Abstract: | A large number of studies have shown that the interleukin-10 (IL-10)-1082A/G polymorphism is implicated in susceptibility to inflammatory bowel disease (IBD). However, the results are inconsistent. We performed this meta-analysis to estimate the association between -1082A/G polymorphism in the IL-10 gene and IBD susceptibility. A total number of 18 case-control studies including 17,585 subjects were identified. No association was found between -1082A/G polymorphism and ulcerative colitis (UC) susceptibility. However, increased risk of Crohn’s disease (CD) was associated with -1082A/G polymorphism in the dominant genetic model (GG + GA vs. AA: OR = 1.22, 95% CI: 1.02–1.46, P = 0.028) and the heterozygote comparison (GA vs. AA: OR = 1.28, 95% CI: 1.05–1.55, P = 0.015). The results of this meta-analysis provide evidence for the association between IL-10-1082A/G polymorphism and susceptibility of CD. Due to several limitations in the present study, well-designed epidemiological studies with large sample size among different ethnicities should be performed in the future. |
