NEJM:糠酸氟替卡松–维兰特罗治疗可降低COPD恶化率

慢性阻塞性肺疾病(COPD)的管理证据来自密切监测的疗效试验,这些试验中的患者都是在限制招募条件的基础上被选择参与研究的。因此有必要在更接近常规临床实践条件下进行随机试验。

慢性阻塞性肺疾病(COPD)的管理证据来自密切监测的疗效试验,这些试验中的患者都是在限制招募条件的基础上被选择出来参与研究的。因此有必要在更接近常规临床实践条件下进行随机试验。

研究人员在75个全科诊所进行了一项对照有效性试验,研究人员随机分配2799例COPD患者每日一次接受氟替卡松糠酸酯(剂量为100μg)和维兰特罗(剂量25μg)联合治疗(氟替卡松糠酸酯-维兰特罗组)或常规治疗(常规护理组)。主要结果是中度或重度病情恶化的患者比率(这些患者在试验前1年内病情发生过病情恶化),次要结果是需要初级护理接触率(需要全科医生,护士或其他健康护理人员进行护理)和二级护理接触率(住院,访问门诊,或访问急诊科),COPD初步试验治疗修饰,和病情恶化的患者比率(这些患者在试验前3年内发生过病情恶化),通过时间-事件分析进行评估。

与常规治疗相比,氟替卡松糠酸酯-维兰特罗组的中度或重度病情恶化的发生率降低显著8.4%(95%可信区间1.1至15.2)(P=0.02)。每年与COPD相关的初级和二级护理接触率在两组间无显著差异。在时间-事件分析中,在第一次中度或重度恶化的发生率没有显著组间差异。在氟替卡松糠酸酯-维兰特罗组中,没有发生除肺炎以外的严重不良事件。其它严重不良事件数量在这两个组中是相似的。

在具有COPD病情加重病史的患者中,与常规治疗相比,氟替卡松糠酸酯联合维兰特罗每天一次的治疗方案可降低病情恶化率,并且没有更大的严重不良事件风险。
