Abstract

Objectives To study the association of hypertriglyceridemia and of lipid tolerance with clinical and nutritional data in preterm infants receiving routine parenteral nutrition. Design We retrospectively studied 672 preterm infants (gestational age <32 weeks) with birth weight <1250 g, consecutively admitted to our NICU, born between 2004 and 2018. Selected prenatal data and interventions, parenteral intakes and diseases were considered. Hypertriglyceridemia was defined as plasma triglycerides >250 mg dL −1. Lipid tolerance was defined as the ratio of plasma triglycerides to the intravenous lipid intake at the time of sampling. Variables associated to hypertriglyceridemia and to lipid tolerance were identified by multiple logistic and linear regression analyses. Results Hypertriglyceridemia occurred in 200 preterm infants (30%), ranging from 67% at 23 weeks to 16% at 31 weeks' gestation. In 138 infants (69%) hypertriglyceridemia occurred at a lipid intake of 2.5 g kg −1 or less. Lipid tolerance was reduced especially in infants of less than 28 weeks’ gestation (14.3 ± 9.3 vs 18.8 ± 10.2, respectively, p < 0.001). Lipid tolerance was negatively associated with respiratory distress syndrome (OR = −1.14, p = 0.011), patent ductus arteriosus (OR = −1.73, p < 0.001), small for gestational age (OR = −2.96, p < 0.001), intraventricular haemorrhage (OR = −3.96, p < 0.001), late onset sepsis (OR = −8.56, p = 0.039). Conclusion Preterm infants on routine parenteral nutrition were able to tolerate markedly lower intravenous lipid intakes than the recommended target values of current guidelines.
