Converging paths toward unified therapeutic approaches in atopic dermatitis, vitiligo, and alopecia areata.

Abstract

Emerging evidence reveals significant epidemiologic, genetic, and immunologic connections between atopic dermatitis, vitiligo, and alopecia areata, challenging previously established notions of their distinct pathogenic and molecular signatures. Exploring these commonalities not only enhances our understanding of each disease's pathogenesis, but also supports the development of unified treatment strategies for these frequently co-occurring disorders. This review examines key immune players shared across the 3 conditions, including cytokines, immune cells, and signaling pathways. Building on these insights, we also evaluate a range of therapeutic options-ranging from treatments approved by the Food and Drug Administration to those currently in clinical trials-alongside proposed future therapeutic targets. This comprehensive approach aims to advance our management of these interconnected autoimmune and inflammatory disorders with greater precision.
