The clinical and biochemical evaluation of 6 patients with trichopoliodystrophy indicates that the disease process can begin in utero and is related to a selective abnormality in copper metabolism. Examination of 2 infants on the first day of life revealed abnormal neurological signs, a characteristic hair abnormality, and elevated levels of copper and ceruloplasmin. Decreased hepatic copper levels and increased urinary copper excretion were documented during the first week. The 2 neonates demonstrated a progressive decrease in blood copper levels in the first month of life. Four infants identified at ages 2 to 11 months had low values for blood copper and ceruloplasmin. All infants had progressive neurological dysfunction, and 4 of the 6 died at ages ranging from 2 1/2 months to 5 1/2 years. Parenteral copper therapy achieved normal blood and hepatic copper levels in 1 patient, but the copper values in the cerebral cortex and white matter were significantly decreased compared to control specimens.

A seven month old male with Menkes' disease ("Kinky hair") is presented. Low ranges of copper and caeruloplasmin were found. The angiogram of all intracranial arteries revealed torturous form. Biopsy of an extracranial artery (branch of the temporal artery) was normal. Authors review previously reported cases and possible causes that can contribute to hypomyelination of central nervous system.

A patient with Menkes' kinky hair syndrome was treated with oral CuSO4. Plasma copper, ceruloplasmin, red cell copper, and 24-hr urine copper excretion remained essentially unchanged. Intravenous copper infusion resulted in a rise of serum ceruloplasmin. During administration of a test meal of 64Cu(NO3)2, the patient was given alternately a volume of 0.9% NaCl or an equal volume of plasma intravenously. Radioactivity found in the blood was unchanged after each infusion period. During 427 days of subcutaneous copper, plasma p-phenylenediamine oxidase activity and plasma copper rose toward normal. Subsequent balance studies showed that the patient was in negative copper balance because of large losses in feces. Scanning electron microscopy demonstrated persistent pili torti.

The aim of this article is to emphasize the important role that copper plays in the function of nerve cells. We are reporting preliminary data which suggest that the swelling of axons which we produce in rats by iminodipropionitrile, IDPN, is due to its chelating action on copper, and how conversely supplementation with copper abolishes both symptoms and lesions. The copper values we obtained by atomic absorption spectrophotometry of the spinal cord and brain from the animals fully support this contention. In comparing these results with the diseases that are known to be due to copper deficiency, namely Menkes disease in man, swayback in lambs and several neurological mutant mice, we find not only similar axonal swellings, but also amelioration of symptoms and lesions by early administration of copper. Considering the main forms in which copper is present, we discuss the cuproproteins, i.e. ceruloplasmin and metallothionein, and their role in transport and delivery of copper to various organs. Further, the many cuproenzymes i.e. superoxide dismutase, tryptophan-2,3-dioxygenase, lysine oxidase, cytochrome oxidase, monoamine oxidases, tyrosinase, dopamine-beta-hydroxylase and d-amino levulinate dehydratase are noted for their roles in the nervous system. Finally, we suggest that neuronal copper deficiency should be more fully investigated as a possible etiological factor in the more common neurodegenerative diseases, such as Alzheimer's disease and amyotrophic lateral sclerosis, ALS.

We report a male infant with Menkes' disease who showed, at the age of 3 months, slow growth, hair abnormalities such as pili torti and white hair, and low levels of serum copper and ceruloplasmin. The exceptionally bright portions of his hair contained eumelanin and pheomelanin at levels only half those of normal Japanese controls. After subcutaneous administration of copper-histidinate for 2 months, his scalp hair changed to dark brown.

Occipital horn syndrome (OHS; Ehlers-Danlos syndrome type IX) belongs to the category of the copper metabolism disorders and is at present being investigated biochemically as is Menkes disease. We report a case of OHS in a 34-year-old male, which we believe to be the first Japanese case. He had been noted to have psychomotor retardation since his early childhood and now presents severe psychomotor retardation and muscle atrophy. He shows characteristic facial appearance, hyperelasticity of the skin, joint subluxation and generalized muscular atrophy. Laboratory investigations revealed a low serum copper and ceruloplasmin level as well as intestinal non-absorption of copper. Radiologic imagings showed occipital exostoses and bladder diverticula. The activity of lysyl oxidase, a copper-dependent enzyme involved in cross-link formation in collagen, was decreased in a skin-biopsied specimen. Electronmicroscopic investigation of a muscle biopsy showed irregularity of the myofibrillar network and accumulation of the concentric laminated bodies in the subsarcolemmal regions.

These studies were designed to determine if macular mutant mouse, which is a proposed animal model of Menkes' kinky-hair disease, is sensitive to the acute toxic effect of Cu as compared to normal and heterozygote mice. Single sc injection of Cu were administered to 6- to 8-day-old mice, and mortalities were recorded for 30 days. The copper treatment at high doses (12 to 25 mg Cu/kg) was very toxic to mutant mice as compared to normal mice, and almost all mutant mice died within 10 days after injection. The effect of Cu toxicity on heterozygote mice was intermediate. The LD50 values 3 days after injection of Cu were 29.5 mg Cu/kg for normal mice, 23.5 mg Cu/kg for heterozygote mice, and 15.5 mg Cu/kg for mutant mice. In Cu-injected mutant mice (11 and 18 mg Cu/kg), significant elevations in serum aspartate aminotransferase and lactate dehydrogenase activity occurred as compared to Cu-injected normal and heterozygote mice. However, no significant elevations in serum creatinine and urea nitrogen contents in Cu-injected mutant were observed as compared to normal and heterozygote mouse. No significant differences in hepatic metallothionein(MT) and MT-1 mRNA, and serum ceruloplasmin oxidase activity levels were observed between Cu-injected normal and mutant mouse. These results indicated that macular mutant mice was sensitive to the acute toxic or hepatotoxic effects of Cu as compared to normal and heterozygote mice.

We describe a neurological disease, seen in the elder sister of identical twins, with dysarthria, involuntary movements, spastic gait, slightly low serum copper, borderline low to normal serum ceruloplasmin, normal urinary copper, and a high hair copper concentration. This neurological disorder appears to differ from others associated with abnormal copper metabolism such as Wilson's or Menkes' kinky hair disease.

The patient developed myoclonic seizures at 3 months of age and his hair demonstrated the pili torti pattern. The low serum copper content and ceruloplasmin confirmed the diagnosis of Menkes disease. The characteristic signs on the images were: high echo level regions in the cerebrum as detected by brain ultrasonography, low density areas of white matter detected by CT scan, and low signal intensities of white matter by both T1 and balanced MR images.
