Abstract

including Chronic Eosinophilic Pneumonia (CEP), Eosinophilic Granulo-matosis with Polyangiitis (EGPA) and Allergic Bronchopulmo-nary Aspergillosis (ABPA) are uncommon conditions linked to asthma. Fungi are implicated in ABPA but the aetiology of other ELDs is unknown. No studies have yet described the fungal communities in CEP or EGPA. Objectives To determine the fungal biomass and characterise the fungal communities in the upper and lower airways of ELD patients.
