A deficiency of blood coagulation factor V (known as proaccelerin or accelerator globulin or labile factor) leading to a rare hemorrhagic tendency known as Owren"s disease or parahemophilia; It varies greatly in severity; Factor V deficiency is an autosomal recessive trait;

(Dorland, 27th ed)

Parahemophilia; Owren's disease: Factor V deficiency is an inherited abnormal blood coagulation disorder caused by a deficiency of the plasma protein Factor V;When certain coagulation factors are deficient or missing, the chain reaction does not take place normally; Factor V is rare, and can be caused by inheriting a defective Factor V gene or by acquiring an antibody that interferes with normal Factor V function; An inhibitor of Factor V can be acquired after giving birth, after surgery, with automimmune diseases and certain cancers, in patients being treated wtih a certain type of fibrin glue, and from unknown sources; The disease is similar to hemophilia, except bleeding into joints is less common; In the inherited form of Factor V deficiency, a family history of a bleeding disorder is a risk factor;Excessive bleeding with menstrual periods and after delivery occurs frequently; A family history of a bleeding disorder is a risk factor; Men and women are affected equally; Symptoms: Bleeding into the skin; Excessive bruising; Nose bleeds; Bleeding of the gums; Excessive menstrual bleeding; Prolonged or excessive loss of blood with surgery or trauma; Umbilical stump bleeding;Signs and tests ;Factor V assay showing decreased activity; Slightly prolonged bleeding time (in some people); Prolonged partial thromboplastin time; Prolonged prothrombin time; Normal thrombin time

Treatment; Fresh plasma or fresh frozen plasma infusions will correct the deficiency temporarily
