Within a week of therapy, her fever and respiratory symptoms have resolved, and she was close to her preinfectious baseline. Reverse transcriptase-polymerase chain reaction was positive for SARS-CoV2 and she was treated with a five day course of hydroxychloroquine and azithromycin as she self-quarantined. Computed tomography of chest showed viral pneumonitis. Several days later she experienced fever, progressive worsening of dyspnea and disabling headaches. Then she presented with a cough and dyspnea of suddent onset. She was at that baseline for about a year. At her baseline, she had moderate headaches occurring in average twice per week. She improved on symptomatic and physical therapy. The autonomic testing findings (SFN and OCHOS) were attributed to Post Treatment Lyme Disease Syndrome. Workup for known causes of SFN (diabetes, pre-diabetes, parkinsonism, Parkinson's disease, history of heavy alcohol use, B12 and/or folate deficiency, active thyroid disease, celiac disease, hepatitis C, cancer, chemotherapy exposure systemic autoimmune disease, medications that have been associated with SFN) was negative.

Sudomotor testing showed reduced electrochemical skin conductance at feet (0.7 μS/kg, normal ≥1.14) and at hands 0.85 μS/kg, normal ≥1.03), which is also consistent with SFN. Skin biopsy showed reduced epidermal nerve fiber density (4.13 fibers/mm at distal leg, normal ≥6.06) consistent with SFN. Tilt test showed reduced orthostatic CBFv in middle cerebral artery (CBFv was reduced by 21% at the 10th minute of the tilt, normal decline <14%) while orthostatic hypotension orthostatic tachycardia and hypocapnia were absent which is consistent with OCHOS. Blood pressure responses to Valsalva maneuver and tilt test were normal, which is indicative of normal adrenergic sympathetic functions. Autonomic tests showed minimal parasympathetic dysfunction on deep breathing test (mean respiratory sinus arrhythmia = 7.0, normal >7.0).
She underwent standardized autonomic testing (deep breathing, Valsalva maneuver, tilt and sudomotor test) with cerebral blood flow velocity (CBFv) monitoring using transcranial Doppler. She experienced signs and symptoms typical for SFN (distal burning sensation without weakness and normal reflexes on neurological examination) and with symptoms of cerebral hypoperfusion (dizziness, brain fog and fatigue, all predominantly of orthostatic character). She was treated with several antibiotics (rifampin, ceftin, cefdinir) for possible incompletely treated Lyme disease and suspected coinfections. Her neurological evaluation including magnetic resonance imaging of the brain was unrevealing. Three months later she experienced headaches, several pain syndromes, disabling fatigue, brain fog and mood lability. She was treated with oral doxycylin for three weeks. Four years ago she experienced a tick bite with Bull's eye rash, arthralgia and swollen lymph nodes. She has a past medical history of headaches hypothyroidism (euthyroid on liothyronine), Lyme disease, SFN and OCHOS. Further studies are necessary to confirm the link between OCHOS/SFN and COVID-19 disease as well as to confirm the benefit of immunotherapy.Ī 64-year-old woman presented with a cough and dyspnea. This case suggests that post COVID-19 syndrome may present as an autoimmune OCHOS/SFN and that early immunotherapy may be effective. COVID-19 triggered exacerbation of OCHOS/SFN responded to immunotherapy with intravenous immunoglobulins. Patient recovered on symptomatic therapy. OCHOS (detected by the tilt test with transcranial Doppler monitoring) and SFN (confirmed by skin biopsy), and both OCHOS/SFN were attributed to Post Treatment Lyme Disease Syndrome of presumed autoimmune etiology. Initially, the patient was diagnosed with. This report describes a post COVID-19 patient who developed chronic fatigue, orthostatic dizziness and brain fog consistent with orthostatic hypoperfusion syndrome (OCHOS), a form of orthostatic intolerance, and painful small fiber neuropathy (SFN). Several postinfectious presumably autoimmune complications of COVID-19 affecting the brain or peripheral large nerve fibers have been reported. The clinical manifestations vary from no symptoms to multiple organ failure. The virus affects the human respiratory and other systems, and presents mostly as acute respiratory syndrome with fever, fatigue, dry cough, myalgia and dyspnea. Coronavirus disease (COVID-19) is a novel highly contagious infectious disease caused by the coronavirus SARS-CoV2.
