Numerous investigations have previously evaluated the association of interleukin (IL) 4 gene polymorphisms and the risk of asthma, conferring inconsistent results. To resolve the incongruent outcomes yielded from different single studies, we conducted the most up-to-date meta-analysis of IL4 gene −589C/T (rs2243250) polymorphism and susceptibility to asthma. A systematic literature search was performed in ISI web of science, Scopus, Medline/PubMed databases prior to September 2020, and the pooled odds ratio (OR) and their corresponding 95% CI were calculated to determine the association strength. Literature search led to retrieving of 49 publications (55 case-control studies) containing 9572 cases and 9881 controls. It was revealed that IL4 gene −589C/T polymorphism increased the risk of asthma across all genetic models, including dominant model (OR = 1.22), recessive model (OR = 1.17), allelic model (OR = 1.21), and TT vs. CC model (OR = 1.34), but not the CT vs. TT model. The subgroup analysis by age indicated that IL4 gene -589C/T polymorphism was significantly associated with asthma risk in both pediatrics and adults. Additionally, the subgroup analysis by ethnicity revealed significant association in Asian, American, and Europeans. Finally, subgroup analysis by East Asian and non-East Asian populations indicated significant associations. The current meta-analysis revealed that IL4 gene -589C/T polymorphism was a susceptibility risk in both pediatrics and adults in the whole and different ethnic groups.

白细胞介素 4 基因多态性 (-589C/T) 和哮喘风险:基于 55 项研究的荟萃分析和回归分析

许多调查先前已经评估了白细胞介素 (IL) 4 基因多态性与哮喘风险之间的关联,但得出的结果不一致。为了解决不同单一研究产生的不一致结果,我们对 IL4 基因 -589C/T (rs2243250) 多态性和哮喘易感性进行了最新的荟萃分析。2020 年 9 月之前在 ISI web of science、Scopus、Medline/PubMed 数据库中进行了系统的文献检索,并计算了汇总优势比 (OR) 及其相应的 95% CI 以确定关联强度。文献检索导致检索到 49 篇出版物(55 项病例对照研究),其中包含 9572 例病例和 9881 例对照。结果表明,IL4 基因 -589C/T 多态性增加了所有遗传模型的哮喘风险,包括显性模型(OR = 1.22)、隐性模型(OR = 1.17)、等位基因模型(OR = 1.21)和TT vs. CC模型(OR = 1.34),但不包括CT vs. TT模型。按年龄进行的亚组分析表明,IL4 基因-589C/T 多态性与儿科和成人的哮喘风险显着相关。此外,按种族进行的亚组分析显示,亚洲人、美国人和欧洲人之间存在显着关联。最后,东亚和非东亚人群的亚组分析表明存在显着关联。目前的荟萃分析显示,IL4 基因-589C/T 多态性是整个和不同种族的儿科和成人的易感风险。按年龄进行的亚组分析表明,IL4 基因-589C/T 多态性与儿科和成人的哮喘风险显着相关。此外,按种族进行的亚组分析显示,亚洲人、美国人和欧洲人之间存在显着关联。最后,东亚和非东亚人群的亚组分析表明存在显着关联。目前的荟萃分析显示,IL4 基因-589C/T 多态性是整个和不同种族的儿科和成人的易感风险。按年龄进行的亚组分析表明,IL4 基因-589C/T 多态性与儿科和成人的哮喘风险显着相关。此外,按种族进行的亚组分析显示,亚洲人、美国人和欧洲人之间存在显着关联。最后,东亚和非东亚人群的亚组分析表明存在显着关联。目前的荟萃分析显示,IL4 基因-589C/T 多态性是整个和不同种族的儿科和成人的易感风险。东亚和非东亚人群的亚组分析表明存在显着关联。目前的荟萃分析显示,IL4 基因-589C/T 多态性是整个和不同种族的儿科和成人的易感风险。东亚和非东亚人群的亚组分析表明存在显着关联。目前的荟萃分析显示,IL4 基因-589C/T 多态性是整个和不同种族的儿科和成人的易感风险。
