Objectives: To determine the effects of orally administered glutamine on the resting energy expenditure (REE) and nutritional status Of children and adolescents with sickle cell anemia. Methods: Twenty-seven children and adolescents (13 boys, 14 girls), 5.2 to 17.9 years old (median 11.0 years), received orally administered glutamine (600 mg/kg per day) for 24 weeks. Measures of REE and other nutritional parameters were compared at baseline and 24 weeks. Results: After 24 weeks, the patients' median REE (kcal/d) decreased by 6% (P = 0.053) as indicated by the Harris Benedict equations and by 5% (P = 0.049) as indicated by the modified equations. Patients with less than 90% ideal body weight had even greater declines in REE after 24 weeks (P < 0.03 and 0.02, respectively). Improvements in nutrition parameters and in two amino acids in the plasma were observed. Conclusions: After 24 weeks of orally administered glutamine, children and adolescents with sickle cell anemia had a decrease in REE and improvement in nutritional parameters. Those who were underweight had a greater decrease in REE than those of normal body weight. Lowering REE may be an effective way to improve the growth of these children and adolescents.
