Urticaria as a Systemic Disease

In this episode of the Global Allergy and Asthma Excellence Network UCARE Podcast on Urticaria, Prof. Torsten Zuberbier speaks with Prof. Marta Ferrer from Spain about an important question: Is chronic spontaneous urticaria (CSU) only a skin disease, or is it a systemic inflammatory condition? Together, they discuss emerging evidence showing that urticaria affects far more than the skin and how this should influence patient management.

They discuss: 🔹 Why is CSU increasingly considered a systemic inflammatory disease? 🔹 Which inflammatory biomarkers are linked to disease severity? 🔹 When should treatment be escalated beyond antihistamines? 🔹 How can biomarkers help personalize therapy? 🔹 Why are patient-reported outcomes and real-world data so important? 🔹 How do comorbidities influence treatment decisions?

The discussion highlights the importance of early disease control, individualized treatment strategies, and understanding that chronic urticaria often extends beyond wheals and itch alone.

Key Learnings from the Episode: Chronic spontaneous urticaria is more than a skin disease. Patients often experience fatigue, sleep disturbances, and systemic symptoms. Inflammatory biomarkers such as CRP, D-dimer, and serum amyloid A correlate with disease activity. If antihistamines fail within a few weeks, treatment escalation should be considered. Modern therapies should aim for complete disease control as early as possible. Patient comorbidities can help guide individualized treatment choices. Real-world data from registries and digital tools are improving understanding of CSU. Personalized treatment strategies are becoming increasingly important in urticaria care.
