摘要
The aim of this study was to evaluate the association between macrophage migration inhibitory factor (MIF) -173G/C (rs755622), mannose-binding lectin (MBL2) exon 1 codon 54 (rs1800450) gene polymorphisms and rheumatoid arthritis (RA) susceptibility in ethnically different populations. A meta-analysis was conducted (allelic contrast, the additive model, the dominant model and the recessive model) on the MIF-173G/C polymorphism across five studies (four European and one Asian studies), and the MBL2 codon 54 polymorphism with five studies (four Asian and one European studies), respectively. Meta-analysis indicated an association between the MIF-173G/C in all study subjects in allelic contrast (OR = 1.19, 95%CI: 1.05-1.35, P = 0.001), the additive model (OR = 1.68, 95CI: 1.13-2.49, P = 0.001), the dominant model (OR = 1.17, 95CI: 1.01-1.35, P = 0.003), the recessive model (OR= 1.63, 95CI: 1.10-2.42, P = 0.001). While stratified by ethnicity with European populations, an association was found in allelic contrast (OR = 1.20, 95CI: 1.04-1.38, P = 0.002), the additive model (OR = 1.85, 95CI: 1.19-2.88, P = 0.001), the dominant model (OR = 1.20, 95CI: 1.02-1.41, P = 0.003). With respect to MBL2 codon 54 polymorphism and RA, no association was found in all study subjects in all comparisons, but there was an association while stratified by ethnicity with Asian populations in the dominant model (OR= 1.50, 95CI: 1.01-2.23, P = 0.007). In conclusion, the present study suggests that the MIF-173G/C polymorphism is associated with RA susceptibility, but the MBL2 codon 54 polymorphism is not associated with RA.
