Acquired haemophilia A (AHA) is a rare, serious bleeding disorder most often encountered in elderly patients. The mainstay of haemostatic management is with bypassing agents (BPAs) including recombinant activated factor VII (rFVIIa) and activated prothrombin complex concentrates (aPCCs). Their major limitation is incomplete efficacy, potential risk for thrombosis and the lack of routine laboratory assays for monitoring treatment response. Plasma-derived porcine FVIII (pd-pFVIII, Hyate C(®)), first used in the 1950s for the management of congenital haemophilia, has sufficient sequence homology to be haemostatic in humans, but the lack of complete homology facilitates efficacy even in the presence of human allo- and autoantibodies against human FVIII (hFVIII)...

AIM: There is a paucity of data on the clinical presentation and management of cancer patients with acquired haemophilia (AH), we here report a systematic literature review on acquired haemophilia in the context of cancer. METHODS: Treatment outcomes of AH were defined as complete response (CR), partial response (PR) or no response (NR), based on inhibitor eradication, coagulation factor VIII levels and bleeding control. Reported deaths were either related to cancer or bleeding...

Acquired haemophilia A (AHA) due to autoantibodies against Factor VIII (FVIII) is a rare disease associated with severe bleeding. Since diffuse cutaneous hematomas and ecchymoses are the main clinical signs of this condition, dermatologists should be aware about this disease. Here, we present a case of AHA in a patient with systemic lupus erythematosus (SLE). This article is protected by copyright. All rights reserved.

Acquired coagulation factor VIII inhibitor leads to a rare disease i.e., acquired haemophilia which is idiopathic in majority of cases and is seen with autoimmune diseases, haematologic and solid tumours, infections, in the post-partum period and also with certain long-term use of drugs like penicillin and its derivatives, phenytoin, sulfa antibiotics, chloramphenicol, methyldopa, chlorpromazine, levodopa, interferon-α, fludarabine, clopidogrel. We report a case here, with acquired Factor VIII (FVIII) inhibitor acquisition which presented with delayed wound healing as a result of protracted bleeding into the wound...

Acquired haemophilia A (AHA) is a bleeding disorder that results from autoantibodies against factor VIII (FVIII). A 70-year-old man with a history of interstitial lung disease presented with spontaneous bleeding into his thigh. He had undetectable FVIII levels and a high-titre FVIII inhibitor (>2000ââ'¬â€°Bethesda units/mL) and was diagnosed with AHA. He had several relapses, required multiple haemostatic and immunosuppressive treatments but eventually achieved a stable remission after 2ââ'¬â€°years of therapy...

INTRODUCTION: Central venous access devices facilitate home treatment in boys with haemophilia. These are usually fully implanted lines, referred to as ports. Caregivers are taught to manage the port using sterile techniques and maintaining patency by flushing with saline or heparin solution. National and international guidelines for the home care of ports are lacking. AIM: To evaluate if infection or occlusion rates differ between home care regimens used for ports in children with haemophilia...

Diabetes mellitus encompasses a group of highly prevalent carbohydrate metabolic disorders with an increasing incidence. Some subtypes are thought to be associated with other immune-mediated diseases. Acquired haemophilia on the other hand is a quite rare autoimmune disease that is thought to be secondary to the emergence of inhibiting anticoagulation factor VIII antibodies (inhibitors) in patients with previously normal haemostatic function. More recently, numerous different diseases have been associated with acquired haemophilia namely immune-mediated diseases, drugs and solid and haematologic neoplasms...

The development of circulating autoantibodies able to inhibit some coagulation proteins induces severe or even life-threatening bleeding. This disorder is called acquired haemophilia. This is a rare disease, although its impact may be underestimated because of the lack of records, the lack of knowledge by many specialists, the complexity of the laboratory diagnosis and, finally, because of the fulminant clinical presentation that often precludes diagnosis. Several studies established that mortality ranges between 9 and 33%...

INTRODUCTION: Recombinant factor VIIa (rFVIIa) is recommended in Europe at standard (3 × 90 μg kg(-1) ) or high (1 × 270 μg kg(-1) ) doses. When granting the license for the high dose, the European Medicines Agency (EMA) requested postmarketing surveillance for thrombosis. This was conducted by the United Kingdom National Haemophilia Database (NHD) on behalf of Novo Nordisk and the EMA. AIM: To assess the use and safety of rFVIIa utilizing prospective data collected by the NHD (1 January 2008 to 30 June 2011)...

Acquired haemophilia is a rare disease in which bleeding is more severe than in hereditary haemophilia and usually occurs in the soft tissues, the gastrointestinal tract, or the mucous membranes. There have been only a few presentations of spontaneous sublingual haematoma in acquired haemophilia, but prompt management of the airway and identification of the underlying cause was crucial in all.

An African-American man aged 65 years with multiple malignancies in remission was admitted for small bowel obstruction. He was treated with laparotomy following failure of conservative management. Postoperatively, he developed intra-abdominal bleed, which persisted, despite surgical haematoma evacuation. Further haematological workup revealed isolated prolongation of activated partial thromboplastin time (aPTT) with reduced factor VIII (FVIII) activity and raised FVIII inhibitor titre. Assuming acquired haemophilia A (AHA), FVIII inhibitor bypassing activity and corticosteroids were started with subsequent resolution of the bleeding from the surgical site...

A cornerstone of the management of Acquired Haemophilia A (AHA) involves inhibitor eradication. First line immunosuppressive agents are usually steroids, either alone or in combination with cyclophosphamide. We present the use of Rituximab, cyclophosphamide, vincristine and prednisolone (RCVP) combination as immunosuppressant in AHA in a small cohort of patients in order to control their symptoms and eradicate inhibitors. This was a retrospective analysis of all AHA patients treated at the Northern Ireland Haemophilia centre over a six year period...

A 72-year-old man, on treatment for prostate cancer, attended the emergency department with his 2nd episode of spontaneous extensive bruising and haematomas. His first presentation was 2 months prior but this was thought to be because of his aspirin and he improved when aspirin was discontinued. On this occasion aspirin had been restarted 7 days before he developed his symptoms. His blood investigation was significant for a much raised activated partial thromboplastin time (aPTT). On his 3rd day of admission he deteriorated clinically with a drastic drop in his haemoglobin and worsening tense haematomas...

BACKGROUND: Acquired haemophilia A is caused by the development of an autoantibody to factor VIII in a person with previously normal haemostasis. The most common clinical presentation in hereditary haemophilia is intra-articular bleeding. In contrast, acquired haemophilia more commonly presents with skin, soft tissue and mucosal haemorrhages. METHODS: We present a case of a patient with idiopathic acquired haemophilia A, whose initial presentation was that of spontaneous submental and submandibular haematoma which rapidly progressed to involve multiple sites in the airway, ultimately necessitating an emergent tracheotomy...

The development of inhibitors to factor VIII (FVIII) or factor IX (FIX) remains a major treatment complication encountered in the treatment of haemophilia. Not all patients with even the same severity and genotype develop inhibitors suggesting an underlying mechanism of tolerance against FVIII- or FIX-related immunity. One mechanism may be central tolerance observed in patients in whom the FVIII mutation enables some production of the protein. The other is a peripheral tolerance mechanism which may be evident in patients with null mutation...
