Cystic fibrosis (CF) patients require a stable and sufficient supply of micronutrients. Since copper is an essential micronutrient for human development, a cross-sectional study was carried out to investigate the serum copper levels, serum copper/zinc (Cu/Zn) ratios, and their relationship with nutritional indicators in a group of CF patients. Anthropometric, biochemical, and dietary measurements, an abdominal ultrasound, and respiratory and pancreatic tests were conducted. Seventeen CF patients were studied (10 females, 59%), 76...

Copper deficiency can produce changes mimicking myelodysplasia, but its prevalence among haematology patients is unknown. This study evaluates the prevalence of deficiency in a population of patients with unexplained cytopenia(s) and dysplasia. Of 17 patients recruited, only one was found to have a low copper level. This is the first study evaluating hypocupremia in patients with isolated haematological manifestations. Our results suggest that copper deficiency is uncommon in this population, and the routine measurement of copper seems unlikely to be cost-effective...

Hypocupremia can result in a bi-lineage deficiency of leukocytes and erythrocytes. Although commonly seen from gastrointestinal malabsorption, hypocupremia can be further exacerbated with excessive zinc intake causing increased fecal copper excretion. Dietary supplementation is prevalent in the outpatient setting and must be considered as a possible source of hematologic pathologies.

Hypocupremia is a rare and under-recognised cause of bone marrow dysplasia and myeloneuropathy. A 47-year-old Caucasian woman had progressive ascending peripheral neuropathy and gait ataxia over 3 months and fatigue, dyspnoea and unintentional weight loss over 8 months. She had profound macrocytic anaemia and neutropenia. Initial workup included normal serum vitamin B12 Bone marrow biopsy was suggestive of copper deficiency. Serum copper levels were later confirmed to be undetectable. The patient received oral copper repletion which resulted in complete normalisation of haematological abnormalities 16 weeks later...

BACKGROUND: Zinc therapy is considered an effective and safe treatment for Wilson's disease. Hypocupremia-related anemia is rarely reported after long-term zinc administration or combination therapy with copper-chelating agent. CASE PRESENTATION: We herein report a 12-year-old girl with pre-symptomatic Wilson's disease diagnosed 5 years ago who presented with severe anemia after high-dose oral zinc for 4 years and 4 months. Her hemoglobin was gradually restored to the normal range after the adjustment of zinc dose and diet therapy for 4 months...

Menkes disease is a neurodegenerative and lethal pathology caused by gene mutations of the copper-transporting ATP-7A enzyme; it manifests itself by neurological symptoms and connective tissue changes of varying severity. Timely subcutaneous use of copper histidinate (Cu-His) is determinant for quality of life. We report the first experiences in Mexico on Cu-His synthesis and its safe use in 3 cases where hypocupremia and hypoceruloplasminemia were corroborated. With advice of the Hospital for Sick Children of Toronto Canada, we prepared a 500 µg/mL solution...

COMPARATIVE STUDY
Jin Jun Luo, Favio Bumanlag, Nae Dun
Copper deficiency (hypocupremia) or toxicosis (hypercupremia) may cause disorders of central and peripheral nervous systems. Hypocupremia causes myeloneuropathy resembling vitamin B12 deficiency. However, the clinical manifestations, particularly peripheral neuropathy (PN), of hypercupremia have not been adequately evaluated. To compare clinical, laboratory and electrodiagnositc features of PN between patients with hypocupremia and hypercupremia, we retrospectively reviewed the charts of patients with abnormal copper levels...

Celiac disease has been associated with several neurologic disorders which may result from micronutrient deficiencies, coexisting autoimmune conditions, or gluten sensitivity. Copper deficiency can produce multiple neurologic manifestations. Myeloneuropathy is the most common neurologic syndrome and it is often irreversible, despite copper replacement. We report the case of a 55-year-old man who presented with progressive proximal limb weakness and weight loss in the setting of untreated celiac disease without gastrointestinal symptoms...

We describe a sixteen year old with Wilson's disease on copper chelation and subsequent high dose oral zinc who developed severe anemia and neutropenia. Bone marrow aspirate done to evaluate the cause of bicytopenia revealed trilineage dysplasia. Correlating the clinical context with bone marrow and biochemical parameters, copper deficiency was suspected and he was given a trial of therapy, following which the hematological parameters improved. This case highlights hypocupremia as a reversible cause of bone marrow dysplasia in patients with Wilson's disease on chelation, where serum copper levels are not useful in the diagnosis...

Copper plays an essential role in numerous enzymatic reactions in the human body and hypocupremia manifests itself as cytopenias and/or neuropathy. Copper deficiency is also a mimic of dysplasia, and this may cause diagnostic difficulties with true myelodysplasia. In this case report, we present a patient with anaemia, thrombocytopenia and marginally decreased leucocyte count, who was found to have low copper levels. In addition, he had isolated 20q deletion and a small paroxysmal nocturnal haemoglobinuria clone, which have not been reported previously...

The conserved oligomeric Golgi (COG) complex is involved in intra-Golgi retrograde trafficking, and mutations in six of its eight subunits have been reported in congenital disorders of glycosylation (CDG). Here we report a patient showing severe acquired microcephaly, psychomotor retardation, seizures, liver dysfunction, hypocupremia, and hypoceruloplasminemia. Analysis of his serum glycoproteins revealed defects in both sialylation and galactosylation of glycan termini. Trio-based whole-exome sequencing identified two heterozygous mutations in COG2: a de novo frameshift mutation [c...

Hypocupremia, or copper deficiency, is a rare and underrecognized cause of bone marrow dysplasia. Most cases of copper deficiency in adults occurred historically in patients receiving total parenteral hyperalimentation or total parental nutrition. More recently, with the obesity epidemic and the prevalence of gastric bypass, cases of malabsorption-related copper deficiency have occurred. Copper deficiency can lead to significant cytopenias and possible neurologic sequelae, which can be misdiagnosed and mismanaged...

Copper deficiency resulting in hypocupremia is a rare cause of pancytopenia associated with a neurological syndrome. Hypocupremia may also occur as a consequence of excessive oral zinc consumption as described by Brewer et al and several other groups. Dental fixatives have been described as a potential source of hyperzincemia in patients. Despite the recently modified dental fixatives with safer zinc content, zinc poisoning results in hypocupremia secondary to inappropriate use of them can still happen and more likely be misdiagnosed...
