目的探讨雾化诱导痰液嗜酸性粒细胞和外周血嗜酸性粒细胞计数对过敏性哮喘诊断价值。方法对34例过敏性哮喘患者和15例健康对照者进行超声雾化诱导引痰,并同时检测痰及外周血嗜酸性粒细胞计数。结果过敏性哮喘患者痰液嗜酸性粒细胞阳性率为67.2%,健康对照组阳性率为0.13%(P<0.01);过敏性哮喘患者外周血嗜酸性粒细胞阳性率为11.3%,健康对照组阳性率为0.07%(P<0.01)。结论诱导引痰嗜酸性粒细胞计数对过敏性哮喘具有重要诊断价值,并且较外周血嗜酸性粒细胞计数更为敏感,且易于检测,有利于推广应用。
Objective To investigate the diagnostic value of eosinophil and sputum eosinophil count in patients with allergic asthma. Methods 34 cases of allergic asthma and 15 healthy controls were induced by phlegm and phlegm, and sputum and peripheral blood eosinophil counts were also detected. Results The positive rate of sputum eosinophils in allergic asthma patients was 67.2%, the positive rate in healthy controls was 0.13% (P <0.01); the positive rate of peripheral eosinophils in allergic asthma patients was 11.3% The positive rate was 0.07% (P <0.01). Conclusion Induction of phlegm eosinophil count has important diagnostic value for allergic asthma, and more sensitive than the peripheral blood eosinophil count, and easy to detect, is conducive to the promotion and application.
