Positive serum anti-nuclear antibody (ANA) and anti-smooth muscle antibody (SMA) have been reported in 10-66% of patients with chronic hepatitis C virus (HCV) infection from Western countries. However, the mechanism involved in this immunological disorder is still unknown. This study was carried out to evaluate the prevalence and clinical significance of positive serum auto-antibodies in Chinese patients with chronic hepatitis C and to assess the role of serum HCV-RNA titre and HCV genotype in the presence of serum auto-antibodies. Serum ANA, SMA and anti-mitochondrial antibody (AMA) were measured in 122 patients with chronic hepatitis C. Clinical, biochemical and virological data (serum HCV-RNA titre and HCV genotype) were compared between patients with and without serum auto-antibodies. Fifty-eight (48%) patients were associated with positive serum auto-antibodies: 42 (34%) positive for ANA, six (5%) positive for SMA, nine (7%) positive for both ANA and SMA and one (1%) positive for AMA. Clinical parameters (age, sex, blood transfusion history), liver biochemical tests, the presence of cryoglobulinaemia or cirrhosis, and the response to interferon treatment were not significantly different between patients with and without positive serum auto-antibodies. Serum HCV-RNA levels and HCV genotypes were also not significantly different between the two groups. Logistic regression analysis showed that none of the previously mentioned parameters were significant predictors to associate with serum auto-antibodies in chronic hepatitis C. We concluded that 48% of Chinese patients with chronic hepatitis C were associated with positive serum auto-antibodies. Hepatitis C virus genotypes and serum HCV-RNA levels were not correlated to the presence of serum auto-antibodies. The clinical significance and actual pathogenesis of this phenomenon remain to be clarified.
