J Gastroenterology:抑酸药会导致艰难梭菌感染风险增加

2019-09-18 不详 MedSci原创

质子泵抑制剂(PPIs)的使用与艰难梭菌感染(CDI)风险增加之间研究虽然有一些,但缺乏详细研究分析PPI使用对CDI感染风险的影响。因此,本项研究旨在探究PPI的剂量,持续时间和类型与CDI感染风险之间的关系。

背景
质子泵抑制剂(PPIs)的使用与艰难梭菌感染(CDI)风险增加之间研究虽然有一些,但缺乏详细研究分析PPI使用对CDI感染风险的影响。因此,本项研究旨在探究PPI的剂量,持续时间和类型与CDI感染风险之间的关系。

方法
研究人员对住院的患者进行了一项单中心队列研究。试验组的患者为包括在研究期间至少接受过一次PPI治疗的患者,并且通过随机分配指数日期来制备对照组,对照组中的患者不使用PPI。

结果
研究结果表明PPI的使用将CDI的风险增加1.8倍[95%置信区间(CI)1.5-2.2]。埃索美拉唑(95%CI 1.4-2.2)的CDI风险增加1.8倍,泮托拉唑的风险增加2.0倍(95%CI 1.5-2.8)。使用高剂量的患者比使用中等剂量的患者具有更高的风险[(HR)2.0 VS 1.3]。当PPI暴露期为6天或短于6天时,CDI的风险增加4.2倍。

结论
PPI的使用与CDI感染的发生风险增加相关,并且CDI的风险是剂量依赖性的。因此,PPI应仅以适当的剂量使用,并且仅用于必要的适应症以避免CDI风险。
