Anti-GOR antibodies in lichen planus.

Anti-GOR antibodies characterize patients with autoimmune hepatitis type 2 who are all positive for antibodies to hepatitis C virus (HCV) and have low titers of anti-liver/kidney-microsomal (LKM1) antibody. The documented prevalence of anti-HCV antibodies in patients with lichen planus (LP) and chronic liver disease (CLD) and their negativity for anti-LKM1 antibodies make them eligible for having anti-GOR antibodies. We studied such a possibility in 56 LP patients. Twenty of them had also CLD. Seven CLD patients without LP served as control. Overall, 11/63 patients had anti-GOR antibodies. All of them were anti-HCV positive and had CLD. CLD patients with LP showed the same prevalence of anti-GOR antibodies as CLD patients without LP.
