Active clinical trials for "Abortion, Spontaneous"

Development of mole was not associated with segregation of mutated NLRP7 allele in the haploid oocyte. We hypothesize NLRP7 is a maternal factor involved in regulating early embryo development or embryo-uterine interaction. In the proposed study, we seek to identify novel genetic variants and mutations of NLRP7 in women who experienced RM/HM. Genetic association study and haplotype analysis are performed to test assocation between NLRP7 gene and female reproductive performance. Immunohistochemical staining, RT-PCR, and Western blot analysis are used to investigate expression pattern of NLRP7 in endometrium and placenta. Two approaches are used to characterize functional significance of genetic variants/mutations. The first approach will be based on mutagenesis and the second approach will be based on induced pluripotent stem cells (iPSCs). Results obtained from the proposed study will provide novel insight into mechanism of embryo development and implantation.

Recurrent pregnancy loss (RPL) is a clinical problem affecting 1-5% of couples of reproductive age. The contribution of thrombophilia to RPL is disputed. This controversy is partly due to low sensitivity of the genetic variants currently used to evaluate hereditary thrombophilia: the Leiden mutation (identified as rs6025) in the coagulation factor 5 (F5L) gene and mutation G20210A (identified as rs1799963) in the prothrombin (PT) gene. Our objective was to determine whether a wider algorithm that includes clinic and genetic variants associated with thrombophilia could be more useful in the prediction for RPL than FVL and PT alone.

evaluation of serum CA125 level and yolk sac morphology in women with threatened miscarriage is very important to predict pregnancy outcome

This study seeks to evaluate pregnancy outcomes following hysteroscopic uterine cavity expansion surgery for patients with dysmorphic uterine cavities and poor reproductive histories. Patients already planning to undergo surgery at the recommendation of their physicians will be recruited for participation.

This is a randomised controlled trial designed to investigate the impact of a brief-cognitive task based intervention on intrusive memories, mental health symptoms and daily functioning, in women following an early pregnancy loss.

Women presenting to Washington Hospital Center with fetal loss would be offered participation in the study. The objective is to determine if ccffDNA obtained from maternal blood is present in the setting of missed abortion or fetal demise. The investigators primary hypothesis is that cell free fetal DNA will be present in maternal blood in the presence of a failed pregnancy.

This study will assess the risk of spontaneous abortion during weeks 1-23 and weeks 1-19 of gestation, respectively, and other pregnancy outcomes, in an exposed cohort, i.e. women with last menstrual period (LMP) between 30 days before and 45 days after, or 30 days before and 90 days after any dose of Cervarix, when compared to a non-exposed cohort, i.e. women with LMP between 120 days and 18 months after the last Cervarix dose. The data collected in the Clinical Practice Research Datalink General Practitioner OnLine Database (CPRD GOLD) in the UK, will be analysed in this study.

Chronic endometritis is a persistent inflammation of the endometrium. Chronic endometritis is asymptomatic or little symptomatic. Sometimes, patient with chronic endometritis can have genital bleeding, pelvic chronic pain, pain during sexual relations, persistent vaginal white loosing. The hysteroscopy can detect the presence or absence of chronic endometritis. Some studies showed that the endometritis could have an impact on the embryo implantation and could explain recurrent miscarriages or repeated embryo implantation failures. The goal of this study is to evaluate the frequency of the chronic endometritis in patients with recurrent miscarriages or repeated embryo implantation failures

To be diagnosed with recurrent miscarriages, a couple might have a child, however experiences three or more miscarriages, primarily this happens during the first trimester. These miscarriages often needs medical evacuation or a D & C. Surgery or retained tissue increases the risk of complications as infection and/or adhesions, known as asherman syndrome, which may result in subfertility. Recently chronic infection in the endometrium has been proposed to contribute to the condition, as protocols including treatment with antibiotics have led to birth at term for some of these women. Using the very minimal invasive office hysteroscopy, the investigators aim to describe the uterine cavity in patients diagnosed with recurrent miscarriages regarding both abnormalities in the endometrium and chromic infection.

To assess natural killer cells frequency and activation in cases of unexplained recurrent abortion in comparison to fertile cases 2. . To study the expression of stimulatory receptors of natural killer cell. 3-To study the expression of inhibitory receptors of natural killer cell.
