- BACKGROUND: Puumala (PUUV) orthohantavirus causes hemorrhagic fever with renal syndrome (HFRS). HFRS patients have an activated coagulation system with increased risk of disseminated intravascular coagulation (DIC) and venous thromboembolism (VTE). The aim of the study was to determine if circulating extracellular vesicle tissue factor (EVTF) activity levels associates with DIC and VTE (grouped as intravascular coagulation) in HFRS patients.METHODS: Longitudinal samples were collected from 88 HFRS patients. Patients were stratified into groups of those with intravascular coagulation (n=27) and those who did not (n=61). We measured levels of circulating EVTF activity, fibrinogen, activated partial prothrombin time, prothrombin time international normalized ratio, D-dimer, tissue plasminogen activator (tPA), plasminogen activator inhibitor 1 (PAI-1) and platelets.RESULTS: Plasma EVTF activity was transiently increased during HFRS. Levels of EVTF activity significantly associated with plasma tPA and PAI-1, suggesting endothelial cells as a potential source. Patients with intravascular coagulation had significantly higher peak EVTF activity levels compared to those who did not. The peak EVTF activity value predicting intravascular coagulation was 0.51 ng/L with 63% sensitivity and 61% specificity with AUC 0.63 (95% CI 0.51 - 0.76), p-value 0.046.CONCLUSIONS: Increased circulating EVTF activity during HFRS is associated with intravascular coagulation.
