Résumé
PURPOSE: The efficacy of intranasal corticosteroids for the treatment of allergic rhinitis has been reported. But the efficacy of intranasal corticosteroids has not been compared between perennial nonallergic rhinitis (PNAR) and perennial allergic rhinitis (PAR). METHODS: Twenty-three patients with PNAR and 19 patients with PAR were enrolled in this study. Every patient received fluticasone propionate (FP) 200 g (100 g, bid) daily for 4weeks. Control group (n=16) was received only anti-histamine (hydroxyzine 0.6 mg/kg/dose) intermittently. Efficacy of FP was evaluated by the mean change in nasal congestion, rhinorrhea, nasal itching, sneezing and total nasal symptom score (a sum of patient ratings of nasal congestion, rhinorrhea, nasal itching, and sneezing). RESULTS: Both groups (PNAR and PAR) showed similar improvement of nasal symptom with FP 200 g compared with control. (P< 0.05) In the total population, both groups showed significant improvements from baseline in TNSS compared with control during each week of treatment. (P< 0.05) In PNAR and PAR, nasal congestion was significantly improved more than in control. (P< 0.01, P< 0.01) Rhinorrhea and itching in PAR were improved more than in control. (P=0.02, P=0.03) In sneezing, all three groups showed no differences. (P=1.00, P=0.31, P= 0.29) CONCLUSION: Intranasal FP is an effective treatment for perennial nonallergic rhinitis as same as perennial allergic rhinitis.
