Abstract

The principal metabolite of ethanol, acetaldehyde, conjugates with various proteins that form antibody-inducing neo-antigens. We have analysed sera from patients with biopsy-proven alcoholic liver disease (hepatitis = 10, cirrhosis = 11, steatosis = 3) and controls = 19 (normal teetotallers and 6 non-alcoholic liver disease). Sera were examined with an enzyme-linked immunoabsorbent assay (ELISA) for antibodies binding preferentially to an acetaldehyde-albumin conjugate. Reactive sera from alcohol misusers were then purified using an amino-hexyl Sepharose affinity column. Antibodies binding to the acetaldehyde-albumin epitopes were significantly raised (P < 0.005) in all groups of alcohol misusers, and were present in greatest titre in those with alcoholic hepatitis. These antibodies were successfully purified using the gel affinity column. We conclude that alcohol misusers have significant titres of antibodies reacting to the acetaldadehyde-albumin complex. The role of these antibodies remains unclear, but may be related to the initiation of an inflammatory response and tissue damage following ethanol consumption.
