HIGH DENSITY LIPOPROTEIN CONCENTRATIONS IN NEWBORN INFANTS

Abstract The lipoprotein pattern was analyzed by agarose gel electrophoresis in 19 newborn infants of varying gestational age. The HDL concentration was determined by rocket Immunoelectrophoresis in another 41 newborn infants. Infants with a gestational age of <33 weeks had very low HDL concentrations compared to preterm infants with a gestational age of 33 weeks and term infants. In the first 5–10 days after birth the HDL concentration increased markedly in preterm infants (gestational age <37 weeks) whereas it remained unchanged in term infants.
