title: Meta-analysis: the efficacy of rectal beclomethasone dipropionate vs. 5-aminosalicylic acid in mild to moderate distal ulcerative colitis.
abstract: BACKGROUND
  Beclomethasone dipropionate (BDP) is a second-generation steroid with topical effects and minimal systemic activity for patients with ulcerative colitis (UC).
  
  
  OBJECTIVE
  To review all available literature to assess the efficacy of enema/foam BDP compared with enema/foam 5-aminosalicylic acid (5-ASA) in the control of left-sided mild-moderate UC.
  
  
  METHODS
  We selected randomized controlled trials of enema/foam BDP compared with enema/foam 5-ASA treatment in patients with UC. Two reviewers assessed trial quality and extracted data independently.
  
  
  RESULTS
  Four trials involving 428 UC patients, 209 treated with 5-ASA (1-4 g o.d.) and 219 with BDP (3 mg o.d.), were included. Intention-to-treat analysis showed that 5-ASA induced improvement/remission of UC in 146 (69.9%) patients, while BDP in 143 (65.3%). The test for heterogeneity (Cochran Q) was not significant and Mantel-Haenszel pooled estimate of odds ratio was 1.23 (95% CI = 0.82-1.85). The results did not change when analysis was performed on a per-protocol basis.
  
  
  CONCLUSIONS
  The randomized controlled trials identified in this review showed that rectal BDP has equal effect as 5-ASA to control symptoms in UC.
