In biology, redox reactions are essential and sometimes harmful, and therefore, iron metabolism is tightly regulated by cuproproteins. Since the state of copper in iron overload syndromes remains unclear, we investigated whether copper metabolism is altered in these syndromes. Eleven patients with iron overload syndromes participated in this study. The(More)
BACKGROUND Copper toxicity steadily affects the livers of patients with Wilson disease. However, the toxic effect of copper on serum aspartate and alanine aminotransferase levels remains to be clarified as a prerequisite for diagnostic tests. The clinical records of 33 cases were analyzed to clarify the natural history of Wilson disease. Phenotypes were(More)
The interaction between iron and copper has been discussed in association with human health and diseases for many years. Ceruloplasmin, a multi-copper oxidase, is mainly involved in iron metabolism and its genetic defect, aceruloplasminemia (ACP), shows neurological disorders and diabetes associated with excessive iron accumulation, but little is known(More)
BACKGROUND AND AIMS Wilson disease (WD) is an inherited disorder of copper metabolism, and an international group for the study of WD (IGSW) has proposed three phenotypes for its initial presentation: acute hepatic, chronic hepatic, and neurologic phenotypes. Characterization of the acute hepatic phenotype may improve our understanding of the disease. (More)
