Abstract

BACKGROUND:

Increased patient longevity and aggressive antibiotic treatment are thought to impact on the microbial composition of the airways of adults with cystic fibrosis (CF). In this study, we sought to determine if a temporal change in the airway microbiology of adults with CF has occurred over time.

METHODS:

Longitudinal analysis of sputum microbiology results was undertaken on patients attending a large adult CF centre. Clinical status and health outcomes of transitioning patients were also assessed.

RESULTS:

A decrease in the prevalence of Pseudomonas aeruginosa, Staphylococcus aureus, Burkholderia cepacia complex and Aspergillus spp. (p=0.001, p<0.001, p=0.002 and p<0.001, respectively) occurred. Improvements in lung function among transitioning patients infected with P. aeruginosa were observed.

CONCLUSION:

Overtime, a decline in the prevalence of many CF airway pathogens has occurred. Significantly, an incremental improvement in lung function was reported for transitioning patients with current P. aeruginosa infections.
