Study Phase: Other
Recruitment Status: Recruiting Completed
Study Drug(s): Not Applicable
Number of Participants Being Recruited: 60
Single / Multi-Center: Single Center
Individuals with CF suffer from intermittent exacerbations of their disease, which is characterized by increased symptoms and drop in lung function. It is not clear that an individual who presents with mildly increased symptoms or a small drop in lung function should be treated with antibiotics nor how long antibiotics should be given when patients are treated for an exacerbation. This trial will measure biomarkers in blood, sputum, and exhaled breath at baseline and during the course of an exacerbation to to determine if biomarkers can be used to identify individuals who would benefit from initiation of antibiotic therapy as well as benefit from prolonged courses of antibiotics.
