We report a full-term neonate presenting with symptomatic congenital cytomegalovirus (CMV) infection with hepatosplenomegaly, 'blueberry muffin' rash, intracranial calcifications, thrombocytopenia and respiratory distress. Maternal history was relevant for Guillain-Barré syndrome (GBS) during the first trimester of pregnancy. CMV infection is an important cause of GBS; thus, women presenting GBS during pregnancy should be screened for CMV infection. If positive, they may benefit from specialised monitoring and treatment in the antenatal period, which may decrease the risk of major neurodevelopmental sequelae of congenital CMV in the neonate...

Gastroschisis risk is highest in offspring of young women and is increasing in prevalence, suggesting that exposures that are increasingly common among younger females may be causal. Some infections by viruses in the herpes family are more common in the earlier childbearing years and have been increasing in prevalence over time. Data from the Finnish Maternity Cohort were linked to Finnish malformation and birth registers (1987-2012) for this study, a nested case-control study of mothers of offspring with gastroschisis and age-matched controls...

Cell transfer between mother and fetus were demonstrated previously in several species which possess haemochorial placenta (e.g. in humans, mice, rats, etc.). Here we report the assessment of fetal and maternal microchimerism in non-transgenic (non-TG) New Zealand white rabbits which were pregnant with transgenic (TG) fetuses and in non-TG newborns of TG does. The TG construct, including the Venus fluorophore cDNA driven by a ubiquitous cytomegalovirus enhancer, chicken ß-actin promoter (CAGGS), was previously integrated into the rabbit genome by Sleeping Beauty transposon system...

Congenital human cytomegalovirus (HCMV) infection occurs in ~0.64% of infants born each year in the United States and is the leading nongenetic cause of childhood neurodevelopmental disabilities. No licensed HCMV vaccine is currently available. Natural immunity to HCMV in women before pregnancy is associated with a reduced risk of fetal infection, suggesting that a vaccine is feasible if it can reproduce immune responses elicited by natural infection. On the basis of this premise, we developed a whole-virus vaccine candidate from the live attenuated AD169 strain, with genetic modifications to improve its immunogenicity and attenuation...

Congenital cytomegalovirus (CMV) infection causes severe disabilities and developmental delays. Women's awareness of CMV is low. Only about half of healthcare providers report counseling women about behaviors to reduce CMV risk and public health education is limited. Routine CMV counseling is not recommend. Providers may lack time to counsel women; other conditions may take priority for counseling; there may be a perception that women are reluctant to follow advice. This cross-sectional descriptive study examined women's attitudes toward CMV prevention behaviors...

Background: Staff in children's hospitals may run an increased risk of cytomegalovirus (CMV) contact infection leading to a congenital CMV fetopathy during pregnancy. The main risk factor is close contact with inapparent carriers of CMV among infants (<3 years). We therefore examined CMV seroprevalence (SP) and possible risk factors for CMV infection among staff at a children's hospital. Method: In 2014, staff at a metropolitan children's hospital were offered a CMV antibody test in the context of occupational health screening...

Human leukocyte antigen-G (HLA-G) is a nonclassical HLA class I antigen that is expressed during pregnancy contributing to maternal-fetal tolerance. HLA-G can be expressed as membrane-bound and soluble forms. HLA-G expression increases strongly during viral infections such as congenital human cytomegalovirus (HCMV) infections, with functional consequences in immunoregulation. In this work we investigated the expression of soluble (s)HLA-G and beta-2 microglobulin (component of HLA) molecules in correlation with the risk of transmission and severity of congenital HCMV infection...

Most published cases of cytomegalovirus infection in pregnancy relate to congenital abnormalities in neonates infected in early pregnancy, while the mother remains asymptomatic. We describe a diagnostically challenging case of an immunosuppressed woman with scleroderma who developed deranged liver function tests attributed to intrahepatic cholestasis of pregnancy and haemolysis, elevated liver enzymes and low platelets syndrome but was ultimately found to have disseminated cytomegalovirus. Cytomegalovirus can present in a myriad of ways...

The recent association between Zika virus (ZIKV) infection during pregnancy and fetal microcephaly has led to a renewed interest in the mechanisms by which vertically transmitted microorganisms reach the fetus and cause congenital disease. In this Opinion article, we provide an overview of the structure and cellular composition of the human placenta and of the mechanisms by which traditional 'TORCH' pathogens (Toxoplasma gondii, other, rubella virus, cytomegalovirus and herpes simplex virus) access the fetal compartment...

REVIEW
Bodo Plachter
Congenital human cytomegalovirus (HCMV) infection is one leading cause of childhood disabilities. Prevention of congenital HCMV disease by vaccination has consequently been identified as a priority public healthcare goal. Several vaccine candidates have been introduced in the past that aimed at the prevention of primary HCMV infection in pregnancy. None of these has provided complete protection, and no licensed vaccine is thus far available. An additional level of complexity has been reached by recent studies indicating that the burden of HCMV transmission and disease following non-primary infections in pregnancy may be higher than previously anticipated...

The goal of this work was the evaluation of the frequency of human CMV infection among the women, whose pregnancy ended in miscarriage, detection of active forms of infection and treatment before pregnancy. Virological and sero-immunological techniques were used. A total of 116 women who had miscarriages before the 28 week of pregnancy were submitted to the CMV test. 109 women (94.0%) demonstrated positive results. 49 women (42.2%) had active form of the cytomegalovirus infection. 13 women (26.5%) had the recurrent form and 36 patients (73...

Cytomegalovirus (CMV) is the most common congenital viral infection. Mother-to-child transmission can cause severe child disability. Intact CMV-specific cell-mediated immunity (CMI) was shown to prevent uncontrolled replication in healthy individuals. This study aimed to determine whether CMV-specific CMI is impaired in pregnant women, thus potentially increasing the overall risk for active CMV replication and transmission. CMV-specific CMI in peripheral blood of 60 pregnant women was determined using T-Track® CMV for detection of IE-1 and pp65-reactive effector cells by IFN-γ ELISpot, and compared to the CMV-IgG and -IgM serostatus...
