BACKGROUND The optimal duration of oral anticoagulation in patients with idiopathic venous thromboembolism is uncertain. Testing of D-dimer levels may play a role in the assessment of the need for prolonged anticoagulation. METHODS We performed D-dimer testing 1 month after the discontinuation of anticoagulation in patients with a first unprovoked(More)
BACKGROUND The assessment of the risk of recurrent venous thromboembolism (VTE) is important to determine the optimal duration of secondary prophylaxis. The risk can be estimated by measuring individual parameters reflecting hypercoagulability. Because of the large numbers of such putative parameters, the assessment in individual patients is complex.(More)
In some patients with previous venous thromboembolism (VTE) D-dimer levels (D-Dimer) tend to increase after oral anticoagulant therapy (OAT) is stopped. The aim of our study was to evaluate the predictive value of D-Dimer for the risk of VTE recurrence after OAT withdrawal. After a first episode of deep vein thrombosis (DVT) of the lower limbs and/or(More)
BACKGROUND We have shown that normal D-dimer levels obtained after the discontinuation of oral anticoagulant treatment (OAT) has a high negative predictive value for recurrent venous thromboembolism (VTE). The aim of the present study was to assess the predictive value of D-dimer for recurrent VTE in subjects with a previous unprovoked event who are either(More)
PURPOSE To obtain reliable estimates of the relative efficacy and safety of low-molecular-weight heparins (LMWHs) and unfractionated heparin (UFH) in the treatment of patients with venous thromboembolism. METHODS A literature search of randomized trials evaluating LMWH and UFH for the period from 1980 to 1994 was conducted to obtain data for a(More)
OBJECTIVE To determine the effect of sex on the risk of recurrent venous thromboembolism in all patients and in patients with venous thromboembolism that was unprovoked or provoked (by non-hormonal factors). Data source Comprehensive search of electronic databases (Medline, Embase, CINAHL, Cochrane Central Register of Controlled Trials) until July 2010,(More)
OBJECTIVE This study aims to assess the predictive value of residual venous obstruction (RVO) for recurrent venous thrombo-embolism (VTE) in a study using D-dimer to predict outcome. DESIGN This is a multicentre randomised open-label study. METHODS Patients with a first episode of idiopathic VTE were enrolled on the day of anticoagulation(More)
This study prospectively evaluated the relationship between activated partial thromboplastin time (aPTT) and risk of venous thromboembolism (VTE) recurrence after oral anticoagulant (OA) withdrawal in patients with a previous unprovoked VTE event. Six hundred twenty-eight patients (331 males; median age: 67 years) were followed after OA interruption (mean(More)
BACKGROUND Optimal doses and duration of low-molecular-weight heparin (LMWH) for the treatment of superficial vein thrombosis (SVT) are still uncertain. OBJECTIVES To compare the efficacy and safety of different doses and durations of LMWH parnaparin for symptomatic lower limb SVT. PATIENTS AND METHODS Outpatients with at least a 4-cm-long SVT of long(More)
Warfarin dosing is affected by clinical and genetic variants, but the contribution of the genotype associated with warfarin resistance in pharmacogenetic algorithms has not been well assessed yet. We developed a new dosing algorithm including polymorphisms associated both with warfarin sensitivity and resistance in the Italian population, and its(More)
