OBJECTIVE: During the early weeks of life optimization of nutrition in extremely preterm infants presents a critical opportunity to attenuate the adverse neurological consequences of prematurity and potentially improve neurodevelopmental outcome. We hypothesized that the use of multicomponent lipid emulsion (MLE) in parenteral nutrition (PN) would be related to larger volume of the cerebellum on brain magnetic resonance at term of equivalent age (TEA) in extremely low birth weight (ELBW) infants.
STUDY DESIGN: We analyzed the brain magnetic resonance imaging (MRI) at TEA of a cohort of preterm infants with gestational age ≤28 weeks and/or birth weight <1,000 g randomly assigned in our previous trial to receive an MLE or soybean-based lipid emulsion (SLE). The primary outcome of the study was the cerebellar volume (CeV), valued on MRI acquired at TEA. Secondary outcomes included total brain volume (TBV), supratentorial volume, brainstem volume, and CeV corrected for TBV evaluated on MRI acquired at TEA.
RESULTS: MRIs at TEA of 34 infants were then analyzed: 17 in the MLE group and 17 in the SLE group. The postmenstrual age (PMA) at which MRIs were performed were comparable between the two study groups. The CeV as well as the PMA-corrected CeV were significantly higher in the MLE group than in the SLE group. No difference was found among the other brain volumes considered.
CONCLUSION: Our results suggest that the use of MLE in PN could promote CeV growth in ELBW infants, valued with MRI at TEA.
