Early detection and markers of sepsis.
In vitro and animal models of sepsis have provided a template for studies of the pathogenesis of sepsis in patients at risk for and with the syndrome. Numerous potential markers have been identified in these models and then looked for in patients. No single marker or combination of markers convincingly identifies sepsis, predicts the development of sepsis, predicts the development of complications of sepsis, or predicts mortality. As discussed, the clinical studies have been complicated by many confounding variables, including the lack of adherence to rigorous definitions, differences in assay methods, differences in timing of the studies, and differences in outcome variables analyzed. In spite of the limitations, the studies have been critical in helping determine the pathogenesis of sepsis in humans. As new mediators and modulators of inflammation are identified, it will be important to study their role as markers, individually and in combination, in human disease.
