title: Fatty acid composition of plasma and erythrocyte phospholipids in preterm infants.
abstract: Erythrocyte and plasma phospholipid fatty acids were determined in preterm babies at 0, 6 and 10 weeks. There were highly significant changes in fatty acid composition between birth and 6 weeks in both plasma and erythrocyte phospholipids, the changes being more numerous and quantitatively greater in phosphatidyl choline. There was little further change by 10 weeks. Linoleic acid increased by approximately 100% at 6 weeks in plasma phosphatidyl ethanolamine and 200% in phosphatidyl choline. In erythrocyte phosphatidyl ethanolamine, linoleic acid increased by approximately 150% at 6 weeks and in phosphatidyl choline increased 170%. Arachidonic acid decreased by 54%. The essential fatty acid status of the preterm babies studied using contemporary feeding regimes was satisfactory and by 6 weeks phospholipid fatty acid profiles were comparable with published data for normal healthy breast-fed infants.
