OBJECTIVE: Toxoplasmosis, cytomegalovirus (CMV), and Zika virus (ZIKV) are among the common infectious agents that may infect the fetuses vertically. Clinical presentations of these congenital infections overlap significantly, and it is usually impossible to determine the causative agent clinically. The objective was the comparison of neuroimaging findings in three fetuses who underwent intrauterine infection by toxoplasmosis, CMV, and ZIKV. METHODS: Three confirmed cases of congenital toxoplasmosis, CMV, and ZIKV infections were included in the study over 7 months prospectively...

Congenital human cytomegalovirus (HCMV) infection is the leading cause of neurological disabilities in children worldwide, but the mechanisms underlying these disorders are far from well-defined. HCMV infection has been shown to dysregulate the Notch signaling pathway in human neural progenitor cells (NPCs). As an important downstream effector of Notch signaling, the transcriptional regulator Hairy and Enhancer of Split 1 (Hes1) is essential for governing NPC fate and fetal brain development. In the present study, we report that HCMV infection downregulates Hes1 protein levels in infected NPCs...

Fifteen to 50% of fetal deaths remain unexplained after post-mortem examination depending on inclusion criteria and classification systems. Our aim was to examine a selection of unexplained fetal deaths in order to investigate whether any common chromosome aberrations or viral infections were present. Reports from 351 fetal autopsies performed at the Department of Pathology and Medical Genetics at St. Olavs University Hospital from 2001 through 2010 were reviewed. Of these, 105 fetal deaths were classified as unexplained...

Congenital cytomegalovirus (CMV) infection is the leading cause for sensorineural hearing loss and mental retardation in children without genetic diseases worldwide. There is little evidence guiding therapeutic strategies during pregnancy when intrauterine fetal CMV infection is confirmed. We provide a systematic review of the use of ganciclovir (GCV) or VGCV during pregnancy discussing safety of its use for mother and fetus and describe two cases of intrauterine therapy of fetal CMV infection with valganciclovir (VGCV)...

PURPOSE: To assess the knowledge, practice and attitudes of maternity clinicians regarding congenital cytomegalovirus (CMV). It is the most common congenital infection, and well-recognized cause of neurodevelopmental disability and hearing loss. New consensus recommendations state all pregnant women and health-care providers should be educated about congenital CMV infection and preventive measures. MATERIALS AND METHODS: An email questionnaire was distributed in October 2015 to specialists, diplomates (general practitioners), and trainees of the Royal Australian New Zealand College of Obstetricians and Gynaecologists (RANZCOG), and Victorian and New South Wales midwives...

Human cytomegalovirus (HCMV) is the most common congenital infection and a known cause of microcephaly, sensorineural hearing loss, and cognitive impairment among newborns worldwide. Natural maternal HCMV immunity reduces the incidence of congenital infection, but does not prevent the disease altogether. We employed a nonhuman primate model of congenital CMV infection to investigate the ability of preexisting antibodies to protect against placental CMV transmission in the setting of primary maternal infection and subsequent viremia, which is required for placental virus exposure...

Cytomegalovirus (CMV) is the most frequent congenital virus infection worldwide. The risk of congenital CMV (cCMV) transmission is highest in seronegative women who acquire primary CMV infection during pregnancy. A growing body of evidence indicates that secondary CMV infections in pregnant women with preconceptual immunity (either through reactivation of latent virus or re-infection with a new strain of CMV) contribute to a much greater proportion of symptomatic cCMV than was previously thought. Here, we describe a case of symptomatic cCMV infection in the newborn of a woman with proven immunity prior to pregnancy...

Cytomegalovirus (CMV) is the most common infectious cause of brain defects and neurological dysfunction in developing human babies. Due to the teratogenicity and toxicity of available CMV antiviral agents, treatment options during early development are markedly limited. Valnoctamide (VCD), a neuroactive mood stabilizer with no known teratogenic activity, was recently demonstrated to have anti-CMV potential. However, it is not known whether this can be translated into an efficacious therapeutic effect to improve CMV-induced adverse neurological outcomes...

OBJECTIVE: Our aim is to assess the neurodevelopmental outcome of children with a prenatal diagnosis of apparently isolated severe ventriculomegaly (SVM). METHOD: This is a retrospective cohort study from 1994 to 2011. We included fetuses with unilateral or bilateral ventriculomegaly equal to or greater than 15 mm at prenatal ultrasound and confirmed by magnetic resonance imaging, whose parents chose continuation of pregnancy past 22 weeks, and with no associated findings at diagnosis (i...

BACKGROUND: Fetal ventriculomegaly (VM) is defined as lateral ventricles measured above 10 mm. Some authors believe VM <12 mm are variants of the norm and need not be addressed for referral ultrasound. METHODS: A retrospective continuous cohort study of 127 confirmed fetal VM was divided into three groups after initial referral sonographic assessment: isolated VM <12 mm (group A), isolated VM ≥12 mm (group B), and VM associated with other malformations (group C)...

Congenital toxoplasmosis (CT) and cytomegalovirus infection (cCMV) may cause significant morbidity and even fetal or neonatal mortality. We aimed to quantify the disease burden of CT and cCMV in Belgium in terms of disability-adjusted life years (DALYs) and identify data gaps. The public health impact of CT and cCMV in Belgium in 2013 was 188 (95% uncertainty interval [UI], 43-419) and 1976 (95% UI, 757-4067) DALYs, respectively. The major data gaps identified were representative Belgian studies; information on important sequelae, intrauterine mortality, and termination of pregnancy; and late onset sequelae...

To assess the incidence, diagnosis, pathogenesis, and clinical and placental associations of congenital cytomegalovirus infection, 34 cases thereof diagnosed by placental/fetal or neonatal workup (group 1), and 494 placentas with villitis of unknown etiology (group 2) were extracted from a 6083-case placental database. 28 clinical and 47 placental phenotypes were compared between the two groups by Yates 2 or ANOVA using the Bonferroni correction. 26 group 1 cases did and 8 did not feature placental villitis, but all cases were positive as shown by immunohistochemistry and/or in situ hybridization...

Ample evidence exists for the presence of infectious agents at the maternal-fetal interface, often with grave outcomes to the developing fetus (i.e., Zika virus, brucella, cytomegalovirus, and toxoplasma). While less studied, pregnancy-related transmissible spongiform encephalopathies (TSEs) have been implicated in several species, including humans. Our previous work has shown that prions can be transferred from mother to offspring, resulting in the development of clinical TSE disease in offspring born to muntjac dams infected with chronic wasting disease (CWD) (1)...

Fetal hepatic calcifications can be caused by infections, chromosomal disorders, thrombotic events, ischemic hepatic necrosis and subcapsular hematomas among others events. Its features and clinical significance are still not well known. We performed an observational study to describe fetal hepatic calcifications and its association with main clinical and histopathological findings from the fetal autopsy database, between 2007 and 2014. Raw odds ratio analysis was performed. We reviewed 591 fetal autopsies: 14 cases with hepatic calcifications, 102 fetuses with chromosomal disorders; 13 with diagnosis of TORSCH (toxoplasma, rubella, syphilis, cytomegalovirus, herpes virus 1 and 2, and others) and 207 with any abnormality in the umbilical cord (UC)...

BACKGROUND AND PURPOSE: Cytomegalovirus is the leading intrauterine infection. Fetal MR imaging is an accepted tool for fetal brain evaluation, yet it still lacks the ability to accurately predict the extent of the neurodevelopmental impairment, especially in fetal MR imaging scans with unremarkable findings. Our hypothesis was that intrauterine cytomegalovirus infection causes diffusional changes in fetal brains and that those changes may correlate with the severity of neurodevelopmental deficiencies...

INTRODUCTION: We have previously shown that miRNAs produced from the Chromosome 19 MiRNA Cluster (C19MC), which are expressed almost exclusively in primate trophoblasts and are released into the maternal circulation, reduce viral replication in non-placental cells and can modulate migratory behavior of extravillous trophoblast. We sought to define the expression pattern of C19MC miRNA in early pregnancy and in response to viral infection in vitro and in vivo. METHODS: We prospectively followed women undergoing in vitro fertilization (IVF) and determined their blood level of C19MC miRNA using RT-qPCR...

Human cytomegalovirus (HCMV) infection is a leading cause of birth defects, primarily affecting the central nervous system and causing its maldevelopment. As the essential downstream effector of Notch signaling pathway, Hes1, and its dynamic expression, plays an essential role on maintaining neural progenitor /stem cells (NPCs) cell fate and fetal brain development. In the present study, we reported the first observation of Hes1 oscillatory expression in human NPCs, with an approximately 1.5 hour periodicity and a Hes1 protein half-life of about 17 (17...

The interaction of inhibitory killer cell Ig-like receptors (KIRs) with human leukocyte antigen (HLA) class I molecules has been characterized in detail. By contrast, activating members of the KIR family, although closely related to inhibitory KIRs, appear to interact weakly, if at all, with HLA class I. KIR2DS1 is the best studied activating KIR and it interacts with C2 group HLA-C (C2-HLA-C) in some assays, but not as strongly as KIR2DL1. We used a mouse 2B4 cell reporter system, which carries NFAT-green fluorescent protein with KIR2DS1 and a modified DAP12 adaptor protein...
