Feeding the child with chronic liver disease

Area of Science:

• Pediatric Gastroenterology and Hepatology
• Nutritional Science
• Transplantation Medicine

Background:

• Protein energy malnutrition (PEM) is prevalent in 60% of children with chronic liver disease, leading to significant growth failure.
• Pretransplant malnutrition is a critical risk factor for morbidity and mortality following pediatric liver transplantation.
• Improved survival rates post-transplantation necessitate a focus on nutritional rehabilitation for optimal psychosocial development and quality of life.

Purpose of the Study:

• To highlight the critical role of nutritional status in pediatric liver disease and transplantation.
• To underscore the importance of anticipating and preventing malnutrition through early nutritional intervention.
• To review the pathophysiology of malnutrition in liver disease and emerging therapeutic strategies.

Main Methods:

• Serial anthropometric assessment for early detection of malnutrition.
• Nutritional support as a preventive strategy.
• Review of research on the pathophysiology of malnutrition, including fat, energy, and nitrogen metabolism.

Main Results:

• Malnutrition is an inevitable consequence of chronic liver disease in a majority of affected children.
• Nutritional status significantly impacts post-liver transplantation outcomes, including morbidity and mortality.
• Advances in understanding pathophysiology are leading to novel nutritional interventions.

Conclusions:

• A multidisciplinary approach involving pediatric dietitians, nurses, psychologists, and clinicians is essential for effective nutritional intervention.
• Early nutritional assessment and intervention are key to improving outcomes for children with chronic liver disease and those undergoing transplantation.
• Future strategies incorporating docosahexaenoic acid, branched-chain amino acids, and structured lipids show promise for nutritional rehabilitation.
