Abstract

The study aims to investigate nasal and lower airway inflammation in patients with non-allergic rhinitis (NAR), and to discuss a method of NAR classification based on inflammatory characteristics and its clinical significance. A total of 117 NAR patients admitted to our hospital from June 2010 to June 2011 were enrolled in this study, 162 healthy participants were employed as healthy controls. Nasal and lower airway inflammation were evaluated using the skin prick test, nasal and pulmonary visual analogue scale scoring, cell blood count, nasal douche, induced sputum assay, nasal provocation test, and bronchial provocation test. Compared to the healthy controls, NAR patients have significant higher levels of nasal douche eosinophils, more induced sputum eosinophils as well as blood eosinophils, and higher rates of nasal and bronchial provocation. Patient with high level of eosinophil in nasal douch tended to be with higher concentrations of eosinophils in induced sputum. Scores on the nasal and bronchial provocation tests are also correlated to each other. Among all NAR patients, 28 cases (23.9%) were with no abnormality detectable by eosinophil measurement or a provocation test, 39 cases (33.3%) were with elevated levels of eos...Continue Reading
