Research Abstract |
Fractional exhaled nitric oxide (FeNO) levels of asthmatic children have been reported not to decrease even in remission. We wanted to know the FeNO levels in adolescent asthmatic subjects in remission by dividing them whether they had airway obstruction or not. The degree of their airway obstruction was divided into stable type, reversible peripheral airway obstruction type and reversible total airway obstruction type according to the results of airway reversibility test. As a result, mean values of FeNO levels in these subjects were high irrespective of their lung function patterns, and there was no significant difference among groups. The levels were not different from those in asthmatics without remission. These results suggested that airway inflammation, irrespective of the presence of airway obstruction or not, persisted in many adolescent asthmatic subjects in remission.
