Vitamin a hepatotoxicity in multiple family members
Gerald Y. Minuk, James K. Kelly, Wei‐Sek Hwang – 1 March 1988 – Three of five family members experienced symptoms and biochemical evidence of hepatitis that could not be explained on the basis of infectious, metabolic or immunologic disorders of the liver. A history of prolonged ingestion of moderate amounts of vitamin A (20,000 to 45,000 IU per day for 7 to 10 years) was obtained in each of the three family members and was absent in the remaining two unaffected individuals. A liver biopsy performed in one family member confirmed the diagnosis of vitamin A toxicity.
