title: Lipoprotein profile and cholesteryl ester transfer protein in neonates.
abstract: Undernourishment in utero appears to be associated with persisting changes in the metabolic, endocrine, and immune functions. In this study, we determined the influence of birth weight on the lipoprotein profile and cholesteryl ester transfer protein (CETP), which promotes a proatherogenic lipoprotein profile in plasma by determining the chemical, physical, and biologic properties of the respective lipoprotein particles. Triglyceride (TG) concentrations were highest and high-density lipoprotein (HDL)(2)-cholesterol levels were lowest in small for gestational age (SGA) neonates. CETP-mass was determined by enzyme-linked immunosorbent assay (ELISA) and CETP-activity by using exogenous lipoproteins. Cholesteryl ester transfer was determined as transfer of radiolabeled cholesteryl esters (CE) from HDL to apolipoprotein B-containing lipoproteins. CETP mass was lowest and cholesteryl ester transfer was highest in SGA neonates. CETP-activity did not differ among the neonates. Our results suggest that increased and decreased nourishment in utero affects the lipoprotein profile and CETP in neonates. High TG and low HDL(2) levels in SGA neonates might result from increased cholesteryl ester transfer and, may in part, explain the increased risk of coronary heart disease (CHD) of small for gestational age neonates in later life.
