Abstract
Background and aims Interferon (IFN)- free direct antiviral agents (DAAs) with rapid HCV eradication might evoke immunological reconstitutions, and some early recurrences of HCC after IFN-free DAAs have been reported. This study aimed to investigate whether natural killer group 2, member D (NKG2D) predicts early emergence of HCC after IFN-free DAAs. Methods We conducted a clinical practice-based observational study of 101 patients infected with genotype 1 HCV who received IFN-free (DAAs), and stratified them into those who did or did not develop early (i.e., during the 6-month surveillance period following treatment.) recurrence or occurrence of clinically evident HCC. We also analyzed the peripheral blood mononuclear cells, both before treatment and at end of treatment (EOT), of 24 of the patients who received IFN-free DAAs, and 16 who received IFN-combined protease inhibitor. Results We found early emergence of clinically evident HCC after IFN-free DAAs in 12 (12%) patients. Higher pre-treatment NKG2D expression, higher FIB-4 score, previous HCC history and failure to achieve sustained viral response were significant factors correlating to early HCC emergence. After IFN-free DAAs, a rapid decrease of NKG2D at EOT correlated with early HCC emergence in the IFN-free DAA-treated patients, but not in patients treated with the IFN-combined regimen. The decrease of NKG2D until EOT was predictive of early HCC emergence at a cut-off of -52% (AUC = 0.92). Conclusions On-treatment decrease of NKG2D may be a useful predictor of early emerging HCC in patients treated with IFN-free DAAs.

Abstract
BACKGROUND Millions of people worldwide suffer from hepatitis C, which can lead to severe liver disease, liver cancer, and death. Direct-acting antivirals (DAAs) are relatively new and expensive interventions for chronic hepatitis C, and preliminary results suggest that DAAs may eradicate hepatitis C virus (HCV) from the blood (sustained virological response). However, it is still questionable if eradication of hepatitis C virus in the blood eliminates hepatitis C in the body, and improves survival and leads to fewer complications. OBJECTIVES To assess the benefits and harms of DAAs in people with chronic HCV. SEARCH METHODS We searched for all published and unpublished trials in The Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, MEDLINE, Embase, Science Citation Index Expanded, LILACS, and BIOSIS; the Chinese Biomedical Literature Database (CBM), China Network Knowledge Information (CNKI), the Chinese Science Journal Database (VIP), Google Scholar, The Turning Research into Practice (TRIP) Database, ClinicalTrials.gov, European Medicines Agency (EMA) (www.ema.europa.eu/ema/), WHO International Clinical Trials Registry Platform (www.who.int/ictrp), the Food and Drug Administration (FDA) (www.fda.gov), and pharmaceutical company sources for ongoing or unpublished trials. Searches were last run in October 2016. SELECTION CRITERIA Randomised clinical trials comparing DAAs versus no intervention or placebo, alone or with co-interventions, in adults with chronic HCV. We included trials irrespective of publication type, publication status, and language. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Our primary outcomes were hepatitis C-related morbidity, serious adverse events, and quality of life. Our secondary outcomes were all-cause mortality, ascites, variceal bleeding, hepato-renal syndrome, hepatic encephalopathy, hepatocellular carcinoma, non-serious adverse events (each reported separately), and sustained virological response. We systematically assessed risks of bias, performed Trial Sequential Analysis, and followed an eight-step procedure to assess thresholds for statistical and clinical significance. The overall quality of the evidence was evaluated using GRADE. MAIN RESULTS We included a total of 138 trials randomising a total of 25,232 participants. The 138 trials assessed the effects of 51 different DAAs. Of these, 128 trials employed matching placebo in the control group. All included trials were at high risk of bias. Eighty-four trials involved DAAs on the market or under development (13,466 participants). Fifty-seven trials administered withdrawn or discontinued DAAs. Trial participants were treatment-naive (95 trials), treatment-experienced (17 trials), or both treatment-naive and treatment-experienced (24 trials). The HCV genotypes were genotype 1 (119 trials), genotype 2 (eight trials), genotype 3 (six trials), genotype 4 (nine trials), and genotype 6 (one trial). We identified two ongoing trials.Meta-analysis of the effects of all DAAs on the market or under development showed no evidence of a difference when assessing hepatitis C-related morbidity or all-cause mortality (OR 3.72, 95% CI 0.53 to 26.18, P = 0.19, I² = 0%, 2,996 participants, 11 trials, very low-quality evidence). As there were no data on hepatitis C-related morbidity and very few data on mortality (DAA 15/2377 (0.63%) versus control 1/617 (0.16%)), it was not possible to perform Trial Sequential Analysis on hepatitis C-related morbidity or all-cause mortality.Meta-analysis of all DAAs on the market or under development showed no evidence of a difference when assessing serious adverse events (OR 0.93, 95% CI 0.75 to 1.15, P = 0.52, I² = 0%, 15,817 participants, 43 trials, very low-quality evidence). The Trial Sequential Analysis showed that the cumulative Z-score crossed the trial sequential boundary for futility, showing that there was sufficient information to rule out that DAAs compared with placebo reduced the relative risk of a serious adverse event by 20%. The only DAA that showed a significant difference on risk of serious adverse events when meta-analysed separately was simeprevir (OR 0.62, 95% CI 0.45 to 0.86). However, Trial Sequential Analysis showed that there was not enough information to confirm or reject a relative risk reduction of 20%, and when one trial with an extreme result was excluded, then the meta-analysis result showed no evidence of a difference.DAAs on the market or under development seemed to reduce the risk of no sustained virological response (RR 0.44, 95% CI 0.37 to 0.52, P < 0.00001, I² = 77%, 6886 participants, 32 trials, very low-quality evidence) and Trial Sequential Analysis confirmed this meta-analysis result.Only 1/84 trials on the market or under development assessed the effects of DAAs on health-related quality of life (SF-36 mental score and SF-36 physical score).Withdrawn or discontinued DAAs had no evidence of a difference when assessing hepatitis C-related morbidity and all-cause mortality (OR 0.64, 95% CI 0.23 to 1.79, P = 0.40, I² = 0%; 5 trials, very low-quality evidence). However, withdrawn DAAs seemed to increase the risk of serious adverse events (OR 1.45, 95% CI 1.22 to 1.73, P = 0.001, I² = 0%, 29 trials, very low-quality evidence), and Trial Sequential Analysis confirmed this meta-analysis result.Most of all outcome results were short-term results; therefore, we could neither confirm nor reject any long-term effects of DAAs. None of the 138 trials provided useful data to assess the effects of DAAs on the remaining secondary outcomes (ascites, variceal bleeding, hepato-renal syndrome, hepatic encephalopathy, and hepatocellular carcinoma). AUTHORS' CONCLUSIONS Overall, DAAs on the market or under development do not seem to have any effects on risk of serious adverse events. Simeprevir may have beneficial effects on risk of serious adverse event. In all remaining analyses, we could neither confirm nor reject that DAAs had any clinical effects. DAAs seemed to reduce the risk of no sustained virological response. The clinical relevance of the effects of DAAs on no sustained virological response is questionable, as it is a non-validated surrogate outcome. All trials and outcome results were at high risk of bias, so our results presumably overestimate benefit and underestimate harm. The quality of the evidence was very low.

Hepatitis B virus reactivation among hepatitis C patients treated with direct-acting antiviral therapies in routine clinical practice. J Clin Virol 2017; 93:66-70. [PMID: 28654775 DOI: 10.1016/j.jcv.2017.05.021] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2017] [Revised: 05/22/2017] [Accepted: 05/30/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND Hepatitis B (HBV) reactivation in chronic hepatitis C (CHC) patients treated with IFN-free direct acting antiviral (DAA) therapies has recently emerged as a potential risk. Given the potential burden of this issue, further data are needed to establish its actual clinical impact. OBJECTIVES The aim of the present study was to analyze the occurrence of HBV reactivation in a cohort of CHC patient treated with DAAs in routine clinical practice. STUDY DESIGN Consecutive CHC patients with different genotypes, treated with DAA between January 2015 and January 2016 were included in the study. Subjects had been tested for HBsAg and anti-HBc antibodies before antiviral therapy. HBV-DNA levels were examined in anti-HBc positive patients at baseline and 24 weeks after the end of treatment. Post-treatment HBsAg determination was performed in case of HBV-DNA positivity. Serum anti-HBs kinetics was analysed in anti-HBs and anti-HBc positive subjects. RESULTS A cohort of 137 consecutive HCV patients treated with IFN-free regimens in routine clinical practice was evaluated. From this cohort, plasma samples of 44 subjects with positive serology for HBV (anti-HBc positive) were tested for HBV-DNA levels at baseline and 24 weeks after the end of treatment. Two of them were HBsAg-positive, while the others had signs of a past HBV exposure (HBsAg-negative±HBsAb-positive). No reactivation was found in HBcAb-positive and HBsAg-negative subjects. In the two HBsAg-positive, one experienced an increase in HBV-DNA levels of ≥2 log10 IU/mL during treatment. However, the reactivation was without clinical impact and, most important, was followed by HBsAg loss. CONCLUSIONS Based on our experience, a past HBV infection seems not to be a condition predisposing to HBV reactivation. On the contrary, in HBsAg-positive subjects not in suppressive treatment with nucleos(t)ide analogs, regular monitoring of HBV-DNA during and after DAA treatment should be considered.

Abstract
Therapy of hepatitis C has been revolutionized by Direct Antiviral Agents. These drugs are safe and efficacious in all infected patients, including those with advanced, or decompensated cirrhosis, and are currently largely used in such cases in clinical practice worldwide. It was therefore cause of great concern the publication of two reports suggesting that treatment with DAAs could increase the risk of hepatocellular carcinoma in cirrhotic patients, particularly in those receiving antiviral therapy after having been cured for an HCC. These reports have generated a great and controversial debate and have been followed by a series of other publications not confirming such increased risk. This article summarizes published studies assessing the relation between DAA therapy and HCC in two different clinical setting: HCC recurrence in patients with an history of cured HCC and "de novo" HCC occurrence in patients without previous HCC. Rates of HCC recurrence after DAAs were extremely variable in different studies, reflecting great heterogeneity of this clinical setting. Data on "de novo" HCC incidence were more homogeneous and suggest that treatment with DAAs is not modifying the risk of developing HCC in the first 6-12 months. The possibility that treatment with DAAs may favour tumour growth and spread in individual patients with active HCC foci is suggested by some observations but remains unproven. There is clearly a need for prospective studies designed to better define these issues.

Abstract
BACKGROUND We investigated the real-world effectiveness of interferon-free regimens for the treatment of patients with compensated cirrhosis infected with hepatitis C virus (HCV). METHOD Using the Irish national HCV treatment registry, the effectiveness and safety of interferon-free regimens for HCV-infected patients treated between April 2015 and August 2016, was determined. RESULTS A SVR12 was achieved in 86% of subjects treated with sofosbuvir/ledipasvir ± ribavirin (SOF/LDV±RBV), 93% treated with paritaprevir, ombitasvir and ritonavir combined with dasabuvir ± ribavirin (3D±RBV) and 89% treated with sofosbuvir/daclatasvir ± ribavirin (SOF/DCV±RBV). The discontinuation rate was 5% and the on-treatment mortality rate was 1%. CONCLUSION The availability of interferon-free regimens represents a significant breakthrough for the treatment of HCV infection. Treatments options, with high SVR12 rates, are now available for patients with compensated cirrhosis who were unsuitable for treatment with interferon-based regimens. Data obtained from studies conducted in real world practice provide robust information fundamental for input into future economic evaluations for agents used for the treatment of HCV infection.

Abstract
The goals of treatment is to eliminate HCV infection, stop or reverse histological changes, reduce the risk of hepatocellular carcinoma development and transmission of the infection to other individuals. According to the recommendation of the Polish Group of Experts for HCV in 2017 all patients with chronic HCV infection should receive treatment, but it is not recommended in patients at high risk of short overall survival. If access to therapy is restricted, priority should be given to patients whose HCV infection can lead to an unfavourable outcome of the disease within a short time frame, particular to individuals with liver cirrhosis, rapidly progressing liver fibrosis, extrahepatic manifestations of HCV infection, chronic kidney diseases, patients before and after organ transplantation. Current recommendations of Polish Group of Experts for HCV provide guidelines to select optimal medication, assessment of liver fibrosis, treatment efficacy, dealing with resistance to direct acting antivirals, monitoring for hepatocellular carcinoma, management of HBV/HCV coinfection and drug interactions. It constains also advice on treatment of special patients populations such as renal failure, liver transplant and hepatic decompensation, as well as retreatment of patients which failed interferon free therapy. Moreover specific recommendations of management patients infected with different genotypes with currently reimbursed regimens or those expected to become available shortly in Poland are also included.

Effectiveness, safety and clinical outcomes of direct-acting antiviral therapy in HCV genotype 1 infection: Results from a Spanish real-world cohort. J Hepatol 2017; 66:1138-1148. [PMID: 28189751 DOI: 10.1016/j.jhep.2017.01.028] [Citation(s) in RCA: 142] [Impact Index Per Article: 20.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2016] [Revised: 01/25/2017] [Accepted: 01/29/2017] [Indexed: 02/08/2023]
Abstract
BACKGROUND & AIMS Clinical trials evaluating second-generation direct-acting antiviral agents (DAAs) have shown excellent rates of sustained virologic response (SVR) and good safety profiles in patients with chronic hepatitis C virus (HCV) genotype 1 infection. We aimed to investigate the effectiveness and safety of two oral DAA combination regimens, ombitasvir/paritaprevir/ritonavir plus dasabuvir (OMV/PTV/r+DSV) and ledipasvir/sofosbuvir (LDV/SOF), in a real-world clinical practice. METHODS Data from HCV genotype 1 patients treated with either OMV/PTV/r+DSV±ribavirin (RBV) (n=1567) or LDV/SOF±RBV (n=1758) in 35 centers across Spain between April 1, 2015 and February 28, 2016 were recorded in a large national database. Demographic, clinical and virological data were analyzed. Details of serious adverse events (SAEs) were recorded. RESULTS The two cohorts were not matched with respect to baseline characteristics and could not be compared directly. The SVR12 rate was 96.8% with OMV/PTVr/DSV±RBV and 95.8% with LDV/SOF±RBV. No significant differences were observed in SVR according to HCV subgenotype (p=0.321 [OMV/PTV/r+DSV±RBV] and p=0.174 [LDV/SOF]) or degree of fibrosis (c0.548 [OMV/PTV/r/DSV±RBV] and p=0.085 [LDV/SOF]). Only baseline albumin level was significantly associated with failure to achieve SVR (p<0.05) on multivariate analysis. Rates of SAEs and SAE-associated treatment discontinuation were 5.4% and 1.7%, in the OMV/PTV/r+DSV subcohort and 5.5% and 1.5% in the LDV/SOF subcohort, respectively. Hepatocellular carcinoma (HCC) recurred in 30% of patients with a complete response to therapy for previous HCC. Incident HCC was reported in 0.93%. CONCLUSIONS In this large cohort of patients managed in the real-world setting in Spain, OMV/PTV/r+DSV and LDV/SOF achieved high rates of SVR12, comparable to those observed in randomized controlled trials, with similarly good safety profiles. LAY SUMMARY In clinical trials, second-generation direct-acting antiviral agents (DAAs) have been shown to cure over 90% of patients chronically infected with the genotype 1 hepatitis C virus and have been better tolerated than previous treatment regimens. However, patients enrolled in clinical trials do not reflect the real patient population encountered in routine practice. The current study, which includes almost 4,000 patients, demonstrates comparable rates of cure with two increasingly used DAA combinations as those observed in the clinical trial environment, confirming that clinical trial findings with DAAs translate into the real-world setting, where patient populations are more diverse and complex.

Abstract
We compared the background characteristics of patients with chronic hepatitis C who achieved eradication of hepatitis C virus (HCV), that is sustained virologic response (SVR), with interferon (IFN)-based versus IFN-free antiviral therapy in Japan. In addition, we used a previously reported risk assessment model to compare the incidence of hepatocellular carcinoma (HCC) after SVR by treatment type. Pretreatment characteristics of 1533 patients who achieved SVR with IFN-based therapy and 1086 patients with IFN-free therapy from five institutions across Japan were compared. The risk of HCC after SVR was assessed based on pretreatment characteristics, and the incidence of HCC after SVR was estimated in both groups. Age and serum alpha-fetoprotein levels were higher, platelet count was lower, and liver fibrosis was more advanced in patients who achieved SVR with IFN-free therapy compared with IFN-based therapy. The incidence of HCC after SVR in the IFN-free group was estimated to be more than twofold higher than in the IFN-based therapy group (7.29% vs. 3.09%, and 6.23% vs. 3.01% when excluding patients who have underwent curative treatment for HCC). There are large differences in pretreatment characteristics between patients who achieved SVR with IFN-based and IFN-free therapies in Japan, which are associated with differential risk of HCC after SVR. These differences can influence the incidence of HCC after SVR and should be taken into consideration when comparing IFN-based and IFN-free therapies in terms of hepatocarcinogenesis suppression with HCV eradication.

Abstract
BACKGROUND & AIMS Few patients from developing countries can afford brand name direct-acting antiviral agents for treating hepatitis C virus (HCV) infection, and controversy regarding the bioequivalence of generics exists. This study aimed to observe the safety and efficacy of 8 or 12weeks of generic ledipasvir-sofosbuvir with or without ribavirin for Chinese genotype 1b HCV-infected patients. METHODS In this open-labelled observational study, 63 cirrhotic (group 1) and 65 non-cirrhotic (group 2) patients were administered generic ledipasvir-sofosbuvir plus 1000-1200mg of ribavirin daily for 12 and 8weeks, respectively; and 64 non-cirrhotic patients (group 3) received ledipasvir-sofosbuvir for 8weeks. The primary efficacy endpoint was undetectable HCV RNA at week 12 (SVR12) after cessation of therapy. Safety and pharmacokinetic data were collected. RESULTS One hundred and eighty-seven patients completed treatment, and the latest undetectable HCV RNA was observed in three patients with cirrhosis at week 5 during treatment. Intention-to-treat analysis revealed 96.8% (61/63), 96.9% (63/65), and 96.9% (62/64) of SVR12 rates in groups 1, 2, and 3, respectively. One patient in group 3 relapsed at post-treatment week 4. The regimens were generally well-tolerated. The most common adverse events were fatigue (17.8%), diarrhea (10.9%), and headache (9.9%). Four patients discontinued therapy due to diarrhea and vomiting. One patient from group 2 discontinued treatment on day 29 because of drug-unaffordability; fortunately, she achieved SVR12. CONCLUSION This study demonstrated that 8 or 12weeks of generic ledipasvir-sofosbuvir with or without ribavirin are safe and effective for patients with genotype 1b HCV infection. LAY SUMMARY The price of Harvoni® has led to restrictions and access limitations in many developing and even developed countries with limited healthcare budgets. Gilead approved generic ledipasvir-sofosbuvir costs far less than Harvoni® and presents a similar cure rate for patients with chronic hepatitis C.

Abstract
The availability of direct-acting antiviral agents (DAA) regimens has expanded the pool of patients eligible for treatment. However, data on the virologic response and tolerability of DAAs in elderly patients are lacking. We evaluated the efficacy and safety of DAAs in patients with advanced fibrosis/cirrhosis in real-life practice with the focus on those aged ≥65 years. Between January and December 2015, all consecutive patients with HCV-related advanced fibrosis/cirrhosis treated with DAA at eleven tertiary referral centres in Emilia Romagna (Italy) were enrolled. Regimen choice was based on viral genotype and stage of disease, according to guidelines. The primary end point was sustained virologic response 12 weeks after the end of treatment (SVR12). Overall, 282 of 556 (50.7%) patients evaluated were elderly, most of them with cirrhosis. Antiviral therapy was stopped prematurely in four (1.4%) patients. Two patients, both with cirrhosis, died during treatment due to worsening of liver/renal function. SVR12 was achieved by 94.7% and was comparable to that obtained in patients aged <65 (P=.074). Similar data were also reported in subgroup of patients aged ≥75 years. All patients with advanced fibrosis achieved virologic response. SVR12 was 80.8% in Child-Pugh-Turcotte (CTP)-B cirrhosis and 95.4% in CTP-A (P=.013). According to genotype, the SVR12 was achieved in 172 of 181 (95%) with genotype 1b cirrhosis and in 44 of 48 (91.7%) with genotype 2 cirrhosis. In conclusions, in a real-world setting, DAAs are safe and effective in elderly patients with HCV-related advanced fibrosis/cirrhosis, but SVR12 is lower with worsening CTP class.

Abstract
From 2010, the landscape of hepatitis C therapeutics has been changed rapidly, and today we are standing at a cusp of a pharmacological revolution where highly effective and interferon (IFN)-free direct acting antivirals (DAAs) are already on the market. Such treatment paradigms attain 90-95% sustained virologic response (SVR; undetectable viral load at week 12 or 24 at the end of therapy) rates in treated individuals compared to 50-70% with treatment completion of dual-therapy-pegylated interferon (PEG-IFN) and ribavirin (RBV). As the major goal now for the hepatologists, clinicians, physicians, and health care workers is likely to eradicate hepatitis C infection in parallel to treatment, the demand is for a one-size-fits-all pill that could be prescribed beyond the limitations of hepatitis C genotype, viral load, previous treatment history, advanced hepatic manifestations (fibrosis, cirrhosis) and antiviral drug resistance. Although the new treatment strategies have shown high cure rates in clinical trials, such treatment paradigms are posing dilemmas too in real-world clinical practice. Therapy cost, treatment access to low and middle-income countries, treatment-emergent adverse events, lack of effective viral screening and disease progression simulation models are potential challenges in this prospect. This review article deeply overviews the challenges encountered while surmounting the burden of hepatitis C around the world.

Abstract
Hepatocellular carcinoma (HCC) develops on the background of liver cirrhosis often from multiple, simultaneous factors. The diagnosis of a single small HCC comes with good prognosis and provides a potential for cure. In contrast, the diagnosis of multifocal, large HCC has high mortality and poor prognosis. Unfortunately, the majority of HCC is diagnosed at such late stages. A surveillance program endorsed by regional liver societies involves six-monthly ultrasound surveillance of at-risk patients. This had been in action for the last two decades. It has led to marked increase in the proportion of patients presenting with small unifocal nodules found on surveillance. The development of tools to enhance our ability in optimizing available surveillance is likely to improve the prognosis of patients with HCC. In this review, we discuss the difficulties in utilizing HCC surveillance and possible means of improvement.

Abstract
OBJECTIVE Up to now, little was known about the immunological changes of chronic hepatitis C (CHC) patients treated with direct-acting antiviral agents (DAAs); we try to explore the effect of DAAs on the frequency of monocytes, NK cells, and cytokines that promote their activation. METHODS 15 treatment-naive CHC patients and 10 healthy controls were recruited. Patients were examined before DAAs therapy (0 w) and at week 4 (4 w) and week 12 (12 w) of therapy. Percentage of monocytes and NK cells of the peripheral blood was analyzed by flow cytometry. Serum cytokines IL-12, IL-18, CXCL10, CXCL11, sCD14, and sCD163 were measured by enzyme linked immunosorbent assay. RESULTS The frequency of CD3-CD16+CD56+ NK cells and classic CD14++CD16- monocytes decreased, while CD14+CD16+ monocytes and cytokines IL-12, IL-18, CXCL10, CXCL11, sCD14, and sCD163 increased at 0 w compared to healthy controls. During DAAs treatment, the decreased NK cells and classic monocytes gradually increased to normal levels; the increased inflammatory monocytes and cytokines IL-12 and CXCL11 decreased to normal levels, but the increased cytokines IL-18, CXCL10, sCD14, and sCD163 still remained at high levels at 12 w though they decreased rapidly from 0 w. CONCLUSION Our results showed that DAAs treatment attenuated the activation of monocytes and NK cells in CHC patients. Trial registration number is NCT03063723.

Abstract
Chronic hepatitis C virus infection is well-recognized as a common blood-borne infection with global public health impact affecting 3 to 5 million persons in the United States and more than 170 million persons worldwide. Chronic hepatitis C virus infection is associated with significant morbidity and mortality due to complications of liver cirrhosis and hepatocellular carcinoma. Current therapies with all-oral direct-acting antiviral agents are associated with high rates of sustained virologic response (SVR), generally exceeding 90%. SVR is associated with a reduced risk of liver cirrhosis, hepatic decompensation, need for liver transplantation, and both liver-related and all-cause mortality. However, a subset of patients who achieve SVR will remain at long-term risk for progression to cirrhosis, liver failure, hepatocellular carcinoma, and liver-related mortality. Limited evidence is available to guide clinicians on which post-SVR patients should be monitored vs discharged, how to monitor and with which tests, how frequently should monitoring occur, and for how long. In this clinical practice update, available evidence and expert opinion are used to generate best practice recommendations on the care of patients with chronic hepatitis C virus who have achieved SVR.

Abstract
BACKGROUND & AIMS The proportion of HCV-infected patients over age 65 years in Western countries is increasing. This growth and the advent of new antiviral therapy bring into the question the real-world efficacy and safety of the combination of sofosbuvir (SOF) and simeprevir (SMV) plus a flat dose of 800 mg/d ribavirin (RBV) in elderly patients with cirrhosis compared to younger patients. METHODS Retrospective observational multicentre real-life investigation study of SOF/SMV/RBV for a duration of 12 weeks in HCV genotype 1-infected patients with cirrhosis. RESULTS Of the 270 patients enrolled in this study, with compensated cirrhosis, 133 (49.2%) were ≥65 years of age. Sustained virological response at 12 weeks (SVR12) was achieved by 94.2% (129/137) of those aged <65 years and 97.7% (130/133) of those ≥65 years. Diabetes was the most common comorbidity in patients ≥65 years compared to younger patients (26.3% vs 12.4% P<.003). The most common adverse event (AE) in elderly patients was a grade 2 anaemia (35.3% vs 19.9% P<.004). CONCLUSIONS Sofosbuvir/simeprevir plus a daily flat dose of RBV 800 mg for 12 weeks was highly effective and safe in genotype 1 elderly patients with compensated cirrhosis.

Internal Disequilibria and Phenotypic Diversification during Replication of Hepatitis C Virus in a Noncoevolving Cellular Environment. J Virol 2017; 91:JVI.02505-16.

Abstract
Viral quasispecies evolution upon long-term virus replication in a noncoevolving cellular environment raises relevant general issues, such as the attainment of population equilibrium, compliance with the molecular-clock hypothesis, or stability of the phenotypic profile. Here, we evaluate the adaptation, mutant spectrum dynamics, and phenotypic diversification of hepatitis C virus (HCV) in the course of 200 passages in human hepatoma cells in an experimental design that precluded coevolution of the cells with the virus. Adaptation to the cells was evidenced by increase in progeny production. The rate of accumulation of mutations in the genomic consensus sequence deviated slightly from linearity, and mutant spectrum analyses revealed a complex dynamic of mutational waves, which was sustained beyond passage 100. The virus underwent several phenotypic changes, some of which impacted the virus-host relationship, such as enhanced cell killing, a shift toward higher virion density, and increased shutoff of host cell protein synthesis. Fluctuations in progeny production and failure to reach population equilibrium at the genomic level suggest internal instabilities that anticipate an unpredictable HCV evolution in the complex liver environment.IMPORTANCE Long-term virus evolution in an unperturbed cellular environment can reveal features of virus evolution that cannot be explained by comparing natural viral isolates. In the present study, we investigate genetic and phenotypic changes that occur upon prolonged passage of hepatitis C virus (HCV) in human hepatoma cells in an experimental design in which host cell evolutionary change is prevented. Despite replication in a noncoevolving cellular environment, the virus exhibited internal population disequilibria that did not decline with increased adaptation to the host cells. The diversification of phenotypic traits suggests that disequilibria inherent to viral populations may provide a selective advantage to viruses that can be fully exploited in changing environments.

Abstract
OPINION STATEMENT Chronic hepatitis C (HCV) is a hepatotropic virus which, when untreated, can lead to progressive inflammation and fibrosis resulting in cirrhosis, hepatocellular carcinoma (HCC), and decompensations related to end-stage liver disease. The relatively recent introduction of all oral, interferon-free, direct-acting antiviral medications against HCV has transformed the management of these patients. Previous treatment regimens were prolonged, poorly tolerated, and frequently did not result in cure. Current therapies achieve sustained viral response (SVR) in the vast majority of patients including those with decompensated liver disease; a previously challenging population to treat. These successes will result in significant numbers of cirrhotic patients requiring management after SVR. Although many complications of cirrhosis are improved in this setting, regular follow-up of HCC, esophageal varices, and other sequelae of cirrhosis will be necessary. This chapter will review the management of cirrhosis in HCV patients achieving cure.

Abstract
The concept of ‘cirrhosis’ is evolving and it is now clear that compensated and decompensated cirrhosis are completely different in terms of prognosis. Furthermore, the term ‘advanced chronic liver disease (ACLD)’ better reflects the continuum of histological changes occurring in the liver, which continue to progress even after cirrhosis has developed, and might regress after removing the etiological factor causing the liver disease. In compensated ACLD, portal hypertension marks the progression to a stage with higher risk of clinical complication and requires an appropriate evaluation and treatment. Invasive tests to diagnose cirrhosis (liver biopsy) and portal hypertension (hepatic venous pressure gradient measurement and endoscopy) remain of crucial importance in several difficult clinical scenarios, but their need can be reduced by using different non-invasive tests in standard cases. Among non-invasive tests, the accepted use, major limitations and major benefits of serum markers of fibrosis, elastography and imaging methods are summarized in the present review.

Abstract
Therapy with genetically modified autologous T cells has shown great promise in cancer therapy. For an efficient control of hepatitis C virus (HCV) infection, cytotoxic T cells (CTL) are pivotal, but persistence of activated T cells may lead to liver toxicity. Here, anti-HCV T cell receptors (TCRs) recognizing the HCV nonstructural (NS) NS3 or NS5 viral peptide target were examined by mRNA transfection of human peripheral blood lymphocytes (PBLs) derived from healthy donors as well as chronically infected HCV patients. Immunological analysis shows that while the CTLs expressing the NS5-specific TCR reduced HCV RNA replication by a noncytotoxic mechanism, the NS3-specific TCR-redirected CTLs were polyfunctional and inhibited HCV RNA replication through antigen-specific cytotoxicity. Transcriptome signatures from these two types of CTL responses revealed uniquely expressed gene clusters upon encountering hepatoma target cells presenting endogenously expressed HCV proteins. The NS3 TCR induced a rapid expression of apoptotic signaling pathways and formation of embryonic gene clusters, whereas the NS5A TCR activation induced extended proliferative and metabolic pathways as the HCV target cells survived. Our results provide detailed insights into basic HCV T cell immunology and have clinical relevance for redirecting T cells to target virally infected hepatoma cells.IMPORTANCE Due to the protective ability of HCV-specific T cells and the hepatotoxic potential that they possess, there is a great need for the understanding of the functional aspects of HCV-specific T cells. To circumvent the low level of precursor frequency in patients, we engineered primary CD8+ T cells by mRNA TCR vectors to confer HCV specificity to new T cells. HCV TCRs that differ in antigen specificity and polyfunctionality were examined. mRNA TCR engineering of peripheral blood lymphocytes from healthy donors or chronically infected HCV patients resulted in strikingly high levels of HCV TCR expression and HCV-specific responses. While a cytotoxicity response from a polyfunctional T cell activation caused hepatotoxicity and the rapid induction of apoptotic signaling pathways, the noncytotoxic T cell activation showed extended proliferative, metabolic pathways and persistence of HCV target cells. Our results provide detailed insights into basic HCV T cell immunology and have clinical relevance for immune protection of HCV-associated diseases.

Abstract
OBJECTIVES Direct acting antivirals (DAA) are extremely effective to treat chronic hepatitis C. The aim of this study was to evaluate, by using objective variables, the safety of DAA combinations under clinical practice conditions. METHODS A retrospective study was carried out in mono-infected patients with chronic hepatitis C treated with DAA between January and December 2015 in our centre. Discontinuations, treatment modifications, deaths and laboratory parameters were studied (liver function tests, hemoglobin, creatinine and lipid profile at baseline, weeks 4, 8 and post 12). Temporal variation of laboratory parameters was analyzed by t-test for paired data, and comparison between groups was made by t-test for independent samples and ANOVA. RESULTS 227 patients were included (40.5% cirrhotic). Sustained virological response (SVR) was achieved in 97.3% of patients. In only one case was the antiviral medication suspended due to toxicity, and there were no voluntary treatment discontinuations. The use of ribavirin (RBV) was associated with mild transient hyperbilirubinemia (41.2%) and anemia (32.6%, with RBV dose reduction in 7.9% of cases). There was an elevation in total cholesterol and LDL-cholesterol (LDL-C) during and after treatment: mean increase of 23 mg/dL (0.59 mmol/L) and 22 mg/dL (0.57 mmol/L), respectively in post 12 (p < .0001). An increment of 20% of patients with cholesterol levels over optimal figures was observed after DAA completion. CONCLUSION DAA have an optimum safety profile in real life conditions, with infrequent discontinuation and minor laboratory alterations.

Abstract
Liver transplantation for hepatocellular carcinoma (HCC) is the best treatment option for patients with early-stage tumours and accounts for ∼20-40% of all liver transplantations performed at most centres worldwide. The Milan criteria are the most common criteria to select patients with HCC for transplantation but they can be seen as too restrictive. Several proposals have been made for a moderate expansion of the criteria, which result in good outcomes but with an increase in the risk of tumour recurrence. In this Review, we provide a comprehensive overview of the outcomes after liver transplantation for HCC, focusing on tumour recurrence in terms of surveillance, prevention and treatment. Additionally, novel surgical techniques have been developed to increase the available pool of organs for liver transplantation (such as living donor liver transplantation, donation after circulatory death and split livers), but the effect of these techniques on patients with HCC is still under debate. Thus, we will describe these techniques and expose the benefits and disadvantages of each surgical approach. Finally, we will comment on the limitations of the current priority policies for liver transplantation and the need to further refine them to better serve the population.

Abstract
BACKGROUND A few cases of hepatitis B virus (HBV) reactivation during anti-viral therapy against hepatitis C (HCV) have been reported. However, the information regarding the real impact of this phenomenon is scarce. AIM To evaluate the risk of HBV reactivation during anti-viral therapy against HCV with an interferon-free regimen with direct-acting anti-virals (DAAs). METHODS Observational and prospective study of 352 patients receiving DAAs therapy between September 2015 and May 2016. HBV-DNA and ALT levels were monitored at baseline, at week 4 of anti-viral therapy, at end of treatment and 12 weeks after treatment discontinuation in patients with HBV surface antigen (HBsAg) positive or HBV core antibody (anti-HBc) positive before starting anti-viral therapy. RESULTS Ten (2.8%) and 64 (18%) patients were HBsAg and anti-HBc positive at baseline, respectively. Five (50%) of 10 HBsAg positive and one (1.6%) of 64 anti-HBc positive patients presented HBV virological reactivation (>1log increase in HBV-DNA levels). None of these patients presented clinical reactivation (increase in ALT levels). CONCLUSIONS HBV virological reactivation is frequent in HBsAg+ patients receiving anti-viral therapy against HCV. However, HBV-DNA elevations were modest (<20 000 IU/mL) and without clinical impact (no ALT elevation).

Abstract
Chronic hepatitis C (HCV) infection remains a major public health problem with many infected individuals worldwide. The revolutionary discovery of highly effective direct-acting antivirals (DAAs) makes chronic HCV infection a curable disease, even in patients with advanced liver disease. Liver function may improve shortly after initiation of antiviral therapy in patients on the waiting list and could even obviate the need for transplantation. However, whether these short term benefits also result in a favorable prognosis on the long-term remains to be seen and this fuels the discussion whether DAAs should be used prior to liver transplantation in all patients. Following liver transplantation, DAA treatment is also highly effective so that postponing antiviral treatment to the post-transplant setting may be better for certain patients. Furthermore, the discussion whether HCV positive organ donors should be used now viral eradication is achieved in almost all patients has regained interest.

Abstract
The mechanism why hepatitis C virus (HCV) clearance by direct-acting antivirals (DAAs) does not eliminate the risk of hepatocellular carcinoma (HCC) among patients with advanced cirrhosis is unclear. Many viral and bacterial infections degrade p53 in favor of cell survival to adapt an endoplasmic reticulum (ER)-stress response. In this study, we examined whether HCV clearance by interferon-alpha or DAAs normalizes the ER stress and restores the expression of p53 tumor suppressor in cell culture. We found that HCV infection induces chronic ER stress and unfolded protein response in untransformed primary human hepatocytes. The unfolded protein response induces chaperone-mediated autophagy (CMA) in infected primary human hepatocytes and Huh-7.5 cells that results in degradation of p53 and induced expression of mouse double minute 2 (Mdm2). Inhibition of p53/Mdm2 interactions by small molecule (nutlin-3) or silencing Mdm2 did not rescue the p53 degradation, indicating that HCV infection induces degradation of p53 independent of the Mdm2 pathway. Interestingly, we found that HCV infection degrades p53 in a lysosome-dependent mechanism because lysosome-associated membrane protein 2A silencing restored p53 degradation. Our results show that HCV clearance induced by interferon-alpha-based antiviral therapies normalizes the ER-stress response and restores p53, whereas HCV clearance by DAAs does neither. We show that decreased expression of p53 in HCV-infected cirrhotic liver is associated with expression of chaperones associated with ER stress and the CMA response. Conclusion: HCV-induced ER stress and CMA promote p53 degradation in advanced liver cirrhosis. HCV clearance by DAAs does not restore p53, which provides a potential explanation for why a viral cure by DAAs does not eliminate the HCC risk among patients with advanced liver disease. We propose that resolving the ER-stress response is an alternative approach to reducing HCC risk among patients with cirrhosis after viral cure. (Hepatology Communications 2017;1:256-269).

Abstract
Hepatitis C virus infection is a major cause of hepatocellular carcinoma worldwide. Interferon has been the major antiviral treatment, yielding viral clearance in approximately half of patients. New direct-acting antivirals substantially improved the cure rate to above 90%. However, access to therapies remains limited due to the high costs and under-diagnosis of infection in specific subpopulations, e.g., baby boomers, inmates, and injection drug users, and therefore, hepatocellular carcinoma incidence is predicted to increase in the next decades even in high-resource countries. Moreover, cancer risk persists even after 10 years of viral cure, and thus a clinical strategy for its monitoring is urgently needed. Several risk-predictive host factors, e.g., advanced liver fibrosis, older age, accompanying metabolic diseases such as diabetes, persisting hepatic inflammation, and elevated alpha-fetoprotein, as well as viral factors, e.g., core protein variants and genotype 3, have been reported. Indeed, a molecular signature in the liver has been associated with cancer risk even after viral cure. Direct-acting antivirals may affect cancer development and recurrence, which needs to be determined in further investigation.

Abstract
Liver-related morbidity and mortality is expanding in people living with HIV. Hepatocellular carcinoma (HCC), the third most lethal malignancy on a global scale, is a dominant complication of chronic liver disease and cirrhosis in patients with coexisting hepatitis. HIV infection further complicates the clinical heterogeneity of HCC, posing concurrent challenges stemming from the underlying immunological status of the patients and the ongoing need for combined antiretroviral therapy. In this article, we review the multiple clinical implications that characterize the multidisciplinary management of HCC in the context of HIV infection.

Future of liver disease in the era of direct acting antivirals for the treatment of hepatitis C. World J Hepatol 2017; 9:352-367.

Abstract
Hepatitis C virus (HCV) infection has been a global health problem for decades, due to the high number of infected people and to the lack of effective and well-tolerated therapies. In the last 3 years, the approval of new direct acting antivirals characterized by high rates of virological clearance and excellent tolerability has dramatically improved HCV infection curability, especially for patients with advanced liver disease and for liver transplant recipients. Long-term data about the impact of the new direct acting antivirals on liver fibrosis and liver disease-related outcomes are not yet available, due to their recent introduction. However, previously published data deriving from the use of pegylated-interferon and ribavirin lead to hypothesizing that we are going to observe, in the future, a reduction in mortality and in the incidence of hepatocellular carcinoma, as well as a regression of fibrosis for people previously affected by hepatitis C. In the liver transplant setting, clinical improvement has already been described after treatment with the new direct acting antivirals, which has often led to patients delisting. In the future, this may hopefully reduce the gap between liver organ request and availability, probably expanding liver transplant indications to other clinical conditions. Therefore, these new drugs are going to change the natural history of HCV-related liver disease and the epidemiology of HCV infection worldwide. However, the global consequences will depend on treatment accessibility and on the number of countries that could afford the use of the new direct acting antivirals.

Abstract
BACKGROUND/AIMS Interferon-based treatment is not appropriate for a large number of patients with chronic hepatitis C for various medical and social reasons. Newly developed directly acting antivirals (DAAs) have been used to treat chronic hepatitis C without severe adverse effects and have achieved a sustained viral response (SVR) rate of 80-90% with short treatment duration. We were interested to determine whether all patients who failed to respond to or were ineligible for interferon-based therapy could be treated with DAAs. METHODS Medical records of patients with positive serum anti-hepatitis C virus (HCV) or HCV RNA between January 2009 and December 2013 were reviewed. Demographic, clinical, and treatment data were collected for analysis. RESULTS A total of 876 patients were positive for both anti-HCV and HCV RNA. Of these, 244 patients were eligible for interferon, although this was associated with relapse in 39 (16%) of patients. In total, 130 patients stopped interferon therapy (67% adverse effects, 28% non-adherent, 4% malignancy, 1% alcohol abuse) and 502 patients were ineligible (66% medical contraindications, 25% non-adherent, 5% socioeconomic problems). Among 671 patients who were ineligible for or failed to respond to interferon therapy, more than 186 (27.7%) could not be treated with DAA due to financial, social, or cancer-related conditions. CONCLUSIONS Newly developed DAAs are a promising treatment for patients with chronic hepatitis C who are ineligible for or failed to respond to interferon-based therapy. Nevertheless, not all chronic hepatitis C patients can be treated with DAAs due to various reasons.

Abstract
PURPOSE OF REVIEW Current clinical practice guidelines recommend regular hepatocellular carcinoma (HCC) surveillance with biannual ultrasound with or without serum alpha-fetoprotein uniformly applied to all patients with cirrhosis. However, clinical implementation of this one-size-fits-all strategy has been challenging as evidenced by very low application rate below 20% due to various reasons, including suboptimal performance of the surveillance modalities. RECENT FINDINGS Newly emerging imaging techniques such as abbreviated MRI (AMRI) and molecular HCC risk biomarkers have increasingly become available for clinical evaluation and implementation. These technologies may have a potential to reshape HCC surveillance by enabling tailored strategies. This would involve performing optimized surveillance tests according to individual HCC risk, and allocating limited medical resources for HCC surveillance based on cost-effectiveness. SUMMARY Tailored HCC surveillance could lead to achievement of precision HCC care and substantial improvement of the current dismal patient prognosis.

Abstract
Treatment of hepatitis C virus (HCV) with newer directly acting antivirals (DAAs) and lead to sustained viral response (SVR) in majority of patients and SVR has been documented to be associated with reversal of liver cirrhosis. The improved SVR rates and safety profiles of DAAs have led to the treatment of patients with decompensated cirrhosis awaiting liver transplantation (LT). Several clinical trials of DAAs in decompensated HCV patients have recently demonstrated SVR rates above 80%, which have been associated with significant improvements, in the Child-Pugh-Turcotte scores/or model for end-stage liver disease scores in a proportion of patients. Moreover, it has been shown that HCV RNA becomes negative after 2-4 weeks of treatment, and those who are transplanted after becoming HCV RNA negative will be have very low the risk of HCV recurrence after transplantation. Some of the patients may have reached the "point of no return" and may proceed to worsening of decomposition over time. To avoid the risk of worsening, there is an additional option of treating these patients after LT should they develop recurrent HCV infection. Currently there are no guidelines as to select patients who would benefit from treatment prior to LT as opposed to those who will be better off being treated after the transplant surgery. The article discusses a possible approach for such selection.

Abstract
Primary liver cancer is the second leading cause of cancer-related death worldwide and therefore a major public health challenge. We review hypotheses of the cell of origin of liver tumorigenesis and clarify the classes of liver cancer based on molecular features and how they affect patient prognosis. Primary liver cancer comprises hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (iCCA), and other rare tumors, notably fibrolamellar carcinoma and hepatoblastoma. The molecular and clinical features of HCC versus iCCA are distinct, but these conditions have overlapping risk factors and pathways of oncogenesis. A better understanding of the cell types originating liver cancer can aid in exploring molecular mechanisms of carcinogenesis and therapeutic options. Molecular studies have identified adult hepatocytes as the cell of origin. These cells have been proposed to transform directly into HCC cells (via a sequence of genetic alterations), to dedifferentiate into hepatocyte precursor cells (which then become HCC cells that express progenitor cell markers), or to transdifferentiate into biliary-like cells (which give rise to iCCA). Alternatively, progenitor cells also give rise to HCCs and iCCAs with markers of progenitor cells. Advances in genome profiling and next-generation sequencing have led to the classification of HCCs based on molecular features and assigned them to categories such as proliferation-progenitor, proliferation-transforming growth factor β, and Wnt-catenin β1. iCCAs have been assigned to categories of proliferation and inflammation. Overall, proliferation subclasses are associated with a more aggressive phenotype and poor outcome of patients, although more specific signatures have refined our prognostic abilities. Analyses of genetic alterations have identified those that might be targeted therapeutically, such as fusions in the FGFR2 gene and mutations in genes encoding isocitrate dehydrogenases (in approximately 60% of iCCAs) or amplifications at 11q13 and 6p21 (in approximately 15% of HCCs). Further studies of these alterations are needed before they can be used as biomarkers in clinical decision making.

Abstract
BACKGROUND & AIMS Anti-hepatitis C virus (HCV) therapy by interferon (IFN)-free regimen with oral direct-acting antiviral drugs are tolerable in aged patients, with fewer adverse effects than IFN-based therapies. We investigated the efficacy and tolerability of an IFN-free anti-HCV therapy in extremely aged patients, as well as the survival benefit of sustained virologic response (SVR). METHODS Following IFN-free therapy with daclatasvir and asunaprevir, tolerability and SVR rate were compared between 115 HCV genotype 1-infected patients aged 80years or older, 151 patients in their 70s (⩾70 and <80years), and 115 patients under the age of 70. One-year mortality and morbidity in patients aged ⩾80years were compared between SVR patients and propensity score-matched patients with persistent HCV infection. RESULTS The SVR rate was 96.5% in patients ⩾80years, comparable to that in patients aged ⩾70 and <80years (95.4%) and patients aged <70years (93.9%). There were no differences in treatment discontinuation rate (2.6%, 1.3%, and 0.9%, respectively). One-year mortality was significantly lower in SVR patients (2.7%) than in patients with persistent HCV infection (15.3%, p=0.0016). Whereas 1-year mortality due to liver-related diseases was 8.1% in patients with persistent HCV infection who were aged ⩾80years, no SVR patients died from liver diseases within 1-year after the end of therapy. CONCLUSIONS IFN-free therapy for HCV infection was associated with high tolerability and antiviral efficacy, even in patients aged ⩾80years. In addition, there seemed to be a survival benefit from the eradication of HCV in this population. LAY SUMMARY IFN-free therapy with oral direct-acting antiviral drugs (daclatasvir and asunaprevir) for HCV infection showed similar tolerability and antiviral efficacy in patients aged ⩾80years as in younger patients (patients aged ⩾70 and <80years and patients aged <70years), with an SVR rate over 90% and no severe adverse effects. There was a survival benefit from the eradication of HCV even in patients aged ⩾80years.

Current therapy for chronic hepatitis C: The role of direct-acting antivirals. Antiviral Res 2017; 142:83-122. [PMID: 28238877 PMCID: PMC7172984 DOI: 10.1016/j.antiviral.2017.02.014] [Citation(s) in RCA: 120] [Impact Index Per Article: 17.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2016] [Revised: 02/07/2017] [Accepted: 02/22/2017] [Indexed: 12/12/2022]
Abstract
One of the most exciting developments in antiviral research has been the discovery of the direct-acting antivirals (DAAs) that effectively cure chronic hepatitis C virus (HCV) infections. Based on more than 100 clinical trials and real-world studies, we provide a comprehensive overview of FDA-approved therapies and newly discovered anti-HCV agents with a special focus on drug efficacy, mechanisms of action, and safety. We show that HCV drug development has advanced in multiple aspects: (i) interferon-based regimens were replaced by interferon-free regimens; (ii) genotype-specific drugs evolved to drugs for all HCV genotypes; (iii) therapies based upon multiple pills per day were simplified to a single pill per day; (iv) drug potency increased from moderate (∼60%) to high (>90%) levels of sustained virologic responses; (v) treatment durations were shortened from 48 to 12 or 8 weeks; and (vi) therapies could be administered orally regardless of prior treatment history and cirrhotic status. However, despite these remarkable achievements made in HCV drug discovery, challenges remain in the management of difficult-to-treat patients. HCV genotype-specific drugs evolve to pan-genotypic drugs. Drug potency increases from moderate (∼60%) to high (>90%) levels of sustained virologic response. Treatment durations are shortened from a 48-week to 12-week or 8-week period. HCV therapies based upon multiple pills per day are simplified to a single pill per day. HCV therapies are administered orally regardless of prior treatment history and cirrhotic status.

Abstract
Chronic HCV infection is a global health problem that affects >184 million people worldwide. HCV is associated with several hepatic and extrahepatic disorders, including several malignancies. The burden of HCV-related disorders is influenced by the number of new and existing cases, number of existing cases and the natural history of the infection. The natural history of HCV is affected by several demographic, virological, clinical and lifestyle factors. Major variations exist in the burden of HCV among different populations and geographical regions, as well as over time. With the advent of new and efficacious antiviral treatments, it is important to learn the determinants of HCV burden to design appropriate strategies for detection, prognostication and treatment. Furthermore, with the expected growth of patients cured of HCV, it is essential to learn about the possible change in natural history and burden of disease in these patients. In this Review, we will discuss the global epidemiology and burden of HCV and its complications, as well as the natural history and clinical course of chronic and cured HCV infection.

Abstract
Between 80 and 115 million people worldwide are chronically infected with hepatitis C virus, with 60%-90% of these being undiagnosed. Untreated chronic hepatitis C (CHC) is associated with progressive liver disease, cirrhosis, hepatocellular carcinoma and liver-related mortality. A number of extrahepatic manifestations are also reported in CHC patients, further adding to the burden of the disease. CHC also impacts patients in terms of lower health-related quality of life, higher levels of fatigue and reduced productivity. Furthermore, the later stages of disease are costly for both healthcare systems and society. Pegylated-interferon (PEG-IFN)+ribavirin (RBV), for many years the mainstay of treatment, leads to sustained virological response (SVR) in 40%-70% of patients. However, a substantial number of patients are ineligible for treatment, and many patients fail to achieve SVR with this regimen. Furthermore, PEG-IFN+RBV leads to impairment of patient-reported outcomes during treatment, and most patients suffer from adverse events, associated with poor adherence, treatment discontinuation and treatment failure. The approval of second-generation direct-acting antivirals (DAAs) has revolutionized the treatment of CHC patients. All-oral, PEG-IFN and RBV-free regimens have higher efficacy rates, shorter treatment durations, fewer adverse events, higher adherence rates and improvement in PROs from as early as Week 4, compared to PEG-IFN+RBV regimens. The aim of this article is to review the evidence for HCV infection as a systemic disease, summarizing the impact of hepatitis C and its treatments on clinical, patient and economic outcomes, with a focus on data from Asia and Japan specifically.

Favorable Outcomes of Chinese HCV-Related Cirrhotic Patients with Sustained Virological Response after Pegylated Interferon Plus Ribavirin Treatment. BIOMED RESEARCH INTERNATIONAL 2017; 2017:8061091.

Abstract
Few studies have conducted follow-up investigations of the clinical course in HCV-related cirrhotic patients who achieved a sustained virological response (SVR) with pegylated interferon plus ribavirin treatment (PegIFN + RBV). We investigated the clinical course and laboratory data in a prospective cohort study enrolling HCV-related cirrhotic patients who received PegIFN + RBV between August 2008 and July 2013 in China. Complete blood counts, liver function tests, and HCV-RNA were serially examined. Liver-related complications were recorded. To detect hepatocellular carcinoma (HCC), alpha-fetoprotein assays, and ultrasound scans were repeated at 6-month intervals. Twenty-five patients were enrolled, including 8 patients with decompensation events before treatment. Eighteen patients achieved SVR with a mean follow-up period of 25.78 months. During the follow-up period, only one patient exhibited HCV-RNA positivity and no decompensation events were detected, but 4 patients developed HCC after SVR. APRI decreased more in patients with SVR than in patients with non-SVR (median, -1.33 versus 0.86, P < 0.001). The albumin levels and platelet counts significantly increased during the follow-up period after SVR (44.27 ± 4.09 versus 42.63 ± 4.37, P = 0.037 and 173.89 ± 87.36 versus 160.11 ± 77.97, P = 0.047). These data indicated that HCV-related cirrhotic patients with SVR after PegIFN + RBV may have a favorable clinical course and improvements in laboratory data. Moreover, HCC should be monitored.

Abstract
INTRODUCTION Currently, hepatitis C virus (HCV) infection remains the most common indication for liver transplant in the United States (US) with almost universal HCV recurrence in the post-liver transplant setting. Previous interferon (IFN)-related efficacy and tolerability concerns about worsening liver function have limited treatment options for many patients with HCV-associated decompensated liver disease and post-liver transplant recipients. However, the last decade has seen a seen a radical shift in the management of HCV with multiple direct-acting antiviral (DAA) treatments that provide more effective, all-oral, IFN-free alternatives. Areas covered: This review will serve to highlight the various pharmacotherapies available to clinicians for patients with HCV recurrence post-liver transplant. A brief history of prior regimens is provided with evidence for newer treatments presented. Also detailed are updated guidelines from societal organizations. Finally, timing of HCV treatment is discussed as the decision to treat patients in a pre or post-liver transplant setting remains challenging. Expert opinion: While there are many potential available therapies for HCV recurrence in the post-liver transplant setting, daclatasvir/sofosbuvir and ledipasvir/sofosbuvir have been the most extensively studied. Newer, pangenotypic generation drugs require more evidence before routine utilization in post-liver transplant recipients.

Abstract
Direct antiviral agents mark a major progress for the treatment of chronic hepatitis C virus infection. The rate of cure is higher than 90% in most populations and the safety profile is good. However, like any treatment, there are potential unexpected adverse events. Several reports have indicated that antiviral therapy may be associated with the reactivation of hepatitis B virus or the emergence of herpes virus in a time-related manner. Recently, several studies have described a potential unexpected incidence of hepatocellular carcinoma in treated patients, both in those without a prior history of cancer and those who have been successfully treated and were disease-free for different periods of time. Furthermore, the emergence of cancer is also characterized by a more aggressive and faster progression to advanced stages, making treatment impossible. Thus, a careful risk-benefit analysis must be made when considering antiviral treatment with the new agents in patients with hepatitis C virus.

Abstract
In this new era of highly effective oral antiviral drugs for chronic hepatitis C virus (HCV), indications for antiviral treatment may be extendable. This study undertaken to identify suitable candidates for peg-interferon plus ribavirin (PEG-IFN/RBV) treatment by evaluating hepatocellular carcinoma (HCC) risk in patients with chronic HCV treated or not with PEG-IFN/RBV.This large-scale retrospective study was conducted on 1176 patients with chronic HCV without a history of HCC (treatment group [n = 489] and no-treatment group [n = 687]). In the treatment group, patients treated with PEG-IFN/RBV were dichotomized based on the achievement of sustained virologic response (SVR) into SVR (+) and SVR (-) groups.Median follow-up for all study subjects was 31 months (range 6-144 months). Three-year cumulative HCC development rates in the SVR (+) (1.1%) and SVR (-) (8.6%) subgroups were significantly lower than in the no-treatment group (13.5%) (P < 0.01 and P < 0.01, respectively). In all study subjects, presence of cirrhosis (hazard ratio [HR], 9.92, P < 0.01), age (HR 1.03, P < 0.01), SVR (-) (HR 7.02, P < 0.01), and no-treatment (HR 6.76, P < 0.01) were found to be independent risk factors of HCC development. In the treatment group, age, the presence of cirrhosis, and SVR (-) were predictors of HCC development. In the no-treatment group, age, male, and the presence of cirrhosis were independent predictors for HCC development.HCC risk increased in patients with chronic HCV with older age, cirrhosis, SVR (-) after PEG-IFN/RBV treatment, and no PEG-IFN/RBV treatment. Active antiviral therapy based on highly effective oral drugs needs to be considered in these patients.

Abstract
During the past two decades, several studies showed reduced rates of hepatocellular carcinoma recurrence in patients with HCV-related cirrhosis after interferon-based antiviral therapies respect to untreated controls, even without reaching viral clearance. The recent development of new all-oral regimens with direct-acting antivirals has radically improved the therapeutic management of hepatitis C. Nevertheless, paradoxical, or at least unexpected, high rates of both occurrence and recurrence of hepatocellular carcinoma after a treatment with direct-acting antivirals, have been reported in the recent literature. These findings generated a strong rebound in the hepatology community and are at present still controversial. We sought to compare the hepatocellular carcinoma recurrence-free survival of a historical cohort treated with pegylated interferon/ribavirin and an untreated cohort with a cohort treated with direct-acting antivirals.
