Abstract
Coagulation disorders ranging from subtle changes in coagulation parameters to fatal disseminated intravascular coagulation (DIC) are common in septic patients. Coagulation activation is considered to be one of the most important factors contributing to multiple organ dysfunction syndrome (MODS) in sepsis. Anticoagulant therapy is, therefore, necessary to prevent MODS, but eligibility criteria remain controversial. Sepsis is a highly heterogeneous syndrome, which could explain the negative results of clinical studies on the treatment of sepsis. Recently, sepsis has been subdivided into several phenotypes with different therapeutic outcomes. At present, septic patients with dysfunctional coagulation expressed as increased D-dimer and fibrin/fibrinogen degradation products (FDPs) are considered to be candidates for anticoagulant therapy. In this review, we aimed to describe the features of different septic phenotypes. We also discuss factors that contribute to controversies in this area, and challenges in defining which septic phenotypes are good candidates for anticoagulant therapy.
