Our understanding of the pathogenesis of this disease has improved in recent years. The process is primarily driven by the Th2 pathway, but with significant contributions from the Th22 pathway, the Th1 and Th17 axes, epidermal barrier dysfunction, pruritus, and JAK/STAT signaling. Advances in our understanding of the pathogenesis of atopic dermatitis have led to the development of new systemic treatments. Of particular note are biologic agents targeting IL-4 and IL-13 (e. g., dupilumab, tralokinumab, and lebrikizumab) and small molecules, such as JAK inhibitors (e. g., baricitinib, upadacitinib, and abrocitinib). Novel topical treatments include phosphodiesterase 4 and JAK/STAT inhibitors. In this article, we review the main advances in the treatment of atopic dermatitis. Characterization of clinical and molecular phenotypes with a key pathogenic role is essential for driving these advances. ER -
