The European Respiratory Society (ERS) International Congress 2026 brought together emerging evidence across asthma, chronic cough, rhinitis, sleep-disordered breathing, airway inflammation, and corticosteroid safety. Highlights include findings on anti-IL-5 pathway therapy in severe eosinophilic asthma, IL-37 and airway remodelling, macrophage ferroptosis and tissue-resident memory T cells, the clinical relevance of mucus plugs in chronic cough, rhinitis and obstructive sleep apnea in children, allergen desensitization in asthma, and corticosteroid exposure-associated adverse events .

1-7 Emerging mechanistic evidence in refractory chronic cough also explores the role of ATP-induced laryngeal hypersensitivity and its potential implications for therapeutic strategies. 8 Explore the ERS Highlights & Insights 2026 for a concise overview of selected Congress findings and their potential…
