Vitamin E deficiency and associated neurological deficits in children with protein-energy malnutrition.
Vitamin E is important in maintaining normal neurological structure and function. In this study, 100 children with protein-energy malnutrition (PEM) were studied and compared to a suitably age-matched control group. Posterior column deficits, cerebellar deficits, and problems with fine motor coordination were present to a significant degree in the PEM subjects. The presence of neurological signs was correlated with various parameters of vitamin E deficiency, including low serum alpha-tocopherol levels and a low tocopherol/total lipid ratio which was present in 92 per cent of subjects. There was good concordance between vitamin E levels and vitamin E to serum lipid ratio in assessing vitamin E deficiency. We conclude that vitamin E deficiency is prevalent, to a hitherto unsuspected degree, in children with PEM and that these malnourished children have significant neurological deficits attributable to low vitamin E levels. This observation is of clinical significance as the neurological deficits are potentially reversible with vitamin E supplementation.
