In this meta-analysis, we investigated the association between CTLA-4 polymorphisms (CT60A/G, -1722T/C, -1661G/A, and -318C/T) and SLE susceptibility. Data were extracted independently by two reviewers. The odds ratios (ORs) with 95% confidence intervals (CIs) were calculated in fixed or random effects models. Seventeen studies involving of 3931 cases and 4619 controls were identified. Significant association of promoter -1722T/C polymorphism and SLE was observed for TT vs. CC (OR=1.63, 95% CI 1.63-2. 30, P<0.05) in the overall study population and in the Asians subgroups (OR=2. 18, 95% CI 1.70-2. 81, P<0.05); the OR for the allele T vs. C in Asians was 1.66 (95% CI 1.33-2. 07, P<0.05). For the CT60A/G polymorphism, significant association was observed for AA vs. AG (OR=0.64, 95% CI 0.46-0.88, P<0.05) in Asians. These results suggest that -1722T/C and CT60A/G polymorphisms in CTLA-4 are associated with SLE, particularly in Asians.
在这项荟萃分析中，我们研究了细胞毒性T淋巴细胞相关抗原4（CTLA-4）基因多态性（CT60A/G、-1722T/C、-1661G/A和-318C/T）与系统性红斑狼疮（SLE）易感性之间的关联。两名审阅者独立提取数据。采用固定效应模型或随机效应模型计算比值比（OR）及95%置信区间（CI）。共纳入17项研究，涉及3931例病例和4619例对照。在总体研究人群和亚洲亚组中，观察到启动子-1722T/C多态性与SLE存在显著关联，TT与CC相比（OR=1.63，95%CI 1.63-2.30，P<0.05）；亚洲亚组中，等位基因T与C相比的OR为1.66（95%CI 1.33-2.07，P<0.05）。对于CT60A/G多态性，在亚洲人中观察到AA与AG相比存在显著关联（OR=0.64，95%CI 0.46-0.88，P<0.05）。这些结果表明，CTLA-4基因中的-1722T/C和CT60A/G多态性与SLE相关，尤其是在亚洲人中。
