Warfarin resistance is a rare condition in which people have varying degrees of tolerance to the anticoagulant drug warfarin. In incomplete warfarin resistance, people only respond to high doses of warfarin; in complete warfarin resistance, the drug has no effect. This can be because the drug is metabolized quickly or because the clotting ...
Two alternatively spliced transcripts encoding different isoforms have also been described. These isoforms result in warfarin resistance (requiring higher doses) in humans and rats, because the amount and effectiveness of the VKORC enzyme has not changed, but the ability of warfarin to exert its effect (antagonize the enzyme) has changed.
Warfarin is indicated for the prophylaxis and treatment of venous thrombosis and its extension, pulmonary embolism; [9] prophylaxis and treatment of thromboembolic complications associated with atrial fibrillation and/or cardiac valve replacement; [9] and reduction in the risk of death, recurrent myocardial infarction, and thromboembolic events such as stroke or systemic embolization after ...
Primary prophylaxis with low-molecular weight heparin, heparin, or warfarin is often considered in known familial cases. Anticoagulant prophylaxis is given to all who develop a venous clot regardless of underlying cause. [6] Studies have demonstrated an increased risk of recurrent venous thromboembolic events in patients with protein C deficiency.
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 ...
Warfarin necrosis is a rare but severe complication of treatment with warfarin or related anticoagulants. [2] The typical patient appears to be an obese, middle aged woman (median age 54 years, male to female ratio 1:3). [1] [3]: 122–3 This drug eruption usually occurs between the third and tenth days of therapy with warfarin derivatives. [1]
Insulin resistance, or low insulin sensitivity, happens when cells throughout the body don’t respond properly to the hormone insulin, especially cells in muscles, fat and the liver. Insulin is a ...
Antithrombin III deficiency (abbreviated ATIII deficiency) is a deficiency of antithrombin III.This deficiency may be inherited or acquired. [1] It is a rare hereditary disorder that generally comes to light when a patient suffers recurrent venous thrombosis and pulmonary embolism, and repetitive intrauterine fetal death (IUFD). [2]
