Markers of NETs were modestly elevated in patients compared to controls, and did not differ between patients that were or were not admitted to ICU, which may argue against a key role of NETs in the pathogenesis of COVID-19 associated sequelae as was suggested previously. Plasma CLT was higher in COVID-19 patients compared to healthy controls, but similar between patients on ICU and ward. TAT and PAP complex levels are strongly elevated in patients with COVID-19, indicating ongoing thrombin and plasmin generation in COVID-19 patients despite anticoagulation with LMWH. Taken together, our data confirm a hypercoagulable status of enhanced thrombin generating capacity, enhanced ex vivo clot formation likely related to hyperfibrinogenemia, and a decreased ex vivo fibrinolytic capacity in patients with COVID-19.
