In this episode, Dr. Sarina Elmariah and Dr. Brian Kim explore prurigo nodularis (PN), with a focus on severe itch, fibrotic skin lesions, and their impact on patients’ quality of life. They discuss PN epidemiology, common comorbidities, and the challenges of managing multimorbid patients, while breaking down the neuroimmune mechanisms, highlighting the role of type 2 cytokines in itch and lesion development.

Join Lisa Swanson, MD, and Gina Mangin, MPAS, PA-C as they discuss the evaluation of the cytokine hierarchy in AD and the contributions of IL-4, IL-13, and IL-31 to itch.

In this soundbite video from the April 2025 ADVENT Forum in Lisbon, Portugal, Dr. Brian Kim explores the histaminergic and nonhistaminergic mechanisms of itch, highlighting how type 2 cytokines like IL-4 serve as central orchestrators of neuronal sensitization and immune–nervous system cross-talk.

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
Dr. Butler emphasizes the increasing prevalence of chronic itch in the aging population and details the significant physical, psychological, and healthcare system burdens it imposes. He also explores why chronic pruritus is often under-recognized and challenging to diagnose due to its multifactorial etiologies
This symposium highlights type 2 inflammation as a key driver of chronic itch and the characteristic skin lesions of prurigo nodularis and evaluates the real-world implications of targeted therapies on clinical practice.
In this soundbite video from the April 2025 ADVENT Forum in Lisbon, Portugal, Prof. Enno Schmidt highlights the role of type 2 cytokines involved in the dysregulated Type 2 immune responses that contribute to inflammation and subsequent itch in bullous pemphigoid.

Dr. Casale discusses delays in diagnosing CSU, the impact of severe itch on daily life and mental health, and the challenges in achieving remission.
Join leading experts Miguel Lanz, Lakshi Aldredge, Angela Bretton, and Hilary Ugras in an engaging case-based discussion that explores the interconnected nature of chronic underlying type 2 inflammation and its profound impact across multiple diseases.
