How is factor VII deficiency treated?
The main treatment for FVII deficiency is recombinant factor VIIa (rFVIIa). Prothrombin complex concentrates (PCCs) can also be used, but the amount of factor VII they contain can vary considerably. Fresh frozen plasma (FFP) is another option. In some patients, the use of FFP has led to blood clots.
How is factor deficiency treated?
How rare factor deficiencies are treated depends on the missing protein. Some can be treated with factor concentrates that replace the missing clotting factor. Others are treated with fresh frozen plasma, which is the liquid part of whole blood, or antifibrinolytics, which slow the breakdown of blood clots.
What activates factor VII?
Once bound to its cofactor, factor VII can be activated by a number of different proteases. Carboxylation by vitamin K is necessary to activate this factor. The physiologic activator of factor VII is thought to be factor Xa, although significant auto-activation by factor VIIa can occur.
What is the most common cause of factor XI deficiency?
Most cases of factor XI deficiency are caused by mutations in the F11 gene, which provides instructions for making the factor XI protein. This protein plays a role in the coagulation cascade, which is a series of chemical reactions that forms blood clots in response to injury.
What would be the result of a deficiency of intrinsic factor?
Intrinsic factor deficiency is a rare condition that is characterized by pernicious anemia and neurological abnormalities. Most affected people develop signs and symptoms of the condition before age 5 years which may include failure to thrive and symptoms related to anemia (i.e. fatigue, pale skin, etc).
Is hemophilia A serious disorder?
People with hemophilia can experience spontaneous or internal bleeding and often have painful, swollen joints due to bleeding into the joints. This rare but serious condition can have life-threatening complications. The three forms of hemophilia are hemophilia A, B, and C.
Is Factor 7 a blood product?
Factor VII is a 50-kDa vitamin K–dependent zymogen synthesized by the liver that is critical for initiation of tissue–induced coagulation (extrinsic pathway).
How to treat factor VIII deficiency?
you may be given infusions of blood clotting factors to boost your clotting ability.
What does factor VII deficiency mean?
Factor VII Deficiency. Overview. Factor VII deficiency is a blood clotting disorder that causes excessive or prolonged bleeding after an injury or surgery. With factor VII deficiency, your body either doesn’t produce enough factor VII, or something is interfering with your factor VII, often another medical condition.
How is factor V deficiency treated?
Factor v deficiency is diagnosed by finding low factor v in the blood examination. The treatment is fresh frozen plasma, or infusion of platelet concentrates since platelets have a good amount of factor v adsorbed on them, it is an effective method to raise factor v levels.
What is the history of factor VII deficiency?
Factor VII deficiency is caused by mutations of the F7 gene and is inherited as an autosomal recessive disorder. Factor VII deficiency was first described in the medical literature by Dr. Alexander, et al. in 1951 and was referred to as prothrombin conversion accelerator deficiency. The disorder has also been known as Alexander’s disease.
