Summary

Severe sepsis and septic shock are the most severe forms of sepsis (which associates a systemic inflammatory response with infection). These are serious pathologies with a lethality estimated at almost 40% at 28 days (after the onset of sepsis). After a first pro-inflammatory phase, a second compensatory phase called Compensatory Anti-Inflammatory Response Syndrome (CARS) takes place quickly. Patients then show signs of immunosuppression and profound alterations in immune functions. It is during this phase that the vast majority of deaths occur, far from the onset of the shock, which is related to the inability of the immune system to eliminate the initial infectious agent and / or a greater susceptibility Important to develop secondary infections (nosocomial infection, latent virus reactivation ...). The CARS phase has been the subject of studies focusing on measuring the plasma concentration of anti-inflammatory cytokines (such as Interleukin (IL) -10), the percentage of regulatory T lymphocytes (Treg), Or the percentage of monocytic expression of HLA-DR in septic patients. The investigator proposes to carry out the first study on a newly described regulatory lymphocytic subpopulation: regulatory B lymphocytes (Breg) from a quantitative and functional point of view in severe septic states.
