Inflammatory and Autoimmune Axonal Neuropathies
Objective:
This article outlines the clinical patterns, diagnostic strategies, and treatment principles for patients with inflammatory and autoimmune axonal neuropathies.
Latest Developments:
Recent studies highlight the role of serum neurofilament light chain as a biomarker of the rate of active axonal injury and the increasing use of rituximab over cyclophosphamide for induction in neutrophil cytoplasmic antibody-associated vasculitis. Imaging modalities, such as magnetic resonance neurography and fludeoxyglucose positron emission tomography (FDG-PET), aid in identifying biopsy targets and monitoring disease activity.
Essential Points:
Inflammatory axonal neuropathies encompass a spectrum of immune-mediated disorders presenting with mononeuritis multiplex, asymmetric sensorimotor polyneuropathy, sensory ataxia, or plexopathy. The diagnosis requires a high degree of clinical suspicion, detailed electrodiagnostic evaluation, and consideration of systemic features. Nerve biopsy, although limited by patchy yield, can confirm the diagnosis and guide immunotherapy decisions. Treatment focuses on halting inflammation and preventing relapses, with corticosteroids as first-line induction and steroid-sparing agents for maintenance. A structured follow-up approach, including standardized neurologic examinations, functional assessments, and ancillary testing, is essential for tracking disease progression and treatment response.
