BACKGROUND: Recurrent pregnancy loss (RPL) or recurrent spontaneous abortion is an obstetric complication that affects couples at reproductive age. Previous reports documented a clear relationship between parents with chromosomal abnormalities and both recurrent miscarriages and infertility. However, limited data is available from the Arabian Peninsula which is known by higher rates of consanguineous marriages. The main goal of this study was to determine the prevalence of chromosomal abnormalities and thrombophilic polymorphisms, and to correlate them with RPL and consanguinity in Saudi Arabia...

BACKGROUND: Polymorphisms which are presented below may be the cause of inherited thrombophilia and may result in pregnancy loss. The hypothesis is based on a number of cardiology studies which have confirmed the involvement of these polymorphisms in thrombotic incidents. OBJECTIVES: To evaluate the role of polymorphisms of factor VII gene (Arg353Gln, -122T > C) and PAI-1 gene (-675 4G/5G) in the etiology of recurrent miscarriage. MATERIAL AND METHODS: The study group included 152 women with a positive history of ≥ 2 consecutive pregnancy losses (114 and 38 women with 2 and ≥ 3 miscarriages, respectively), while 180 healthy women were recruited as controls...

Lipopolysaccharide (LPS) injections during pregnancy are well established as models for pregnancy complications, including fetal growth restriction (FGR), thrombophilia, preterm labor and abortion. Indeed, inflammation, as induced by LPS injection has been described as a pivotal factor in cases of miscarriage related to placental tissue damage. The phosphodiesterase-5 inhibitor sildenafil (Viagra®) is currently used to treat FGR cases in women, while low-molecular weight heparin (Fragmin®) is a standard treatment for recurrent miscarriage (RM)...

Thrombophilia is a group of inherited and acquired coagulation disorders often associated with an increased risk of thrombosis. Over the last decade, inherited thrombophilia is often referred as a possible cause of recurrent miscarriages and in vitro fertilisation (IVF) failure. However, many studies in this area still give conflicting results, so the goal of our study was to determine the effect of thrombophilia on pregnancy outcome and success of IVF. The study included 38 patients with proven gene mutation for thrombophilia and 53patients without mutations...

Recurrent pregnancy loss is considered when a female undergoes at least two consecutive, spontaneous abortions or more than two alternatively. This condition affects approximately 5% of women in reproductive age. Several causes of recurrent abortion have been established, but nevertheless, approximately half of all cases remain unexplained. Thrombophilic disorders have been suggested as a possible cause of recurrent miscarriage. A single 20210 G-A mutation of the 3'-untranslated region of (F2) has been reported as a cause of inherited thrombophilia...

Haemostatic and vascular biology mechanisms appear to play an important role in the pathogenesis of placenta-mediated pregnancy complications. Although low-dose aspirin (LDA) has a modest effect in preventing preeclampsia, antithrombotic interventions, LDA and low molecular weight heparin (LMWH) have not definitively proven their effectiveness in women with placenta-mediated pregnancy complications selected by previous pregnancy outcome alone. Given the heterogeneous aetiology of placenta-mediated pregnancy complications, it is critical to stratify patients according to maternal and fetal characteristics and disease mechanisms rather than simply by pregnancy outcome, such as miscarriage...

BACKGROUND: Recurrent miscarriage is a major women's health problem. Aspirin and heparin have been shown to have potentially beneficial effects on trophoblast implantation. However, few published data on this issue are available from developing countries. METHODS: An open clinical trial was conducted at the Department of Obstetrics and Gynecology at Misurata Teaching Hospital in Libya from January 2009 to December 2010 to investigate the effects of treatment with low dose aspirin (LDA) versus treatment with low-molecular-weight-heparin (LMWH) in combination with LDA on patients with a history of recurrent miscarriages...

Although Philadelphia-negative myeloproliferative neoplasms (MPNs) occur typically in middle to advanced age, any age group may be affected, posing a challenge for their management during pregnancy when they occur in young females. There is a high incidence of thromboembolic events and pregnancy complications in patients with myeloproliferative neoplasms, and a possible relationship between these complications is a matter of concern. The aim of this article was to correlate thrombosis and pregnancy outcome in 158 females with ET experiencing 237 pregnancies...

Pregnancy is a proinflammatory and hypercoagulable state. Miscarriage concerns approximately 15% of pregnancies. Recurrent miscarriage is a rather rare condition with an estimated incidence of 1% to 3%. However, despite years of investigation, the etiology is not established in up to 50% of cases. A multidisciplinary approach in the evaluation of miscarriage is essential to understand the cause and risk of recurrence. Although genetic factors are the major cause of spontaneous miscarriages, their relationship with recurrent miscarriage is less frequent...

BACKGROUND: Recurrent pregnancy loss is (RPL) a heterogeneous condition. While the role of acquired thrombophilia has been accepted as an etiology for RPL, the contribution of specific inherited thrombophilic gene polymorphisms to the disorder has been remained controversial. METHODS: One hundred women with a history of two or more consecutive abortions and 100 women with at least two live births and no miscarriages were included in the study and evaluated for the presence of 11 thrombophilic gene polymorphisms (Factor V LEIDEN, Factor V 4070 A/G, Factor V 5279 A/G, Factor XIII 103 G/T, Factor XIII 614 A/T, Factor XIII 1694 C/T, PAI-1 -675 4G/5G, ITGB3 1565 T/C, β-Fibrinogen -455G/A, MTHFR 677 C/T, MTHFR 1298 A/C) using PCR-RFLP technique...

BACKGROUND Poor fertility outcomes in women with recurrent implantation failure (≥ RIF) present significant challenges in assisted reproduction, and various adjuncts, including heparin, are used for potential improvement in pregnancy rates. We performed this systematic review and meta-analysis to evaluate the effect of low-molecular-weight heparin (LMWH) on live birth rates (LBRs) and implantation rates (IRs) in women with RIF and undergoing IVF. METHODS Studies comparing LMWH versus control/placebo in women with RIF were searched for on MEDLINE, EMBASE, Cochrane Library, conference proceedings and databases for registered and ongoing trials (1980-2012)...

BACKGROUND Although an association between thrombophilia and pregnancy loss has been observed in many studies, little is known about the pathophysiological mechanisms behind this association. Considering the association between thrombophilia and pregnancy loss, the efficacy of antithrombotic therapy for women with pregnancy loss (with or without thrombophilia) has been studied for the past 30 years. METHODS We performed a comprehensive review of the literature on the strength of the association between thrombophilia and pregnancy loss, the pathophysiological mechanisms and the efficacy of antithrombotic therapy to increase the chance of live birth...

Recent studies have associated pregnancy loss with subclinical hypothyroidism, defined as elevated thyroid-stimulating-hormone level, with normal free thyroxine. In overt hypothyroidism, the free thyroxine is low. Subclinical and overt hypothyroidism occurs in 0.25-2.5% and 0.2-0.3% of pregnancies respectively. We examined the prevalence of subclinical and undiagnosed overt hypothyroidism in women with recurrent miscarriage, late miscarriage and stillbirth attending the Pregnancy Loss Clinic. Data was collected from the Pregnancy Loss Clinic records...
