New Intestinal Ultrasound Score for Assessing Inflammatory Bowel Disease Activity and Identifying Severity.

Area of Science:

• Gastroenterology
• Medical Imaging
• Diagnostic Tools

Background:

• Inflammatory bowel disease (IBD) diagnosis and monitoring often rely on invasive procedures.
• Accurate assessment of IBD activity and severity is crucial for effective treatment.

Purpose of the Study:

• To develop novel ultrasound-based scores for evaluating inflammatory bowel disease (IBD) activity.
• To determine the accuracy of these scores in assessing IBD severity.
• To validate the utility of intestinal ultrasound as a non-invasive follow-up tool for IBD.

Main Methods:

• Intestinal ultrasound was performed on 136 adult IBD patients (93 UC, 43 CD).
• Patients were categorized into active and inactive disease groups based on colonoscopy.
• Receiver operating characteristic (ROC) analysis was used to calculate cut-off values, sensitivity, and specificity for the developed scores.

Main Results:

• Higher bowel wall thickness (BWT) and vascular index (VI) were observed in active disease groups for both UC and CD.
• Specific ultrasound findings (CEUS modes III-IV, CDFI grades 3-4, fat wrapping, lost stratification) correlated with active disease.
• Young's modulus was significantly higher in active UC patients compared to inactive UC patients.

Conclusions:

• Novel ultrasound scores effectively assess disease activity in both ulcerative colitis (UC) and Crohn's disease (CD).
• These scores show potential for identifying severe endoscopic activity in IBD patients.
• Intestinal ultrasound serves as a valuable tool for monitoring IBD progression and activity.
