Parenteral fat emulsions based on olive and soybean oils: a randomized clinical trial in preterm infants

Abstract

Objective: To evaluate in premature infants a new parenteral lipid emulsion based on olive and soybean oils (ratio 4:1), with less polyunsaturated fatty acids (PUFA) and more alpha-tocopherol than standard soybean oil emulsion.

Study design: Premature infants (gestational age, 28-<37 weeks) were randomized to receive one of the two emulsions within the first 72 hours of life. The triglyceride dose was increased to 2 g/kg/day within 3 days. Plasma phospholipid fatty acids, alpha-tocopherol/lipid ratio, and urinary malondialdehyde (MDA) excretion were determined at baseline and after 7 days.

Results: Of 45 recruited infants, 33 completed the study per protocol (15 soybean oil, 18 olive oil emulsion). At study end, groups did not differ in plasma phospholipid arachidonic acid, total n-6 and n-3 metabolites, but the olive oil group showed higher values of the PUFA intermediates C18:3n-6 (0.19% +/- 0.01% vs. 0.13% +/- 0.02%, P < 0.05) and C20:3n-6 (2.92% +/- 0.12% vs. 2.21% +/- 0.17%, P = 0.005). The plasma alpha-tocopherol/total lipd ratio was higher in the olive oil group (2.45 +/- 0.27 micromol/mmol vs. 1.90 +/- 0.08 micromol/mmol, P = 0.001), whereas urinary MDA excretion did not differ.

Conclusion: The lower PUFA supply with the olive/soybean oil emulsion appears to enhance linoleic acid conversion. The reduced PUFA content, combined with a higher antioxidant intake in the olive oil group, results in an improved vitamin E status. The olive oil-based emulsion is a valuable alternative for parenteral feeding of preterm infants who are often exposed to oxidative stress, while their antioxidative defense is weak.
