Direct-acting antiviral agents (DAAs) represent the standard of care for patients with hepatitis C virus (HCV) infection. Combining DAAs with different mechanisms may allow for shorter treatment durations that are effective across multiple genotypes. The aim of the C-SWIFT study was to identify the minimum effective treatment duration across multiple genotypes. C-SWIFT was an open-label, single-center trial in treatment-naïve patients with chronic HCV genotype (GT)1 or 3 infection. All patients received elbasvir (EBR) 100 mg/grazoprevir (GZR) 50 mg with sofosbuvir (SOF) 400 mg for 4-12 weeks...

Between western European countries, the hepatitis C virus (HCV) endemic is highest in Italy. The main objective of this paper is to estimate the endemic diffusion of hepatitis C at the national level and by geographical area, with an extrapolation at the regional level and by uniform cohorts of subjects (by sex and year of birth). The secondary objective is a stratification by gravity of the estimated statistical figures to provide an overview of possible targets of the new anti-HCV treatments.PubMed and the Cochrane Library were searched for relevant Italian populations studies regarding HCV prevalence...

We assessed implementation of precision medicine within the Veterans Health Administration. We analyzed the use of interleukin-28B (IL28B) pharmacogenetic test, which predicts interferon-α treatment response in patients with hepatitis C. Patients with favorable CC genotype exhibit a two-fold higher response than patients with less favorable genotypes (CT and TT). Linking IL28B tests to Veterans Health Administration clinical data, we analyzed test use, concordance with guidelines, subsequent interferon-α treatment, and site variations...

Hepatitis C virus (HCV) is a globally prevalent pathogen and is a major cause of healthcare burden in India. HCV poses a significant problem in the state of Punjab, India owing to the higher prevalence of risk factors like unsafe medical practices (including unsafe injections and dental procedures) and intravenous drug use. The reported prevalence of HCV in this part of the country was 5.2% in 2012, while a recent study has shown the prevalence to be 3.2% in 2016. Similar to the other geographic belts in India, genotype 3 predominates in the state of Punjab...

In this study, we assessed the prevalence of overt and occult hepatitis B virus (HBV) infection among leukemia patients. Among 256 leukemia patients and 377 fracture patients (control group), we found that the hepatitis B surface-antigen-positive rate was greater in leukemia patients than in the controls (odds ratio, 2.08; p = 0.01). Moreover, the prevalence of occult HBV infection was higher in leukemia patients than in the controls (10.5 % vs. 2.9 %; odds ratio, 3.92; p < 0.001). The HBV genotype distribution differed significantly between the leukemia and chronic hepatitis B or control groups (p < 0...

BACKGROUND: Vulnerable populations are disproportionately affected by hepatitis C virus (HCV) infection and experience high rates of health disparity. There are no data on real-world experience with highly efficacious direct-acting anti-HCV treatment in this population. AIMS: We aimed to evaluate the real-world experience with sofosbuvir-based regimens among a vulnerable HCV-infected population. METHODS: HCV treatment response was assessed among 204 patients who completed 12-24 weeks of sofosbuvir-based regimens (in combination with pegylated interferon and ribavirin, simeprevir, ledipasvir, or daclatasvir) at the San Francisco safety-net healthcare system liver specialty clinic between January 2014 and December 2015...

:  Background. The protein encoded by PARK2 gene is a component of the ubiquitin-proteasome system that mediates targeting of proteins for the degradation pathway. Genetic variations at PARK2 gene were linked to various diseases including leprosy, typhoid and cancer. The present study investigated the association of single nucleotide polymorphisms (SNPs) in the PARK2 gene with the development of hepatitis C virus (HCV) infection and its progression to severe liver diseases. MATERIAL AND METHODS: A total of 800 subjects, including 400 normal healthy subjects and 400 HCV-infected patients, were analyzed in this study...

Hepatitis E virus (HEV) causes acute self-limiting hepatitis in most cases and chronic infection in rare circumstances. It is believed to be noncytopathic, so immunologically mediated events should play important roles in its pathogenesis and infection outcomes. The anti-HEV antibody response was clarified when the major antigenic determinants on the ORF2 polypeptide were determined, which are located in its C-terminal portion. This subregion also forms the conformational neutralization epitopes. Robust anti-HEV immunoglobulin M (IgM) and IgG responses usually develop 3-4 weeks after infection in experimentally infected nonhuman primates...

BACKGROUND:  Development of direct-acting antivirals in recent years has dramatically enhanced rates of viral eradication to >90% in patients with chronic hepatitis C virus (HCV) infection. To determine true treatment efficacy and to define the most appropriate retreatment, it is important to distinguish virologic relapse from reinfection where patients who achieve HCV eradication during treatment become infected with a new HCV strain posttreatment. METHODS:  Here, we investigated prevalence of late recurrent viremia (patients who achieved SVR12 but had detectable HCV RNA at follow up week 24) and used refined phylogenetic analysis of multiple HCV genes to distinguish virologic relapse from reinfection...
