NMOSD develops primarily in women of childbearing age, and several previous studies have shown that the disorder may increase the risk of miscarriage. However, there are no reports, to our knowledge, of fetal malformation, other than neonatal hydrocephalus, related to NMOSD. We report a 30-year-old woman who experienced recurrent neuritis and who was seropositive for AQP4-IgG. She became pregnant, and the fetus was found to have ectrodactyly. Histological analysis of the placenta showed moderate inflammatory infiltration; however, whether fetal malformation in NMOSD is related to inflammation and AQP4-IgG remains to be determined...

OBJECTIVES: To analyze the consequences of genital herpes infections in pregnant women. METHODS: The PubMed database and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS: The symptomatology of herpes genital rash is often atypical (NP2) and not different during pregnancy (Professional consensus). It is most often due to HSV2 (NP2). Seventy percent of pregnant patients have a history of infection with Herpes simplex virus, without reference to genital or labial localization, and this is in most cases type 1 (NP2)...

Chronic intervillositis is a rare condition, which is associated with severe obstetrical outcome and high recurrence rate. Obstetrical adverse events are intrauterine growth restriction, recurrent early miscarriages, intrauterine deaths and prematurity by placental insufficiency. The determination of the extension and the intensity of the chronic intervillositis are not currently standardized. High rates of recurrence have been described, but actually there is no reliable predictive biomarker. No treatment is currently validated, but the use of immunomodulatory drugs could be justified by the possible autoimmune or allo-immune origin...

Aspirin (acetylsalicylic acid) has been used ever since the Antiquity for its painkilling and anti-inflammatory effects. Its antiplatelet properties have then extended its indications to the field of coronaropathy and vascular cerebral disease, and finally to vascular placental disease. Aspirin has been widely prescribed since the 1980's to prevent pre-eclampsia, intra-uterine growth retardation and fetal death of vascular origin. It has also been proposed to prevent unexplained recurrent miscarriages. Its use during pregnancy is considered as safe, provided the daily doses do not exceed 100mg...

The balance between coagulation and fibrinolysis is an essential part in early pregnancy. Mutations in methylenetetrahydrofolate reductase (MTHFR) gene lead to decreased activity of the enzyme and hyperhomocysteinemia, which then induces platelet aggregation by promoting endothelial oxidative damage, possibly resulting in adverse effect on maintenance of pregnancy. We investigated the role of MTHFR single nucleotide polymorphisms (SNPs), C677T and A1298C, in Korean patients with recurrent pregnancy loss (RPL)...

OBJECTIVE: Antiphospholipid syndrome (APS) is a systemic autoimmune disorder of young adults associated with devastating pregnancy complications (recurrent miscarriages, preeclampsia and low birth weight) and vascular complications including thrombosis. The key components implicated in pathogenesis of APS are the complement cascade and tissue factor (TF) activity causing inflammation and coagulation. Purinergic signalling involving catabolism of ATP to adenosine by cell-surface enzymes CD39 and CD73 has anti-inflammatory and anti-thrombotic effects...

OBJECTIVES: A history of recurrent miscarriage is associated with future cardiovascular disease. The aim of this study was to determine novel cardiovascular biomarkers in women with a history of recurrent miscarriage as this might lead to a better understanding of the association. STUDY DESIGN: Women who visited the recurrent miscarriage clinic at Leiden University Medical Centre (between 2000 and 2010), and had three consecutive miscarriages ≤30 years were invited to participate in this follow-up study (between 2012 and 2014)...

Housekeeping genes (HKG) are presumed to be constitutively expressed throughout tissue types but recent studies have shown they vary with pathophysiology. Often, validation of appropriate HKG is not made. There is no consensus on which HKGs are most stably expressed in endometrial tissue so this study aimed to identify the most stable HKG in the endometrium of women with recurrent implantation failure (RIF) and recurrent miscarriages (RM). Inclusion criteria were women between 25-45 years (n = 45) suffering recurrent miscarriage (RM), recurrent implantation failure (RIF) or fertile controls...

Recurrent pregnancy loss is a physical and mental burden for women.  In Vietnam, exploring the cause of miscarriages is still a challenge to clinical physicians. We aimed to investigate the etiology of recurrent pregnancy loss in a national hospital of obstetrics and gynecology in Vietnam from 2012 to 2014. The cross-sectional study included 301 pregnant women with a history of recurrent pregnancy loss. The patients were examined and offered medical testing to determine cause(s). Based on testing we determined causation for (11...

Thyroid autoimmunity (TAI) appears to play a crucial role in female infertility, recurrent pregnancy loss and IVF failure. Thyroid autoantibodies against thyroid peroxidase and thyroglobulin have been shown to represent an independent risk factor for infertility and miscarriage. Moreover, thyroxin hormone administration reduces the risk of obstetrical complications in TAI positive women. The aim of our present study was to investigate the immunological background of female infertility and recurrent pregnancy loss in euthyroid and subclinical hypothyroid women with TAI focusing on innate immunity...

Up to 50% of recurrent miscarriage cases in women occur without an underlying etiology. In the current prospective case-control study, we determined the impact of CGG trinucleotide expansions of the FMR1 gene in 49 women with unexplained recurrent miscarriages. Case group consisted of women with 2 or more unexplained consecutive miscarriages. Blood samples were obtained and checked for the presence of expanded alleles of the FMR1 gene using polymerase chain reaction. Patients harboring the expanded allele, with a threshold set to 40 repeats, were further evaluated by sequencing...

BACKGROUND: There is evidence that NK-cell reactivity might affect graft outcome in transplant recipients and pregnancy in women. METHOD: NK-cell subsets were determined in whole blood using eight-colour-fluorescence flow cytometry in patients before and after renal transplantation, patients with recurrent miscarriage (RM) and healthy controls (HC). RESULTS: Patients late post-transplant (late-Tx) with functioning renal transplants showed abnormally low CD56dimCD16+ NK-cells containing both perforin and granzyme (vs HC p = 0...

PURPOSE: Recurrent pregnancy losses (RPL) are considered a pathological condition associated with heterogeneous laboratory and clinical findings, and are also linked to subfertility. We attempt to rank parameters derived from past history and diagnostic results with regard to the prognosis. METHODS: Observational trial on 719 consecutive couples who were referred to a tertiary immunological care centre (2006-2014) after three or more primary miscarriages. Information on past obstetric history and diagnostic procedures at baseline were correlated with cumulative pregnancy and delivery rates using Kaplan-Meier estimation, logistic regression and multivariate analysis...

INTRODUCTION: Generaly, natural killer cells (NK cells) are among the most important cells of our immune defense system. They are present in the blood, decidua but also in secretory endometrium. OBJECTIVE: We investigate an association between high density of NK cells CD56+ and NK cells CD16+ into blood and secretory endometrium in patients with up to now unexplained recurrent miscarriage. At the same time, we focused on diagnosis of antiphospholipid syndrome, congenital trombophilic factors, stress factor, and lenght of hormonal contraception before conception...

BACKGROUND: Approximately half of recurrent miscarriages have unexplained etiology. Recent evidences suggest that cytokines are important determinants in pregnancy maintenance and as such, cytokine gene polymorphisms, which can affect cytokine production and/or functionality, could play a role in the disorder. Thus, we aimed to investigate the association of selected cytokine gene polymorphisms with risk of recurrent miscarriage among Chinese. METHODS: TNF -238G > A, TNF -308G > A, IL1B -511 T > C, IL1B 3954C > T, IL6 -174G > C, IL6 -634C > G, IL10 -1082A > G and IFNG 874A > T polymorphisms were genotyped on 775 women with idiopathic recurrent miscarriage and 805 healthy parous control women...
