The prevalence of Hemophilia B in the population is about one in 40,000; Hemophilia B represents about 15% of patients with hemophilia. [6] Many women carriers of the disease have no symptoms. [6] However, an estimated 10-25% of women carriers have mild symptoms; in rare cases, women may have moderate or severe symptoms. [6]
Haemophilia (British English), or hemophilia (American English) [6] (from Ancient Greek αἷμα (haîma) 'blood' and φιλία (philía) 'love of'), [7] is a mostly inherited genetic disorder that impairs the body's ability to make blood clots, a process needed to stop bleeding. [2][3] This results in people bleeding for a longer time after ...
Haemophilia C (also known as plasma thromboplastin antecedent (PTA) deficiency or Rosenthal syndrome) is a mild form of haemophilia affecting both sexes, due to factor XI deficiency. [ 4 ] It predominantly occurs in Ashkenazi Jews. It is the fourth most common coagulation disorder after von Willebrand's disease and haemophilia A and B.
Acquired haemophilia A (AHA) is a rare but potentially life-threatening bleeding disorder characterized by autoantibodies directed against coagulation factor VIII. These autoantibodies constitute the most common spontaneous inhibitor to any coagulation factor and may induce spontaneous bleeding in patients with no previous history of a bleeding ...
Haemophilia A (or hemophilia A) is a blood clotting disorder caused by a genetic deficiency in clotting factor VIII, thereby resulting in significant susceptibility to bleeding, both internally and externally. This condition occurs almost exclusively in males born to carrier mothers due to X-linked recessive inheritance.
Polycythemia (also known as polycythaemia) is a laboratory finding in which the hematocrit (the volume percentage of red blood cells in the blood) and/or hemoglobin concentration are increased in the blood. Polycythemia is sometimes called erythrocytosis, and there is significant overlap in the two findings, but the terms are not the same ...
Factor V Leiden (rs6025 or F5 p.R506Q[1]) is a variant (mutated form) of human factor V (one of several substances that helps blood clot), which causes an increase in blood clotting (hypercoagulability). Due to this mutation, protein C, an anticoagulant protein that normally inhibits the pro-clotting activity of factor V, is not able to bind ...
The condition is of importance in the differential diagnosis to other bleeding disorders, specifically the hemophilias: hemophilia A with a deficiency in factor VIII or antihemophilic globulin, hemophilia B with a deficiency in factor IX (Christmas disease), and hemophilia C with a deficiency in factor XI. Other rare forms of bleeding disorders ...
