Abstract
Background
This meta-analysis was carried out to evaluate the associations between IL-10 polymorphisms and Kawasaki disease (KD) risk.
Methods
A comprehensive literature search was performed using PubMed, EMBASE, China National Knowledge Infrastructure and SciELO for all relevant studies evaluating IL-10 polymorphism and susceptibility to KD. The associations were measured by odds ratios (ORs) and its corresponding 95% confidence intervals (CIs).
Results
A total of 13 studies including four studies on -1082 A > G, four studies on -819 T > C and five studies on -592 A > C polymorphism were selected. Pooled data revealed that IL-10 -592 A > C polymorphism was significantly associated with an increased risk of KD (C vs. A: OR = 0.402, 95% CI 0.194–0.832, p = 0.014). However, IL-10 -1082 A > G and -819 T > C polymorphisms were not significantly associated with risk of KD under all five genetic models.
Conclusions
Our results revealed that IL-10 -592 A > C polymorphism was associated with risk of KD, while IL-10 -1082 A > G and -819 T > C polymorphisms were not involved in the development of KD.
