Low-dose budesonide treatment for prevention of postoperative recurrence of Crohn's disease: a multicentre randomized placebo-controlled trial. German Budesonide Study Group

Eur J Gastroenterol Hepatol. 1999 Mar;11(3):277-82. doi: 10.1097/00042737-199903000-00011.


Objective: Endoscopic recurrence of Crohn's disease frequently occurs within weeks after 'curative' operation. Treatment with 3 x 1 mg oral pH-modified release budesonide was tried to prevent postoperative recurrence.

Design: A multicentre randomized double-blind placebo-controlled trial of 1 year duration was performed.

Setting: Departments of surgery, endoscopy and pathology of three university hospitals participated in the trial.

Patients: Patients with Crohn's disease who underwent ileal and/or colonic resection and whose anastomosis was accessible to colonoscopy were admitted to the study. Of the 88 randomized patients, 83 patients were included in the efficacy analysis (budesonide n = 43, placebo n = 40). Treatment was started within 2 weeks after surgery.

Interventions: Colonoscopy was performed 3 and 12 months postoperatively. The anastomosis and the adjacent bowel were evaluated by endoscopy and histology. For follow-up of the clinical course of the disease the Crohn's disease activity index (CDAI) was used.

Main outcome measures: The primary outcome variable was recurrence of Crohn's disease based on endoscopic findings. Secondary efficacy variables were histology scores, CDAI, time-to-failure and global judgement of well-being of the patient.

Results: The recurrence rate after 1 year (endoscopic and/or clinical) was 57% (20/35) in the budesonide group and 70% (19/27) in the placebo group (n.s.). Mean time-to-failure was 196 days under budesonide and 154 days under placebo (n.s.). Median CDAI (relapse 19% vs. 28%) and global patients' judgement at the end of treatment (bad 5% vs. 15%) was slightly in favour of budesonide. One patient in each group discontinued the trial because of adverse events. Potentially steroid-related side effects were reported more frequently in the placebo than in the budesonide group (32% vs. 17%) (n.s.).

Summary and conclusion: Although the effect of budesonide was altogether positive in almost all variables studied in this trial (e.g. endoscopic and histopathological score, time-to-failure, CDAI, patients' global judgement and rate of side effects), this increase in efficacy was small and the power for detecting differences versus placebo was too low to be statistically significant. According to these results, low-dose oral budesonide cannot be recommended to be used for the prevention of postoperative relapse in Crohn's disease.
