Background: The risk of infection by transfusion-transmitted viruses has been reduced remarkably. However, a zero-risk blood supply is still desirable. The screening for antibody to HBc (anti-HBc) has been shown as an alternative test for the detection of HBV infection. Objective: The main aim of this study was to evaluate HBV infection markers and the potential value of anti-HBc testing of blo...

INTRODUCTION We aimed to evaluate the prevalence of "anti-HBc alone" among Syrian blood donors, highlighting the possibility of representing occult HBV infection. METHODOLOGY Sera of 3,896 healthy blood donors were tested for both HBsAg and anti-HBc. HBsAg-negative, anti-HBc-positive samples were further tested for the antibodies to HBsAg (anti-HBs), and "anti-HBc alone" sera were tested for ...

The impact of antibodies to hepatitis B core antigen (anti-HBc) on survival after curative surgical resection (SR) for hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) remains unclear. The aim of the present study was to examine the relationship between anti-HBc positivity and survival of HCV-related HCC patients who underwent curative SR. A total of 222 patients with HCV-related,...

Background. During routine donor screening in the blood bank, it is not uncommon to find isolated reactivity for anti-HBc in the absence of detectable HBV DNA in a first donation but absence of reactivity to anti-HBc in subsequent donations, suggesting a false-positive result for anti-HBc. Study Design and Methods. The blood donor population was screened between January 2010 and October 2011. W...

QUESTIONS UNDER STUDY The risk of transfusion-transmitted HBV remains significant in Switzerland, where routine screening for hepatitis B virus (HBV) in blood donations relies solely on serological hepatitis B surface antigen (HBsAg) testing. This study was designed to determine the prevalence of anti-hepatitis B core (anti-HBc) and HBV nucleic acid testing (NAT) positive donations in two diffe...

BACKGROUND & OBJECTIVE Though sensitive screening assays for detection of hepatitis B virus surface antigen (HBsAg) are available, occasional cases of post-transfusion hepatitis B virus infection (PTH) still occur. The present study was undertaken to assess the prevalence of anti-hepatitis B core (anti-HBc) positivity and presence of HBV-DNA in serum sample of healthy blood donors negative for ...

A meta-analysis was performed to ascertain to what extent hepatitis B surface antigen (HBsAg)-negative/anti-hepatitis B core (anti-HBc)-positive subjects with chronic liver disease are at a higher risk of developing hepatocellular carcinoma (HCC) than the anti-HBc-negative.All studies included had to fulfill the following characteristics and inclusion criteria: they investigated the relationshi...

BACKGROUND & AIMS Although hepatitis B virus (HBV) transmission after liver transplantation of grafts from HBsAg-negative, anti-HBc positive donors is well established, the growing organ shortage favours the use of such marginal grafts. We systematically evaluated the risk of HBV infection after liver transplantation with such grafts and the effect of anti-HBV prophylaxis. METHODS We performe...

background and objective: presence of hepatitis b core antibody (anti-hbc) in the absence of hepatitis b surface antigen (hbsag) and hepatitis b surface antibody (anti-hbs) is defined, as isolated anti-hbc. little is known about the clinical significance of the isolated anti-hbc in hepatitis b virus (hbv) infections. the aim of this study was to assess the significance of anti-hbc as the only m...
