title: Clinical uses and abuses of vitamin E in children.
abstract: The major benefits arising from elevated dosages of vitamin E have been the relief of symptoms of vitamin E deficiency in humans with abetalipoproteinemia and chronic cholestasis. In addition, supplements of vitamin E prevent the isolated vitamin E deficiency that has recently been associated with spinocerebellar symptoms. In keeping with the view that newborn infants, and especially premature infants, suffer from vitamin E deficiency, elevated dosages of vitamin E have been administered to prevent the anemia of premature infants, retrolental fibroplasia, bronchopulmonary dysplasia, and intraventricular hemorrhage. However, the results have been conflicting. Furthermore, some infants treated with vitamin E die unexpectedly. The life-threatening hazard of such treatments has been attributed mainly to polysorbates that are used as detergents in preparations of vitamin E for intravenous use rather than to vitamin E itself. The possibility that vitamin E, in its action as an antioxidant, inhibits the generation of superoxide anion in leukocytes is examined in this paper.
