[Energy balance in infants born from HIV seropositive mothers]
OBJECTIVES: A nutritional evaluation of infants born from HIV seropositive mothers was carried out during their follow up and diagnostic investigation. The energy balance (EB) of infected and noninfected children were compared. METHODS: The energy balance (intake energy, fecal energy, and resting energy expenditure) was prospectively determined by indirect calorimetry, considering 13 infants (6 girls and 7 boys) between 1 and 6 months of age, born from HIV positive mothers. This was made in two opportunities: before and after the diagnosis of the disease. A full nutritional assessment, including clinical examination and anthropometric measures (weight, height and skinfold thickness), was also determined in these two opportunities. After the definite diagnosis, the infants were finally assembled in 2 different groups: infected (5 in 13) and noninfected (8 in 13). The children were monthly submitted to clinical evaluations and orientation, during all the study. RESULTS: By analyzing the anthropometric measures of the two groups, it was observed that the infected group had malnutritional manifestations since the first evaluation. The resting energy expenditure (kcal/kg/dia) of the infected group was higher than that of the noninfected group: 64.5-/+16.8 vs 48.0-/+5.7 (p<0.05) at the first evaluation and 68.0-/+11.7 vs 51.8-/+3.1 (p<0.05) at the second, respectively. CONCLUSION: The higher resting energy expenditure of the children in the infected group might be the cause of the protein energy malnutrition during the asymptomatic phase when the diagnosis was uncertain.
