Podcast on Cross-speciality Perspectives on Practical Management of Atopic Dermatitis-Associated Ocular Surface Diseases

There is a growing awareness among dermatology providers of ocular comorbidities in patients with the chronic inflammatory skin disease atopic dermatitis (AD). For example, the prevalence of ocular surface diseases (OSD) such as conjunctivitis is higher in patients with AD than in the general population, and the use of some AD treatments may be associated with OSD. In a recent review published in the Journal of the American Academy of Dermatology, dermatologists and ophthalmologists provided an overview of the different types, etiology, pathophysiology, and practical management of OSD associated with AD. This review included a suggested treatment algorithm that champions a partnership between dermatology providers and eye care providers for optimal screening, diagnosis, and care. In this podcast article, a dermatologist and ophthalmologist who were authors on this review are joined by a nurse practitioner moderator to discuss how these concepts can be adapted to clinical practice, inclusive of dermatologists, eye care providers, and relevant advanced practice providers. This podcast focuses on the authors' clinical experiences and highlights the key aspects of optimal care, including exploring additional questions to answer with future research.

Biomarkers in Atopic Dermatitis: A Review of the Role of IL-13 and the Impact of Tralokinumab Treatment

Atopic dermatitis (AD) is a chronic, inflammatory skin disease that can significantly affect quality of life. Presence, severity, and therapeutic response of AD are traditionally reported through clinical assessments including the Eczema Area and Severity Index or Investigator's Global Assessment. These clinical rating scales are visual assessments used in clinical trials to denotate AD severity. Alternatively, biomarkers open the potential to further enhance diagnosis of AD, assess disease status and severity, and potentially enable tailored treatment options for patients. Biomarkers can be classified according to their clinical use, clinical presentation, and underlying/endogenous molecular mechanisms. Specifically, interleukin (IL)-13, which has been shown to be a key biomarker in AD pathogenesis, can be used for prediction of AD development and to monitor clinical severity/response to treatment. Treatment with tralokinumab, a human monoclonal antibody that binds directly to-and subsequently blocks signaling of-IL-13, has been shown to reduce inflammation, re-balance the skin microbiome, and improve the skin barrier in patients with AD. In this review, key AD-related biomarkers, the role of IL-13 in driving AD pathogenesis, and the impact of IL-13 inhibition by tralokinumab on other AD-related biomarkers are discussed.
