Acquired Factor Viii Inhibitor

A 77-year-old man with a mechanical mitral valve on warfarin presented with an acute drop in haemoglobin and large spontaneous haematoma. He was found to have a new coagulopathy with initial labs notable for a prolonged activated partial thromboplastin time (APTT). Further workup revealed factor VIII levels less than 1%, abnormal mixing studies and elevated Bethesda titres, which was consistent with an acquired factor VIII inhibitor. Given his bone marrow biopsy result, which was positive for plasma cell myeloma, this coagulopathy was thought to be an acquired haemophilia A secondary to multiple myeloma. Anticoagulation was a challenge in this patient given his mechanical mitral valve and acquired haemophilia A. Although the patient was at risk of thrombosis due to a mechanical mitral valve, he had a bleeding diathesis and anaemia not responsive to transfusion. The decision was made to hold anticoagulation and the patient was started on myeloma treatment which included CyBorD, rituximab and daratumumab. After initiation of treatment APTT and factor VIII normalised. He eventually restarted anticoagulation under direction of his primary care doctor.

Acquired haemophilia A (AHA) is a rare and serious disorder mainly affecting elderly patients. It is caused by the production of autoantibodies directed against coagulation factors; patients present with spontaneous bleeding, potentially fatal, in the absence of familial or personal history. Autoimmune disorders, infections, solid and hematologic tumors, and drugs are predisposing factors, but up to 50 percent of cases remain unexplained. The diagnosis of AHA is confirmed by specific laboratory tests; and the therapy is a clinical challenge, due to the fact that older patients are often affected by comorbidities. By passing agents may be used when persistent bleeding or haemodynamic instability is observed; corticosteroids, alone or with immunosuppressive therapy, are necessary to inhibit the production of the autoantibodies. We describe a case in which steroids in monotherapy successfully, safely, and persistently inhibited the production of anti-Factor VIII antibodies, in an old patient admitted after rheumatologic consult.

SummaryFactor VIII complex and its interaction with antibodies to factor VIII have been studied in 17 non-haemophilic patients with factor VIII inhibitor. Low VIII:C and high VIIIR.Ag levels were found in all patients. VIII:WF levels were 50% of those of VTIIRrAg, possibly related to an increase of poorly aggregated and electrophoretically fast moving VIIIR:Ag oligomers.Antibody function has been characterized by kinetics of VIII :C inactivation, saturability by normal plasma and the slope of the affinity curve. Two major patterns were observed:1) Antibodies from 6 patients behaved similarly to those from haemophiliacs by showing second order inhibition kinetics, easy saturability and steep affinity slope (> 1).2) Antibodies from other patients, usually with lower titres, inactivated VIII :C according to complex order kinetics, were not saturable, and had a less steep affinity slope (< 0.7). In native plasma, or after mixing with factor VIII concentrate, antibodies of the second group did not form immune complexes with the whole factor VIII molecular complex. However, dissociation procedures did release some antibodies from apparently low molecular weight complexes formed in vivo or in vitro. For appropriate management of non-haemophilic patients with factor VIII inhibitor, it is important to determine the functional properties of their antibodies to factor VIII.

SummaryIn May 1990, 218 patients with haemophilia A regularly attending the Leuven Haemophilia Center were randomly assigned to a group receiving either of two newly introduced factor VIII concentrates: factor VIII-P, an intermediate purity pasteurized concentrate, or factor VIII-SD, a high purity concentrate treated with solvent-detergent for viral inactivation.Patients were followed from May 1990 until October 1991. Between August 1991 and October 1991 a clinically important factor VIII inhibitor was detected in five out of the 109 patients receiving factor VIII-P while none of the 109 patients receiving factor VIII-SD developed such antibodies. All patients acquiring an inhibitor had previously been clinically tolerant to transfused factor VIII with 200 to more than 1,000 days of exposure to factor VIII prior to May 1990. Patients with inhibitors were transfused daily with 30 U factor VIII-SD per kg body weight, which was associated with a gradual decline of the inhibitor level. In all patients the antibodies were relatively slow-acting and predominantly directed towards the light chain of factor VIII.This study demonstrates a higher than expected incidence of factor VIII inhibitors associated with the use of a specific factor VIII concentrate in multitransfused haemophilia A patients. It indicates the usefulness of evaluating newly introduced concentrates in prospective, randomized trials.

BACKGROUND Haemophilia’s are X-linked hereditary blood clotting disorders due to deficiency of factor VIII (haemophilia A) or factor IX (haemophilia B) & also has identical clinical manifestations, screening tests abnormalities and sex-linked genetic transmission. Haemophilia’s result from defects in the factor VIII / IX gene that lead to decreased amount of factor VIII / IX protein, the presence of a functionally abnormal protein, or combination of both. Haemophilia A is a classic example of an X-linked recessive trait. The severity of their bleeding depends on their factor VIII activity level; and, rarely, a woman can have very low factor VIII activity, and present with symptoms of moderate or even severe haemophilia. We wanted to study the clinical profile of patients of haemophilia admitted in a tertiary care hospital. METHODS This is a cross-sectional study enrolling 60 known cases of haemophilia A & B admitted in wards & ICU / attending OPD of a tertiary care hospital. History was obtained in detail & thorough clinical examination was carried out. Precipitating factors for bleeding (spontaneous / minor trauma / major trauma / surgical operation / dental procedure / others), family h / o bleeding were studied in detail. RESULTS Of the total 60 cases of haemophilia, majority (49) of cases were of haemophilia A and 11 cases were of haemophilia B. In the study, majority (28.33 %) of cases belonged to 12 - 20 years age group and the most common presentation was haemarthrosis (61.67 %). 6 patients had factor VIII inhibitor antibodies and all of them were of haemophilia A. CONCLUSIONS Haemarthrosis is the most common clinical presentation of haemophilia and most common cause for haemarthrosis is spontaneous bleeding. Most common joint involved in bleeding was knee joint (target joint). Presence of factor VIII inhibitor antibodies specially in haemophilia A patients is not uncommon.
