Treatment with recombinant human activated protein C: One size does not fit all

Abstract

Protein C plays an important role in the coagulopathy associated with sepsis and probably also in the pathogenesis of sepsis-induced organ dysfunction. Plasma levels of protein C strongly correlate with clinical outcome in patients with severe sepsis. The RESPOND (Research Evaluating Serial Protein C Levels in Severe Sepsis Patients on Drotrecogin Alfa [Activated]) study shows that administration of recombinant human activated protein C in patients with severe sepsis with alternative dose regimens adjusted to plasma levels of protein C results in higher plasma levels of protein C. This may potentially translate to a better clinical outcome in patients with severe sepsis, although that was not directly shown in this trial. © 2011 BioMed Central Ltd.
