Abstract

Titres and immunoglobulin classes of autoantibodies were examined in 69 male patients with alcoholic liver cirrhosis and the findings were related to particular human leucocyte antigens and serum concentration of testosterone. Both anti-nuclear antibodies (ANA) and smooth muscle antibodies (SMA) were significantly more prevalent in patients with cirrhosis than in sex- and age-matched controls. Antimitochondrial antibodies and liver cell membrane antibody were found in 4% of the patients, and in none of the controls, but this difference was not significant. Patients with HLA-B8 and/or HLA-B12 had higher titres of ANA (n.s.) and SMA (P less than 0.05) than patients without these HLA antigens. Serum concentrations of testosterone were significantly lower in ANA-positive patients than in those negative (P less than 0.05), and a similar tendency was found in SMA-positive patients. With increasing titres of ANA the concentration of testosterone fell. Serum concentration of testosterone correlated inversely (P less than 0.05) with plasma immunoglobulin G and A. It is concluded that both genetic and hormonal factors may influence the humoral immune response in these patients.
