title: Quantitative analysis of HCV RNA and genotype in patients with chronic hepatitis C accompanied by oral lichen planus.
abstract: Lichen planus (LP) is a common oral disorder that may represent a mucosal reaction to a variety of factors, including hepatitis C virus (HCV). To determine whether viral factors play a role in oral lichen planus (OLP) pathogenesis, we measured serum HCV RNA and determined HCV genotype in patients with chronic hepatitis C accompanied by OLP. The subjects included 43 patients with chronic hepatitis C: 23 with OLP (group 1) and 20 without OLP (group 2). Serum was collected from all subjects and used to quantify HCV RNA by the branched DNA signal amplification assay; HCV genotypes were classified by the reverse transcription-polymerase chain reaction (RT-PCR) method into types I, II, III and IV. Comparison of patient characteristics disclosed that the mean age of group 1, 60.7 years, was significantly higher (P = 0.001) than that of group 2 (46.4 years). No significant differences were seen between sexes in values of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), total protein (T protein), albumin and gamma-globulin. There were also no significant differences in HCV RNA levels or HCV genotypes between groups. The findings suggested that OLP pathogenesis was a result of host factors rather than viral factors.
