The sensitivity of passive bacterial agglutination (PBA), i.e., the agglutination of Staphylococcus aureus coated with antibodies to hepatitis B surface antigen by hepatitis B surface antigen, was assessed by testing reference panel no. 3A sera (Bureau of Biologics, U.S. Food and Drug Administration). Of the 23 samples containing hepatitis B surface antigen, 18 were positive by PBA. Sera from 1...

A literature search was carried out to investigate the factors that influence the protective efficacy (PE) of hepatitis B vaccines when given to neonates of hepatitis B surface antigen and e antigen positive mothers. Hepatitis B vaccines with either high or low antigen doses are very effective in preventing chronic hepatitis B infection in neonates at risk, but there is evidence that with lower...

OBJECTIVES Living-donor kidney transplant from donors who are chronically infected with hepatitis B virus can be considered as a possibility to compensate for insufficiency of organ transplants, particularly in a hepatitis B virus endemic country. In this study, the safety and efficacy were reviewed retrospectively in living-donor kidney transplant from donors who were chronically infected with...

OBJECTIVES The aims of this study are to investigate the prevalence of occult hepatitis B virus infection among patients with cryptogenic cirrhosis and to analyze the relationship between surface protein variability and occult hepatitis B virus infection, which may be related to the pathogenesis of occult hepatitis B virus infection in cryptogenic cirrhosis. Occult hepatitis B virus infection i...
