Implication of inflammatory markers in post COVID syndrome

Post-COVID syndrome was described in the context of a survey of prolonged COVID-19 symptoms for the first time in 2020, run by the Patient-Led Research Collaborative, citizen’s scientist group. Symptoms persisting for more than three weeks after the diagnosis of COVID-19 fall into the category of post-COVID syndrome. The most common post-COVID symptoms include fatigue, dyspnea, olfactory and gustatory dysfunction, chest pain, myalgia, and sleep and mental disorders. The pathogenesis of post-COVID syndrome is multi-factorial. Underlying chronic, low grade inflammation has been theorized for pathogenesis. Available data shows conflicting results regarding the implication of inflammatory markers in full clinical spectrum and its long-term outcome.
