Active clinical trials for "Pre-Eclampsia"

This is a research study designed to help identify preeclampsia in pregnant women earlier, and possibly lead to better treatment for women preeclampsia.

In this study, the investigators assessed one of the released protein factors during the pathophysiology of preeclampsia. They evaluated vascular endothelial growth factor gene mutation which affects the angiogenesis in case of inadequate placentation and its association with Doppler changes in the pulsatility index of the umbilical artery.

This randomized, double blinded controlled trial included 1200 healthy primigravidae who attended an outpatient clinic at 16-20weeks of pregnancy. All women were randomly divided equally into two groups, group A(600 women) who received antichlamydial treatment in the form of azithromycin 1 gram single oral dose before 20 weeks of pregnancy and group B (600 women) who received no treatment(placebo). All participants were followed up for up to 6 weeks postpartum and observed for the development of preeclampsia.

The purpose of this study is to determine the features of clinical imaging, disease severity and pregnancy outcomes in posterior reversible encephalopathy syndrome with preeclampsia or eclampsia.

PRERETRO is a study for validation of the French translation of a self-questionnaire looking for a history of pre-eclampsia of more than 5 years in women who have already had a pregnancy of more than 6 months with childbirth at Brest University Hospital.

For the prediction of late-onset preeclampsia (PE) in low risk women, the investigators established a cut-off value for sFlt-1/PlGF ratio and evaluated the combination models of Elecys, second trimester uterine artery (UtA) doppler, and fetoplacental proteins for Down syndrome screening.

Justification: We have recently demonstrated that maternofetal alloimmunization was not limited to blood cells: maternal alloimmunization against a glomerular podocyte antigen expressed by the placenta can induce neonatal membranous glomerulonephritis. Early recurrent pregnancy losses, preeclampsia and intervillositis are obstetrical pathologies which share an anomaly of placentation. Pathophysiology of these diseases is not yet fully understood; nevertheless the hypothesis of an incompatibility between mother and child is often mentioned. The aim of this project is to detect and study the cases of recurrent pregnancy losses, preeclamspia and intervillositis which could be induced by tissular maternofetal alloimmunization. Materials and methods: Patients suffering from recurrent pregnancy losses of unknown origin, preeclamspia or intervillositis will be included in this project. Mothers' sera will be studied by indirect immunofluorescence and Western Blot on placental biopsies from different origins and gestational ages. This stage will enable us to detect possible maternal allo-antibodies. After detecting and revealing antibodies, nature of the target antigen will be identified by immunoprecipitation of placental extracts, using the positive sera. Immunoprecipitation will be followed by a mass spectrometry analysis of detected proteins. Expected results: This study will enable us: to detect new cases of tissular maternofetal alloimmunization to improve our knowledge of mechanisms leading to anomalies of placentation to carry out a specific, preventive therapeutic approach for cases induced by tissular alloimmunization. Key words: Recurrent pregnancy losses, Preeclampsia, Intervillositis, maternofetal alloimmunization.

The investigator measured the arterial stiffness using cardio-ankle vascular index (CAVI) test in patient with preeclampsia and normal pregnant women to evaluate the longitudinal change of CAVI and their predictors.

Background: Pre-eclampsia, defined by the association of an arterial hypertension and significant proteinuria after 20 weeks of gestation, complicates 1 to 2% of pregnancies in France. Its pathophysiology involves angiogenesis impairment, upregulated maternal systemic inflammatory response, activation of oxidative stress and endothelial dysfunction. In a recent Danish nation-wide cohort study, pre-eclampsia was associated with a 69% increased risk of later developing scleroderma. Type of study: prospective observational case-control study. Primary objective of the study: to determine if a history of pre-eclampsia before systemic sclerosis diagnosis is an independent risk factor for vascular phenotype in sclerodermic women. Secondary objective: to describe all risk factors for vascular phenotype in sclerodermic women with a previous pregnancy longer than 6 months before scleroderma diagnosis.

Twin pregnancies are associated with increased risk of perinatal adverse outcomes , including preeclampsia , fetal growth restriction , preterm premature rupture of membranes and preterm birth. Low-dose aspirin was recommend by American College of Obstetricians and Gynecologists (ACOG) during pregnancy. In this trial, the investigators suppose that aspirin used in twin-pregnancies could improve adverse pregnancy outcomes.
