Asthma is a chronic inflammatory disorder of the respiratory tract. Asthma control is directly related to bronchial
inflammation control and therefore a major component in the treatment of asthma is the anti-inflammatory controller therapy.
FeNO (fractionated exhaled nitric oxide) is a non-invasive marker of atopy and bronchial inflammation and therefore might
be useful as objective marker of asthma control. The aim of this study was to assess the way the controller therapy influences
the correlation between FeNO value and asthma control in children. For this purpose a prospective study was initiated which
included asthmatic children with FeNO measurements and asthma control status assessment, recording also if the patient was
receiving or not controller therapy at the moment of the evaluation. Further, the correlation between FeNO value and asthma
control status was evaluated, individually for patients who received or not controller therapy. For each of these categories the
correlation was also evaluated according to atopy. The results indicate that in children FeNO is correlated with asthma
control only in atopic patients receiving controller therapy.
