Abstract

Fetal organs require much lipid for growth, but the cord blood had low TG concentrations, compared to adult serum. We investigated the association between the concentration of apolipoprotein A-V (apoA-V) and lipid profile in cord blood and neonatal serum. ApoA-V was identified as an important determinant of plasma triglyceride concentrations. We sought to determine the association between serum apoA-V concentrations and lipoprotein profile in preterm infants and its early postnatal change. Sixty-three neonates (35 males and 28 females; 15 term and 48 preterm) were included. Serum lipoprotein profile and apoA-V concentrations were determined at birth and 1 month. Cord blood apoA-V concentrations in appropriate-for-gestational age infants were extremely low (13.1 ± 3.4 ng/mL in term infants, 4.4 ± 0.9 ng/mL in preterm infants) compared with adult values, and those of small-for-gestational age infants were further low (6.4 ± 4.2 ng/mL, 2.2 ± 1.3 ng/mL, respectively). During the first month, serum apoA-V concentration markedly increased, and the concentration of preterm appropriate-for-gestational age infants caught up, whereas that of preterm small-for-gestational age infants did not. At birth, apoA-V concentration positively corr...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
