Case study: "Chronic vitamin A intoxication in infants fed chicken liver."

Chronic vitamin A intoxication in infants fed chicken liver.

Twin female infants were fed 120 gm of chicken liver homogenate daily for four months. They developed irritability, vomiting, and bulging anterior fontanelles. Computed tomograms of the brain revealed enlarged ventricles in both infants and dilated subarachnoid spaces in one. Plasma vitamin A concentrations were elevated. After all sources of vitamin A intake were stopped, the infants recovered without sequelae. The chicken liver homogenate contained 36,000 IU of vitamin A per 120 gm. Since infants often receive 4,000 units of vitamin A daily from fortified milk and vitamin supplements, they probably cannot be fed 60 gm of chicken liver safely more often than once weekly.
