Abstract
OBJECTIVE
To consider the appropriateness of protein C levels as a prognostic indicator for sepsis and related diseases.
DATA SOURCES/STUDY SELECTION
Published research and review articles related to protein C deficiency in patients with sepsis and related diseases.
DATA EXTRACTION AND SYNTHESIS
All applicable data were extracted, and relevant literature was cited to support factual statements in the text. The protein C pathway represents one of the major regulatory systems of hemostasis, exhibiting antithrombotic, profibrinolytic, and anti-inflammatory properties. Numerous studies have shown that acquired protein C deficiency is prevalent in the majority of septic patients (>85%) and is associated with increased morbidity and mortality in patients with severe sepsis and septic shock. This deficiency in protein C is not simply a transient marker for sepsis, but parallels the progress of the disease. In addition, protein C deficiency occurs in the presence of a wide range of pathogens and develops early in the disease process.
CONCLUSIONS
A review of the relevant literature suggests that protein C levels may serve as a useful prognostic indicator of outcome in sepsis and related diseases.
