. In this review, we discuss the basic principles of genome-wide association study methodologies that are important for interpreting the results of genetic association studies. We then review the current literature concerning the association between IL28B variants and interferon (IFN) treatment response in patients with chronic HCV infection, as well as spontaneous HCV clearance. We consider the relevance of the IL28B polymorphism to non-G1 HCV, as well as the special treatment populations of HIV/HCV co-infection and recurrent HCV post-liver transplantation. We review current knowledge of the biological mechanisms underlying this genetic association, including the link to liver IFN-stimulated gene expression, and identify continuing gaps in our knowledge and key research priorities. Finally, pegylated-IFN and ribavirin is no longer the standard of care for the treatment of G1 HCV, and we conclude by considering the relevance of IL28B polymorphisms in the era of direct-acting antivirals.

Abstract
In the immunocompetent setting, antiviral therapy-related anemia has recently been shown to be associated with a sustained virological response (SVR). Our goal was to assess whether this is also true for liver transplantation (LT). We included 160 LT patients with recurrent hepatitis C virus (HCV) who were treated with pegylated interferon and ribavirin (RBV) between 2002 and 2010; 76% of the patients were men, the median age of the patients was 56 years (range = 33-75 years), 63% had advanced fibrosis, and 86% were infected with HCV genotype 1a or 1b. The baseline immunosuppression was tacrolimus in 56% of the patients. Mycophenolate mofetil (MMF) was used in 15%. Anemia was defined as a hemoglobin (Hb) level < 10 g/dL. Significant anemia was present when the Hb decline was >5 g/dL. Anemia and significant anemia developed in 67% and 41% of the patients, respectively. Erythropoietin was used in 60%. Factors independently associated with significant anemia included low estimated creatinine clearance [relative risk (RR) = 0.951, 95% confidence interval (CI) = 0.925-0.978, P = 0.0001], a longer time from LT to therapy (RR = 1.001, 95% CI = 1.000-1.001, P = 0.002), high baseline viremia (RR = 3.2, 95% CI = 1.3-8.1, P = 0.01), cyclosporine A (CSA)-based immunosuppression (RR: 3.472, 95% CI: 1.386-8.695; P = 0.008), and the use of MMF (RR: 5.346, 95% CI: 1.398-20.447; P = 0.014). An SVR occurred in 43% of the patients; the factors associated with an SVR included baseline variables (younger recipient age, younger donor age, infections with non-1 HCV genotypes, body mass index, and mild fibrosis) and on-treatment factors related to adherence or viral kinetics. Anemia resulted in RBV dose reductions but was not associated with the virological response at any time. In conclusion, anemia is a very frequent complication in LT patients during antiviral therapy and is associated with increased RBV dose reduction but not with an SVR. Predictors of anemia include MMF or CSA immunosuppression, high viremia, and renal insufficiency.

Abstract
Chronic hepatitis C infection leads to increased hepatocyte apoptosis. Because engulfment of apoptotic bodies (ABs) by hepatic stellate cells (HSC) is profibrogenic, we compared the effects of ABs derived from hepatitis C virus (HCV)-negative vs HCV-infected (Con1+) Huh7 hepatoblastoma cells on fibrogenic and activation-related mRNA expression by a human HSC line (LX2). Uptake of Huh7(Con1+) ABs by LX2 cells dose dependently upregulated profibrotic genes (COL1A1, TGFB1; TIMP1; TIMP2). When normalized to the apoptotic cytokeratin-18 M30 neoepitope, HCV(+) ABs exhibited a more pronounced effect than HCV(-) ABs. In contrast, neither noningested ABs nor nucleic acids obtained from Huh7, Huh7(Con1+) or HepG2 cells triggered those AB-dependent effects. Both the engulfment of Huh7(Con1+) ABs and their effects were partially blocked by masking of phosphatidylserine with annexin V and completely inhibited by the class-A scavenger receptor ligand, polyinosinic acid. Our findings demonstrate that AB uptake stimulates HSCs and indicate that HCV infection leads to amplified fibrogenic mRNA expression and enhanced HSC activation.

Abstract
Chronic HCV infection is one of the leading causes of end-stage liver disease and hepatocellular carcinoma worldwide, and it constitutes one of the principal indications for liver transplant. However, recurrent HCV infection after liver transplant is nearly universal, and leads to decreased patient and graft survival in the long-term. Strategies to approach this problem that is commonly encountered in clinical practice include treating patients in order to obtain viral clearance before the transplant, pre-emptive treatment, which refers to therapy initiation before there is histological evidence of disease, and treatment for established recurrence. Therapy at these diverse time points poses varied challenges regarding the feasibility of the treatment, possibility of treatment completion, risk of adverse effects and different response rates. Furthermore, advances are being made in identifying prognostic markers of viral response, which could aid in decreasing the disease burden.

Abstract
BACKGROUND & AIMS Recent studies have described a major impact of genetic variations near the IL28B gene on the natural course and outcome of antiviral therapy in chronic hepatitis C. We therefore, aimed to explore the impact of donor and recipient genotypes of these polymorphisms on hepatitis C virus (HCV) liver graft reinfection. METHODS Donor and recipient genotypes of IL28B rs12979860C>T single nucleotide polymorphism were determined in 91 patients with HCV liver graft reinfection, 47 of whom were treated with pegylated interferon-α (PEG-IFN-α) and ribavirin. IL28B genetic polymorphisms were correlated with the natural course and treatment outcome of recurrent hepatitis C. RESULTS Patients requiring liver transplantation due to end-stage chronic hepatitis C appeared to be selected toward the adverse genotypes rs12979860 CT/TT compared to non-transplanted HCV-infected patients (p=0.046). Patients with the donor genotype rs12979860 CC had higher peak ALT and HCV RNA serum concentrations than those with CT/TT (p=0.04 and 0.06, respectively). No association was observed between ALT/HCV RNA serum concentrations and recipient genotypes (p>0.3). More important, donor IL28B rs12979860 CC vs. CT/TT genotypes were associated with rapid, complete early, and sustained virologic response (RVR, cEVR, SVR) to treatment with PEG-IFN-α and ribavirin (p=0.003, 0.0012, 0.008, respectively), but weaker associations of recipient genotypes with RVR, cEVR, and SVR were observed as well (p=0.0046, 0.115, 0.118, respectively). CONCLUSIONS We provide evidence for a dominant, but not exclusive impact of the donor rather than the recipient IL28B genetic background on the natural course and treatment outcome of HCV liver graft reinfection.

Abstract
BACKGROUND The ANA773 is an oral prodrug of a small-molecule toll-like receptor (TLR)7 agonist. Preclinical and healthy volunteer clinical studies with ANA773 have demonstrated induction of endogenous interferon-α (IFN-α) of multiple subtypes, which supports the potential utility in the treatment of chronic hepatitis C virus (HCV) infection. AIM To examine safety, tolerability, pharmacodynamics, pharmacokinetics and anti-viral activity of ANA773. METHODS The ANA773 was investigated in a double-blind, placebo-controlled study in 34 patients chronically infected with HCV of any genotype. Patients were treatment-naïve or had relapsed following previous interferon-based treatment. This dose escalation study was composed of four dose groups (800, 1200, 1600 and 2000mg). In each group, six to eight patients received ANA773 and two received placebo. Patients were dosed with ANA773 every-other-day for either 28 days (800, 1200 or 1600mg) or 10days (2000mg). RESULTS Mild to moderate adverse events were reported, with an increase in frequency and intensity with increasing dose. No serious AEs were reported and there were no early discontinuations. There were dose-related increases in various markers of IFN-α response. The mean maximum change in serum HCV RNA level from baseline was -0.34, -0.29, -0.40, -0.97 and -1.26log(10) in the placebo, 800, 1200, 1600 and 2000mg cohorts, respectively. At the 2000mg dose, ANA773 significantly (P=0.037) reduced serum HCV RNA levels (range: 0.14 to -3.10log(10) ). CONCLUSION The ANA773 was generally well tolerated and resulted in a dose-related IFN-dependent response leading to a significant decrease in serum HCV RNA levels in the 2000mg dose group.

Abstract
Hepatitis C virus (HCV) re-infection of the graft is universal and interferon based antiviral therapy remains at present the treatment of choice in HCV liver transplant recipients. Apart from the antiviral effects, interferon and ribavirin have both potent immunomodulatory properties resulting in a broad range of immune-related disorders including acute cellular rejection and chronic ductopenic rejection as well as de novo autoimmune hepatitis. Further complicating the picture, HCV infection per se is associated with a variety of autoimmune phenomena. We discuss here the immune-mediated complications and their relationship to chronic HCV and interferon based antiviral therapy.

Abstract
HCV has been classified into no fewer than six major genotypes and a series of subtypes. Each HCV genotype is unique with respect to its nucleotide sequence, geographic distribution, and response to therapy. Genotypes 1, 2, and 3 are common throughout North America and Europe. HCV genotype 4 (HCV-4) is common in the Middle East and in Africa, where it is responsible for more than 80% of HCV infections. It has recently spread to several European countries. HCV-4 is considered a major cause of chronic hepatitis, cirrhosis, hepatocellular carcinoma, and liver transplantation in these regions. Although HCV-4 is the cause of approximately 20% of the 170 million cases of chronic hepatitis C in the world, it has not been the subject of widespread research. Therefore, this document, drafted by a panel of international experts, aimed to review current knowledge on the epidemiology, natural history, clinical, histological features, and treatment of HCV-4 infections.

Abstract
UNLABELLED Factors present prior to liver transplantation (LT) that predict fibrosis progression in recurrent hepatitis C infection (HCV) after LT would be important to identify. This study sought to determine if histologic grade of HCV in the explant predicts fibrosis progression in recurrent HCV. The clinical and histologic data of all 159 patients undergoing their first LT for HCV at our center from 1998 to 2001 were retrospectively reviewed with follow-up through June 2008. Twenty-five cases were excluded for: non-HCV-related graft loss <90 days (19), recidivism (4), or unavailable explant or follow-up biopsies (2). A single pathologist scored (Ishak) explants in a blinded fashion. Patients were grouped by explant inflammatory grade ≤ 4 (group1) and >4 (group 2). Prospectively scored liver biopsies (protocol months 1 and 4, annually, and as indicated clinically) were reviewed for development of advanced fibrosis (bridging or cirrhosis). Cox proportional hazard regression was used to analyze the association of explant grade, donor, viral and LT factors with progression to advanced fibrosis. The groups were well-matched for patient, viral, donor, and transplant factors. Five-year advanced fibrosis-free survival in group 1 versus group 2 was 63% versus 28%, P < 0.001. Explant grade >4 was associated with increased HCV-related graft loss at 1 (6% versus 3%) and 5 (36% versus 14%) years post-LT (P = 0.003). On univariate and multivariate Cox regression analysis, predictors of advanced fibrosis were explant grade >4 (hazard ratio [HR] = 3.3, 95% confidence interval [CI] = 1.9-5.6, P < 0.001) donor age >50 (HR = 3.3, 95% CI = 1.9-5.7, P < 0.001) and viral load at LT of >158,730 IU/mL (HR = 1.8, 95% CI = 1.05-3.1, P = 0.03). CONCLUSION Explant histologic grade can identify patients requiring more aggressive monitoring and intervention for HCV recurrence post-LT.

Abstract
BACKGROUND Cirrhosis developing during chronic infection with the hepatitis C virus (HCV) poses a risk of anticipated liver-related death, therefore representing a dominant indication to anti-HCV therapy. OBJECTIVE This review highlights the efficacy and safety of treatment of HCV infection in cirrhotic patients with respect to the clinical stage of the disease. METHODS The PubMed, MEDLINE, EMBASE, and Cochrane databases, as well as the conference proceedings from the annual meetings of the American Association for the Study of Liver Diseases, the European Association for the Study of the Liver, and the Asian Pacific Association for the Study of the Liver, were searched for articles published in English from January 1990 through May 2010, fulfilling the following criteria: (1) randomized, prospective observational, retrospective, or meta-analysis; (2) involving adult patients with chronic HCV infection; and (3) data (fibrosis stage, treatment regimen, efficacy, safety) available for cirrhotics. Reviews were excluded. Search terms included chronic hepatitis C, fibrosis, cirrhosis, interferon alfa, ribavirin, hepatocellular carcinoma, and liver decompensation. RESULTS Forty-five studies were identified. The rates of sustained virologic response to pegylated interferon in combination with ribavirin ranged from 10% to 44% for HCV genotypes 1/4 to 33% to 72% for genotypes 2/3 in compensated cirrhosis, while falling to 0% to 16% and 44% to 57%, respectively, in the decompensated stage, compared with 29% to 55% for genotypes 1/4 and 70% to 80% for genotypes 2/3 in noncirrhotic patients (compensated cirrhosis vs no cirrhosis: P < 0.001 for genotypes 1/4 and P = 0.002 for genotypes 2/3; decompensated cirrhosis vs no cirrhosis: P < 0.001 for all genotypes). HCV clearance was associated with a reduced risk of liver decompensation, hepatocellular carcinoma development, liver-related mortality, and hepatitis recurrence after liver transplantation. Treatment during compensated cirrhosis proved to be most cost-effective versus treatment after decompensation or a no-treatment strategy. Headache (54%), irritability (38%), fatigue (34%), and nausea (30%) were the most common adverse events in compensated patients, while anorexia (100%), fatigue (59%), neutropenia (53%), and thrombocytopenia (50%) were most common in decompensated patients. CONCLUSIONS Anti-HCV treatment in cirrhotic patients was less effective than in noncirrhotic patients. Viral eradication reduced the risk of liver complications and improved survival in noncirrhotics. Based on effectiveness and tolerability data, therapy has a significant effect in patients with compensated cirrhosis, while decompensated patients need to weigh the risks versus benefits of treatment.

Abstract
Hepatitis C virus (HCV) recurrence after orthotopic liver transplantation (LT) is universal. We designed a retrospective case-control study to evaluate the effect of mycophenolate mofetil (MMF) monotherapy in patients with recurrent hepatitis C. Fifteen patients with histologically proven hepatitis C recurrence after LT were switched from calcineurin inhibitors (CNIs) to MMF monotherapy because of impairment of kidney function and/or metabolic side effects, and treated for 48 months (MMF group). Fifteen well-matched LT recipients who continued to receive CNIs therapy over the same period served as control group. Demographics, clinical data, time after LT, and baseline liver biopsies were similar in the two groups. There was no worsening of hepatic fibrosis during the study in the MMF group [2.6 ± 1.5 (baseline) Ishak Units vs. 2.7 ± 1.8 (after 48 months of MMF treatment), P = 0.6]. In contrast, a significant increase in the fibrosis score [2 ± 1.1 (baseline) vs. 3.2 ± 1.7 (after 48 months of CNI treatment), P = 0.0002] was observed in the control group. The yearly fibrosis progression rate was of 0.05 ± 0.44 in the MMF group and 0.33 ± 0.24 in the CNI group (P = 0.04). MMF monotherapy is associated with a favourable effect on hepatic fibrosis progression in HCV liver transplant recipients.
