Methods:
A total of 149 eligible IBD patients including 82 Crohn disease (CD) and 67 Ulcerative colitis (UC) who had received both endoscopic examination and intestinal barrier function detection in our hospital were enrolled in this study. Endoscopic activity was estimated by the Simple Endoscopic Score (SES-CD) for Crohn's Disease and the ulcerative colitis endoscopic index of severity (UCEIS) for ulcerative colitis. The predictive value and optimal predictive thresholds for those biomarkers were determined by receiver operating characteristic analysis.
Results:
For UC patients, DAO, D-lactate, and ETX showed better correlation with UCEIS than erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) and exhibited satisfactory predictive value in predicting remission. Among patients with CD, DAO and ETX not only showed a better correlation than WBC, ESR, and CRP with SES-CD but also capable to identify more severe patients.
Conclusion:
DAO and ETX could be used to distinguish different endoscopic activity of CD. DAO, D-lactate, and ETX could predict UC endoscopic remission.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
