Christopher M Walker
Direct acting antivirals can cure chronic hepatitis C virus (HCV) infection but whether they will reduce global liver disease burden is uncertain. Most chronic infections are undiagnosed and transmission has increased in recent years. The first trial of a preventive vaccine is now underway in humans at risk for HCV infection. It will test the novel hypothesis that T cell-mediated immunity alone can prevent persistent HCV infection. Another vaccine that elicits neutralizing antibodies is at an advanced stage of development...

BACKGROUND: Diagnosis of hepatitis C virus (HCV) infection and treatment monitoring rely on detection/quantification of HCV RNA and real-time polymerase chain reaction (PCR) techniques are expected to equivalently quantify the different HCV genotypes. OBJECTIVE: The clinical performance of the VERIS HCV assay for HCV RNA quantification was compared to that of the Abbott RealTime HCV assay. STUDY DESIGN: Qualitative concordance and quantitative comparison were evaluated on a first panel of 286 clinical samples containing HCV genotypes 1-6...

Previous studies have shown inconsistent results with respect to hepatitis B (HBV), hepatitis C (HCV) and pregnancy outcome. The aim of this study was to investigate pregnancy outcome in women with HBV or HCV. In a nationwide cohort of births between 2001 and 2011 we investigated the risks of adverse pregnancy outcomes in 2990 births to women with HBV and 2056 births to women with HCV using data from Swedish healthcare registries. Births to women without HBV (n = 1090 979), and births without HCV (n = 1091 913) served as population controls...

Microorganism resistance is an important challenge in modern medicine due to the global uncontrolled use of antibiotics. Natural and synthetic antimicrobial peptides (AMPs) symbolize a new family of antibiotics, which have stimulated research and clinical interest as new therapeutic options for infections. They represent one of the most promising antimicrobial substances, due to their broad spectrum of biological activity, against bacteria, fungi, protozoa, viruses, yeast and even tumour cells. Besides, being antimicrobial, AMPs have been shown to bind and neutralize bacterial endotoxins, as well as possess immunomodulatory, anti-inflammatory, wound-healing, angiogenic and antitumour properties...

BACKGROUND & AIMS: The diagnostic accuracy of a novel serological panel (BioFibroScore®) to predict hepatic fibrosis in patients with chronic hepatitis C virus (HCV) infection is unknown. METHODS: Three markers of BioFibroScore®, including urokinase plasminogen activator (uPA), matrix metalloproteinase-9 (MMP-9), and beta-2 microglobulin (β2M), were retrospectively evaluated in 635 HCV-infected patients who received percutaneous liver biopsy and FibroScan®. The formula of BioFibroScore® to predict the severity of hepatic fibrosis was developed by Adaboost algorithm...

Hijacking of cellular biosynthetic pathways by human enveloped viruses is a shared molecular event essential for the viral lifecycle. In this study, the accumulating evidence of the importance of human glyceraldehyde-3-phosphate dehydrogenase (GAPDH) in the host secretory pathway led us to hypothesize that this moonlighting enzyme could play a key role in the lifecycle steps of two important Flaviviridae members, hepatitis C virus (HCV) and dengue virus (DENV). We used short interfering RNA (siRNA)-mediated knockdown of human GAPDH in Huh-7...

Hepatitis C virus (HCV) is a major cause of death from infectious disease and is still the leading indication for liver transplantation in the United States and other Western countries. All-oral, direct-acting antiviral (DAA) therapies have revolutionized the field, with HCV cure rates of more than 90% among treated patients. The safety and tolerability of these DAA agents have expanded the feasibility of HCV treatment even in the challenging pre- and post-liver transplant settings. However, the unique properties of DAA agents and the host profiles in these settings can limit the generalizability of HCV regimens, and prolongation of treatment duration or addition of ribavirin may be required in certain scenarios to optimize treatment outcomes...

Primary Biliary Cholangitis, previously known as Primary Biliary Cirrhosis, is a rare disease, which mainly affects women in their fifth to seventh decades of life. It is a chronic autoimmune disease characterized by a progressive damage of interlobular bile ducts leading to ductopenia, chronic cholestasis and bile acids retention. Even if the disease usually presents a long asymptomatic phase and a slow progression, in many patients it may progress faster toward cirrhosis and its complications. The 10year mortality is greater than in diseases such as human immunodeficiency virus/Hepatitis C Virus coinfection and breast cancer...

BACKGROUND: Hepatitis C virus (HCV) core protein and nonstructural protein 4B (NS4B) are potentially oncogenic. Aberrant activation of the Wnt/β-catenin signaling pathway is closely associated with hepatocarcinogenesis. We investigated the effects of HCV type 1b core protein and NS4B on Wnt/β-catenin signaling in various liver cells, and explored the molecular mechanism underlying HCV-related hepatocarcinogenesis. RESULTS: Compared with the empty vector control, HCV core protein and NS4B demonstrated the following characteristics in the Huh7 cells: significantly enhanced β-catenin/Tcf-dependent transcriptional activity (F = 40...

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...

The United States Preventive Services Task Force (USPSTF) recommended one-time HCV testing for all patients in the 1945-1965 birth cohort, given the high hepatitis C virus (HCV) prevalence in this group [1]. In response, various interventions differing in complexity and cost have been developed. Goel et al, evaluated a multifaceted intervention sequentially implemented and report poor response to the electronic health record (EHR) alert and a very successful HCV screening, increased by 137%, after adding other tools including physician education, data feedback, and patient navigation [2]...

Interferon-stimulated gene 15 (ISG15) is a ubiquitin-like protein induced by type I interferon. Although several groups have reported ISGylation of the HCV NS5A protein, it is still unclear whether ISGylation of NS5A has anti-viral or pro-viral effects in HCV infection. In the present study, we examined the role of ISGylation-independent, unconjugated ISG15 in HCV infection. Immunoprecipitation analyses revealed that ISG15 specifically interacted with NS5A domain I. The ISG15 mutants lacking a C-terminal glycine residue essential for ISGylation still interacted with NS5A protein...

Few data are available concerning the roles of polymorphisms of inosine triphosphatase (ITPA) gene and ribavirin (RBV) transporter genes in the prediction of RBV-induced anemia among Egyptians with chronic hepatitis C (CHC). Genotyping of 3 ITPA gene variants and 2 variants of RBV transporter genes has been performed in 123 patients under pegylated interferon-α/ribavirin treatment. The baseline hemoglobin and ITPA rs1127354 CA/AA have been found as predictors of anemia at 4, 8 and 12 weeks of RBV therapy. In addition, ITPA rs7270101 AC/CC and age predicted anemia after 12 weeks of therapy...

Liver fibrosis is common, particularly in human immunodeficiency virus infected (HIV+) people. HIV+ people have excess congestive heart failure (CHF) risk compared to uninfected people. It remains unknown if stage of liver fibrosis influences the CHF risk or if HIV or hepatitis C virus (HCV) infection modifies this association. Our objectives were to assess whether: 1) stage of liver fibrosis is independently associated with incident CHF; 2) the association between stage of liver fibrosis and incident CHF is modified by HIV/HCV status...

BACKGROUND & AIMS: Children with chronic hepatitis C virus (HCV) infection have limited treatment options. We evaluated the all-oral combination of sofosbuvir and ribavirin in adolescents aged 12-17 with HCV genotype 2 or 3. METHODS: Fifty-two patients received sofosbuvir 400mg once daily and weight-based ribavirin twice daily for 12 (genotype 2) or 24 (genotype 3) weeks. The pharmacokinetics of sofosbuvir and its metabolite GS-331007 were evaluated by intensive plasma sampling at day 7 in the first 10 patients enrolled, and by sparse sampling in all patients throughout treatment...

BACKGROUND: Hepatitis C virus (HCV) infection remains a significant problem in the United States, with people who inject drugs (PWID) disproportionately afflicted. Over the last decade rates of heroin use have more than doubled, with young persons (18-25 years) demonstrating the largest increase. METHODS: We conducted a cross-sectional study in New York City from 2005 to 2012 among young people who injected illicit drugs, and were age 18 to 35 or had injected drugs for ≤5 years, to examine potentially modifiable factors associated with HCV among young adults who began injecting during the era of syringe services...
