Prothrombin complex concentrates (PCCs) are widely administered for emergency oral anticoagulation reversal and for coagulation defects in liver disease. Pharmacokinetic data may help to optimize treatment. The objective of this study was to characterize the pharmacokinetics of a PCC (Beriplex P/N) containing coagulation factors II (FII), VII (FVII), IX (FIX) and X (FX) and anticoagulant protei...

introduction: normal homeostasis system has several inhibitor mechanisms in front of the amplifier’s natural clotting enzyme to prevent fibrin clots in the vessels. the main inhibitors of coagulation pathway are antithrombin (at), protein c and protein s. patients with hereditary deficiency of coagulation inhibitors are susceptible to venous thromboembolism (vte). one of the major clinical mani...

OBJECTIVE To evaluate the efficacy of loop electrosurgical excision procedure (LEEP) combined with cold coagulation for treating cervical intraepithelial neoplasia (CIN). METHODS We reviewed clinic-pathologic data of 498 patients treated with LEEP alone (n=354), and LEEP combined with cold coagulation (n=144) between January 2000 and December 2011. After LEEP, we followed up all patients by u...

Under physiological conditions, the coagulation system is designed to maintain the circulating blood in a fluid state, but act towards restoration of vascular integrity by rapid clot formation after vessel injury. Historically, the coagulation cascade was divided into 2 major systems: the extrinsic and the intrinsic pathway (Figure 1).1 The tissue factor (TF)factor VII/VIIa (FVII/FVIIa) complex...

Perioperative dilutional coagulopathy is a major coagulation disorder during adult and pediatric surgery. Although the main underlying mechanisms are comparable, data of the development and management of dilutional coagulopathy in children are scarce. Observational data showed that intraoperative coagulation disorders mainly based on complex disturbances of clot firmness including acquired fibr...

New Zealand white rabbits were given 30 ml of goat serum intravenously. This procedure resulted in an immediate decrease in platelet count, fibrinogen, and levels of coagulation factors II, V, VII, and X, due to consumption coagulopathy. These factors returned toward baseline levels approximately 12 hr after the injection. Plasma from rabbits who had received goat serum 48 hr previously (donor ...

BACKGROUND High levels of blood lipids have been associated with high levels of coagulation factors. We investigated whether blood lipids influence the results of global coagulation tests, including prothrombin time (PT), activated partial thromboplastin time (aPTT), and thrombin generation assay (TGA). METHODS PT, aPTT, and TGA, along with procoagulant and anticoagulant factors, were measure...

Many anticoagulant drugs inhibiting proteins of the coagulation cascade have been developed. The main targets of anticoagulant drugs are thrombin and factor Xa; inhibiting these factors delays thrombus growth, thus preventing thrombosis while increasing bleeding risk. A balance between thrombosis and bleeding is ensured in the 'therapeutic window' of the anticoagulant drug concentration range. ...
