Prothrombin complex concentrates (PCCs) have been associated with a possible risk of thromboembolic complications, potentially attributable to an increased ratio of the plasma concentration of factor II (FII) to antithrombin (AT). We developed a mathematical model to examine the relationship between amounts of PCC or therapeutic plasma administered, and plasma levels of FII and AT. The model sh...

Since 1981, the number of factor VIII units to infuse into patients with hemophilia A in order to achieve adequate circulating factor VIII levels has been calculated using the formula: [body weight(kg)× desired factor VIII increase(%)]/2, assuming a factor VIII recovery value of 2 for all patients. This study's aim was to evaluate the impact of several morphometric parameters and various coagul...

BACKGROUND Prothrombin complex concentrates (PCCs), which contain different coagulation proteins, are attractive alternatives to the standard methods to treat dilution-induced (and, generally, traumatic) coagulopathy. We investigated the ability of a novel PCC composition to restore normal thrombin generation in diluted blood. The performance of the proposed PCC composition (coagulation factors...

Background: Hemophilia B is a bleeding disorder with a recessive X-linked inheritance pattern, in which the infected individuals have low levels of factor IX in their plasma. Affected individuals may have bleeding episodes after trauma or spontaneously considering the plasma level of factor IX. In order to prevent these episodes and to control bleeding, they should use coagulation factor concen...

Over the past forty years the availability of coagulation factor replacement therapy has greatly contributed to the improved care of people with hemophilia. Following the blood-borne viral infections in the late 1970s and early 1980, caused by coagulation factor concentrates manufactured using non-virally inactivated pooled plasma, the need for safer treatment became crucial to the hemophilia c...

  Background: Factor VII concentrates are used in patients with congenital or acquired factor VII deficiency or treatment of hemophilia patients with inhibitors. In this research, immunoaffinity chromatography was used to purify factor VII from prothrombin complex (Prothrombin-Proconvertin-Stuart Factor-Antihemophilic Factor B or PPSB) which contains coagulation factors II, VII, IX and X. The a...

When plasma is separated or recovered from a blood donation or when plasma is collected by plasmapheresis the end result is not just a fluid which can be used in the treatment of many medical conditions but a raw material which can be used for the production of specific life saving or life enhancing medications for a variety of conditions. These conditions include Haemophilia A and Haemophilia ...

in their report Inefficacy of fresh frozen plasma in the treatment of L-asparaginase induced coagulation factor deficiencies during ALL induction therapy, Nowak-Göttl and coll. reported that the prophylactic administration of fresh frozen plasma in acute lymphoblastic leukemia (ALL) patients treated with L-asparaginase (L-Ase) is of no use in correcting the hemostatic imbalance. In fact, they o...

As fresh frozen plasma (FFP) loses coagulation factor activity during the production process, FFP therapy may not be feasible to completely replenish coagulation factor concentrations in a clinical setting. The aim of this study was to describe the results of early replacement coagulation factors with FFP in a simplified and idealized in vitro model of dilution. Six ml of whole blood drawn from...
