In order to evaluate the diagnostic and prognostic value of thrombin-antithrombin complex（TAT）, α2-plasmin inhibitor-plasmin complex（PIC）, tissue plasminogen activator-inhibitor complex（tPAI·C） and thrombomodulin（TM） in sepsis-induced coagulopathy(SIC), hospitalized patients with sepsis were prospectively included. Plasma TAT, PIC, tPAI·C,TM levels within 24 h after sepsis diagnosis were detected by MCL60 chemiluminescence analyzer. According to the SIC score (≥4), they were divided into SIC group and non-SIC group, and ROC curve analysis was performed according to the biomarker test results.
Thrombin-antithrombin complex（TAT）, α2-plasmin inhibitor-plasmin complex（PIC）, tissue plasminogen activator-inhibitor complex（tPAI·C） and thrombomodulin（TM） can evaluate vascular endothelial damage, thrombin and plasminase activation, and have clinical significance in early diagnosis of DIC, thrombotic disease and monitoring of thrombolysis efficacy. However, whether these biomarkers can be used for early diagnosis of SIC is unclear.
In order to evaluate the diagnostic value of TAT, PIC, tPAI·C and TM in sepsis-induced coagulopathy(SIC), hospitalized patients with sepsis were prospectively included. Plasma TAT, PIC, tPAI·C,TM levels within 24 h after sepsis diagnosis were detected by MCL60 chemiluminescence analyzer. According to the SIC score (≥4), they were divided into SIC group and non-SIC group, and receiver operator characteristic（ROC） curve analysis was performed according to the biomarker test results. The area under the curve(AUC) was used to determine whether TAT, PIC, tPAI·C and TM could be used as biomarkers for SIC diagnosis. If AUC is between 0.7 and 0.9, this indicator has diagnostic value.
