Abstract:
Objective:To systematically review the relationship between PTGER 4 genetic polymorphisms and the risk of inflam-matory bowel disease (IBD).Methods:All eligible case-control studies which published up to February 29,2016 were searched by PubMed,Embase,Web of Science.The studies in accordance with high quality were included in this study .We synthesized pooled odds ratio ( OR) and its 95%confidence interval ( CI) using STATA12.0.The sensitivity analysis was used to determine the stability of re-sults in meta-analysis.The Egger′s analysis was performed to evaluate the publication bias .Results:Twenty original publications invol-ving 44 case-control studies were included in this study ,in which 25179 patients with Crohn′s disease (CD),5261 patients with ulcer-ative colitis ( UC) and 44652 control subjects were detected .The allelic frequency ,additive model ,dominant model and recessive mod-el were used to analyze the association of rs 4613763 T/C polymorphism and CD ,and the pooled OR and 95%CI were as followings:1.24 (1.06-1.45),1.32 (1.06-1.64),1.25 (1.06-1.48),1.28 (1.03-1.59).For rs17234657T/G polymorphism and CD,the pooled OR (95%CI) of four genetic models were 1.35 (1.28-1.47),2.12 (1.70-2.63),1.46 (1.36-1.57) and 1.90 (1.54-2.35),re-spectively.For rs4495224A/C polymorphism and CD,the pooled OR(95%CI) were 1.05 (0.79-1.41),1.08 (0.62-1.88),1.12 (0.75-1.65) and 1.00 (0.67-1.49).And the pooled OR (95%CI) were 0.77 (0.67-0.88),0.59 (0.51-0.69),0.73 (0.61-0.87),0.68 (0.59-0.79) for rs9292777G/T polymorphism and CD.For rs1373692T/G polymorphism and CD,the pooled OR (95%CI) were 1.23 (0.96-1.57),1.39 (0.74-2.59),1.26 (0.74-2.13),1.31 (1.00-1.72).The pooled OR (95%CI) of allelic fre-quency , additive model , dominant model and recessive model for the association of rs 4613763 T/C polymorphism with UC were 1.30 (1.17-1.44 ), 1.73 ( 1.16-2.59 ), 1.32 ( 1.17-1.48 ), 1.64 ( 1.10-2.45 ), respectively.Conclusion: Polymorphisms of rs17234657T/G,rs4613763T/C and rs9292777G/T are associated with CD.Polymorphism of rs4613763T/C is associated with UC sus-ceptibility.
