Abstract

Allergic rhinitis and asthma are closely associated. Inflammation is a common pathological characteristic shared by both disorders. The measure of the fractional concentration of exhaled nitric oxide (FeNO) may be considered a surrogate marker for airway inflammation. Forced expiratory flow between 25% and 75% of vital capacity (FEF25-75) has been previously demonstrated to be able to predict BHR and bronchial reversibility. The aim of this study was to evaluate whether impaired FEF25-75 values may be related to FeNO values in a pediatric cohort of allergic subjects. 850 children with allergic rhinitis, allergic asthma, or both, were evaluated. Bronchial function (FEV 1, FVC, and FEF25-75), FeNO, and sensitizations were assessed. Bronchial function and FeNO were significantly different in the 3 groups (p1 was found in patients with rhinitis, asthma and asthma with rhinitis (r=-0.72, r=-0.70 and r=-0.70, respectively). Impaired FEF 25-75 values (such as 25-75 is strongly and inversely related with FeNO and FEF25-75 may predict high FeNO levels in children with allergic rhinitis, asthma or both.
