METHODS: Low-resolution DNA typing kit was used to determine HLA-DR-1 and -DQB1 genes in 72 patients with chronic hepatitis B (CHB) and HLA-DRB1 in 200 healthy people ready to donate their bone marrow in Shanghai. Among CHB patients, 35 were treated with IFNα-1b for 24 wk. RESULTS: The frequencies of HLA-DRBI*06, DRBI*08 and DRB1*16 alleles in 72 patients were higher than in 200 healthy people (2.08% vs0%, OR = 3.837, P= 0.018; 11.11% vs5.50%, OR = 2.148, P= 0.034; and 6.94% vs 3.00%, OR = 0.625, P = 0.049, respectively); whereas that of DRBI*07 allele was lower (2.78% vs 7.75%, OR = 0.340, P= 0.046). The frequency of HLA-DRBI* 14 allele was higher in 11 responders to IFN compared with 24 non-responders (18.18% vs2.08%, OR = 10.444, P = 0.031), whereas that of DQBI*07 allele was inverse (9.09% vs37.50%, OR = 0.167, P= 0.021). CONCLUSION: The polymorphism of HLA class II may influence the susceptibility to HBV infection and the response to IFN in studied CHB patients. Compared with other HLA-DRB1 alleles, HLA-DRBI*06, DRBI*08, and DRB1*16 may be associated with chronicity of HBV infection, HLA-DRBI*07 with protection against HBV infection, and HLA-DRB1*14 allele may be associated with a high rate of the response of CHB patients to IFN treatment. Compared with other HLA-DQB1 alleles, HLA-DQBI*07 may be associated with low response rate to IFN. 2005 The WJG Press and Elsevier Inc. All rights reserved展开更多
