Multivessel Thromboembolism Associated with Dysfunction of Protein S
Protein S is a vitamin K-dependent coagulation factor that acts as an anticoagulant. Deficiency of protein S increases the risk of thromboembolic events. We report a case of isolated protein S deficiency in a 39-year-old woman suffering arterial occlusion in both lower legs. She underwent a surgical procedure using thrombectomy and balloon angioplasty of her left lower extremity. Later, she had...
متن کاملProtein C and protein S levels can be accurately determined within 24 hours of diagnosis of acute venous thromboembolism.
In the 50% of cases of acute idiopathic venous thromboembolism, laboratory testing for inherited causes is often performed. Most physicians are under the impression that assays for protein C and protein S should not be measured at the time of diagnosis because of a high false positive rate. We performed a prospective cohort study from two outpatient thromboembolism clinics on consecutive patien...
متن کاملThe risk of recurrent venous thromboembolism in patients with inherited deficiency of natural anticoagulants antithrombin, protein C and protein S.
Few data are available on the risk of recurrent venous thromboembolism (VTE) associated with the rare inherited deficiencies of natural anticoagulants. We studied 602 patients with previous VTE: the incidence of first recurrence in the absence of anticoagulation was retrospectively estimated in 64 patients with deficiency of antithrombin (AT, n=14), protein C (PC, n=28), or protein S (PS, n=22)...
متن کاملCleaved protein S (PS), total PS, free PS, and activated protein C cofactor activity as risk factors for venous thromboembolism.
BACKGROUND Although hereditary protein S (PS) deficiency is clearly associated with venous thromboembolism (VTE), the importance of low PS concentrations as a risk factor for VTE in other patients is still a matter of debate. To clarify this issue, we designed a case-control study to evaluate the role of different molecular forms of plasma PS. METHODS We quantified plasma cleaved, total, and ...
متن کاملELISA-Based Detection System for Protein S K196E Mutation, a Genetic Risk Factor for Venous Thromboembolism
Protein S (PS) acts as a cofactor for activated protein C in the plasma anticoagulant system. PS Lys196-to-Glu (K196E) mutation is a genetic risk factor for venous thromboembolism in Japanese individuals. Because of the substantial overlap in PS anticoagulant activity between KK (wild-type) and KE (heterozygous) genotypes, it is difficult to identify PS K196E carriers by measuring PS activity. ...
