This study investigated nasal mucociliary clearance as related to nasal eosinophilia in nonallergic rhinitis patients using the technique of nasal saccharine challenge. Fifty-six consecutive patients with nonallergic rhinitis were evaluated with nasal cytology and saccharine challenge. A saccharine challenge time of greater than 25 minutes was considered abnormal. Twelve of 56 patients (21.4%) had nasal eosinophilia. Fifteen of 56 patients (26.8%) had prolonged nasal circulation times greater than 25 minutes, indicating delayed mucociliary clearance. Although 7 of 12 patients (58.3%) with nasal eosinophilia had delayed mucociliary clearance, only 8 of 44 patients (18.2%) without eosinophilia had circulation times longer than 25 minutes. The correlation of nasal eosinophilia with prolongation of the nasal circulation time is statistically significant (chi square 5.84, P = .0156). We postulate that damage to the nasal mucociliary system may be an etiologic factor for a subset of patients with nonallergic rhinitis and that this damage may be mediated by eosinophils.
