Cure8 research brief
Why This Matters
Noninvasive monitoring matters for children with UC because endoscopy is burdensome. If ultrasound (and simple measures like bowel wall thickness) can reliably detect moderate-to-severe disease, families may avoid some colonoscopies and clinicians can monitor treatment response more easily.
Who Should Pay Attention
Pediatric patients with ulcerative colitis, parents and caregivers of children with UC, pediatric gastroenterologists, and researchers studying noninvasive disease monitoring.

What To Know
This prospective bicentric study in 75 children with ulcerative colitis compared three intestinal ultrasound (IUS) activity indices (MUC, UC‑IUS, Civitelli) for detecting moderate-to-severe endoscopic disease (Mayo Endoscopic Subscore ≥2). All three indices—and bowel wall thickness (BWT) alone—had similar diagnostic accuracy (AUCs ~0.76–0.80).
Adding fecal calprotectin or PUCAI to IUS produced modest, non-significant increases in accuracy. The study supports using IUS, including simple BWT measurement, as a noninvasive tool to help monitor pediatric UC. Key details - Prospective study of 75 pediatric UC patients who had IUS within 7 days of colonoscopy.
- Primary outcome: discrimination of moderate-to-severe endoscopic activity (MES ≥2) assessed by ROC/AUC. - Findings: comparable performance across three published IUS indices; greatest accuracy in severe (MES=3) disease; combined multimodal approaches showed modest additional value.
Interpretation for patients IUS appears promising as a less invasive way to track inflammation in children with UC, and a single measure like bowel wall thickness may perform nearly as well as more complex scoring systems.
Combining IUS with stool calprotectin or a clinical score (PUCAI) could slightly improve detection but did not reach statistical significance in this cohort.
Keep In Mind
Structured content depth: abstract — the classification and brief are based on the article abstract provided by the journal. The study is a moderate-sized prospective cohort (75 patients) and reports diagnostic accuracy metrics; results are promising but represent a single study and should be considered alongside other evidence and clinical judgment.

Dual Testing Strategy Linked to Long-Term Benefits in Crohn's Disease - Medscape
This study suggests using both faecal calprotectin and intestinal ultrasound together can better identify patients who reach deeper, transmural healing — and those patients had lower risk of bowel-damage progression....
Intestinal ultrasound in inflammatory bowel disease: diagnostic accuracy and impact on clinical decision making in a New Zealand tertiary centre.
Point-of-care intestinal ultrasound (IUS) showed strong agreement with follow-up tests and often changed management the same day in a New Zealand IBD cohort. Patients and clinicians may be able to use IUS to monitor...
Intestinal Ultrasound Plus Fecal Calprotectin Predicts Crohn's Recurrence | Docwire News
