View clinical trials related to Antiphospholipid Syndrome.
Filter by:The APPLE pilot trial is a feasibility study that is a multicentre, open-label, randomized controlled trial. Pregnant women with antiphospholipid syndrome (APS) and a history of late (≥10 weeks gestation) or recurrent early (2 <10 weeks) pregnancy loss will be recruited. Eligible and consenting subjects will be assigned to one of two study arms: open-label low-molecular-weight heparin (LMWH) prophylaxis until 37 weeks gestation AND low-dose aspirin (ASA) daily until delivery, or open-label low-dose aspirin daily from randomization until delivery.
Long-term anticoagulation is widely used for secondary thromboprophylaxis in the antiphospholipid syndrome (APS) due to the high risk of recurrent events. Currently anticoagulation with vitamin K antagonists (VKAs) is the standard of care but have unpredictable pharmacodynamic properties that requiere monitoring for dose adjustment. Rivaroxaban, an orally active direct factor Xa inhibitor, has been shown to be effective and safe compared with warfarin for the treatment of venous thromboembolism and non valvular atrial fibrillation in major RCTs. No studies had been published in APS.The aim of the study is to investigate the efficacy and safety of rivaroxaban in preventing recurrent thrombosis in patients with APS compared with acenocoumarol
The purpose is to determine the hypercoagulable phenotype by thrombinography associated to an increased risk of symptomatic and objectively confirmed first venous thrombotic event. This is a case-control study in a population with patients having systemic lupus erythematosus (SLE) and/or antiphospholipid antibodies (APL). Secondary purposes are: 1. To determine the frequency of hypercoagulable phenotype in study population; 2. To analyze the sensibility: consequences of variation of hypercoagulable phenotype threshold on the importance of risk; 3. To identify (genetic and not) factors for hypercoagulable phenotype and their frequency in different groups.
The primary objective of this study is to evaluate plasmatic concentrations of free PGF and sFlt1 for blood samples taken before a first low-molecular-weight-heparin injection and also for blood samples taken on the 4th day of injections (the latter correspond to the first systematic control of platelet counts) in women who have an obstetric antiphospholipid antibody syndrome and who are initiating a new pregnancy with recommended treatment. Our goal is to test the prognostic value of these data on the occurrence of: - pregnancy loss categorized as embryonic loss (before 10 weeks gestation), fetal death (before 20 weeks gestation), stillbirths (from 20 weeks gestation to delivery), and neonatal death defined before reaching 28 days of age. - ischemic placental pathology (pre-eclampsia, retro-placental hematoma, birth of a small-for-gestational-age infant)
The primary objective of this study was to evaluate and compare the prevalence of the following psychiatric pathologies (based on the MINI5.0.0 questionnaire) among 3 groups of women (Leiden versus aP1Ab-positive versus thrombophilia-negative) with similar obstetrical histories 10 years after their initial assessment/diagnosis. - Mood disorders, including depressive episodes during the previous two weeks, recurrent depressive disorders at any point in life, dysthymia in the last two years, or any current or past manic episode; - Anxiety disorders, including current agoraphobia, current panic disorders, agoraphobia with panic disorders, current social phobia, generalized anxiety in the last 6 months, or current posttraumatic stress syndrome; - Apparent psychotic syndromes, including isolated or recurrent psychotic syndromes, past or present (clinically validated), - Current alcohol or drug problems (dependence or abuse).
The purpose of that register is to collect medical information about patients suffering of APS with or without associated SLE.
This study evaluates the benefits of hydroxychloroquine on arterial function in antiphospholipid syndrome. Briefly, the patients will be randomized in two groups, one will receive hydroxychloroquine and standard treatment, the other will receive placebo in addition of standard treatment.
The family of inflammatory/autoimmune systemic diseases (IAD) form a continuum from pure inflammatory diseases to pure autoimmune diseases, encompassing a large panel of inflammatory diseases with some autoimmune components, and vice versa. Cross phenotyping of patients with IAD should be heuristic and help revise the nosography and the understanding of these diseases.
Rare diseases frequently affect women of childbearing age. Pregnancy in these women has become less rare, but remains associated with high levels of complications. One obstacle to their optimal management during pregnancy is that there are no prospective studies of pregnancy during rare diseases and several connective tissue diseases. As a consequence, the management of these pregnancies is non-standardised in terms of treatment, monitoring (frequency of consultations, laboratory tests and ultrasound), and organisation of care. Moreover, although these women (all diseases combined) are frequently exposed to medications potentially incompatible with pregnancy, little is known about the frequency of these exposures and especially their consequences to mother and child. For these reasons, researchers and clinicians from different specialties created an interdisciplinary research group on pregnancy and rare diseases (GR2), intended to improve the management of these patients' pregnancies. Using a single computer server, the investigators plan to set up a large prospective study of pregnancies in patients with rare diseases: various forms of myositis, lupus, antiphospholipid syndrome, Sjogren syndrome, scleroderma, and inflammatory rheumatic diseases. The investigators objective is to analyse the complications of pregnancies in women with rare diseases and then to improve their management and their quality of life.
Evaluation of the effect of altering the timing of initiation of low molecular weight heparin (LMWH) administration on the pregnancy outcomes in women with antiphospholipid syndrome (APS)
