Description

<p>Objective:We examined the effects of SLIT with tablets containing JCP antigens on nasal symptoms and sleep disturbance in patients with Japanese cedar pollinosis during pollen dispersal season. Methods:A total of 128 patients with Japanese cedar pollinosis were categorized into four groups:19 one-year SLIT with tablets group, 16 two-year SLIT with drops group, 19 antihistamine group, and 74 untreated group. The scores of nasal symptoms and sleep disturbance were evaluated based on the Japanese guidelines for allergic rhinitis and the Athens Insomnia Scale. Results:The scores of nasal symptoms and sleep disturbance at the peak cedar pollen period in the two-year SLIT with drop group and the one-year SLIT with tablets group were significantly lower than those in untreated group. Additionally, these scores were significantly lower in the one-year SLIT with tablets group than those in the antihistamine group. Conclusion:It is suggested that SLIT with JCP tablets improved both nasal symptoms and sleep disturbances at peak pollen period in patients with Japanese cedar pollinosis. SLIT with JCP tablets for one year was more effective than SLIT with JCP drops for two years and prophylactic treatment with antihistamines. J. Med. Invest. 69 : 97-100, February, 2022</p>
