The aim of this study was to clarify the association of IL-1RN variable number of tandem repeat (VNTR) polymorphism and H. pylori infection. We performed a meta-analysis of studies retrieved by systematic searches of Pubmed, Embase and the Cochrane Library. Data were analyzed with STATA 13.1 using pooled odds ratios (ORs) with 95% confidence intervals (CIs). A total of 18 studies were included in our meta-analysis, and IL-1RN VNTR was found to be significantly associated with H. pylori infection in the comparisons of 22+2L vs. LL (OR = 1.17, 95% CI = 1.02-1.33) and 2 allele vs. L allele (OR = 1.18, 95% CI = 1.00-1.40). Stratified analyses on study designs and ethnicities were also conducted. IL-1RN VNTR was positively correlated with H. pylori infection in Asian subgroup and Hospital-Based subgroup (i.e., study samples obtained from hospital inpatients). In conclusion, our study demonstrated that IL-1RN VNTR polymorphism might increase the risk of H. pylori infection, especially in Asians.
本研究的目的是阐明白细胞介素-1受体拮抗剂（IL-1RN）可变数目串联重复序列（VNTR）多态性与幽门螺杆菌感染之间的关联。我们对通过系统检索PubMed、Embase和Cochrane图书馆获得的研究进行了荟萃分析。使用STATA 13.1软件，采用合并比值比（OR）及95%置信区间（CI）对数据进行分析。我们的荟萃分析共纳入18项研究，在22+2L与LL的比较中（OR = 1.17，95% CI = 1.02 - 1.33）以及2等位基因与L等位基因的比较中（OR = 1.18，95% CI = 1.00 - 1.40），发现IL-1RN VNTR与幽门螺杆菌感染显著相关。还对研究设计和种族进行了分层分析。在亚洲亚组和基于医院的亚组（即从医院住院患者获得的研究样本）中，IL-1RN VNTR与幽门螺杆菌感染呈正相关。总之，我们的研究表明，IL-1RN VNTR多态性可能会增加幽门螺杆菌感染的风险，尤其是在亚洲人中。
