Filter by:Justification: We have recently demonstrated that maternofetal alloimmunization was not limited to blood cells: maternal alloimmunization against a glomerular podocyte antigen expressed by the placenta can induce neonatal membranous glomerulonephritis. Early recurrent pregnancy losses, preeclampsia and intervillositis are obstetrical pathologies which share an anomaly of placentation. Pathophysiology of these diseases is not yet fully understood; nevertheless the hypothesis of an incompatibility between mother and child is often mentioned. The aim of this project is to detect and study the cases of recurrent pregnancy losses, preeclamspia and intervillositis which could be induced by tissular maternofetal alloimmunization. Materials and methods: Patients suffering from recurrent pregnancy losses of unknown origin, preeclamspia or intervillositis will be included in this project. Mothers' sera will be studied by indirect immunofluorescence and Western Blot on placental biopsies from different origins and gestational ages. This stage will enable us to detect possible maternal allo-antibodies. After detecting and revealing antibodies, nature of the target antigen will be identified by immunoprecipitation of placental extracts, using the positive sera. Immunoprecipitation will be followed by a mass spectrometry analysis of detected proteins. Expected results: This study will enable us: - to detect new cases of tissular maternofetal alloimmunization - to improve our knowledge of mechanisms leading to anomalies of placentation - to carry out a specific, preventive therapeutic approach for cases induced by tissular alloimmunization. Key words: Recurrent pregnancy losses, Preeclampsia, Intervillositis, maternofetal alloimmunization.
Cross sectional, hospital-based study dealing with adiponectin levels in newborns to mothers with pre-eclampsia. Venus cord blood samples were collected immediately after birth; 30 cases and 62 controls were enrolled into the study. The study was approved by the local ethics committee and all participants gave written consent.
The purpose of this study is to determine whether insulin resistance might affect the pathogenesis of hypertensive disorders in pregnancy since midtrimester. Furthermore, markers of vascular and placental injuries, of oxidative stress and inflammation will be evaluated.
The purpose of this study is a systematical registration of hemodynamic measurements (cardiac output, blood pressure and systemic vascular resistance) in women with serious preeclampsia.
The purpose of this study is to investigate antioxidants supplementation in pregnant women with low antioxidant status at 10-12 weeks gestation age in relation to adverse pregnancy outcome in randomized prospective study.
This study will examine a possible genetic basis for preeclampsia, a disorder of high blood pressure and protein in the urine during pregnancy. Preeclampsia is a major pregnancy complication affecting both mother and baby. Previous research has shown that preeclampsia tends to run in certain families. This study will determine which genes may be involved in preeclampsia. Women who have had preeclampsia (called the index woman) may be eligible for this study. They will be recruited through the Preeclampsia Foundation. In addition, the following relatives of the index woman may be enrolled: - The child from the preeclampsic pregnancy - The index woman's biological parents - The index woman's siblings who have given birth or fathered a child and their family members The study will exclude any index women or family members who have had chronic hypertension, diabetes, polycystic ovary syndrome, or whose pregnancy that involved preeclampsia was a multiple fetus pregnancy or that was conceived through use of fertility technology. All women participants fill out a questionnaire to collect demographic data (e.g., age, race, marital status, etc.) and information on their medical and reproductive history, use of tobacco and medicines, and other factors that may be associated with preeclampsia syndrome. Women who have had preeclampsia or hypertension in pregnancy are asked to sign a medical record release form for study investigators to obtain a copy of the medical record for that pregnancy. All male and female participants provide a mouthwash rinse sample for extraction of DNA for gene studies. For babies too young to rinse with mouthwash, a soft brush is used to brush the inside of the mouth to collect cheek cells. Mouthwash samples are analyzed for genes that may be associated with preeclampsia.
Magnesium sulfate is used for seizure prophylaxis in pregnancies complicated by preeclampsia. There is debate as to how long to continue this therapy after delivery of the pregnancy. Different schemes have been offered to shorten the exposure to magnesium sulfate after delivery, with little data. We seek to investigate the effect of shortened magnesium sulfate therapy on the post-partum recovery phase of mild preeclampsia. Our hypothesis was that shortened therapy (12 hours versus the traditional 24 hours post-partum) has no effect on disease course, and will result in significantly shorter exposure to magnesium sulfate.
Preterm delivery, preeclampsia and intrauterine growth restriction are leading causes of perinatal morbidity and mortality. Efforts to treat these syndromes have not been effective, most likely becuase these obstetric complications are the clinical expression of adaptive mechanisms of host defense developed in response to pathologic insults. Since the ultimate pathologic basis of disease is unclear, therapy for these syndromes has been largely directed at symptoms, which appear late in the development of the disease. The main purpose of this study is to perform an early and comprehensive exploration of maternal and fetal factors that predict the subsequent develpment of these obstetrice complications, so that early medical interventions may be tested in patients at high and low risk for adverse perinatal outcome.
This research project is studying the causes for low platelet levels in preterm infants. Platelets are a component of blood that helps with clotting. The purpose of this study is to determine whether the cause for low platelet levels is the same in infants who are born to mothers with preeclampsia and infants who are small for gestational age.
Over 10% of women have high blood pressure during their pregnancy which may affect their health or that of their baby. There are currently no methods to prevent most high blood pressure in pregnancy and some treatments are not desirable for use in pregnancy. Previous research indicates that simple relaxation methods can reduce blood pressure and anxiety levels for some people, but this has not been well-studied, especially during pregnancy. This pilot study is intended to determine how guided imagery (imagining relaxing scenes) affects blood pressure and anxiety, and to assess how satisfied women are with this technique. Sixty-six pregnant women with high blood pressure will be randomly assigned to (1) listen to a guided imagery audio-compact disc or (2) quiet rest, at least twice-daily for 4 weeks. All women in both groups will receive all usual care, plus will have their blood pressure measured regularly during 1 day per week for 4 weeks. This study will determine if imagery lowers maternal blood pressure, and if further research on imagery effects on pregnancy health outcomes is feasible.
