BACKGROUND: Maternal cytomegalovirus (CMV) and Rubella infections result in adverse neonatal outcomes. Both CMV and Rubella are more widespread in developing countries and in communities with lower socioeconomic status. Thus, the aim of this study was to determine IgM specific to CMV and Rubella among newborns and Maternal CMV-seroprevalence and to identify risk factors. METHOD AND FINDING: Using cross sectional study design a total of 312 (156 newborns and 156 mothers) study participants were recruited by simple random sampling technique from gynecology outpatient department (OPD) and ward, starting from April 1, 2015 to June 30, 2015...

Importance: Congenital cytomegalovirus (cCMV) infection is a major cause of childhood deafness. Most cCMV infections are not diagnosed without newborn screening, resulting in missed opportunities for directed care. Objective: To estimate the cost-effectiveness of universal and targeted newborn cCMV screening programs compared with no cCMV screening. Design, Setting, and Participants: Models were constructed using rates and outcomes from prospective cohort studies of newborn cCMV screening in US postpartum care and early hearing programs...

Viral infections in the fetus or newborn often involve the central nervous system (CNS) and can lead to significant morbidity and mortality. Substantial progress has been made in identifying interventions decreasing adverse neurodevelopmental outcomes in this population. This review highlights progress in treatment of important viruses affecting the CNS in these susceptible hosts, focusing on herpes simplex (HSV), cytomegalovirus (CMV), human immunodeficiency virus (HIV), and enteroviruses. The observation that high-dose acyclovir improves mortality in neonatal HSV disease culminated decades of antiviral research for this disease...

A male newborn developed a post-natal cytomegalovirus (CMV) infection, arising in the clinical setting of congenital thrombocytopenia, which was diagnosed as being alloimmune. The evidence of active CMV infection in an infant showing slow-resolution lower airways infection, persistent neonatal and low platelet volume thrombocytopenia, and diffuse eczema (associated to very high levels of serum immunoglobulin E) led to the diagnosis of Wiskott-Aldrich syndrome (WAS) before the third month of life, despite the presence of several confounding clinical factors...

Human cytomegalovirus (HCMV) is the leading viral cause of birth defects, including microcephaly, neurological deficits, hearing impairment, and vision loss. We previously reported that epithelial cells in amniotic membranes of placentas from newborns with intrauterine growth restriction and underlying congenital HCMV infection contain viral proteins in cytoplasmic vesicles. Herein, we immunostained amniotic membranes from 51 placentas from symptomatic and asymptomatic congenital infection with HCMV DNA in amniotic fluid and/or newborn saliva, intrauterine growth restriction, preterm deliveries, and controls...

Human cytomegalovirus (HCMV) has been recognized as a cause of severe, sometimes life-threatening disease in congenitally infected newborns as well as in immunocompromised individuals. However, the molecular mechanisms of the host-virus interaction remain poorly understood. Here, we profiled the expression of mRNAs and long noncoding RNAs (lncRNAs) in THP-1 cells using the emerging RNA-seq to investigate the transcriptional changes during HCMV latent infection. At 4 days post HCMV infection, a total of 169,008,624 sequence reads and 180,616 transcripts were obtained, respectively...

Tuberculosis is a serious public health problem worldwide. In 2012, the World Health Organization estimated 8.6 million new cases and 1.3 million deaths due to the disease. In 2011, the incidence in Colombia was 24 cases per 100,000 inhabitants. There is little information about tuberculosis in pregnant women, and congenital infection is considered a rare disease that is difficult to diagnose, leads to high mortality, and may be confused with tuberculosis acquired after birth. In addition, it has been associated with HIV infection in mothers and infants...

PURPOSE OF REVIEW: The purpose of review is to assess the recent studies of therapy of pregnant women and neonates, aimed at preventing the consequences of congenital cytomegalovirus (CMV) infection. RECENT FINDINGS: A recent randomized controlled trial of treatment of CMV during pregnancy with hyperimmune globulin did not show significant efficacy in prevention of foetal infection and morbidity, although there was a trend towards improvement with treatment. Trials of antiviral therapy of the mother during pregnancy have involved small numbers only, confounded by ethical and practical difficulties, and further studies are needed to demonstrate whether or not antivirals are useful and well tolerated in this setting...

HIV-exposed uninfected (HEU) infants experience increased overall mortality from infectious causes when compared to HIV-unexposed uninfected (HU) infants. This is the case in both the resource-rich and resource-limited settings. Here, we explore the concept that specific types of infectious diseases that are more common among HEU infants could provide clues as to the potential underlying immunological abnormalities. The most commonly reported infections in HEU vs. HU infants are caused by encapsulated bacteria, suggesting the existence of a less effective humoral (antibody, complement) immune response...

BACKGROUND:  Cytomegalovirus (HCMV) infection causes disease in newborns and transplant recipients. A HCMV vaccine (Towne) protects transplant recipients. METHODS:  The genomes of Towne and unattenuated Toledo strain were recombined yielding four Towne/Toledo chimera vaccines. Each of 36 HCMV-seronegative men received one subcutaneous dose at 10, 100, or 1000 pfu in cohorts of three. Safety and immunogenicity were evaluated over 12 weeks post-immunization and 52 weeks for those seroconverting...

BACKGROUND Because there are clear benefits to breast milk over formula for infants, the goal of the World Health Organization is to increase breastfeeding rates. As more women are breastfeeding and providing breast milk to newborns in hospitals, there is increased risk for administration error. CASE REPORT A hospitalized preterm infant was breastfed by the wrong mother when the Neonatal Intensive Care Unit Nurse failed to properly identify the mother. An infectious disease workup done on the donor mother was negative, but the recipient infant was positive for cytomegalovirus (CMV)...

UNLABELLED: Congenital cytomegalovirus (CMV) infection is a leading cause of mental retardation and deafness in newborns. The guinea pig is the only small animal model for congenital CMV infection. A novel CMV vaccine was investigated as an intervention strategy against congenital guinea pig cytomegalovirus (GPCMV) infection. In this disabled infectious single-cycle (DISC) vaccine strategy, a GPCMV mutant virus was used that lacked the ability to express an essential capsid gene (the UL85 homolog GP85) except when grown on a complementing cell line...

UNLABELLED: Human cytomegalovirus (HCMV) is an enveloped double-stranded DNA virus that causes severe disease in newborns and immunocompromised patients. During infection, the host cell endosecretory system is remodeled to form the cytoplasmic virion assembly complex (cVAC). We and others previously identified the conserved, multifunctional HCMV virion tegument protein pUL103 as important for cVAC biogenesis and efficient secondary envelopment. To help define its mechanisms of action and predict additional functions, we used two complementary methods, coimmunoprecipitation (co-IP) and proximity biotinylation (BioID), to identify viral and cellular proteins that interact with pUL103...

BACKGROUND: In preterm infants cytomegalovirus (CMV) infection acquired through maternal milk has been related to morbidity. However, infants who may receive higher titers of protective antibodies from highly seropositive mothers have not been studied in detail. METHODS: A cohort of 188 ≤30-week-old infants was monitored from admission to discharge. CMV-DNA, hematology, liver enzymes, neutralizing antibodies, and CMV-DNA-lactia were tested periodically. RESULTS: Mothers of 157 infants (83...

BACKGROUND: Congenital cytomegalovirus (CMV) infection is the leading infectious cause of birth defects, mental retardation and non-genetic sensorineural hearing loss. Murine models have been developed in order to understand the pathophysiological mechanisms underlying these lesions. These models are being proposed for the validation of therapeutic protocols for clinical use. The aim of this preclinical study was to assess the pharmacokinetics of the reference antiviral molecule, ganciclovir, in order to optimize these protocols and confirm the diffusion of the molecule to the appropriate target zones...

UNLABELLED: Human cytomegalovirus (HCMV) pUL93 and pUL77 are both essential for virus growth, but their functions in the virus life cycle remain mostly unresolved. Homologs of pUL93 and pUL77 in herpes simplex virus 1 (HSV-1) and pseudorabies virus (PRV) are known to interact to form a complex at capsid vertices known as the capsid vertex-specific component (CVSC), which likely stabilizes nucleocapsids during virus maturation and also aids in nuclear egress. In herpesviruses, nucleocapsids assemble and partially mature in nuclear replication compartments and then travel to the inner nuclear membrane (INM) for nuclear egress...
