P044. Roles of IL-33 on murine colitis and M2 macrophage differentiation in inflammatory bowel diseases

displayed near perfect accuracy, as well as perfect sensitivity accompanied by high specificity.IL9 performance was expressed as overall accuracy (area under ROC curve, AUC) independent from a threshold selection, as well as sensitivity and specificity at optimal threshold yielding the highest Youden index.IL9 exhibited the strongest association with active IBD.As its marker, IL9 displayed near perfect accuracy, and its sensitivity and specificity were equally high.Conclusions: Our results demonstrate IL9 elevation in active IBD that might be used for diagnostic purposes, as well as assist in noninvasive evaluation of mucosal healing in IBD.
