Plasma alpha-tocopherol (vitamin E) levels and tocopherol-lipid ratio among children with protein-energy malnutrition (PEM).

The fat-soluble vitamin E (alpha-tocopherol) status of 47 malnourished children was assessed and compared with that of a control group of ten age-matched normal children. Plasma levels of alpha-tocopherol, total lipid and the ratio of alpha-tocopherol to total lipid were determined. The plasma vitamin E level was low, with a value of less than 11.61 mumol/l (500 micrograms/dl) in 40 (85%) of the malnourished children while the remaining seven (15%) children had values that ranged between 11.61 and 17.20 mumol/l (500-741 micrograms/dl). On the other hand, the tocopherol/total lipid ratio was less than 0.8 mg/g of total lipid in only seven of the malnourished children. The remaining 40 (85%) subjects had values that ranged between 0.8 and 1.96 mg/g of total lipid, whereas in the control group, both the plasma tocopherol levels and the tocopherol/lipid ratio were greater than 11.61 mumol/l (500 micrograms/dl) and 0.8 mg/g of plasma total lipid respectively.
