Efficacy of tumour necrosis factor antagonists in stricturing Crohn's disease: A tertiary center real-life experience

Research output: Contribution to journalArticlepeer-review

Abstract

Background Stenosis is the most common complication of Crohn's disease (CD). Long-term outcome of patients receiving tumour necrosis factor (TNF) antagonists for such disease complication is poorly understood. Methods 51 CD patients (from July 2006 to November 2015) who had a diagnosis of small bowel or colonic stenosis, diagnosed by colonoscopy and/or MRI enterography, and were treated with TNF antagonists (adalimumab or infliximab) were enrolled. The primary outcome was to assess the rate of success of TNF antagonists on avoiding abdominal surgery for stricturing CD patients. Results 20 patients (39.2%) underwent surgery during the follow-up period. The overall incidence of abdominal surgery was 1.8 per 100 person-months at risk, while the median time to surgery was 37.9 months. The univariable and multivariable Cox's proportional hazards analysis of baseline parameters indicated that disease location (colonic vs ileal, HR: 28.2, 95% CI: 2.45–324, p = 0.007; ileocolonic vs ileal, HR: 3.38, 95% CI: 1.09–10.5, p = 0.035), prestenotic dilatation (per 1-mm increase, HR: 1.08, 95% CI: 1.01–1.15, p = 0.022) and the existence of non-perianal fistula (HR: 9.77, 95% CI: 2.99–31.9, p < 0.001) are independent risk factors for abdominal surgery. Conclusions In stricturing CD, anti-TNFs are effective in up to about two-thirds of the patients.
