Active clinical trials for "Eclampsia"

This study will recruit women with post partum pre-eclampsia and match them to controls without postpartum pre-eclampsia to identify an epigenetic signature that is specific to women with post partum pre-eclampsia to help characterize the underlying pathophysiology of post partum pre-eclampsia.

Studying the ultrastructural and immunohistochemical characteristics of Telocytes from umbilical cord vessels wall in PE patients compared to control and its relation to severity of disease whether controlled or uncontrolled.

Identifying modifiable factors that contribute to preeclampsia risk associated with assisted reproduction can improve maternal health. Recent studies have shown an increased risk for hypertensive disorders of pregnancy after in vitro fertilization, particularly for pregnancies occurring during a hormone replacement therapy such a donor egg recipient and a frozen embryo transfer. This risk may be partly attributable to the degree by which the assisted reproductive treatment affects the maternal hormonal environment, when the corpus luteum is a major source of reproductive hormones. On the other hand, cryopreserved embryos are usually thawed and replaced in in a natural or hormonally manipulated cycle; on this point, frozen embryo transfer is associated with better perinatal outcome regarding preterm birth and low birth weight yet higher risk of large for gestational age and macrosomia compared to fresh transfer. The objective of our study is to investigate whether the absence of corpus luteum adversely affects pregnancy and to analyse if there are differences in the perinatal outcomes due to differences in the endometrial preparation protocol for a frozen embryo transfer.

Pregnancy-induced hypertension is a unique abnormal blood pressure disease in women during pregnancy, including eclampsia, preeclampsia, pregnancy-induced hypertension, chronic hypertension and so on. Eclampsia can lead to convulsions, proteinuria, multiple organ failure, and eventually death. It is a very serious disease in women, and the incidence of pregnancy-induced hypertension during pregnancy is between 4% and 10%. The incidence of eclampsia ranges from 2% to 5%. Studies have shown that there are about 60,000 cases of stillbirth or stillbirth due to eclampsia every year worldwide. At present, there are many theories about the pathogenesis of eclampsia, such as oxidative stress theory, maternal and fetal interaction theory, immune imbalance theory, heredity theory and so on.

Despite advances in obstetric care, preeclampsia (PE) remains the leading cause of maternal death and disability in both developed and developing countries, contributing to over 70,000 maternal and 500,000 fetal deaths annually worldwide. PULSE was designed using a preventative medicine approach, focusing on improving early detection of PE as opposed to managing symptoms after onset. The study aims to uncover the earliest possible signs of PE using a combination of novel clinical tools and established diagnostic techniques to better identify, track, and manage high risk pregnant women. Specifically, PULSE will be examining the incorporation of a non-invasive test for the measurement of arterial stiffness, which has been shown to be predictive of hypertensive disorders. This test, in combination with a wide range of blood biomarkers, detailed ultrasound imaging, and a comprehensive battery of physical and mental health questionnaires, represents the largest, most comprehensive preventative PE study to date. The results of this work has the potential to revolutionize the way PE and other hypertensive disorders of pregnancy are managed and treated and can serve to inform the design of future preventative clinical research studies.

major objective This multicenter, prospective cohort study aims at evaluating the predictive value of microbiome ,proteomics and serum markers in preeclampsia. secondary objective to evaluate the value of microbiome,proteomics and serum markers in assessing pregnancy outcome (complications during pregnancy and delivery, delivery) and neonatal prognosis.

The investigators propose a randomized controlled unblinded trial to evaluate rates of optimal blood pressure control between Nifedipine 60mg XL once daily vs. Nifedipine 30mg XL twice daily in patients admitted for expectant management with pre-eclampsia with severe features. Patients will be approached for consent when they are placed on 30mg of Nifedipine daily by their primary provider and will be enrolled in the study when the primary provider has made the decision to increase the patient's daily dose of Nifedipine XL from 30mg to 60mg.

Preeclampsia is a multi-system progressive disorder characterized by the new onset of hypertension and proteinuria, or hypertension and significant end-organ dysfunction with or without proteinuria, in the last half of pregnancy or postpartum. The genesis of the disease is laid down in early pregnancy and is characterized anatomically by abnormal remodeling of the maternal spiral arteries at the placental site.

Preeclampsia and intrauterine growth retardation (IUGR) are serious and frequent pathologies, specific to pregnancy. They represent 70 000 new cases a year, or 9% of pregnancies and cause 50,000 premature births per year in France. The consequences in terms of morbidity and perinatal morbidity and the medical and economic costs make it an issue public health. Pre-eclampsia associates maternal hypertension with dysfunction kidney. There is no cure for pre-eclampsia or IUGR vascular during pregnancy. These pathologies invariably evolve towards a maternal and / or fetal aggravation sometimes very fast. Primary prevention and secondary education and screening for these pathologies are still insufficient. A better understanding of the pathophysiology of these placental vascular pathologies is necessary for the development of supported medical, obstetric and pediatric that will improve the state of health maternal and neonatal

Changes in the optic nerve sheath diameter detected by ultrasound are considered an important manifestation of increased intracranial pressure . The normal optic nerve sheath diameter measures up to 5.0 mm and an average optic nerve sheath diameter more than 5 mm is considered abnormal and elevated intracranial pressure should be suspected.Cerebral edema have been demonstrated in 71% to 100% of magnetic resonance imaging in preeclamptic patients and an increase in optic nerve sheath diameter has been described in preeclamptic females compared to healthy pregnant females Therefore, Increased optic nerve sheath diameter can indirectly reflect the state of intracranial edema that could be a part of generalized edema of preeclampsia and it could be a possible marker of generalized tissue edema and fluid overload in these patients.
