We investigated the activation of the nonenzymatic protein cofactors factor VIII and factor V in plasma when coagulation was initiated by thromboplastin. With sensitive bioassays, we were able to measure specifically the generation of activated factor VIII and activated factor V in plasma. Our results showed that when plasma was triggered with a relatively high concentration of thromboplastin, ...
Hemophilia A and B are X-linked diseases that predominantly affect male patients. Patients can develop coagulation factor inhibitors, which exponentially increases the treatment cost. However, the prevalence of factor VIII and IX inhibitors in Saudi Arabia is unclear.This study aimed to determine the Saudi prevalence of factor VIII and IX inhibitors.This 4-year, 7-center, cross-sectional study ...
We have studied the modifications in the multimeric composition of plasma factor VIII/von Willebrand factor and the bleeding time response following administration of 1-Deamino-[8-D-arginine]-Vasopressin (DDAVP) to patients with different subtypes of von Willebrand's disease. In type I, all multimers were present in plasma in the resting state, though they were decreased in concentration. Admin...
Transfusion of blood products from an infected person with AIDS, is meant to infect recipient. Blood Products such as whole blood, red blood cells, platelets, plasma, frozen blood precipitate, factor VIII, factor IX, can be infected with HIV. Transmissions from blood factors can be seen in plasma from thousands of donors that were collected in a container and were used to treat hemophilia. Bloo...
Circulating antibodies to factor VIII (anti-VIII, "inhibitors") occurring in patients with hemophilia neutralize porcine factor VIII less readily than human factor VIII in vitro. Over an 18-mo period, 8 patients with anti-VIII were treated with 45 courses (297 infusions) of polyelectrolyte-fractionated porcine factor VIII concentrate (PE porcine VIII). Where no anti-PE porcine VIII was detectab...
Recombinant factor VIII and factor IX concentrates, human-plasma–derived albumin, and samples from previously untreated patients with hemophilia were examined for the presence of TT virus (TTV) by using polymerase chain reaction testing. Blood samples from the patients were obtained prospectively before and every 3 to 6 months after therapy was begun. TTV was detected in 23.5% of the recombinan...
BACKGROUND: Combined factor V and VIII deficiency (CF5F8D) is a rare autosomal recessive disorder, with an estimated prevalence of about 1:100,000 in the Jewish population. Affected individuals have between 5 and 30% of normal levels of factor V and VIII, whereas the levels of other plasma proteins are not altered. This bleeding disorder has been treated by replacement therapy with plasma infus...

Background Bone marrow transplantation (BMT)is nowadays used in various hematological disorders including leukemias. Hemophilia A & B are sex linked bleeding disorders in which there are various genetic abnormalities in factor VIII & IX genes. Among various hematological disorders, bleeding disorders mainly hemophilia in now widely treated using plasma derived and recombinant factor VIII & IX ...
