Progressive cholestasis and abnormal elevations of liver enzymes occurred in one third of 92, mostly preterm, newborn infants who received total parenteral nutrition (TPN) with Protein hydrolysates, synthetic L-amino acids, and intravenous fat emulsion. The synthetic amino acid plus intravenous fat emulsion was not superior to the protein hydrolysate in preventing liver disease. The liver function returned to normal after discontinuation of TPN, which suggests a causal relationship. Hepatic microscopy was abnormal in 12 of 14 infants examined. The main features were progressive cholestasis and portal tract fibrosis and infiltration, which led to liver failure and death in two infants. In our experience, liver disease is the major matabolic complication of TPN in infants.
