Neuropathy associated with cryoglobulinemia.

C F Lippa, D A Chad, T W Smith

    Muscle & Nerve
    |September 1, 1986

    Summary

    Severe sensory ataxia in a patient was linked to IgM (kappa) cryoglobulin. Treatment with corticosteroids improved symptoms and reduced cryoglobulin levels, suggesting a therapeutic role.

    Area of Science:

    • Neurology
    • Immunology

    Background:

    • Subacute sensory ataxia is a rare neurological disorder characterized by sensory loss and gait instability.
    • Cryoglobulinemia, particularly IgM (kappa) type, can be associated with various systemic conditions.

    Observation:

    • A patient presented with severe subacute sensory ataxia.
    • The patient was diagnosed with IgM (kappa) cryoglobulinemia.

    Findings:

    • Nerve biopsy revealed both axonal degeneration and segmental demyelination, indicating a mixed neuropathy.
    • Corticosteroid therapy led to significant clinical improvement in ataxia.
    • Treatment also resulted in a 50% reduction in cryoglobulin concentration.

    Implications:

    • This case highlights a potential link between IgM (kappa) cryoglobulinemia and sensory ataxia.
    • Corticosteroid therapy may be an effective treatment for this specific type of cryoglobulin-associated neuropathy.
    • Further research is warranted to elucidate the pathogenic mechanisms and explore treatment options.
