Schwann cell dysfunction in uraemia.

J J Dinn, D L Crane

    Journal of Neurology, Neurosurgery, and Psychiatry
    |October 1, 1970
    PubMed
    Summary
    This summary is machine-generated.

    Uraemia causes segmental demyelination in sural nerve fibres, often unmasking latent peripheral neuropathy during dialysis. Creatinine retention and dialysis may induce metabolic dysfunction in Schwann cells.

    Area of Science:

    • Neurology
    • Nephrology
    • Biochemistry

    Background:

    • Uraemia is associated with peripheral neuropathy.
    • Dialysis is a common treatment for end-stage renal disease.
    • The precise mechanisms linking uraemia, dialysis, and neuropathy are not fully understood.

    Purpose of the Study:

    • To investigate the presence and nature of peripheral nerve damage in uraemic patients.
    • To explore the potential role of dialysis in precipitating or exacerbating neuropathy.
    • To discuss the correlation between uraemia, dialysis, and metabolic dysfunction in Schwann cells.

    Main Methods:

    • Examination of individual sural nerve fibres.
    • Clinical assessment for peripheral neuropathy.
    • Analysis of biochemical changes associated with dialysis.

    Main Results:

    • Segmental demyelination was observed in 10 out of 12 uraemic subjects.
    • Peripheral neuropathy was clinically evident in only two cases.
    • Dialysis appeared to unmask underlying demyelination in subjects with latent neuropathy.

    Conclusions:

    • Segmental demyelination is a common finding in uraemia, even without overt neuropathy.
    • Dialysis-induced biochemical changes can precipitate neuropathy in susceptible individuals.
    • Metabolic dysfunction in Schwann cells, potentially linked to creatinine retention and dialysis, may underlie uraemic neuropathy.
