Olfactory Dysfunction in Chronic Rhinosinusitis with Nasal Polyps: Effect of Treatment with Emphasis on Biological Therapy.

Purpose Of Review: Olfactory dysfunction significantly impacts quality of life that affects a majority of the patients with chronic rhinosinusitis with nasal polyps (CRSwNP). The aim of this review is to explore the impact of various treatment regimens on olfactory dysfunction in patients diagnosed with CRSwNP.

Recent Findings: Accurate assessment of olfactory dysfunction remains challenging and should incorporate both psychophysical tests and patient-reported outcomes.

Two-year results of tapered dupilumab for CRSwNP demonstrates enduring efficacy established in the first 6 months.

Background: Dupilumab is an anti-T2-inflammatory biological registered for chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP), indicated by integrated CRS-care pathways when optimal medico-surgical treatment yields insufficient CRS control. This study aims to evaluate long-term results with focus on established therapeutic efficacy while tapering dupilumab.

Methods: Real-life, prospective observational cohort study in single tertiary referral center with add-on dupilumab as primary biological treatment in adult (≥18 years) biological-naïve CRSwNP patients per the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS)2020-indication with a 2-year follow-up.
