Bronchial challenge test (BCT) measures current airways-hyperreactivity, however, its predictive role in pre-school children (<6 years) for the diagnosis of asthma at school age is still debatable. We aimed to find whether preschool children with a positive adenosine or methacholine BCT are more prone to asthma at school age.

学龄前使用腺苷或乙酰甲胆碱进行支气管激发试验能否预测学龄期哮喘？

支气管激发试验 (BCT) 测量当前的气道高反应性，然而，其在学龄前儿童（<6 岁）中对学龄哮喘诊断的预测作用仍存在争议。我们旨在找出腺苷或乙酰甲胆碱 BCT 阳性的学龄前儿童是否更容易在学龄期患哮喘。
