Comparative Study of the Protein C Pathway in Septic and Non Septic Patients

This is a comparative study performed in 3 groups of patients/subjects: 30 severe sepsis patients, 30 non-septic patients with organ failure, 30 healthy subjects.

The only intervention is a venous blood sampling at the onset of the disease.

The purpose of the study is to compare the PC pathway and expression and inflammatory genes between the 3 groups. The main hypothesis is that systemic inflammatory response and exacerbated coagulation activation are non specific of an infection as a triggering event.
