Active clinical trials for "Pre-Eclampsia"

The purpose of this study is to see if a combined pill of Angiotensin-converting enzyme (ACE) inhibitors (a medication that helps relax your veins and arteries to lower your blood pressure) with diuretics (sometimes called water pills, help rid your body of salt and water) will control blood pressure better than a different blood pressure medication of calcium channel blocker (lower your blood pressure by preventing calcium from entering the cells of your heart and arteries). Both medications are part of our usual care for high blood pressure after delivery.

Preeclampsia (PE) is a morbid and potentially lethal complication of pregnancy and is more common in women with specific risk factors. Aspirin (ASA) is currently the only prophylactic therapy for preeclampsia in high-risk women to be recognized by the US Preventive Task Force and should be initiated early in the second trimester of pregnancy, before 16 weeks of gestation. However, currently there is no literature comparing various low-dose ASA formulations in the risk reduction of PE. In the United States, the currently available low-dose ASA is over the counter and is found in 81mg tablets. Therefore, when clinicians initiate therapy with low dose ASA, they may prescribe 1 or 2 tablets of 81mg aspirin per day depending on personal preference and cannot be assisted by evidence to guide their decision.This study aims to determine the incidence of preterm PE or PE with severe features in women taking either 81mg or 162mg in a randomized setting, from a single center. The investigators hypothesize that the information gained from this trial will permit a more accurate sample size calculation for a larger clinical trial powered to accept or reject our testing hypothesis. If our hypothesis is rejected and 162mg of daily ASA is not associated with a lower incidence of severe or preterm PE compared to 81mg, this may be due to lack of power to detect a smaller effect. The investigators would then evaluate the feasibility and results and determine whether a larger trial is reasonable.

Hypertensive disorders of pregnancy (HDP) are a leading cause of maternal and fetal morbidity and mortality worldwide. The lack of knowledge and self-care behaviors by the pregnant woman in the face of THE could be associated with their appearance. This is a randomized controlled pilot trial type study, with a control group that will receive the usual prenatal care and an intervention group that will additionally receive the nursing intervention to improve knowledge and self-care behaviors in the face of HDP. Each group will include 30 pregnant women, for a total of 60 users. The level of knowledge and self-care behaviors will be assessed before and after the intervention.

To compare the incidence of preeclampsia in obese pregnant women (BMI greater than 30) with a singleton gestation at less than 20 weeks and either a history of preeclampsia in a prior pregnancy or stage I hypertension or pre-gestational diabetes who are randomized to either 81mg/day aspirin or 162mg/day aspirin.

The study is planned to describe the prevalence and severity of cardiac, lung and optic-nerve sheath diameter (ONSD) ultrasound abnormalities in women with early onset preeclampsia with severe features. These findings will be compared with point-of-care ultrasound (POCUS) abnormalities demonstrated in our recent study on late onset preeclampsia. The primary aim of the current study will be to examine the association between pulmonary interstitial edema (PIS), as identified by lung ultrasound, and cardiac dysfunction on echocardiography, and brain natriuretic peptide (BNP), in early onset preeclampsia, after comprehensive echocardiographic assessment. The secondary aims are to assess ONSD, and to explore the association between PIS or ONSD and serum albumin. A further secondary aim will be to explore the association between POCUS abnormalities and cardiotocography abnormalities and early delivery.

Pre-eclampsia is a specific pathology of pregnancy classically associating arterial hypertension with proteinuria. Its prevalence in industrialized countries is 3 to 8% of pregnancies, which makes it a frequent pathology, and it is responsible for 30% of premature deliveries. The consequences of this pathology can be very serious for the mother:renal insufficiency, hepatic cytolysis, retro-capsular hematoma of the liver, convulsions, disseminated intravascular coagulation. Moreover, the consequences on the fetus and the pregnancy are just as serious: intrauterine growth retardation, induced prematurity, retroplacental hematoma, fetal death in utero. Pre-eclampsia therefore remains difficult to diagnose and to prognose. The diagnosis of pre-eclampsia based on blood pressure and proteinuria has a predictive value of 30% for adverse outcomes related to pre-eclampsia. In recent years, new biomarkers have been studied: PlGF, a placental growth factor, and sFlt-1, the free fraction of its membrane receptor.The pathophysiology and specificity of these biomarkers, but especially their ratio, has been widely studied and demonstrated in the diagnosis and prognosis of preeclampsia. Nevertheless, few studies have analyzed the impact of this report on the hospitalization of patients, except mainly a German study which showed a change in the decision to hospitalize in 16.9% of cases. On the other hand, no French study has been carried out on this subject. Finally, no professional recommendation fully integrates or clearly frames the use of the ratio in current practice. Its use therefore remains disparate between countries, but also within the same country, as in France, where few centers use it. The decision to hospitalize a patient with suspected preeclampsia depends on the organization of the health care system. It therefore seems interesting to analyze the precise impact on hospitalizations of the use of a diagnostic and prognostic tool such as the sFlt-1/PlGF ratio with the specificities of the French health system, which favors outpatient management.The study would evaluate the use of this promising tool in the daily management of parturients, paving the way for the development of simple recommendations applicable in the various French maternity hospitals. The hypothesis is that the use of the sFlt-1/PlGF ratio in patients with suspected pre-eclampsia would reduce the rate of hospitalization.

This is a research study to understand the changes in the heart and the cardiovascular system that may occur in women who develop high blood pressure during pregnancy.

NatPro is a two-arm, parallel-group, multi-center, randomized trial in which women undergoing frozen embryo transfer (FET) will be randomized to receive either a modified natural cycle (corpus luteum present) or a programmed cycle (corpus luteum absent).

Background: Multiple adaptations at the cardiovascular system occurs during pregnancy. In the pregnancy condition pre-eclampsia (PE), this adaptations are abnormal. Five to eight percent of all pregnant women worldwide will develop PE. PE is a pregnancy condition which is characterized with a high blood pressure (>140/90 mm Hg) and the occurrence of proteinuria (>3g/dl/24h) after 20 weeks of gestation. When untreated, this condition can have severe complications for both mother and child. It's important to monitor women with a high risk for developing PE for an early detection and treatment of this condition. For this reason, a multicenter study is set up with the following applications: NICCOMO and Maternal Venous Doppler Echography: impedance cardiograph and an echography of the heart and veins. Maltron: bio-electronic impedance analyze Remote monitoring of the high risk patients to become a more intensive follow-up Number of inclusions: 2000 pregnant women from the prenatal consultations of eight different hospitals:

Pre-eclampsia (PE) is a pregnancy-associated syndrome of variable severity, classically defined by the combination of hypertension and proteinuria in a previously non-hypertensive or proteinuric patient. These symptoms normally resolve within 2-3 months after delivery regardless of the severity of the pre-eclampsia. Regardless of its definition, preeclampsia is associated with an increased risk of obstetric events and, for the mother, an increased risk of developing chronic kidney disease (CKD), hypertension, diabetes and cardiovascular disease in the broad sense. The relationship between preeclampsia and Chronic Kidney Disease is, however, complex and not fully understood. Investigator proposes an interventional study to identify the diagnosis of Chronic Kidney Disease in patients who have developed an episode of Preeclampsia.
