Hepatitis B surface antigen monitoring and management of chronic hepatitis B
Journal of Viral Hepatitis, 2011Summary. Serum hepatitis B surface antigen (HBsAg) levels reflect intrahepatic hepatitis B virus (HBV) covalently closed circular DNA and may be a valuable addition to HBV DNA in the management of patients with chronic hepatitis B (CHB). Among HBeAg‐negative CHB patients with low HBV DNA levels, HBsAg quantification may help distinguish those with ...

Hepatitis B caused by a hepatitis B surface antigen escape mutant
Journal of Gastroenterology, 2008Amino acid substitutions within the S gene involving the major antigenic a determinant of the hepatitis B virus (HBV) surface antigen (HBsAg) have been detected in cases of failure of immunization against the virus. Our report showed development of clinical hepatitis in presence of antibody to HBsAg in a healthy individual.

Antibody to hepatitis B core antigen (anti-HBc) is a sensitive indicator of hepatitis B virus (HBV) infection. However, anti-HBc has been found in only a few patients with chronic hepatitis. Therefore, we tested for anti-HBc in 124 sera from 67 patients with histologically proven chronic hepatitis by the indirect fluorescent antibody technique.

Two commercial quantitative immunoassay platforms are currently available for the detection of hepatitis B surface antigen (HBsAg) within a wide range of concentrations: the Architect HBsAg assay and the Elecsys HBsAg II. However, there are limited data concerning their performance in patients who are positive for both HBsAg and anti-HBs antibodies. In

The clinical outcomes of hepatitis B virus (HBV) carriers are favorable following hepatitis B surface antigen (HBsAg) seroclearance. The aim of this study was to investigate the clinical course of spontaneous HBsAg seroclearance and the factors predicting it.A total of 423 patients who tested positive for HBsAg and were referred to Chiba University ...

Antigenicity of the Major Polypeptides of Hepatitis B Surface Antigen (HBsAg)
The Journal of Immunology, 1978Abstract The major polypeptides (P-1, P-2, and P-6) of HBsAg were isolated from purified preparations of 22-nm HBsAg particles, iodinated, and analyzed by double-antibody radioimmunoprecipitation assays for the presence of hepatitis B virus (HBV)-specific antigens.

Origin of salivary hepatitis B surface antigen
European Journal of Oral Sciences, 1980Abstract –Low titers of hepatitis B surface antigen (HBsAg) is often found in mixed saliva of antigenemic individuals. In the present study the occurrence of antigen in saliva was correlated to the content of albumin, which is not synthesized by the salivary glands, but represents a leakage into the oral cavity due to hemorrhage, exudation or ...

Surveillance for hepatitis B surface antigen mutants
Journal of Medical Virology, 2006Hepatitis B viral (HBV) mutants can emerge in patients as a result of selection pressure from treatment options. Some mutations that occur in the immunodominant "a" determinant of hepatitis B surface antigen (HBsAg) can present as false negative results in HBsAg immunoassays.
