Abstract

Background: The clinical effects of Aspergillus fumigatus in the cystic fibrosis (CF) airway, with the exception of allergic bronchopulmonary aspergillosis, is unclear. Methods: CF adolescents and adults (age 14 years and older) underwent bacterial and semi-selective fungal culture testing to determine the prevalence of fungi in the CF respiratory tract and the independent association between the presence of Aspergillus fumigatus and clinical characteristics. Results: Aspergillus fumigatus (10.3%) and Candida species (57.8%) were the most common filamentous fungi and yeast seen respectively in the sputa of 206 individuals with CF. Inhaled corticosteroid (ICS) use was more common in Aspergillus fumigatus-positive than Aspergillus fumigatusnegative (100% versus 75.8%, p = .01). Aspergillus fumigatus was significantly associated with lower respiratory domain score (β −8.74, 95% CI −16.6, −0.88, p = .03), representing worse respiratory-related quality of life, accounting for demographics, disease characteristics, and the presence of a pulmonary exacerbation. Conclusion: The presence of Aspergillus fumigatus in CF sputum was associated with worse respiratory quality of life in CF in a crosssectional, single center study. Longitudinal analysis examining the clinical implications of Aspergillus fumigatus on respiratory health over time is needed.
