Active clinical trials for "Pre-Eclampsia"

This is an international multicentre prospective cohort study to validate the Bayes theorem based algorithms for the screening of pre-eclampsia (PE) in the first-trimester of pregnancy.

Pre-eclampsia is one of the most threatening pregnancy complications. So far neither a secure, competent therapy for PE nor effective biomarkers for a premature discovery has been achieved.The aim of our study was to identify miRNAs 136, 494 and 495 genes expression in exosomes of peripheral blood compared to umbilical cord mesenchymal stem cells conditioned media released exososomes in patients with PE, as valuable markers for PE early prediction.

Objective: To evaluate serum evaluate thiol/ disulfide levels in preeclampsia and address its relationship with its severity. Methods: This prospective study will include 50 pregnancies complicated with preeclampsia and 50 healthy pregnancies. The blood for analysis will obtain at the admission and serum thiol/ disulfide levels will measure using commercially available reagent kits. The continuous values were evaluated using Student's t-test, and categorical values were evaluated using the Chi-square test. P values < .05 were accepted as significant.

Magnesium sulphate is the first line therapy for the management of preeclampsia and eclampsia in obstetrics. Perioperative administration of magnesium sulphate has been proved to be an effective as an analgesic adjuvant. The investigators evaluated the analgesic effect of magnesium in parturients undergoing Cesarean section.

Acid/base imbalances are not well understood in pre-eclamptics, and better tools are needed to allow a thorough and meaningful evaluation. Disorders of electrolytes and albumin are common findings [13, 14], and the impact of such disorders on acid-base homeostasis has increasingly been acknowledged [4, 15]. The purpose of this prospective case-control study is to evaluate acid-base status in 100 women with mild or severe pre-eclampsia and 25 healthy controls by applying the Stewart Fencl's physicochemical acid-base model. We hypothesize that several simultaneous, and possibly offsetting, metabolic acid-base disorders will be identified and quantified, and that these may be useful to guide clinicians in their medical management and indication for delivery. Intermediate and long-term goals are to evaluate the ability of the Stewart Fencl's physicochemical acid-base model to guide fluid management and predict maternal and neonatal outcomes.

A tonic active epithelial Na+ channel (ENaC) in pre-eclampsia (PE) escaped normal hormonal control may offer an attractive explanatory model for the pathophysiology of established PE. The channel is activated by plasmin. Microalbuminuria predicts the development of pre-eclampsia in pregnant patients with pregestational diabetes type 1. The investigators hypothesize that urine-plasmin excreted in the kidneys, when proteinuria occurs, could be the cause. The investigators want to test the correlation between measurable plasmin/plasminogen in the urine early in pregnancy and the development of preeclampsia in pregnant patients with type 1 diabetes.

Hypertensive disorders of pregnancy (HDP) are with 50.000 deaths every year one of the major causes of maternal mortality worldwide, especially in low and middle income countries. This trial aims to determine whether a daily dose of combined low-dose aspirin, calcium, vitamin D3, folic acid and vitamin B12 in pregnancy reduces the incidence of pregnancy-induced hypertension in women at risk. Secondary and tertiary objectives include other maternal and neonatal outcomes.

Levels of blood pressure in adolescents with preeclampsia and eclampsia: Multicenter case-control study (Latin America). Maternities in Latin America: Two hospitals in Panama, one hospital in Mexico, one hospital in El Salvador, one hospital in Guatemala, two hospitals in Honduras, one hospital in Colombia, two hospitals in Peru and two hospitals in Bolivia. The objective is to evaluate the basal levels of blood pressure during pregnancy and determine if there is any increase that is associated with the development of preeclampsia and eclampsia without reaching the known values of 140/90 mm Hg. The sample is 1050: (350 Cases and 700 Controls).

Paradoxical fetal and maternal results of studies have led to inconsistent use of antihypertensive drugs or no treatment at all in mild to moderate gestational hypertension in the Netherlands. However, none of the studies have taken the individual maternal circulatory state or the contemplated blood pressure response into account. Hypertension may be accompanied by high (hyperdynamic vasodilated profile), normal (normodynamic profile) of low (hypodynamic vasoconstrictive profile) cardiac output, and preeclampsia is not restricted to one circulatory profile. Therefore antihypertensive drugs should be viewed upon as correctors of the hemodynamic state rather than solely reducers of blood pressure. Without taking the maternal hemodynamic profile and condition into account, generic antihypertensive treatment can be expected to result in disappointing, inadequate and paradoxical results. The investigators hypothesize that in mild to moderate hypertension, personalized hemodynamically guided antihypertensive therapy (with target systolic and diastolic blood pressure <130/80mmHg), prevents the progression to severe hypertension and/or preeclampsia compared to no treatment, without the alleged side-effects.

Hypertensive disorders are the most common medical complications in pregnancy and major causes of maternal, fetal, and neonatal morbidity and mortality. Fifty percent of hypertensive disorders of pregnancy are defined as pre eclampsia, the most important manifestation of the disease. Preeclampsia is also a significant risk factor in the development of IUGR and represents the most common cause of IUGR in the nonanomalous infant. The incidence of thrombocytopenia, neutropenia and Bronchopulmonary dysplasia is also increased in neonates with preeclampsia. The neurodevelopmental outcomes infants exposed to preeclampsia are highly variable. The study by Gray et al showed that preeclampsia is associated with a decreased risk of cerebral palsy. They also found a protective effect of maternal preeclampsia on cerebral palsy regardless of exposure to magnesium sulfate. However, contrary to this, study conducted by Shao-Wen Cheng et al has showed that infants born to pre-eclamptic mothers had lower MDI scores at 24 months of age (P= 0.04) as compared to infants without maternal pre-eclampsia. The study by Szymonowicz et al showed that neonates born to pre-eclamptic mothers had a significantly lower mean mental developmental index, and significantly more of these children had one or more impairments compared with the control group at 2 years of age. The neurodevelopmental outcomes in neonates born to preeclamptic mothers therefore remain inconclusive. Recently the role of neurobehaviour being evaluated early at 37-40 weeks of CGA is being predicted as an useful adjunct to the 12-18 month full neurodevelopmental assessment. This assumes significance in the context of initiation of early stimulation and objectivised individual developmental rehabilitation regimens for these infants.
