ABSTRACT

Introduction: Chronic infection with Pseudomonas aeruginosa (P. aeruginosa) is associated with a greater deterioration of pulmonary function, increase in hospitalizations and shorter survival in patients with cystic fibrosis.
Objectives: To evaluate the age of first detection of P. aeruginosa, effectiveness of the eradication treatment and prevalence of other pathogens in airway cultures.
Materials and Methods: A cohort of patients with CF diagnosed within first year of life, who had follow-up at University Hospital was studied. Respiratory cultures were obtained quarterly. Patients with infection by P. aeruginosa received eradication treatment.
Results: Thirty-five patients were included. During follow-up, 608 cultures were performed. In 34.7%, normal flora was detected, S. aureus 32.8%, P. aeruginosa 20.4%. Median age at first positive culture was 9 months. Eradication was achieved in 81.8%.
Conclusions: In this cohort of patients with cystic fibrosis, the acquisition of P. aeruginosa is earlier than in other groups reported in literature.
