Join Profs. Sachio Takeno and Joaquim Mullol for an educational symposium highlighting the multifaceted burden associated with loss of smell and congestion in patients with uncontrolled CRSwNP.

Learn how loss of smell in CRSwNP is a key symptom for both patients and providers.
Use this educational tool to explore the daily burden of loss of smell for patients with CRSwNP.
In this video soundbite from the ERS-ISIAN 2025 symposium, Dr. Vibeke Backer discusses how Type 2 inflammation drives severe, uncontrolled CRSwNP. It covers key immune cells and biomarkers (e.g., IL-4, IL-5, IL-13, TSLP), global prevalence differences, and the importance of symptom tracking and targeted therapies.
Explore a video, podcast, and interactive infographic to examine underlying type 2 inflammation and the enhanced disease burden in patients with CRSwNP and coexisting asthma, to understand key factors that may predict polyp recurrence, and to explore the value of systematic symptom assessment.
Experts from different specialties use a case-based discussion to understand type 2 inflammatory diseases from a nurse practitioner perspective.

Embark on this interactive triathlon challenge to uncover the interplay of type 2 inflammation, barrier dysfunction, and neuroimmune dysregulation in the disease pathology of CRSwNP.

Prof. Wytske Fokkens examines what is known and what else should be explored to understand the mechanisms of anosmia in patients with CRSwNP.

Prof. Claus Bachert describes how type 2 inflammation drives CRSwNP.
