Nutritional therapy in children with chronic renal failure

Area of Science:

• Pediatric Nephrology
• Nutritional Science
• Growth and Development

Background:

• Early childhood growth is critical, with retardation in the first two years significantly impacting final height.
• Children with uremia experience malnutrition and metabolic disturbances, leading to poor growth, particularly in prepubertal stages.
• Increased metabolic rate in uremia exacerbates nutritional challenges.

Purpose of the Study:

• To highlight the importance of dietary therapy for maximizing growth in young children with kidney disease.
• To discuss optimal energy and protein strategies for pediatric patients with uremia.
• To explore potential nutritional interventions like anabolic steroids, essential amino acid supplements, and ketoacids.

Main Methods:

• Review of nutritional requirements and challenges in pediatric uremia.
• Discussion of dietary modifications including energy, protein, fat, and amino acid intake.
• Exploration of adjunctive therapies such as anabolic steroids and ketoacids.

Main Results:

• Children's energy and protein needs are higher than adults', and may increase with uremia.
• Malnutrition and growth failure are severe in prepubertal children with uremia.
• Limited protein diets are challenging to implement without compromising energy intake.

Conclusions:

• Dietary therapy is essential for maximizing growth in children before dialysis or transplantation.
• Tailored diets high in energy and low in protein, supplemented with essential amino acids, may benefit infants.
• Further research into interventions like ketoacids could help balance adequate energy intake and reduce nitrogen toxicity.
