ResumoSix cases of nutritional copper deficiency were identified in a nursery institute for severely handicapped patients. All had been on prolonged enteral feeding of a copper-deficient diet and all had abnormalities related to the copper deficiency. Two of them had leukopenia, with or without macrocytic and normochromic anemia. After the oral administration of copper, the clinical and laboratory observations including neutrophil counts and serum copper and ceruloplasmin levels showed a complete recovery. The dietary copper requirement was estimated to be approximately 20 micrograms/kg/day for these patients, based on the correlation between the dietary copper intake and the levels of copper in the serum.
