| Background: Polymorphisms in the interleukin-10 (IL-10) gene have been studied in various ethnic groups for
possible association with Behçet’s disease (BD). This study aimed to perform a meta-analysis of eligible studies to
calculate the association of IL-10 polymorphisms with BD.
A systematic literature search was carried out in PubMed, Embase, Web of Science, and Scopus databases to
identify relevant publications, and extracted the respective results. Pooled odds ratio (OR) with 95% confidence
interval (CI) was used to evaluate the power of association with a random-effects model.
Results: A total of 19 articles, consisting of 10,626 patients and 13,592 controls were included in the meta-analysis. The
meta-analysis revealed significant associations in allelic and genotypic test models of − 819 (C vs. T: OR = 0.691, P < 0.001;
CC vs. TT: OR = 0.466, P < 0.001; CC + CT vs. TT: OR = 0.692, P < 0.001; and CC vs. CT + TT: OR = 0.557, P < 0.001), − 592 (C vs.
A: OR = 0.779, P = 0.002; CC + AA vs. AA: OR = 0.713, P = 0.021; and CA vs. AA: OR = 0.716, P = 0.016), rs1518111 (G vs. A:
OR = 0.738, P < 0.001; GG vs. AA: OR = 0.570, P < 0.001; GG + AG vs. AA: OR = 0.697, P < 0.001; GG vs. GA + AA: OR = 0.701,
P < 0.001; and AG vs. GG: OR = 0.786, P = 0.004) and rs1554286 (C vs. T: OR = 0.582, P < 0.001; CC vs. TT: OR = 0.508, P < 0.001;
CC + CT vs. TT: OR = 0.605, P < 0.001; CC vs. CT + TT: OR = 0.665, P = 0.012; and CT vs. TT: OR = 0.646, P = 0.001). However, we
failed to find any association between − 1082 polymorphism and susceptibility of BD.
Conclusion: This meta-analysis demonstrated that the interleukin-10 -819, − 596, rs1518111 and rs1554286 polymorphisms
could be responsible against BD susceptibility, and should probably be regarded as a protective factor for Behçet’s disease. |
