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.
