Gastroenterology:米索前列醇可以治疗因阿司匹林导致的小肠溃疡出血

2018-10-13 MedSci MedSci原创

阿司匹林诱导的小肠溃疡出血没有有效的治疗方法。因此,研究人员进行了一项双盲,随机,安慰剂对照试验,以确定米索前列醇是否可以治愈需要持续服用阿司匹林的小肠出血患者的小肠溃疡。

背景与目的
阿司匹林诱导的小肠溃疡出血没有有效的治疗方法。因此,研究人员进行了一项双盲,随机,安慰剂对照试验,以确定米索前列醇是否可以治愈需要持续服用阿司匹林的小肠出血患者的小肠溃疡。

方法
研究人员对84名服用阿司匹林导致小肠出血的患者进行了一项前瞻性研究,通过胶囊内镜检查发现小肠溃疡或多发糜烂的患者被随机分配到接受米索前列醇(200μg,每日4次; n = 42)或安慰剂(n = 42)组治疗8周。所有患者继续服用阿司匹林(100毫克,每日一次)。主要终点是随访胶囊内镜检查时完全溃疡愈合。次要终点包括血红蛋白水平的变化和从基线开始的溃疡/糜烂的数量变化。

结果
米索前列醇组有12例(28.6%; 95%CI,14.9%-42.2%),安慰剂组有4例(9.5%; 95%CI,0.6%-18.4%)小肠溃疡完全愈合,比例差异为19.0%(95%CI,2.8%-35.3%; P = .026)。与安慰剂组相比,米索前列醇组的血红蛋白平均增加显着更高(0.70 mg / dL; 95%CI,0.05-1.36; P = .035)。米索前列醇组中溃疡或糜烂的中等数量减少(从6.5 [1-85]到2 [0-25])显着大于安慰剂组(从7 [1-29] )到4 [0-19](P = .005)。

结论
在这项双盲,随机,安慰剂对照试验中,研究人员发现米索前列醇优于安慰剂,可促进阿司匹林使用者小肠溃疡愈合。
