BACKGROUND: A liver stiffness (LS) < 21 kPa has a high negative predictive value (NPV) to exclude the presence of esophageal varices (EV) at risk of bleeding in HIV/HCV-coinfected patients. Consequently, upper gastrointestinal endoscopy (UGE) for the screening of EV could be avoided in these patients. However, this strategy has not been widely accepted due to concerns about its safety. OBJECTIVE: To assess the ability of LS to predict the risk of portal hypertensive gastrointestinal bleeding (PHGB) in HIV/HCV-coinfected patients with compensated cirrhosis...

One third of all hepatitis C virus (HCV) cases in the United States are incarcerated in jails and prisons. Hepatitis C virus testing is primarily accomplished through a clinical laboratory, yet point-of-care (POC) testing is less invasive and results are available in 20 minutes compared with up to 3 weeks. The purpose of this article was to describe the findings of a collaborative project between the Colleges of Engineering and Nursing at the University of Massachusetts Amherst in executing a human factors study for HCV antibody testing and screening...

Hepatitis C virus (HCV) is a positive-sense single-stranded RNA virus with an estimated infection in ∼180 million people worldwide, and its chronic infection leads to development of cirrhosis and hepatocellular carcinoma. Although recent development of direct acting antiviral (DAA) compounds improved anti-HCV regimens, alternative therapeutic compounds are still demanded due to an expected emergence of escape mutants for those DAAs. In order to identify novel anti-HCV agents, we conducted chemical library screening for 2,086 compounds using HCV Rep-Feo reporter replicon in Huh7 hepatoma cells...

Hepatitis C virus (HCV) is frequently associated with various extrahepatic manifestations such as autoimmune features and immune complex deposit diseases. Oral lichen planus (OLP) is one of the representative extrahepatic manifestations of HCV infection. Direct-acting antivirals (DAA) are highly effective and safe for the eradication of HCV. However, there is a lack of information regarding the association between HCV-associated OLP and interferon (IFN)-free DAA therapy. Herein, we present the case of a 60-year-old female who was diagnosed with OLP during routine periodontal treatment by a dentist...

AIM: To investigate peg-interferon (peg-IFN) and ribavirin (RBV) therapy in Myanmar and to predict sustained virologic response (SVR). METHODS: This single-center, open-label, study was conducted in Myanmar between 2009 and 2014. A total of 288 patients infected with HCV genotypes 1, 2, 3 and 6 were treated with peg-IFN alpha-2a (180 μg/wk) or alpha-2b (50 to 100 μg as a weight-based dose) and RBV as a weight-based dose (15 mg/kg/d). Treatment duration was 48 wk for genotypes 1 and 6, 24 wk for genotype 2, and 24 or 48 wk for genotype 3 based on rapid virologic response (RVR)...

AIM: To develop a fast, low-cost diagnostic strategy to identify single point mutations in highly variable genomes such as hepatitis C virus (HCV). METHODS: In patients with HCV infection, resistance-associated amino acid substitutions within the viral quasispecies prior to therapy can confer decreased susceptibility to direct-acting antiviral agents and lead to treatment failure and virological relapse. One such naturally occurring mutation is the Q80K substitution in the HCV-NS3 protease gene, which confers resistance to PI inhibitors, particularly simeprevir...

Health-care workers (HCWs) are at risk of infections associated with accidental exposure to blood, including viral hepatitis B (HBV) and C (HCV). A survey using a questionnaire was conducted on 250 HCW in Bukavu, an eastern town of the Democratic Republic of Congo, to analyze their attitude and knowledge about these two viruses. A response rate of 86.8% (217/250) was obtained. The mean age of respondents was 39.6 ± 9.8 years, in majority from paramedical staff (66.4%) and with more than 5 years of professional experience (60...

Hepatitis C virus (HCV) mainly targets the liver but can also induce extrahepatic manifestations. The kidney may be impacted via an immune mediated mechanism or a cytopathic effect. HCV patients are clearly at a greater risk of chronic kidney disease (CKD) than uninfected patients are, and the presence of CKD increases mortality. Interferon-based therapies and ribavirin are difficult to manage and are poorly effective in end-stage renal disease and hemodialysis. These patients should be given priority treatment with new direct anti-viral agents (DAAs) while avoiding peginterferon and ribavirin...

Treatment of chronic hepatitis C virus (HCV) infection remains a priority in the veterans affairs (VA) health care system nationwide, as there is a high burden of liver disease due to HCV infection among US veterans. The combination of sofosbuvir and simeprevir was the first all-oral antiviral regimen used in clinical practice to treat veterans with HCV infection. In this study, we report a single-center experience showing both the feasibility and effectiveness of this all-oral combination to treat HCV genotype 1 infection...

The following report from the field focuses on the authors' collective efforts to operate an ad hoc safer injection facility (SIF) out of portapotties (portable toilets) in an area of the South Bronx that has consistently experienced some of the highest overdose morbidity and mortality rates in New York City over the past decade (New York City Department of Health and Mental Hygiene, 2011, 2015, 2016). Safer injection facilities (also known as supervised injection facilities, drug consumption rooms, etc.) operating outside the US provide a legal, hygienic, and supervised environment for individuals to use drugs in order to minimize the likelihood of fatal overdose and the spread of blood-borne infections while reducing public injection...

We evaluated the diagnostic usefulness of an HCV core antigen (HCV-Ag) assay in HCV-infected patients undergoing treatment with direct-acting antivirals. We analyzed 103 samples from 28 patients. Compared with RT-PCR, sensitivity was 96.2% and specificity was 100%. The correlation between techniques was excellent (Pearson coefficient: 0.871). HCV-Ag proved to be useful in patients with sustained viral response and in patients who experienced treatment failures.

Hepatitis C virus (HCV) enters into human hepatocytes via tetraspanin hCD81. HCV glycoprotein E2 recognizes the "head" subdomain of the large extracellular loop (LEL) of CD81 (hCD81LEL), but the precise mechanism of virus cell attachment and entry remains elusive. Here, by combining the structural analysis of a conspicuous number of crystallized CD81LEL molecules with molecular dynamics simulations, we show that the conformational plasticity of the hCD81LEL head subdomain is a molecular property of the receptor...

BACKGROUND: We examined discharges for infective endocarditis (IE) at an academic teaching hospital for over 10 years to evaluate if an increase in hospitalizations for IE and increase in hepatitis C virus (HCV) in patients with IE could predict a new epidemic of injection drug use (IDU). MATERIALS AND METHODS: Retrospective medical record review of discharged patients with the diagnosis of IE as defined by the modified Duke criteria. Student's t test, chi-squared test and Fisher's exact test were used to calculate P values...
