BACKGROUND Hepatitis B virus (HBV) infection significantly contributes to the onset of liver disease and hepatocellular carcinoma. Understanding the pathogenesis of HBV infection susceptibility could help us to control HBV infection effectively. OBJECTIVES This study investigated single nucleotide polymorphisms (SNPs) of the tripartite motif-containing 22 (TRIM22) gene associated with HBV inf...

Hepatitis B virus (HBV) infection is the major etiology of chronic liver disease worldwide and thus a global health problem, especially in Asia-Pacific region. The long-term outcomes of Asian HBV carriers vary widely; however, a significant proportion of them will finally develop end-stage liver disease. Over the past decade, several host and HBV factors predictive of clinical outcomes in Asian...

Remarkable progress has been made in our understanding of the natural history of chronic hepatitis B virus (HBV) infection in the past 25 years. Availability of sensitive HBV DNA assays and application of sophisticated immunological techniques led to the recognition that HBV replication persists throughout the course of chronic HBV infection, and host immune response plays a pivotal role in HBV...

Chronic Hepatitis B Virus (HBV) infection is linked to hepatocellular carcinoma (HCC) pathogenesis. Despite the availability of a HBV vaccine, current treatments for HCC are inadequate. Globally, 257 million people are chronic HBV carriers, and children born from HBV-infected mothers become chronic carriers, destined to develop liver cancer. Thus, new therapeutic approaches are needed to target...

Under most circumstances, HBV is not cytopathic and it is the immune response of the host that determines the outcome of infection. The most complete immune response is associated with the most severe liver injury and the greatest likelihood of viral clearance, whereas an immature immune response leads to chronic hepatitis. The natural history of chronic hepatitis B is similar to that of acute ...

Non invasive immunologic markers of virus-induced liver disease are unmet needs. We tested the clinical significance of quantitative total and IgM-anti-HBc in well characterized chronic-HBsAg-carriers. Sera (212) were obtained from 111 HBsAg-carriers followed-up for 52 months (28-216) during different phases of chronic-HBV-genotype-D-infection: 10 HBeAg-positive, 25 inactive-carriers (HBV-DNA≤2...

Hepatocellular carcinoma (HCC) is a public health problem in developing countries where chronic HBV endemic. The objective of our study was to determine the prevalence KRAS and BRAF mutations patients with HCC. Mutations codons 12 13 V600E mutation gene were searched by HRM on Light Cycler 480 confirmed direct sequencing. A total 34 HCC underwent molecular testing for codon gene. Melting curve ...

Delta antigen (delta) is a transmissible agent requiring hepatitis B virus (HBV) for its replication. Antibody to delta (anti-delta) was present in nine of 71 (13%) British HBV carriers: six were intravenous drug abusers and two were haemophiliacs. Anti-delta was negative in 30 HBsAg positive homosexuals. Cirrhosis was common in patients with anti-delta and those with anti-delta positive cirrho...

BACKGROUND AND AIM Current baseline data regarding the prevalence of hepatitis B virus (HBV) infections and the immune status in hyperendemic areas is necessary in evaluating the effectiveness of ongoing HBV prevention and control programs in northwest China. This study aims to determine the prevalence of chronic HBV infections, past exposure rates, and immune response profiles in Wuwei City, n...
