The association between interleukin-8 gene-251 A/T polymorphism and sepsis: A protocol for systematic review and meta analysis.

BACKGROUND Emerging evidence has indicated that interleukin-8 (IL-8) gene-251A/T polymorphism may affect individual susceptibility to sepsis. However, the results of published studies are inconclusive. The aim of this meta-analysis was to elucidate the association between this polymorphism and the risk and mortality of sepsis. METHODS Relevant publications were searched from PubMed, EmBase, and Web of Science databases up to January 31, 2021, with studies only in English. The reference lists of the retrieved studies were investigated as well. Pooled odds ratio (OR) with 95% confidence interval (CI) was calculated to figure out the relationship between IL-8-251 A/T polymorphisms and the risk and mortality of sepsis. All of the data were analyzed with Stata 16.0. RESULTS The results of this meta-analysis will be submitted to a peer-reviewed journal for publication. CONCLUSION This meta-analysis will summarize the relationship between IL-8-251 A/T polymorphism and the risk and mortality of sepsis.
