We report the cases of two adult patients with cystic fibrosis affecting the pancreas and liver, who also had severe vitamin E deficiency and neurologic disease. The most prominent clinical features were abnormal eye movements, diminished reflexes, decreased vibratory and position sense, ataxia, and muscle weakness. Treatment with intramuscular injections of vitamin E partially corrected the neurologic deficits. Vitamin E absorption tests documented severe malabsorption, which was later alleviated by the addition of dessicated ox bile to the regimen of alpha-tocopheryl acetate. These studies suggest that a decreased intraluminal concentration of bile salts is an important factor in the development of severe vitamin E deficiency and in the poor response to oral replacement therapy that is seen in some patients with cystic fibrosis.
