• Mepolizumab significantly reduced SNOT-22 and NPS scores in CRSwNP patients at 6 and 12 months, indicating improved quality of life and reduced polyp size.
• Olfactory function, as measured by the Sniffin' sticks test, showed a statistically significant increase at both 6 and 12 months following Mepolizumab treatment.
• All patients in the study continued Mepolizumab treatment at the 12-month follow-up due to reduced NPS, improved quality of life, and decreased need for systemic corticosteroids.
