Factor IX deficiency was associated with a hemorrhagic disorder in a woman who previously had experienced postpartum hypotension resulting in Sheehan’s syndrome. There was no family history of Christmas disease, and other known causes of factor IX deficiency were excluded. Plasma levels of factor IX were partially corrected by therapy with thyroid hormones and completely restored to normal by t...
background: hemophilia b is an x-linked recessive coagulation disorder caused by factor ix deficiency. analysis of factor ix gene polymorphisms is considered the best approach for prenatal diagnosis and carrier detection of hemophilia b where the identification of gene mutation is not easily possible. objective: to study the frequency of three factor ix-linked restriction fragment length pol...
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 c...
The role of the factor IXa heparin-binding exosite in coagulation was assessed with mutations that enhance (R170A) or reduce (R233A) stability of the proteasefactor VIIIa A2 domain interaction. After tissue factor (TF) addition to reconstituted factor IX-deficient plasma, factor IX R170A supported a 2-fold increase in velocity index (slope) and peak thrombin concentration, whereas factor IX R23...

Prothrombin complex concentrates (PCC), licensed for the treatment of hemophilia B, are known to carry a significant risk of thromboembolic complications. Although the reasons for thrombogenicity are not completely understood, several manufacturers have developed purified factor IX concentrates that contain negligible amounts of the other vitamin K-dependent factors. To evaluate whether or not ...
Hemophilia B is an X-Iinked recessive bleeding disorder resulting from a deficiency of the coagulation factor IX (FIX) protein activity. a vitamin K-dependent serine protease active in both the intrinsic and extrinsic coagulation systems. DNA analyses of the factor IX gene in two unrelated patients with severe hemophilia B. with a IX coagulant activity <1 % and undetectable FIX antigen. detecte...
