Up to 8% of patients receiving heparin are at risk to develop HIT antibodies, but only 1–5% on heparin will progress to develop HIT with thrombocytopenia and subsequently one-third of them may develop arterial or venous thrombosis. [1] After vascular surgery, 34% of patients receiving heparin developed HIT antibodies without clinical symptoms ...
Factor V Leiden is an autosomal dominant genetic condition that exhibits incomplete penetrance, i.e. not every person who has the mutation develops the disease. The condition results in a factor V variant that cannot be as easily degraded by activated protein C. The gene that codes the protein is referred to as F5.
There have also been cases in patients with other deficiency, including protein S deficiency, [6] [7] activated protein C resistance (Factor V Leiden) [8] and antithrombin III deficiency. [ 9 ] Although the above hypothesis is the most commonly accepted, others believe that it is a hypersensitivity reaction or a direct toxic effect.
Coagulation factor V (Factor V), also less commonly known as proaccelerin or labile factor, is a protein involved in coagulation, encoded, in humans, by F5 gene. [5] In contrast to most other coagulation factors, it is not enzymatically active but functions as a cofactor . [ 5 ]
Discontinuation of heparin is critical in a case of heparin-induced thrombocytopenia (HIT). Beyond that, however, clinicians generally treat to avoid thrombosis. [32] Treatment may include a direct thrombin inhibitor, such as lepirudin or argatroban. Other "blood thinners" sometimes used in this setting include bivalirudin and fondaparinux.
The exact prevalence of protein S deficiency in the population is unknown; it is found 1.3–5% of people with thrombosis. [14] The minor ("type 2") thrombophilias are much more common. Factor V Leiden is present in 5% of the population of Northern European descent, but much rarer in those of Asian or African extraction.
Human Chr 3. In terms of the cause of protein S deficiency it can be in inherited via autosomal dominance.A mutation in the PROS1 gene triggers the condition. The cytogenetic location of the gene in question is chromosome 3, specifically 3q11.1 [6] [7] Protein S deficiency can also be acquired due to vitamin K deficiency, treatment with warfarin, liver disease, kidney disease, chemotherapy ...
Many cases of congenital dysfibrinogenemia are asymptomatic. Since manifestations of the disorder generally occur in early adulthood or middle-age, younger individuals with a gene mutation causing it may not have had time to develop symptoms while previously asymptomatic individuals of advanced age with such a mutation are unlikely to develop symptoms.
