Chronic airways infection with Pseudomonas aeruginosa (PA) is associated with increased frequency of exacerbations, deterioration in quality of life and increased mortality in adult patients with bronchiectasis. Current guidelines suggest the prescription of an eradication antibiotic treatment for a first episode of PA infection (early PA infection). Several antibiotic regimens may be proposed, ranging from a monotherapy with oral fluoroquinolone (FQ) to an intravenous cotherapy with the addition of inhaled antibiotics that seems to improve the rate of PA eradication. As no study strictly favoured one regimen, current practices are heterogeneous and could certainly benefit from stronger evidence, with both medical and economic impact.
≥18 years of age
Diagnosis of bronchiectasis on thoracic CT-scan
Recent isolation of P. aeruginosa (PA) in a respiratory sample (spontaneous or induced sputum or other lower respiratory tract sample obtained by bronchoscopy) within the last 3 months, with a PA positive respiratory sample obtained ≤ 3 weeks before randomization
Patient either Pseudomonas naive (i.e., never previously isolated PA) or Pseudomonas free (i.e., infection-free for ≥1 year, proven by at least two PA negative respiratory sample during the last year)
Confirmed diagnosis of cystic fibrosis
Pregnancy or breastfeeding
Women of childbearing potential (after the first menstrual period and until menopause or permanent sterility (hysterectomy, bilateral salpingectomy and bilateral oophorectomy)) who refuse to use effective contraception (hormonal or mechanical) for 3 months and/or to undergo pregnancy tests at baseline, 1 month and 3 months after baseline.
Isolation of PA in a respiratory specimen (spontaneous or induced sputum or other lower respiratory tract specimen obtained by bronchoscopy) more than 3 months to 12 months prior to randomization.
