Hypolipidemia
Chylomicron retention disease (Anderson disease)
In chylomicron retention disease, a hereditary disorder, the body cannot make chylomicrons. Affected infants tend to develop fat malabsorption, steatorrhea, and failure to thrive and may develop symptoms of central nervous system damage similar to those of abetalipoproteinemia. Levels of lipids in the blood are measured. In infants whose levels are very low, especially ones that are normally elevated after a meal, a biopsy of the intestine is done. Treatment is supplements of dietary fats and vitamins A, D, E, and K.
