SCUBE-1 and Carotid Intima Media Thickness in Recurrent Pregnancy Loss

Recurrent Pregnancy Loss

Clinical research will be carried out on two groups of patients. It will be performed on people with recurrent pregnancy loss and without a history of pregnancy loss. In two groups, blood samples will be assessed by elisa test, SCUBE-1 level and carotis intima media thickness will be evaluated by ultrasonographic measurement. It will be investigated whether there is a statistically significant difference between the two groups.A statistically significant difference in SCUBE-1 and carotid intima media thickness known as ischemia markers is expected in the group with recurrent pregnancy loss that could not be explained in the hypothesis of this planned study.

Hydroxychloroquine (HCQ) for Recurrent Pregnancy Loss

Recurrent Pregnancy LossMiscarriage

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.

On Pregnancy After Losses - OPAL Study

Recurrent Pregnancy Loss

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.

HOPE Trial hCG or Progesterone Effect on Recurrent Pregnancy Loss

Recurrent Pregnancy Loss Without Current Pregnancy

Up to half of all cases of recurrent pregnancy loss are unexplained (uRPL). Evidence points towards endometriosis and progesterone resistance as an underlying cause of uRPL. Previous non-RCT studies have suggested the luteal hCG provides a useful treatment for uRPL. We propose performing a randomized controlled trial to compare mid-luteal hCG with oral progesterone to prevent early pregnancy losses. the endpoint will be ongoing pregnancy and live birth rates. Equal numbers of patients will be randomized to each group.

The Role of Uterine NK Cells and T Cell Cytokines in Recurrent Miscarriage

Recurrent Pregnancy Losses

The aim of the study is to evaluate the role of uterine natural killer cell(uNK)in recurrent pregnancy losses and the correlation between the numbers of it and embryo toxicity by measuring the level of the Th2 cytokines in normal reproductive profile and in patients with Recurrent Pregnancy Losses (RPL).

Uterine Microbiome in Recurrent Pregnancy Loss

Recurrent Pregnancy LossNot Pregnant1 more

The female genital tract microbiome may reflect female reproductive health and may be related to pregnancy outcomes. Disturbances in this microbiome may be associated with adverse reproductive outcomes. The investigators hypothesize that the endometrial and vaginal microbiome composition in women with a history of recurrent pregnancy loss are different, compared with those in normal fertile women.

Nursing Counseling on Stress and Depression for Women With Recurrent Miscarriage

Care in Women With History of Recurrent Miscarriage

Recurrent miscarriage is a frustrating event for couples. The purpose of this randomized, controlled trial was to examine the effectiveness of nursing counseling on sleep quality, depression, stress, and social support in women with recurrent miscarriage (RM). Sixty-two eligible women were randomly assigned to the experimental group (n = 31) or the control (n = 31) group. The experimental group received routine care and three sessions of nursing counseling during the 12-week prenatal genetic testing stage, while the control group received routine care only. Outcome measures included the Pittsburgh Sleep Quality Index, Edinburgh Prenatal Depression Scale, Perceived Stress Scale, and Interpersonal Support Evaluation List. Paired sample t-tests were conducted before and after nursing counseling to measure whether there were any statistically significant changes in outcome variables.

Sperm DNA Fragmentation in Recurrent Pregnancy Loss

RECURRENT PREGNANCY LOSS

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.
