Sleep quality burden in chronic rhinosinusitis with nasal polyps and its modulation by dupilumab.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is associated with a substantial burden on patients' quality of life and impaired sleep quality. The most common CRSwNP endotype is characterized by type 2 inflammation, with enhanced production of interleukin (IL)-4, IL-5, and IL-13. Dupilumab is a monoclonal antibody against IL-4 receptor-α, which inhibits both IL-4 and IL-13 signaling, and was recently approved for treatment of CRSwNP.
