This case study highlights pure autonomic failure, a condition affecting both sympathetic and parasympathetic nervous systems. Effective treatment with fludrocortisone and metoclopramide significantly improved patient symptoms.

Area of Science:

  • Neurology
  • Cardiology
  • Endocrinology

Background:

  • Autonomic dysfunction can manifest with a variety of symptoms impacting multiple organ systems.
  • Orthostatic hypotension, a common symptom, indicates impaired cardiovascular reflexes.

Observation:

  • A 64-year-old woman presented with a 5-year history of constipation/diarrhea, reduced sweating, dry mouth and eyes, painful urination, and orthostatic hypotension.
  • Cardiovascular reflex analysis indicated both sympathetic and parasympathetic nervous system failure.
  • Markedly reduced norepinephrine levels were observed in both supine and tilted positions.

Findings:

  • Norepinephrine infusion led to a significant blood pressure increase, suggesting denervation hypersensitivity.
  • The patient was diagnosed with pure autonomic failure.

  • Initiation of 9 alpha fludrocortisone and metoclopramide resulted in substantial and lasting symptom relief.

    • Implications:

    • This case underscores the importance of comprehensive autonomic function testing for diagnosing complex autonomic neuropathies.
    • Pharmacological interventions targeting specific autonomic pathways can effectively manage symptoms of pure autonomic failure.
    • Early diagnosis and treatment are crucial for improving quality of life in patients with autonomic disorders.
