Circulating Markers in Preterm Infants With Perinatal and Neonatal Inflammation
SepsisNecrotizing Enterocolitis2 moreCirculating markers to diagnose complications (sepsis, necrotizing enterocolitis) in preterm infants are often inaccurate, partly due to the lack of comprehensive studies with temporal evaluation from birth until a disease onset. The investigators plan to collect weekly blood samples of preterm infants from birth until 4 weeks of age to comprehensively characterize differential protein and epigenetic markers in infants with and without complications (sepsis, necrotizing enterocolitis, chorioamnionitis).
Kinetics of Inflammation Markers in Maternal Plasma: Study of the Correlation With the Diagnosis...
Patients With Spontaneous Rupture of the Fetal MembranesThe principal aim of this study is to help obstetricians to diagnose chorioamniotic infection early, in cases of premature rupture of the fetal membranes before 34 WA, by proposing earlier and more specific markers of infection than FBC and CRP. The aim is to reduce vital and functional risk of acute chorioamnionitis for the mother, the fetus or the newborn,. If the kinetics profile of one or several markers correlates strongly with the diagnosis of chorioamnionitis, it could be used in clinical practice, possibly in the context of another clinical study. The results of the study presented here are destined to be published in obstetrics journals.
Chorioamnionitis: Observation of at Risk Infants vs Standard Care
ChorioamnionitisEarly Onset Neonatal Sepsis1 moreThis study evaluates the non-inferiority of a protocol of limited evaluation (complete blood count, blood culture) and clinical observation by standardized physical examination versus the algorithm suggested in the CDC's 2010 guidelines (limited evaluation, clinical observation and antibiotic therapy) in the management of asymptomatic infants born at term to mothers with suspected chorioamnionitis. The primary outcome of the study is the difference in the prevalence of sepsis-related symptoms between the two groups.
Management of Prelabor Rupture of the Membranes at Term
Fetal InfectionChorioamnionitis2 moreProlonged rupture of membranes has been associated with increased risk of chorioamnionitis and endometritis. In this study the investigators will investigate whether an early intervention to augment labor with oxytocin is superior to expected management for spontaneous delivery (up to 24 hours).
Antibiotic Prophylaxis in Prelabor Rupture of Membranes at Term
ChorioamnionitisPuerperal Endometritis3 moreThe aims of this study are to determine whether antibiotics administered routinely in women presenting with premature rupture of membranes later than the 37+0 weeks of gestation can alter the rate of maternal and neonatal infection and to compare these rates between prompt (< 12 hour) and delayed (≥ 12 hour) induction in the group of patients not submitted to antibiotic prophylaxis.
Treatment of Chorioamnionitis After Delivery
ChorioamnionitisChorioamnionitis occurs in 1% to 5% of term pregnancies and may complicate up to 25% of cases of preterm labor. The traditional regimen used to treat intra-amniotic infection is intravenous ampicillin 2g every 6 hours and intravenous gentamicin 1.5 mg/kg every 8 hrs until delivery . In the past the recommendation has been that the antibiotics be continued postpartum until 24-48 hours afebrile. More recent studies have looked at using a one time dose of antibiotics after delivery vs treating until 24-48 hours afebrile. There have been no studies comparing treatment of chorioamnionitis with antibiotics vs no treatment with antibiotics postpartum. The aim of this study is to compare no treatment vs treatment with one dose after a vaginal delivery and one dose of antibiotics vs a full course until 24 hours afebrile after a cesarean delivery complicated by chorioamnionitis. The hypothesis is that there will be no difference in outcome between the two groups in each arm. This is a randomized study. Once the patient delivers she will be randomized to one of two groups in each arm. First arm (vaginal delivery) A: no treatment, B: treatment with a one time dose of ampicillin/gentamicin; Second arm (c/s) A: one dose of ampicillin/gentamicin/clindamycin, B: treatment with ampicillin/gentamicin and clindamycin until 24 hours afebrile. The goal of the study is to determine the optimal postpartum management of chorioamnionitis.
Assessment of Labour Progress by Intrapartum Ultrasound
Pregnancy RelatedFever2 moreAssessment of labor progress via digital exams is considered the standard of care in most delivery rooms. However, this method can be stressful, painful and imprecise and multiple exams increase the risk for chorioamnionitis. Trans-perineal ultrasound (TPUS) was found to be an objective noninvasive way to monitor labor progress. The study aim is to investigate whether, in nulliparous women, the use of TPUS during labor can reduce the number of vaginal exams and the incidence of chorioamnionitis.
Closure of Skin in ChorioAmnionitis Research Pilot Study
ChorioamnionitisPregnancy Complications3 moreThe purpose of the CSCAR pilot study is to improve the design of a full-scale trial by determining the patient recruitment rate and participation rate. The objective of the full-scale trial is to determine the optimal method of skin closure after Caesarean delivery in women with chorioamnionitis, which is an acute inflammation of the membranes and chorion of the placenta, seen typically after rupture of membranes with ascending polymicrobial bacterial infection. Women in labour with chorioamnionitis will be randomized at the time of Caesarean delivery to skin closure with either staples or sutures. The women will be followed at 6 weeks and 6 months post-partum in order to establish the occurrence of surgical site infection and wound disruption, as well as evaluation of the scar and other secondary questions. The investigators hypothesis is that closure of skin with sutures will have a rate of wound infection that is no higher than the rate of wound infection when closing skin with staples. The investigators also hypothesize that closure with sutures will have a decreased rate of wound disruption, increased patient satisfaction and decreased length of hospital stay compared to skin closure with staples.

Effect of Chorioamnionitis on Platelet Activation and Placental Vessel Among Preterm Infants by...
ChorioamnionitisPlacenta Diseases2 moreObjective:The purpose of this study was to explore the effect and mechanism of maternal chorioamnionitis on placental microvasculature and platelet activation among preterm infants by activating Wnt-Flt1 signal pathway . Methods:With clinical randomized controlled trial (RCT), the cases were matched with 1:1 according to gestational age and divided into 2 groups according to the placental pathology result: chorioamnionitis group and control group. (1) To observe the platelet parameter, birth weight, thrombrocytopenia and hemorrhage complication, such as intracranial hemorrhage, retinal hemorrhage, pulmonary hemorrhage and gastrointestinal hemorrhage. (2) To observe the miscrovascular density (MVD) in placenta, platelet activating factor (CD62p,CD63) and thrombopotetin (TPO) in preterrn infants.The placental MVD was assessed by immunohistochemical method. The platelet activating factors were detected by flow cytometry. TPO was detected by ELISA. (3) To observe Wnt5a, Flt1 and VEGF in placenta and fetal circulation.The measurement data were analyzed by pair t test and conditional logistic regression. Pearson correlation analysis was used for relationship.
