From the Guidelines
Low serum copper and ceruloplasmin levels typically indicate copper deficiency, which requires supplementation to correct, with the recommended treatment being oral copper supplementation, usually copper gluconate or copper sulfate, at a dose of 2-4 mg elemental copper daily for adults until levels normalize, then 1-2 mg daily for maintenance, as supported by the most recent and highest quality study 1.
Implications of Low Serum Copper and Ceruloplasmin Levels
The implications of low serum copper and ceruloplasmin levels are significant and can lead to various health issues, including:
- Copper deficiency, which can cause anemia, neutropenia, neuropathy, and bone abnormalities
- Wilson's disease, a genetic disorder that can lead to liver disease, neurological dysfunction, and other complications
- Aceruloplasminemia, a rare disorder that can cause iron accumulation and neurological symptoms
Diagnosis and Treatment
Diagnosis of the underlying cause of low serum copper and ceruloplasmin levels is essential to determine the appropriate treatment approach. This may involve:
- Measurement of serum copper and ceruloplasmin levels
- Urinary copper excretion tests
- Genetic testing for Wilson's disease
- Imaging studies to evaluate liver and brain function
Management Approaches
Management approaches for low serum copper and ceruloplasmin levels depend on the underlying cause and may include:
- Oral copper supplementation for copper deficiency
- Chelation therapy with penicillamine or trientine for Wilson's disease
- Zinc supplementation for Wilson's disease
- Liver transplantation for severe liver disease due to Wilson's disease
Monitoring and Follow-up
Regular monitoring of serum copper and ceruloplasmin levels is essential to assess the effectiveness of treatment and adjust the management approach as needed. This may involve:
- Monitoring serum copper and ceruloplasmin levels every 1-3 months initially, then every 6-12 months once stabilized
- Adjusting the dose of copper supplementation or chelation therapy based on laboratory results and clinical symptoms
- Evaluating liver and brain function regularly to assess the progression of disease and the effectiveness of treatment.
From the Research
Implications of Low Serum Copper and Ceruloplasmin Levels
The implications of low serum copper and ceruloplasmin levels, specifically hypocupremia and low ceruloplasmin (Cp), can be severe and varied. Some of the possible implications include:
- Neurodegenerative disorders, such as Menkes disease, which is characterized by seizures, hypoactivity, and absence of visual contact 2
- Copper deficiency myelopathy, which can cause sensory ataxia, spastic gait, and posterior column dysfunction 3, 4
- Wilson disease, a genetic disorder that can cause copper toxicity and lead to neurological manifestations, such as tremors and difficulty walking 5
- Aceruloplasminemia, a rare genetic disorder that can cause low serum copper and ceruloplasmin levels, leading to neurological and hematological manifestations 6, 5
Clinical Significance
The clinical significance of low serum copper and ceruloplasmin levels can be indicative of an underlying condition, such as:
- Copper deficiency, which can be caused by gastrointestinal disease, surgery, or increased consumption of zinc 5, 3
- Malabsorption, which can be caused by celiac disease or other gastrointestinal disorders 4
- Genetic disorders, such as Menkes disease or Wilson disease, which can cause low serum copper and ceruloplasmin levels 6, 2
Diagnostic Considerations
When diagnosing low serum copper and ceruloplasmin levels, it is essential to consider the following:
- Serum copper and ceruloplasmin levels should be included in the diagnostic workup for myelopathy, especially in cases of otherwise unexplained subacute myelopathy involving the posterior columns 3
- Detection of hypocupremia in patients without a previous history of gastric surgery should lead to diagnostic testing for celiac disease, even in the absence of any obvious gastrointestinal symptoms 4
