Clin Gastroenterol H:使用PPI会导致认知功能下降吗?

2018-05-23 王淳 环球医学

2018年5月,发表于《Clin Gastroenterol Hepatol》上的一项研究,表明了质子泵抑制剂(PPI)的使用和认知功能下降之间缺乏相关性。

2018年5月,发表于《Clin Gastroenterol Hepatol》上的一项研究,表明了质子泵抑制剂(PPI)的使用和认知功能下降之间缺乏相关性。

背景&目的:PPI使用和痴呆相关性的研究存在矛盾结果。研究者在丹麦一项中年和老年双胞胎研究中调查了PPIs对认知功能下降的作用。

方法:在一项前瞻性研究中,研究者收集了来自中年患者(46-67岁;丹麦中年双胞胎研究)和老年患者(丹麦老年双胞胎的纵向研究)的调查数据,患者在10年期间(中年研究,n=2346)或2年期间(老年纵向研究:n=2475)经历认知评估(5个组分的成套测试)。研究人员检测了研究开始前2年内和随访期内PPIs的累积使用剂量并计算出每日常规剂量(DDDs),使用的数据来自全国处方注册库。采用多变量线性回归模型考察累积PPI使用与基线时认知功能的综合评分和随访期内评分降低之间的相关性。

结果:中年研究中研究开始前PPIs的使用与稍微低的平均认知评分相关。在中年研究中高剂量PPIs使用者(≥400 DDD)的平均评分校正差值低于未使用者(高剂量PPI使用者平均总评分,43.4±13.1 vs未使用者的46.8±10.2;校正差值0.69分;95%CI,-4.98~3.61)。在老年双胞胎纵向研究中,高剂量PPI使用者同未使用者相比,具有较高的校正评分(高使用者的平均总评分,35.2±10.8 vs未使用者的36.2±11.1;校正差值0.95分;95%CI,-1.88~3.79)。在认知功能下降的分析中,老年纵向研究中的高剂量PPIs使用患者的基线评分和随访期评分之间校正平均差异低于未使用者(基线时高剂量PPI使用的平均总评分为36.6±10.1,随访期34.3±12.3 vs未使用者基线时38.1±10.5,随访期37.6±11.3;校正差值-1.22分;95%CI,-3.73~1.29)。在中年研究中,最高剂量PPIs使用者(≥1600 DDD)同未使用者相比,认知能力下降的程度略低(高剂量PPI使用的基线平均总评分,43.4±10.1和随访期平均总评分,41.3±9.7 vs未使用者基线评分,49.1±10.2和随访期评分46.3±9.9;校正差值0.94分;95%CI,-1.63~3.50)。PPI使用者和未使用者之间的评分没有明显差异。

结论:在丹麦2项大型基于人群的双胞胎研究的数据分析中,研究者发现PPI使用和认知功能下降之间无关。
