Abstract:

目的探讨哮喘-慢阻肺重叠综合征患者的临床特征。方法采用基于医疗信息数据库的回顾性队列研究方法,调取接受治疗随访1年以上,固定气流受限患者信息,按照哮喘、慢阻肺,以及新版2014年哮喘-慢阻肺重叠综合征(asthmaandchronicobstructivepulmonarydiseaseoverlapsyndrome,ACOS)联合指南的标准形成三组患者队列,统计队列中ACOS患者的比例、年龄分布;分析比较患者末次随访的气道炎症细胞、肺功能及年化FEV1下降率等临床特征。结果240例初诊特征符合研究标准的患者被纳入分析,按新指南标准分组发现ACOS患者比例为29.17%,以40岁以上年龄患者为主(88.57%),男性患者(61.40%)略多于女性患者,78.58%的患者支气管舒张后第1秒用力肺活量占预计值的比例(postFEV1%pre)在50%以上,其性别组成、中位年龄、肺功能、气道嗜酸性粒细胞炎症患者比例与哮喘患者和慢阻肺患者比较,差异有统计学意义(P<0.05),具体数值介于哮喘患者和慢阻肺患者之间。未来风险评估提示虽然ACOS患者年化FEV1下降率与哮喘、慢阻肺患者差异无统计学意义(P>0.05),但下降的绝对值最大;而且中、重度年化急性加重的发生率也与慢阻肺患者相似,显著高于哮喘患者(P<0.01)。结论ACOS患者的临床特征介于哮喘、慢阻肺之间,而其未来风险更接近于慢阻肺。
