The emerging SARS-COV2 virus has shed new light on the cross-talk between the immune and the hemostatic system. Pathophysiologically in COVID-19 infection the thrombo-inflammatory process is initiated by the host's exaggerated systemic inflammatory response, also called dysregulated immune response that activates both the inflammatory and the coagulation cascade directly by inflammatory mediators and indirectly by causing endothelial cell injury. These mechanisms altogether contribute to the imbalance of the hemostasis that is characterized by a procoagulant state.~In this multicenter prospective observational study, we aim to evaluate the dynamic change in coagulation as a result of immunomodulation by interleukin-6 antagonists in critically ill COVID-19 patients. We will assess the hemostatic system by a viscoelastic hemostasis assay (Clotpro, Haemonetics Corporation, Boston). Furthermore, we try to draw attention to possible associations between endothelial cell injury, inflammation, and coagulation. To compare these parameters we will draw blood for analysis before administration of IL-6 antagonist then 24h after, 48h after, and 7 days after.
