- Brief Summary
This is a prospective, randomized multi-center trial investigating the impact of lower airway infection with P. aeruginosa in COPD patients. The aim of the study is to evaluate if targeted antibiotic therapy against P. aeruginosa can improve the prognosis in patients with COPD. non-CF bronchiectasis (BE) and asthma.
- Detailed Description
P. aeruginosa represents a potentially significant cause of acute exacerbation of chronic pulmonary diseases and is possibly associated with significant morbidity and mortality. Despite this, the role of P. aeruginosa in the course of COPD, non-CF BE and asthma is less well characterized, and evidence based guidelines for management and treatment of the bacteria are lacking.
P. aeruginosa is more likely to be isolated from patients with more advanced disease and severely impaired lung function. It is, however, difficult to draw definitive conclusions regarding the extent to which the bacteria contributes to adverse clinical outcomes since severely reduced lung function by itself is a strong predictor of mortality in patients with chronic pulmonary disease. Infection with P. aeruginosa might therefore be secondary to damaged lung tissue and decreased lung function, and thereby have no independent impact on the prognosis
So far, and to the investigators best knowledge, no randomized controlled trial has been conducted to investigate whether specific antibiotic treatment of P. aeruginosa can reduce the risk of new exacerbations and improve the long-term prognosis in patients with COPD, non-CF BE and asthma.
In Denmark, the first choice of treatment for P. aeruginosa is usually a 10-14 day therapy of intravenous combination treatment of P. aeruginosa active antibiotics (piperacillin/tazobactam and ciprofloxacin).
The aim of the study is to investigate whether the intervention with targeted pseudomonas active antibiotics can reduce the loss of lung function, reduce the frequency of exacerbations and mortality.
