CellulaR Injury and Preterm Birth (CRIB)
2 oktober 2019 uppdaterad av: University of Pennsylvania
The goal of this study is to examine how cellular dysfunction can lead to preterm birth.
Women with singleton pregnancies with spontaneous preterm labor, preterm premature rupture of membranes, and cervical insufficiency (20 to 36-6/7 weeks gestation), and term deliveries (greater than 38 weeks) will be enrolled.
Medical/obstetric history and pregnancy outcomes will be recorded.
Maternal blood, urine and cervical cells (enrollment); cord blood and placental biopsy (delivery) will be collected.

Detaljerad beskrivning
Despite improvements in prenatal care, preterm birth (PTB) remains a leading contributor to perinatal morbidity and mortality.
Several genetic and environmental factors have been associated with spontaneous preterm birth, but the pathways by which these factors induce preterm delivery have not been defined.
The March of Dimes CPR at the University of Pennsylvania was created to help elucidate the pathogenesis of preterm birth by bringing together a diverse team of investigators with expertise in preterm birth, cellular metabolism, genetics, mitochondrial functional analyses, genome, epigenome, and transcriptome profiling, integrated bioinformatics analyses, and microbiome research.
The center will focus on addressing the interactions between bioenergetics, genetics, microbiome, abnormal cervical remodeling and placental dysfunction.
Each one of these factors will be studied independently and in relation to the other factors.
In order to study metabolic processes in relation to spontaneous PTB, a prospective case-control study will be performed.
This study will involve women with singleton pregnancies with spontaneous preterm labor (PTL), preterm premature rupture of membranes (PPROM), and cervical insufficiency, between 20-0/7 and 36-6/7 weeks gestational age (cases), and women with term deliveries (38 to 41 weeks gestation, controls).
The investigators will obtain information regarding the patients' pertinent past medical and obstetric histories, and the following specimens will be collected: maternal blood, maternal urine, and cervical epithelial cells at enrollment; and umbilical cord blood and placental biopsies at delivery.
We will follow and record each of these patients' pregnancy outcomes.

Studera befolkning
At HUP, there are approximately 4,200 deliveries a year, of which approximately 10 percent (420) deliver preterm.
Among these preterm births, two-thirds (280) are spontaneous, which is the focus of our research.
Many women who ultimately have a preterm birth, first present with preterm labor.
Women who have advanced dilatation, preterm rupture of membranes, etc are at high risk for having a preterm birth.
The investigators anticipate, based on the number of spontaneous preterm births at HUP per year, enrolling about 40-50% of those eligible and understanding that about 40% of those enrolled will have a preterm birth, we should be able to enroll about 112 women per year over 5 years.
The coordinators will enroll cases who are admitted to the hospital with PTL, PPROM, or cervical insufficiency at 20-0/7 to 36-6/7 weeks.
