Long-term management of abetalipoproteinaemia. Possible role for vitamin E.

Eight patients with abetalipoproteinaemia have been followed for 3-4 to 15-8 years. Management included dietary fat restriction and supplements of the fat-solublevitamins A, E, and K. In the 3 oldest patients serial studies of retinal and neurological function suggest that treatment with large doses of oral vitamin E may have delayed the development or progression of the neurological and retinal lesions.
