Human cytomegalovirus is a significant agent of hepatic involvement in neonates. In this study, we investigated the polymorphisms and features of the viral genes UL144 and UL146 as well as their significance to congenital hepatic involvement. In 79 neonates with congenital cytomegalovirus infection and hepatic involvement, full length UL144 and UL146 were successfully amplified in 73.42% and 60.76% of cases, respectively. Sequencing indicated that both genes were hypervariable. Notably, UL144 genotype B was highly associated with aspartate aminotransferase (P = 0...

Cytomegalovirus (CMV) infection remains the leading cause of congenital virus infection in developed countries. Measuring the national prevalence of this infection, especially among women of childbearing age, is of great value to estimate the risk of congenital CMV infection, as well as to identify risk groups that should be targeted for behavioural interventions and/or vaccination once a CMV vaccine finally becomes available. In order to fulfil these objectives, a seroprevalence survey was conducted in 2010, using a nationally representative, population-based sample of 2536 people aged between 15 and 49 years, living in metropolitan France and attending private microbiological laboratories for blood testing...

Congenital cytomegalovirus (CMV) infection is the leading viral cause of birth defects and developmental disabilities in developed countries. However, CMV seroprevalence and burden of congenital CMV infection are not well defined in China.Cohort of newborns from 5 birthing hospitals in 2 counties of Shandong Province, China, were enrolled from March 2011 to August 2013. Dried blood spots (DBS) and saliva were collected within 4 days after birth for IgG testing for maternal seroprevalence and real-time PCR testing for congenital CMV infection, respectively...

Zika virus is an emerging mosquito-borne (Aedes genus) arbovirus of the Flaviviridae family. Following epidemics in Micronesia and French Polynesia during the past decade, more recent Zika virus infection outbreaks were first reported in South America as early as May 2013 and spread to now 50 countries throughout the Americas. Although no other flavivirus has previously been known to cause major fetal malformations following perinatal infection, reports of a causal link between Zika virus and microcephaly, brain and ocular malformations, and fetal loss emerged from hard-hit regions of Brazil by October 2015...

: Congenital human cytomegalovirus (HCMV) infection is a significant cause of abnormal neurodevelopment and long term neurological sequelae in infants and children. Resident cell populations of the developing brain have been suggested to be more susceptible to virus-induced cytopathology, a pathway thought to contribute to the clinical outcomes following intrauterine HCMV infection. However, recent findings in a newborn mouse model of this infection in the developing brain have indicated that elevated levels of proinflammatory mediators leading to mononuclear cell activation and recruitment could underlie the abnormal neurodevelopment...

BACKGROUND AND OBJECTIVES: Cytomegalovirus (CMV) is the most common congenital infection and nongenetic cause of congenital sensorineural hearing loss in the United States. Utah was the first state to pass legislation mandating CMV screening for newborns who fail newborn hearing screening (NBHS). The study objective was to present outcomes of hearing-targeted CMV screening and determine factors predicting CMV screening. METHODS: We used Utah Department of Health HiTrack and Vital Records databases to examine CMV screening from 509 infants who failed NBHS in the 24 months after implementation of the Utah legislation...

BACKGROUND: Both primary and non-primary maternal cytomegalovirus (CMV) infection during pregnancy can lead to vertical transmission. We evaluated the proportion of maternal primary/non-primary infections among 26 babies with symptomatic congenital CMV infection born in Finland from 2000 to 2012. METHODS: We executed a database search on hospital records from all five university hospitals in Finland to identify infants with congenital CMV infection. The preserved maternal serum samples drawn at the end of the first trimester were analysed for CMV antibodies...

: Human cytomegalovirus (HCMV) is the leading cause of congenital viral infection and developing a prophylactic vaccine is of high priority to public health. We recently reported a replication-defective human cytomegalovirus with restored pentameric complex gH/gL/pUL128-131 for prevention of congenital HCMV infection. While the quantity of vaccine-induced antibody responses can be measured in a viral neutralization assay, assessing the quality of such responses, including the ability of vaccine-induced antibodies to cross neutralize the field strains of HCMV, remains a challenge...

In humans, the herpes virus family member cytomegalovirus (CMV) is the most prevalent mediator of intrauterine infection-induced congenital defect. Central nervous system (CNS) dysfunction is a distinguishing symptom of CMV infection, and characterized by ventriculoencephalitis and microglial nodular encephalitis. Reports on the initial distribution of CMV particles and its receptors on the blood brain barrier (BBB) are rare. Nevertheless, several factors are suggested to affect CMV etiology. Viral particle size is the primary factor in determining the pattern of CNS infections, followed by the expression of integrin β1 in endothelial cells, pericytes, meninges, choroid plexus, and neural stem progenitor cells (NSPCs), which are the primary targets of CMV infection...

BACKGROUND: Scarce data exist about screening, diagnosis and prognosis of non-primary Cytomegalovirus (CMV) during pregnancy. We aimed to examine antenatal diagnosis of maternal non-primary CMV infection and to identify risk factors for congenial CMV disease. METHODS: Retrospective cohort of 107 neonates with congenital symptomatic CMV infection, following either primary (n = 95) or non-primary (n = 12) maternal CMV infection. We compared the groups for the manifestations and severity of congenial CMV disease, as well as for possible factors associated with the risk of developing CMV related infant morbidity...

BACKGROUND AND OBJECTIVE: Congenital cytomegalovirus (cCMV) infection remains a leading cause of childhood hearing loss. Currently universal CMV screening at birth does not exist in the United States. An alternative approach could be testing infants who do not pass their newborn hearing screening (NHS) for cCMV. This study was undertaken to evaluate whether a targeted approach will identify infants with CMV-related sensorineural hearing loss (SNHL). METHODS: Infants born at 7 US medical centers received NHS and were also screened for cCMV while in the newborn nursery...

BACKGROUND: The immunoglobulin (Ig) G avidity index (AI) is useful to detect primary cytomegalovirus (CMV) infection. However, because IgG matures with time, this index is not useful to detect a primary infection, unless measured at an appropriate time. OBJECTIVES: We aimed to clarify the difference between using IgG AI and IgM positivity according to the stage of pregnancy to identify congenital CMV infection risk. STUDY DESIGN: We collected the serum samples from 1115 pregnant women who underwent maternal screening for primary infection (n = 956) and were referred to our hospital because of CMV IgM positivity (n = 155) or had abnormal fetal ultrasonography findings (n = 4)...

BACKGROUND: Congenital cytomegalovirus infection (cCMV) is a leading non-genetic cause of permanent congenital or early-onset hearing loss (PCEHL). Although cCMV rates are high despite near-universal seroimmunity, the contribution of cCMV to PCEHL in the developing world is unclear. METHODS: Neonates at a rural north Indian hospital were screened for cCMV by saliva PCR and hearing by distortion product otoacoustic emission (DPOAE) testing. CMV positive infants and those not passing newborn hearing screening (NHS) were evaluated by auditory brainstem response to confirm PCEHL...

Congenital CMV-infection (cCMV) represents a relevant cause of deafness and neurological damage in newborns. Intrauterine CMV transmission might result after primary or non-primary infections, though at different rates (30% vs 0.2%, respectively). At present prenatal diagnosis of CMV infection is mainly based on maternal serology, detection of CMV-DNA in amniotic fluid and fetal blood, and US and MRI imaging. Recent evidences suggest that cCMV may be an immune-mediated disease and that evaluation of humoral and especially T-cell immunity may improve the overall prenatal diagnosis...

Cytomegalovirus (CMV) is the most common cause of congenital viral infection, affecting 0.2 to 2.3% of all live births in developed countries. Very low birth weight and extremely low birth weight newborns are at higher risk of symptomatic CMV infection, most commonly secondary and acquired through breast milk. Gastrointestinal involvement is rare in acquired CMV infections, but it could be an important manifestation of postnatal infection in preterm infants admitted to neonatal intensive care units. Early onset of CMV gastrointestinal signs/symptoms is very rare...

Neonatal serum detection of cytomegalovirus (CMV) immunoglobulin M (IgM) has low sensitivity in identifying congenital cytomegalovirus (cCMV). Several reports have endeavored to associate the presence/absence of IgM to disease severity. Data were collected for all infants with cCMV followed in our clinic. Infant outcome after birth was compared between infants who tested positive or negative. Sensitivity of positive IgM in diagnosing cCMV was 40.7%. The rate of symptomatic disease in those who tested positive was statistically higher (67...
