FACTOR V AND VIII INHIBITOR IN PATIENTS WITH COMBINED FACTOR V AND VIII DEFICIENCY

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...

Combined Factor V and VIII Deficiency

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...

Frequency of Factor V Leiden and Prothrombin Polymorphism in South of Iran

Normal hemostasis requires balanced regulation of prothrombotic and antithrombotic factors. Inherited alteration of factor V and prothrombin gene, the G20210A mutation, increases the resistance of factor V to degradation and booster production of prothrombin respectively. These alterations can increase hypercoagulability leading to thrombotic consequences. We aimed to assess the frequencies of ...

A Pregnant Woman with Factor V Deficiency

The factor V (FV) gene ASP79HIS polymorphism modulates FV plasma levels and affects the activated protein C resistance phenotype in presence of the FV Leiden mutation.

BACKGROUND AND OBJECTIVES In carriers of the factor V (FV) Leiden mutation, different trans-acting gene variants (HR2 haplotype and FV Cambridge mutation) affect activated protein C (APC) sensitivity. Among a series of FV gene variants characterized, the Asp79His polymorphism appeared to be a good candidate for the modulation of FV activity. DESIGN AND METHODS In a group of 150 apparently hea...
