Microparticles (MPs) are blebs released from cellular surfaces during activation/apoptosis. They are procoagulant, pro-inflammatory and could contribute to pathogenesis of deep venous thrombosis (DVT). This study compared the number, cellular origin and procoagulant activity of MPs on DVT patients in different clinical situations: at diagnosis (n = 9,(More)
The protein infusion of basic fibroblast growth factor-2 (FGF-2) and platelet derived growth factor-BB (PDGF-BB) have been shown to promote the formation of a stable and functional vascular network in small and large animal models of ischemia. Here, we sought to determine whether a similar effect could be obtained using a gene-therapy-based strategy with(More)
Increased levels of inflammatory markers and clotting factors have been related to the pathogenesis and prognosis of venous thromboembolism. In particular, the imbalance between VWF and ADAMTS13 has been described in patients with arterial thrombosis. In this study, 77 patients with previous VTE and 77 matched controls were selected for the evaluation of(More)
UNLABELLED Studies evaluating circulating endothelial cells by flow cytometry are faced by a lack of consensus about the best combination of monoclonal antibodies to be used. The rarity of these cells in peripheral blood, which represent 0.01% of mononuclear cells, drastically increases this challenge. OBJECTIVE The aim of this study is to suggest some(More)
INTRODUCTION Deep vein thrombosis (DVT) is a multi-causal disease associated with high morbidity and mortality due to complications, and 25% of patients present recurrence within 5 years. The identification of factors involved with DVT can help in the management of patients, prevention of recurrence and in the development of new therapies. The evaluation of(More)
Although deep vein thrombosis (DVT) recurrence is a common late complication of the disease, there are few predictive markers to risk-stratify patients long-term after the thrombotic event. The accuracy of residual vein thrombosis (RVT) in this context is controversial, possibly due to a lack of a standardized methodology. The objective of the study was to(More)
Postthrombotic syndrome (PTS) may affect 50% of patients with deep venous thrombosis, 5-10% of them may present severe manifestations. The causes for PTS development and severity have not been well established. This study evaluated whether PTS may be associated with the presence, and echogenicity, of the residual vein thrombosis (RVT). We included patients(More)
Scott syndrome is a rare bleeding disorder due to an impaired exposure of phosphatidilserine on the platelet membrane, compromising the platelet procoagulant activity, thrombin generation and, thus, the clot formation. We report a case of a 17-year-old female adolescent with bleeding episodes of unknown cause. She had normal coagulation, but altered(More)
