Immune-Mediated Neuropathies: Pathophysiology and Management.

Area of Science:

• Neuroimmunology
• Peripheral Nervous System Disorders

Background:

• Immune system dysfunction can lead to peripheral nervous system damage, including demyelination and axonal degeneration.
• Mechanisms involve macrophage infiltration, inflammation, and Schwann cell proliferation, with diverse etiologies sometimes triggered by infection.

Purpose of the Study:

• To review the immunological and pathophysiological mechanisms of dysimmune neuropathies.
• To discuss electrophysiological characteristics, laboratory features, and treatment options for these disorders.

Main Methods:

• Review of existing literature on immune-mediated neuropathies.
• Discussion of animal models for inflammatory polyradiculoneuropathies.
• Analysis of antibody detection and electrophysiological findings.

Main Results:

• Specific antibodies (anti-glycoconjugate, paraneoplastic) aid in classification and diagnosis, indicating molecular mimicry or immune reactions to tumors.
• Electrophysiological findings like conduction blocks help differentiate subtypes, such as multifocal motor neuropathy with conduction block and Lewis-Sumner syndrome.

Conclusions:

• Dysimmune neuropathies encompass a range of disorders with distinct immunological and pathophysiological underpinnings.
• Accurate diagnosis and classification rely on integrating clinical, immunological, and electrophysiological data for effective treatment and prognosis.
