摘要
目的 探讨人类白细胞抗原 (HLA) DR基因编码的共同表位 (SE)与武汉籍汉族类风湿关节炎 (RA)的相关性。方法 采用聚合酶链反应 序列特异性引物技术 (PCR SSP) ,对武汉籍汉族人群 78例RA患者和 12 6例健康者的HLA DRB1 0 1、 0 4基因型进行检测。结果 RA患者中具有编码QKRAA或QRRAA的共同表位阳性率为 43 6 % ,明显高于正常对照组 (15 1% ,P <0 0 1) ;SE阳性的RA患者的关节压痛数、侵蚀性病变以及关节外表现明显高于SE阴性的RA患者(P <0 0 1)。结论 HLA DR基因编码的SE与武汉籍汉族RA易感性及疾病严重性相关 ,共同表位的检测可作为一项病情及预后判断的指标
