  • USE OF PROUROKINASE AND ITS VARIANTS AGAINST COAGULOPATHY CAUSED BY VIRUSES
    Publication number: 20220023397
    Abstract: The present invention relates to the technical field of bio-pharmaceuticals, and in particular relates to use of prourokinase and its variants against coagulopathy caused by viruses. It has been found that use of prophylactic doses of prourokinase or its variants in virus-infected patients can effectively prevent formation of thrombus and clots without increasing the risk of bleeding, thereby effectively preventing coagulopathy, such as disseminated intravascular coagulation, ST-segment elevation myocardial infarction, ischemic stroke, pulmonary embolism, deep veins thrombosis, and venous thromboembolism caused by viruses. When virus infection causes thrombosis in a patient, a thrombolytic therapy with a therapeutic dose of prourokinase or its variants can effectively dissolve the thrombus and lower the risk of death and disability.
