Abstract
AIM: To explore the association between macrophage migration inhibitory factor (MIF) -173G/C polymorphism and susceptibility to inflammatory bowel disease.
METHODS: Searches of electronic databases CBM, CNKI, PubMed and EMbase were performed to retrieve published case-control studies investigating the association between MIF -173G/C polymorphism and susceptibility to ulcerative colitis (UC) or Crohn's disease (CD). The pooled odds ratios (ORs) with 95% confidence intervals (95%CIs) were calculated using fixed-effect or random-effect methods based on the absence or presence of significant heterogeneity. Publication bias was assessed. All statistical analyses were conducted with STATA10.0 software.
RESULTS: Increased risk of UC was associated with MIF -173G/C polymorphism in the dominant genetic model (GG/C + C/C vs G/G: OR = 1.15, 95%CI: 1.00-1.32), the homozygote comparison (C/C vs G/G: OR = 1.54, 95%CI: 1.08-2.19) and recessive model (C/C vs G/C + G/G: OR = 1.52, 95%CI: 1.07-2.17). However, no association was found between MIF -173G/C polymorphism and susceptibility to CD.
CONCLUSION: Our meta-analysis strongly suggests that MIF -173G/C polymorphism is associated with susceptibility to UC. However, current studies do not support a direct relationship between MIF -173G/C polymorphism and susceptibility to CD.
