Abstract

The invention provides a group of markers for predicting cytokine release syndrome and thrombostorm of 2019 coronavirus, application of the markers, a kit and a preparation method of the kit, and belongs to the technical field of biological medicines. The markers provided by the invention are respectively VEGFD, TNF-alpha, SCF, LIF, IL-2, IL-4, IL-6, IL-8, IL-10, IL-15 , IL-17A, IL-18, IL-1beta and IFN-gamma. The kit for predicting the cytokine release syndrome and thrombus storm of the 2019 coronavirus disease (COVED19) by utilizing the group of markers of VEGFD, TNF-alpha, SCF, LIF, IL-2, IL-4, IL-6, IL-8, IL-10, IL-15 , IL-17A, IL-18, IL-1beta and IFN-gamma or the kit prepared from the markers has the advantages of rapid and accurate detection, low cost and the like.

Description

Technical field [0001] The invention belongs to the technical field of biomedicine, and particularly relates to a group of markers for predicting cytokine release syndrome and thrombus storm of coronavirus disease (COVID-19) in 2019, applications thereof, a kit and a preparation method of the kit. technical background [0002] Among the 2019 patients with coronavirus disease (COVID-19), about 15% of COVID-19 patients developed severe cases, and 5% to 6% of them developed critical cases. The mortality of COVID-19 critically ill patients is significantly higher than that of critically ill patients. It is reported that "cytokine release syndrome and thrombotic storm" is related to the disease criticality and lethality of COVID-19 patients. Therefore, it is urgent to develop markers that can effectively predict "cytokine release syndrome and thrombus storm" at an early stage to distinguish critical patients from critical patients, so as to formulate effective treatment plans in advan...
