[Tolerance of two lipid emulsions used in parenterally-fed premature infants - a comparative study]

Area of Science:

• Neonatalogy
• Nutritional Science
• Biochemistry

Background:

• Parenteral nutrition (PN) is crucial for premature infants unable to tolerate enteral feeding.
• Lipid emulsions are a key component of PN for neonates.
• This study compares olive oil-based vs. soybean oil-based lipid emulsions in premature infants.

Purpose of the Study:

• To compare the effects of olive oil-based (ClinOleic) and soybean oil-based (Ivelip) lipid emulsions on plasma lipid concentrations.
• To evaluate the impact of these emulsions on hyperbilirubinemia, assessed by plasma bilirubin levels and phototherapy duration.
• To determine the safety and efficacy of different lipid emulsions in neonatal PN.

Main Methods:

• A double-blind, randomized study involving 44 premature infants (<32 weeks gestation, <1500g birth weight).
• Infants received either olive oil-based or soybean oil-based lipid emulsions within 48 hours of birth.
• Plasma lipid and bilirubin levels were measured on the 7th day of life.

Main Results:

• Both lipid emulsions were well tolerated and maintained normal plasma lipid concentrations.
• The olive oil group showed significantly higher plasma cholesterol and LDL concentrations compared to the soybean oil group.
• No significant differences were observed in plasma bilirubin levels or phototherapy times between the two groups.

Conclusions:

• Both olive oil-based and soybean oil-based lipid emulsions are safe and effective for parenteral nutrition in premature infants.
• These emulsions maintain normal plasma lipid concentrations without adversely affecting bilirubin levels.
• The choice between olive oil and soybean oil emulsions may warrant consideration regarding specific lipid profiles in neonates.
