- Background: Topical glucocorticosteroids are the first line therapy for airway inflammation. Modern compounds with higher efficacy have been developed, but head-to-head comparison studies are sparse. Objective: To compare the activity of two intranasal glucocorticoids, fluticasone furoate (FF) and mometasone furoate (MF) with respect to the inhibition of T helper (Th)1, Th2 and Th17 cytokine release in airway mucosa. Methods: We used an ex-vivo human nasal mucosal tissue model and employed pre-and post-Staphylococcus aureus enterotoxin BBackground: Topical glucocorticosteroids are the first line therapy for airway inflammation. Modern compounds with higher efficacy have been developed, but head-to-head comparison studies are sparse. Objective: To compare the activity of two intranasal glucocorticoids, fluticasone furoate (FF) and mometasone furoate (MF) with respect to the inhibition of T helper (Th)1, Th2 and Th17 cytokine release in airway mucosa. Methods: We used an ex-vivo human nasal mucosal tissue model and employed pre-and post-Staphylococcus aureus enterotoxin B (SEB)-challenge incubations with various time intervals and drug concentrations to mimic typical clinical situations of preventive or therapeutic use. Results: At a fixed concentration of 10(-10) M, FF had significantly higher suppressive effects on interferon (IFN)-gamma,interleukin (IL)-2 and IL-17 release, but not IL-5 or tumor necrosis factor (TNF)-alpha, vs. MF. While the maximal suppressive activity was maintained when FF was added before or after tissue stimulation, the cytokine suppression capacity of MF appeared to be compromised when SEB-induced cell activation preceded the addition of the drug. In a pre-challenge incubation setting with removal of excess drug concentrations, MF approached inhibition of IL-5 and TNF-alpha after 6 and 24 hours while FF maximally blocked the release of these cytokines right after pre-incubation. Furthermore, FF suppressed a wider range of T helper cytokines compared to MF. Conclusion: The study demonstrates the potential of our human mucosal model and shows marked differences in the ability to suppress the release of various cytokines in pre-and post-challenge settings between FF and MF mimicking typical clinical situations of preventive or therapeutic use.…
