Surveillance for hepatitis B surface antigen mutants

Journal of Medical Virology, 2006
Hepatitis 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.

Hepatitis B caused by a hepatitis B surface antigen escape mutant

Journal of Gastroenterology, 2008
Amino 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.

Hepatitis B surface antigen monitoring and management of chronic hepatitis B

Journal of Viral Hepatitis, 2011
Summary.  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 ...

Antibodies. to Hepatitis B Core Antigen in Hepatitis B Surface Antigen-Positive and -Negative Chronic Hepatitis

Journal of Infectious Diseases, 1977
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.

Vertical transmission of the hepatitis B surface antigen

The American Journal of the Medical Sciences, 1975
Vertical 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 ...
