Active Colitis More Likely in Children in Clinical Remission Who Have PSC and IBD

A recent study (A Ricciuto et al. Clin Gastroenterol Hepatol 2018; 16: 1098-1105) provides more data regarding the lack of symptom correlation and inflammatory bowel disease (IBD) activity in children with primary sclerosing cholangitis (PSC).

In a prospective study of children with colonic IBD with and without PSC, the authors followed clinical features (eg. PUCAI), fecal calprotectin and endoscopy severity.

Key findings:

  • Patients with PSC-IBD (n=37) in clinical remission had higher endoscopic scores and greater odd of active endoscopic disease than IBD-only controls (n=50) (odds ratio 5.9, with CI 1.6-21.5)
  • Fecal calprotectin level <93 mcg/g were identified mucosal healing with 100% sensitivity and 92% specificity when compared with UC Endoscopic Index of Severity (UCEIS)

Overall, this study is in agreement with a prior adult study showing higher levels of active disease in those with PSC-IBD compared to those with IBD alone, despite clinical remission (Why does PSC increase the risk of colorectal cancer in UC?).

My take: Particularly in individuals with the combination of IBD-PSC, objective biomarkers (eg. Calprotectin) are needed to identify the accuracy of clinical remission; though, even in patients with IBD without PSC, objective biomarkers are needed as well due to the limitations of clinical symptom indices.
