Infection of the genitourinary tract with Group B Streptococcus (GBS), an opportunistic gram positive pathogen, is associated with premature rupture of amniotic membrane and preterm birth. In this work, we demonstrate that GBS produces membrane vesicles (MVs) in a serotype independent manner. These MVs are loaded with virulence factors including extracellular matrix degrading proteases and pore forming toxins. Mice chorio-decidual membranes challenged with MVs ex vivo resulted in extensive collagen degradation leading to loss of stiffness and mechanical weakening...

BACKGROUND: Histologic chorio-deciduitis and chorio-deciduo-amnionitis (amnionitis) in extra-placental membranes are known to represent the early and advanced stages of ascending intra-uterine infection. However, there are no data in humans about the time required for chorio-deciduitis to develop and for chorio-deciduitis without amnionitis to progress to chorio-deciduitis with amnionitis, and the effect of prolongation of pregnancy on the development of chorio-deciduitis and amnionitis in patients with preterm labor and intact membranes (PTL) and preterm premature rupture of membranes (preterm-PROM)...

INTRODUCTION: The inflammatory milieu decreases in the placenta and amniotic fluid (AF) with gestational age (GA). However, there is no information about whether the inflammatory milieu of AF in the setting of the same placental inflammatory condition decreases with GA. We hypothesized that the inflammatory milieu of AF in acute chorioamnionitis would decrease with increasing GA. METHODS: The inflammatory milieu of AF was examined in 617 singleton preterm pregnancies (<36 weeks) delivered within 5 days of amniocentesis...

With effective antiretroviral therapy, the risk of mother to child transmission (MTCT) is now under 1%. The 2013 French guidelines emphasize early antiretroviral lifelong antiretroviral therapy. Thus, the current trend for women living with HIV is to take antiretroviral therapy before, during and after their pregnancies. A major issue today is the choice of antiretroviral drugs, to maximize the benefits and minimize the risks of fetal exposure. This requires interdisciplinary care. The use of effective therapies permits gradual but profound changes in obstetric practice...

OBJECTIVE: The proteoglycan decorin stabilizes collagen whereas biglycan and hyaluronan disrupt well-organized collagen. The aim was to determine the concentrations of these constituents in fetal membranes in relation to gestational age, preterm labour, PPROM and chorioamnionitis. STUDY DESIGN: Preterm fetal membranes (24-34 weeks gestation) were obtained from elective caesarean deliveries (N = 4), from PPROM (N = 14), and from preterm labour (N = 14). Term fetal membranes from elective caesarean deliveries (N = 9) and spontaneous vaginal deliveries (N = 11) were used for comparison...

OBJECTIVES: Fetal neutrophilia is present in two-thirds of cases with the fetal inflammatory response syndrome (FIRS). The mechanisms responsible for this finding have not been elucidated. Granulocyte colony-stimulating factor (G-CSF) is the primary physiologic regulator of neutrophil production and plays a key role in the rapid generation and release of neutrophils in stressful conditions (i.e., infection). The objective of this study was to determine: 1) whether FIRS was associated with changes in fetal plasma G-CSF concentrations; and 2) if fetal plasma G-CSF concentrations correlated with fetal neutrophil counts, chorioamnionitis, neonatal morbidity/mortality and cordocentesis-to-delivery interval...

The authors present fetal and maternal risks in chorio-amnionitis diseases. Major fetal risk is the increase of the rate of cerebral palsy which is growing to five. The protocol of 2011 is presented for the prevention and treatment of chorio-amnionitis in premature rupture of the membranes in relation with gestational age. A French statistical survey, period 2001 to 2006, indicates maternal risks of chorio-amnionitis. Medicolegal implications of the chorio-amnionitis diseases emphasize the importance of placental investigations and bacteriological tests...

Embryo-fetal infections have been reported to cause recurrent spontaneous abortions (RSAs) at a rate lower than 4%. The possible mechanisms include production of toxic metabolic byproducts, fetal or placental infection, chronic endometrial infection, and chorio-amnionitis. Viruses appear to be the most frequently involved pathogens, since some of them can produce chronic or recurrent maternal infection. In particular, cytomegalovirus during pregnancy can reach the placenta by viremia, following both primary and recurrent infection, or by ascending route from the cervix, mostly following reactivation...

The study is based on 141 pregnant Bos indicus cows, from days 20 to 70 post-insemination. First, special attention was given to the macroscopically observable phenomena of attachment of the conceptus to the uterus, i.e. the implantation, from about days 20 to 30 post-insemination up to day 70, and placentome development by growth, vascularization and increase in the number of cotyledons opposite to the endometrial caruncles. Secondly, as for the conceptuses, semiquantitative, statistical analyses were performed of the lengths of chorio-allantois, amnion and yolk sac; and the different parts of the centre and two extremes of the yolk sacs were also analysed...

REVIEW
A El Kateb, Y Ville
Fetal and perinatal loss rates are much higher in monochorionic than in dichorionic pregnancies. This is likely to be at least in part a consequence of chorio-angiopagus and severe early onset of twin-to-twin transfusion syndrome (TTTS). TTTS occurs in approximately 15% of all monochorionic pregnancies and is defined sonographically by the combination of polyhydramnios in one sac and oligohydramnios in the other. Intertwin anastomoses on the chorionic plate are responsible for the development of a net imbalance in blood flow and subsequent development of TTTS...

UNLABELLED: Some experimental work suggests that exposure to intrauterine infection is associated, not only, with lung maturation and a reduced risk of respiratory distress syndrome, but also, with delayed alveolarization and increased risk of bronchopulmonary dysplasia. AIM: To evaluate the association between histological chorioamnionitis and lung disease in extremely low birth weight preterm infants. METHODS: A retrospective chart review of 63 less than 1000 g birthweight, appropriated for gestational age neonates, delivered at three tertiary medical centers in the north of Portugal, between 2001 and 2002...
