PURPOSE: Fractional exhaled nitric oxide (FeNO) is an noninvasive biomark of airway eosinophilic inflammation and well tolerant. Patients with allergic rhinitis (AR) who had eosinophilic inflammation in the lower airway might show elevated FeNO value. Whether FeNO can reflect the lower airway eosinophilic inflammation in patients with non-allergic rhinitis (NAR) or not remained unclear. Our study aims to investigate the significance of FeNO in detecting the eosinophilic inflammation in lower airway of nonasthmatic patients with NAR.
