Effectiveness of Multicomponent Lipid Emulsion in Preterm Infants Requiring Parenteral Nutrition

Effectiveness of Multicomponent Lipid Emulsion in Preterm Infants Requiring Parenteral Nutrition: A Two-Center, Double-Blind Randomized Clinical Trial

The purpose of this study is to compare the effects of a multicomponent lipid emulsion containing 30% soybean oil, 30% medium-chain triglycerides, 25% olive oil, and 15% fish oil with a conventional pure soybean oil lipid emulsion on the incidence of neonatal cholestasis, infant growth, infant morbidity and the biochemical assessment of liver enzymes.

Intravenous lipid emulsions are the major sources of non-protein energy and provision of required essential fatty acids. The reference lipid emulsion, widely used for many years, is prepared from soybean oil, which is rich in omega 6 polyunsaturated fatty acids and phytosterols that contribute to hepatotoxicity and their metabolites result in pro-inflammatory eicosanoid production. Existing evidence strongly supports a pathogenetic role of inflammation and oxidative stress on parenteral nutrition associated liver disease. Subsequent development of lipid emulsions has focused on reducing the amount of soybean oil and replacing it with other oils.Moreover the omega 3 fatty acids from fish oil are metabolized to anti-inflammatory eicosanoids which can prevent inflammatory responses. A novel multicomponent lipid emulsion may prevent liver injury, improve growth and decrease morbidity in preterm infants.

multicomponent lipid emulsion composed of 30% soybean oil, 30% MCTs, 25% olive oil and 15% fish oil (SMOF lipid) was administered at a dose of 1gm/kg/day within 24 hours after birth; lipid dosage was increased by an increment of 0.5 gm/kg/day until the maximal dose of 3.5 gm/kg/day was reached.The macronutrients and micronutrients were provided using the same products in both groups.

pure soybean oil lipid emulsion(intralipid) was administered at a dose of 1gm/kg/day within 24 hours after birth; lipid dosage was increased by an increment of 0.5gm/kg/day until the maximal dose of 3.5gm/kg/day was reached.The macronutrients and micronutrients were provided using the same products in both groups.

Lipids were first administered at a dose of 1gm/kg/day within 24 hours after birth for both groups; lipid dosage was increased by an increment of 0.5 gm/kg/day until the maximal dose of 3.5 gm/kg/day was reached.
