Brief Summary:
Sepsis induces hemostatic disorders due to the exessive or inappropriate activation of inflammation, which could lead either to hypercoagulability or hypocoagulability. It is currently not possible to determine the hemostatic status of a given patient. This instability of hemostatic system is not revealed by classical tests. Thus, a better characterization of hemostatic status could certainly improve patient care. This study aims at characterizing disorders of coagulation and fibrinolysis using "global" tests such as thrombin generation test or coagulolytic test. Furthermore, the association with biological markers of interest (such as microparticles, neutrophil elastase or histones) will be evaluated.

Primary Outcome Measures :
  1. Changes in endogenous thrombin potential as assessed by thrombin generation test [ Time Frame: 48 hours ]
    thrombin generation will be measured using CAT method (fluorescence) in plasma from patients within 48 hours. Endogenous thrombin potential is defined as the area under the thrombin generation curve and will be compared with values obtained in healthy subjects


Secondary Outcome Measures :
  1. Changes in Thrombin peak as assessed by thrombin generation test [ Time Frame: 48 hours ]
    thrombin generation will be measured using CAT method (fluorescence) in plasma from patients within 48 hours. Thrombin peak is defined as the highest thrombin concentration derived from the thrombin generation curve and will be compared with values obtained in healthy subjects.

  2. Changes in clot lysis time as assessed by clot lysis assay [ Time Frame: 48 hours ]
    Clot lysis assay will, be performed in plasma from patients and will be compared with those obtained in healthy subjects.

  3. Correlation of neutrophil elastase with changes in endogenous thrombin potential [ Time Frame: 48 hours ]
    Neutrophil elastase will be measured in plasma from patients.

  4. Correlation of cell-derived microparticles with changes in endogenous thrombin potential [ Time Frame: 48 hours ]
    microparticles derived from leukocytes, erythrocytes, platelets and endothelial cells will be measured in plasma from patients by flow cytometry.

  5. Correlation of circulating histones with changes in endogenous thrombin potential [ Time Frame: 48 hours ]
    Circulating histones will be measured in plasma from patients
