QUANTITATIVE-ANALYSIS OF HCV RNA AND GENOTYPE IN PATIENTS
WITH CHRONIC HEPATITIS-C ACCOMPANIED BY ORAL LICHEN-PLANUS
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.
