Acute and chronic hepatitis B virus (HBV) infection is a leading cause of liver disease worldwide. It is estimated that approximately 350 million people worldwide have chronic HBV infection and that 1 million persons die each year from HBV-related chronic liver disease. In the past decade, significant progress in the understanding of the molecular virology and pathogenesis of HBV infection has ...

  Background and Objective: The outcome of hepatitis B virus (HBV) infection may be influenced by host factors like Human Leukocyte Antigen (HLA). We have investigated HLA-A and DRB1 alleles in patients with persistent hepatitis B infection compared to subjects who had spontaneously recovered from HBV infection. To complete the findings of this study we performed another survey in certain HLA ...

Introduction: Lichen planus is a chronic inflammatory disease in oral mucosa and skin. Recently, reports have demonstrated a possible relationship between lichen planus and liver diseases. During the past decade, there has been a hypothesis regarding viral etiological agents that have been found to be in association with hepatotrophic viruses known as Hepatitis B and C with LP. This research wa...

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...

Background & Aims HBV genotype G (HBV/G) is mainly found in co-infections with other genotypes and was identified as an independent risk factor for liver fibrosis. This study aimed to analyse the prevalence of HBV/G healthy European carriers characterize crosstalk genotypes. Methods A total 560 were tested via HBV/G-specific PCR co-infections. Quasispecies distribution analysed deep sequencing,...

AIM To evaluate pretreatment hepatitis B virus (HBV) testing, vaccination, and antiviral treatment rates in Veterans Affairs patients receiving anti-CD20 Ab for quality improvement. METHODS We performed a retrospective cohort study using a national repository of Veterans Health Administration (VHA) electronic health record data. We identified all patients receiving anti-CD20 Ab treatment (200...

    Abstract   Background: Hepatitis B virus infection is an important cause of liver morbidity and   mortality worldwide. HDV changes the natural course of HBV. The prevalence of HDV infection wasn’t determined in the various groups of HBV infection (carriers, acute hepatitis, chronic hepatitis, cirrhosis and HCC) in Iran. We aimed to research the prevalence of hepatitis D virus infection in v...

Hepatitis B virus (HBV) is prevalent worldwide and causes liver diseases, including acute and chronic hepatitis. Ten HBV genotypes (A-J) with distinct geographic distributions have been reported. Cases of acute HBV infection with genotype A have increased in Japan nationwide since the 1990s, mainly through sexual transmission. To investigate the molecular evolution and phylodynamics of HBV geno...

Background: Due to their similar routes of transmission, human immunodeficiency virus (HIV) and hepatitis B virus (HBV) co-infection occurs considerably. HBV infection progresses more rapidly in HIV-infected patients. Therefore, HBV vaccination of all non-immune HIV infected patients is recommended. On the other hand, HIV-infected subjects have suboptimal responses to HBV vaccine. In this study...

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...
