Abstract
Protein-energy malnutrition in Kivu is associated with a discrete normocytic, normochromic anemia. An attempt to define the physiopathology of this anemia disclosed the following results. As compared with local controls, both iron and total iron binding capacity were low, but with siderophilin saturation and sideroblast counts either normal or elevated; serum and erythrocyte folate was normal, plasma vitamin B12 was normal or elevated, and serum ascorbic acid was normal or elevated. The riboflavin nutritional status was normal. During refeeding, iron and riboflavin deficiencies became apparent. Characteristic findings on admission were the presence of giant erythroblasts and a diminished erythrocyte survival time implicated to an intracorpuscular hemolysis. Two results from the present study could contribute to explanation for the aforementioned abnormalities: low plasma vitamin E levels and, perhaps more importantly, low plasma selenium levels. In conclusion, the anemia of protein-energy malnutrition, as observed in Kivu, is a classifiable nonadaptive anemia that cannot be explained by isolated iron or vitamin deficiencies and whose physiopathology is distinct from that of the anemia of chronic disorders. It is suggested that a selenium deficiency may play an important role in the pathogenesis of this anemia.
