PURPOSE OF REVIEW: Aeroallergens are well established triggers of allergic rhinitis and asthma, yet their contribution to allergic skin diseases such as atopic dermatitis (AD) and chronic urticaria (CU) remains incompletely understood. This article reviews the molecular basis of aeroallergen-driven skin disease in AD and CU as well as management strategies.
RECENT FINDINGS: Aeroallergen triggered skin disease involves epithelial barrier disruption, innate immune activation, and neuroimmune amplification. Allergen disruption of the epithelial barrier through PAR-2 and TLR-mediated signaling, induces alarmins that sustain an IL-31-driven itch-scratch cycle. Biologics targeting these pathways reshape these cytokine networks, while checkpoint inhibitors show promise for durable remission. In CU, house dust mite sensitization correlates with basophil hyperreactivity and greater disease severity. Aeroallergen triggered inflammation involves overlapping barrier dysfunction, innate immune activation, and neuroimmune pathways that extend beyond traditional IgE-mediated allergic responses. Future research should prioritize endotype-based patient stratification and quantify the impact of aeroallergen exposure on chronic skin disease trajectory.
