呼出气一氧化氮与肺功能和过敏原检测的相关性分析

目的 探讨呼出气一氧化氮（FeNO）与支气管舒张试验、血中特异性IgE水平的相关性.方法 对我院298例疑似支气管哮喘（简称哮喘）患者的FeNO、支气管舒张试验、血中特异性IgE水平进行统计学分析.结果 298例患者中支气管舒张试验阳性组患者的FeNO值高于阴性组,艾蒿或螨虫组合阳性组的FeNO值高于对应的阴性组.FeNO升高与支气管舒张试验阳性密切相关.结论 FeNO在支气管舒张试验阳性和对艾蒿、螨虫组合阳性的患者中高表达,对哮喘的诊断有一定价值.

The relationship of exhaled nitric oxide,spirometry and the allergen test

Objective To investigate the relationship of exhaled nitric oxide （FeNO） test,bronchodilator test （BDT） and serum specific IgE test.Methods Retrospective analysis was performed on the results of FeNO,BDT and serum specific IgE test of 298 patients who had symptoms of asthma.Results The levels of FeNO were higher in patients with positive response to bronchodilator than those in patients with negative response to bronchodilator.Having IgE antibodies against mugwort or mite was related to higher FeNO.The level of FeNO affected the positive rate of BDT.Conclusions The patients who have positive BDT,IgE antibodies against mugwort or mite have high level of FeNO.It is helpful to diagnosis of asthma.
