PURPOSE OF REVIEW: This article discusses the clinical features, pathophysiology, and management of primary and secondary acquired immune axonal neuropathies.
RECENT FINDINGS: Although there are many collagen vascular disorders associated with vasculitic neuropathy, a quarter of cases have been described to be due to nonsystemic vasculitis of the peripheral nervous system. Enhanced surveillance and aggressive treatment of conditions such as cryoglobulin-related vasculitic neuropathy with cyclophosphamide, rituximab, and alfa interferons has led to improved morbidity and mortality, however, many cases of immune axonal acquired neuropathy are still associated with poor outcomes. Acute motor axonal neuropathy (AMAN) and acute motor sensory axonal neuropathy (AMSAN) are well-characterized variants of Guillain-Barré syndrome.
SUMMARY: Characterizing the clinical and electrophysiologic phenotype can help diagnose conditions such as nonsystemic vasculitic neuropathy, AMAN, AMSAN, and immune small fiber neuropathy, while careful evaluation of systemic features is key to identifying secondary immune axonal neuropathies such as vasculitic neuropathy related to collagen vascular disease. Additional research is needed to determine the exact immune pathogenesis and optimized treatment regimens for all acquired immune axonal neuropathies.
