The association of polymorphisms in programmed cell death 1 (PDCD1) gene with systemic lupus erythematosus (SLE) risk is inconsistent across different studies. This meta-analysis is aimed to provide reliable evidence to the association of five common PDCD1 polymorphisms (PD1.1, PD1.2, PD1.3, PD1.5 and PD1.6) with SLE risk. A total of 28 studies with 4,344 SLE cases and 5,474 healthy controls were included in this meta-analysis. PD1.3 polymorphism was significantly associated with SLE in the overall population (A vs. G: OR = 1.35, 95% CI = 1.12-1.63; GA vs.GG: OR = 1.41, 95% CI = 1.12-1.76; AA+GA vs. GG: OR = 1.41, 95% CI = 1.13-1.7). In the stratified analyses based on ethnicity, we found a significant association in Caucasians and in Mexicans. In the subgroup analyses by gender, a significant association was found between PD1.3 polymorphism and SLE risk in males. The results also suggested an association between the PD1.6 polymorphism and decreased SLE risk (A vs. G: OR = 0.84, 95% CI = 0.73-0.96). Our meta-analysis revealed that PD1.3 polymorphism may increase the susceptibility to SLE, particularly in Caucasians, while PD1.6 may be a protective factor to SLE.
程序性细胞死亡1(PDCD1)基因多态性与系统性红斑狼疮(SLE)风险之间的关联在不同研究中并不一致。本荟萃分析旨在为5种常见的PDCD1多态性(PD1.1、PD1.2、PD1.3、PD1.5和PD1.6)与SLE风险之间的关联提供可靠证据。本荟萃分析共纳入28项研究,包括4344例SLE患者和5474例健康对照。在总体人群中,PD1.3多态性与SLE显著相关(A与G:优势比[OR]=1.35,95%置信区间[CI]=1.12-1.63;GA与GG:OR=1.41,95%CI=1.12-1.76;AA+GA与GG:OR=1.41,95%CI=1.13-1.7)。在基于种族的分层分析中,我们发现白种人和墨西哥人中存在显著关联。在按性别进行的亚组分析中,发现PD1.3多态性与男性SLE风险之间存在显著关联。结果还提示PD1.6多态性与SLE风险降低之间存在关联(A与G:OR=0.84,95%CI=0.73-0.96)。我们的荟萃分析表明,PD1.3多态性可能增加SLE易感性,尤其是在白种人中,而PD1.6可能是SLE的一个保护因素。
