Insights
Neonates with lower gestational age, birth weight, or small for gestational age status receiving mixed lipid emulsion (MLE) show higher triglyceride levels. Monitoring is crucial for these high-risk infants.
Area of Science:
- Neonatalogy
- Clinical Nutrition
- Pediatric Critical Care
Background:
- Mixed lipid emulsion (MLE), often soybean, medium chain triglycerides, olive, and fish oils (SMOF), is increasingly used in neonatal intensive care units.
- Limited data exists on triglyceride (TG) trajectories in neonates receiving MLE.
- This study investigates TG levels in neonates on MLE, stratified by gestational age (GA), birth weight (BW), and growth restriction.
Purpose of the Study:
- To compare triglyceride (TG) levels in neonates receiving mixed lipid emulsion (MLE).
- To stratify neonates by gestational age (GA), birth weight (BW), and small for gestational age (SGA) status.
- To identify predictors of hypertriglyceridemia in neonates on MLE.
Main Methods:
- Included neonates born at <32 weeks GA or with BW <1500 gm.
- Measured plasma TG levels 24 hours after initiating SMOF at 2 gm/kg/day and 3 gm/kg/day.
- Compared TG levels across groups based on GA (<28 vs. ≥28 weeks), BW (<1000 vs. ≥1000 gm), and SGA status.
Main Results:
- Analyzed data from 427 infants (2018-2021).
- Significantly higher TG levels observed in neonates with GA <28 weeks, BW <1000 grams, and SGA.
- SGA and BW were independent predictors of hypertriglyceridemia after SMOF initiation.
Conclusions:
- Emphasizes TG monitoring for neonates with GA <28 weeks, BW <1000 grams, and SGA.
- Suggests individualized TG monitoring for infants with GA >28 weeks, BW >1000 grams, and non-SGA status.
- Recommends larger prospective studies to validate findings on MLE and TG levels.
Background:
Mixed lipid emulsion (MLE), most commonly soybean, medium chain triglycerides, olive, and fish oils (SMOF), has replaced soybean-based lipid emulsions in many neonatal intensive care units. Only a few studies report the triglyceride (TG) trajectory in neonates receiving MLE. We designed a study to compare TG levels in neonates receiving MLE stratified by gestational age (GA), birth weight (BW), and growth restriction status.
Methods:
We included neonates born at <32 weeks GA or with BW <1500 gm. SMOF is started on admission, and plasma TG levels are measured 24 hours after 2 gm/kg/day and 24 hours after 3 gm/kg/day. TG levels were compared across groups defined by GA (<28 weeks vs. 328 weeks), BW (<1000 gm vs. 31000 gm), and small for GA (SGA) vs. appropriate plus large for GA groups using the Wilcoxon rank sum test.
Results:
From 2018 to 2021, 427 infants met the inclusion criteria. TG levels were significantly higher in neonates with GA <28 weeks, BW <1000 grams, and SGA with a notable broad distribution of TG levels. Logistic regression analysis confirmed SGA and BW as significant independent predictors of hypertriglyceridemia after SMOF at 2 gm/kg/day and 3 gm/kg/day, respectively.
Conclusions:
The study emphasizes the importance of TG monitoring for neonates with GA <28 weeks, BW <1000 grams, and SGA. Conversely, it is advisable to individualize TG monitoring for infants with GA>28 weeks, BW>1000 grams, and non-SGA status. Prospective studies with larger sample sizes are warranted to validate our findings.
