Аннотация
The association between anticentromere antibody (ACA) and hepatitis C virus (HCV) infection remains unclear. We subjected eight patients with HCV-related chronic liver disease (CLD) seropositive for ACA to a battery of clinical and laboratory tests. The patient cohort was dominated by females, and four of the eight (50%) patients had a concomitant autoimmune disease. All of the patients had high titers of ACA (>or=1:320). The histological activity index scores in chronic hepatitis C (CH-C) patients with ACA were significantly higher than those in CH-C patients without antinuclear antibody (ANA) (12.8 +/- 1.8 vs. 8.3 +/- 4.5, P = 0.0372). The frequency of human leukocyte antigen (HLA) DR-8 in patients with HCV-related CLD seropositive for ACA was significantly higher than that in patients with CH-C seronegative for ANA (71 vs. 18%, P = 0.0108). These findings suggest that ACA is induced by chronic HCV infection in association with HLA DR-8, and that CH-C patients with ACA exhibit more severe hepatic fibrosis and inflammation than CH-C patients without ANA.
