Nutritional Considerations in the Child With Liver Disease
Nutritional management of the infant and child
with liver disease is highly dependent upon the type of liver
disease. Acute liver disease, such as that secondary to viral
hepatitis, requires no specific nutritional therapy with the
exception that branched-chain amino acid supplements may be
indicated in the management of hepatic encephalopathy. Nutritional
management of the child with chronic liver disease depends upon
whether or not cholestasis is present, since in that condition,
large amounts of fat-soluble Vitamin supplements and medium-chain
triglycerides are usually required for optimum growth. However,
anicteric cirrhotic liver disease also presents nutritional
challenges because of hypermetabolism, enteropathy, and increased
protein oxidation. Certain inborn errors of metabolism that result
in liver disease (including galactosemia, hepatorenal tyrosinemia,
hereditary fructose intolerance, and Wilson's disease) have
specific nutritional requirements. And, finally, the advent of
pediatric liver transplantation has placed new emphasis on the
importance of optimum nutritional management of the child with
chronic liver disease, since improvement of nutritional status in
the pretransplant period maximizes success of the transplant. This
review will focus on the pathogenesis of malnutrition in childhood
liver disease and will provide recommendations for nutritional
assessment and monitoring as well as nutritional management of
cholestatic liver disease, anicteric cirrhotic liver disease, and
the inborn errors of metabolism enumerated above. Specific
recommendations for nutritional management of the child awaiting
liver transplantation will be provided. (C) Elsevier Science Inc.
