Pro-inflammatory Role of Blood Platelets in Critically Ill Patients With Septic Shock. — PLAQSIS  

Septic Shock Clinical Trial

Official title:
Pro-inflammatory Role of Blood Platelets in Critically Ill Patients With Septic Shock: an Observational Study.

Clinical Trial Summary

Blood platelets play a major role in the inflammatory response. A dysregulation of platelets activation may be one of the contributors to tissue damage in critically ill patients with septic shock. The main objective of this study is to compare platelet activation markers levels (including plasma concentration in CD154, beta thromboglobulin, platelet factor 4, platelet microparticles, soluble CD62, RANTES, GRO-alpha and HMGB-1) at the early phase of a septic shock and a systemic inflammatory response syndrome (SIRS).

Clinical Trial Description

Sepsis is defined as life-threatening organ dysfunction due to dysregulated host response to infection which can lead to many failures of vital organs (kidneys, lungs, liver) in critically ill patients. It is accompanied at an early phase by both a proinflammatory and procoagulant state generating many platelet activators. Given their essential role in the inflammatory response, a dysregulation of platelets activation may be one of the contributors to tissue damage. To determine if platelet activation contribute to deregulation of the inflammatory response of the host in sepsis, the main objective of this study is to compare platelet activation markers levels of patients with septic shock and after major surgery. Plasma concentration in CD154, beta thromboglobulin, platelet factor 4, platelet microparticles, soluble CD62, RANTES, GRO-alpha, HMGB-1, monocyte Dnases signal, circulating free DNA and DNase1 and DNase1L3 activities will be studied and compared at inclusion (Day 0), Day 1 and Day 5. ;
