Objective To evaluate the value of molecular markers of thrombine-antithrombin complex(TAT),soluble thrombomodulin(sTM),tissue-plasminogen activator-inhibitor complex(t-PAIC)in the early diagnosis of disseminated intravascular coagulation(DIC)in sepsis patients.Methods Thirty patients diagnosed with DIC secondary to hemoinfect-induced sepsis were selected as the DIC group in the intensive care unit(ICU)of the First Hospital of Lanzhou University from July to September 2023.Thirty patients with sepsis caused by bloodstream infection without DIC were randomly selected as the sepsis group.General data and procalcitonin(PCT),platelet count(PLT),white blood cell count(WBC),the levels of traditional clotting indexes activated partial thromboplastin time(APTT),prothrombin time(PT),fibrinogen(Fib),D-dimer and new clotting indexes(TM,TAT,t-PAIC)were collected.The indicators with statistical significance in univariate analysis were included in multivariate Logistic regression analysis to screen the independent risk factors for DIC in sepsis patients.Receiver operator characteristic curve(ROC curve)was drawn to analyze the diagnostic value of TM,TAT,t-PAIC and their combination in the occurrence of DIC in sepsis patients.Results A total of 60 patients with sepsis were included.There was no significant difference in gender,age,PCT,PLT and WBC between the DIC group and the sepsis group.In terms of traditional coagulation indexes,the PT level in sepsis DIC group was significantly lower than that in sepsis group,and the Fib level was significantly higher than that in sepsis group(both P<0.05).There were no statistically significant differences in APTT and D-dimer levels between the two groups.In terms of new coagulation indexes,TAT,sTM and t-PAIC levels in sepsis DIC group were significantly higher than those in sepsis group(all P<0.05).Multivariate Logistic regression analysis showed that TAT,sTM were independent risk factors for DIC in sepsis patients(both P<0.05).ROC curve analysis showed that TAT,sTM,t-PAIC combined detection had certain value in diagnosis of DIC in sepsis patients,area under the curve(AUC)was 0.735;when the cut-off value was 0.73,the sensitivity was 100.0%and specificity was 43.3%.Conclusion TAT,sTM and t-PAIC could help to predict DIC in sepsis.
