摘要 目的探讨支气管哮喘患者呼出气一氧化氮水平(FeNO)与血IgE、肺功能中第1秒用力呼气量占预计值百分比(FEV1%)水平及相关性。方法选取70例支气管哮喘患者(34例为急性发作期、36例为缓解期)、30例正常对照者分别测定FeNO、外周血清总IgE及FEV1%水平进行统计学分析。结果 70例确诊支气管哮喘患者的FeNO、血IgE和FEV1%水平分别与30例正常对照者比较,差异有统计学意义(P<0.05);哮喘缓解期患者FeNO、血IgE较急性期患者显著下降,FEV1%回升,但哮喘缓解期患者与正常对照者比较,FeNO及血IgE差异仍有统计学意义(P<0.05),FEV1%差异无统计学意义(P>0.05);哮喘患者FeNO水平与血IgE含量呈正相关(r=0.648、P<0.05),而与FEV1%呈负相关(r=-0.436、P<0.05)。结论哮喘患者FeNO及血IgE水平均显著升高,且两者变化呈正相关,FeNO及血IgE含量变化与哮喘患者病情严重程度密切相关,动态检测可为临床提供有意义的参考指标。而FEV1%仅于哮喘急性发作期明显变化,在缓解期与健康人无特异改变,说明FEV1%不能作为气道炎症程度的评价。
