Professor Matthias Augustin highlights the role of type 2 inflammation in chronic itch across distinct pruritic skin diseases and the cumulative burden of chronic itch and skin lesions in PN.
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.
This symposium delves into the pivotal role of type 2 inflammation in diverse skin conditions, including atopic dermatitis, prurigo nodularis, chronic spontaneous urticaria, and bullous pemphigoid. It highlights both shared and distinct disease mechanisms and patient burdens, providing crucial insights for optimizing clinical management strategies through a series of engaging panel discussions with Drs Eichenfield, Elmariah, Culton, and Hawkes.
Professor Matthias Augustin emphaizes that prurigo nodularis is a chronic systemic disease with a significant and multifaceted burden, encompassing both visible skin manifestations and hidden psychosocial and physical comorbidities.
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.
