Active clinical trials for "Thrombophilia"

Consecutive patients with acute or previous venous thromboembolism are enrolled in this registry. Using a standardized questionnaire, clinical data detailing venous thromboembolism and contributing VTE risk factors are recorded. Results of technical and laboratory investigations including screening for thrombophilic disorders were additionally entered into the database.

The aim of this study is to report the clinical presentation, Microbiological, laboratory and imaging evaluation, prothrombotic factors analysis, medical and surgical management and outcomes in children with Otogenic Cerebral Sinus Vein Thrombosis (CSVT).

A number of case reports describe the association of antiphospholipid antibodies (aPL Abs) with hematological and solid organ malignancies. Especially in elderly patients, thrombotic events associated with aPL Abs can be the first manifestation of malignancy. Cancer-associated monoclonal gammopathy of the IgM type can be accompanied by positive lupus anticoagulant (LA) or an anticardiolipin (aCL) IgM. Cancer and antiphospholipid antibody syndrome (APS) can coexist in sporadic cases, while some cancer patients with or without thrombosis may show some transitory aPL Ab positivity, the most striking symptomatic clinical feature, catastrophic APS, being even described in cancer patients. Some reports suggest a significant incidence of malignancies in APS patients. Cancer was the 2nd cause of death (13.9%), after bacterial infection, during the 10-year follow-up of the 1,000 APS patients studied by the Euro-Phospholipid Project Group, but no control group was simultaneously evaluated. The risk of cancer in patients with APS is thus still uncertain. The Nîmes Obstetricians and Haematologists APS (NOH-APS) study was based on the recruitment of a cohort of women with no history of thrombosis, who had experienced pregnancy loss fulfilling the clinical criteria of obstetrical APS (oAPS), who were either positive for aPL Abs (APS group), or positive for the F5 rs6025 or F2 rs1799963 polymorphism (Thrombophilia group), or negative for thrombophilia screening (Control group). We now want to assess the comparative incidence of cancer in women for whom an oAPS diagnosis had been made. This evaluation will be carried out during the 2017 medical follow-up step, corresponding to a median follow-up of 17 years. An external, local population-derived control group, the registry of tumors in Montpellier area (Registre des Tumeurs de l'Hérault) will be used to compute standardized incidence ratios (SIRs).

This 12 week study will observe patients with and without systemic lupus erythematosus who have persistent antiphospholipid antibodies in the blood who are starting a medicine called hydroxychloroquine. It will measure if these patients have a change in a blood test called the annexin A5 resistance assay over that 12 week period.

The risk of deep venous thrombosis after radical breast surgery is known. The objective of this study is to explore hypercoagulability after radical breast cancer surgery by studying several factors for haemostasis before, during and after surgery. Ultrasound Doppler examination is realised between 24 and 72 hours post-operatively. Hypercoagulability is defined by a significant increasing level of thrombin-antithrombin, D-dimer and the endogen thrombin potential.

Acute Migraine attacks can be related to vascular or coagulation activation. Previous studies found relative high incidence of prothrombotic events in Migraine. The present study intends to assess the coagulation system and activation in patients with Migraine during steady state phase and at the beginning of attacks and after 72 hours. A control group of patients with another acute neurologic event like convulsions will be also studied. Patients will be at pediatric age and teenagers.

The aim of this study was to investigate whether NETs markers can enhance procoagulant activity and predict portal vein thrombosis in patients with live cirrhosis, so as to establish a novel predictor to guide clinical decision-making.So we recruit liver cirrhosis with portal vein thrombosis and without portal vein thrombosis treated at the Affiliated Hospital of Qingdao University and collection of blood samples.

Migraine was described as related to stroke in adults and children as well. Complete thrombophilic status was not study in large groups of pediatric patients. The purpose of our study is to assess the prethrombotic profile among children and teenagers diagnosed as suffering from migraine attacks.

Retrospective, cohort study chart review in patients with hypercoagulable states.

Patients with myeloproliferative neoplasms Philadelphia chromosome negative (MPNsPh1-) such as Essential thrombocytosis (ET), Polycythemia vera (PV) and Primary Myelofibrosis (PMF) have a higher risk of arterial or deep-vein thrombosis. This is responsible for a significant increase in mortality (up to 31% of increase in thrombosis risk in ET). Cellular inflation and blood hyperviscosity, resulting from these diseases, fail to account for these thromboses, as more than 50% of thrombotic complications happen under adapted antineoplastic drug treatment. These last years, cellular microparticles (MPs) have been shown to play a major role in thrombogenesis. MPs are generated by apoptosis or the activation of malignant cells, platelets, endothelial cells or monocytes. They are fragments of plasma membrane, smaller than 1 µm, rich in phosphatidylserine, which can express the tissue factor and serve as support for the coagulation factors. Increase in the plasma concentration of procoagulant platelet microparticles has been demonstrated in other thrombotic diseases (acute coronary syndrome, disseminated intravascular coagulation DIC, etc.). The working hypothesis is that platelet microparticles are involved in the hypercoagulability of MPNs patients.
