Study Summary

The term post-acute COVID-19 syndrome or Long COVID is a disabling syndrome that persists beyond the 3-month convalescence period after COVID-19 infections. This syndrome affects mostly women (\~80%), present with chronic tachycardia and Orthostatic intolerance symptoms without any identifiable cause. In addition, non-specific symptoms such as fatigue, headache, and "brain fog", commonly described in POTS patients are also present in this novel condition, recently named post-COVID-19 tachycardia syndrome, POTS variant. Reduced Vagal activity and unresolved inflammation is post-COVID-19 POTS is hypothesized as the cause of Long COVID

Primary Outcome

Evaluate immune cell activation in post-COVID-19 POTS and patients with history of COVID-19 infection without sequelae and correlate this with the degree of decreased PNS activity. The primary endpoint is IL-6 levels

Interventions

  • DIAGNOSTIC_TEST Levels of inflammatory cytokine ( IL-6) in post-COVID-19 POTS and controls
  • DIAGNOSTIC_TEST Levels of inflammatory cytokine ( IL-6) in controls
  • DIAGNOSTIC_TEST Effect on inflammation after chronic PNS stimulation
