BACKGROUND
This study aimed to compare the effect of 2 lipid emulsions (LEs), a medium-chain triglyceride (MCT)/ω-3-polyunsaturated fatty acid (PUFA)-containing LE and a soybean-based LE, on the incidence of neonatal cholestasis, bronchopulmonary dysplasia (BPD), and lipid profile of preterm infants. Patients and
METHODS
In this prospective, observational study, 2 groups of preterm neonates, the very low birth weight (VLBW) (n = 129) and the low birth weight (LBW) groups (n = 153), which received parenteral LEs for at least 7 days, were included. Infants received either MCT/ω-3-PUFA-containing LE (SMOFlipid, subgroup I) or soybean-based LE (Intralipid, subgroup II) according to the attending neonatologist's preference and availability. Full biochemical assessment was performed on days of life 15, 30, and 45 and on discharge.
RESULTS
Of the VLBW infants, 7.4% and 13.3% of infants in subgroups I and II, respectively, developed cholestasis (P = .39; odds ratio [OR], 0.52; 95% confidence interval [CI], 0.15-1.76). The duration of LE administration was independently associated with cholestasis (P < .001; OR, 0.925; 95% CI, 0.888-0.963). The maximum amounts of lipids administered ranged between 1.6 and 3.6 g/kg/d in both VLBW subgroups. The VLBW subgroup I had lower incidence of BPD, lower alkaline phosphatase and phosphate, higher high-density lipoprotein (HDL), and lower cholesterol-to-HDL ratio on discharge than the VLBW subgroup II. The type of LE was independently associated with BPD and alkaline phosphatase. In the LBW group, the type of LE was not associated with clinical and biochemical parameters.
CONCLUSIONS
In VLBW infants, the MCT/ω-3-PUFA-containing LE administration is associated with decreased BPD and more favorable lipoprotein profile. Although a trend toward a lower incidence of cholestasis was observed, a preventive effect of MCT/ω-3-PUFA-containing LE on parenteral nutrition-associated cholestasis is not supported.
