Hepatitis B virus (HBV) infection can cause HBV-related cirrhosis, liver failure, and hepatocellular carcinoma. At present, a hepatitis B surface antigen (HBsAg) blood test is the primary clinical and diagnostic marker for the identification of a chronic HBV infection. In the current study, we isolated a novel HBV mutant from a chronic HBV patient, capable of causing a false negative test resul...

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 analys...

BACKGROUND HBV reactivation is associated with high mortality rates in hematopoietic stem cell transplantation (HSCT) and prophylactic lamivudine (LMV) treatment is suggested to prevent this phenomenon. However, the duration of LMV treatment in HSCT patients is not fully defined and the time of immune recovery is considered the best parameter for a drug to be safely interrupted. In patients und...

Rheumatoid arthritis (RA) is a disorder with altered immunologic function and increased risks of infection, while the association between HBV and RA remains largely unknown.To determine the prevalence and risk of HBV infection in patients with RA, 2 cohort datasets were sourced from Taiwan's National Health Insurance Research Database to capture National Health Insurance claims data between 199...

We read with great interest the article, “efficacy of hepatitis B vaccine in those who lost hepatitis B surface antigen during follow-up” by Taheri et al. published in Hepatitis Monthly (1). In this article, the authors assessed the efficacy of HBV vaccine in those who lost their HBsAg without seroconverssion to anti-HBs antibody with no detectable anti-HBs antibody and HBV DNA in their sera. T...

Hepatocellular carcinoma (HCC) remains to be one of the top causing cancer-related deaths today. The majority of HCC cases are reported to be the result of chronic hepatitis B virus (HBV) infection. Current treatments for HBV-related HCC revolve around the use of drugs to inhibit viral replication, as a high level of viral load and antigen in circulation often presents a poor patient prognosis....

background and objective: although hepatitis b vaccine immunogenicity is high, certain risk factors such as age, tobacco consumption, obesity and genetic background have been associated with low responsiveness to hbv vaccine. we aimed to evaluate the role of occult hepatitis b virus (hbv) infection in non-responder adults to hbv vaccine in a low endemic area for hbv. material and methods : a to...

Occult hepatitis B virus (HBV) infections have been identified in patients with chronic hepatitis C virus (HCV) infection, although the clinical relevance of occult HBV infection remains controversial. We searched for serum HBV DNA in 106 HBsAg negative/anti-HBc positive patients with chronic HCV infection and in 150 blood donors HBsAg negative/anti-HBc positive/anti-HCV negative (control group...

CONTEXT Hepatitis B and Hepatitis C (HBV and HCV) infections are both major causes of hepatocellular carcinoma (HCC). However, HCC caused by each of these two viruses has unique characteristics that should be studied independently to that of another one. While HBV- and HCV-related HCCs share similar host and environmental risk factors such as male gender, age above 50 years old, family history ...

BACKGROUND Diagnosis of liver involvement due to schistosomiasis in asymptomatic patients from endemic areas previously diagnosed with chronic hepatitis B (HBV) or C (HCV) and periportal fibrosis is challenging. H-1 Nuclear Magnetic Resonance (NMR)-based metabonomics strategy is a powerful tool for providing a profile of endogenous metabolites of low molecular weight in biofluids in a non-invas...
