Abstract: Aims: Disseminated intravascular coagulation (DIC) is a common complication of heat stroke (HS) patients, and it is one of the important reasons leading to multiple organ failure and even death. The association between neutrophil extracellular traps (NETs) and DIC is unclear in HS mice. Methods and results: Here, HS was induced by the combination of hyperthermia (HT) and lipopolysaccharide (LPS). The DIC was evaluated by measuring prothrombin time (PT), D-dimer, thrombomodulin (TM), fibrinogen (FIB), and platelet (PLT). The expression of citrullinated-histone (CitH3) was analyzed by Western blotting. The formation of NETs was observed by immunofluorescence microscopy. The risk of HS-induced DIC was increased when HT was combined with LPS. The markers of NETs were significantly higher than those in the control group, and the NETs derived from HS promoted the development of DIC. DNase I improved coagulation dysfunction via the clearance of NETs caused by neutrophil aggregation. Conclusions: Degradation of NETs reduced the risk of developing DIC, and thus the survival rate of mice was improved. These results indicate that NETs may hold potential alternative therapeutic strategies for the treatment of DIC in HS patients.
