Insights
Most pediatric acute liver failure (PALF) patients have adequate nutrition at liver transplant (LT). However, some worsen during hospitalization, highlighting the need for early nutrition therapy (NT) post-LT for better outcomes.
Area of Science:
- Pediatric Hepatology
- Clinical Nutrition
- Transplantation Medicine
Background:
- Pediatric acute liver failure (PALF) is a critical condition characterized by rapid liver function decline in children.
- Liver transplantation (LT) is a life-saving intervention for PALF patients.
- Understanding nutritional status is crucial for managing PALF and optimizing post-LT outcomes.
Purpose of the Study:
- To assess clinical and nutritional status of PALF patients at admission and during hospitalization before LT.
- To investigate the relationship between nutritional status and clinical outcomes in PALF patients undergoing LT.
- To identify critical periods for nutritional intervention in pediatric liver failure.
Main Methods:
- Prospective study of pediatric patients undergoing LT for PALF.
- Serial nutrition assessments including z-score body mass index-for-age and z-arm circumference-for-age (zAC/A).
- Evaluation of clinical outcomes and their correlation with nutritional parameters like serum albumin and C-reactive protein.
Main Results:
- Majority of PALF patients (82.6%) presented adequate nutritional status at admission based on BMI and zAC/A.
- Nearly half (47.6%) experienced a decline in nutritional status during hospitalization, indicated by decreased zAC.
- No statistically significant association was found between initial nutritional status and clinical outcomes.
Conclusions:
- While many PALF patients are well-nourished at LT, a significant portion experiences nutritional decline during hospitalization.
- Post-LT hospitalization represents a high-risk period for nutritional deterioration.
- Early and proactive nutrition therapy (NT) is essential for improving outcomes in pediatric liver failure patients.
Background:
Pediatric acute liver failure (PALF) is a clinical diagnosis in which previously asymptomatic children exhibit a rapid loss of liver function.
Objectives:
To describe the clinical and nutrition conditions at admission and during hospitalization in patients with PALF who underwent liver transplantation (LT) at a referral center and establish a possible association between nutrition status and prognosis in this population.
Methods:
A prospective study was conducted on children underwent LT because of PALF. Nutrition assessment was performed at admission and repeated weekly until hospital discharge, and their relationships with clinical outcomes were tested.
Results:
The study population consisted of 23 patients with a median age of 60 months and, in most cases, the etiology of acute liver failure (ALF) was indeterminate (69.6%). The majority of the patients were well nourished according to the z score body mass index-for-age (82.6%) and z arm circumference-for-age (zAC/A) (82.6%). A decline in nutrition status was observed in 47.6% of the patients, as indicated by a decrease in zAC. Clinical and nutrition improvement was demonstrated by the progressive increase in zAC, serum albumin levels, and phase angle (PA) values and by the reduction in C-reactive protein levels. There was no statistically significant relationship between nutrition status and clinical outcomes.
Conclusion:
Most children and adolescents with ALF presented adequate nutrition status at the time of LT, and some patients worsened their nutrition status during hospitalization, suggesting that post-LT is a period of high nutrition risk, and early nutrition therapy (NT) must be a priority in these patients.
