摘      要：Background: Primary care physicians in Japan see many patients in a given day;consequently, they find it challenging to devote sufficient time for detailed clinical consultation and evaluation of asthma control status. The aim of this study was to investigate asthma symptoms that reveal the presence of inadequately controlled asthma. Methods: A pooled analysis of baseline data from 100 patients with asthma treated with inhaled corticosteroid(s) (ICS) alone or ICS/long-acting beta-agonist who participated in three previous clinical trials was performed. Asthma control status and asthmatic symptoms were determined using a five-item Asthma Control Questionnaire, and whether asthmatic symptoms reflect clinical markers was investigated. Results: Nocturnal awakening owing to asthmatic symptoms was observed only in the uncontrolled asthma group. Patient-reported wheezing was not observed in the group with well-controlled asthma, but was observed in all patients in the uncontrolled asthma group. Virtually all patients, irrespective of asthma control status, reported symptoms in the morning, limitation of normal daily activities, and shortness of breath. Conclusions: The presence of nocturnal awakening due to asthma and wheezing likely reflected uncontrolled asthma. These results will lead to re-recognition that clinical interview, querying nocturnal awakening from asthma and wheezing is a simple and useful approach to assess asthma control status in a primary care setting.
