Prior studies suggest that patients undergoing hematopoietic stem cell transplantation (HSCT) for malignancy have nutritional needs that are greater than their estimated needs. To determine whether energy estimation equations accurately predict energy expenditure of pediatric patients undergoing HSCT, we prospectively compared the estimated energy expenditure (EEE) and measured energy expenditure (MEE) of 40 patients at four time-points. We also investigated whether energy requirements changed during the transplant period. MEE was determined by indirect calorimetry. Data from 34 patients (autologous HSCT = 10, allogeneic HSCT = 24) were sufficient for analysis. The World Health Organization equation adequately approximated MEE only on day 14 after HSCT. At all other time-points, measured energy expenditure was significantly less than estimated energy expenditure obtained by using the WHO equation (applicable to all patients), the Seashore equation (for patients <15 years of age; n = 19), or the Harris-Benedict equation (for patients ≥ 15 years of age; n = 15). The median measured energy expenditure varied significantly over the study period and was greatest on day 14 after HSCT. Until accurate equations have been identified for estimating these patients' needs, the use of indirect calorimetry may be medically warranted.
