Management of Neonatal Liver Failure

Introduction to Neonatal Liver Failure

The American Association for the Study of Liver Diseases recommends liver transplantation as the only effective treatment for neonatal liver failure when supportive or disease-specific therapies fail, and urgent evaluation at a pediatric liver transplant center should be initiated immediately upon diagnosis 1, 2

Immediate contact with a pediatric liver transplant center is mandatory for neonates presenting with acute liver failure or acute decompensation of established liver disease, as stated by the American Association for the Study of Liver Diseases 2
Obtain fractionated bilirubin, complete blood count, liver function tests, and prothrombin time/INR to evaluate synthetic function, as recommended by the American Academy of Pediatrics 3, 4
Measure alpha-fetoprotein levels, as elevated or rising values may indicate hepatocellular carcinoma risk, according to the American Association for the Study of Liver Diseases 2

Neonatal hemochromatosis is the leading cause of liver failure in neonates, with infants typically presenting within the first few days of life, and liver transplantation is the only effective treatment, as stated by the American Association for the Study of Liver Diseases 5, 1
Tyrosinemia Type 1 presents with systemic illness and liver dysfunction in infants, and treatment with dietary restriction of tyrosine and phenylalanine plus NTBC is recommended, according to the American College of Medical Genetics 5, 1
Urea cycle defects present with catastrophic illness, and urgent referral for liver transplantation should be considered to prevent irreversible neurological damage, as recommended by the Society for Inherited Metabolic Disorders 6
Crigler-Najjar Type I presents with marked unconjugated hyperbilirubinemia, and referral for liver transplant evaluation should occur at the time of diagnosis, according to the American Academy of Pediatrics 6, 7

Address hypermetabolism, which increases caloric requirements by 20-80% above normal in chronic liver disease, as recommended by the American Society for Parenteral and Enteral Nutrition 3
Monitor for failure to thrive and poor weight gain despite adequate caloric intake, according to the American Academy of Pediatrics 2, 3

Indications for urgent transplant evaluation include neonatal hemochromatosis with severe liver failure, Crigler-Najjar Type I, severe urea cycle defects, and tyrosinemia with HCC or incomplete response to NTBC and dietary management, as stated by the American Association for the Study of Liver Diseases 5, 1, 6, 7
The evaluation requires a comprehensive multidisciplinary team, including a hepatologist, transplant surgeon, and transplant coordinator, according to the American Society of Transplant Surgeons 2
Preoperative assessment must identify extrahepatic complications that may compromise survival and quality of life after transplantation, as recommended by the American Society of Transplantation 1
