Copper levels in patients with celiac neuropathy

Area of Science:

• Neurology
• Gastroenterology
• Clinical Medicine

Background:

• Neurological complications, including neuropathy, are recognized in celiac disease (CD).
• Previous research suggested copper deficiency (hypocupremia) as a potential cause for neuropathy in CD patients.
• This study questions the established link between hypocupremia and neurological issues in CD.

Purpose of the Study:

• To investigate the relationship between copper levels and peripheral neuropathy in patients diagnosed with celiac disease.
• To test the hypothesis that celiac disease patients with polyneuropathy are not copper deficient.

Main Methods:

• Retrospective review of medical records for patients meeting criteria for CD and peripheral neuropathy.
• Assessment of serum copper levels and other clinical parameters in the selected patient cohort.

Main Results:

• Eighteen patients with CD and peripheral neuropathy were analyzed.
• The majority of patients (89%) exhibited normal serum copper levels; two had mild hypercupremia.
• No patients in the study demonstrated hypocupremia. Small fiber neuropathy was more prevalent (78%) than large fiber neuropathy (22%).

Conclusions:

• This study found no evidence of copper deficiency in celiac disease patients presenting with peripheral neuropathy.
• The findings do not support a direct relationship between hypocupremia and peripheral neuropathy in this cohort of CD patients.
