Scientific title
Multiple combination bactericidal antibiotics testing for acute exacerbations of cystic fibrosis associated with multi-resistant Burkholderia cepacia and Pseudomonas aeruginosa infection: a randomised controlled trial
Acronym
Study hypothesis
The objective of this clinical trial is to prospectively assess whether the use of combination antibiotic therapy, directed by results from multiple combination, bactericidal antibiotic testing (MCBT), improves bacteriologic and clinical outcomes in patients with acute pulmonary exacerbations of cystic fibrosis who are infected with multiple resistant bacteria.
Ethics approval
Approval gained from the Ottawa Hospital Research Ethics Board in Spring 2000

Condition
Pulmonary exacerbation in adult patients with cystic fibrosis (CF)
Intervention
Patients randomised to the control group will receive a 14 days course of any two intravenous antibiotics ± one inhaled antibiotic (tobramycin/TOBI) chosen by their physicians based on usual culture and sensitivity testing.
Patients randomised to MCBT-directed therapy group will receive a 14 days course of any two intravenous antibiotics ± one inhaled antibiotic (tobramycin/TOBI) chosen based on MCBT culture and sensitivity testing.

Primary outcome measure
The time (days) from randomisation until the patient's next pulmonary exacerbation.
Secondary outcome measures
1. Mean changes in sputum bacterial densities for day zero to day 14
2. Changes in pulmonary function, pre-bronchodilator forced expiratory volume in one second (FEV1), and forced vital capacity (FVC)
3. Changes in oxygenation from day zero to day 14
4. The proportion of antibiotic treatment failures in both treatment groups within 14 days
5. Changes in subjective dyspnoea score from day zero to day 14
6. Length of hospital stay, for patients admitted to hospital
7. Adverse effects related to antibiotic therapy
