摘要
目的 探讨支气管激发试验在咳嗽变异性哮喘诊断中的作用。方法 2 34例以慢性咳嗽为主要表现疑诊咳嗽变异性哮喘患者 ,吸入磷酸组织胺做支气管激发试验 ,检测其气道高反应性。结果 全部 2 34例患者中支气管激发试验阳性 134例 ,阳性率 5 7 3% ,其中男性 6 7例 ,女性 6 7例。气道高反应性程度分布 :极轻度 5 1例 ,占 38 1% ;轻度 5 3例 ,占 39 5 % ;中度 19例 ,占 14 2 % ;重度 11例 ,占 8 2 %。结论 对以慢性咳嗽为主要表现 ,经常规抗生素和止咳治疗效果差的患者及时进行支气管激发试验 ,有助于明确诊断。
Objective To evaluate the role of bronchial provocation test in diagnosing cough variant asthma (CVA). Methods A total of 234 subjects (120 males, 114 females) were studied. They were clinically suspective of CVA(chronic cough for at least 3 weeks, exclusive of lung disease) without apparent reduction in lung functions (baseline FEV_1≥70% prediction). Bronchial provocation test with histamine was applied to assess the bronchial reactivity. Results The positive rate of bronchial provocation test was 57.3%. And slight, mild, moderate and severe BHR accounted for 38.1%, 39.5%, 14.2%, and 8.2% respectively. Conclusion Bronchial provocation test is useful in diagnosing patients with chronic cough.
