Beclomethasone dipropionate in Crohn's ileitis: a randomised, double-blind trial

Abstract

Background: Steroids, the mainstay of Crohn's disease treatment, have been associated with systemic side effects.

Aim: To evaluate the efficacy and tolerability of beclomethasone dipropionate for maintaining remission induced by a short course of systemic steroids in patients with Crohn's ileitis with or without right colonic involvement.

Methods: Patients (n=84) with active Crohn's disease who achieved remission during a 2-week prednisone run-in period were randomised to receive beclomethasone dipropionate for 24 weeks or continue prednisone for a further 2 weeks followed by placebo for 22 weeks. The primary outcome was relapse rate (Crohn's Disease Activity Index score>150 and an increase of ≥60 points from baseline) or withdrawal due to disease deterioration.

Results: The relapse rate was 23.3% and 53.8% in beclomethasone dipropionate and placebo groups, respectively (p=0.027). According to Kaplan-Meier analysis, the cumulative relapse rate was 38.0% in the beclomethasone dipropionate group and 56.0% in the placebo group (p=0.025). Six percent and 1.7% of all adverse events in the beclomethasone dipropionate and placebo groups, respectively, were endocrine-related.

Conclusion: These results demonstrate that beclomethasone dipropionate significantly reduces the relapse rate in post-active Crohn's ileitis patients compared with placebo after induction of remission with a short course of systemic steroids, and is well tolerated.
