Dr. Butler explores how type 2 inflammation is a common underlying mechanism in several prevalent chronic pruritic skin conditions affecting the elderly, such as CPUO, AD, BP, and PN
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.
Professor Matthias Augustin details the various clinical manifestations of prurigo nodularis, illustrating how different lesion types can present concurrently in patients.
Professor Sarina Elmariah highlights the multifaceted role of IL-4 and IL-13 in driving dermal fibrosis in prurigo nodularis, which leads to persistent scarring and dyspigmentation that significantly contribute to patients' embarrassment, anxiety, depression, and self-esteem.
Professor Matthias Augustin highlights the high prevalence of both atopic and non-atopic comorbidities in patients with PN, including increased risks of cardiovascular events and all-cause mortality.

Welcome to the AD learning hub focused on key scientific education on atopic dermatitis, featuring ADVENT resources.
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.
