Dr. Hawkes highlights how Chronic Urticaria is a mast cell centric disease with moderate levels of spontaneous remission in patients.

Dr Hawkes provides an overview of the distinctive characteristics of wheals and angioedema in clinical manifestation

Join Dr. Hawkes as he discusses what burdens and challenges CSU patients might expect and help identify that there are immune functions responsible for their symptoms not an external cause.

Join Dr. Kwatra outlining the micro itch cycle involving type 2 cell polarization and cytokines that directly affect fibroblasts to cause more immune dysregulation in PN.
The pathophysiology of chronic spontaneous urticaria (CSU) is complex and involves mast cell degranulation and elements of type 2 inflammation. Learn more about the role of mast cells, basophils, and type 2 inflammatory cells and cytokines involved in the pathophysiology of CSU.
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.
