[Study of lung involvement in patients with cystic fibrosis]
OBJECTIVE: To characterize the involvement of the respiratory apparatus of patients with cystic fibrosis in order to obtain a comprehensive view of their pulmonary picture.METHODS: Data were obtained retrospectively from the medical records of 16 patients with cystic fibrosis; arterial gas and spirometry data were obtained prospectively for the same patients, who were not in an acute pulmonary situation. The patients were subjects of both sexes aged 6 years or older who were followed up at the Pediatrics Outpatient Clinic of the University Hospital, Faculty of Medicine of Ribeirão Preto, USP.RESULTS: Median patient age was 114 months (9 years and 6 months) ranging between 72 - 360 months, and 68.75% were males. Productive cough was the most frequent symptom observed in 75% of the population studied. All patients had positive sputum culture obtained at least one year before, with Pseudomonas aeruginosa being detected in 81.25% of the cases. Arterial gases revealed some abnormalities in 81.25% of the patients and spirometry revealed abnormalities in 56.25%.CONCLUSION: All patients presented at least one type of pulmonary alteration. Measurement of arterial gases detected a larger number of patients with altered pulmonary function than did spirometry, but the two examinations complemented each other for a good evaluation of pulmonary function.
