Cure8 research brief
If confirmed, a simple calprotectin test on fistula scrapings could help predict which Crohn’s patients are likely to heal after primary surgical fistula closure and which may need additional therapies, potentially reducing failed procedures and guiding treatment choice.
Patients with Crohn’s disease and perianal fistulas, colorectal surgeons and gastroenterologists, researchers studying perianal disease biomarkers and surgical outcomes.
This prospective study measured calprotectin in material scraped from perianal fistulas of 47 Crohn’s disease patients undergoing surgical closure (either primary closure or closure plus mesenchymal stem cell therapy).
Higher or lower scraping calprotectin levels were associated with different outcomes: lower levels were linked to successful clinical closure after primary surgery, while in the stem-cell-treated group higher scraping calprotectin was associated with radiological remission.
The study suggests that measuring calprotectin directly from fistula scrapings might help identify patients likely to succeed with primary surgical closure versus those who may need additional treatments such as mesenchymal stem cell therapy. The data come from a modest-sized, prospective cohort with median follow-up of about 18 months.
This report describes an observational clinical study of a biomarker measured by ELISA on fistula scrapings; it does not itself establish clinical practice standards. Patients and clinicians should view these findings as preliminary evidence that may guide future research and trial design, not as definitive guidance for individual treatment decisions.
This is an abstract-level summary of a prospective clinical study; results are preliminary and from a single cohort (47 patients). The assay was ELISA on scraping material and outcomes included clinical closure and MRI-based radiological remission (MAGNIFI score). Larger validation studies are needed before changing clinical practice.

Perianal fistulas are a common and morbid complication of Crohn's disease in children; a reliable, less burdensome imaging tool could help assess severity and monitor response to therapy more often than MRI.
