To investigate the association of single nucleotide polymorphisms in the HLA-DP and DQ genes with the outcome of chronic hepatitis B virus infection.
Two hundred and four healthy subjects, 255 clearance subjects, 204 asymptomatic HBV carriers (AsC), 136 chronic hepatitis B (CHB), 68 liver cirrhosis (LC) and hepatocellular carcinoma (HCC) were enrolled. Genotypes of rs3077, rs9277535 and rs2647050 were determined by sequence specific primers-PCR (PCR-SSP).
By using healthy subjects and clearance subjects as the control groups, rs3077 and rs9277535 were significantly associated with chronic HBV infection under additive and dominant models (P< 0.05). Meanwhile, haplotypes GGA, AGA, AAA appeared to be protective factors against chronic HBV infection (P < 0.05). By using AsC as the control group, comparison with the CHB, LC and HCC groups showed no association of the 3 SNPs or haplotypes with the clinical outcome (P > 0.05).
HLA-DP gene polymorphisms are strongly associated with chronic HBV infection. The presence of A allele at rs3077 and rs9277535 of the HLA-DP gene may decreased the risk for chronic HBV infection.
研究人类白细胞抗原-DP（HLA-DP）和-DQ基因单核苷酸多态性与慢性乙型肝炎病毒感染结局的相关性。
纳入204名健康受试者、255名病毒清除受试者、204名无症状HBV携带者（AsC）、136名慢性乙型肝炎（CHB）患者、68名肝硬化（LC）患者和肝细胞癌（HCC）患者。采用序列特异性引物聚合酶链反应（PCR-SSP）检测rs3077、rs9277535和rs2647050的基因型。
以健康受试者和病毒清除受试者作为对照组，在加性和显性模型下，rs3077和rs9277535与慢性HBV感染显著相关（P<0.05）。同时，单倍型GGA、AGA、AAA似乎是慢性HBV感染的保护因素（P<0.05）。以AsC作为对照组，与CHB、LC和HCC组比较，3个单核苷酸多态性或单倍型与临床结局均无相关性（P>0.05）。
HLA-DP基因多态性与慢性HBV感染密切相关。HLA-DP基因rs3077和rs9277535位点A等位基因的存在可能降低慢性HBV感染风险。
