摘要
气道高反应性(BHR)是哮喘的主要特征,组织胺支气管激发试验是测定气道反应性常用的方法。过敏性鼻炎、荨麻疹和支气管哮喘的发病都与I型变态反应有关。临床实践中已注意到哮喘与过敏性鼻炎迁延发作之间有相应的关系。我们对过敏性鼻炎。
Histamine bronchial provacation test was performed in 103 patients with allergic rhinitis and 87 patients with urticaria. 45 healthy persons served as control. Bronchial hyperresponsiveness (BHR) was defined as PD-20 FEVI<2.2mg. 37.8% of patients with allergic rhinitis and 11% of patients with urticaria revealed BHR. In contrast, none of the healthy persons had BHR. This study showed that the incidence of BHR correlated to th type of allergic rhinitis, patient's baseline FEVI/FVC values and past asthma, but did not correlated to sex, age and duration of the disease. The incidence of BHR in patients who were smokers was not higher than that in patients who were non-smokers. Since patients with allergic rhinitis or urticaria may be predisposed to develop BHR, we should give them more medical care.
