title: Transient hypertriglyceridemia of infancy.
abstract: A premature boy who had suffered from IRDS, bronchopulmonary dysplasia and retinopathy of prematurity developed massive hypertriglyceridemia (48.1 mmol/L) together with moderate hypercholesterolemia (12.6 mmol/L) at 5 months of age. Lipoprotein electrophoresis revealed a marked elevation of the level of the very low density lipoprotein fraction. There was a moderate decrease in the activity of a lipolytic enzyme, lipoprotein lipase (LPL). The child had neither liver or renal disorder nor any inflammatory disease. The hyperlipidemia disappeared spontaneously at the age of 3 years. The cause of the decreased LPL activity could not be established. A partial genetic deficiency in lipoprotein lipase appears the most likely explanation, since no signs of secondary lowering of LPL activity could be found.
