Residual vein thrombosis to establish duration of anticoagulation after a first episode of deep vein thrombosis: the Duration of Anticoagulation base…

2008

Abstract Residual vein thrombosis (RVT) indicates a prothrombotic state and is useful for evaluating the optimal duration of oral anticoagulant treatment (OAT). Patients with a first episode of deep vein thrombosis, treated with OAT for 3 months, were managed according to RVT findings. Those with RVT were randomized to either stop or continue anticoagulants for 9 additional months, whereas in those without RVT, OAT was stopped. Outcomes were recurrent venous thromboembolism and/or major bleeding. Residual thrombosis was detected in 180 (69.8%) of 258 patients; recurrent events occurred in 27.2% of those who discontinued (25/92; 15.2% person-years) and 19.3% of those who continued OAT (17/88…

Correlation between leukocytosis and thrombosis in Philadelphia-negative chronic myeloproliferative neoplasms

2009

The evidence that leukocytes may contribute to the pathogenesis of thrombosis in Chronic Myeloproliferative Neoplasms is increasing but not definitive. To further enforces whether an increased leukocyte count is associated with thrombosis and whether this effect can be modulated by cytoreductive therapy, we analyzed the clinical course of 187 patients with Polycythemia Vera (PV) and Essential Thrombocythemia (ET) followed at two Italian Institutions over a period of 7 years. The association was measured at diagnosis or before thrombotic events: a multivariable analysis was carried out using data at baseline and time-dependent covariates. We found that white blood cells (WBC) count above 9.5…

The risk of recurrent cardiovascular events in patients with increased plasma homocysteine levels is reduced by short but not long-term therapy with …

Hyperhomocysteinemia is considered an independent risk factor for atherosclerosis, atherothrombosis and Venous ThromboEmbolism (VTE) [1], [2] and [3]. Normal total plasma homocysteine concentrations range from 5 to 15 μmol/L in the fasting state. Hyperhomocysteinemia is classified as moderate (homocysteine concentration, 15 to 30 μmol/L), intermediate (> 30 to 100 μmol/L), and severe (> 100 μmol/L) on the basis of concentrations measured during fasting. Although severe hyperhomocysteinemia is rare, mild hyperhomocysteinemia occurs in approximately 5% to 7% of the general population. In this case, patients are typically asymptomatic until the third or fourth decade of life when premature Cor…

Absence of residual vein thrombosis after an episode of idiopatic deep vein thrombosis: short-term anticoagulation is safe. The extended DACUS Study

2009

Abstract Background. The optimal duration of Oral Anticoagulant Therapy (OAT) for Deep Vein Thrombosis (DVT) can be tailored by Residual Vein Thrombosis (RVT) (Siragusa S et al. Blood2003;102(11):OC183), a marker able to assess the individual risk for recurrent thrombosis. However, in patients with idiopathic DVT the safety of early interruption of OAT, because of absence of RVT, is still debated. Objective of the study. In the present study, we evaluated the safety of withholding OAT, in patients with idiopathic DVT and without RVT, three months after the index thrombotic episode. Study design. Prospective controlled study with two groups: patients without RVT stopped OAT after 3 months wh…
