Impaired coagulation factor synthesis in cirrhosis causes a reduction of most pro- and anticoagulant factors. Cirrhosis patients show no clear bleeding or thrombotic phenotype, although they are at risk for both types of hemostatic event. Thrombin generation (TG) is a global coagulation test and its outcome depends on underlying pro- and anticoagulant processes (prothrombin conversion and throm...

Inherited deficiencies of plasma proteins involved in blood coagulation generally lead to lifelong bleeding disorders. The severity of these disorders is generally inversely proportional to the degree of factor deficiency. Among all the autosomal recessive rare bleeding disorders, which include afibrinogenaemia, factor (F) II, FV, FV + VIII, FVII, FX, FXI, FXIII, the combined deficiency of coag...

Treatment of dairy white wastewater (WW) by reverse osmosis (RO) is usually performed to generate process water and reclaim components for their valorization. For this study, a mixture pasteurized milk WW from plant was concentrated RO achieve protein concentration similar that skimmed milk. Retentates, which are WW, were used in the preparation cheese The effect using model evaluated on (1) so...

Trauma-induced coagulopathy (TIC) is a frequent complication of severely injured patients. The etiology of TIC is complex. Contributing factors include overwhelming generation of thrombin and activated protein C, consumption of coagulation factors and platelets, hyperfibrinolysis, and dilution of clotting factors through administration of fluids. In addition, hypothermia and shock-associated me...

Over-anticoagulation is a common problem with warfarin therapy and can lead to major or life-threatening bleeding. The goal of urgent warfarin reversal is to elevate or replace vitamin K-dependent clotting factors. In the United States, fresh frozen plasma (FFP) is considered the standard of care for warfarin reversal. Prothrombin complex concentrates (PCCs) offer an alternative to FFP for rapi...

Oral direct inhibitors of thrombin and activated factor Xa are approved as new anticoagulant drugs. In contrast to vitamin K antagonists (VKA) and heparins, the new agents have single targets in the coagulation cascade and more predictable pharmacokinetics, but they lack validated and available antidotes. Unlike VKA, they do not require routine monitoring of coagulation. However, the measuremen...

Prothrombin complex concentrates (PCCs) are purified drug products with hemostatic activity derived from a plasma pool. Today, PCCs contain a given and proportional amount of four non-activated vitamin K-dependent coagulation factors (II, VII, IX, and X), a variable amount of anticoagulant proteins (proteins C and S, and in some antithrombin) and low-dose heparin. In some countries PCC products...

conclusions the case was fully investigated and diagnosed as a case with factor xiii deficiency causing such uncontrolled bleeding after extraction of a tooth. introduction factor xiii deficiency is a relatively rare hereditary bleeding disorder, which is usually found during infancy or early childhood. this condition may involve both genders within different races in an equal manner. its incid...

BACKGROUND Myelofibrosis and acquired hemophilia A is a rare association. To the best of our knowledge only one case of myelofibrosis and acquired hemophilia A has been previously described. CASE PRESENTATION A 66-year-old Caucasian man diagnosed with myelofibrosis evolving in acute myeloid leukemia was referred to us for postoperative bleeding. Hemostatic studies showed prolonged activated p...

Perfusionists should be able to verify diagnosis and recognize the forms of von Wille brand disease (vWD) which may require specific coagulation management during open heart procedures. von Willebrand factor (vWF) plays two distinct and important roles in clot formation subsequent to vascular injury. First, it promotes platelet binding to subendothelial surfaces and other platelets (platelet ag...
