RESUMO
INTRODUCTION: Patients with cystic fibrosis (CF) present lower airway infection with Pseudomonas aeruginosa. Treatment of initial infection is fundamental to reduce subsequent damage. MATERIAL AND METHODS: We evaluated the efficacy of eradication treatment of P. aeruginosa in patients with CF from northeast Mexico using two protocols: inhaled colistin/oral ciprofloxacin and nebulized tobramycin 300 mg/oral ciprofloxacin. The intervention group included 17 patients with CF and recent infection with P. aeruginosa. The control group consisted of 23 chronically colonized patients of comparable age. RESULTS: Patients received 27 courses of eradication treatment. P. aeruginosa was eradicated in 21/27 (77.77%). The infection free period was 16.9, 11.7 months (colistin) and 17 ± 9.7 months (tobramycin) with no statistically significant difference (P = 0.97). CONCLUSIONS: Treated patients maintained normal lung function, better nutritional status, and a better chest X-ray score. In the control group 17/23 (73.9%) patients died with no deaths in the study group.
