Active clinical trials for "Pre-Eclampsia"

The Biobank includes data and biological specimens of women from three original studies: 1) First-trimester Prediction of Preeclampsia (PREDICTION Study, NCT02189148), 2) Pre-Eclampsia And growth Retardation, an evaluative Longitudinal study (PEARL Study, NCT02379832), 3) Effect of Low Dose Aspirin on Birthweight in Twins: The GAP Trial (NCT02280031) and 4)PREDICTION2: Prediction of Preeclampsia and other Pregnancy Complications Following Combined Iterative Screening.

Procalcitonin is a protein consisting of 116 amino-acids which can rapidly rise under inflammatory conditions and sepsis. More than 20 years ago it has been shown that dipeptidylpeptidase-4 (DPP-4) cleaves procalcitonin from the n-terminus, resulting in a truncated procalcitonin-variant which consists of 114 aminoacids. Within our workgroup we found that the truncated procalcitonin-variant had deleterious effects on vascular integrity during sepsis in mice. However, it is unknown if this applies also in humans. By using an ELISA-assay we want to examine the ratio between native and truncated human procalcitonin during diseases accompanied with hyperprocalcitoninemia and correlate the results with clinical data.

Randomized trial comparing risk of hospital readmission and hypertensive complications between patients managed on Labetalol compared to Nifedipine.

Preterm preeclampsia is a severe condition for both the mother and the fetus. Currently, the only treatment available to stop disease progression is termination/delivery of the fetus and placenta. Therefore, preterm preeclampsia carries the highest rates of neonatal morbidity and mortality due to iatrogenic preterm birth. There is evidence suggesting metformin, a drug commonly used to treat diabetes in and outside pregnancy, may be able to counter the pathophysiology of preeclampsia, raising the possibility that it could be used to treat the condition. This multi centre double blind randomised controlled trial aims to investigate if metformin can prolong gestation, lower neonatal length of stay and increase birthweight in a Swedish setting.

In view of the known link between pre-eclampsia, overweight/obesity and chronic kidney disease, the aim is to offer for obese and overweight patients to reduce their BMI without reducing lean body mass. The POPADIPE project will make it possible to limit overweight or obesity by means of nutritional management chosen by the patient (hypocaloric or a dissociated diet). The latter has been the subject of little scientific investigation, particularly in relation to the management of post-pre-eclampsia.

The primary purpose of this pilot study is to determine the pharmacokinetic (PK) parameters and collect preliminary safety data for pravastatin when used as a prophylactic daily treatment in pregnant women at high risk of preeclampsia.

Findings regarding the presence of xanthine oxidase and uric acid in different blood locations is important in preeclamptic women. We aim to detecting Xanthine oxidase and uric acid levels in both umbilical cord artery and vein as well as maternal blood (3 "locations") in pregnant women with and without diagnosis of preeclampsia. The study population will be divided into groups matching the three "locations" in order to describe and compare outcome levels.

This is a study of the feasibility of a translational research clinic for pregnancies conceived by in vitro fertilisation (IVF). A group of at least 120 pregnancies (of which, at least 80 IVF-conceived) will be followed from early pregnancy to delivery, in order to gain early insights into the growth of the baby before birth, the physical and emotional adaptation of the mother to the pregnancy and how the placenta works. The investigators will collect preliminary data on how these factors may differ between pregnancies conceived with and without IVF, and between different IVF treatment modalities such as fresh or "frozen" embryo transfer IVF. The study aims to understand the practicalities of such a clinic, to identify barriers to participation in the clinic, to assess the uptake of different research measurements and to identify key measurements/time points with the greatest potential to identify and understand the origin of fetal growth and maternal adaptation differences after IVF conception in a full scale study.

Our objectives in this qualitative exploratory study: To explore the perspectives and preferences of women with preeclampsia and/or GDM history related to a potential health promotion program To identify perception of support services post-birth related to health behaviors To identify perception of personal and children's risk of future health issues related to GDM and preeclampsia history To explore effective intervention strategies and approaches for potential intervention To identify barriers and facilitators to adoption and adherence to healthy lifestyles changes in women with preeclampsia and/or GDM history Based on our results, literature review and counselling by a panel of health promotion experts, the investigators will design protocol and guidelines for a future interventional health promotion programs Methods: Study Design The proposed study consists of a qualitative exploratory study in different populations of women who underwent gestational diabetes or pre-eclampsia. Health care providers who provide care to women with gestational diabetes and pre-eclampsia will be interviewed to explore effective intervention strategies.

Although extensively studied, the cause of preeclampsia remains uncertain other than it is thought that the placenta plays a critical role in the development of preeclampsia. Recent data revealed that exosomes released from the placenta could cause preeclampsia by transporting specific cargo responsible for the pathophysiological changes associated with the systemic disease. By isolating these exosomes from maternal blood and placental tissue in patients diagnosed with preeclampsia and studying their biochemical, cellular and molecular mechanism in an animal model, the investigators hope to elucidate the critical role that exosomal cargo plays in the development of preeclampsia and cardiovascular remodeling. This will be accomplished by obtaining patient samples from volunteers delivering at the Women and Infants Center and taking the samples to the lab for quantification, characterization, and identification of key functional roles through in/ex vivo, in vitro, and profiling studies. The investigators believe this work will be valuable as hope exists to define the functional role exosomes play in the development of preeclampsia that leads to cardiovascular remodeling. Data from this study will shed more light on the functional role of exosomal cargo in normal and pathological pregnancies and point towards novel therapeutic intervention strategies for preeclampsia associated with cardiovascular disease.
