Neonatal hepatitis associated with Australia antigen (Au-1).

Australia Antigen (a Hepatitis-associated Antigen)

Australia antigen [Au(1)], a particle associated with viral hepatitis, was isolated from the plasma of a patient with chronic anicteric hepatitis and leukemia who had received radioactive phosphorus. We have found that the immunoreactivity and appearance of Au(1) in the electron microscope were not altered by treatment with enzymes including trypsin, pronase, lipase, phospholipase C, ribonuclea...

Cirrhosis associated with the Australia antigen in an infant who acquired hepatitis from her mother.

A 19-week-old English girl developed acute viral hepatitis, which became chronic with persistent hepatosplenomegaly and abnormal liver function tests. Liver biopsy at 1 year showed an active cirrhosis with multinucleated giant cells. The Australia (Au) antigen was detected repeatedly in the infant's serum by immunodiffusion and by electron microscopy at the time of the acute attack and during t...

Hepatitis-associated antigen in patients with cancer.

The hepatitis-associated antigen (HAA) (Australian antigen) is either the infective agent of viral hepatitis or a virus-related protein(l). It is present in the blood during the incubation period and early clinical course of acute viral hepatitis in adults(l,2). The presence of the HAA in Krugman's long incubation hepatitis (MS-2) and its absence in childhood hepatitis, epidemic hepatitis, and ...
