An essential process for resolution of viral infections is the efficient recognition and elimination of intracellular virus. Recognition of viral antigens in the form of short peptides associated with HLA class I molecule is a major task of CD8+ cytotoxic T lymphocytes. In this study, we have evaluated the frequency of the HLA class I alleles in patients with chronic hepatitis C. HLA-B51, -B52, -B55, -B56, -B61, B70, -Cw1, -Cw3, and -Cw4 are less frequent in patients with chronic hepatitis C than in Japanese individuals. The frequency of HLA-A2 is slightly lower in the patients but tends to be higher in patients with normal alanine aminotransferase (ALT) level than in those with elevated ALT level (p=0.07). Other HLA alleles are not significantly different between two groups. Cqmparison of HLA homozygosity at HLA-A and -B or -C or at two or three loci did not show a significant association with levels of serum ALT or with the clinical outcome of interferon therapy in patients with hepatitis C. These results suggest a possibility that the alterations of host response, which depends on genetic background, influence disease activities of HCV infection.
