Chest:COPD患者服用阿司匹林与呼吸系统发病率的关系

2018-12-27 xing.T MedSci原创

由此可见,每日服用阿司匹林与COPD急性加重率降低、呼吸困难几率减少和生活质量提高有关。在服用阿司匹林的COPD患者进行的随机临床试验有必要考虑到未测量的和残留的混杂因素。

在Meta回归分析中,COPD患者服用阿司匹林可降低全因死亡率。然而,阿司匹林对COPD发病率的影响尚不清楚。

近日,呼吸领域权威杂志chest上发表了一篇研究文章,在基线时研究人员获得了患有COPD的SPIROMICS参与者(FEV1/FVC<70%)自我报告的每日阿司匹林使用量。COPD急性加重期(AECOPD)通过季度结构化电话问卷进行前瞻性确定,最长可达3年,并分为中度(需要使用抗生素或口服皮质类固醇治疗的症状)或严重(需要急诊或住院治疗)。根据倾向得分,阿司匹林服用者与非服用者一对一匹配。使用零膨胀阴性二项式模型研究阿司匹林使用与总的、中度和重度AECOPD之间的关联。线性或Logistic回归用于探究与基线呼吸症状、生活质量和运动耐量之间的关联。

在1698名参与者中,45%的参与者报告在基线时每日服用阿司匹林。倾向得分匹配有503个参与者配对。阿司匹林服用者AECOPD的总发生率较低(调整后的发病率比率[IRR]为0.78,95%置信区间[CI]为0.65-0.94),对中度但非严重的AECOPD效果相似(IRR为0.86,95%CI为0.63 -1.18)。服用阿司匹林与较低的总圣乔治呼吸问卷评分(β为-2.2,95%CI为-4.1至-0.4)、中度-重度呼吸困难几率降低(改良的医学研究委员会问卷评分≥2调整后的比值比为0.69,95%CI为0.51-0.93)和COPD评估评分(β为-1.1; 95%CI为-1.9至-0.2),但与6分钟步行距离无关(β为0.7米; 95%CI为-14.3至15.6)。

由此可见,每日服用阿司匹林与COPD急性加重率降低、呼吸困难几率减少和生活质量提高有关。在服用阿司匹林的COPD患者进行的随机临床试验有必要考虑到未测量的和残留的混杂因素。
