Abstract
Background. Nowadays, the measure of the fractional concentration of exhaled nitric oxide (FeNO) enables to assess airway inflammation during an office visit and there is international consensus on this testing methodology. The aim of this study was to evaluate whether FeNO measurement is predictable for bronchial hyperreactivity (BHR) in children with allergic rhinitis, asthma, or both. Methods. Two hundred and eighty children with allergic rhinitis, allergic asthma, or both were evaluated. Bronchial function (FEV1 and FEF 25-75), BHR (assessed by methacholine challenge), FeNO, and sensitizations were assessed. Results. Bronchial function, BHR, and FeNO were significantly different in the three groups (p
