  • Title: Autonomic involvement in Guillain-Barré syndrome: an update.
    Author: Zaeem Z, Siddiqi ZA, Zochodne DW.
    Journal: Clin Auton Res; 2019 Jun; 29(3):289-299. PubMed ID: 30019292.
    Abstract:
    BACKGROUND: Guillain-Barré syndrome (GBS), an inflammatory, usually demyelinating polyradiculopathy, is characterized by ascending symmetrical limb weakness, sensory disturbances, and absent or reduced deep tendon reflexes. There is extensive literature suggesting that GBS is associated with autonomic dysfunction in up to two-thirds of patients. However, it is interesting that there is still no consensus amongst medical professionals regarding whether GBS patients should be routinely screened for autonomic nervous system (ANS) neuropathy. This is an important issue, as the mortality rate from presumed ANS abnormalities now exceeds that of respiratory failure. Given the long interval since this literature was last comprehensively reviewed, an update on this topic is warranted. METHODS: A PubMed search yielded 193 results with the terms "GBS or Guillain-Barré syndrome and autonomic symptoms" and 127 results with the terms "GBS or Guillain-Barré syndrome and dysautonomia." RESULTS: This review will summarize the current literature involving GBS and autonomic dysfunction in terms of presentation, management, and a brief discussion of prognosis. We also examine prospective approaches that may be helpful and update a proposed management plan.
