| Outline of Final Research Achievements |
The purpose of this study was to evaluate the reversible airflow limitation, eosinophilic airway inflammation and neurogenic inflammation in adolescent asthmatics in remission. The results were compared with those in asthmatics with current medication. When comparing lung functions after bronchodilators, the percentage of subjects, whose % predicted values of FEV1.0 was still low, was significantly higher in subjects in remission, suggesting the presence of airway remodeling in these subjects. FENO, a marker of eosinophilic airway inflammation, was comparable between subjects in remission and with current medication. The measurement of plasma CGRP, a potent neuropeptide, was just started while we could not perform any statistical analysis during the study period.
