Drug Safety:PPI使用与痴呆风险之间的相关性或被高估

发表在《Drug Saf》的使用2002~2013年韩国医疗数据库进行的处方序列对称性分析(PSSA),表明质子泵抑制剂(PPI)的使用和痴呆风险之间的相关性不确定。

发表在《Drug Saf》的使用2002~2013年韩国医疗数据库进行的处方序列对称性分析(PSSA),表明质子泵抑制剂(PPI)的使用和痴呆风险之间的相关性不确定。

介绍:研究已经发现,PPI的使用与痴呆之间具有相关性,但是这些结果可能因选择偏倚所混杂。

目的:研究者使用PSSA评估了PPI vs组胺-2受体拮抗剂(H2RAs,阳性比较组)和痴呆之间的序列比对(SR)。

方法:研究者利用2002~2013年韩国医疗数据库进行了PSSA。暴露定义为新PPI使用者,结局定义为新痴呆诊断(国际疾病和相关健康问题统计分类第10版[ICD-10]编码F00-03、F05.1、G30、G31.1、G31.9、G31.82)。此研究中,研究者使用了3年的时间窗,因此纳入了首次痴呆确诊前或后3年初始使用PPI的患者。排除了时间窗<6个月的配对,从而最小化潜在的原发性偏差。SR的计算方法为,初始PPI后首次诊断痴呆的患者数(因果组)除以初始PPI前首次诊断痴呆的患者数(非因果组)。校正了SR(aSR),从而避免了因时间推移,PPI使用和痴呆诊断的潜在趋势造成结果失真。研究者计算了aSR的95%置信区间(CIs)。对H2RA初始者重复了上述分析。使用1、2和6年时间窗和初始痴呆药物治疗进行了敏感性分析。

结果:结果显示,痴呆和PPI的aSR(7342对,aSR 1.21[95% CI,1.16~1.27])不高于痴呆和H2RA的aSR(6170对,aSR 1.91[1.80~2.02])。当使用各种时间窗和将结果限制于治疗痴呆的药物时,结果与主要结果一致。

结论:既往研究高估了PPI与痴呆风险之间的相关性。需要进一步的药物流行病学研究来鉴别与PPI使用相关的痴呆风险。

ICM:PPI vs. H2RA预防应激性溃疡

预防应激性溃疡(Stress ulcer prophylaxis,SUP)是ICU中常用的治疗措施。北美58家ICU发现质子泵抑制剂(PPI)是最常用的药物,其次是H2受体拮抗剂(H2RA);没有一家中心使用硫糖铝或抗酸药物。最近对欧洲、澳大利亚和加拿大97家中心的调查也得到了相似的结果。一项RCT研究的系统性综述发现与硫糖铝或不预防相比,H2RA降低胃肠道出血风险,未增加肺炎的风险;与H2RA相
