Crohn's disease endoscopic index of severity(CDEIS) and ulcerative colitis endoscopic index of severity(UCEIS) were used for endoscopic lesion scoring. RESULTS: A total of 88 IBD patients [36 patients with Crohn's disease(CD) and 52 with ulcerative colitis(UC)] were enrolled. For CD patients, f C correlated with CDEIS(r = 0.465, P = 0.005) and CRP(r = 0.528, P = 0.001). f C levels in UC patients correlated with UCEIS(r = 0.696, P < 0.0001) and CRP(r = 0.529, P = 0.0005). Calprotectin could predict endoscopic remission(CDEIS < 6) with 50% sensitivity and 100% specificity(AUC: 0.74) in CD patients when using 918 μg/g as the cutoff. When using 191 μg/g as the cut-off in UC patients, calprotectin could be used for predicting endoscopic remission(UCEIS < 3) with 88% sensitivity and 75% specificity(AUC: 0.87). CONCLUSION: f C correlated with both CDEIS and UCEIS. f C could be used as a predictor of endoscopic remission for Asian IBD patients.展开更多
