Active clinical trials for "Eclampsia"

Scoring systems for use in intensive care unit (ICU) patients have been introduced and developed over the last 30 years. They allow an assessment of the severity of disease and provide an estimate of in-hospital mortality

The primary objective of this study is to demonstrate that plasma concentrations of nucleosomes and free DNA differ between three groups: pregnant patients with complications typical of placental insufficiency or venous thrombosis (group P), healthy women (Group T1) and healthy pregnant women (Group T2).

To study calcium metabolism and the renin-angiotensin system in hypertensive and normal pregnancy.

Preeclampsia (PE) affects from 2 to 8% of pregnant women. Recent studies show that prevention is the best strategy to improve perinatal outcomes. Therefore, the development of new strategies for preeclampsia screening becomes essential in order to determine the individual risk for each patient, and thus, to identify those who would be candidates for receiving prophylactic treatment with low-dose aspirin from the first trimester of pregnancy. The aim of our study is to determine prospectively, during clinical practice, the predictive and preventive capacity of a model of preeclampsia sequential screening in the first trimester of pregnancy. This is a prospective, multicentre, cohort study, with the collaboration of Hospital de la Santa Creu i Sant Pau (Barcelona), Hospital Universitario de Cruces (Bilbao), Hospital Son Llàtzer (Mallorca) and Hospital Clínico Universitario Lozano Blesa (Zaragoza). Women with a singleton pregnancy attending to the 12-week ultrasound scan at one of the maternity hospitals participating in the study between March 1st 2021 and 30th October 2021 will be recruited. Patients who accept to participate in the study will be classified into three risk groups (low-risk, moderate-risk and high risk) based on medical history, Mean Arterial Pressure (MAP), Pregnancy-Associated Plasma Protein A (PAPP-A) and Uterine Artery Pulsatility Index (UTPI). Placental Growth Factor (PlGF) will only be determined in those patients classified as intermediate risk after this first step and then reclassified in high and low-risk patients depending on its values. The number of first-trimester scans performed by these hospitals is approximately 8200 patients annually. Due to PE prevalence in our environment is around 3% of the total population, a total of 246 cases of PE are to be expected. Therefore, based on similar previous experiences, we could assume that 80% of the patients will accept to participate in the study, meaning a total sample of 6560 pregnant women.

The aim of this feasibility study is to test recruitment of participants into Phase 1 of the study and then the re-recruitment and retention of participants in Phase 2 of the study. The investigators will also be assessing the acceptability of recruitment strategy and data collection to participants. The effect of pre-pregnancy factors (biophysical, genetic, socioeconomic, behavioural and psychological) on obstetric, cardiovascular, socioeconomic, behavioural and psychological outcomes will all be examined.

Neutrophil/lymphocyte ratio (NLR) is a marker of systemic inflammation and endothelial dysfunction. In recent years, it has been reported that the individual components of the differential white cell count, specifically the neutrophil and lymphocyte counts,may have clinical utility in predicting diseases. An elevated NLR has been shown to be a prognostic indicator in various malignancies. İn the literature, many studies have been shown that NLR have predictive value in determining the prognosis of various diseases (cardiac or noncardiac diseases ). However, little is known about the predictive values of NLR in pregnancy complications. This study aimed to evaluate the potential predictive value of NLR in preeclampsia- eclampsia.

To compare 25(OH)D level in patients with pre-eclampsia, eclampsia and normotensive pregnant women as well as to study the prevalence of Vitamin D deficiency among the 3 groups.

Pregnancy is considered a cardiovascular (CV) stress test, and complicated pregnancies are associated with an increased risk for cardiovascular disease (CVD) later in life. Moreover, it is known that often the pregnancy induced CV adaptation does not resolve completely after a short postpartum (PP) period and it is not clear whether these induced changes will resolve over a longer period of time (i.e. in the upcoming months/years after delivery). Understanding the cardiac adaptation during pregnancy and the reversal process in the postpartum period, as well as the factors that influence this these processes, may provide us not only insight in this mechanism, but may help us in identifying factors that may be target points for modification.

Preeclampsia (hypertension during pregnancy) is a common problem affecting 2-8% of pregnancies worldwide and is typically diagnosed by increased blood pressure and proteinuria. The rate of preeclampsia has increased since the 1980s with higher rates at extreme maternal ages as well as during the first pregnancy. Pre-eclampsia is a serious hypertensive disorder of pregnancy affecting outcomes for both mother and infants. These infants not only have increased risk of neonatal complications including preterm birth, intrauterine growth restriction, abnormal Doppler parameters, feed intolerance, intestinal problem, poor growth, and long term lung condition but also have increased risk of cerebral palsy, abnormal neurodevelopmental outcomes, cardiovascular disease, stroke, and mental disorders during childhood and adulthood.

The reason for having a higher incidence of preeclampsia in primiparas may involve angiogenesis imbalance in these patients.
