Faecal Calprotectin Predicts Inflammation in Crohn’s Disease
Faecal calprotectin from ileostomy output could provide a non-invasive way to detect small-bowel inflammation after surgery, helping to guide monitoring and reduce reliance on invasive tests for postoperative Crohn’s patients.
Post-surgery Crohn’s patients with an ileostomy, clinicians who manage postoperative IBD care, researchers studying biomarkers for Crohn’s disease, and caregivers involved in monitoring recovery.
What To Know
Why it matters This report summarizes a retrospective study showing that faecal calprotectin (FC) measured from ileostomy output can distinguish active small-bowel inflammation from remission in postoperative Crohn’s disease patients.
The study compared point-of-care testing (POCT) and ELISA measurements and found both performed well with similar diagnostic accuracy. What to know A team analysed 224 FC tests from 101 Crohn’s disease patients with an ileostomy and compared results to imaging and endoscopy.
Median FC values were substantially higher when inflammation was present; the authors proposed cutoff values for POCT and ELISA that yielded high AUCs (around 0.89–0.90). The study reports no significant difference between POCT and ELISA performance, suggesting either method might be useful in clinical monitoring from ileostomy output.
Practical point For patients and clinicians, this study suggests a non-invasive way to monitor small-bowel inflammation after ileostomy that could reduce need for more invasive tests. However, the findings come from a single retrospective cohort and should be considered alongside clinical context and local testing availability.
This is a retrospective, single-cohort study; proposed cutoff values and diagnostic accuracy should be validated prospectively and in other centers before changing standard practice. The original research article (BMC Gastroenterology) is cited for full methods and detailed results.
