NCT ID: NCT04718233 Completed - Clinical trials for Recurrent Pregnancy Loss

Effect of Sildenafil Citrate on Mid Luteal Phase Uterine Artery Blood Flow in Patients With Recurrent Pregnancy Loss

Start date: September 5, 2018
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT04709796 Not yet recruiting - IVF Clinical Trials

The Use of High Concentration Hyaluronic Acid (HA) Transfer Medium in Repeated Implantation Failure (RIF) Patients

Start date: January 2021
Phase: N/A
Study type: Interventional

This is a pilot study with the aim to investigate the beneficial effect of bicarbonate buffered medium containing hyaluronan and recombinant human albumin (EmbryoGlue®, Vitrolife) in patients with documented repeated implantation failure on live birth per randomized subject as primary endpoint.

NCT ID: NCT04701034 Not yet recruiting - Miscarriage Clinical Trials

Intravenous Immunoglobulin and Prednisolone for RPL After ART.

Start date: January 6, 2021
Phase: Phase 2
Study type: Interventional

Recurrent pregnancy loss (RPL) affects around 5 % of women in reproductive age. The underlying cause of RPL is most often unknown, probably multifactorial, and no treatment with documented effect on chance of live birth exists. In unexplained cases of RPL, primarily the immune system is hypothesized to play a pivotal, causative role, since autoantibodies and specific human leukocyte antigen (HLA) alleles as well as unbalanced distribution of leucocyte subsets, especially natural killer (NK) cells and T-helper (Th) cells, occurs more frequently in patients with unexplained RPL. For that reason, many treatment regimens used in autoimmune diseases have been tested on RPL patients, as for example prednisolone and intravenous immunoglobulin (IVIg). IVIg (Privigen) consist of a broad spectrum of structurally and functionally intact IgG antibodies. The mechanism of action is not fully elucidated, but certainly IVIg do help opsonise and neutralize foreign cells and pathogens. Prednisolone support this anti-inflammatory action by suppressing migration of polymorphonuclear leukocytes, and reducing volume of the immune system, capillary permeability, and immune cell activity. A retrospective, observational pilot study suggested that a combination of prednisone and IVIg in first trimester improves the chance of a live birth in women with RPL after assisted reproductive technologies (ART) (Nyborg et al., 2014). A randomized controlled study is necessary for determining if this immunomodulatory treatment is definitely effective in patients with unexplained RPL after ART (defined as IVF or ICSI treatment). Potentially, this study will be able to establish a new treatment to women with unexplained RPL after ART, who otherwise have a poor prognosis.

NCT ID: NCT04643938 Completed - Clinical trials for Recurrent Early Pregnancy Loss

PGT-A in Screening of Embryos in the Treatment of Unexplained Recurrent Miscarriage

Start date: January 1, 2020
Study type: Observational

uRM patients selected PGT-A from 2012 to 2016 were included in this study. Their clinical outcomes were prospectively observed and analyzed to explore the factor influenced the outcomes.

NCT ID: NCT04624269 Not yet recruiting - Clinical trials for Antiphospholipid Syndrome

A Study of Hydroxychloroquine Sulfate in the Treatment of Recurrent Spontaneous Abortion With Antiphospholipid Syndrome

Start date: December 1, 2020
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT04621773 Active, not recruiting - Clinical trials for Recurrent Pregnancy Loss

Live Birth Rate in Patients With Unexplained Recurrent Pregnancy Loss

Start date: September 1, 2020
Study type: Observational [Patient Registry]

STUDY AIM: to study the pregnancy outcomes and offspring development of patient with Unexplained Recurrent Pregnancy Loss Treated by PGS and spontaneous pregnancy, and to compare the health economic indicators and patient satisfaction of the two modes of pregnancy, so as to better guide the clinical treatment.

NCT ID: NCT04558268 Not yet recruiting - Clinical trials for Recurrent Miscarriage

Low Dose Prednisone Therapy in Women With Recurrent Pregnancy Loss

Start date: December 2020
Phase: Phase 2/Phase 3
Study type: Interventional

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.

NCT ID: NCT04544462 Enrolling by invitation - Infertility Clinical Trials

ANXA5 M2 Haplotyping in IVF Patients and Embryos

Start date: February 10, 2020
Study type: Observational

This study aims to characterize the association between history of pregnancy complications and M2 carrier status in IVF patients and the utility of M2 haplotype preimplantation genetic testing (PGT) in embryos produced by carrier couples. Participants in this study will be screened for the M2 variant. History of pregnancy complications and miscarriages will be studied in order to determine potential associations with M2 carrier-ship.

NCT ID: NCT04455256 Completed - Clinical trials for Recurrent Pregnancy Loss

Evaluation of Endoplasmic Reticulum Stress in Patients With Recurrent Pregnancy Loss

Start date: March 20, 2020
Study type: Observational

To evaluate endoplasmic reticulum stress in women with recurrent pregnancy loss and those who had healthy births in the same age group. The level of the unfolded protein X box binding protein 1 (XBP-1) is measured. It is aimed to show the effect of endoplasmic reticulum stress on recurrent pregnancy loss.

NCT ID: NCT04397042 Completed - Clinical trials for Recurrent Pregnancy Loss

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

Start date: May 22, 2020
Study type: Observational [Patient Registry]

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.
