[Rare nutritional deficiency anemia: deficiency of copper and vitamin E]

Abstract

Copper deficiency anemia occurs in some specific situations if supplemental copper is not given: low birth-weight premature infants fed milk only, protracted total parenteral nutrition, chronic diarrhea with severe malnutrition. Severe neutropenia precedes the onset of sideroblastic anemia. Iron therapy is ineffective. Diagnosis is established by the low serum copper concentrations, the delayed osseous anomalies, and the dramatic response to copper therapy. Low serum vitamin E concentrations may be found in low birth-weight premature infants aged six to ten weeks with hemolytic anemia. In such cases, vitamin E therapy is effective. This condition occurs more often in infants fed milk formulas without supplemental copper and in infants given high doses of iron. Whether vitamin E deficiency causes anemia is still an open question. Preventive vitamin E supplementation is only partly effective.
