Patients with coagulation factor(s) deficiency who use coagulation therapy are susceptible to forming inhibitors against coagulation factor(s). In this survey we detected factor V and VIII inhibitor in ten patients with combined deficiency of factors V and VIII from north east of Iran (Khorassan province). It was revealed in our survey that eight patients had both factor V and factor VIII i...

introduction: the prevalence of rare bleeding disorders, including combined factor v+viii deficiency are higher in iran than in developed countries. there are only a few reports which have been written concerning kidney transplantation in the patients suffering from these disorders. case report: a 22-year old girl, with a known case of combined factor v+viii deficiency, a history of bladder sto...

This review summarizes current data on the pathomechanisms and new genetic findings of combined factor V and VIII deficiency (CF5F8D). Congenital haemorrhagic disorders characterized by deficiency of two clotting factors comprise an interesting group. Among dual coagulation disorders, CF5F8D is the most common type. For the first time combined factor V and VIII deficiency (F5F8D) was reported b...

Acquired factor VIII deficiency is very rare, often fatal. It is associated with pregnancy, autoimmune diseases, malignancy, and drugs, although no underlying cause is found in 50%. A 49-year-old male was referred with right shoulder bruising. The coagulation test showed a prolonged activated partial thromboplastin time. The factor VIII level was less than 1%, and the factor VIII inhibitor anti...

Factor VIII is tightly noncovalently linked to von Willebrand factor (vWF) in plasma with a stoichiometry of 1:50, and vWF deficiency results in secondary factor VIII deficiency, with accelerated clearance of factor VIII from the circulation. We used a murine model of severe von Willebrand disease (vWF knockout mice) to study the effect of a recombinant vWF/pro-vWF preparation (rpvWF) on factor...

A new case of combined factor V-VIII deficiency is reported with in vitro studies of factors V and VIII activation by thrombin. The normal activation of factors V and VIII demonstrated in the patient's plasma and the equivalent levels of factor VIII coagulant activity and coagulant antigen support the hypothesis that a quantitative rather than qualitative defect in factors V and VIII is present...

This is a bleeding disorder caused by deficiency of clotting factor VIII. The vast majority of cases are inherited but acquired forms do exist, largely in older patients, due to autoantibodies directed against factor VIII or haematological malignancy. [2] Severity of disease depends upon levels of remaining factor activity, with normal range expressed as 50-200% (refer to local laboratory for r...
