Procoagulant Vitamin K-dependent Clotting Factors
We have evaluated the contribution of depression of individual procoagulant vitamin K-dependent clotting factors to the ability of warfarin to protect rabbits against tissue factor-induced coagulation. Mean activities of individual procoagulant factors were determined, in assays with rabbit substrates, for a group of rabbits achieving a protective degree of anticoagulation with warfarin. Values...
متن کاملA case report of temporary and acquired vitamin K-dependent clotting factor deficiency without any response to administrated vitamin K
Abstract Background and Objectives Vitamin K-dependent clotting factor deficiency (VKCFD) is usually an acquired problem due to liver disease, malabsorption, and overdose of warfarin. In the present paper the significance and role of vitamin K-dependent coagulation factors in menorrhagia were evaluated. Case We present a rare case of 43 year woman with acquired vitamin K deficiency and se...
متن کاملHereditary combined deficiency of the vitamin K-dependent clotting factors
Hereditary combined vitamin K-dependent clotting factors deficiency (VKCFD) is a rare congenital bleeding disorder resulting from variably decreased levels of coagulation factors II, VII, IX and X as well as natural anticoagulants protein C, protein S and protein Z. The spectrum of bleeding symptoms ranges from mild to severe with onset in the neonatal period in severe cases. The bleeding sympt...
متن کاملFamilial deficiency of vitamin K-dependent clotting factors.
Combined deficiency of vitamin K-dependent clotting factors II, VII, IX and X (and proteins C, S, and Z) is usually an acquired clinical problem, often resulting from liver disease, malabsorption, or warfarin overdose. A rare inherited form of defective gamma-carboxylation resulting in early onset of bleeding was first described by McMillan and Roberts in 1966 and subsequently has been termed '...
متن کاملVitamin K-dependent calcium binding proteins in aortic valve calcification.
The pathogenesis of valvar calcification, which complicates the course of cardiac valve disease and also affects tissue valve prostheses, is incompletely understood. The present work explores the possible role of the vitamin K-dependent, calcium-binding amino acid, gamma-carboxyglutamic acid (Gla) in valve mineralization. Gla is normally found in the vitamin K-dependent clotting factor proteins...
