To evaluate the efficacy and safety of the topical corticosteroid budesonide, given in an oral controlled release formulation for maintenance of remission in patients with ileal and ileocaecal Crohn's disease (CD).
                Out of 176 patients with active CD who had achieved remission (CD activity index score < or = 150) after 10 weeks' treatment with either budesonide or prednisolone, 90 were randomised to continue with once daily treatment of 6 mg budesonide, or 3 mg budesonide or placebo for up to 12 months in a double blind, multicentre trial. Time to symptomatic relapse was calculated using Kaplan-Meier estimates. Morning plasma cortisol was measured at clinic visits and a corticotropin stimulation test was performed after three months of treatment.
                Thirty two patients were allocated to the 6 mg budesonide group, 31 to the 3 mg group, and 27 to the placebo group. After three months, 19 per cent of the patients in the 6 mg group had relapsed, compared with 45 per cent in the 3 mg group and 44 per cent in the placebo group (p = 0.047). The corresponding results after 12 months was 59 per cent in the 6 mg budesonide group, 74 per cent in the 3 mg group, and 63 per cent in the placebo group (p = 0.44). The median time to relapse or discontinuation was 258 days in the 6 mg group, 139 days in the 3 mg group, and 92 days in the placebo group (p = 0.021). Mean morning plasma cortisol values increased from entry in all three groups with no statistically significant differences at 12 months. All 13 patients remaining in the placebo group after three months had a normal corticotropin stimulation response, compared with 18 of 23 patients in the 6 mg, and 19 of 21 in the 3 mg budesonide groups (p = 0.14). Acne and moon face were slightly more common in the budesonide groups.
                6 mg budesonide once daily is significantly more efficacious than placebo in prolonging time to relapse in CD, and causes only minor systemic side effects. Osteoporosis frequently occurs in Crohn's disease, often because of corticosteroids. Budesonide as controlled release capsules is a locally acting corticosteroid with low systemic bioavailability. We investigated its effects on bone compared with prednisolone.
                In 34 international centers, 272 patients with Crohn's disease involving ileum and/or colon ascendens were randomized to once daily treatment with budesonide or prednisolone for 2 years at doses adapted to disease activity. One hundred eighty-one corticosteroid-free patients had active disease (98 had never received corticosteroids, corticosteroid naive; 83 had received corticosteroids previously, corticosteroid exposed), and 90 had quiescent disease, receiving long-term low doses of corticosteroids, corticosteroid-dependent; in 1 patient, no efficacy data were obtained. Bone mineral density and fractures were assessed in a double-blinded fashion; disease activity, side effects, and quality of life were monitored.
                Neither the corticosteroid-free nor the corticosteroid-dependent patients treated with budesonide differed significantly in bone mineral density from those receiving prednisolone. However, corticosteroid-naive patients receiving budesonide had smaller reductions in bone mineral density than those on prednisolone (mean, -1.04% vs -3.84%; P = .0084). Treatment-emergent corticosteroid side effects were less frequent with budesonide. Efficacy was similar in both groups.
                Treatment with budesonide is associated with better preserved bone mass compared with prednisolone in only the corticosteroid-naive patients with active ileocecal Crohn's disease. In both the corticosteroid-free and corticosteroid-dependent groups, budesonide and prednisolone were equally effective for up to 2 years, but budesonide caused fewer corticosteroid side effects. In previous trials, budesonide 6 mg/day was able to prolong the time to relapse in patients with quiescent Crohn's disease and budesonide 9 mg/day was effective in active disease with limited side effects. The aim of this study was to compare the effectiveness of budesonide 9 mg vs 6 mg once daily on the maintenance of remission and occurrence of adverse events.
                Double-blind, randomised trial in patients with Crohn's disease in remission. Patients were randomised to receive 6 mg/day or 9 mg/day of budesonide (Budenofalk) without concomitant treatment for Crohn's disease. Endpoints were the time to relapse and relapse rates after one year.
                Seventy-six patients were randomised to 6 mg/day and 81 patients to 9 mg/day. Survival analysis showed no differences in the time to relapse. One-year relapse rates were not significantly different (6 mg group 24%; 9 mg group 19%). Any adverse event was reported in 61 and 68% of patients in the 6 mg and 9 mg groups, respectively; none of the 12 serious adverse events were drug related.
                The one-year relapse rates were low and not significantly different between the group of patients treated with budesonide 6 mg vs 9 mg/day. Also, time to relapse and the number of adverse events were similar in both treatment groups. Steroid dependent patients with Crohn's disease are at high risk of developing glucocorticosteroid induced side effects.
                We evaluated the possibility of switching from systemic steroids to budesonide (Entocort) in prednisolone/prednisone dependent patients with inactive Crohn's disease affecting the ileum and/or ascending colon.
                Steroid dependent patients with a Crohn's disease activity index </=200 were included.
                In a double blind multicentre trial, 120 patients were randomly assigned to receive budesonide 6 mg once daily or placebo. Prednisolone was tapered to zero during the first 4-10 weeks and budesonide or placebo was given concomitantly and for a further 12 weeks. Relapse was defined as an index >200 and an increase of 60 points from baseline or withdrawal due to disease deterioration.
                After one and 13 weeks without prednisolone, relapse rates were 17% and 32%, respectively, in the budesonide group, and 41% and 65% in the placebo group (95% confidence intervals for the difference in percentages -41%, -8% and -51%, -16%; p=0.004 and p<0.001, respectively). The number of glucocorticosteroid side effects was reduced by 50% by switching from prednisolone and was similar in the budesonide and placebo groups. Basal plasma cortisol increased in both groups.
                The majority of patients with steroid dependent ileocaecal Crohn's disease may be switched to budesonide controlled ileal release capsules 6 mg without relapse, resulting in a sharp decrease in glucocorticosteroid side effects similar to placebo, and with an increase in plasma cortisol levels. Prevention of postoperative recurrence after resection for Crohn's disease (CD) would be of great clinical benefit. The efficacy of oral budesonide for prevention of endoscopic recurrence was evaluated in patients undergoing resection for ileal or ileocecal CD.
                Sixty-three patients received budesonide and 66 received placebo in a double-blind, randomized trial with parallel groups. Ileocolonoscopy, including biopsy, was performed after 3 and 12 months. Indications for surgery were fibrostenosis (78 patients), disease activity (41), and other reasons (10).
                The frequency of endoscopic recurrence did not differ between the groups at 3 and 12 months. In patients with disease activity as indication for surgery, the endoscopic recurrence rate at the anastomosis was lower in the budesonide group at 3 months, although not significantly (21% vs. 47%; P = 0.11), and at 12 months (32% vs. 65%; P = 0.047). There was no such difference with respect to fibrostenosis as indication for surgery. No differences in adverse event patterns were found between the two groups.
                Oral budesonide, 6 mg daily, offered no benefit in prevention of endoscopic recurrence after surgery for ileal/ileocecal fibrostenotic CD but decreased the recurrence rate in patients who had undergone surgery for disease activity. Budesonide is a corticosteroid with high topical anti-inflammatory activity and low systemic activity due to rapid inactivation. We have assessed the efficacy and safety of an oral controlled ileal release (CIR) preparation of budesonide for maintenance of remission in patients with ileal or ileocaecal Crohn's disease.
                In a double-blind, multicentre trial, 75 patients in clinical remission (Crohn's Disease Activity Index, CDAI, < or = 150) were randomly assigned to receive placebo, budesonide 3 mg or budesonide 6 mg daily for 12 months. Trial drugs were given at a fixed dose and without concomitant medication. The primary outcome measure was relapse, defined as a CDAI > 150 together with an increase of at least 60 units from entry. A patient was also considered to have a relapse if withdrawn from the study due to clinical deterioration, whether or not a CDAI value could be calculated at that time.
                There were no statistically significant differences in the relapse rate at any time-point throughout the study. By 12 months the proportion of patients having relapsed were 48, 46 and 60% in those patients treated with budesonide 6 mg, 3 mg and placebo, respectively (N.S.). Treatments were well tolerated, and the proportion of patients with suppressed adrenal function (according to predetermined criteria) were 50% (6 mg), 26% (3 mg) and 17% (placebo) (P = 0.096).
                In the present study, relapse rate and time to relapse were similar in the patients treated with budesonide CIR, 6 mg daily or 3 mg daily or with placebo, throughout 12 months. This is in contrast to the two previous trials with identical design, where a significant effect of budesonide CIR in prolonging the median time to relapse was found. Possible reasons for the negative results of the present study include small sample size, and the fact that there was a high placebo response. Budesonide is a corticosteroid with high topical anti-inflammatory activity and low systemic activity due to rapid hepatic metabolism. The efficacy and safety of an oral controlled-release preparation of budesonide for maintenance of remission was evaluated in patients with ileal or ileocecal Crohn's disease.
                In a double-blind, multicenter trial, 105 patients were randomly assigned to receive placebo or budesonide at doses of 3 or 6 mg daily for 1 year. The primary outcome measure was relapse defined by a Crohn's Disease Activity Index score of > 150 and a minimum increase of 60 points.
                Patients receiving 6 mg of budesonide had a median time to relapse or discontinuation of therapy of 178 days compared with 124 days in those receiving 3 mg of budesonide and 39 days in those receiving placebo. However, at 1 year, the rate of relapse in the group receiving 6 mg of budesonide was similar to the rates in the 3-mg and placebo groups. Basal plasma cortisol levels and incidence of corticosteroid-associated effects were similar in the three groups.
                Oral controlled-release budesonide (6 mg/day) was well tolerated and prolonged remission in Crohn's disease of the ileum and proximal colon, but this effect was not sustained at 1-year follow-up. The relapse rate after steroid induced remission in Crohn's disease is high.
                To test whether oral pH modified release budesonide (3 x 1 mg/day) reduces the relapse rate and to identify patient subgroups with an increased risk of relapse.
                In a multicentre, randomised, double blind study, 179 patients with steroid induced remission of Crohn's disease received either 3 x 1 mg budesonide (n = 84) or placebo (n = 95) for one year. The primary study aim was the maintenance of remission of Crohn's disease for one year.
                Patient characteristics at study entry were similar for both groups. The relapse rate was 67% (56/84) in the budesonide group and 65% (62/95) in the placebo group. The relapse curves in both groups were similar. The mean time to relapse was 93.5 days in the budesonide group and 67.0 days in the placebo group. No prognostic factors allowing prediction of an increased risk for relapse or definition of patient subgroups who derived benefit from low dose budesonide were found. Drug related side effects were mild and no different between the budesonide and the placebo group.
                Oral pH modified release budesonide at a dose of 3 x 1 mg/day is not effective for maintaining steroid induced remission in Crohn's disease. 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.
                A multicentre randomized double-blind placebo-controlled trial of 1 year duration was performed.
                Departments of surgery, endoscopy and pathology of three university hospitals participated in the trial.
                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.
                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.
                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.
                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.).
                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. To assess the efficacy and safety of budesonide capsules 6 mg daily for prolongation of time to relapse and maintenance of remission in patients with Crohn's disease (CD) affecting the ileum and/or ascending colon.
                In a double-blind, placebo-controlled, multicentre trial, 110 patients with CD, who had previously achieved remission in a placebo-controlled trial of budesonide 9 mg daily, were randomly assigned to receive budesonide 6 mg once daily or placebo for 52 weeks. Primary outcome measure was time to relapse [CD activity index (CDAI) of >150 plus an increase of at least 60 points from study entry or withdrawal due to clinical deterioration].
                Median time to relapse was 360 days for budesonide patients; 169 days for placebo patients (P = 0.132). No significant differences were seen between groups in relapse rates at 1 year. Budesonide was safe and well tolerated, with a similar adverse events profile to placebo.
                Patients treated with budesonide 6 mg once daily had a trend towards a prolonged time to relapse and lower CDAI scores compared with patients treated with placebo, but relapse rates were not significantly different at the 1-year end point. To compare the efficacy of controlled-release budesonide capsules with that of mesalamine for maintaining remission and improving quality of life (QOL) in patients with steroid-dependent Crohn's disease.
                Fifty-seven patients (25 men; mean age, 32 +/- 10.1 yr) with quiescent steroid-dependent Crohn's ileitis, ileocolitis, or colitis (Crohn's disease activity index <150) entered a prospective, investigator-blind trial. Patients were eligible for treatment with azathioprine but had not consented or had developed side effects. Patients were randomized to receive budesonide 6 mg/day (n = 29) or mesalamine 1 g 3 times/day (n = 28). Follow-up assessments were made every 2 months for up to 1 year or until relapse. At each visit, quality of life (QOL) was assessed using the Inflammatory Bowel Disease Questionnaire (IBDQ).
                There were no significant differences in baseline clinical characteristics between the study groups. The 1-year relapse rate was significantly lower in the budesonide group than in the mesalamine group (55% vs. 82%; 95% confidence interval, 12.4%-41%; P = 0.045). Patients assigned to budesonide also remained in remission longer (241 +/- 114 days vs. 147 +/- 117 days; 95% confidence interval, 32.7-155.3 days; P = 0.003). Compared with mesalamine, budesonide treatment also was associated with a better QOL throughout the study (mean total IBDQ scores 165 +/- 36 vs. 182 +/- 28, respectively; 95% confidence interval, -0.4 to 34.4, P = 0.0001). This advantage was confirmed in patients' self-assessed QOL scores.
                Over a 1-year period, controlled-release budesonide was significantly more effective than mesalamine for maintaining remission and improving the QOL of patients with steroid-dependent Crohn's disease.
Budesonide is not more effective than placebo or weaning prednisolone for maintenance of remission in Crohn's disease. Some modest benefits are noted in patients receiving budesonide compared with placebo in terms of lower CDAI scores and longer time to relapse of disease. However, these benefits are offset by higher treatment-related adverse event rates and more frequent adrenocorticoid suppression in patients receiving budesonide. Therefore, budesonide is not recommended for maintenance of remission in Crohn's disease.
