Not only asthma but also 29.5% to 76.5% of patients with non–cystic fibrosis bronchiectasis are sensitized to A fumigatus.4,5 Therefore, a broader term for allergic fungal airway disease has been proposed to encompass ABPA and other conditions with IgE sensitization to thermotolerant fungi and evidence of fungus-related lung damage,6,7 which highlights the importance of sensitization to thermotolerant fungi in the pathophysiology across airway diseases. This evidence concerns the gene IGHE and asthma.
