Overview
Brief Summary
This is a pilot study of inhaled antibiotic regimens is a pilot study examining clinical and laboratory endpoints of patients on inhaled antibiotic treatments. We hypothesize that alternation therapy utilizing Cayston and Tobi will inhibit antibiotic resistance and that alternation therapy will result in a decreased incidence of antibiotic resistance to Cystic Fibrosis (CF) microbial isolates. The long term strategic goal is to develop a model biometric system for selecting a patient's optimal inhaled antibiotic regimen by utilizing clinical and microbiological parameters.

Outcomes
Primary Outcomes
Antibiotic Resistance Profiles
Time Frame: Every three months within a 12 month period
The primary endpoint will be a change in the microbial resistance profile of pseudomonas aeruginosa (PA)isolates, change in PA sputum density, minimum inhibitory concentration of aztreonam and tobramycin for PA and the appearance or disappearance of other pathogens.
Secondary Outcomes
- Clinical Symptoms(Every 3 months within a 12 month period)
