Congenital cytomegalovirus is the most common viral congenital infection, and affects up to 2% of neonates. Significant sequelae may develop after congenital cytomegalovirus, including hearing loss, cognitive defects, seizures, and death. Zika virus is an emerging virus with perinatal implications; a congenital Zika virus syndrome has been identified, and includes findings such as microcephaly, fetal nervous system abnormalities, and neurologic sequelae after birth. Screening, diagnosis, prevention, and treatment of these perinatal infections are reviewed in this article...

BACKGROUND: Congenital cytomegalovirus infection is the leading infectious cause of mental retardation, developmental delay and sensorineural deafness. Non primary infection plays a major role in transmission of this infection in countries with high maternal seroprevalence. Non invasive sampling and testing is a useful alternative to traditional methods of laboratory detection of congenital CMV infection. The present study was conducted to understand birth prevalence of congenital cytomegalovirus (cCMV) infection using molecular techniques, in an urban setting of a developing country with evidence of high maternal seroprevalence...

Cytomegalovirus (CMV) is the most common cause of congenital infection. Pneumonitis is considered to be a rare manifestation although congenital CMV infection presents with various non-specific findings. Ganciclovir and valganciclovir are beneficial for improving neurodevelopmental sequelae and hearing outcome of congenital CMV infection, but treatment response evaluationis not well reported. We report a female case of congenital CMV infectionpresenting with pneumonitis, meningoencephalitis, and chorioretinitis...

Interleukin 33 (IL-33) and soluble form of ST2 (sST2) are involved in inflammation. This study aimed to assess the role of serum IL-33 and sST2 in neonates with HCMV infection. The concentration of serum IL-33 and sST2 in 20 patients and 16 healthy controls were measure by enzyme-linked immune-sorbent assay (ELISA). The clinical and laboratory data were described. Our results showed serum sST2 and IL-33 levels were significantly higher in the HCMV group than the control group. Significant positive correlation was observed between sST2 and IL-33 (r = 0...

Secondary envelopment of human cytomegalovirus (HCMV) occurs through a mechanism that is poorly understood. Many enveloped viruses utilize the endosomal sorting complexes required for transport (ESCRTs) for viral budding and envelopment. Although there are conflicting reports on the role of the ESCRT AAA-ATPase protein VPS4 in an HCMV infection, VPS4 may act in an envelopment role similar to its function during other viral infections. Because VPS4 is normally recruited by the ESCRT-III complex, we hypothesized that ESCRT-III subunits would also be required for HCMV infection...

The term blueberry muffin rash is used to describe the clinical presentation of dermal extramedullary hematopoiesis. The common culprits of this rash include a TORCH (toxoplasmosis, other agents, rubella, cytomegalovirus, herpes) infection or hematologic dyscrasia. Association of this rash with hereditary spherocytosis is extremely rare. We present a unique case of a neonate born with a blueberry muffin rash secondary to hereditary spherocytosis.

Prenatal, neonatal meningoencephalitis and infections of the brain in older infants are often associated with serious complications which can be diagnosed by sonography through the open fontanelles. Most frequently postmeningitic hydrocephalus and subdural effusions occur. Rarer complications are brain abscesses and ventriculitis which are caused by gram negative bacteria such as E. coli, Serratia marcescens, Proteus and Enterobacter. A serious complication after ventriculitis is the development of compartment hydrocephalus...

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...

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. A target area under the concentration-time curve from 0 to 24 h (AUC0-24 ) of 40 to 50 μg · h/ml is recommended. The standard dose has resulted in a large variability in ganciclovir exposure in newborns, indicating the unmet need of dosage individualization for this vulnerable population, but the implementation of this strategy remains challenging in clinical practice...

Human cytomegalovirus (HCMV) is a major human pathogen and is associated with severe pathology, such as life-threatening courses of infection in immunocompromised individuals and neonates. Currently, antiviral therapy is still hampered by a considerable toxicity of the available drugs and induction of viral resistance. Recently, we and others reported the very potent antiviral activity of the broad antiinfective drug artesunate in vitro and in vivo. Here, we investigated further optimized analogs including monomeric, dimeric and trimeric derivatives belonging to this highly interesting chemical group of experimental drugs (sesquiterpenes/trioxanes) and compared these to the previously identified trimeric artesunate compound TF27...

Single gene defects that impair lymphocyte cytotoxicity can predispose to severe viral infection that normally remains subclinical. The classic severe presentation is hemophagocytic lymphohistiocytosis. Here, we report the case of a neonate who presented with cytomegalovirus palatal ulceration and bocavirus pneumonitis secondary to impaired cytotoxicity caused by biallelic mutations in the UNC13D gene.

AIM: Cytomegalovirus (CMV) is associated with neonatal cholestasis (NC). Diagnosis of CMV infection is most often based upon either positive blood CMV IgM or CMV blood PCR. Isolation of CMV in liver tissues in patients with NC has rarely been reported. This study was undertaken to see if CMV is present in liver tissues of patients with NC and evaluate the correlation between positive CMV PCR in liver tissue with the serology and blood PCR. METHODS: This study was conducted in 31 infants with NC from June 2015-Dec 2016...

During gestation, the immune response of the placenta to viruses and other pathogens plays an important role in determining a pregnant woman's vulnerability toward infectious diseases. Located at the maternal- fetal interface, trophoblast cells serve to minimize the spread of viruses between the host and developing fetus through an intricate system of innate antiviral immune signaling. Adverse pregnancy outcomes, ranging from learning disabilities to preterm birth and fetal death, are all documented results of a viral breach in the placental barrier...
