Buchman AL, Keen CL, Vinters HV, Harris E, Chugani HT, Bateman B, Rodgerson D, Vargas J, Verity A, Ament M: Copper deficiency secondary to a copper transport defect: a new copper metabolic disturbance. Metabolism. 1994 Dec;43(12):1462-9.
We describe a 21-year-old man who developed copper deficiency manifested as a demyelinating neuropathy, chronic intestinal pseudo-obstruction, osteoporosis, testicular failure, retinal degeneration, and cardiomyopathy with a tortuous aorta. His serum copper was low and did not increase despite administration of large doses of intravenous copper sulfate. The ceruloplasmin level as measured by an antibody technique was normal, yet ceruloplasmin (Cp) oxidase activity was very low. The Cp amino acid sequence was normal. This suggests that the copper deficiency was caused by a defect in hepatic processing of copper for incorporation into Cp. |
