NCT ID: NCT06323187 Not yet recruiting - Preeclampsia Clinical Trials

Optimization of Cervical Collections in Pregnancy

OCCP
Start date: May 1, 2024
Phase:
Study type: Observational [Patient Registry]

Fetal cells are not easily obtained from pregnant patients; this curtails testing to assess the health of the fetus and the mother. Currently, the only way of diagnosing fetal genetic or chromosomal abnormalities is by invasive techniques, such as chorionic villous sampling (CVS) and amniocentesis performed at 10 to 13 weeks and after 15 weeks of gestation, respectively. Although small, there is a risk for fetal loss with these procedures. Transcervical cell sampling (TCS), similar to a Pap smear, is a platform that meets the requirements for prenatal genetic testing (genetic testing with fetal cells obtained before birth), as well as diagnosis of maternal pregnancy complication, at a very early stage of pregnancy (as early as 5 weeks) and carries low risk for the mother and the developing fetus. This study will examine cervical fluid collected using various noninvasive methods for TCS in pregnant women. The number of placental cells will be assessed against similarly obtained samples from nonpregnant women of reproductive age who lack cells derived from a placenta. Participating volunteers will provide written informed consent. Only standard medical procedures and approved devices will be used for collection of cervical fluid, minimizing risk to the participants and their fetuses. No test results or other benefits will be available to the participants.

EV Based Platform for Monitoring Therapeutics Response During Pregnancy

Start date: April 1, 2024
Phase:
Study type: Observational

The goal of this prospective observational cohort study of pregnant people at-risk of preeclampsia receiving aspirin as part of clinical care or a planned randomized controlled trial of 81mg vs. 162mg of aspirin is to generate proteomic data to show a distinct maternal and fetal Extracellular Vesicle (EV) proteome profile with aspirin treatment, and develop and validate a multi-marker panel for the monitoring of placental function in people at-risk of Preeclampsia and in response to aspirin treatment. The primary research question is: 1. Does the maternal and fetal Positive for Placental Alkaline Phosphatase (PLAP+) Extracellular Vesicle (EV) proteome profile in the 2nd and 3rd trimester of pregnancy differ between people who receive aspirin and develop (or not) preeclampsia? Participants will be asked to give blood samples up to four times during and at the end of their pregnancy.

NCT ID: NCT06239363 Recruiting - Preeclampsia Clinical Trials

Dietary Salicylates and Preeclampsia

PreSal
Start date: January 8, 2024
Phase:
Study type: Observational

Preeclampsia (PE) is an important pregnancy complication and cause of maternal and perinatal mortality and morbidity. The underlying etiology and pathophysiology of preeclampsia is incompletely understood but it involves dysfunctional cytotrophoblastic invasion, placental ischemia, and release of inflammatory and endothelial mediators. Placenta dysfunction in PE is related to angiogenic balance. Currently, therapeutic options for the prevention and treatment of PE are limited. It is known that the risk of PE is reduced by low-dose aspirin. Therefore, the influence of salicylates on the development of PE seems to need to be investigated. This project plans to examine the preventive effects of food sources of salicylic acid and compare their effects with aspirin. Therefore, the aim of the present study is thus answer the following questions. whether the maternal dietary intake of salicylates is related to placental angiogenesis; 2. whether naturally occurring salicylates have the same effects on preeclampsia development and placental angiogenesis as aspirin. To answer these questions we plan to carry out a human study with pregnant women. Due to the above the planned research aims to determine the association between maternal dietary intake of salicylates and placental angiogenesis and the risk of preeclampsia development. Although PE remains an incurable disease, the results of this project will enable the development of dietary recommendations for the prevention and treatment of preeclampsia. Moreover, the results of this study may be useful in lowering the cost of maternal and fetal complications from preeclampsia and the cost of their hospitalization.

Molecular Study of the Maternal-fetal Interface in Preeclampsia.

PREMAFE
Start date: November 20, 2023
Phase:
Study type: Observational

Preeclampsia (PE) is a major obstetric complication with short- and long-term consequences for the mother and the fetus. Early screening tools to reduce its mortality and morbidity, as well as to prevent the life-threatening consequences are needed. Thus, the detection of women at risk of suffering PE is key to apply preventive and treatment strategies. Recently, the maternal contribution to PE based on defective decidualization that prevents the establishment of a functional maternal-fetal interface has been evidenced. The main objective of this study is to identify molecular markers or aberrant maternal-fetal cell types that can be detected early in the development of the disease in chorionic villi collected during gestational weeks 9 to 14. Chorionic villi will be collected from women who have a recommendation for aneuploidy testing. The remaining fragment will be used for this study.

Nulliparous women will undergo routine clinical care at two regional hospitals with different treatment strategies, and selected to the study in three groups: low risk of preeclampsia, high risk of preeclampsia without aspirin, and high-risk of preeclampsia with aspirin treatment.

NCT ID: NCT06168461 Recruiting - Preeclampsia Clinical Trials

Daily Aspirin Treatment After Preeclampsia

Start date: November 1, 2023
Phase: Early Phase 1
Study type: Interventional

Women who develop preeclampsia during pregnancy are four times more likely to develop cardiovascular disease later in life, even if they are otherwise healthy. The reason why this occurs may be related to lasting blood vessel damage after the pregnancy but there are currently no specific treatment strategies to prevent this disease progression. This study addresses this public health issue by examining whether starting low dose aspirin therapy after pregnancy is an effective treatment for lasting blood vessel damage in order to inform better clinical management of cardiovascular disease risk in women who have had preeclampsia.
