Bronchial hyperreactivity (BHR) has been observed in respiratory disorders other than asthma but asthmatics usually show BHR to differing degrees. The presence and degree of BHR in asthma was evaluated and compared with that in other respiratory disorders. High BHR was observed in asthma (84%, with no difference between atopics and non-atopics), recurrent or persistent cough (36%), laryngeal spasm (50%), Kartagener's syndrome (66%) and cystic fibrosis. BHR was low in patients with allergic rhinitis but no asthma and was absent in patients with unexplained dyspnoea (100%) and in healthy controls (91%).
除哮喘外，在其他呼吸系统疾病中也观察到支气管高反应性（BHR），但哮喘患者通常表现出不同程度的BHR。评估了哮喘中BHR的存在情况和程度，并与其他呼吸系统疾病中的情况进行了比较。在哮喘（84%，特应性和非特应性之间无差异）、反复或持续性咳嗽（36%）、喉痉挛（50%）、卡塔格内综合征（66%）和囊性纤维化中观察到高BHR。变应性鼻炎但无哮喘的患者BHR较低，不明原因呼吸困难患者（100%）和健康对照者（91%）中未发现BHR。
