Hepatitis B e Antigen in the Absence of Hepatitis B Surface Antigen

Journal of Infectious Diseases, 1980
Hepatitis B e antigen (HBeAg) was detected by agar gel diffusion in the serum of four Ugandan adults (three patients with tropical splenomegaly syndrome and one healthy adult) who did not have detectable hepatitis B surface antigen (HBsAg) by radioimmunoassay. Two of them had antibody to hepatitis B core antigen, and the other two had antibody to HBsAg.

The Liver and the Antigens of Hepatitis B

Annals of Internal Medicine, 1976
A decade ago an antigen was identified by immunodiffusion and subsequently proved to be closely associated with hepatitis B virus. Further studies showed that hepatitis B virus circulates as a large particle containing a protein coat and a DNA core, and that excess coat particles are produced and circulate freely.

Carbohydrates in Hepatitis B Antigen

Nature New Biology, 1973
The association between hepatitis B antigen (HB antigen; SH or Australia antigen) and long incubation period or “serum” hepatitis is well established. But the significance of HB antigen in the pathogenesis of the disease and its relationship to the infective agent, remain uncertain.

Hepatitis B Surface Antigen Seroclearance: Relationship to Hepatitis B e-Antigen Seroclearance and Hepatitis B e-Antigen-Negative Hepatitis

American Journal of Gastroenterology, 2014
The objective of this study was to determine factors associated with hepatitis B surface antigen (HBsAg) seroclearance after hepatitis B e-antigen (HBeAg) seroclearance.This is a cohort study of HBeAg-positive patients with HBeAg seroclearance. Factors associated with subsequent HBsAg seroclearance were examined.A total of 775 patients were included ...

Hepatitis B Antigen and Prevention of Post-Transfusion Hepatitis B

Vox Sanguinis, 1975
Abstract. Screening for hepatitis B antigen (HBsAg) in the serum of blood donors and exclusion of antigen‐positive blood units have reduced the frequency of post‐transfusion hepatitis but several cases of hepatitis B still occur in association with transfusions. One explanation for this is probably that HBsAg is not an indicator of infectivity.

Hepatitis B Antigen Particles and Prognosis in Hepatitis

New England Journal of Medicine, 1973
Prediction about potential chronicity of acute hepatitis, and particularly the form caused by hepatitis virus B associated with a long incubation period, is hazardous.

Differential Distribution of Hepatitis B Surface Antigen and Hepatitis B Core Antigen in the Liver of Hepatitis B Patients

Gastroenterology, 1976
One hundred liver biopsies from 100 patients with clinical presumptive diagnosis of hepatitis were examined by immunofluorescence for the presence of hepatitis B surface antigen (HBSAg) and hepatitis B core antigen (HBcAg). Of the 60 HBsAg-positive livers, 51 were diagnosed as chronic hepatitis on histological grounds, 6 as acute hepatitis, and 3 as ...

Cellular immune response to hepatitis B virus-encoded antigens in acute and chronic hepatitis B virus infection.

Journal of Immunology, 1990
The proliferative response of PBMC to hepatitis B virus (HBV) envelope, core, and e Ag was analyzed prospectively in 21 patients with acute self-limited HBV infection and compared with the response of patients with chronic HBV infection and different ...

Hepatitis B surface antigen in late hepatitis B infection

Journal of Medical Virology, 2014
Hepatitis B surface antigen (HBsAg) levels are used to evaluate and monitor clinical phases of chronic hepatitis B infection but their clinical significance is unclear in the late complications, cirrhosis of the liver and hepatocellular carcinoma. This study aimed to evaluate HBsAg levels across the whole natural history of hepatitis B virus infection,

Hepatitis B e Antigen and Infectivity of Hepatitis B Virus

Journal of Infectious Diseases, 1977
For confirmation of the difference in the infectivity of hepatitis B surface antigen (HBS Ag)-positive serum according to differences in the e antigen system, four chimpanzees were inoculated with serum positive for hepatitis B e antigen (HBe Ag), and three chimpanzees were inoculated with serum positive for antibody to HBe Ag (anti-HBe).
