ABSTRACT

<p><b>OBJECTIVE</b>To investigate the relation between the alleles of HLA-DRB1*04 and outcome of HBV infection.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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< 0.01); the frequency of HLA-DRB1*0401 in groups ASC, CHB and hepatitis B cirrhosis was also higher than that of control group (20.91%, 24.49%, 22.09% respectively versus 8.62%, P< 0.05, P< 0.01,P< 0.05 respectively); the frequency of HLA-DRB1*0405 in groups ASC, CHB and hepatitis B cirrhosis was lower than that of control group (3.64%, 2.04%, 3.49% respectively versus 15.52%, P< 0.01, P< 0.01, P< 0.05 respectively ). There was no statistical significance in the allele frequency of HLA-DRB1*04 among groups ASC, CHB and hepatitis B cirrhosis (P> 0.05), and the same result was observed in different replication of HBV (P> 0.05).</p><p><b>CONCLUSION</b>HLA-DRB1*04 gene is one of the factors which determine the outcomes of HBV infection, while it has no influence on HBV replication.</p>
