UNLABELLED Background The characteristics associated with incident hepatitis B (HBV) infection in HIV-positive individuals are not well described in the Australian setting. The aim of this study is to determine the characteristics of and risk factors for HBV infection within HIV-infected individuals in a Melbourne cohort between 1985 and 2011. METHODS Individuals susceptible to HBV at their H...

BACKGROUND Hepatitis B virus (HBV) is the major cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma. The global epidemiological scenario of HBV infection has been changing rapidly over the last two decades due to an effective immunization programme initiated by the World Health Organization. The objective of this study is to estimate the prevalence of HBV in apparently healthy y...

We greatly enjoyed reading the excellent review by Hollinger and colleagues on occult hepatitis B infection in chronic hemodialysis (HD) patients (1). As Hollinger et al. mentioned in their review, few studies have shown the prevalence of occult hepatitis B virus (HBV) infection in HD patients. Due to the parenteral transmission of HBV, HD patients are at high risk of acquiring this virus becau...

Over the past decades, the risk of HBV transfusion-transmission has been steadily reduced through the recruitment of volunteer donors, the selection of donors based on risk-behavior evaluation, the development of increasingly more sensitive hepatitis B antigen (HBsAg) assays, the use of hepatitis B core antibody (anti-HBc) screening in some low-endemic countries, and the recent implementation o...

the transfusion transmitted infections are potentially dangerous complications of transfusion therapy in immunocompromised patients. the aim of this study was to determine the prevalence of transmissible infections in blood donor population in kashan, iran. a total of 600 consecutive sera were tested for cmv-igm antibody, hbsag, hepatitis b core (hbc) antibody, hepatitis c (hcv) antibody, and h...

In this cross sectional anonymous study, blood samples of 285 dentists and Physicians were tested for hepatitis B surface antigen (HBs Ag), hepatitis B envelope Ag (HBe Ag), antibodies to: hepatitis B suface (anti-HBs), hepatitis B core Ag (anti-HBc) and hepatitis B envelope Ag (anti-HBe) by ELISA-3 and antibody to hepatitis C virus (anti-HCV) by ELISA-3 and immunoblotting tests. The results su...

Human hepatitis B virus (HBV), the prototype of hepadnavirus family is a small-enveloped virus that replicates by reverse transcription within hepatocytes of an infected individual (Loeb and Ganem, 1993; Nassal and Schaller, 1993). It causes a variety of acute and chronic liver diseases including hepatocellular carcinoma (HCC) and cirrhosis in human and in other higher primates such as chimpanz...

Hepatitis B virus (HBV) infection is a major global health problem. Currently-available therapies are ineffective in curing chronic HBV infection. HBV and its satellite hepatitis D virus (HDV) infect hepatocytes via binding of the preS1 domain of its large envelope protein to sodium taurocholate cotransporting polypeptide (NTCP). Here, we developed novel human monoclonal antibodies that block t...

BACKGROUND Rituximab has been associated with hepatitis B virus reactivation (HBV-R). However, the characteristics and scope of this association remain largely undefined. METHODS We completed a comprehensive literature search of all published rituximab-associated HBV-R cases and from the Food and Drug Administration (FDA) Adverse Event Reporting System (AERS) MedWatch database. Literature and...
