BACKGROUND&AIMS: Portal hypertension is a predictor of liver-related clinical events and mortality in patients with hepatitis C and cirrhosis. The effect of interferon-free hepatitis C treatment on portal pressure is unknown. METHODS: Fifty patients with Child-Pugh-Turcotte (CPT) A and B cirrhosis and portal hypertension (hepatic venous pressure gradient [HVPG] >6 mmHg) were randomized to receive 48 weeks of open-label sofosbuvir plus ribavirin at Day 1 or after a 24-week observation period...

With effective antiviral therapies, rates of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) and decompensated liver disease requiring liver transplantation (LT) are expected to decrease. We aim to evaluate overall trends in LT waitlist registrations, waitlist survival, and likelihood of receiving LT among chronic HBV patients in the U.S. Using the United Network for Organ Sharing database, we retrospectively evaluated adults (age >18) with chronic HBV (with and without HCC) listed for LT from 1992-1996 (Era 1) vs...

Chronic hepatitis C virus (HCV) infection has been associated with an increased risk for cardiovascular disease (CVD). The recommended Pooled Cohort Atherosclerotic Cardiovascular Disease (ASCVD) risk equation for estimation of 10-year CVD risk has not been validated in HCV-infected populations. We examined the performance of the ASCVD risk score in HCV-infected persons, using the national Electronically Retrieved Cohort of HCV Infected Veterans (ERCHIVES) to derive a cohort of HCV-infected and uninfected subjects without baseline ASCVD, hepatitis B, or HIV infection, and with low-density lipoprotein cholesterol level<190 mg/dL...

BACKGROUND: Treatment for chronic hepatitis C virus (HCV) infection has rapidly evolved into interferon-free directly acting antiviral regimens (DAA) that result in high sustained-virologic-response. DAAs primarily work by suppressing HCV replication and rely less on the immune system than interferon-based therapies. However it is unclear whether the immune system recovers with suppression of HCV replication and contributes to HCV clearance with DAA therapy. We previously demonstrated HCV clearance is associated with increased HCV-specific-immunity in CHCV-GT-1 infected patients during treatment with sofosbuvir (SOF)+ribavirin (RBV)...

In this study a representative group of Mongolian adults was tested for hepatitis B virus (HBV) and hepatitis C virus (HCV). Screening was conducted at 17 different locations on a randomly sampled group, representative of the Mongolian adult population. A total of 1158 adults, 500 (43.1%) men and 659 (56.9%) women were included. The prevalence estimates of HBV and HCV among the general Mongolian adult population were found to be 11.1%± 1% (SE) and 8.5% ± 0.7% or 207,418 and 160,228 cases, respectively. For HCV the majority of cases are concentrated in older age groups with a prevalence of 25...

Accurate staging of liver fibrosis is important for clinical decision making and personalized management. Liver fibrosis is influenced by patients' genomics, including IFNL3 genotype and microRNA expression. However, incorporating microRNAs into fibrosis prediction algorithms has not been investigated. We examined the potential of 8 selected serum microRNAs; miR-122, miR-126, miR-129, miR-199a, miR-155, miR-203a, miR-221, and miR-223 as non-invasive biomarkers to stage liver fibrosis in HCV-associated chronic liver disease (HCV-CLD)...

Killer immunoglobulin-like receptors (KIRs) regulate the activation of Natural Killer cells through their interaction with human leukocyte antigens (HLA). KIR and HLA loci are highly polymorphic and certain HLA-KIR combinations have been found to protect against viral infections. In this study we analyzed whether the KIR/HLA repertoire may influence the course of hepatitis B virus (HBV) infection. Fifty-seven subjects with chronic hepatitis B (CHB), 44 subjects with resolved HBV infection, and 60 healthy uninfected controls (HC) were genotyped for KIR and their HLA ligands...

Chronic hepatitis B infection (CHB) causes up to 1.0 million deaths annually. Currently, more than 90% of CHB patients worldwide are receiving indefinite nucleos(t)ide analogue (NA) therapy. New strategies for optimizing hepatitis B surface antigen (HBsAg) loss are required for NA-treated patients as the majority are unable to achieve HBsAg loss and may require lifelong therapy. In hepatitis B e antigen (HBeAg)-positive patients, switching from NAs to finite peginterferon (PegIFN) therapy can double HBeAg seroconversion rates...

Approximately 240 million people have chronic hepatitis B worldwide, with mother-to-child-transmission (MTCT) accounting for most cases. Therefore, Henan Province, China launched a public health program to prevent MTCT. To determine the efficacy of this health program, a survey was carried out in Huixian and Xinan counties, which are located in northern and western Henan. All infants born in these two counties between January 1, 2013 and March 31, 2014 to a mother positive for hepatitis B surface antigen (HBsAg), were surveyed; in total, there were 438 mother-infant pairs...

Hepatitis B surface antigen (HBsAg) reduction during nucleoside/nucleotide analog (NA) therapy is slow and an alternative strategy for patients receiving ongoing NA to facilitate HBsAg reduction is required. We investigated whether switching to pegylated interferon (PEG-IFN) after long-term NA administration enhances HBsAg reduction. Forty-nine patients who switched from long-term NA to 48 weeks of PEG-IFN alfa-2a were studied. The mean duration of previous NA was 48 months (sequential group). A total of 147 patients who continued NA and matched for baseline characteristics were analyzed for comparison (NA continuation group)...

We examined the relationship between hepatitis B surface and core-related antigens (HBsAg, HBcrAg) and hepatocellular carcinoma (HCC) development in patients with undetectable serum HBV DNA receiving nucleos(t)ide analogue (NA). Seventy-six HBV carriers with undetectable HBV DNA (<20 IU/mL) who subsequently developed HCC were compared with 152 matched controls. Clinical and laboratory parameters (including novel assays to measure linearized HBsAg [HQ-HBsAg] and HBcrAg) were analyzed. There were no significant differences in HBsAg/ HQ-HBsAg levels between the two groups...

Hepatitis E virus (HEV) infection has been associated with a wide range of extrahepatic manifestations, so this study was designed to examine the effect and role of HEV on structural and molecular changes in the testicular tissues of Mongolian gerbils experimentally infected with swine HEV. HEV RNA was first detected in testis at 14 day post inoculation and reached a peak between 28 to 42 days later with viral load between 3.12 logs g-¹ to 6.23 logs g-¹ by PCR assays. Microscopic changes showed vacuolation, sloughing of germ cells, formation of multinuclear giant cells, degeneration, necrosis of tubules and damaged blood-testis barrier was observed through transmission electron microscopy...

We investigated breakthrough infection and hepatitis B virus (HBV) genetic changes in immunized subjects after 25-year of a universal infant immunization. Specifically, serum HBV DNA, genotypes, surface antigen mutants and nucleoside analog-resistant (NAr) mutants were assessed in 2853 subjects (<25-years-old) surveyed in 2009, and these data were compared with the data from previous serosurveys. A comparison across different age-stratified groups using the 2009 data revealed a significant increase in the seropositive rate of anti-HBc (5...

Current treatment options for patients with chronic hepatitis B virus (HBV) infection are not curative as they are not effective in eliminating covalently closed circular DNA (cccDNA). cccDNA is a stable template for HBV transcription in the nucleus of hepatocytes and is thought to be one of the main factors responsible for HBV persistence. Recently, activation of the lymphotoxin beta receptor (LTβR) has been shown to trigger degradation of cccDNA through induction of cytidine deaminases of the APOBEC3 family in HBV cell culture model systems...
