[Iron metabolism during proteoenergetic malnutrition in children].
The iron stores are normal in marasmic kwashiorkor in kivu, but they notably decrease on re-feeding. On admission, the total iron binding capacity depends not only on the severity of the protein depletion but also on the iron stores. There exists an abnormality of the iron release from the stores; this cannot be attributed to the hypotransferrinemia or to the hypoceruloplasminemia, which are too moderate, nor to an ascorbic acid deficiency, but possibly to the inflammatory state which is a feature of kwashiorkor. The iron deficiency which occurs on re-feeding is not explained by abnormalities of iron absorption or by increased iron loss, but by the raised requirement for iron. Parental iron treatment alone is required to normalise the packed cell volume and the red cell volume after re-feeding.
