Abstract

PURPOSE: The purpose of this study was to evaluate the effect of amino acid mixtures on incidence and severity of total parenteral nutrition associated-cholestasis(PNAC) in very low birth weight infants.
METHODS
Retrospective review of 63 very low birth weight infants(birth weight < or =1,500 g) who received total parenteral nutrition(TPN) in our neonatal intensive care unit from January 2000 to December 2004 was performed. Patients were divided into 2 groups : Group I(n=32, Jan 2000-Jun 2002) and Group II(n=31, Jul 2002-Dec 2004), where infants in Group II received taurine and glutamic acid-rich amino acid mixtures. PNAC was defined as serum direct bilirubin(DB) level greater than 2.0 mg/dL. The incidence and severity of PNAC were compared between these groups.
RESULTS
The incidence of PNAC was significantly lower in Group II than in Group I(21.9% vs 6.5%, P<0.148). Maximum and mean DB levels were also significantly lower in Group II(P<0.05).
CONCLUSION
The incidence and severity of PNAC in very low birth weight infants may be reduced with different composition of amino acid mixtures in TPN. Further prospective randomized controlled studies are needed to determine an ideal composition of acid mixtures to prevent the development of PNAC.
