OBJECTIVE: To determine the proportion of couples affected by recurrent spontaneous abortion in which one partner carries balanced translocations among three chromosomes. METHODS: In a retrospective study, G-banded chromosome complements were analyzed for couples affected by recurrent spontaneous abortion who were referred to Niigata University Hospital, Japan, between January 1, 1990, and December 31, 2011. The frequency of couples in whom one of the partners carried balanced translocations among three chromosomes was determined, and the clinical outcomes for affected couples who subsequently achieved term pregnancies were reviewed...

The reported prevalence of antiphospholipid antibodies in women with a chief complaint of pregnancy loss varies, as does the risk of adverse outcomes in subsequent pregnancies. Our objectives were to assess the prevalence of antiphospholipid antibodies meeting revised Sapporo thresholds among women presenting with a chief complaint of pregnancy loss and risks in subsequent pregnancies for these women. We examined a retrospective cohort of patients presenting with a chief complaint of pregnancy loss between 2003 and 2012...

REVIEW
Yadava B Jeve, William Davies
Recurrent miscarriages are postimplantation failures in natural conception; they are also termed as habitual abortions or recurrent pregnancy losses. Recurrent pregnancy loss is disheartening to the couple and to the treating clinician. There has been a wide range of research from aetiology to management of recurrent pregnancy loss. It is one of the most debated topic among clinicians and academics. The ideal management is unanswered. This review is aimed to produce an evidence-based guidance on clinical management of recurrent miscarriage...

Placenta-mediated pregnancy complications, including preeclampsia, placental abruption, intrauterine growth restriction/small for gestational age and recurrent or late pregnancy loss, affect over 5% of pregnancies and can result in significant maternal and perinatal morbidity and mortality. These complications have been suggested to at least partly arise from placental insufficiency, possibly as a result of inappropriate coagulation activation. This association has led to the hypothesis that anticoagulant therapy, such as low molecular weight heparin, might reduce their occurrence...

BACKGROUND: Because immunological aberrations might be the cause of miscarriage in some women, several immunotherapies have been used to treat women with otherwise unexplained recurrent pregnancy loss. OBJECTIVES: The objective of this review was to assess the effects of any immunotherapy, including paternal leukocyte immunization and intravenous immunoglobulin on the live birth rate in women with previous unexplained recurrent miscarriages. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (11 February 2014) and reference lists of retrieved studies...

OBJECTIVE: To characterize the types of genetic abnormalities and their prevalence in early pregnancy loss at different developmental stages. We hypothesized that the prevalence of genetic abnormalities in pregnancy loss would differ across developmental stages. METHODS: Women with a pregnancy loss at < 20 weeks' gestation (n = 86) were enrolled at the time of diagnosis. Maternal tissue without a fetal component was found in 13 samples. Chromosomal microarray analysis (CMA) was performed on 74 samples (including two samples from a twin pregnancy); 15 were pre-embryonic (no visible embryo on ultrasound examination), 31 were embryonic (embryo; 6 + 0 to 9 + 6 weeks' gestation) and 28 were fetal (fetus; 10 + 0 to 19 + 6 weeks' gestation) losses...

There are few conditions in medicine associated with more heartache to patients than recurrent pregnancy loss (RPL). The management of early RPL is a formidable clinical challenge for physicians. Great strides have been made in characterizing the incidence and diversity of this heterogeneous disorder, and a definite cause of pregnancy loss can be established in more than half of couples after a thorough evaluation. In this review, current data are evaluated and a clear roadmap is provided for the evaluation and treatment of RPL...

Mid-trimester pregnancy loss (MTL) occurs between 12 and 24 weeks' gestation. The true incidence of this pregnancy complication is unknown, because research into MTL in isolation is scarce, although the estimated incidence has been noted to be 2% to 3% of pregnancies. A comprehensive preconceptual screening protocol is recommended, because the cause for an MTL may be present in isolation or combined (dual pathology), and is often heterogeneous. Patients with a history of MTL are at an increased risk of future miscarriage and preterm delivery...

Common endocrinopathies are a frequent contributor to spontaneous and recurrent miscarriage. Although the diagnostic criteria for luteal phase defect (LPD) is still controversial, treatment of patients with both recurrent pregnancy loss and LPD using progestogen in early pregnancy seems beneficial. For patients who are hypothyroid, thyroid hormone replacement therapy along with careful monitoring in the preconceptual and early pregnancy period is associated with improved outcome. Women with polycystic ovary syndrome (PCOS) have an increased risk of pregnancy loss...

Women with unexplained recurrent pregnancy loss (RPL) represent a highly heterogeneous group of patients. Past studies have investigated systemic endocrine and immunologic mechanisms as potential causes for pregnancy loss in unexplained RPL, while exciting new work has focused on spermatozoal, embryonic, and endometrial characteristics to explain the regulation of implantation and subsequent pregnancy loss. In the clinical and research context, stratification of women with unexplained RPL according to whether they have a high probability of pathologic status will help select women who are most appropriate for further investigation and potential future treatment...

OBJECTIVE: We sought to determine subsequent pregnancy outcomes in a cohort of women with a history of unexplained recurrent miscarriage (RM) who were not receiving medical treatment. STUDY DESIGN: This was a prospective cohort study, of women with a history of three unexplained consecutive first trimester losses, who were recruited and followed in their subsequent pregnancy. Control patients were healthy pregnant patients with no previous adverse perinatal outcome...

PURPOSE OF REVIEW: To review the recent diagnostic criteria, clinical implications, and therapeutic protocols for antiphospholipid antibody syndrome (APS). RECENT FINDINGS: Much has been learned in the recent years concerning the diagnosis of and clinical implications associated with the APS. A number of studies demonstrate some pathophysiologic mechanisms that suggest the impact of antiphospholipid antibodies (APAs) on successful growth and development of the placenta, and ultimately the embryo...

Recurrent miscarriage is defined as the loss of three consecutive pregnancies before 20 weeks' gestational age. Patients are referred to subspecialists such as reproductive endocrinology or maternal fetal medicine to exclude the most common causes of recurrent miscarriage including autoimmune disorders, structural uterine pathology, metabolic derangements, hematologic conditions, and chromosomal abnormalities. Unfortunately, this extensive list of conditions accounts for less than 50% of patients affected by recurrent miscarriage, leaving the remaining 50% without answers...

OBJECTIVE: To assess the impact of low molecular weight heparin (LMWH) treatment in 50 pregnancies of women with inherited thrombophilia and adverse pregnancy outcome (APO) in previous untreated pregnancies. The impact of "Conventional" (FVL, PT, AT, PC, PS) and "Novel" (MTHFR, PAI-1, ACE) thrombophilias on APO was investigated. METHODS: The primary outcomes (PO) were: early and late pregnancy loss (EPL, LPL), preterm birth (PTB) or term birth (TB) compared to the last untreated pregnancies of the same women...

The aim of this study was to investigate the association between polymorphisms in folic acid metabolism-related genes and idiopathic recurrent early pregnancy loss (REPL). A prospective case-control study was performed on a cohort of 82 REPL patients and 166 healthy controls. Genotyping of methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C was assessed by applying polymerase chain reaction for amplification followed by DNA sequencing, for methionine synthase reductase A66G, solute carrier family 19, member 1 (SLC19A1) G80A and C696T, and genotyping was done by utilizing the Sequenom MassARRAY system...

Recurrent pregnancy loss (RPL) is defined as the occurrence of two or more consecutive pregnancy losses. It is an important reproductive condition with a complex etiology. In approximately 50% of RPL cases an explanation for the cause is not found and they are therefore classified as idiopathic RPL. One of the causes implicated in RPL is thrombophilia, which consists of hemostatic disorders that lead to an increase in thromboembolic processes. The aim of this study was to evaluate polymorphic variants in genes related to thrombophilia as a risk factor in women with RPL...

INTRODUCTION Embryo implantation is a complex process involving maternal hormonal changes, immune responses and maturational events in the embryo. A pregnancy could fail when these events are not synchronized. It is speculated that in women, an elevation of natural killer (NK) cells may have an effect on reproductive performance, and NK cell levels in blood are currently being used as a diagnostic test to guide the initiation of therapies in patients with infertility. METHODS We conducted a systematic review to evaluate the (i) levels of NK cells in blood and endometrium in infertile versus fertile women, (ii) association between NK cells and IVF outcome, (iii) levels of NK cells in blood and endometrium in women with recurrent miscarriage (RM) versus controls...

BACKGROUND: Inherited thrombophilias have inconsistently been linked to adverse pregnancy outcomes. Differences in study design, size and population could explain this heterogeneity. OBJECTIVE: The aim of the present study was to evaluate if factor (F)V Leiden G1691A, prothrombin mutation G20210A (PTM) and methylenetetrahydrofolate reductase C677T (MTHFR) increased the risk of severe preeclampsia, fetal growth restriction, very preterm delivery, placental abruption and a composite of these outcomes also including stillbirth...
