Active clinical trials for "Fetal Membranes, Premature Rupture"

This study evaluates the addition of transcervical Foley catheter balloon and vaginal prostaglandin E2 induction in premature rupture of membranes. Half of participants will be used combine transcervical Foley catheter balloon and vaginal prostaglandin E2, while the other half will be used alone vaginal prostaglandin E2.

This study is designed to determine if an intracervical balloon catheter (IBC) is better than oxytocin for induction of labor in the setting of premature rupture of membranes (PROM) or breaking the bag of water prior to onset of labor. The investigators suspect that an intracervical balloon catheter will shorten the time interval from initiation of induction of labor to delivery.

CRAFT-OBS: Observational Study; To evaluate subsequent pregnancy risk of preterm birth in women with a history of previous caesarean in established labour. This prospective study using clinically acquired cervical length and quantitative fetal fibronectin data will help establish a predictive model of preterm birth <34 weeks and <37 weeks. CRAFT-RCT: Randomised controlled trial arm; To assess treatment for short cervix in women at high risk of preterm birth following a caesarean section at full dilatation CRAFT-IMG: Imaging sub-study; To aid understanding of micro and macrostructural features within the cervix which predisposes to preterm birth in women with a previous full dilatation caesarean section. This will use MRI and an advanced transvaginal ultrasound protocol and to assess if structural changes can be visualised in the cervix.

The understanding of the biological mechanisms underlying preterm birth is very limited, making prevention of preterm birth difficult. The incidence of preterm birth worldwide varies between 6%-11% in singleton pregnancies, and 64-93% of preterm deliveries occur after the spontaneous onset of labor (preterm labor). The risk factors associated with preterm birth include demographic variables such as ethnic group, past obstetric history, and complications of the current pregnancy such as infection and fetal congenital anomalies. The current study aims to investigate the basic mechanisms of preterm labor by systematically cataloging the changes in expression levels of all expressed genes whose sequences are available. The goals will be accomplished by using microarray technology followed by subsequent confirmative or complementary analyses.

Cranberries have been proved to reduce the rate of urinary tract infections in a population of women with recurrent urinary tract infections in previous studies. The purpose of the study is to examine the efficacy of cranberries in pregnant women with preterm premature rupture of membranes in a)prolonging the latent period (=the time period between the time the water broke and delivery of the fetus) and b)reduction of infectious morbidity of both the mother and infant.

Preterm birth (PTB) is the primary cause of infant death worldwide. It has been shown that a vaginal microbiota deplete in Lactobacillus species is a risk factor for preterm labour. Conversely a vaginal microbiota dominated by Lactobacillus crispatus appears to be protective for these adverse outcomes. A wide range of 'over the counter' Lactobacillus spp. containing products targeted at 'vaginal health' and formulated for vaginal administration are available, but most of them do not contain vaginal species of Lactobacillus. The primary aim of this study is to determine whether vaginal supplementation with L. crispatus CTV-05 is associated with colonisation.

Objectives: To evaluate maternal serum trace elements and heavy metals namely, aluminum (Al), chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), molybdenum (Mo), cadmium (Cd), tin (Sn), antimony (Sb), mercury (Hg), and lead (Pb) in pregnant women complicated by preterm prelabour rupture of the membranes (pP-ROM) and to compare the results with healthy pregnancies. Methods: Maternal serum levels of Al, Cr, Mn, Co, Ni, Cu, Zn, As, Mo, Cd, Sn, Sb, Hg, and Pb were measured in the study group, which included 55 pregnant women complicated with pP-ROM and 60 healthy pregnancies (control group) with respect to maternal age and gestational weeks. The maternal serum levels of trace elements and heavy metals in both groups were measured using an inductively coupled plasma-mass spectrometry (ICP-MS) and compared.

The purpose of this study is to examine whether the value of vaginal fluid cytokine levels as well as computerized fetal ECG analysis are suitable clinical parameters to detect an imminent intra-amniotic inflammation with a high risk of fetal inflammatory response syndrome (FIRS) or a neonatal early onset sepsis (EOS) and whether these parameters can be determined on a daily basis in the clinical monitoring of pregnancies complicated by PPROM.

Preterm Premature Rupture of Membranes (PPROM) is treated with an antibiotic, erythromycin or azithromycin, to prolong pregnancy. Erythromycin is taken for several days and can result in stomach upset in some patients, causing them to stop taking the medication. Therefore, azithromycin is often prescribed instead. Azithromycin is usually taken only once and stomach upset is not seen or greatly reduced. The goal of this study is to see if there is a difference between the antibiotic (azithromycin) compared to the antibiotic (erythromycin) in prolonging pregnancy in patients with Preterm Premature Rupture of Membranes (PPROM). The working hypothesis is that there is no difference in the clinical effectiveness between antibiotic regimens containing te macrolides azithromycin and erythromycin for prolonging latency in PPROM.

Our main hypothesis is to consider that the detection of biomarkers on admission combined with the length of the cervix would improve the prediction of the latency period in case of preterm premature rupture of membranes (pPROM). The primary purpose of the protocol is to assess the performance of these tests to predict a latency period <48 hours in case of pPROM.
