Increased incidence of anti-LKM autoantibodies in a consecutive cohort of hepatitis C patients from central Greece

Abstract

A relatively high incidence of anti-liver-kidney microsomal autoantibodies (10.3%) was found in a consecutive sample of Greek patients with hepatitis C. The expanded panel of assays, however, failed to document CYP2D6 as the target autoantigen of anti-liver-kidney microsomal autoantibodies in most patients. We report for the first time the detection of parietal cell antibodies and both anti-CYP2D6 (anti-liver-kidney microsomal type 1) and anti-uridine triphosphate glucuronosyltransferase (anti-liver-kidney microsomal type 3) autoantibodies in patients who were hepatitis C positive/hepatitis D negative. Further studies are needed to confirm our findings and to determine whether these preliminary results have a clinical importance or not.
