Hepatitis B virus antigens in liver tissue in hepatocellular carcinoma and advanced chronic liver disease-relationship to liver cell dysplasia.

Liver, 2008
Hepatitis B surface (HBs) and core (HBc) antigens (Ag) were studied in liver tissue in HBsAg seropositive patients with chronic liver disease complicated (n = 32) and not complicated (n = 36) by hepatocellular carcinoma.

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.

Contribution of human leukocyte antigens to the antibody response to hepatitis B vaccination.

Tissue Antigens, 1997
We present here the analysis of 86 individuals who were true antibody nonresponders to a vaccine containing hepatitis B surface antigen. The HLA type of these individuals and of 248 controls were determined by serology for HLA class I and by molecular ...

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 ...

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.
