Active clinical trials for "Abortion, Habitual"

The purpose of this Registry is to prospectively collect data of Recurrent Pregnancy Loss (RPL) patients attending the specialized care centre at the BC Women's Hospital, in order to evaluate investigation practices, treatment options, and outcomes for this patient population over time.

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.

The overall goals of this proposal are to determine the genetic architecture of recurrent pregnancy loss (RPL) and to discover genomic predictors of RPL.

To compare the livebirth rate of women with recurrent pregnancy loss and autoantibodies randomized to either low molecular weight heparin plus aspirin versus aspirin alone.

Overweight and obesity has been associated with a number of adverse pregnancy outcomes in women of reproductive age, including infertility and early pregnancy loss. Recent data suggests that overweight and obese patients are also at increased risk of recurrent pregnancy loss (RPL), a devastating condition that affects 1% of the fertile population. The investigators propose a prospective, randomized controlled trial in which overweight and obese patients with unexplained recurrent pregnancy loss are enrolled in a structured, 6 month, weight loss program or provided routine counseling regarding the importance of weight loss. Pregnancy outcomes will then be followed to assess miscarriage rates. Metabolic outcomes, such as lipid and glucose profiles, will also be evaluated.

Recurrent spontaneous abortion (RSA) is a common pregnancy complication in women of reproductive age and the cause of RSA remains largely unclear. Acupuncture is widely used in clinical practice to treat infertility and abortion. The role of acupuncture in the treatment of infertility is still unclear. The investigators conducted a randomized, prospective, controlled clinical trial to investigate its potential impact on pregnancy outcome. Herein, the investigators not only evaluated the changes in patients' psychological stress before and after treatment but also followed up on pregnancy outcomes. In addition, changes in uterine artery blood flow were observed by ultrasound. Changes in coagulation-related indicators were also detected.

Recurrent miscarriage(RM) and recurrent implantation failure (RIF) are clinical challenge for clinicians and patients who are desperate for a healthy child.The specific etiology contains chromosomal abnormalities, reproductive anatomical abnormalities, endocrine disorders, reproductive system infections, autoimmune and environmental factors. However there are still 50% to 60% RM and RIF which don't have a clear cause,mainly associated with alloimmune factors.Among various treatments,lymphocytes active immunotherapy is the most common treatment method, and its clinical efficacy is widely recognized although its action mechanism is not clear so far.

EmbryoGen and BlastGen contain the cytokine growth factor Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF), which has been documented to give significant benefit to this difficult group of patients. Results showed a highly significant effect of 44% relative improvement in ongoing implantation rate (p=0.001) in women who have previously miscarried (Ziebe et al 2013). We wish to undertake a randomised Controlled trial to determine if EmbryoGen/BlastGen media improves pregnancy outcomes in women with recurrent implantation failure, recurrent miscarriage and poor embryo development when compared to standard media.

Two groups of unexplained recurrent spontaneous abortion, each included 65 participants. scheduled randomly into; the study group received Sildenafil Citrate and Placebo group. The intervention started from day 21-23 of the cycle preceding spontaneous pregnancy and continued till the 12th-week of gestation. The primary outcome measure was the difference in the live birth between both groups. Secondary outcome measures were the differences between both groups regard pulsatility index (PI) and resistance index (RI), a number of take-home babies, the reported side-effects of treatment and the pregnancy-related complications.

Recurrent unexplained spontaneous miscarriage (RSM) is defined as three consecutive pregnancy loss prior to 20 weeks from the last menstrual period. 1% to 2% of women experience RSM. Treatment of URSM is a challenging issue. The currently available lines of treatment according to simplicity of use, reliability and degree of invasiveness include corticosteroids, sildenafil citrate, aspirin, heparin and immunoglobulins (besides good antenatal care), but up to now there are no prospective randomized studies, powerful enough, to determine a significant difference between these therapeutic protocols, with any of the above mentioned pharmacological agents. Sildenafil Citrate (Viagra®), a vasodilator, is also described as an anti-inflammatory agent. While improving uterine blood flow in the proliferative phase, NO may have detrimental effects at the level of the endometrium during the implantation window. The NO- mediated release of cytokines such as tumour necrosis factor- from activated natural killer cells has been implicated as a cause of implantation failure. Based on these observations, this study attempts was made to study uterine arteries and sub-endometrial blood flow during the luteal phase in normal fertile women and in patients with Unexplained recurrent miscarriage
