Correlations between anti‐albumin antibodies and HBsAG in hepatic patients

A new category of autoantibodies--antipolymerized albumin antibodies (AAA)--was discovered in 1974. Studies performed from 1974 to 1976 showed their diagnosis and prognostic values in hepatic diseases; the AAA tests [immunodiffusion (ID) and hemagglutination (HS)] made possible a good estimation of the total liver cell function. Without being specific for a viral hepatitis B infection, highly significant linear correlations were found for AAA precipitin and agglutinin positivities with presence of HBsAg. High titre of AAA agglutinins unaccompanied by a positive ID test, characterise the "healthy carrier" of the HBsAg, while the isolated AAA positivity in ID is met in more severe, long-standing hepatic diseases.
