View clinical trials related to Recurrent Pregnancy Loss.
Filter by:Recurrent pregnancy loss (RPL) defined as 3 or more pregnancy losses affects approximately 3% of couples trying to achieve parenthood. Most cases of RPL are unexplained and have no effective treatment to improve the chance of a live birth. Exciting indications for using Hydroxychloroquine (HCQ) include: Malaria profylaxis and treatment, systemic and discoid lupus erythematosus (SLE) and rheumatoid athritis (RA). HCQ has been reported to have the following properties (anti-thrombotic, vascular-protective, immunomodulatory, improving glucose tolerance, lipid-lowering, and anti-infectious). There is no data concerning the benefit of HCQ in RPL. Administration for other indications provides extensive safety data during pregnancy. This study has the potential to establish support for a new treatment option for unexplained RPL.
50%-60% of the known causes of recurrent pregnancy loss(RPL) are associated with embryonic aneuploidy, such that preimplantation genetic screening (PGS) on embryos acquired by assisted reproductive treatment should improve the rate of pregnancy and live birth in those patients. In dispute though the clinical application of PGS has been, a series of studies show that the new generation of PGS(PGS 2.0), based on blastocyst biopsy followed by whole genome analysis, has significantly improved the clinical outcome of IVF treatment. At present, there is still a need for the evidence of the use of PGS 2.0 in RPL patients, who may benefit from this emerging technology considering the prevalence of genetic abnormalities and the number of transferable embryos in this population. An earlier single center RCT conducted by our IVF center displayed higher implantation rate, clinical pregnancy rate and ongoing pregnancy rate calculated by per embryo transfer(ET) cycle in IVF/ICSI+PGS group compared with IVF/ICSI group. This multi-center prospective randomized clinical trial is to provide more data to determine whether the clinical outcomes are significantly improved per treatment cycle such that provide evidence for the application of PGS in RPL patients. Besides, risk factors of PGS outcome are to be analyzed from multi-center data to build a model for prediction of the possible outcomes of PGS and direction of the clinical choice.
In this clinical cohort study, the investigators are going to observe the efficacy of anti-coagulation and immune therapy in the treatment of recurrent pregnancy loss with a prospective randomized controlled trial.
RSA is a multifactorial disorder resulting from genetic factors, anatomic factors, autoimmune disorders, endocrine dysfunction, thrombophilia, life style factors, and maternal infections. However, the underlying causes remain undetermined in up to 50% of cases. In this clinical cohort study, we intended to get an epidemiological evidence for patients with recurrent spontaneous abortion associated with thrombophilla.
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
We propose to perform a clinical randomized trial to evaluate the effect of blastocyst biopsy and whole chromosome analysis by Next Generation Sequencing (NGS) in comparison to standard Assisted Reproductive Technologies (ART) methods on on implantation rates, miscarriage rates, and pregnancy rates. This will be three studies into one: a) a comparison of treatment (NGS) and no treatment, b) a non-selection study based on the control group for which we will replace without knowing the ploidy of the embryos, but we will know it later, c) a retrospective study about the use of Mitochondrial DNA as a selection tool.
The study will compare the effect of Aspirin versus clopidogrel effect on uterine perfusion in women with unexplained recurrent pregnancy loss with decreased uterine artery pulsatility index. Null hypothesis: Women with recurrent miscarriage have the same blood flow after aspirin or clopidogrel treatment compared to their uterine artery pulsatility index before treatment.
