    Abstract:
    OBJECTIVE: To determine the frequency of anti-HCV antibodies, identify risk factors associated with HCV infection and to screen asymptomatic carriers in patients with lichen planus. DESIGN: A prospective study. PLACE AND DURATION OF STUDY: This study was carried out in the out patient department of Dermatology, Shaikh Zayed Hospital, Lahore, from October, 1999 to September, 2001. SUBJECTS AND METHODS: A total of 184 clinically diagnosed cases of lichen planus (LP) were selected for the study. Blood samples of all the patients were tested for anti hepatitis C virus antibodies (anti-HCV Ab). Polymerase chain reaction for hepatitis C virus was done in patients with positive anti-HCV Ab. Transcutaneous liver biopsy was performed in 7 patients with positive HCV-RNA. The histopathological results were evaluated using validated Metavir and Knodell scoring systems. RESULTS: Out of 184 LP patients, 43 (23.4%) were anti-HCV antibodies positive. Females were predominantly affected and male to female ratio was 1:5.1. Maximum positivity for anti-HCV was observed in age group 31-40 years (39.53%) followed by 41-50 years (25.58%). Eighty-one percent patients had history of dental treatment and 63% had received multiple injections for various ailments. Forty percent patients had family history of jaundice while 26% had jaundice in the past. Ten out of 16 anti-HCV antibody positive patients, checked for HCV-RNA, had high levels of virus in blood. Transcutaneous liver biopsy done in 7 patients revealed underlying liver disease at various stages. Four patients treated with alpha-interferon and ribazole therapy for liver disease, showed marked improvement in their skin disease. CONCLUSION: A high prevalence of HCV infection was detected in patients with lichen planus. Patients with lichen planus should be screened for HCV carrier state.
