OBJECTIVE: Intranasal corticosteroids are effective for allergic rhinitis and broadly used in daily clinical practice. Systemic oral corticosteroids are also known to be effective for treatment of allergic rhinitis. These topical and systemic corticosteroids are both effective formulations for allergic rhinitis, and both drugs have some side effects. When treatment formulations for allergic rhinitis are selected based on side effects, topical corticosteroids are more commonly selected than systemic steroids. Systemic corticosteroids, on the other hand, have traditionally been believed to have higher and more instantaneous therapeutic effects than those of topical corticosteroids. However, there have been few reports of direct comparisons between topical corticosteroid and systemic corticosteroid efficacy. The purpose of this study was to evaluate the subjective outcomes of nasal symptom management using topical intranasal corticosteroid therapy or systemic oral corticosteroid therapy in patients with seasonal allergic rhinitis. We compared the efficacy of mometasone furoate nasal spray (MFNS) to betamethasone oral tablets (BOT) for the treatment of patients with seasonal allergic rhinitis. METHODS: In an open label study, patients with seasonal allergic rhinitis who had intermediate-to-severe symptoms and who visited the hospital without prior treatment were allocated to 1 of 3 treatment groups (noncorticosteroid group, topical corticosteroid group, and oral corticosteroid group). Evaluation was conducted using allergy diaries that consisted of patient questionnaires. The Japanese Rhinoconjunctivitis Quality of Life Questionnaire (JRQLQ) was used in this study. RESULTS: Compared to only loratazine nonsteroid therapy, both MFNS 200μg once daily and BOT 0.25mg twice daily significantly reduced the total and individual symptom scores for sneezing, nasal obstruction, watery nasal discharge, and nasal itching (P<0.05). Scores for itching of the eyes were reduced slightly more in the MFNS group than in the noncorticosteriod treatment group, but the difference was not significant. CONCLUSION: MFNS and BOT have virtually equivalent effects on nasal symptoms in patients with seasonal allergies. Our study was the first direct comparison between an intranasal corticosteroid spray and a systemic oral corticosteroid for seasonal allergic rhinitis. No significant differences were found in the therapeutic effects of the topical and systemic corticosteroids tested, suggesting that topical corticosteroids are expected to sufficiently improve nasal symptoms without administration of oral corticosteroids. Treatment with intranasal corticosteroid spray is more strongly recommended than treatment with systemic corticoid steroids, due to the side effects associated with each treatment.
