Deficiency of antibody formation to HBsAg in the pathogenesis of chronic hepatitis and cirrhosis?

Abstract

Sera of 832 healthy persons and patients suffering from chronic inflammatory liver disease were investigated by radioimmunoassay for HBsAg and anti-HBs. Diagnosis in patients was secured by biopsy. The persons were divided into: 1. Healthy persons: n = 478 blood donors, hospital especially exposed to HBV, patients with healed hepatitis; 2.

Patients: n = 354 acute hepatitis, chronic persistent and aggressive hepatitis, post-hepatitic, cryptogenic and alcoholic cirrhosis. The results demonstrate considerable accumulation of HBsAg in chronic liver disease (72% in CAH, 66% in posthepatic liver cirrhosis) whereas anti-HBs was more frequently observed in healthy persons (38% in hospital staff, 49% in healed hepatitis). Furthermore, HBsAg and anti-HBs were frequently observed simultaneously in chronic hepatitis and cirrhosis (23% in CAH). A strong shift in the relation of antigen to antibody to the disadvantage of antibody in the examined collectives of chronic hepatitis and cirrhosis is evident. Chronic inflammatory HBsAg positive liver disease should therefore be regarded as chronic virus infection. We suppose an absolute or relative deficiency of antibody to HBsAg is probably an important factor for the development of chronicity of hepatitis B.
