Protein C in adult patients with sepsis: from pathophysiology to monitoring and supplementation

Résumé fourni par la source

Protein C (PC) plays a crucial role in modulating inflammation and coagulation in sepsis. Its anticoagulant and cytoprotective properties are critical in mitigating sepsis-induced coagulopathy, which is associated with high mortality rates. In sepsis, low levels of PC are associated with an elevated risk of multiple organ dysfunction and increased mortality. Routine monitoring of PC levels is not widely implemented but appears relevant in selected populations, such as patients with purpura fulminans, sepsis-induced coagulopathy (SIC), disseminated intravascular coagulopathy (DIC) or hyperinflammatory septic shock phenotypes. Treatment with PC has been limited to PC concentrate approved for paediatric use in congenital PC deficiencies and purpura fulminans, while the efficacy of PC supplementation in sepsis remains a subject of debate. Considering the physiological significance of PC and its role in sepsis pathophysiology, additional studies are necessary to fully elucidate its therapeutic efficacy in specific clinical settings.
