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 ...

Hepatitis B Surface Antigen in Human Tears
Archives of Ophthalmology, 1978The incidence of hepatitis B virus infection has been increasing every year in the United States, particularly among medical personnel. Only half of these cases are associated with exposure to blood or blood products. Respiratory, fecal-oral, and venereal methods of transmission of hepatitis B virus infection are supported by epidemiological evidence ...

Hepatitis B surface antigen in the Iraqi population
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1976Using counter immunoelectrophoresis (CIEP), the carrier rate of HBsAg among the Arab Population of Iraq was found to be 2.8% comparted with 5.5% in the Kurd population. The incidence of antigenaemia in laboratory workers, renal dialysis staff and patients, nursing and blood bank staff, and pulmonary tuberculosis and diabetes mellitus patients is also ...

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 ...

Vertical transmission of the hepatitis B surface antigen
The American Journal of the Medical Sciences, 1975Vertical transmission implies transmission of the hepatitis B virus from mother to infant. This occurs with great frequency (70 to 100 per cent) when the mother has acute hepatitis B near delivery. Studies indicate that transmission may occur transplacentally or during the birth process, Once infected, the infants apparently remain hepatitis B surface ...

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.
