OBJECTIVE Two different prothrombin variants, p.Arg596Leu and p.Arg596Gln, conferring antithrombin resistance to patients with venous thromboembolism have been recently reported. Here, we describe a novel substitution affecting Arg596 of prothrombin molecule (Arginine596 to Tryptophan or p.Arg596Trp or Arg221aTrp in the chymotrypsinogen numbering system or(More)
BACKGROUND Cancer is a prothrombotic state, with an increased prevalence of venous thromboembolism (VTE). Microparticles (MPs) are sub-micron-sized vesicles derived from activated or apoptotic cells that may play a role in VTE, although evidence of this association is still limited. OBJECTIVES To evaluate the hypothesis that elevated numbers of(More)
Venous thromboembolism (VTE) may complicate the clinical course of glioblastoma multiforme (GBM). Circulating microparticles (MPs) have been associated with cancer-related VTE. Sixty-one consecutive patients with GBM undergoing gross-total (41) or subtotal (20) surgical resection followed by radio-chemotherapy were prospectively evaluated. MPs numbers(More)
INTRODUCTION Placenta microthrombi being one of the prevalent recurrent histological findings in women with preeclampsia (PE), it is reasonable to think that the study of coagulation alterations in cord blood could be more informative than that observed in maternal blood. The aim of the present study was to measure different subtypes of microparticles (MP)(More)
INTRODUCTION Obesity has been associated with hypercoagulability and to increased risk of both arterial and venous thromboembolic events. Many different and complex changes in plasma coagulation factors have been described in patients with obesity. The aim of this case-control study is to evaluate hypercoagulability in a group of overweight and obese(More)
Severe factor V (FV) deficiency (parahaemophilia) is a rare congenital hemorrhagic disorder characterized by very low or undetectable plasma FV levels and bleeding phenotype ranging from mild to severe. We evaluated whole blood (WB) rotation thromboelastometry (ROTEM) in parahaemophilia patients and the contribution of intraplatelets FV, if any, to clot(More)
BACKGROUND Although having a non-O blood type is now regarded as a risk factor for venous thromboembolism, the strength of this association is poorly defined, as is its interaction with inherited thrombophilia. MATERIALS AND METHODS The prevalence of non-O blood group and inherited thrombophilia (deficiencies of natural anticoagulants, factor V Leiden and(More)
BACKGROUND Preeclampsia (PE) is a pregnancy complication characterized by high blood pressure and significant amounts of protein in the urine. Various coagulation abnormalities have been described in pregnant women with PE. The aim of the present case-control study was to evaluate whole blood thromboelastometry profiles, performed by ROTEM(®), in women with(More)
BACKGROUND Fully automated chemiluminescence immunoassays (CLIAs) are emerging technologies for the detection of anti-cardiolipin (aCL) and anti-β2 glycoprotein I (anti-β2GPI) antibodies for anti-phospholipid syndrome (APS) classification, which is commonly based on an enzyme-linked immunosorbent assay (ELISA) test result. CLIA and a homemade ELISA were(More)
