阿托伐他汀减轻慢性支气管炎患者气道炎症反应的前瞻性观察研究
摘要
区人民医院医院呼吸内科门诊就诊,符合 XX 慢性支气管炎诊断标准的受试者,在签署知情同意书后被分为两组,对照组
接受常规治疗,试验组在常规治疗的基础上,每日口服阿托伐他汀 20 ㎎,两组均治疗 6 月。采用卡方检验比较两组受试者
治疗前后 LCQ(Leicester Cough Questionnare)的改善情况。当 p < 0.05 具有统计学意义。结果:共筛选 82 例受试者,其
中 22 例筛选失败,剩余 60 例(对照组及试验组各 30 例)接受 6 个月治疗及随访。试验组和对照组的 LCQ 平均变化分别
为 1.5 和 -0.7 个单位,平均变化的差值为 2.2(95% CI 0.5-3.9;p=0.01)。试验组和对照组受试者的 LCQ 增加至少 1.3 个
单位的比例分别为 40% 和 17%,两组相差 23%(95% CI 1-45;p=0.01)。试验组和对照组的不良事件发生率分别为 33% 和
10%,两组相差 23%(95% CI 31—43;p=0.02),无严重不良事件发生。结论:阿托伐他汀治疗 6 个月可以减轻慢性支气
管炎患者的咳嗽症状及气道炎症,但对于改善肺功能并无明显帮助。
