Single Low Dose of Human Recombinant Antithrombin (ATryn) has no Impact on Endotoxin-Induced Disseminated Intravascular Coagulation: An Experimental Randomized Open Label Controlled Study.

Background: Antithrombin (AT) III physiological levels are decreased during septic shock and supplementation therapy could therefore be beneficial.

Objective: We hypothesized that the use of recombinant human AT could reduce disseminated intravascular coagulation (DIC) occurrence.

Methods: We conducted a randomized open label controlled experimental study.

Human Recombinant Antithrombin (ATryn) Administration Improves Survival and Prevents Intravascular Coagulation After Intraportal Islet Transplantation in a Piglet Model.

Human islet transplantation is a viable treatment option for type 1 diabetes mellitus (T1DM). However, pancreatic islet inflammation after transplantation induced by innate immune responses is likely to hinder graft function. This is mediated by incompatibility between islets and the blood interface, known as instant blood-mediated inflammatory reaction (IBMIR).

IMPACT OF OBESITY ON ENDOTOXIN-INDUCED DISSEMINATED INTRAVASCULAR COAGULATION.

An early activation of coagulation and fibrinolysis occurs during sepsis, leading to the syndrome of disseminated intravascular coagulation (DIC). Obesity has been demonstrated to be a hypercoagulable and hypofibrinolytic state, but its impact on DIC has never been studied. In this study, we aimed to determine if obesity impairs DIC in an acute endotoxic shock model using minipigs.

Impact of endotoxin challenge in obese pigs.

Studies exploring the influence of obesity on septic shock remain limited and controversial. Pigs were chosen as a clinically relevant species, resembling to humans in various functions. We hypothesize obesity may impair porcine acute endotoxic shock.

Intravenous administration of activated protein C in Pseudomonas-induced lung injury: impact on lung fluid balance and the inflammatory response.

Background: Acute lung injury (ALI) induces a coagulation/fibrinolysis imbalance and leads to fibrin deposition. The protein C pathway is an important regulator of the coagulation system and reduces the inflammatory response. The aim of the study was to examine the effects of recombinant human activated protein C (rhAPC) in the early phase of Pseudomonas aeruginosa (Pa)-induced lung injury.

Massive alveolar thrombin activation in Pseudomonas aeruginosa-induced acute lung injury.

In acute lung injury (ALI), a coagulation/fibrinolysis imbalance leads to fibrin deposition, persistence of which contributes to fibrotic evolution. Our study evaluated the effects of early inhibition of coagulation in Pseudomonas aeruginosa (Pa)-induced ALI through the use of recombinant human antithrombin (rhAT). The study was conducted in vivo on a murine model of Pa-induced ALI.

Thrombotic thrombocytopenic purpura: medical and biological monitoring of six pregnancies.

Background: Thrombotic thrombocytopenic purpura (TTP) is a rare cause of severe thrombocytopenia in pregnancy.

Methods: Six pregnancies in five patients with TTP were followed prospectively over 5 years. Ultralarge von Willebrand factor (ULvWF) multimers and cleaving protease (cp) levels were measured.

Combined antithrombin and protein C supplementation in meningococcal purpura fulminans: a pharmacokinetic study.

Purpose: To document in patients with meningococcal purpura fulminans (PF), the effects of a combined supplementation with antithrombin (AT) and protein C (PC) plasma concentrates and to estimate the pharmacokinetics and dose requirements of each inhibitor.

Design: Retrospective study of 15 patients. SETTING.
