Active clinical trials for "Pre-Eclampsia"

This study will compare between combination of colloids/crystalloids and crystalloids in women with preeclampsia undergoing elective cesarean delivery under spinal anesthesia

Use of Postpartum uterine curettage in reducing hospitalization time or in improving the clinical evolution of the patient with preeclampsia/eclampsia.

The exact mechanisms by which aspirin prevents the development of preeclampsia in high-risk patients are currently not fully known. Furthermore, a small proportion of high-risk patients who are on low-dose aspirin (LDA) still go on to develop preeclampsia (PE). This longitudinal observational study will assess the immune profile in participants who are taking low dose aspirin (LDA) in pregnancy. As part of routine care, patients at high risk of developing preeclampsia are treated with LDA from 16 weeks gestation. The study will be conducted at Barts Health National Health Service (NHS) Trust. The study population will comprise of 2 groups of participants: Those who respond to LDA and do not develop preeclampsia (responders) Participants who do not respond to LDA and develop preeclampsia (non responders) Participants will be consented at their booking appointment. Participants will be eligible if they have a singleton pregnancy and are aged over 18 years. They will have an additional blood sample taken at 12, 20, 28 and 36 weeks gestation. The blood samples will be tested to assess immune cell function, metabolism and genetics. This will identify cumulative changes in immunobiology at key time points in pregnancy.

This proposal has three aims to characterize the relationship between aspirin therapy, platelet function response, and prevention of hypertensive disorders of pregnancy (HDP) through a prospective, cohort study using pharmacokinetics, pharmacodynamics, pharmacogenomics and bioinformatics. The results of this proposal will provide necessary data for prospective study on individualized aspirin dose adjustment for prevention of HDP.

The investigators are conducting a single center, randomized controlled trial testing the impact of a neonatal sleep intervention, the SNOO, on reducing maternal blood pressure (BP) in the postpartum period in women with hypertensive disorders of pregnancy. The SNOO is a responsive bassinet designed to automatically calm and consolidate infants by responding to their cries. Use of the SNOO has been demonstrated to improve infant sleep by 1-2 hours nightly, thus increasing maternal sleep time. The investigators plan for 110 women with pregnancies complicated by gestational hypertension or pre-eclampsia to be randomized 1:1 to either receive and use the SNOO responsive bassinet for their infants, or to receive the usual care of safe sleep education. Women will be followed longitudinally through 6 months postpartum with serial BPs, weights, mood assessments, and subjective and objective sleep assessments. The investigators hypothesize that for women with pregnancies complicated by gestational hypertension or preeclampsia, that poor maternal sleep quality contributes to increased BP in the postpartum period. The investigators further propose that compared to usual care (safe sleep education), an intervention targeted to improve neonatal sleep (the SNOO), and thus maternal sleep, will improve postpartum BP for these women.

Pre-eclampsia and eclampsia cause 50,000 deaths annually. While MgSO4 is a widely accepted and relatively inexpensive treatment for these conditions, barriers to delivery via IV injection in low-resource settings pose a large obstacle to reductions in mortality. AutoSyP is a low-cost, low-powered automatic syringe pump that could overcome this barrier to the delivery of MgSO4. We propose to conduct a pilot clinical evaluation of its ability to deliver MgSO4 to women with pre-eclampsia or eclampsia in Malawi. AutoSyP will be the subject of a 2 phase pilot clinical community trial in Malawi. Prior to the start of the study, all nurses will receive a 4-hour training on AutoSyP use to ensure proper procedures are followed. Phase 1 will be an initial validation of the clinical performance of the device delivering only standard IV saline to 10 stable women. The study will continue to Phase 2 where, the device will deliver MgSO4 to up to 40 women presenting with symptoms of pre-eclampsia. Prior to the start of the study, all nurses will receive a 4-hour training on AutoSyP use. Eligible and willing participants will provide informed consent. Then, baseline demographic and relevant medical history information will be collected. In Phase 1, subjects will receive IV saline fluids by the Nurse. In Phase 2, the Nurse will provide loading dose of MgSO4 with the AutoSyP and research staff will monitor and record device performance and treatment specifications. Subsequent maintenance doses of saline or MgSO4 will be administered and observations monitored and recorded for up to 24 hours as clinically indicated. Others may benefit from this study in the future as AutoSyP is a new delivery system is needed to break down the barriers to IV delivery of MgSO4 in low-resource settings. The results of this study will be made available to the Ministry of Health, NHSRC, COMREC, the College of Medicine Library, the Department of Paediatrics, and other partners working in neonatal and child health. Findings will be published in academic journals and conference proceedings in an effort to disseminate results to potential end-users. The research findings of this study will be critical in the evaluation of future interventions.

Pregnant women at a higher risk for pre-eclampsia (PE) should be offered preventive daily treatment with acetylsalicylic acid (ASA) started before 16 weeks of gestation. To select patients at higher risk for PE, multiparametric assessment combining maternal history, biochemical factors and biophysical factors should be used during the first trimester of pregnancy. Multiparametric risk assessments have a detection rate for early-onset PE around 80% at a false positive rate of 10%. Owing to the low prevalence of early-onset and preterm PE, more than 90% of patients considered at high risk, at the first-trimester screening, will not eventually develop PE. Thus, ASA treatment would be innecessary and could be safely discontinued in these patients. The sFlt-1 to PlGF ratio has a high negative predictive value for PE during the second and third trimester of pregnancy. Thus, it could be used to detect false-positive patients from the first-trimester screening. This is a multicentric, randomized, open, parallel, controlled, phase III trial, where 1,080 patients under treatment with ASA for being at high risk for preeclampsia from the first-trimester screening, will be candidates to participate. Patients with a sFlt-1/PlGF <38, from 24 to 27+6 weeks of gestation will be randomized at a 1:1 ratio and allocated to either continue ASA until 36 weeks or to stop ASA treatment.

In patients with suspected placental vascular disease who do not require hospitalization, the use of the sFlt-1 (Soluble FMS like tyrosin-kinase-1)/PlGF (Placental Growth Factor)/ assay can most likely help teams to define the best possible management.

To compare hypertonic saline to Lactated Ringer's solution and assess whether one speeds up the process of getting rid of extra body water faster in women with preeclampsia.

The investigators plan to enroll women with PE prospectively to evaluate incremental cardiovascular risk in those who have PE with severe features. This study includes detailed echocardiographic evaluation at several time points. With the current proposal, the investigators aim to collect blood to evaluate several biomarkers to determine if there is a correlation with short and medium-term cardiovascular risk. This opens the door to earlier detection, treatment and improved cardiovascular outcomes.
