Summary
Acquired haemophilia (AH) is a rare bleeding disorder caused by autoantibodies against factor VIII (FVIII). Immunosuppressive therapy often eliminates these antibodies, restoring normal FVIII activity and improving patient outcomes.
Area of Science:
- Hematology
- Immunology
Context:
- Acquired haemophilia (AH) is a rare but severe bleeding disorder.
- It arises from autoantibodies inhibiting coagulation factor VIII (FVIII) activity.
- While autoimmune diseases, cancer, and puerperium are associated triggers, many cases are idiopathic.
Purpose:
- To outline the characteristics, diagnosis, and management of acquired haemophilia.
- To highlight the role of autoantibodies in FVIII deficiency.
- To discuss treatment strategies for bleeding episodes and antibody eradication.
Summary:
- AH presents with spontaneous or post-traumatic bleeding, particularly subcutaneous and mucosal hemorrhages.
- Diagnostic hallmarks include prolonged activated partial thromboplastin time with normal other hemostatic tests.
- Confirmation requires quantifying FVIII-neutralizing antibodies.
Impact:
- Bleeding is managed with factor concentrates (activated prothrombin complex or recombinant activated factor VII).
- Immunosuppressive agents are effective in eliminating autoantibodies and restoring FVIII levels in most patients.
- Effective management strategies improve prognosis for individuals with acquired haemophilia.

01:24Disorders of Hemostasis
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

02:45Blood Transfusion and Agglutination
Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:30Anticoagulant Drugs: Low-Molecular-Weight Heparins
Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
01:05Introduction to Hemostasis
Hemostasis is a complex physiological process that prevents excessive bleeding when a blood vessel is injured. It's crucial for maintaining the integrity of the circulatory system, as it ensures that our blood remains fluid while still within the vascular network and yet clots to prevent blood loss upon vessel injury.
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized, and...

01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
