The interleukin-6 (IL-6) C-572G gene polymorphism has been suggested to be associated with the increased coronary artery disease (CAD) risk, but the study results are still debatable. To explore the association between IL-6 C-572G gene polymorphism and CAD in the Asian population, the current meta-analysis involving 2511 subjects from 7 separate studies was conducted. The combined odds ratio (ORs) for the association between IL-6 C-572G gene polymorphism and CAD and their corresponding 95% confidence intervals (95% CIs) were assessed by random or fixed effect model. A significant association between IL-6 C-572G gene polymorphism and CAD was found in the Asian population under an allelic (OR: 1.50, 95% CI: 1.30-1.71, P<0.00001), recessive (OR: 2.221, 95% CI: 1.444-3.417, P=1.0×10(-10)) dominant (OR: 1.313, 95% CI: 1.188-1.451, P=1.0×10(-10)), homozygous (OR: 2.454, 95% CI: 1.606-3.751, P=1.0×10(-10)), heterozygous (OR: 3.01, 95% CI:1.99-4.55, P<0.00001) and additive genetic models (OR: 1.372, 95% CI: 1.231-1.528, P=1.0×10(-10)). In the Asian population, the IL-6 C-572G gene polymorphism was indicated to be correlated with CAD susceptibility. The carriers of -572G allele might be predisposed to CAD risk.
白细胞介素-6(IL-6)C-572G基因多态性被认为与冠状动脉疾病(CAD)风险增加有关,但研究结果仍存在争议。为了探讨亚洲人群中IL-6 C-572G基因多态性与CAD之间的关联,进行了本次荟萃分析,纳入了来自7项独立研究的2511名受试者。通过随机或固定效应模型评估IL-6 C-572G基因多态性与CAD关联的合并比值比(OR)及其相应的95%置信区间(95%CI)。在亚洲人群中,发现IL-6 C-572G基因多态性与CAD之间存在显著关联,在等位基因(OR:1.50,95%CI:1.30 - 1.71,P<0.00001)、隐性(OR:2.221,95%CI:1.444 - 3.417,P = 1.0×10(-10))、显性(OR:1.313,95%CI:1.188 - 1.451,P = 1.0×10(-10))、纯合子(OR:2.454,95%CI:1.606 - 3.751,P = 1.0×10(-10))、杂合子(OR:3.01,95%CI:1.99 - 4.55,P<0.00001)和加性遗传模型(OR:1.372,95%CI:1.231 - 1.528,P = 1.0×10(-10))下均如此。在亚洲人群中,IL-6 C-572G基因多态性与CAD易感性相关。-572G等位基因的携带者可能易患CAD风险。
