Rationale: Recurrent pregnancy loss (RPL) is defined as the loss of two or more conceptions before the fetus reaches viability. It affects 1-3% of all fertile couples and despite extensive diagnostic work-up, in only around 30% an underlying cause is identified. Several factors may increase the risk for miscarriage, but the chance of a normal, successful pregnancy is still high. So, in supporting couples with RPL, an important part of the clinical management of these couples is to provide couples with accurate prognoses for their next pregnancy. The main limitation in current prediction models is the lack of a sufficiently large cohort, adjustment for relevant risk factors such that prognoses are individualized, and separating between the cumulative live birth rate and the chance that the next conception will lead to a live birth. In this project therefore we aim to make an individualized prognosis regarding the future chance of live birth and the chance of a healthy child. This could then lead to improved wellbeing and the ability of making future reproductive choices. Objectives: Primary objective: to predict the chance of a live birth within three years after intake in couples with unexplained RPL Secondary objectives: - to predict the chance of an ongoing pregnancy (>12 weeks) in the next pregnancy in couples with unexplained RPL. - to predict the chance of a complicated pregnancy in couples with unexplained RPL - to predict the chance dynamically of a live birth given the outcome of a pregnancy after intake - to predict the chance of above outcomes in couples with a known cause for RPL Study design: A multicenter retrospective and prospective cohort study. Study population: Couples with females aged ≤42 years in both prospective and retrospective inclusion. Retrospective inclusion: Couples with RPL who visited the RPL outpatient clinic in participating centers from 2006 until the start of this study. Prospective inclusion: new couples with RPL who will visit the clinic from 2021 onwards. Main study parameters/endpoints: - Pregnancy outcomes since intake - Time to pregnancy since intake - Time between pregnancies since intake - Pregnancy complications since intake - All outcomes will be obtained up to a maximum of five years after intake - Patient characteristics: cause for RPL, female age, male age, previous live birth, duration of RPL (since diagnosis) Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Participating in this study does not yield any risks. There could be a burden in case of retrospectively collecting data. Participating does not yield direct benefits for the subjects, however it may lead to future improvements of care for couples with RPL.
The efficacy of low-dose aspirin combined with low-molecular-weight heparin treatment for improving antiphospholipid syndrome and maternal-fetal outcome of patients is recognized by various countries and recommended by the guidelines. However, there are still 20-30% of APS patients whose treatment fails. Therefore, the standard treatment effect is still not ideal, and other treatment options need to be explored. The purpose of this study is to conduct a randomized double-blind, parallel controlled study of patients with recurrent miscarriage and APS in addition to standard treatment, plus hydroxychloroquine sulfate (HCQ) or placebo, to observe the effects of HCQ on pregnancy outcome in patients with abortion and APS, to evaluate the effectiveness and safety of HCQ 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.
1. To evaluate histopathological findings of products of conception in both sporadic and recurrent miscarriage. 2. To determine the prevalence of chronic histiocytic intervillositis in both sporadic and recurrent miscarriage.
It is a case-control study composed of 3 groups : 2 cases groups (RIF and IRPL) already composed as part of a pre-existing research project and 1 control group including patients undergoing ART for male factor infertility. The purpose of this study is to compare the 2 case group with the control group to identify metabolomics signatures.
Recurrent miscarriage is a pregnancy loss before 20 weeks of gestation. The recurrent pregnancy loss(RPL) usually occurring in the first trimester of gestation and its rate is quite high (15-20% even in full reproductive period) . In 2012, the American Society for Reproductive Medicine Practice Committee issued a statement that defined recurrent pregnancy loss as a disease distinct from infertility defined by two or more failed consecutive pregnancies.approximately 40% of couples will have an etiology identified that could be associated with their loss.
Evaluating the effect of intralipid on the natural killer cells
The purpose of this study is to determine whether Cyclosporin A (CsA) - an immunosuppressant drug - in early pregnancy will reduce the risk of miscarriage in women who had a history of unexplained recurrent miscarriages, as compared with that treated with Dydrogesterone-an active comparator. The hypothesis is based on the evidence found in vitro and in vivo experiments that CsA can induce maternal-fetal tolerance so that it may reduce the risk of miscarriage.
