Early detection of lung function abnormalities in young children with cystic fibrosis

Abstract

The onset of lung disease in cystic fibrosis (CF) begins early in life with respiratory infection, inflammation, and structural lung damage all reported in infants with CF in the first months of life. As new treatments become available, it is essential that we have outcome measures that can be used to track disease progression and treatment efficacy. In this review, we have examined the role of lung function testing in infants and preschool children with CF. In particular, we have focused on the ability of the various lung function tests to detect the presence of respiratory pathogens and structural lung disease, increased inflammation, and the onset of acute exacerbations
