摘 要 目的 探讨替格瑞洛与感染风险的因果关联。方法 采用两样本孟德尔随机化方法。基于迄今为止最大规模的替格瑞洛
及其主要活性代谢物AR-C124910XX体内暴露量的全基因组关联分析结果选取遗传工具变量。通过逆方差加权法孟德尔随机化
模型分析替格瑞洛及其主要活性代谢物AR-C124910XX与药物适应证(冠状动脉疾病、不稳定型心绞痛、心肌梗死、卒中和缺血性
卒中)的因果关系,作为遗传工具变量的阳性控制内容。进一步使用该方法分析替格瑞洛与细菌感染、急性下呼吸道感染、细菌性
肺炎、肺炎、急性上呼吸道感染、脓毒症的因果关系,并用异质性检验、水平基因多效性检验来评估结果的稳健性。结果 遗传代理
的替格瑞洛稳态药时曲线下面积(AUCss)增加可以显著降低冠状动脉疾病、心肌梗死、不稳定型心绞痛的发生风险(P<0.001),
而其主要活性代谢物AR-C124910XX的AUCss遗传工具变量未能通过阳性控制。进一步分析显示,遗传代理的替格瑞洛AUCss
的增加可以潜在地降低细菌感染[OR(95%CI)=0.80(0.65,0.99),P=0.040]和脓毒症[OR(95%CI)=0.84(0.73,0.98),P=0.023]的
发生风险。异质性检验结果表明,遗传代理的替格瑞洛AUCss与细菌感染、脓毒症的因果关联不存在异质性(P>0.05)。水平基
因多效性检验结果表明,遗传代理的替格瑞洛AUCss与细菌感染、脓毒症的因果关联不存在水平基因多效性的影响(P>0.05)。
结论 替格瑞洛具有潜在的降低脓毒症和细菌感染风险的作用。

ABSTRACT OBJECTIVE To investigate the causal association between ticagrelor and risk of infection METHODS Two-sample
Mendelian randomization was adopted. Genetic instrumental variables were selected based on the results of the largest genome-wide
association analysis to in vivo exposure of ticagrelor and its major active metabolite AR-C124910XX. The causal associations of
ticagrelor and its major active metabolite AR-C124910XX with drug indications (coronary artery disease, unstable angina pectoris,
myocardial infarction, stroke and ischemic stroke)were analyzed by inverse variance weighted Mendelian randomization model as a
positive control for genetic instrumental variables. The causal relationship between ticagrelor and bacterial infection, acute lower
respiratory infection, bacterial pneumoniae, pneumoniae,
