Filter by:Preeclampsia complicates about 2-7% of pregnancies and is a major contributor to maternal and neonatal morbidity and mortality worldwide. Imbalance between circulating angiogenic and antiangiogenic factors has emerged as a potential key pathway in the pathophysiology of preeclampsia. Patients with preeclampsia have a higher circulating concentration of antiangiogenic factors (ie, soluble vascular endothelial growth factor receptor-1 [sVEGFR- 1], also called soluble fms-like tyrosine kinase 1 [sFlt1]) and soluble endoglin (sEng)] and a lower maternal circulating concentration of free angiogenic factors (ie, vascular endothelial growth factor [VEGF] and placental growth factor [PlGF]) than patients with a normal pregnancy. Bronchopulmonary dysplasia is the main respiratory sequelae of preterm birth. Its rate increased in preterm infants born from mother with preeclampsia. Recent studies showed that bronchopulmonary dysplasia is consistently accompanied by a reduction in the number of small arteries and on abnormal distribution of vessels within the distal lungs. This is associated with reduced lung VEGF expression. The main objective of this population-based study, ie in intra uterine growth restricted preterm babies born before 30 weeks of gestational age, was to examine whether levels of sFlt1 at birth in maternal and umbilical cord blood and in the amniotic fluid is associated with an increased risk of BPD.
The investigators plan to identify 80 pregnant women at low risk for obstetrical complications and replace 4-5 routine third trimester visits with a structured program of home weight, blood pressure and urine protein monitoring along with regular structured phone interviews and a 28 week ultrasound. The investigators hypothesis is that this protocol is both safe and acceptable.
Late intrauterine growth restriction is infrequently diagnosed with an overall sensitivity of 40 % in low-risk pregnancies. In addition, late intrauterine growth restriction may be associated with intrauterine death and poor neonatal outcomes i.e. birth asphyxia and hospitalization in intensive care unit. The investigators hypothesis that a later third trimester routine ultrasound may be more accurate to diagnose late intrauterine growth restriction.
The Antiphospholipid Syndrome is an immune disease where the presence of antibodies directed against cell membrane phospholipids (antiphospholipid antibodies) can cause an hypercoagulable state that causes thrombosis and obstetric complications (miscarriages, stillbirths). Since 1999 the Sapporo Criteria for Antiphospholipid Syndrome diagnosis includes the development of fetal growth restriction (diagnosed postpartum), but this was done without solid evidence of a relation between the two or using the most common form of fetal growth restriction diagnosis (ultrasound). Our study will try to add information to this particular point.
The purpose of this study is to investigate whether treatment with progesterone for patients with first trimester vaginal bleeding will alter the rates of obstetrical complications and adverse pregnancy outcomes.
Prediction of Low Birth Weight Infants using Ultrasound Measurement of Placental Diameter and Thickness
The purpose of this study is to assess the potential prognostic value of seric concentrations of EG-VEGF for Pre-eclampsia and/or intrauterine growth restriction and will allow checking whether plasma levels of EG-VEGF at 14-18 weeks of gestation could be proposed as prognostic marker for preeclampsia.
Study of safety of Saizen® in children born with serious intra-uterine growth retardation (IUGR) treated to final height. An open, phase III study involving 17 centers in France. The study enrolled children who have completed 3 or 2 years of treatment and at least one year of post treatment observation in the Sponsor Studies GF 4001 (Safety and Efficacy of Saizen in the Treatment of Young Children Born with Severe IUGR) or GF 6283 (Effect of Intermittent versus Continuous Saizen Therapy in Young Children Born with Severe IUGR), respectively. Detailed description: Serious IUGR is a syndrome characterized by low birth length and weight for gestational age (less than 10 percentile). The secretion of growth hormone in response to provocative stimuli (e.g. arginine, insulin) is normal in these children. Apart from low birth weight, children born with IUGR may have minor or major malformations. A catch-up period with a supraphysiological growth velocity generally occurs during the first 6 to 24 months of life in 80 to 90 percent (%) of these children. This generally allows them to reach normal height. That means that conversely, approximately 10 to 20% of children do maintain a statural handicap. Puberty occurs at a normal age and the retardation in bone maturation present during the first years of life disappears very quickly. This leads to short adult stature in subjects who have not shown spontaneous catch-up during the first years of life. A safe and effective means of promoting growth without accelerating the timing or tempo of puberty would therefore be desirable.
The purpose of the study is to investigate if treatment with an anticoagulant drug increases birth weight in pregnancies complicated by fetal growth restriction.
Normal growth and development of twins are important for the long-term health of the children. The purpose of this study was to empirically define the trajectory of fetal growth in dichorionic twins using longitudinal two-dimensional ultrasonography and to compare the fetal growth trajectories for dichorionic twins with those based on a growth standard developed by our group for singletons. This knowledge may lead to interventions that could minimize or prevent pregnancy and newborn health problems in the future.
