Active clinical trials for "Fetal Growth Retardation"

According to french recommandations for IUGR management we have to propose a CGH-array analysis if the IUGR is severe (bellow the 3rd percentile) and early (in the second trimester). However there is no data to support this point of view.

Social deprivation during pregnancy is associated to adverse perinatal outcomes. However, prenatal screening of social deprivation by reliable measurement is not performed. Prevalence of social deprivation is yet underestimated during pregnancy and vulnerable women are not being provided optimal prenatal care. Our aim is to validate EPICES score during pregnancy.

The main objectives of modern antenatal care programs are to identify high risk pregnancies then to predict any possibility of adverse pregnancy outcome as early as possible. The earliest attempts to achieve this goal were possible with the introduction of ultrasound in obstetrical practice in the 1950s. A breakthrough that enabled obstetricians to directly visualize the fetus, placenta and amniotic fluid. At first 2-dimensional (2D) imaging was employed whereby fetal biometry and placental location were detected. Later on, Doppler measurements & 3-dimensional (3D) representation became feasible further revolutionizing this area

Taybi-Linder syndrome (TALS, OMIM 210710) is a rare autosomal recessive disorder belonging to the group of microcephalic osteodysplastic primordial dwarfisms (MOPD). This syndrome is characterized by short stature, skeletal anomalies, severe microcephaly with brain malformations and facial dysmorphism, and is caused by mutations in RNU4ATAC. Although RNU4ATAC-associated TALS is a recognizable phenotype, an atypical presentation is sometimes observed, thus expanding the clinical spectrum (TALS-like phenotype). This study aims to identify new variants involved in Taybi-Linder syndrome and associated phenotypes (i.e.TALS-like). This non interventional study will be performed on patients with no proven mutation of RNU4ATAC and their blood relatives (19 samples total) by high throughput sequencing and genetic analysis of already collected deoxyribonucleic acid samples. Altogether, such a study will allow a better understanding of the molecular mechanisms responsible for the Taybi-Linder syndrome and Taybi-Linder syndrome-like phenotypes as well as the pathophysiology of these devastating forms of microcephalic dwarfism.

Objective: To investigate the role of maternal serum YKL-40 and uterine artery doppler, at gestational age 12, 20, 25 and 32 weeks, and the relation to preeclampsia and intrauterine growth restriction. The serum marker YKL-40 is related to conditions involving inflammation, infection, tissue remodeling, fibrosis and cancer. IUGR and preeclampsia are known to be related to inflammation and tissue remodeling. Methods: women attending screening for downs syndrome is scanned with uterine artery doppler and delivered blood samples at GA 12, 20, 25 and 32 respectively. When pregnancy outcome is registered by medical records blood samples are retrieved and analyzed for serum YKL-40. Serum YKL-40 are correlated to the presence of bilateral notching, preeclampsia and different degrees of intrauterine growth restriction.
