The Use of Saliva Samples to Test for Congenital Cytomegalovirus Infection in Newborns: Examination of False-Positive Samples Associated with Donor Milk Use.

A universal screening research study was conducted in six hospitals to identify the clinical sensitivity of polymerase chain reaction (PCR) testing on newborn dried blood spots (DBSs) versus saliva specimens for the diagnosis of congenital cytomegalovirus (cCMV). CMV DNA positive results from DBSs or saliva were confirmed with urine testing. Findings of several false-positive (FP) saliva PCR results prompted an examination of a possible association with donor milk.

Early childhood outcomes of NICU graduates with cytomegalovirus infection in California.

Background: To assess demographics and outcomes up to 3 years of age among children with cytomegalovirus (CMV) infection in California neonatal intensive care units (NICUs) during 2010-2021.

Methods: The California Perinatal Quality Care Collaborative (CPQCC) collects data on all very low birth weight (VLBW, birth weight ≤ 1500 g) and acutely ill infants with birth weight > 1500 g across 92% of NICUs in California. VLBW infants and those with neurological conditions are referred to a statewide high-risk infant follow-up (HRIF) program.

Assessment of Congenital Cytomegalovirus Prevalence Among Newborns in Minnesota During the COVID-19 Pandemic.

This cross-sectional study assesses the prevalence of congenital cytomegalovirus infection among newborns screened in Minnesota before and during the COVID-19 pandemic.

A Legal Mapping Assessment of Cytomegalovirus-Related Laws in the United States.

Importance: Congenital cytomegalovirus (CMV) infection is the leading infectious cause of birth defects in the United States, affecting approximately 1 out of 200 newborns. Increasing awareness of congenital CMV infection among policy makers and the public is critical for advancing the evidence base for prevention and intervention strategies, including behavioral interventions for pregnant women, newborn screening to enable timely interventions, and garnering support for vaccine development.

Objective: To understand the current landscape of CMV-related statutes and regulations, we conducted a 50-state legal epidemiology study of laws expressly referencing "cytomegalovirus.

Enhanced throughput of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) real-time RT-PCR panel by assay multiplexing and specimen pooling.

A multiplex real-time reverse transcriptase-polymerase chain reaction (rRT-PCR) assay for detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was developed based on the same primer and probe sequences of an existing U.S. CDC Emergency Use authorized test panel, targeting SARS-CoV-2 N1, N2 and human RNase P genes in singleplex.

Economic assessments of the burden of congenital cytomegalovirus infection and the cost-effectiveness of prevention strategies.

Objective: This is a critical review of published economic analyses on congenital cytomegalovirus infection and strategies for its detection and prevention.

Findings: The review identified four cost-of-illness studies and nine cost-effectiveness analyses: three of vaccination of young women, two of prenatal screening, and four of newborn screening. All reported either large economic costs or favorable cost-effectiveness of interventions.

Sensitivity of Dried Blood Spot Testing for Detection of Congenital Cytomegalovirus Infection.

Importance: The sensitivity of dried blood spots (DBS) to identify newborns with congenital cytomegalovirus (cCMV) infection has not been evaluated in screening studies using the current, higher-sensitivity methods for DBS processing.

Objective: To assess the sensitivity of DBS polymerase chain reaction (PCR) for newborn screening for cCMV infection using saliva as the reference standard for screening, followed by collection of a urine sample for confirmation of congenital infection.

Design, Setting, And Participants: This population-based cohort study took place at 5 newborn nurseries and 3 neonatal intensive care units in the Minneapolis/Saint Paul area in Minnesota from April 2016 to June 2019.

Late-onset Hearing Loss From Congenital Cytomegalovirus Infection After Newborn Period in a Highly Immune Population in China.

After following 141 children with likely asymptomatic congenital cytomegalovirus infection in a highly immune population in China, four children (2.8%) were found to have late-onset hearing loss. No maternal or childhood factors, except higher saliva cytomegalovirus viral load at birth (P = 0.

Donor-derived human herpesvirus 8 and development of Kaposi sarcoma among 6 recipients of organs from donors with high-risk sexual and substance use behavior.

Kaposi sarcoma (KS) can develop following organ transplantation through reactivation of recipient human herpesvirus 8 (HHV-8) infection or through donor-derived HHV-8 transmission. We describe 6 cases of donor-derived HHV-8 infection and KS investigated from July 2018 to January 2020. Organs from 6 donors, retrospectively identified as HHV-8-positive, with a history of drug use disorder, were transplanted into 22 recipients.

Evaluation of rapid and sensitive DNA extraction methods for detection of cytomegalovirus in dried blood spots.

Background: Dried blood spots (DBS), collected universally from newborns in the U.S., could be used as a matrix for the detection of cytomegalovirus (CMV) infection in infants.

CMV on surfaces in homes with young children: results of PCR and viral culture testing.

Background: Caring for young children is a known risk factor for cytomegalovirus (CMV) infection mainly through exposure to their saliva and urine. In a previous study, 36 CMV-seropositive children 2 mo. to 4 years old were categorized as CMV shedders (n = 23) or non-shedders (n = 13) based on detection of CMV DNA in their saliva and urine.

Viral Loads in Congenital Cytomegalovirus Infection From a Highly Immune Population.

Among newborns with congenital cytomegalovirus (CMV) infection from China, there was no difference in CMV viral load in saliva specimens dried and stored at room temperature compared with those kept wet and stored cold, even after longer storage time for the former than the later (74 vs 58 days, P = .02).

Urinary Cytomegalovirus Shedding in the United States: The National Health and Nutrition Examination Surveys, 1999-2004.

Background: There are no data on the prevalence of cytomegalovirus (CMV) shedding from a representative sample of the US population. This information is critical for understanding and preventing CMV.

Methods: We tested urine specimens from CMV immunoglobulin (Ig) G-positive participants aged 6-49 years in 3 racial/ethnic groups from the National Health and Nutrition Examination Surveys 1999-2004 for the presence of CMV DNA using real-time polymerase chain reaction assay.

Valganciclovir Use Among Commercially and Medicaid-insured Infants With Congenital CMV Infection in the United States, 2009-2015.

Purpose: The aim of this study was to assess the clinical characteristics and trends in valganciclovir use among infants diagnosed with congenital cytomegalovirus (CMV) disease in the United States.

Methods: We analyzed data from medical claims dated 2009-2015 from the Truven Health MarketScan Commercial Claims and Encounters and Medicaid databases. We identified infants with a live birth code in the first claim who were continuously enrolled for at least 45 days.

Donor-derived Kaposi's sarcoma in a liver-kidney transplant recipient.

Human herpes virus 8 (HHV-8), also known as Kaposi's sarcoma associated herpesvirus (KSHV), is an oncogenic virus that can cause Kaposi's sarcoma (KS). KS can develop following organ transplantation through reactivation of the recipient's latent HHV-8 infection, or less commonly through donor-derived infection which has higher risk for severe illness and mortality. We describe a case of probable donor-derived KS in the recipient of a liver-kidney transplant.
