Autonomic dysfunction in polyneuropathies: a report on 106 cases.

A Krone, P Reuther, U Fuhrmeister

    Journal of Neurology
    |January 1, 1983
    PubMed
    Summary

    Autonomic dysfunction frequently occurs in polyradiculoneuropathy. Pathophysiology involves organ denervation and reflex supersensitivity, necessitating early cardiac pacemaker insertion for life-threatening failure.

    Area of Science:

    • Neurology
    • Autonomic Nervous System Research
    • Clinical Medicine

    Background:

    • Autonomic dysfunction is a prevalent complication in diverse polyradiculoneuropathy presentations.
    • Understanding the specific types and prevalence of autonomic dysfunction is crucial for patient management.

    Purpose of the Study:

    • To investigate the spectrum and frequency of autonomic dysfunction in a cohort of polyradiculoneuropathy patients.
    • To elucidate the underlying pathophysiology of autonomic dysfunction in this condition.

    Main Methods:

    • Retrospective analysis of 106 cases with polyradiculoneuropathy.
    • Clinical assessment of autonomic function and organ-specific denervation.
    • Evaluation of reflex mechanisms and their sensitivity.

    Main Results:

    • Identified specific patterns and frequencies of autonomic dysfunction across the 106 cases.
    • Pathophysiology best explained by denervation insufficiency coupled with supersensitive reflex mechanisms.
    • Observed instances of life-threatening cardiac failure.

    Conclusions:

    • Autonomic dysfunction in polyradiculoneuropathy is primarily driven by organ denervation and reflex hypersensitivity.
    • Early intervention with transient cardiac pacemakers is recommended to prevent fatal cardiac events.
