Filter by:Recurrent pregnancy loss (RPL) affects around 5 % of women in reproductive age. The underlying cause of RPL is most often unknown, probably multifactorial, and no treatment with documented effect on chance of live birth exists. In unexplained cases of RPL, primarily the immune system is hypothesized to play a pivotal, causative role, since autoantibodies and specific human leukocyte antigen (HLA) alleles as well as unbalanced distribution of leucocyte subsets, especially natural killer (NK) cells and T-helper (Th) cells, occurs more frequently in patients with unexplained RPL. For that reason, many treatment regimens used in autoimmune diseases have been tested on RPL patients, as for example prednisolone and intravenous immunoglobulin (IVIg). IVIg (Privigen) consist of a broad spectrum of structurally and functionally intact IgG antibodies. The mechanism of action is not fully elucidated, but certainly IVIg do help opsonise and neutralize foreign cells and pathogens. Prednisolone support this anti-inflammatory action by suppressing migration of polymorphonuclear leukocytes, and reducing the volume and activity of the immune system and the capillary permeability. A retrospective, observational pilot study suggested that a combination of prednisone and IVIg in first trimester improves the chance of a live birth in women with RPL after assisted reproductive technologies (ART) (Nyborg et al., 2014). A randomized controlled study is necessary for determining if this immunomodulatory treatment definitely is effective in patients with unexplained RPL after ART (defined as IVF or ICSI ad FER). Potentially, this study will be able to establish evidence for an effective treatment to women with unexplained RPL after ART, who otherwise have a poor prognosis.
STUDY AIM: to study the pregnancy outcomes and offspring development of patient with Unexplained Recurrent Pregnancy Loss Treated by PGS and spontaneous pregnancy, and to compare the health economic indicators and patient satisfaction of the two modes of pregnancy, so as to better guide the clinical treatment.
For many years there is a lack of large randomized controlled trials that study the effect of low dose prednisone in women with RPL and thus the evidence of a probable efficacy of prednisone in RPL women remains limited and unclear. As the ESHRE recommended in 2018 (2) we aim to assess the effect of such treatment in a large trial that includes unexplained and abnormal autoimmune profile RPL patients. we also aim to assess the side effects of the treatment in RPL pregnant women.
Biochemical pregnancy loss (BPL) is a very frequent issue in human reproduction. After the implantation of the embryo, hCG disappears very soon from the maternal bloodstream and no evidence of a clinical pregnancy is seen. Different studies showed that factors such as age, oocyte and embryo quality, and endometrium receptivity may have something to do with the occurrence of biochemical pregnancy loss post assisted reproduction treatment. The main aim of this study is to evaluate the incidence of biochemical pregnancy loss (BPL) in three different cohort populations; patients undergoing frozen embryo transfer (FET) from own oocytes after preimplantation genetic testing for aneuploidy (PGT-A), patients undergoing FET from own and donated oocytes and with endometrial receptivity array (ERA), and patients undergoing FET from own or donated oocytes (without PGTA or ERA test). We will analyse the incidence of BPL in these populations and try to determine the role of the euploid status embryo in the first group, the endometrium in the second group and the third one as control group. We are waiting to find the value of both players in the origin of BPL.
To evaluate endoplasmic reticulum stress in women with recurrent pregnancy loss and those who had healthy births in the same age group. The level of the unfolded protein X box binding protein 1 (XBP-1) is measured. It is aimed to show the effect of endoplasmic reticulum stress on recurrent pregnancy loss.
This study aims to determine the effect of the Healthwise decision aid on shared decision making in women undergoing management of early pregnancy loss.
Clinical research will be carried out on two groups of patients. It will be performed on people with recurrent pregnancy loss and without a history of pregnancy loss. In two groups, blood samples will be assessed by elisa test, SCUBE-1 level and carotis intima media thickness will be evaluated by ultrasonographic measurement. It will be investigated whether there is a statistically significant difference between the two groups.A statistically significant difference in SCUBE-1 and carotid intima media thickness known as ischemia markers is expected in the group with recurrent pregnancy loss that could not be explained in the hypothesis of this planned study.
This will be a retrospective observational cohort study utilizing the data from the British Columbia Perinatal Data Registry (BCPDR). The BCPDR is a provincially inclusive database that aggregates obstetrics and neonatal variables from all attended births in British Columbia. The primary objective of this study is to evaluate and contrast the average time interval from the first to second birth for patients with recurrent pregnancy loss compared to healthy controls. Secondarily, the investigators will calculate the cumulative live birth rate in the cohort of women with recurrent pregnancy loss who were </= 35 at age of first birth and delivered between the years 2000-2010. Finally, the investigators will compare the incidence of adverse perinatal outcomes for those with recurrent pregnancy loss and those without. The results of this study will be valuable for clinicians and patients as it will provide information for prognosis counselling. This will also help those desiring more than one child with long term family planning.
All stillbirths in Stockholm during 2017 were analysed according to the primary outcomes which were preventable/non-preventable deaths and the level of delay. The secondary outcomes were: causes of death, standard of care pre and post stillbirth and if a summary of the possible causes of death was made as well as the planning of supervision of the next pregnancy.
The DEFI-1 study recruited 625 women witnesses and 299 of their spouses. With regard to case couples, 271 cases were recruited from the spontaneous repeated miscarriages (SRM) subgroup (≥3 spontaneous miscarriage (SM) from trimester 1 of pregnancy) and 93 from the unexplained fetal death in utero (FDIU) subgroup from trimesters 2 and 3 of pregnancy. The main objective of the DEFI 2 study is to increase the number of case-pairs in these 2 particular subgroups to replicate the results of the genetic determinants highlighted from cases and controls with extreme phenotypes and obtain a sufficient number of women with FDIUs to identify specific determinants.
