PTGER4基因多态性与炎症性肠病易感性的Meta分析

摘要

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.%目的:系统评价人群中PTGER4基因多态性与炎症性肠病(Inflammatory bowel disease,IBD)的关系.方法:检索PubMed、Embase、Web of Science中2016年2月29日以前发表的相关病例对照研究文献,选择符合质量要求的研究.用STATA12.0软件进行Meta分析,计算合并OR值及其95%可信区间(Confidence interval,CI),并通过敏感性分析判断结果的稳定性,通过Egger′s检验分析发表偏倚.结果:共纳入20篇文献中发表的44项病例对照研究,包括25179例克罗恩病(Crohn′s disease,CD)病例、5261例溃疡性结肠炎(Ulcerative colitis,UC)病例和44652名对照.Meta分析结果表明,rs4613763 T/C多态性与CD关系的等位基因频率、共显性模型、显性模型、隐性模型分析的合并OR值(95%CI)分别是1.24(1.06~1.45)、1.32(1.06~1.64)、1.25(1.06~1.48)和1.28(1.03~1.59);rs17234657T/G多态性与CD关系四种模型分析合并OR值(95%CI)为:1.43(1.34~1.52)、2.12(1.70~2.63)、1.46(1.36~1.57)和1.93(1.56~2.40);rs4495224A/C多态性与CD关系的四种模型分析合并OR值(95%CI)为:1.05(0.79~1.41)、1.08(0.62~1.88)、1.12(0.75~1.65)和1.00(0.67~1.49);rs9292777G/T多态性与CD关系的四种模型分合并OR值(95%CI)为:0.77(0.67~0.88)、0.59(0.51~0.69)、0.73(0.61~0.87)和0.68(0.59~0.79);rs1373692T/G多态性与CD关系的四种模型分析并OR值(95%CI)为:1.23(0.96~1.57)、1.39(0.74~2.59)、1.26(0.74~2.13)和1.31(1.00~1.72).rs4613763T/C多态性与UC易感性分析的四种模型分析并OR值(95%CI)为:1.30(1.17~1.44)、1.73(1.16~2.59)、1.32(1.17~1.48)和1.64(1.10~2.45).结论:rs17234657 T/G、rs4613763 T/C和rs9292777 G/T多态性与CD易感性相关;rs4613763 T/C多态性与UC的易感性相关.
