1 Fluticasone furoate nasal spray reduces the nasal-ocular reflex: A mechanism for the efficacy of topical steroids in controlling allergic eye symptoms  Fuad M. Baroody, MD, Deanna Shenaq, BSc, Marcy DeTineo, BSN, JiangHong Wang, MD, Robert M. Naclerio, MD  Journal of Allergy and Clinical Immunology  Volume 123, Issue 6, Pages (June 2009) DOI: /j.jaci Copyright © 2009 American Academy of Allergy, Asthma & Immunology Terms and Conditions

2 Fig 1 Study design. The timeline appears at the bottom. The 3 arrows labeled AG denote the 3 consecutive allergen challenges performed on 3 consecutive days while patients were still on intranasal treatment. During each of these challenges, the subjects were challenged with the diluent for the allergen extract, followed 10 minutes later by challenge with either ragweed or grass antigen extracts. All challenge solutions (diluent or allergen) were placed on the nasal septum by using filter paper discs.

3 Fig 2 The effect of FFNS on the sneezing response after allergen challenge. The x-axis shows the time scale and pretreatment. Net change from diluent is depicted as individual data (n = 20). The solid bars represent median levels. The dashed line represents the priming response. †P ≤ .03 vs day 1, illustrating priming, and ∗∗P < .01 and ∗P < .03 vs placebo, demonstrating the inhibitory effect of active treatment. FF, Fluticasone furoate nasal spray; PL, placebo.

4 Fig 3 The effect of FFNS on contralateral nasal secretion weights after allergen challenge. The x-axis shows the time scale and pretreatment. Net change from diluent is depicted as individual data (n = 20). The solid bars represent median levels. The dashed line represents the priming response. †P ≤ .04 vs day 1 and day 2, illustrating priming, and ∗P < .04 vs placebo, demonstrating the inhibitory effect of active treatment. FF, Fluticasone furoate nasal spray; PL, placebo.

5 Fig 4 The effect of FFNS on the total eye symptom score after allergen challenge. The x-axis shows the time scale and pretreatment. Net change from diluent is depicted as individual data (n = 20). The solid bars represent median levels. The dashed line represents the priming response. †P ≤ .04 vs day 1, illustrating priming, and ∗∗P ≤ .01 vs placebo, demonstrating the inhibitory effect of active treatment. FF, Fluticasone furoate nasal spray; PL, placebo.

6 Fig 5 The effect of FFNS on the percentage of eosinophils in nasal scrapings. The x-axis shows the time scale and pretreatment. Percent eosinophils in scrapings obtained at the beginning of each challenge are depicted as individual data (n = 20). The solid bars represent median levels. The dashed line represents the priming response. ∗∗P ≤ .01 and ∗P ≤ .05 vs placebo, demonstrating the inhibitory effect of active treatment. FF, Fluticasone furoate nasal spray; PL, placebo.
