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.

Hepatitis B Antigen and Polymyositis

JAMA: The Journal of the American Medical Association, 1978
Concomitant polymyositis diagnosed by muscle biopsy developed in a 51-year-old man with hepatitis B surface antigen (HBsAg) hepatitis. Findings from immunofluorescent studies showed deposits of gamma-globulins and complement in both muscle and liver.

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 ...

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.

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 IN COLONY MOSQUITOES

The Lancet, 1973
Abstract Aedes aegypti mosquitoes were fed on or inoculated with blood or serum positive for hepatitis-B antigen (HBAg) or allowed to feed on the arm of an HBAg carrier. Pools of mosquitoes were tested by radioimmunoassay at intervals up to 45 days after exposure to HBAg. HBAg was detected long after the blood itself would have been digested.

The nature of hepatitis B e antigen

Journal of Medical Virology, 1978
In recent years, considerable interest has developed in recognizing antigenic specificities additional to the surface antigen in the sera of patients infected with hepatitis B infection. The presence of the e-antigen appears to be invariably associated with ongoing virus replication.

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.

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).

Detection of virus antigens: Hepatitis B antigen

Metabolism, 1973
Abstract Hepatitis B virus is the infectious agent that causes hepatitis of the long incubation variety and frequently is transmitted by blood transfusions. Hepatitis B antigen (HB Ag, Australia antigen) is an immunologic marker of hepatitis B virus and is found in serum of patients with acute hepatitis and in chronic carriers.
