BACKGROUND: Staphylococcus aureus (S. aureus) may be related to more rapid progression of cystic fibrosis (CF) lung disease.
METHODS: In the AREST CF cohort study, children diagnosed with CF undergo annual bronchoscopies with bronchoalveolar lavage and ultra-low-dose, chest computed tomography (CT) up to 6-years-old. Spirometry was assessed 3-monthly from the age of 4years. Associations between de novo S. aureus acquisition before school age and CT and lung function at ages 5-7years were investigated. Models were adjusted for multiple markers of disease severity at baseline.
RESULTS: De novo S. aureus acquisition at 3-years-old (n/N=12/122) was associated with increased bronchiectasis score at age 5-6years. This association decreased but remained significant after adjustment for confounders. S. aureus at 3 was associated with significantly reduced FEF25-75 at age 5-7years, but not with FEV1-%-predicted.
CONCLUSION: De novo S. aureus acquisition at age 3 is associated with later bronchiectasis and FEF25-75 in children with CF.
