Unified Airway Disease

Unified airway disease describes the shared epidemiologic and pathophysiologic relationship among the chronic inflammatory diseases of the upper and lower airways including allergic rhinitis, chronic rhinosinusitis, asthma, and chronic otitis media. This concept proposes that these diseases are manifestations of a single inflammatory process and require an integrated diagnostic and therapeutic approach to achieve global disease control. Future directions to further establish this entity should focus on pathophysiology, diagnostic markers, flora microbes with particular emphasis on fungi, the role of type 3 inflammation, and targeted therapeutics including biologics, JAK inhibitors, and synthetic peptides.
