Efficacy and safety of oral beclomethasone dipropionate for ileal or ileal-right colon Crohn's disease of mild-to-moderate activity or in remission: Retrospective study

Efficacy and Safety of Oral Beclomethasone Dipropionate in Ulcerative Colitis: A Systematic Review and Meta-Analysis

Background and Aim

We performed a systematic review and meta-analysis of all the available evidence comparing efficacy and safety of oral prolonged released beclomethasone dipropionate (BDP) to active oral controls in patients with mild-to-moderate ulcerative colitis (UC). A subgroup-analysis compared the effectiveness of BDP and 5-ASA.

Methods

Literature research was performed in different databases, as well as manual search to identify abstracts from international meetings with data not included in extensive publications. Experts in the field and companies involved in BDP development and manufacture were contacted to identify unpublished studies used for registration purposes. Dichotomous data were pooled to obtain odds ratio meta-analysis.

Results

Five randomized controlled trials that compared oral BDP 5mg/day vs. all oral active controls in treating UC were identified as eligible. Efficacy and safety have been addressed after 4-week treatment period. One study evaluated efficacy and safety of BDP vs. prednisone and 4 of BDP vs. 5-ASA. Treatment with oral BDP 5 mg/day induces a significant better clinical response compared to oral 5-ASA (OR 1.86, 95% CI = 1.23–2.82, P = 0.003). The effect is detectable even when the comparison to prednisone is added (OR 1.41, 95% CI = 1.03–1.93, P = 0.03). Data on remission indicate that the potential clinical efficacy of BDP may be better than 5-ASA (OR 1.55, 95% CI = 1.00–2.40, P = 0.05). This difference is lost when the comparison with prednisone is added (OR 1.30, 95% CI = 0.76–2.23, P = 0.34). The safety analysis showed no differences between BDP and 5-ASA (OR 0.55, 95% CI = 0.24–1.27, P = 0.16). The lack of difference is maintained even when the study with prednisone is added (OR 0.67, 95% CI = 0.44–1.01, P = 0.06). However, the trend of difference is clear and indicates a more favourable safety profile of BDP compared to 5-ASA and PD.

Conclusions

Oral prolonged release BDP showed a superior efficacy vs. oral 5-ASA in inducing clinical improvement of mild-to-moderate UC with a similar safety profile.

Low bioavailability steroids in inflammatory bowel disease: an old chestnut or a whole new ballgame?

At present, therapy of inflammatory bowel disease is still far from being fully satisfactory; old drugs like steroids, for instance, still represent a cornerstone in the treatment of active disease despite their associated important side effects and incomplete clinical efficacy. In the last years, new therapeutic strategies have been suggested in order to avoid or at least limit steroids use and in this direction the so-called low bioavailability steroids appeared to be a promising therapeutic weapon; however, some grey areas about their real utility and manner of use still remain. The aim of this review is to evaluate the available evidence about the use of oral budesonide and beclomethasone dipropionate in inflammatory bowel disease, to critically assess their current position in the therapeutic algorithm of these diseases and to give simple and practical indications for their use in every-day clinical practice.

Oral beclomethasone dipropionate in chronic refractory pouchitis

BACKGROUND

Pouchitis is the major long-term complication after ileal-pouch anal-anastomosis for ulcerative colitis. Ten to 15% of patients develop chronic pouchitis, either treatment responsive or treatment refractory.

AIM

To evaluate the efficacy of oral beclomethasone dipropionate in inducing remission and improving quality of life in patients with chronic refractory pouchitis.

METHODS

Ten consecutive patients with active pouchitis, not responding to 1-month antibiotic treatment, were treated with beclomethasone dipropionate 10 mg⁄day for 8 weeks. Clinical, endoscopic and histological evaluations were undertaken before and after treatment, according to the Pouchitis Disease Activity Index (PDAI). Remission was defined as a combination of PDAI clinical score of ≤2, endoscopic score of ≤1 and a total PDAI score of ≤4. The quality of life was assessed with the Inflammatory Bowel Disease Questionnaire (IBDQ).

RESULTS

Eight of 10 patients (80%) achieved remission. The median total PDAI scores before and after therapy were, respectively, 12 (range 8-14) and 3 (range 2-9) (P<0.001). The median IBDQ score also significantly improved from 120 (range 77-175) to 175 (range 85-220) (p<0.001).

CONCLUSION

Eight-week treatment with oral beclomethasone dipropionate appears effective in inducing remission in patients with active pouchitis refractory to antibiotic treatment.

Oral locally active steroids in inflammatory bowel disease

IBD is a chronic and relapsing inflammatory disorder of the gut that demands long-lasting treatment targeting both flare-up periods and maintenance of remission. Oral systemic steroids have been used to induce remission in patients with active IBD for over 50 years due to their potent anti-inflammatory effects. The efficacy of systemic steroids in this setting has been largely demonstrated. However, the wide range of adverse events associated with these drugs has prompted the development of equally effective but less toxic steroid compounds. Currently, topically acting oral steroids are an important therapeutic option for Crohn's disease, ulcerative colitis and microscopic colitis, being oral budesonide and oral beclomethasone established elements of the IBD armamentarium. At present, oral budesonide is the first-line therapy to induce remission in microscopic colitis and mild to moderate ileocaecal CD patients and oral beclomethasone is effective treating mild to moderate UC patients with left-sided or extensive disease. This review aims at evaluating the current role of these compounds in IBD clinical practice.

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

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.

Nonabsorbable corticosteroids use in the treatment of gastrointestinal graft-versus-host disease

For over a decade, nonabsorbable corticosteroids have been employed in the treatment of gastrointestinal graft-versus-host-disease (GVHD) in hematopoietic stem cell transplant (HSCT), as monotherapy or in combination with systemic corticosteroids. The majority of the evidence showing a favorable outcome consisted of case series, small phase II trials and a large randomized phase III trial. The 2 most commonly studied molecules were oral budesonide and beclomethasone diproprionate. Although these reports hint at some benefit with the local treatment strategy, their methodologic inconsistencies preclude meaningful adoption to everyday clinical practice. This review evaluates the current evidence of nonabsorbable corticosteroids in HSCT and sets forth recommendations for future trials with these agents.
