title: Autoantibodies, sheep cell agglutinins and anti-albumin antibodies in alcoholic liver disease.
abstract: The frequency of serum autoantibodies including anti-albumin antibodies was investigated for patients with various categories of alcoholic liver disease (ALD). The 95 patients were grouped into 3 categories: fatty liver (25 cases), alcoholic hepatitis (29 cases), and alcoholic cirrhosis (41 cases), and each group was matched with healthy controls by age, sex, ethnic origin and socio-economic status. For all patients with ALD, there was a 5-fold greater frequency over the controls of positive tests for antinuclear antibody (ANA), but titres were low; the pattern of ANA reactions was speckled in 50% of the cases. For patients with alcoholic cirrhosis, there was an 8-fold increase in frequency over the controls in anti-smooth muscle antibody (ASMA), but titres were low, pointing to a possibility that autoimmunity might be one of several determinants of progression of alcoholic hepatitis to cirrhosis. For none of the groups was there an increase over the controls in the mean titre of sheep red cell agglutinins, nor were there increased haemagglutinin titres of antibody to bovine serum albumin or to human albumin, arguing against a general increase in antibody production in ALD. Greater knowledge of the frequency, significance and pathogenicity of reactive autoantibodies which occur in response to various types of tissue damage is required for interpretation of the increase in ANA and ASMA in alcoholic liver disease.
