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 ...
Recombinant factor VIIa (rfVIIa) is a form of blood factor VII that has been manufactured via recombinant technology. [4] [5] It is administered via an injection into a vein. [6] [4] [5] It is used to treat bleeding episodes in people who have acquired haemophilia, among other indications. [7] There are several disimilar forms, and biosimilars ...

The type of haemophilia known as parahaemophilia is a mild and rare form and is due to a deficiency in factor V. This type can be inherited or acquired. [10] A non-genetic form of haemophilia is caused by autoantibodies against factor VIII and so is known as acquired haemophilia A. [15]
Joint capsule. Haemophilia A's phenotype has a quite wide range of symptoms encompassing both internal and external bleeding episodes. Individuals with more severe haemophilia tend to experience more intense and frequent bleeding, whereas those with mild haemophilia typically exhibit milder symptoms unless subjected to surgical procedures or significant trauma.
Related annual fundraising campaigns are called Red Tie Campaigns. [10] The NBDF also hosts comedy fundraisers to support its efforts. [8] The organization also organizes an annual national Unite Day event to encourage community participation in the foundation's mission. [10] The day includes a Unite for Bleeding Disorders Walk.

This interaction sets off a chain of additional chemical reactions that form a blood clot. [8] Factor VIII participates in blood coagulation; it is a cofactor for factor IXa, which, in the presence of Ca 2+ and phospholipids, forms a complex that converts factor X to the activated form Xa. The factor VIII gene produces two alternatively spliced ...
The International Society on Thrombosis and Haemostasis (ISTH) is a not-for-profit global membership organization of specialists in the field of blood coagulation and its disorders, such as thrombosis and hemophilia. It was founded in 1954 as the International Committee on Thrombosis and Haemostasis (ICTH).
