Inflammatory neuropathy

Last edited: 4/15/2026

Overview

Inflammatory neuropathy involves immune-mediated damage to peripheral nerves, often characterized by neuropathic pain, weakness, and sensory disturbances. Antiglycolipid antibodies, cytokines, and adhesion molecules play significant roles in its pathogenesis 1.

Diagnosis

  • Key Diagnostic Criteria: Presence of neuropathic symptoms, elevated antiglycolipid antibodies, and possibly elevated cytokine levels 1.
  • Recommended Tests: Serological testing for antiglycolipid antibodies, nerve conduction studies, and cerebrospinal fluid analysis for inflammatory markers 1.
  • Grading: Severity often assessed using clinical scales like the Inflammatory Neuropathy Cause and Treatment (INCAT) disability score 1.
  • Management

  • First-Line Treatments: Corticosteroids (e.g., prednisone) to reduce inflammation 1.
  • Adjunctive Treatments: Immunosuppressive agents such as intravenous immunoglobulin (IVIG) and disease-modifying antirheumatic drugs (DMARDs) like methotrexate 1.
  • Specific Drug Classes: IVIG typically administered at doses of 2 g/kg over 2-5 days 1.
  • Special Populations

  • Pregnancy: Management requires careful consideration of teratogenic risks; corticosteroids are often preferred over other immunosuppressants 1.
  • Elderly: Close monitoring for side effects of immunosuppressive therapies is crucial due to increased vulnerability 1.
  • Key Recommendations

  • Initiate corticosteroid therapy for confirmed inflammatory neuropathy to manage symptoms and reduce inflammation (Evidence: Strong 1).
  • Consider IVIG in patients refractory to corticosteroids or with severe disease (Evidence: Moderate 1).
  • Tailor immunosuppressive therapy in pregnant women, prioritizing safety over aggressive treatment (Evidence: Expert opinion 1).
