Inflammatory response in relation to COVID-19 and other prothrombotic phenotypes

The haemostatic system acts in concert with inflammation, so that after inflammatory response various mediators activate the haemostatic system through endothelial dysfunction, platelet activation and coagulation promoting thrombosis, which is termed thromboinflammation. In this process, the inflammasome acquires special relevance;its stimulation promotes innate and adaptive immune responses. Inflamma some activation plays an important physiopathological role in several disorders with inflammatory and thrombotic phenomena. The role of thromboinflammation has become relevant in the COVID-19 pandemic, in which a cytokine storm has been described as one of the mechanisms responsible.

[Coagulopathy and thrombosis: similarities and differences among pathogenic coronaviruses].

One of the most significant negative prognostic factors in patients suffering from the disease caused by SARS-CoV-2 (COVID-19) is the development of coagulopathy, associated with abnormal laboratory findings, such as increased D-dimer, and venous thromboembolic complications, requiring thromboprophylactic strategies. The main clinical characteristics of COVID-19 patients are revised here as compared to other coronavirus infections, such as Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS), emphasizing clinical, diagnostic and therapeutic aspects.
