Active clinical trials for "Pre-Eclampsia"

The purpose of this study is to understand if administration of a personalized dose of the anti-hypertensive medication, labetalol, based on patient's body-mass index, will be more effective at controlling severe hypertension during pregnancy, compared to the current standard dosing.

This is a descriptive pilot study on a ready-constituted biobank (outside the Jardé Law). It is an ancillary study to the "GrossPath" cohort (RCB ID number: 2014-A01120-47). Pregnancy generates an increased risk of thrombosis, and placenta-mediated diseases constitute a risk factor for cardiovascular pathologies responsible for significant maternal-fetal morbidity and mortality. Understanding and exploring the cellular and molecular mechanisms of dysfunctions of the vascular-placental interface could provide arguments to understand the systemic vascular risk, characterize it and finally detect it on the basis of new markers, thus opening the way for targeted preventive management to reinforce the general principles of precision medicine. Netosis is a process of activation of neutrophils, which then generate filaments containing DNA, enzymes and extracellular histones. Netosis occurs in pregnancy and is increased in vascular-placental complications. It can be studied by measuring circulating histones, particularly the citrullinated histone H3. Levels of this modified histone H3, as well as those of two other modifications, have recently been shown to increase during pregnancy. These levels have also been shown to be even greater in pregnancy complications. The aim of this study is to complete this mapping in order to obtain a precise signature for all post-translational histone modifications in normal pregnancies and pregnancies complicated by pre-eclampsia from the "GrossPath" cohort in order to propose new circulating biomarkers for placental vascular pathologies. The post-translational histone modification profiles (mapping) of pregnant women with normal pregnancies will be compared with those developing pre-eclampsia.

The target population for our study is healthy nulliparous pregnant women (first pregnancy) between the 12-16 week of pregnancy. If a subject is eligible, written consent will be obtained by person to person contact. Eligible participants will be randomized to receive either daily L-citrulline supplementation or placebo.

The objective of this study is to demonstrate that urapidil is not inferior to nicardipine for the treatment of hypertension associated with preeclampsia (PE) and that it is better tolerated. efficacy endpoint : mean arterial blood pressure corrected to 100-120 mmHg after 120 min of study drug administration. safety endpoints : clinical and biological observation for any side effect. All infants will be observed in the neonatology unit (during 48h). Pharmacokinetic study included to study : transplacental transfer, transfer in breast milk, and neonatal elimination (premature babies of mothers treated with urapidil (less than 33 WG))

The overall aims of this proposal are to improve, facilitate, optimize and equalize the existing screening system for adverse pregnancy outcomes in early pregnancy in order to limit adverse consequences for both the mother and infant, by: Creating a Swedish prediction model with population-specific risk factors, optimized for the Swedish health care system, identifying high-risk women for preterm preeclampsia and validate the model within the cohort. This would give us the possibility to start aspirin prophylaxis in time, which has been proven to reduce the risk of developing preterm preeclampsia by 50%. Validating the Fetal Medicine Foundation prediction model for detection of preterm (< 37 gestational weeks) preeclampsia in a Swedish population. Creating a prediction model identifying high-risk women for overall preeclampsia during pregnancy and birth of a small for gestational age infant in order to plan individualized surveillance for early detection, which has been proven beneficial for both the mother and infant. Creating a national pregnancy biobank with blood samples and individual clinical registry data, including pregnancy outcomes, enabling future research on prevention and early detection for various adverse pregnancy outcomes which could be such as preterm birth and intrauterine growth restriction.

This study is testing the hypothesis of whether continuous positive airway pressure (CPAP) therapy improves placental histopathology and secretory function. The main aims of the study are to identify shared mechanisms between obstructive sleep apnea and preeclampsia, both common highly morbid conditions.

Worldwide, the incidence of preeclampsia ranges from 2 to 10% of pregnancies. The World Health Organization (WHO) estimates that the incidence of preeclampsia is seven times higher in developing countries than in developed (2.8% and 0.4%). In Mexico it is estimated that preeclampsia - eclampsia is a major cause of maternal and perinatal morbidity and mortality. Because it is an idiopathic heterogeneous syndrome associated with endothelial damage, so far there is no effective treatment to decrease the morbidity and mortality of this entity, so it is necessary to strengthen prevention; the use of aspirin alone is inconclusive, in addition to the information the investigators have reduced the effect of these strategies on arterial stiffness; Moreover, it has been observed that L-arginine lowers blood pressure in this population. It is for this that is of interest to know the efficacy and safety of the combination of L-arginine low dose, which is known as an important eNOS in NO production substrate, and aspirin for its qualities of antiinflammatory and anticoagulant in the prevention of preeclampsia and also determine their effect on arterial stiffness as a noninvasive method, as is the applanation tonometry.

This is a randomized controlled trial to estimate the efficacy of low dose aspirin for preventing preeclampsia in women identified as high risk. The investigators hypothesize that the risk of preeclampsia in women identified by a first trimester multiparameter predictive model to be at high risk will be significantly reduced by initiating low dose aspirin early in pregnancy.

This study evaluates the use of AMAG-423 (Digoxin Immune Fab) in addition to expectant management in the treatment of severe preeclampsia as compared to placebo.

This will be a randomized, open-label, controlled trial of patients at high risk of developing preeclampsia examining 81 mg/day vs 162mg/day daily acetylsalicylic acid (ASA) use. Based on screening results, patients will be randomized as outlined below into one of four groups. The proposed study is a pilot to determine if the higher dose of ASA has positive impacts on measures that predict preeclampsia, compared to the lower dose. If positive findings, data from this study could be used to develop a larger trial powered to determine if the higher ASA dose can improve clinical outcomes.
