Dr Sarina Elmariah highlights the clinical challenges in diagnosing inflammatory skin diseases, using prurigo nodularis as a case study. Drs Culton, Eichenfield, and Hawkes then join in to discuss additional challenges and complexities when diagnosing other skin diseases.

The March 2025 ADVENT symposium in Orlando, Florida brought together 4 dermatology experts to explore the evolving science of type 2 inflammation. Type 2 inflammation plays a central role in the pathophysiology of multiple dermatological diseases, driving chronic immune dysregulation that affects patients with atopic dermatitis (AD) prurigo nodularis (PN), chronic spontaneous urticaria (CSU) and bullous pemphigoid (BP). Understanding the mechanisms behind type 2 inflammation is key to advancing care and improving patient quality of life.
Dive into the complex pathophysiology of chronic spontaneous urticaria (CSU), where mast cell degranulation drives the hallmark signs and symptoms. This interactive infographic elucidates how key type 2 cytokines, specifically IL-4 and IL-13, contribute to mast cell activation, immune cell trafficking into the skin, and neuronal sensitization in CSU, which ultimately leads to the release of mediators like histamine that cause wheals, angioedema, and itch.
Explore the characteristics of COPD and asthma, focusing on their shared inflammatory mechanisms and key clinical differences.

In this highlight video from the October 2024 ADVENT symposium at EAPS in Vienna, Austria, Dr Christine Bangert discusses how type 2 inflammation contributes to epidermal barrier dysfunction and chronic itch in AD

In this highlight video from the September 2024 ADVENT symposium at EADV’s Annual Meeting in Amsterdam, the Netherlands, Dr. Stephan Weidinger discusses how type 2 inflammation contributes to epidermal barrier dysfunction, perivascular infiltration and plasma protein leakage, and chronic itch in AD.
Listen to the latest updates in type 2 inflammatory science and associated skin diseases, brought to you by leading dermatology experts in the field. ADVENT On Air podcasts feature scientific conversations that explore new research into the pathophysiology, clinical features, and disease burden for a range of dermatological diseases linked to type 2 inflammation, including atopic dermatitis (AD) and prurigo nodularis (PN).

Use this educational tool to explore the daily burden of loss of smell for patients with CRSwNP.

Dr. Chovatiya explains that PN is primarily a chronic itch disease with a complex pathophysiology involving neuronal changes, type 2 inflammation, and fibrotic skin processes, affecting patients' overall well-being.
