摘  要:目的探讨复发性流产易感性与人类白细胞抗原(HLA)DR、DQ区域基因多态性的关系。方法采用序列特异性引物聚合酶链反应(PCR-SSP),分析200例复发性流产患者(患者组)和200例无不良妊娠史正常妇女(对照组)的DRB1和DQB1基因型。结果患者组中的DQB1*03(39.25%)等位基因频率显著高于对照组(32.5%)(P=0.047<0.05,RR=1.208),DQB1*05(14%)等位基因频率较对照组显著降低(22.75%)(P=0.001<0.05,RR=0.615);患者组中DRB1*09(14%)等位基因频率显著高于对照组(9.25%)(P=0.036<0.05,RR=1.514),DRB1*12(8.5%)等位基因频率较对照组显著降低(14%)(P=0.014<0.05,RR=0.607)。结论河南地区汉族人群中DQB1*03、DRB1*09可能是复发性流产的易感基因,而DQB1*05、DRB1*12可能对复发性流产的发生有保护作用。Objective: To investigate whether human leucocyte antigen DRB 1, DQB1 (HLA -DRB1, DQB1 ) genens polymorphism are related to the susceptibility to recurrent spontaneous abortion (RSA) patients. Methods: HLA -DRBI and HLA -DQB1 gene typings are performed by Polymerase chain reaction - specific sequence primers ( PCR - SSP) method in 200 cases of recurrent spontaneous abortion patients and 200 women with normal pregnancy history. Results: In recurrent spontaneous abortion group, the frequency of DQB1 * 03 (39. 25 % ) allele is increase significantly compared with that of controls (32. 5% ) (P = 0. 047 〈 0.05, RR = 1. 208) and the frequency of DQB1 * 05 ( 14% ) allele is decreased significantly (22. 75% ) (P = 0. 001 〈 O. 05, RR = 0. 615) ; also in RSA group, the frequency of DRB1 * 09 ( 14% ) allele is increased significantly compared with that of controls (9. 25% ) (P =0. 036 〈0. 05, RR = 1. 514) and the frequency of DRB1 * 12 (8.5%) allele is decreased significantly ( 14% ) (P = 0. 014 〈 0. 05, RR =0. 607). Conclusion: The results suggest that DQB1 * 03 and DRB1 * 09 allele may be a susceptible gene of recurrent spontaneous abortion, while DQB1 * 05 and DRB1 * 12 allele may be a protective factor for recurrent spontaneous abortion.
