Objective: Less surveys on the economic burden of hepatitis B (HB)-related diseases have been conducted in China, so the socioeconomic harm caused by the diseases is not clear and the key parameters for economic evaluation of hepatitis B prevention and treatment are lacking. This study aimed to analyze the direct, indirect and intangible expenditures of hospitalized patients with HB-related diseases during hospitalization and during a year in different areas of China. Methods: The hospitals for infectious diseases and the large general hospitals in 12 areas in China were selected in the study...

WHO has developed and issued global hepatitis B elimination program. Continuing hepatitis B immunization and conducting community based antiviral treatment for chronic hepatitis B are the most important strategies for hepatitis B elimination. According to the estimation of related cost by WHO, the cost of antiviral therapy would be very high. Great achievement has been made in hepatitis B immunization in China, but the prevalence of chronic hepatitis B is high. Elimination of hepatitis B needs a large amount of public resource, posing serious challenge to public health policy making...

GOALS: To determine the impact of geography and patient characteristics on hepatitis C virus (HCV) genotype and subtype distribution in a large sample of patients under routine clinical care BACKGROUND:: HCV genotype impacts disease course and response to treatment. Although several studies have reported genotype distribution within specific US populations, there are no comprehensive descriptions in large, geographically diverse cohorts. STUDY: Using data from the Chronic Hepatitis Cohort Study, we present the distribution of HCV genotypes (GT) and subtypes (ST) among a racially diverse cohort of over 8000 HCV-infected patients from four large US health systems...

Adoptive transfer of T cells engineered to express a hepatitis B virus-specific (HBV-specific) T cell receptor (TCR) may supplement HBV-specific immune responses in chronic HBV patients and facilitate HBV control. However, the risk of triggering unrestrained proliferation of permanently engineered T cells raises safety concerns that have hampered testing of this approach in patients. The aim of the present study was to generate T cells that transiently express HBV-specific TCRs using mRNA electroporation and to assess their antiviral and pathogenetic activity in vitro and in HBV-infected human liver chimeric mice...

Multiple groups of patients have been recognized for having high rates of non-responders to the Hepatitis B vaccine including those with HIV, inflammatory bowel disease, and chronic kidney disease. These patients are at increased risk for infection due to both the nature of their underlying diseases and the immunosuppressive drugs they are commonly prescribed. Identification of groups with high non-response rates is essential in order to establish vaccination guidelines and prevent serious infections in already susceptible patients...

Chronic hepatitis B virus (HBV) infection within the Canadian Arctic is considered endemic (>2% prevalence). Within the Arctic region of Nunavut, a vaccination program targeted at newborn infants was initiated approximately 20years ago, along with interim grade school catch-up programs, with the result that individuals born after 1980 are presumed vaccinated. This study investigates the effectiveness of these programs and is the first seroepidemiological survey to determine HBV prevalence in Nunavut in the post-vaccination era...

BACKGROUND & AIMS: There is currently no virological cure for chronic hepatitis B but successful nucleos(t)ide analogue (NA) therapy can suppress hepatitis B virus (HBV) DNA replication and, in some cases, result in HBsAg loss. Stopping NA therapy often leads to viral relapse and therefore life-long therapy is usually required. This study investigated the potential to discontinue tenofovir disoproxil fumarate (TDF) therapy in HBeAg-negative patients. METHODS: Non-cirrhotic HBeAg-negative patients who had received TDF for ≥4 years, with suppressed HBV DNA for ≥3...

Chronic hepatitis B virus (HBV) infection remains a global problem. Several HBV (sub)genotypes exist with different biology and geographical preponderances. While the future aim of HBV treatment remains virus eradication, current strategies of treatment aim to suppress the virus and prevent the progression of liver disease. Current strategies also involve identification of patients for treatment - those at risk of progressive liver disease. Identification of HBV genotype, HBV mutants and other predictive factors allow for tailored treatments, and also risk-surveillance pathways such as for hepatocellular cancer screening...

Tissue resident memory T cells (TRM) have been identified in various tissues, however human liver TRM to date remain unidentified. TRM can be recognized by CD69 and/or CD103 expression and may play a role in the pathology of chronic hepatitis B (CHB) and hepatitis C virus infection (CHC). Liver and paired blood mononuclear cells from 17 patients (including 4 CHB and 6 CHC patients) were isolated and CD8+ T cells were comprehensively analysed by flowcytometry, immunohistochemistry and qPCR. The majority of intrahepatic CD8+ T cells expressed CD69, a marker used to identify TRM, of which a subset co-expressed CD103...

Complete removal of hepatitis B virus (HBV) DNA from nuclei is difficult by the current therapies. Recent reports have shown that a novel genome-editing tool using Cas9 with a single-guide RNA (sgRNA) system can cleave the HBV genome in vitro and in vivo. However, induction of a double-strand break (DSB) on the targeted genome by Cas9 risks undesirable off-target cleavage on the host genome. Nickase-Cas9 cleaves a single strand of DNA, and thereby two sgRNAs are required for inducing DSBs. To avoid Cas9-induced off-target mutagenesis, we examined the effects of the expressions of nickase-Cas9 and nuclease dead Cas9 (d-Cas9) with sgRNAs on HBV replication...

Despite its proven efficacy, the hepatitis B vaccine requires improvements in immune enhancement and durability, especially in the elderly. Levamisole, an immune modulator, has been tested as an adjuvant to hepatitis B vaccine in several studies in immune-compromised populations. However, we aimed to evaluate the effect of levamisole on the immune response to hepatitis B vaccine in healthy subjects. In this randomized clinical trial, healthy family members of chronic hepatitis B patients were given twenty-microgram intramuscular injections of hepatitis B vaccine at 0, 1, and 6 months and 50 miligrams of oral  levamisole twice a day for two weeks with every vaccination dose...

BACKGROUND AND AIM: Robust baseline predictors of interferon (IFN) response in HBeAg negative chronic hepatitis B (CHB) patients are not currently available. The recently described rs368234815 TT/ΔG dinucleotide and rs117648444 nonsynonymous P70S polymorphisms in IFN lambda 4 (IFNL4) gene, which are strongly associated with response to IFN in hepatitis C virus (HCV) infection, could be also useful in IFN treated CHB patients. Here we assessed whether IFNL4 rs368234815 and rs117648444 polymorphisms predict IFN induced HBsAg clearance in CHB patients...

To better understand the dynamics of early hepatitis C virus (HCV) infection, we determined how rapidly non-cirrhotic HCV-uninfected liver allografts clear HCV from the circulation of cirrhotic HCV-infected patients at the time of transplantation but before administration of immunosuppression. Specifically, we characterized serum HCV kinetics during the first 90 min of reperfusion for 19 chronically HCV-infected patients transplanted with an HCV-uninfected liver by measuring serum viral load immediately prior to reperfusion (t = 0) and then every 15 min for a total of 90 min (t = 90)...

In chronic hepatitis B virus (HBV)-infected patients, T helper 17 (Th17) cells are significantly elevated. Th17 cells initiate immune‑mediated pathogenesis and have a critical role in the process of HBV‑related liver cirrhosis (HBV‑LC). The mechanisms underlying this process are attributed to Th17‑secreted cytokines, which include interleukin (IL)‑17, IL‑21 and IL‑22; however, a systemic analysis regarding these mechanisms has yet to be conducted. Therefore, the present study aimed to investigate the role of Th17 cells in the pathogenesis of HBV‑LC...
