BACKGROUND: The Congenital Human Cytomegalovirus Infection Prevention (CHIP) study, a randomized, blinded, placebo-controlled trial, demonstrated that the efficacy of hyperimmune globulin (HIG) was not different from that of placebo regarding transmission of cytomegalovirus (CMV) from mothers to newborns. Our aim was to analyze histologically HIG effects on placentas collected for the CHIP study. MATERIALS AND METHODS: Virological and histological analyses were performed on 40 placentas from transmitter and nontransmitter HIG-treated and untreated mothers by assessing the number of CMV-positive cells, tissue viral load, tissue damage, and compensatory mechanisms...

Congenital cytomegalovirus (CMV) infections represent one leading cause of neurodevelopmental disorders. Recently, we reported on a rat model of CMV infection of the developing brain in utero , characterized by early and prominent infection and alteration of microglia-the brain-resident mononuclear phagocytes. Besides their canonical function against pathogens, microglia are also pivotal to brain development. Here we show that CMV infection of the rat fetal brain recapitulated key postnatal phenotypes of human congenital CMV including increased mortality, sensorimotor impairment reminiscent of cerebral palsy, hearing defects, and epileptic seizures...

The success of prevention of mother to child transmission programs over the last two decades has led to an increasing number of infants who are exposed to human immunodeficiency virus (HIV), but who are not themselves infected (HIV-exposed, uninfected infants). Although the morbidity and mortality among HIV-exposed, uninfected infants is considerably lower than that among HIV-infected infants, they may remain at increased risk of infections in the first 2 years of life compared with their HIV-unexposed peers, especially in the absence of breastfeeding...

BACKGROUND: Congenital cytomegalovirus (CMV) infection (cCMV) is an important cause of hearing loss and cognitive impairment. Prior studies suggest that HIV-exposed children are at higher risk of acquiring cCMV. We assessed the presence, magnitude, and risk factors associated with cCMV among infants born to HIV-infected women, who were not receiving antiretrovirals during pregnancy. METHODS: cCMV and urinary CMV load were determined in a cohort of infants born to HIV-infected women not receiving antiretrovirals during pregnancy...

Congenital cytomegalovirus (CMV) infection is the most common infectious cause of sensorineural hearing loss in children. While the importance of CMV‑induced SNHL has been described, the mechanisms underlying its pathogenesis and the role of inflammatory responses remain elusive. The present study established an experimental model of hearing loss after systemic infection with murine CMV (MCMV) in newborn mice. Auditory brainstem responses were tested to evaluate hearing at 3 weeks, expression of inflammasome‑-associated factors was assessed by immunofluorescence, western blot analysis, reverse transcription‑quantitative polymerase chain reaction and ELISA...

Background: Infection with cytomegalovirus (CMV) during pregnancy may lead to congenital disease. Very little is known about the seroepidemiology of CMV infection in pregnant women in Mexico. We sought to determine the seroprevalence and correlates of CMV infection in pregnant women in Aguascalientes City, Mexico. Methods: Through a cross-sectional study design, 289 pregnant women were examined for anti-CMV IgG and IgM antibodies in Aguascalientes City, Mexico. A standardized questionnaire was used to obtain the socio-demographic, clinical and behavioral characteristics of the pregnant women...

Background: Newborns with congenital cytomegalovirus (CMV) infection are at high risk for developing permanent sequelae. Intravenous ganciclovir therapy is frequently used for the treatment of congenital CMV infection. Target area under the concentration versus time curve (AUC0-24 ) of 40-50 μg·h/mL is recommended. The standard dose resulted in a large variability in ganciclovir exposure in newborns, indicating the unmet need of dosage individualization in this vulnerable population, but the implementation of this strategy remains challenging in clinical practice...

Each year, thousands of children are born with or develop permanent disabilities such as hearing loss, vision loss, motor and cognitive deficits from congenital CMV infection (cCMV). However, awareness of cCMV and its associated sequelae is very low in pregnant women and healthcare providers. Both targeted and universal approaches to screen newborns for CMV infection are now achievable due to recent scientific advances including the development of a rapid, high-throughput method for detecting CMV in saliva, the efficacy of antiviral treatment in symptomatic infants, and the demonstration of cost effectiveness of CMV screening...

Congenital HCMV infection is a leading infectious cause of long-term neurodevelopmental sequelae. Infection of newborn mice with MCMV intraperitoneally is a well-established model of congenital HCMV infection, which best recapitulates the hematogenous route of virus spread to brain and subsequent pathology. Here we used this model to investigate the role, dynamics and phenotype of CD8+ T cells in the brain following infection of newborn mice. We show that CD8+ T cells infiltrate the brain and form a pool of tissue-resident memory T cells (TRM cells) that persist for lifetime...

BACKGROUND: Since there is no effective treatment or vaccine against the congenital cytomegalovirus (cCMV) infection, knowledge and awareness of medical doctor's (MDs) especially family doctors are essential for preventive strategies and it also seems to be usually ignored by healthcare providers. Aim of this study was to investigate awareness of MDs about cCMV infection in Iran. METHODS: A single page questionnaire was randomly distributed among 450 MDs including general practitioners, pediatricians, gynecologists, internal and other medical specialists concerning of their knowledge in clinical presentation, diagnosis, prevention, prognosis, epidemiology, transmission, and management of cCMV infection...

Background: Most congenital CMV infections in highly seropositive populations occur in infants born to women with preexisting CMV seroimmunity. Although essential for developing prevention strategies, CMV shedding patterns in pregnant women with non-primary infections have not been characterized. We investigated correlates of CMV shedding in a cohort of seropositive pregnant women. Methods: In a prospective study, saliva, urine, vaginal swabs, and blood were collected from 120 CMV seropositive women in the 1st, 2nd, and 3rd trimesters and one month postpartum...

Congenital Cytomegalovirus infection (cCMV) is the most common cause of congenital infections worldwide causing permanent long-term impairment (LTI). cCMV immunopathogenesis remains largely unknown due to the complex interplay between viral, maternal, placental and child factors. The aim of this study was to determine the possible role of particular HLA antigens, of the number of HLA mismatches (mm) and non-inherited maternal antigens (NIMAs) in a large retrospective nation-wide cohort of children with cCMV and their mothers...

The Newborn Hearing Screening Programme (NHSP) was established in Cork University Maternity Hospital (CUMH) in April 2011. Between April 2011 and July 2014, 42 infants were identified with a Permanent Childhood Hearing Impairment (PCHI). Following this diagnosis, infants underwent a paediatric assessment according to recognised guidelines with the intention of identifying the underlying aetiology of the PCHI. The aim of this study was to assess the findings of this aetiological workup via retrospective chart review...

Cytomegalovirus (CMV) is the most common cause of congenital infections in humans occurring in 1% of all liveborns. Symptomatic congenital CMV infection involves multiple systems and causes significant morbidity and mortality in newborns. Isolated CMV infection of the kidneys in a living infant has not been reported in literature. Here, we report an infant who presented only with renomegaly and renal biopsy showed extensive CMV inclusions. Serum and urine polymerase chain reaction for CMV were positive, and CMV involvement of other organs was ruled out...

A cytomegalovirus (CMV) vaccine that is effective at preventing congenital infection and reducing CMV disease in transplant patients remains a high priority as no approved vaccines exist. While the precise correlates of protection are unknown, neutralizing antibodies and antigen-specific T cells have been implicated in controlling infection. We demonstrate that the immunization of mice and nonhuman primates (NHPs) with lipid nanoparticles (LNP) encapsulating modified mRNA encoding CMV glycoproteins gB and pentameric complex (PC) elicit potent and durable neutralizing antibody titers...
