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

Objectives: In Greece, there are insufficient data regarding the presence of non-organ and liver-related autoantibodies in hepatitis C patients. This study in a consecutive cohort of 39 such patients from central Greece investigates (1) the prevalence of non-organ and liver-related autoantibodies, and (2) the reactivity of anti-liver-kidney microsomal type 1 antibodies (in the case of positivity with at least one of the methods used) against their molecularly defined antigens.

Design: All serum samples were tested by standard and molecular assays for the presence of anti-nuclear antibodies, smooth muscle antibodies, anti-liver-kidney microsomal type 1 antibodies, antibodies against parietal cells, anti-CYP2A6, anti-CYP1A2 and anti-CYP2D6 autoantibodies.
