Understanding Atopic Dermatitis in East Asian Populations

Understanding Atopic Dermatitis in East Asian Populations

Alvin Sherman Library

Atopic dermatitis (AD) is a chronic inflammatory skin disorder driven by disrupted skin barriers and immune dysregulation. While much research has explored its mechanisms, most studies focus on generalized populations, overlooking critical ethnic differences. East Asian individuals, for example, experience a particularly high prevalence of AD, linked to unique genetic and immunologic patterns. Common FLG mutations in East Asians include R501X and c.3321delA; however, certain ethnic subgroups carry other variants, such as K4022X, S3296X, and S2889X, demonstrating how different mutations contribute to a range of atopic dermatitis severity. Immune analyses further reveal heightened Th17 and Th2 activation, elevated IgE levels, and clinical features that sometimes resemble psoriasis, collectively defining the "Asian AD phenotype." Emerging evidence also suggests that AD in East Asian populations may increase susceptibility to other conditions, including osteoporosis, highlighting the need to consider systemic health alongside dermatologic care. Despite these findings, few studies explore personalized treatment strategies that account for both ethnicity and comorbidities. This presentation synthesizes current literature to highlight these population-specific patterns and advocates for precision-based approaches. By tailoring diagnosis and therapy to the unique genetic, immune, and systemic profiles of patients, clinicians can improve outcomes and reduce disparities in dermatologic care. Ultimately, this work emphasizes that understanding ethnic differences and comorbidities is not just a scientific pursuit but is essential for delivering equitable, effective care for patients living with atopic dermatitis.
