title: [Detection of anti-HCV antibody, anti-GOR antibody and autoantibodies in sera of patients with non-A, non-B liver diseases].
abstract: Anti-HCV antibody, anti-GOR antibody and autoantibodies were measured in sera of 41 patients with non-A, non-B liver diseases. Anti-HCV antibody (C100-3) was positive in 73.1% of the patients. On the other hand, anti-GOR antibody, rheumatoid factor, anti-ssDNA antibody and anti-dsDNA antibody was positive in 56%, 26.8%, 12.1% and 2.4% of the patients, respectively. In 70.7% of the patients, at least one of these four antibodies was positive. No relationship was observed in both positive rate and antibody titers among these different antibodies. On the other hand, positive rates of anti-HCV and anti-GOR antibody were higher in patients with persistently elevated serum ALT. Anti-GOR antibody appears to be a kind of autoantibody since it recognizes liver cell protein which has amino acid sequence partly similar to an epitope of HCV protein. Therefore, it could be speculated that the frequent appearance of antibodies against self constituents may be related to the chronic inflammation of the liver induced by HCV infection.
