Mutation of the “a” Determinant of HBsAg with Discordant HBsAg Diagnostic Kits

Viral Immunology, 2004
Sera from 1003 in- and out-patients were investigated for hepatitis B surface antigen (HBsAg) mutation at Siriraj Hospital, Bangkok, Thailand. Individual samples were screened using two commercial HBsAg kits on automatic machine-based assays set up in parallel. The first kit was a sandwich ELISA kit that used monoclonal capture/monoclonal conjugate and

Effects of hepatitis B surface antigen (HBsAg) positivity of donors in HBsAg(+) renal transplant recipients: comparison of outcomes with HBsAg(+) and HBsAg(−) donors

Transplant Infectious Disease, 2016
AbstractAimThe aim of this study was to determine the effects of hepatitis B surface antigen (HBsAg) positivity of the donors on graft survival and liver complications in HBsAg(+) renal transplant recipients.Patients and methodA group of 55 patients who underwent renal transplantation (RTx) in our hospital between 2001 and 2012 were included in the ...

Polypeptide composition of HBsag

Archives of Virology, 1977
Purified HBsag has a complex structure comprising 8 polypeptides. Some of these polypeptides are immunogenic and induce both humoral and cell-mediated immunity in guinea pigs.

DETECTION OF HBsAg IN THE PANCREAS

Acta Pathologica Japonica, 1981
Hepatitis B surface antigen (HBsAg) has been reported to be present in other organs than the liver.3,9 So far as our knowledge is concerned, however, any report of cases dealing with pancreatic diseases induced by hepatitis B virus (HBV) has not been described in the English and Japanese literature.

Anti-HBe and Subtypes of HBsAg among Asymptomatic HBsAg Carriers

Vox Sanguinis, 1979
Abstract. Finnish HBsAg positive blood donors were analyzed for the HBsAg subtype distribution and the presence of e antigen (HBeAg) and antibody to e (anti‐HBe). 88% (159 of 180) of the donors had subtype ad and 12% (21 of 180) had ay. HBeAg was found in 1% (2 of 180) and anti‐HBe in 74% (133 of 180) of the donors.

Presence of HBsAg in the Bile of Subjects with Acute HBsAg Viral Hepatitis

Pathologia et Microbiologia, 2008
During acute HB_sAg serum positive viral hepatitis, the surface antigen was not detectable in duodenal bile but was almost always present in gallbladder and hepatic bile when cholecystokinin was intravenously administered. The immunologic nondemonstrability of HB_sAg in duodenal bile is probably due to the ...

Calibration of qualitative HBsAg assay results for quantitative HBsAg monitoring

Journal of Clinical Virology, 2014
Evidence is accumulating that quantitative hepatitis B surface antigen monitoring may be useful in managing patients with chronic HBV infection on certain treatment regimens. Based on these results with the Abbott Architect qualitative and quantitative HBsAg assays, it seems feasible to convert qualitative to quantitative HBsAg values for this purpose.

Quantitative Determination of the HBsAg

Vox Sanguinis, 1980
Abstract. HBsAg concentrations down to 0.05 mg/ml can be measured by a quantitative immunoelectrophoresis. By a quantitative radioimmunoassay, HBsAg concentrations from 0.001 mg to 1 mg/ml can be measured.

Circulating HBsAg/IgM complexes in chronic HBsAg carriers

Annales de l'Institut Pasteur / Virologie, 1983
Summary Sera of young male HBsAg carriers from Senegal were investigated for complexes between IgM and HBsAg. An enzyme-linked immunosorbent assay based on selective absorption of IgM was used. HBsAg/IgM complexes were detected in 14% of the HBsAg carriers.

Detection of HBsAg mutants

Journal of Medical Virology, 2006
HBsAg screening is carried out routinely to detect hepatitis B virus (HBV) infection. The immunoassays used employ capture antibodies often having specificity for epitopes present on the antigenic (a) determinant of the HBsAg. Loss of detection may occur due to mutations within and/or outside of the a determinant that affect conformational epitope ...
