RESUMEN
The objectives of this study were to evaluate the nutritional status and the efficiency of high density oral supplements in patients with cystic fibrosis. Twenty patients with cystic fibrosis (10 boys and 10 girls) with a mean age of 11.63 years (SD:6.3) were studied. Sixty percent of these patients were receiving high density oral supplements. A clinical and nutritional evaluation, including a three day evaluation of food intake, were performed. Patients were separated into two groups according to oral supplement intake and the presence or not of pulmonary colonization. We found the patients to have a mild to moderate clinical status. Anthropometric values were lower than ideal. Intake of calories, macronutrients and micronutrients were similar (except for folic acid) in both groups of patients and were close or above the established dietetic recommendations for cystic fibrosis. Patients with pulmonary colonization scored lower in the Shwachman and Brasfield tests, had lower weights, subscapular skinfolds and nutritional indices, and higher plasma immunoglobulin A concentrations. We conclude that a free hypercaloric diet allows cystic fibrosis patients to maintain an adequate nutritional status. Oral supplements should be prescribed on an individual basis according to the results of periodic food records and clinical and anthropometric status evaluation.
