The diagnostic and prognostic value of pre-S(1)Ag and pre-S(2)Ab was investigated in 69 HBsAg surface antigen positive patients--14 with acute hepatitis B, 30 with chronic liver disease (six chronic persistent hepatitis, 14 chronic active hepatitis, 10 with cirrhosis) and in 25 asymptomatic carriers. Pre-S(1)Ag was found in all patients with chronic hepatitis B virus (HBV) infection regardless ...

Objective Previous reports show conflicting results regarding hepatitis B virus (HBV) vaccine efficacy in Hepatitis C (HCV) infected individuals and those with isolated core antibodies (HBcAb). We aimed to evaluate the effectiveness of HBV identify possible factors that may contribute hyporesponsivness HCV-treated patients, including HBcAb. Methods conducted a prospective study 118 enrolled chr...

IntroductionHepatitis B virus (HBV) reactivation in kidney transplant recipients has been reported 3% to 9% of anti-HBc antibody (HBcAb)-positive HBs antigen (HBsAg)-negative patients. It not studied patients receiving belatacept, a selective costimulation blocker.MethodsWe performed retrospective study all belatacept 2 transplantation centers France. Among HBcAb-positive patients, we analyzed ...

BACKGROUND The risk of infection with transfusion-transmitted viruses, such as Hepatitis B virus (HBV), has been reduced markedly. However, a zero-risk blood supply remains a popular goal. Anti-hepatitis B core antigen (anti-HBc) is considered to be an effective marker for occult HBV infection, and it has served a significant role in improving blood safety. The purpose of this study was to dete...

A 48-year-old man, who was at risk for HBV infection as he worked as a nurse in an emergency department, received HBV vaccine Recombivax (Merck-Sharp & Dohme, MSD).

BACKGROUND Haemodialysis patients are at increased risk of exposure to blood borne viruses. To reduce transmission in the UK, all haemodialysis patients are regularly screened, and if susceptible to Hepatitis B virus (HBV) infection, vaccinated. METHODS This retrospective study was undertaken to determine the HBV immune status in a large dialysis cohort and the prevalence of occult HBV infect...

Background and aims: Hepatitis B vaccination is the most successful way to prevent the virus infection. Serum concentration of vitamin D has recently been proposed as a novel predictor of response to antiviral treatment in chronic hepatitis infection. The main target of this paper was to review the recent knowledge regarding the association between obesity and vitamin D level and immune respons...
