Leucocyte ascorbic acid levels in Nigerian children with protein-energy malnutrition.

Leucocyte ascorbic acid (LAA) levels were estimated in 26 Nigerian infants and preschool children with protein energy malnutrition (PEM) in order to ascertain their ascorbic acid status. The children included eight with kwashiorkor, 12 with marasmus and six with marasmic kwashiorkor. The mean (SD) LAA level of 13.7 (8.2) micrograms/10(8) leucocytes in the malnourished children did not vary significantly from the mean level of 14.4 (8.8) micrograms/10(8) leucocytes found in 26 age-matched controls, and the values were unrelated to the presence or absence of megaloblastic change in the 14 bone marrows examined. It was concluded that ascorbic acid deficiency was not prevalent amongst children with PEM in Lagos, and was therefore not usually contributory to the anaemia, megaloblastic changes or other features of the syndrome seen in Nigerian children in Lagos.
