Summary
Monoclonal proteins are linked to peripheral neuropathy, affecting about 10% of patients with unknown causes. Evaluating chronic polyneuropathies for plasma cell dyscrasia is crucial.
Area of Science:
- Neurology
- Immunology
- Oncology
Background:
- Monoclonal proteins are increasingly recognized in peripheral neuropathy development.
- Approximately 10% of patients with idiopathic peripheral neuropathy harbor a monoclonal protein, a significantly higher prevalence than in the general population.
Purpose of the Study:
- To review the heterogeneous nature of peripheral neuropathies associated with monoclonal proteins.
- To highlight the clinical, electrophysiological, and immunopathological evidence linking monoclonal proteins to specific neuropathy subtypes.
Main Methods:
- Review of clinical data.
- Electrophysiological assessments.
- Immunopathological investigations.
Main Results:
- Peripheral neuropathies associated with monoclonal proteins are diverse.
- Specific antibody targets (anti-MAG, anti-sulfatide, anti-chondroitin sulfate, anti-GM1) define distinct neuropathy types (demyelinating sensory, axonal sensory, motor).
Conclusions:
- Monoclonal protein-associated neuropathies represent a heterogeneous group.
- Patients with chronic polyneuropathies warrant evaluation for underlying plasma cell dyscrasia.
