Filter by: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.
evaluation of the role of ultrasonographic parameters (mean gestational sac diameter, yolk sac diameter, crown rump length, embryonic heart rate and uterine artery Doppler) in predicting early pregnancy failure in patients with recurrent pregnancy loss
Miscarriage occurs in about 1-2% of human pregnancies and is one of the common pregnancy problems before 12 weeks of pregnancy. Anatomical and chromosomal abnormalities, microbial factors and auto and alloimmune reactions have been speculated to attribute in recurrent miscarriage. Unexplained recurrent miscarriage (URM) is defined as three or more repeated abortions, probably caused by maternal immunological rejection . Given that maternal immune system encounters semi-allogeneic fetus, pregnancy outcome is associated with the interaction between maternal immune system and immuno-regulatory capability of the fetus. Effectiveness of treatment approaches in RM patients has been controversial and remained to be discovered. Immunomodulatory agents such as corticosteroids and allogeneic lymphocyte immunization showed variable success rates in RM patients. Therapeutic effects of IVIG in unexplained RM is controversial and most positive results were obtained from the trials in RM women with cellular immune abnormalities, such as increased NK cell level and/or cytotoxicity, and T cell abnormalities. Previous studies have shown that the incidence of genetic abnormalities in children who have received immunosuppressive drugs such as IVIg like normal people and normal society. In this study we used IVIg at the time of positive pregnancy,400 mg/kg IVIG was administered intravenously. Following the first administration, IVIG well given every 4 weeks through 32 weeks of gestation to suppress the immune system in patients with immunological causes of RPL and the results will be compared with a control group that did not receive any type of drug.
The present study is divided into two groups ,one is the patients with subclinical hypothyroidism who has TPO antibody positive women with TSH concentrations > 2.5 mU/L and below the upper limit of the pregnancy specific reference range ,another is TPO antibody negative with TSH concentrations greater than the pregnancy specific reference range and below 10.0 mU/L.The two groups are randomized into either the LT4 treatment group or control group by the use of a computer-generated list. The aim of our study is to determine whether the use of levothyroxine is beneficial in patients with subclinical hypothyroidism in two groups。
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.
In human, 2% of couples experimented Recurrent pregnancy loss (RPL). Currently, while etiological investigations were performed, 40 to 50 % of RPL were unexplained. In animals' studies, several studies have underlined the importance of sperm quality for a normal embryo development. In human, epidemiological studies have demonstrated that several male risk factors have effects on development (male mediated development toxicology). However, few studies have explored sperm DNA fragmentation on embryo development but after in vitro fertilization. In natural pregnancy only rare studies have been performed but with different populations definitions and different methods of sperm exploration. In this context sperm DNA fragmentation exploration appears justified. The present study purpose to conduct a case - control study in order to research paternal role in RPL.
Question: Can implantation failure (IF) be predicted prior to in vitro fertilization (IVF)? A pilot, non-interventional, clinical study Prospective, controlled, cohort study
Recurrent pregnancy loss (RPL) affects 5% of couples trying to achieve parenthood. Most cases of RPL are unexplained and have no effective treatment to improve the likelihood of a pregnancy resulting in a live birth. This leads to significant patient and provider frustration and emotional stress. Hydroxychloroquine (HCQ) is a medication commonly used in pregnancy to treat autoimmune and connective tissue diseases such as systemic lupus erythematosus (SLE). This use has shown that HCQ is very safe in pregnancy. HCQ has anti-inflammatory and anti-thrombotic effects and thus may improve pregnancy outcomes in couples with unexplained RPL. Although some providers are already prescribing HCQ for unexplained RPL, a randomized controlled trial is necessary to determine the true efficacy and safety of this treatment. This study has the potential to establish support for a new treatment option for unexplained RPL.
This is a randomised, double blind, multi-center, placebo-controlled study of subcutaneous NT100 in pregnant women with a history of unexplained recurrent pregnancy loss. Approximately 150 participants will be randomised to receive subcutaneous NT100 or placebo.
