Abstract

Serum lipoproteins were explored on the first day of life (D1) and on the sixth day (D6) in blood drawn by peripheral venipuncture from 43 normal term newborns, 22 breast-fed and 21 formula-fed, and were compared to those of a control group of 28 young adults. With the exception of apolipoprotein E (Apo E), values of lipoprotein components obtained at D1 were similar, although generally slightly lower than those previously reported for cord blood serum. Total Apo E concentration at D1 (71 +/- 25 mg/l) was much higher than that obtained for the adult group (30 +/- 7 mg/l). Apo E distribution within the lipoprotein spectrum confirmed the presence of an already known Apo E-rich high density lipoprotein subfraction, which was responsible for the high total Apo E level at birth. The rise of lipoproteins of low density from D1 to D6, as evidenced by the increase of very low density lipoprotein + low density lipoprotein cholesterol and low density lipoprotein apolipoprotein B concentrations, was shown to be diet dependent. It was significantly less important in newborns fed a standard formula moderately enriched in unsaturated fatty acids than in breast-fed newborns.
