This case illustrates autonomic failure in painful post-Lyme disease syndrome. Autonomic testing has shown supine hypertension, orthostatic hypotension, and hypocapnic cerebral hypoperfusion (HYCH). Small fiber neuropathy was painful, affecting sensory fibers. Patient noted improvement in the pain by about 40% after 12 month of intravenous immune globulins.

Autonomic testing showed mixed small fiber neuropathy, which can be responsible for both sensory complaints and dysautonomia. Dysautonomia was generalized, but mild and was associated with mild orthostatic intolerance. The patient has generalized hypermobility spectrum disorder (GHSD).

History Of

This patient presents with disabling pain in the feet for several years, chronic fatigue, and a history of Lyme disease. Neuropathy workup revealed autoimmune small fiber neuropathy with patchy distribution, associated with voltage-gated potassium channel antibodies (VGKC) antibodies. VGKCs modulate the nociceptive sensory threshold. Severe hypocapnic hyperventilation in this patient may be related to chronic pain and cerebral hypoperfusion.

The testing for this patient showed minimal dysautonomia, small fiber neuropathy, and orthostatic cerebral hypoperfusion syndrome (OCHOS). Small fiber neuropathy can be due to vitamin B12 deficiency. Mild dysautonomia is not suggestive of Parkinson’s disease or multiple system atrophy.

Normal Heart Rate

Patient experienced symptoms of orthostatic intolerance, most likely due to mild cerebral hypoperfusion due to hypocapnic hyperventilation and normal heart rate responses, which is typical for hypocapnic cerebral hypoperfusion (HYCH). In addition, there was significant small fiber cholinergic neuropathy affecting predominantly autonomic fibers, biopsy-proven.
