Disseminated intravascular coagulation (DIC) often occurs with sepsis. A scoring system has been used for the diagnosis of DIC, but the system included at least 4 parameters. The purpose of this study was to propose a simple set of DIC criteria with coagulation-fibrinolysis markers (CFMs).
Patients with ≥2 signs of systemic inflammatory response syndrome and a quick Sequential Organ Failure Assessment score ≥ 2 points were investigated. All blood samples were collected on Days 0, 1, 3, and 7. Cutoff values of CFMs were calculated by receiver operating curve analysis. Positive predictive values (PPVs) and negative predictive values (NPVs) for the Japanese Association for Acute Medicine (JAAM) DIC criteria were evaluated by pairing the markers. Differences were analyzed by the Mann-Whitney U test, Kruskal-Wallis test, and the log-rank test.
A total of 107 patients were enrolled. The cutoff values of soluble fibrin (SF), protein C (PC), and plasminogen activator inhibitor (PAI)-1 were 48 μg/mL, 42%, and 71 ng/mL according to the International Society of Thrombosis and Hemostasis DIC criteria. The PPV of the severe SFxPC group was 100% for the JAAM DIC criteria, excluding Day 0.
Cutoff values of SF over 48 μg/mL and PC <42% could almost definitely identify JAAM DIC.
