Calorie and protein requirements of pediatric patients with acute nonlymphocytic leukemia
Insights
Pediatric leukemia patients require fewer calories than healthy children, but similar protein intake. Intravenous nutrition reduced oral intake, and infections worsened protein status in these patients.
Area of Science:
- Pediatric Oncology
- Nutritional Science
- Hematology
Background:
- Children with acute nonlymphocytic leukemia (ANLL) have unique nutritional needs.
- Accurate assessment of calorie and protein requirements is crucial for managing ANLL patients.
- Laminar air flow units are used for immunocompromised patients, potentially impacting nutritional intake.
Purpose of the Study:
- To determine the specific calorie and protein requirements for pediatric patients with ANLL.
- To compare these requirements with Recommended Dietary Allowances (RDA) for healthy children.
- To investigate the impact of intravenous nutrition and infection on nutritional status.
Main Methods:
- Studied 6 pediatric patients with ANLL in a laminar air flow unit.
- Estimated calorie and protein needs using anthropometric data.
- Monitored oral intake and assessed visceral protein status via serum albumin levels.
Main Results:
- Mean total caloric requirement was 136% of estimated basal metabolic rate, lower than healthy children's RDA.
- Mean protein requirement was 108% of RDA.
- Intravenous nutrient provision decreased oral intake; infections negatively affected serum albumin levels.
Conclusions:
- Pediatric ANLL patients have lower caloric needs than typically recommended for healthy children.
- Protein requirements are comparable to the RDA, but clinical factors like infection significantly impact nutritional status.
- Careful monitoring of oral intake and nutritional support is essential for ANLL patients, especially during infections.
Abstract:
The calorie and protein requirements wer studied in 6 pediatric patients with acute nonlymphocytic leukemia treated in a laminar air flow unit. Calorie and protein requirements were estimated from anthropometric data. Mean total caloric requirement for weight maintenance was 136% of estimated basal metabolic rate, which is much lower than the RDA for healthy children. The mean protein requirement was 108% RDA. Provision of intravenous nutrients depressed oral intake. Infection had a deleterious effect on visceral protein status as determined by serum albumin.
