Severe Post-COVID-19 dysautonomia: a case report.

ABSTRACT

BACKGROUND: The emergence of dysautonomia as a consequence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; or COVID-19) is becoming more prevalent. We have seen evidence in several post-COVID patients and in the literature of varying degrees of autonomic dysfunction. Symptoms, among others, include inappropriate tachycardia, sweating, anxiety, insomnia and blood pressure variability from the effects of excessive catecholamine, as well as cognitive impairment, fatigue, headaches and orthostatic intolerance from decreased brain perfusion. CASE PRESENTATION We present a case of severe dysautonomia in a previously healthy 27-year-old runner. About five weeks after her initial mild COVID-19 infection, the patient began to develop weakness, which progressed into severe post-exertional fatigue, slowed cognition, headaches, blurred vision and generalized body aches. She also endorsed palpitations, especially when getting up from a seated or lying position as well as with mild exertion. She became reliant on her husband for help with her activities of daily living. Exam was significant for orthostasis; laboratory workup unremarkable. Over the following months, the patient's symptoms have improved slowly with fluid and sodium intake, compression stockings and participating in a graduated exercise program. CONCLUSIONS: Dysautonomia as a consequence of infection with COVID-19 is becoming increasingly discussed, especially as more patients recover from COVID-19. This is a case of a non-hospitalized patient with a mild initial presentation and significant, debilitating dysautonomia symptoms. More research on its pathophysiology, especially in relation to a precedent viral insult, as well as its treatment, is needed.
