RESUMO

The aim of this preliminary study was to determine specific proteins, related to inflammation process and nutritional status as well as to total antioxidant capacity, in children suffering from cystic fibrosis (CF). The study was performed on 17 nonhospitalized children (12 boys and 5 girls) with CF aged 3 months to 10 years, who were assisted at the Nutrition Service from Pedro de Elizalde Hospital. Transferrin, transthyretin, ceruloplasmin (Cp), haptoglobin, C-reactive protein (CRP) and fibrinogen were measured by single radial immunodiffusion techniques. Total antioxidant capacity (TAC) was determined by a decolorization assay. Statistical analyses were performed by the Student's t test. Transferrin and transthyretin values were lower in CF patients in comparison with data obtained from healthy children (reference group, RG). The decreased transferrin concentration and the tendency towards low plasma transthyretin values suggested an abnormal nutritional status. However, higher Cp and haptoglobin levels were shown in patients than in RG. The fact that 23 and 50% of patients exceeded the desirable values for fibrinogen (<285.0 mg/dl) and CRP (<0.2 mg/dl), respectively, should be highlighted. The TAC (mM; Trolox equivalents) was shown to be lower in the CF group than in RG. The diminished TAC concomitant with an increased plasma Cp concentration would exacerbate the inflammatory status and could explain the depression of the immune system. These preliminary results could explain the need to include biochemical and functional parameters in the early nutritional status evaluation in CF patients in order to use appropriate nutritional and pharmacological therapies and consequently to improve their survival and quality of life.

RESUMO

El objetivo del trabajo es evaluar el estado nutricional con respecto a hierro en un grupo de niños con diferentes patologías, al ingreso en terapia intensiva, a través de la determinación de hematocrito, concentración de hemoglobina, protoporfirinas eritrocitarias libres y analizar los niveles de fracciones séricas específicas: transferrina, proteína C reactiva y ceruloplasmina. En treinta y un pacientes (entre tres y cuarenta y ocho meses de edad) internados en la Unidad de Cuidados Intensivos Pediátricos con diferentes patologías, se determina hematocrito (Hto), la concentración de hemoglobina (g/dL) (Hb) por colorimetría, FEP por método Piomelli expresándose los resultados como FEP/Hto y FEP/Hb y transferrina, ceruloplasmina y preoteína C reactiva sérica (mg/dL) por inmunodifusión radial cuantitativa sobre placas...
