Abstract:
Background:The incidence of inflammatory bowel disease(IBD)is increasing recently. However,the pathogenesis has not been fully clarified. Aims:To investigate the expressions and significance of interleukin-22( IL-22),matrix metalloproteinase-9(MMP-9)and macrophage migration inhibitory factor(MIF)in peripheral blood of patients with IBD. Methods:A total of 80 patients with IBD admitted from May 2011 to Nov. 2014 at the First Affiliated Hospital of Soochow University were enrolled,in which 43 cases were Crohn’s disease(CD),37 cases were ulcerative colitis(UC). Forty healthy subjects were served as normal controls. Peripheral levels of IL-22,MMP-9 and MIF were detected by ELISA. Multivariate Logistic regression model was used to analyze IL-22,MMP-9 and MIF in active CD and UC and ROC curve was used to evaluate the diagnostic performance of these markers for screening of active CD and UC. Results:Compared with normal control group,peripheral levels of IL-22,MMP-9 and MIF increased significantly in CD and UC groups(P <0. 05),while no significant difference was found between CD and UC groups(P > 0. 05). Peripheral levels of IL-22, MMP-9 and MIF in active CD and UC were significantly higher than those in remission stage(P < 0. 05). For screening of active IBD,the area under ROC curve(AUC)of combined detection of IL-22 and MMP-9(0. 853 for CD,0. 867 for UC) was superior to that of IL-22,MMP-9 or MIF only(0. 747,0. 770 and 0. 699 for CD,0. 774,0. 815 and 0. 761 for UC). Conclusions:Peripheral levels of IL-22,MMP-9 and MIF increase markedly in IBD patients,which are correlated closely with the activity of IBD. Combined detection of IL-22 and MMP-9 might greatly increase the accuracy for screening of active IBD.
