简要总结
The purpose of this study is to determine the efficacy of high-dose corticosteroid pulses added to conventional oral corticosteroid course for moderate flares of ulcerative colitis.
详细描述
Oral corticosteroids (CS) are the treatment of choice for moderate flares of ulcerative colitis (UC) in patients who are on 5-aminosalicylic acid (5ASA) maintenance therapy. However, the efficacy of oral CS is limited, with up to 50% of remission rate in the available randomized controlled trials (RCTs). By the other hand, uncompleted disease remission after CS use, that is, clinical but not endoscopic remission, has been associated with a higher risk of hospitalizations and need for immunomodulator or colectomy in UC. Uncontrolled data suggests that intravenous CS (IV CS) may increase the remission rate and also reduce the proportion of patients developing steroid-dependency after the index course of CS.
The hypothesis of this study is that the addition of a 3-day high-dose IV CS pulses schedule administered in the outpatient infusion unit, added to a conventional oral CS course increases the endoscopic remission rate and reduces the 1-year proportion of patients developing steroid-dependency.
This is a randomized, phase IV, open-label, multicenter, controlled study.
The planned number of patients to be included is 148, distributed in two treatment arms (with or without initial high-dose CS pulse), and stratified regarding disease onset and mesalazine use.
The main end-point will be the proportion of patients with steroid-free, clinical and endoscopic remission at 8 and 54 weeks, with no rescue therapies.

结局指标
主要结局
Percentage of Participants With Endoscopic and Clincal Remission
时间窗: Change from baseline at week 8
The percentage of patients with steroid-free, endoscopic remission, with no rescue therapies. It has been measured by Mayo endoscopic subscore (MES). MES= 0 (no friability and granularity and intact vascular pattern). MES= 1 (mild erythema or decreased vascular pattern). MES= 2 (marked erythema, absent vascular pattern, friability, and erosions). MES= 3 (spontaneous bleeding and ulceration)
Percentage of Participants With Endoscopic and Clinical Remission
时间窗: Change from baseline at week 54
The proportions of patients with steroid-free, endoscopic remission, with no rescue therapies. It has been measured by Mayo endoscopic subscore (MES). MES= 0 (no friability and granularity and intact vascular pattern). MES= 1 (mild erythema or decreased vascular pattern). MES= 2 (marked erythema, absent vascular pattern, friability, and erosions). MES= 3 (spontaneous bleeding and ulceration)
