Aminosalicylates (5-ASA) are first-line treatment for mild-moderate ulcerative colitis (UC). Systemic corticosteroids (CS) are considered for patients in whom 5-ASA has been unsuccessful, but their use is limited by adverse effects. Beclomethasone dipropionate (BDP), a topically acting steroid with low systemic bioavailability, has a more favorable safety profile, but its role in clinical practice is not yet well established.
The aim of the present study is to assess whether oral BDP can be an alternative treatment to systemic CS for patients with mild-moderate UC not responding to first-line therapy with 5-ASA.
From 2003 to 2006, all consecutive patients with mild-moderate UC unresponsive to oral and topical 5-ASA (+/-topical CS) administered for at least 3 weeks received an 8-week course of oral BDP (10 mg/day for 4 weeks and 5 mg/day for an additional 4 weeks). Co-primary end-points were: (1) clinical remission within 8 weeks, without need of systemic CS; (2) steroid-free remission for 12 months.
Sixty-four patients were included. In this study, within 8 weeks, 48/64 patients (75%) entered remission without systemic CS, while 16/64 (25%) failed to enter remission. Within 12 months, 37/64 patients (58%) had prolonged steroid-free remission, while 11/64 (17%) relapsed. During 1 year, 75% of patients receiving oral BDP could avoid systemic CS.
Oral BDP can avoid the use of systemic CS in the vast majority of patients with mild-moderate UC not responding to 5-ASA and could be considered as a second-line treatment for these patients.
氨基水杨酸(5-ASA)是治疗轻度至中度溃疡性结肠炎(UC)的一线药物。对于那些对 5-ASA 治疗无效的患者,会考虑使用全身性皮质类固醇(CS),但由于其副作用,其使用受到限制。倍氯米松双丙酸酯(BDP)是一种具有低全身生物利用度的局部作用类固醇,具有更有利的安全性特征,但它在临床实践中的作用尚未得到充分确立。
本研究旨在评估对于对一线 5-ASA 治疗无反应的轻度至中度 UC 患者,口服 BDP 是否可以替代全身 CS 治疗。
从 2003 年到 2006 年,所有对口服和局部 5-ASA(+/-局部 CS)治疗至少 3 周无反应的轻度至中度 UC 连续患者接受了 8 周的口服 BDP 治疗(4 周每天 10mg,另外 4 周每天 5mg)。主要终点是:(1)在 8 周内无需全身 CS 即可达到临床缓解;(2)12 个月时无激素缓解。
共纳入 64 例患者。在这项研究中,在 8 周内,48/64 例(75%)患者无需全身 CS 即可进入缓解期,而 16/64 例(25%)患者未能进入缓解期。在 12 个月时,37/64 例(58%)患者出现延长的无激素缓解,而 11/64 例(17%)患者复发。在 1 年内,75%接受口服 BDP 的患者可以避免使用全身 CS。
口服 BDP 可避免大多数对 5-ASA 治疗无反应的轻度至中度 UC 患者使用全身 CS,可以将其作为这些患者的二线治疗方法。
