Active clinical trials for "Abortion, Habitual"

This is a pilot study with the aim to investigate the beneficial effect of bicarbonate buffered medium containing hyaluronan and recombinant human albumin (EmbryoGlue®, Vitrolife) in patients with documented repeated implantation failure on live birth per randomized subject as primary endpoint.

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.

This study aims to investigate the role of uNK cells and the association with prednisolone.

In 50% of women with recurrent pregnancy loss (RPL) miscarriages are unexplained, therefore no therapeutic intervention is possible. In a pilot study, women with unexplained RPL showed less endometrial NK cells (eNK) compared to women with a previously uncomplicated pregnancy. It is known that eNK cells are important for embryo implantation during early pregnancy. Investigators presume that high sympathetic activity in these women is related to eNK cell number, function and phenotype and that exercise is an effective intervention to lower sympathetic activity and to influence the immune system, as especially peripheral NK cells have been assumed to be responsive to physical training. The investigators hypothesize that moderate exercise can lower the adrenergic tone of the sympathetic nervous system hereby influencing endometrial NK cells in women with RPL and eventually pregnancy outcome.

Spontaneous pregnancy loss is a relatively common phenomenon, with 10-15% of clinically recognized pregnancies ending in miscarriage.1 Recurrent pregnancy loss (RPL) is a disorder defined by two or more failed pregnancies2. According to various studies, pregnancy loss has been described as a traumatic event for couples even if the loss occurs at a very early stage of pregnancy. Few controlled studies dealt with the effects of the miscarriage on the psychological condition of women during a subsequent pregnancy, 4,6-8. This study aimed to evaluate the effectiveness of "at home ultrasound" in addition to routine prenatal care in reducing maternal anxiety during pregnancy for patients with history of recurrent pregnancy loss. i.

Recurrent miscarriage (RM) defined by >=3 consecutive losses affects 1% of fertile couples. Most women have recurrent early loss with a failure of development before 10 weeks' gestation. Standard investigations fail to reveal any apparent cause in >50% of couples. No study has demonstrated any benefit of any medication in women with Unexplained RM, in the presence or absence of an inherited thrombophilia. Moreover, the benefit of aspirin and/or heparin has not been proved in women with Antiphospholipid (APL) antibody without other clinical manifestations of Antiphospholipid Syndrome. Hydroxychloroquine (HQ) is a molecule whose properties (anti-thrombotic, vascular-protective, immunomodulatory, improved glucose tolerance, lipid-lowering, anti-infectious) could be useful against mechanisms of Unexplained RM. There is no data concerning the benefit of HQ in RM in the presence or absence of antiphospholipid antibodies or any inherited thrombophilia. Administration in (Systemic Lupus erythematosus (SLE) women and for Malaria prevention provides extensive safety data during pregnancy. Oral administration makes possible treatment since the preconception period. For all of that and its low cost, hydroxychloroquine should be evaluated in RM whatever the woman thrombophilic status.

The purpose of this study is to demonstrate the ability of low dose IL-2 to stimulate peripheral blood Tregs of women with unexplained repeated early spontaneous miscarriages for development of a therapy to prevent fetal rejection by low dose IL-2.

Objective To determine maternal and fetal outcomes in women with Unexplained RPL managed with aspirin or unfractionated heparin (UFH) plus aspirin during pregnancy. Design: prospective clinical controlled study. Setting: high-risk pregnancy unit- Benha university hospital. Methods: Pregnant women with unexplained recurrent miscarriage attending high-risk pregnancy unit. 200 selected patients with previous unexplained recurrent miscarriage are divided into 2 groups: group A (n = 100) receive low-dose aspirin (81 mg once daily orally) plus heparin (5000 IU) every 12 h with the first positive pregnancy test while group B (n = 100) receive no thing . Main outcome measures: Maternal outcomes included thromboembolic and haemorrhagic complications and pregnancy-induced hypertension .Prematurity, intrauterine growth restriction and neonatal death were considered as maternal and fetal complications

Blastocysts derived from patients seeking infertility treatment were generated by in vitro fertilization and embryo culture as previously described, and were evaluated using the Gardner system. As part of the embryo selection process, cells of TE biopsy were collected, and blastocysts were vitrified. The clinical TE biopsies were subjected to whole genome amplification (WGA) with SurePlex reagents (Illumina) followed by NGS-based PGT-A using Illumina's VeriSeq kit (Illumina) on a MiSeq system (Illumina) according to the manufacturer's protocol.
