Abstract | BACKGROUND: METHODS: Subjects with perennial allergic rhinitis were randomized 1:1 to q.d., open-label treatment with FFNS, 110 μg, or MFNS, 200 μg, for 1 year. These groups and a healthy control group that did not receive study medication underwent nasal biopsies at baseline and 12 months. RESULTS: The nasal biopsy population comprised 96 participants (37 using FFNS, 42 using MFNS, and 17 healthy controls). Epithelial thickness did not change appreciably from baseline to week 52 in any of the groups and mean change from baseline did not differ between FFNS and MFNS (least square mean difference, -0.001 mm, 95% confidence interval, -0.007, 0.006). Although not tested for significance, improvements over baseline were observed in epithelial histology in the FFNS group with more epithelium including intact columnar and ciliated epithelial cells. No appreciable change in the percentage of goblet cells was established. FFNS and MFNS were associated with decreases in epithelial and subepithelial nasal mucosal eosinophils and basophils from baseline to week 52. The percentage of subjects with no inflammatory cells at week 52 was 49 and 33% for eosinophils and 46 and 24% for basophils, for FFNS and MFNS, respectively. CONCLUSION: Yearlong therapy with either FFNS or MFNS showed no changes in epithelial thickness or the percentage of goblet cells as well as a reduction in inflammatory cell infiltrate. FFNS was associated with improvements in epithelial histology. These data support the long-term safety of FFNS in subjects with perennial allergic rhinitis.
