Efficacy and safety of rectal 5-aminosalicylic acid versus corticosteroids in active distal ulcerative colitis: a systematic review and network meta-analysis.

ABSTRACT: Topical 5-aminosalicylic acid (5-ASA) and corticosteroids are used frequently in the treatment of active distal ulcerative colitis (UC). Our study aimed to determine the efficacy and safety of different topical drugs used to treat active distal UC. A random-effects model within a Bayesian framework was utilized to compare treatment effects and safety as odds ratios (ORs) with corresponding 95% credible intervals (CrI). The surface under the cumulative ranking area (SUCRA) and median rank (MR) with corresponding 95% CrI were calculated to rank the treatment outcomes. In the induction of clinical and endoscopic remission, most regimens showed significant advantages over placebo except topical budesonide 0.5?mg/d and hydrocortisone 100?mg/d. According to SUCRA and MR values, rectal 5-ASA 1.5 to 2.0?g/d?+?Beclomethasone dipropionate (BDP) 3?mg/d rendered the highest probability of being the best regimen to achieve clinical and endoscopic remission, followed by the separate use of 5-ASA 4?g/d and BDP 3?mg/d. The occurrence of adverse events was not significantly different between each treatments and placebo. In conclusion, the combined use of topical 5-ASA and BDP proved to be the best choice for active distal UC and further well-designed researches are warranted to assess its efficacy and safety.
