Revision as of 11:21, August 13, 2021
Long COVID, long tail covid, Post-Acute Sequelae of COVID-19 (PASC), post-acute COVID-19 and ongoing COVID are terms used to describe a group of long term health problems that are found in a significant minority of people who developed COVID-19 and remain ill a number of weeks or months later.
Overview[edit | edit source]
Pathophysiology[edit | edit source]
Infection and immunity[edit | edit source]
A range of antibodies have been found in patients with persistent post-acute COVID symptoms. Elevated G-protein coupled receptor autoantibodies have been found.[1] One study founded elevated antinuclear antibody (ANA) titles in 43.6% of long COVID patients twelve months after symptom onset.[2]
Long COVID may be associated herpesvirus reactivation such as Epstein-Barr Virus,[3] which has been shown to cause elevations of certain G-protein coupled receptor autoantibody types.[4][5][6][7]
Neurological and neuropsychiatric[edit | edit source]
Cardiovascular[edit | edit source]
Pulmonary[edit | edit source]
In a single cardiopulmonary exercise test, Post-COVID-19 patients exhibited markedly reduced peak exercise aerobic capacity (VO2) compared to controls and impaired oxygen extraction, even in those without cardiopulmonary disease.[8]
Comparison to other conditions[edit | edit source]
Findings | Long COVID | Post-acute SARS | ME/CFS | POTS | MCAS |
---|---|---|---|---|---|
G-protein coupled receptor autoantibodies | β2- and α1-adrenoceptors, angiotensin II AT1-, muscarinic M2-, MAS-, nociceptin- and ETA-receptors | M3 and M4 muscarinic acetylcholine receptors, as well as ß2 adrenergic receptors | α1, β1 and β2 adrenergic receptor autoantibodies | ||
Post-SARS syndrome[edit | edit source]
ME/CFS[edit | edit source]
Postviral fatigue syndrome[edit | edit source]
Chronic fatigue and Idiopathic chronic fatigue[edit | edit source]
POTS[edit | edit source]
MCAS[edit | edit source]
