摘  要:目的 探讨眼肌型重症肌无力(OMG)的临床特点及其与人类白细胞抗原(HLA) DQA1、B1基因多态性的相关性.方法 运用聚合酶链反应方法-序列特异性引物(PCR-SSP)对26例OMG、60例全身型MG(GMG)和93名健康对照(对照组)的HLA-DQA1、B1基因多态性进行分析.结果 OMG发病年龄(24.38岁)早于GMG(31.28岁;P=0.039),女性OMG发病年龄(22.21岁)亦早于女性GMG(32.92岁;P=0.016).OMG组DQB1* 0501等位基因频率(29%)明显高于GMG组(16%,P<0.05,OR=2.16,95%CI为0.99~4.68)和对照组(11%,P<0.01,OR=3.19,95%CI为1.50~6.76);GMG组DQA1* 0501(24%,P<0.05,OR=1.96,95%CI为1.09~3.53)、DQB1* 0301(23%,P<0.01,OR=2.55,95%CI为1.35~4.84)等位基因频率高于对照组(分别为14%、10%);OMG和GMG组DQA1* 0103等位基因频率(分别为4%、5%)均低于对照组(16%)(分别P=0.02,OR=0.21,95% CI为0.048~0.90; P=0.003,OR=0.27,95%CI为0.11~0.68);DQB1* 0601等位基因频率(分别为6%、7%)也均低于对照组(17%)(分别P=0.047,OR=0.31,95%CI为0.09~1.05;P=0.01,OR=0.36,95%CI为0.16~0.81).结论 OMG患者,尤其是女性OMG患者发病年龄早于GMG患者.DQB1* 0501可能是OMG患者的易感基因.Objective To investigate the relationship between the HLA-DQA1,DQB1 gene polymorphisms and pure ocular myasthenia gravis (OMG) in north China and the clinical features of these patients.Methods The HLA-DQA1,DQB1 gene polymorphisms were determined by polymerase chain reaction sequence specific primers (PCR-SSP) in 86 myasthenia gravis (MG) patients (26 OMG and 60 generalized MG)and 93 healthy subjects (the control group).The clinical characteristics of OMG and GMG patients were analyzed.The measurement data was analyzed by t-test and enumeration data by chi-square test.Results The age of OMG onset was earlier than GMG (24.38 vs.31.28,P=0.039),especially female (22.21 vs.32.92,P =0.016).The frequency of DQB1 * 0501 was significantly higher in OMG (29%) compared with GMG (16%,P〈0.05,OR=2.16,95% CI:0.99-4.68) and healthy controls (11%,P〈0.01,OR=3.19,95% CI:1.50-6.76).Compared with healthy controls (14%,10%),the frequencies of DQA1 * 0501 (24%,P〈0.05,OR=1.96,95% CI:1.09-3.53) and B1* 0301 (23%,P〈0.01,OR=2.55,95% CI:1.35-4.84) were increased in GMG.Compared with healthy controls (16%,17%),the frequency of DQA1 * 0103 (4%,5%)was significantly decreased in the two subtype of MG (P=0.02,OR=0.21,95% CI:0.048-0.90; P=0.003,OR=0.27,95% CI:0.11-0.68) and the frequency of DQB1 * 0601 (6%,7%) also significantly decreased in the two subtype of MG (P=0.047,OR=0.31,95% CI:0.09-1.05; P=0.01,OR=0.36,95% CI:0.16-0.81).Conclusions Compared with GMG patients,OMG patients have the earlier age of onset,especially in female.DQB1 * 0501 allele is positively related to the susceptibility of OMG patients.
