Intrauterine Growth Restriction Clinical Trial
Official title:
Study of the Fetal and Maternal Microbiota in Preganant Women With Fetal Defect Growth Nad Its Relationship With Inflammatory Biomarkers
It is an observational and prospective study that will include consecutively 63 controls (fetuses with estimated fetal weight above the 10th centile) and 63 fetuses with defects in fetal growth (estimated fetal weight below the 10th percentile) during the third trimester (32-26 weeks) with gestational age at birth equal or over 37 weeks. Investigators will collect: (1) Obstetric and nutritional questionnaires, (2) maternal samples between 32-36 weeks (feces), (3) intrapartum samples (maternal blood, cord blood and placenta) and (4) postpartum samples (meconic and newborn feces at 6 weeks of life)
It is an observational and prospective study to determine the influence of the gastrointestinal microbiome on the intrauterine growth restriction (IUGR). For this purpose, investigators are planning to recruit 63 women with a diagnoses of IUGR and 63 pregnant women with a normal intrauterine growth. Samples will be taken during third trimester (fecal and blood maternal sample), intrapartum (maternal blood, umbilical cord blood and placenta tissue sample) and post partum samples (meconic and newborn fecal samples at 6 weeks of life). Also, obstetric and nutritional information will be registered by means of specific questionnaires. Fecal samples will be use to study the gastrointestinal microbiome by Next Generation Sequencing techniques, whereas inflammatory biomarkers will be determine in plasma samples. ;
