Abstract
BACKGROUND Recent data have suggested that failure to achieve sustained virological response with direct-acting antiviral therapy is usually due to relapse and is primarily associated with the emergence of resistance-associated substitutions. The aim of this study was to investigate the prevalence and characterization of non-structural-5A resistance-associated substitutions in patients infected with HCV genotypes 1, 3 and 4 treated by direct-acting antiviral therapy, including anti-non-structural-5A, and to characterize the pre-existing resistance-associated substitutions in subjects treated with anti-non-structural-5A inhibitors. METHODS From January 2014 to March 2016, 2,995 patients infected with HCV genotypes 1, 3 and 4 were exposed to non-structural-5A inhibitors. Sequencing results at the time of virological failure were available for 61 patients; sequencing at baseline was available for 35 of these patients. RESULTS Among the 35 patients with sequencing results available at baseline, 15 had no resistance-associated substitution, 16 had only one resistance-associated substitution, and 4 had more than one resistance-associated substitution. Resistance-associated substitutions were harbored in 57% of the sequences in the non-structural-5A region. Among the 61 patients sequenced at virological failure, 50 (82%) patients presented at least one resistance-associated substitutions inducing a high level of resistance to non-structural-5A inhibitors (>10-fold resistance). CONCLUSIONS This pooled analysis suggests that non-structural-5A resistance-associated substitutions screening should be recommended when considering retreatment with a non-structural-5A inhibitor regimen in patients who have previously experienced failed non-structural-5A treatment.

International Liver Transplantation Society Asian Consensus on the Management of Hepatitis C Virus Infection in Resource Limited Setting-From Noncirrhotic to Decompensated Disease and After Liver Transplantation.

Abstract
BACKGROUND The population of Asia exceeds 4.4 billion people. Chronic hepatitis C virus (HCV) infection in Asia is characterized by specific distribution of genotypes, lack of access to specific therapeutic agents, relatively high cost of treatment, and lack of experienced healthcare providers. Clear consensus on the diagnosis, management, and monitoring of HCV infection specific to the Asian region is a major unmet need. The consensus guidelines documents that have been published to date by major medical societies presume access to an array of direct acting antiviral agents and diagnostic tests that are not broadly applicable to resource limited settings, including Asia. METHODS To address the lack of an Asia-specific set of HCV treatment guidelines, we assembled a panel of 15 HCV experts in the field of hepatology from India, Indonesia, Myanmar, Vietnam, Pakistan, Philippines, and Mongolia convened in April 2017 to review the updated literature and provide recommendations on the diagnosis and management of chronic HCV infection that reflects local conditions. RESULTS An evidence-based comprehensive compilation of the literature supported by the graded recommendations from the expert panel for the optimization of the diagnosis, pretreatment, on treatment, and posttreatment assessments, and management of chronic HCV infection has been presented in this article. CONCLUSIONS With the evolving treatment landscape and addition of several new direct-acting antiviral agents and combination regimens into the therapeutic armamentarium, the current article may serve as a guide to the clinicians in optimizing the diagnosis and treatment selection for the management of chronic HCV infection in resource-limited settings.

Changes in practice and perception of hepatitis C and liver transplantation: Results of a national survey. Transpl Infect Dis 2018; 20:e12982. [PMID: 30144258 DOI: 10.1111/tid.12982] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2018] [Revised: 06/14/2018] [Accepted: 08/12/2018] [Indexed: 12/18/2022]
Abstract
With new practice guidelines, it is important to understand how liver transplant (LT) centers have incorporated direct-acting antivirals (DAAs) into the management of hepatitis C virus-infected (HCV+) candidates and recipients. To explore how DAAs have affected LT centers' willingness to treat HCV+ candidates and recipients and to use HCV+ donors, we surveyed high volume US LT centers (11/2014-12/2015) regarding practices for HCV+ candidates, recipients, and donors, before vs after DAAs. We used the Scientific Registry of Transplant Recipients to compare centers' number of LTs, HCV+ recipients, and HCV+ donors in the years before (1/1/2012-12/31/2013) and after (1/1/2016-12/31/2017) survey administration. Of 80 centers contacted, 57 (71.3%) responded, representing 69.0% of the total volume of LTs in 2013. After DAAs, most centers increased treating candidates with low (≤15) model for end-stage liver disease (MELD) (85.2%), intermediate/high (>15) MELD (92.6%), and hepatocellular carcinoma (79.6%). There was consensus to treat low MELD candidates (90.8% "most of the time/always"), but less certainty for intermediate/high MELD candidates (48.2% "sometimes"). Universal post-LT HCV treatment increased (7.4% vs 57.4%). After DAAs, 42.6% were more willing to use HCV+ donors for HCV+ candidates, and 38.9% were willing to consider using HCV+ donors for HCV- candidates. Overall, with DAAs, centers were more willing to treat HCV+ candidates and recipients and to use HCV+ donors; recent recommendations may help to guide treatment decisions for intermediate/high MELD candidates.

Abstract
Chronic hepatitis C virus (HCV) infection remains a widespread public health concern and many people are infected with HCV. HCV is one of the leading indications for liver transplantation. Direct-acting antiviral agents (DAAs) against HCV have changed the course of chronic HCV infection, however, making it a curable disease. DAA treatment may be initiated before or after liver transplantation. In the present review, we present the available data on DAA treatment of HCV in liver transplant recipients.
