OBJECTIVE There is a significant risk of hepatitis B transmission from HBsAg (-), HBcAb (+) donors in liver transplantation, but there is little information about hepatitis B transmission from HBcAb heart donors. The present study examines the influence of HBcAb presence in relation to heart donor acceptance and offers an update of the published studies. DESIGN Survey and medical database upd...
BACKGROUND & AIMS The systematic use of rapid tests performed at points-of-care may facilitate hepatitis B virus (HBV) screening and substantially increase HBV infection awareness. The aim of this study was to evaluate the effectiveness of such tests for HBsAg and anti-HBsAb detection among individuals visiting a variety of healthcare centers located in a low HBV-prevalent area. METHODS Three...
An epidemiological study of hepatitis viruses type B (HBV) and type C (HCV) and human T-cell leukemia virus type I (HTLV-I) was carried out among 105 residents (male:female=19:86) regarded as Nenets partly mixed with Komi, in the region of Krasnoe, the Nenets Autonomous District of the Arkhangelsk Region, in northwestern Russia in 2004. Blood was drawn from apparently healthy volunteers at ages...
Rituximab is a monoclonal antibody that targets B-lymphocytes, and it is widely used to treat non-Hodgkin's lymphoma. However, its use has been implicated in HBV reactivation that's related with the immunosuppressive effects of rituximab. Although the majority of reactivations occur in hepatitis B carriers, a few cases of reactivation have been reported in HBsAg negative patients. However, reac...
We determined the seroprevalence of hepatitis B in Nahavand in a sample of 1824 subjects > 5 years in 2002. Face-to-face interviews were conducted and blood samples taken. The association between risk factor and hepatitis B was assessed using logistic regression. The prevalence of HBsAg positive cases was 2.3%, and HBcAb and HBsAb were isolated in 7.8% and 11.6% of the participants respectively...

Background: Regarding the availability of an effective vaccine against hepatitis B virus, global vaccination is the best cost-effective strategy to prevent HBV infection. However, some people may not respond to the vaccine or the titer of antibody decreases by time. Therefore, the present study aimed to determine the frequency of anti-HBs antibody (anti-HBsAb), among university students in Fa...
BACKGROUND About ninety percent of immunocompetent adults recover from hepatitis B virus (HBV) infection within 6 months after transmission. The infection is considered to be terminated if the antibodies (HBsAb) to the hepatitis B surface antigen (HBsAg) become detectable and the HBsAg and Hepatitis B virus DNA (HBV DNA,) are no longer perceptible. After recovery from an acute infection, the de...
BACKGROUND The aim of this study was to investigate the hepatitis B virus (HBV) infection rate in systemic lupus erythematosus (SLE) patients in China, and to determine the age and sex distribution. MATERIAL AND METHODS A total of 3981 SLE patients diagnosed in The First Affiliated Hospital of Sun Yat-sen University from January 1996 to December 2011 were retrospectively investigated for eval...
The objective of this study was to determine long-term immunity to hepatitis B virus (HBV) in a cohort of adolescents who received plasma-derived HBV vaccine in 1989 and 1990 in a remote Australian Aboriginal community. This was done using a serological survey; primary outcome measures were cut-off titres of HBsAb, and the presence of HBcAb and/or HBsAg. Of 37 adolescents in the cohort, 4 (11%)...
