To investigate efficacy and safety of Hydroxychloroquin in improving pregnancy outcome in women with unexplained recurrent pregnancy loss .
Lower Apelin levels are associated with hypertensive disorders with pregnancy, yet no studies investigated its levels in recurrent pregnancy loss
This multinational, prospective, active surveillance, registry study following two cohorts will include study participants who are pregnant and seeking any type of medical treatment, including dydrogesterone and other progestogens, for either (A) recurrent pregnancy loss and/or bleeding in early pregnancy or (B) as In-Vitro Fertilization (IVF)/Assissted Reproductive Technology (ART) support. Pregnant women not taking progestogen and are advised an alternative non-medical treatment, in the context of bleeding in early pregnancy, recurrent pregnancy loss, or undergoing natural cycle frozen embryo transfer (NC-FET) can also be included in this study. Eligible study participants will be recruited via an international network of prescribing Health Care Practitioners (HCPs) in China, Turkey, and Russia with the aim to collect data related to maternal safety and newborn safety in women prescribed progestogens during early pregnancy. Study participants will be followed from early pregnancy until 6 - 12 weeks after giving birth. All malformations will be captured via direct contacts with the study participants. Study participants will be sent online questionnaires via the electronic Patient Reported Outcomes (ePRO) solution provided by MediData. Major malformations reported by the study participants will be validated by ZEG Berlin via relevant source documents and if necessary, via contacting the treating HCPs. The total study duration is planned for approximately 4 years including recruitment and follow-up.
Recurrent pregnancy loss (RPL) is a refractory disease with diverse etiologies, complex pathogenesis and limited therapeutic options. Current tests and treatments lack uniform specifications. This study is a prospective clinical cohort study which intends to screen out meaningful examination items and reliable and effective treatment. The study content includes (1) tracking the re-pregnancy information of patients with initial inevitable abortion, comparing the clinical data and examination test results between patients with single abortion and RPL, and (2) comprehensively and systematically screening the patients with initial inevitable abortion, taking those without obvious abnormalities and those with a re-pregnancy into the control group and taking those with a re-pregnancy after abnormal findings were treated into the study group, recording the pregnancy and perinatal conditions of the two groups, comparing the pregnancy outcomes of the two groups, and analyzing the risk factors for RPL. The results of this study will establish a model of maternal and newborn risk assessment for first trimester medication use and provide strong evidence-based evidence to clarify the diagnosis and treatment processes of RPL.
A low plasma level of mannose binding lectin (p-MBL) is associated with unexplained recurrent pregnancy loss (RPL), but it is not investigated if it is associated with unexplained reproductive failure in general, including recurrent implantation failure (RIF) after assisted reproductive technology (ART) (including IVF, ICSI and FET), recurrent pregnancy loss (RPL) after spontaneous conception, and RPL after ART.
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.
This prospective nested case-control study aims to examine the effects of blood vitamin B levels in first-trimester pregnant women on the pregnancy outcomes
This research is being done to determine if using a microfluidics chamber, a device used to process sperm, will be effective in improving the rates of embryos with normal chromosomes (structures that carry genetic information) during in vitro fertilization (IVF) treatment. The investigators hypothesize that this device is effective at improving rates of normal chromosomes among embryos.
Patients with recurrent pregnancy loss are known to have decreased uterine artery blood flow. Nitric oxide plays a major role in increasing uterine blood flow during the luteal phase. This study is done to evaluate the effects of sildenafil on blood flow indices in the patients with recurrent pregnancy loss due to impaired uterine artery blood flow.
