Hepatitis B virus (HBV) genomic mutations A1762T, G1764A and AG1762/1764TA cause production of HBV X protein (HBx) mutants, namely K130M, V131I and KV130/131MI. These mutations are important biomarkers for the development of cirrhosis and hepatocellular carcinoma (HCC) in chronic HBV patients. The present study comparatively analyzes the impact of intracellular expression of HBx mutants on HCC cell line Huh7. It was found that expression of KV130/131MI induced: cell proliferation; altered expression of cell cycle regulatory genes in favor of cell proliferation; intracellular reactive oxygen species (ROS) production and mitochondrial depolarization...

Adjuvant pegylated interferon plus ribavirin treatment (PegIFN/RBV) reduces recurrence and prolongs survival in early stage hepatocellular carcinoma (HCC) patients with chronic hepatitis C (CHC) infection receiving resection or ablation. However, the impact of antiviral therapy in intermediate and advanced stage of CHC-HCC patients is uncertain. This study aimed to investigate the impact PegIFN/RBV treatment on recurrence free interval and survival in HCC patients receiving transarterial chemoembolization (TACE) METHODS: From 2010 to 2013, 274 CHC patients from a 1073-patients based cohort composed of freshly diagnosed HCC and receiving TACE treatment the Chang Gung Memorial Hospital, Linkou Medical Center were recruited...

Hepatitis C Virus (HCV) chronic infection can be associated with extrahepatic manifestations such as mixed cryoglobulinemia and lymphoproliferative disorders that are endowed with increased rates of morbidity and all-cause mortality. In this study we used flow cytometry to evaluate the effect of Interferon-free antiviral treatment on peripheral blood lymphocytes in HCV patients with or without associated lymphoproliferative disorders. Flow cytometry analysis of peripheral blood lymphocytes were performed at baseline and at the end of treatment...

Intravenous drug use and sexual practices account for 60% of hepatitis C (HCV) and B (HBV) infection. Disclosing these activities can be embarrassing, reduce risk reporting, blood testing and diagnosis. In diagnosed patients, linkage to care remains a challenge. Audio-computer assisted survey interview (Audio-CASI) was used to guide HCV and HBV infection testing in urban clinics. Risk reporting, blood-testing, and serology results were compared to historical controls. A Patient Navigator (PN) followed up blood test results and provided patients with positive serology linkage to care...

First, we would like to thank Dr. Gade for his interest in our study. Obviously Dr. Gade wonders if our findings in HCV patients are an artifact due to systematic bias based on a neglect of the study subjects' education. In his opinion "patients with HCV have almost invariably been more poorly educated than comparison groups". We can assure him that his statement does not fit in respect to our study group as most of the patients were infected via blood transfusion or application of blood products. HCV infection is not inevitably associated with poor education (see table 1)...

The clinical characteristics of patients triply infected with HIV, HBV and HCV are notable. From January 2005 to June 2014, a total of 115 cART-naive HIV/HBV/HCV infected individuals were studied and 91 of them were followed-up consecutively after cART with 3TC. After cART with 3TC, the HBV-DNA positive rate decreased from 37.4% (43/115) to 9.9% (9/91) (P<0.001), whereas the HCV-RNA positive rate increased from 53.9% (62/115) to 70.3% (64/91) (P=0.016), and HCV-RNA level increased from 3.52 log10 copies/ml to 4...

Inadequate response to injecting drug use (IDU) is a significant problem the world over. Low levels of funding, political inaction, poor levels of health service coverage, high prevalence and incidence of IDU-related blood-borne viruses (BBVs), and ongoing stigmatisation/marginalisation affect people who inject drugs (PWID) regardless of the income status of the country they reside in. These barriers and system failings are, however, exacerbated in low and middle income countries (LMICs), meaning that the potential consequences of inaction are more pressing...

Dirks et al.(1) just published a study of 159 patients infected with hepatitis C virus. They are to be commended for excluding patients with advanced fibrosis or liver cirrhosis, HIV co-infection, and present drug addiction, which have confounded interpretation in many earlier studies of HCV. The four patient groups differed significantly from controls in most cognitive domains studied. However, for the evaluation of these cognitive test results, a crucial piece of information is missing in the article: education...

BACKGROUND: Hepatitis B virus (HBV)-reactivation has been reported during anti-hepatitis C treatment in patients with hepatitis C virus (HCV) and HBV co-infection. We aimed to evaluate the frequency and risk factors of HBV-reactivation during anti-HCV therapy and compared those between interferon (IFN)-free direct-acting antiviral (DAA)-therapies and IFN-based therapies. METHODS: 322 patients with HCV infection receiving anti-HCV therapy were retrospectively screened...

BACKGROUND AND AIMS: Combining peginterferon alfa-2a (pegIFN) with a nucleotide analogue can result in higher rates of HBsAg loss than either therapy given alone. Here we investigated the durability of the response to combination therapy in chronic hepatitis B (CHB) patients after 5 years of follow-up. METHODS: In the initial study, 92 CHB patients (44 HBeAg positive, 48 HBeAg negative) with HBV DNA > 100,000 c/mL (~20,000 IU/mL) and active hepatitis were treated for 48 weeks with pegIFN 180 μg/week and 10 mg adefovir dipivoxil daily...

We aimed to determine whether the HCV viral load after four weeks of treatment (W4VL) with direct-acting antiviral agents (DAAs) predicts sustained virologic response (SVR) in a real-world clinical setting. We identified 21,095 patients who initiated DAA-based antiviral treatment in the national Veterans Affairs (VA) healthcare system from 01/01/2014 to 06/30/2015. Week 4 viral load was categorized as undetectable, detectable below quantification, detectable above quantification with viral load ≤42 IU/mL and detectable above quantification with viral load > 42 IU/mL...

Community-based real-world outcomes on effectiveness of antiviral therapies for chronic hepatitis B virus (CHB) in Asians are limited. Whether hepatitis B surface antigen (HBsAg) loss correlates with undetectable virus and alanine aminotransferase (ALT) normalization on treatment or what predicts risk of seroreversion or detectable virus after stopping therapy is unclear. We aim to evaluate rates and predictors of HBsAg loss, seroconversion, ALT normalization and undetectable HBV DNA, including HBsAg seroreversion or re-emergence of HBV DNA among Asian CHB patients...

Hepatitis B virus (HBV) infection in the US is the most common among Asians followed by non-Hispanic blacks. However, there have been few studies that describe HBV infection and immunity by racial group. Our study aims to assess racial/ethnic disparities in the prevalence and awareness of HBV infection and immunity using nationally representative data. In the National Health and Nutrition Examination Survey 2011-2014, 14,722 persons had HBV serology testing. We estimated the prevalence of HBV infection, past exposure, and immunity by selected characteristics and calculated adjusted odds ratios using survey-weighted generalized logistic regression...

The advent of shorter duration, highly effective and well tolerated interferon-free therapy now provides an opportunity for virtually all HCV infected individuals to be cured. However, there continues to be a need to simplify and shorten treatment duration. Shortening therapy to 8 weeks with sofosbuvir and ledipasvir can be considered in treatment patients with HCV genotype 1 infection and low baseline viral load. A number of other 8 week dual and triple therapy direct acting antiviral (DAA) regimens are in advanced clinical development...

Renal safety is a major concern during long-term antiviral treatment for chronic hepatitis B (CHB). This study aimed to investigate the prevalence of chronic kidney disease (CKD) in patients with CHB that had been treated with antiviral therapy. This was a single center, cross-sectional study in a real-life cohort in which all patients received antiviral treatment. Serum creatinine-based equations from the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) were used to estimate the glomerular filtration rate (GFR)...

Antiviral drug resistance HBV variants (HBV-DR) occur spontaneously in chronic hepatitis B (CHB) patients and after exposure to nucleos(t)ide analogues (NUCs). We determined the prevalence of HBV-DR variants among participants of the Hepatitis B Research Network (HBRN) Cohort Study conducted at 21 sites in the United States (US) and Canada. Samples obtained from 1342 CHB participants aged ≥18 years, and who were currently not receiving NUCs, were tested for HBV-DR variants by Sanger sequencing. In addition, next generation sequencing (NGS) was used to characterize HBV-DR variants from 66 participants with and 66 participants with no prior NUC exposure matched for HBV genotype and HBV DNA level...

Hepatitis E virus (HEV) infection can be vertically transmitted but the factors that transmit the disease to fetuses are still unclear. We studied a total of 144 pregnant women with HEV infection. Cord blood and newborn samples were taken for analysis. Nutritional factors were evaluated on the basis of anthropometric parameters and biochemical factors and quantification of HEV viral load was carried out by Real Time PCR. Sequencing of HEV positive samples was performed. Approximately 14.63% (6/41) acute liver failure (ALF) pregnant patients died before delivery...

BACKGROUND & AIMS: An abundance of non-invasive scores have been associated with fibrosis and hepatocellular carcinoma (HCC) development. We aimed to compare the prognostic ability of these scores in relation to liver histology in chronic hepatitis B (CHB) patients. METHODS: Liver biopsies from treatment-naïve CHB patients at one tertiary care centre were scored by a single hepato-pathologist. Laboratory values at liver biopsy were used to calculate the PAGE-B, REACH-B, GAG-HCC, CU-HCC, and FIB-4 scores...

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]...

Recently, concerns were raised of high rates of HCC recurrence in patients treated with direct acting antivirals (DAA) for hepatitis C infection. We investigated the HCC occurrence and recurrence rates within six months after treatment with DAA with or without Pegylated Interferon (PEG-IFN) in real life. This is a retrospective, multicenter cohort trial, executed in 15 hospitals distributed across Belgium. Populations were matched based on fibrosis score (Metavir F3-F4). Patients with a Child-Pugh score ≥ B were excluded...
