    Abstract:
    BACKGROUND: The usefulness of early interventional treatment (EIT) with intranasal corticosteroids (INSs) compared with postonset treatment (POT) has not been clarified. OBJECTIVES: To study the efficacy and safety of EIT with INSs compared with POT and placebo in Japanese cedar/cypress pollinosis. METHODS: We designed a 3-armed, double-blinded, randomized, placebo-controlled trial. Patients received mometasone furoate nasal spray (EIT group: n = 25), placebo (n = 25), or 4 weeks of placebo followed by 8 weeks of mometasone (POT group: n = 25) for a 12-week period starting on February 1, 2011. The primary end point was the comparison of the total nasal symptom score (TNSS) among the 3 groups. Total ocular symptom score (TOSS), total naso-ocular symptom score (TSS), Allergic Rhinitis and Its Impact (ARIA) on Asthma classification, and safety were the main secondary end points. RESULTS: The placebo and POT groups, but not the EIT group, had a significant exacerbation of TNSS and TOSS soon after the start of pollen counts being high on consecutive days. The 12-week mean TSS in the EIT group (score, 2.3) was significantly lower than in the placebo (5.0; P < .01) and POT (3.9; P = .03) groups. All patients in the placebo and POT groups were classified as having persistent rhinitis, whereas 80% of the EIT group met the ARIA classification criteria (P = .03). The quality-of-life score and nasal eosinophil cationic protein levels were lower in the EIT and POT groups compared with the placebo group. Daytime sleepiness, smell disturbance, and the mean dose of loratadine taken as the rescue medication were similar. Treatment with mometasone was well tolerated. CONCLUSION: EIT with INSs is superior to POT in controlling pollinosis.
