慢性支气管炎(CB)的特点是有痰咳嗽,粘液分泌过多,导致生活质量受损,病情加重的风险增加。支气管流变术使用支气管内导管将非热脉冲电场应用于呼吸道。临床前研究表明,上皮消融后会有正常化的上皮细胞再生。近日,研究人员评估了支气管流变术在CB患者中的可行性、安全性和初始结果,研究结果已发表于Am J Respir Crit Care Med。

研究人员对两个独立的研究进行汇总分析,其中有30名患者接受了双侧支气管流变手术。随访6个月(主要结果)和12个月,包括评估不良事件、气道组织学,以及使用慢性阻塞性肺病(COPD)评估测试和圣乔治呼吸问卷(SGRQ)的症状变化。

 

研究共纳入30名患者(63%为男性;平均[SD]年龄,67[7.4];平均[SD]支气管扩张后FEV1,65%[21%];平均[SD]COPD评估测试得分25.6[7.1];平均[SD]SGRQ得分,59.6[15.3]),都进行了支气管流变术。6个月内没有发生与设备相关的严重不良事件,4个与手术相关的严重不良事件,此后12个月内也没有发生。6个月内最常见的非严重、与设备和/或手术相关的事件是:47%(14/30)的患者出现轻度咯血。从组织学上看,平均小球细胞增生的分数在统计学上有明显的减少(P < 0.001)。从基线到6个月,观察到COPD评估测试(平均,-7.9;中位数,-8.0;P = 0.0002)和SGRQ(平均,-14.6;中位数,-7.2;P = 0.0002)得分的明显变化,到12个月也观察到类似的结果。

综上,该研究为支气管流变术在有症状的CB患者中的可行性、安全性和初始结果提供了第一个临床证据。
