Abstract:Protein C zymogen did not improve clinically relevant outcomes in severe sepsis and septic shock adult patients. Given its high cost and the potential increase in mortality, the use of this drug in adult patients should be discouraged.
“…The importance of the thrombomodulin/activated protein C system in preserving blood clotting homeostasis and the functional integrity of microcirculation has been largely recognized, and it has been shown that this system is compromised in DIC caused by sepsis . Although it was assumed that the reconstitution of the protein C/thrombomodulin system could alleviate the symptoms of sepsis‐related DIC, the use of rhAPC failed to improve clinical outcomes . Thrombomodulin has been used in patients with sepsis‐related DIC, but definite conclusions about its clinical efficacy are awaited, with the completion of a randomized controlled trial (phase III study) which is underway .…”

An ongoing endothelial/hemostatic disorder was established during sepsis, observed even at clinical improvement. Among the variables tested, protein C and ADAMTS-13 change were associated with outcome.

“…The anticoagulant effect of aPC is well defined, however its use in microangiopathic patients, such as in sepsis, did not improve outcome. 44 , 45 Third crosstalk is at the level of fibrinolysis where aPC has been suggested to neutralize fibrinolysis inhibitors TAFI and PAI-1 resulting in the activation of the fibrinolysis. 46 Decreased levels of aPC might in turn limit the fibrinolytic response.…”
Recent evidence is focusing on the presence of a hypercoagulable state with development of both venous and arterial thromboembolic complications in patients infected with SARS-CoV-2. The ongoing activation of coagulation related to the severity of the illness is further characterized by thrombotic microangiopathy and endotheliitis. These microangiopathic changes cannot be classified as classical disseminated intravascular coagulation (DIC). In this short review we describe the interaction between coagulation and inflammation with focus on the possible mechanisms that might be involved in SARS-CoV-2 infection associated coagulopathy in the critically ill.
“…An Italian single-centre RCT (n = 38) assessed use of protein C zymogen vs. placebo in high-risk ICU patients with severe sepsis/septic shock [15]. The study was stopped early because of safety issues: the composite primary outcome of prolonged ICU stay and 30-day mortality was 79 vs. 67%, in-ICU mortality was 79 vs. 39%, and 30-day mortality was 68 vs 39% in the protein C zymogen group vs the placebo group.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
