    BackgroundTo clarify the impact of IL-1B gene polymorphisms (IL-1B-511C/T, IL-1B-31C/T, IL-1B+3954C/T) in Helicobacter pylori (H. pylori) infection by mean of a meta-analysis.MethodsThe relevant studies were retrieved from PubMed, Web of Science, EMBASE, Cochrane Library, Chinese National Knowledge Infrastructure (CNKI) and Wanfang databases until September 9, 2018. Odds ratio (OR) and its 95% confidence intervals (CIs) were used to assess the associations. Statistical analyses of this meta-analysis were conducted by using STATA 12 software.ResultsTotally, 45 articles including 9606 cases and 5654 controls were enrolled in this meta-analysis. Our results indicated that IL-1B-511C/T polymorphism was significantly related to an increased the risk of H. pylori infection under recessive model (OR = 1.13, 95% CI: 1.00-1.27, P = 0.048). However, no significant associations were obtained between H. pylori infection and IL-1B-31C/T as well as IL-1B+3954C/T polymorphisms under all models. In addition, subgroup analyses were also performed by country, study design, and detection methods of H. pylori.ConclusionsThis meta-analysis suggested that IL-1B-511C/T polymorphism was related to the risk of H. pylori infection. Further larger studies with high quality are needed to conform these findings.Copyright © 2019 Elsevier Ltd. All rights reserved.
