[Association of polymorphism on HLA-DRB1*04 alleles with outcome of hepatitis B virus infection].

OBJECTIVE: To investigate the relation between the alleles of HLA-DRB1*04 and outcome of HBV infection. METHODS: The alleles of HLA-DRB1*04 were detected by polymerase chain reaction-sequence specific primer (PCR-SSP). The frequency of allele of HLA-DRB1*04 in four groups[106 asymptomatic HBsAg carriers (group ASC), 93 chronic hepatitis B patients (group CHB), 77 patients with hepatitis B cirrhosis and 102 cases of spontaneous recovery after HBV infection (control group)] were studied, and the frequency of that in different replication of HBV was also studied. RESULTS: The frequency of allele of HLA-RB1*04 in groups ASC, CHB and hepatitis B cirrhosis was markedly higher than that of control group (25.94%, 26.34%, 27.92% respectively versus 14.22%, P 0.05), and the same result was observed in different replication of HBV (P> 0.05). CONCLUSION: HLA-DRB1*04 gene is one of the factors which determine the outcomes of HBV infection, while it has no influence on HBV replication.
