Copper Deficiency in Liver Diseases: A Case Series and Pathophysiological Considerations

Area of Science:

• Hepatology
• Nutritional Science
• Trace Element Metabolism

Background:

• Copper is essential for cellular energy metabolism, antioxidant defense, and fibrogenesis.
• Liver disorders involve critical cellular processes where copper acts as a cofactor.
• The link between copper deficiency and liver disease pathogenesis is understudied.

Purpose of the Study:

• To investigate the occurrence and characteristics of copper deficiency in patients with diverse liver diseases.
• To describe the clinical presentation and biochemical findings in liver disease patients with copper deficiency.

Main Methods:

• Case series analysis of 12 liver disease patients.
• Assessment of serum and hepatic copper concentrations.
• Clinical evaluation including liver function tests and patient history.

Main Results:

• 12 patients with liver disease showed signs of copper deficiency (serum copper < 70-155 μg/dL, hepatic copper < 10 μg/g dry weight).
• Common presentations included acute-on-chronic liver failure and decompensated cirrhosis.
• Associated features were steatohepatitis, iron overload, malnutrition, and recurrent infections.

Conclusions:

• Copper deficiency is prevalent in patients with various liver conditions.
• The clinical significance and underlying mechanisms of copper deficiency in liver disease warrant further investigation.
• Copper supplementation may improve biochemical markers and liver function in select patients.
