Aim: Congenital cytomegalovirus (cCMV) infection can result in considerable morbidity and mortality. However, the impact of cCMV on health system utilisation beyond infancy is poorly defined. Here we sought to describe the burden of cCMV health service use and mortality using linked population-based datasets., Methods: The design was a matched cohort study using record-linked administrative datasets. Participants included all children aged 0-15 years identified through the New South Wales (NSW), Australia, Admitted Patient Data Collection who were hospitalised with an admission code for cCMV infection between 2001 and 2011. Participants were then matched by age, sex and birth postcode quintile using Socio-Economic Indexes for Area, to children randomly selected from the NSW Perinatal Data Collection, excluding those with central nervous system infections or cerebral palsy. We calculated rate ratios (RR) for hospital admissions adjusted for preterm birth, the median length of stay, cost weights of admission and odds ratio (OR) for deaths., Results: There were 130 children with cCMV matched to 2672 children. Neonates (aged <1 month) with cCMV had twice the rate of admissions (RR 2.4 95%CI 2.0, 2.8) and children aged ≥ 5yr to < 15yrs with cCMV almost eight times the rate of admissions (RR 7.8 95%CI 5.1, 11.5). Children with cCMV had significantly higher cost weights of admissions and an increased risk of mortality (OR 18.4 95%CI 7.8, 43.6)., Conclusion: Throughout childhood, children with cCMV had higher rates of hospital admissions, higher admission cost weights and an increased risk of mortality compared with matched peers without cCMV., (© 2022 Published by Elsevier Ltd on behalf of European Paediatric Neurology Society.)

Objectives: To determine the proportion of children with cerebral palsy (CP) and cytomegalovirus (CMV) DNA detected retrospectively in their newborn screening cards (NBSC), to compare the proportion of children with CMV DNA in their NBSC across spastic subtypes of CP, and to compare the sex and other characteristics of children with CP and CMV detected on their NSBC with those in whom CMV DNA was not detected., Study Design: Retrospective observational study. Data were extracted from patient records on children with CP (birth years 1996-2014) from 2 Australian state CP registers and state-wide paediatric rehabilitation services with consent. NBSCs were retrospectively analyzed for CMV DNA by nested polymerase chain reaction (PCR) using primers against gB. Positive samples were validated using real time PCR for CMV UL83., Results: Of 401 children recruited, 323 (80.5%) had an available NBSC. Of these, 31 (9.6%; 95% CI, 6.8-13.3) tested positive for CMV DNA by nested PCR for CMV gB, of whom 28 (8.7%; 95% CI, 6.1-12.2) also had CMV DNA detected by real-time PCR for CMV UL83. Detection of CMV DNA was significantly associated with epilepsy, but not with clinical or epidemiologic characteristics, including sex and pattern of spasticity., Conclusions: CMV viremia in the newborn period, indicating congenital CMV infection, is highly prevalent among children with CP. Further research is needed to investigate the mechanisms and contribution of congenital CMV to the causal pathways to CP., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Aim: Cytomegalovirus (CMV) is an important cause of congenital infection, which can result in neonatal deaths or contribute to deaths in later childhood. Post-natally acquired CMV is a less common cause of disease and mortality, and only in preterm infants or immunocompromised children. Here we sought to describe CMV as a direct or secondary contributor to childhood mortality in Australia., Method: We searched national mortality data sets between1999 and 2011 for cases <15 years with CMV recorded as an underlying or contributing cause of death., Results: Eighty-three CMV-associated deaths in children <15 years were identified (0.2 cases per 100 000 <15 years; 95% confidence interval 0.16-0.24). Childhood deaths associated with CMV were evenly distributed between males and females, and the majority (n = 57; 68%) occurred in children less than 12 months of age, with 22 cases <1 month of age. Over the 13-year study period, the mortality rate remained stable and CMV resulted in an estimated age-adjusted 5925 years of potential life lost., Conclusions: CMV makes a small but important contribution to childhood mortality in Australia. Most CMV-related deaths occurred in infants <12 months of age. These infant deaths may be an indirect marker of the burden of severe intrauterine CMV disease given the natural history of this infection., (© 2015 The Authors.

Aim: Congenital cytomegalovirus (cCMV) infection can result in poor outcomes including cerebral palsy (CP). The aim of this study was to describe the incidence and comorbidities of CP reported to the Australian Cerebral Palsy Register (ACPR) as attributed to cCMV infection., Method: This was a retrospective population-based study. Cases were drawn from Australian state CP registers with population level ascertainment, 1993 to 2003 (n=2265; 56.4% males, Gross Motor Function Classification System [GMFCS] ratings available for Victorian cases only: 70% GMFCS levels I to III and 30% GMFCS levels IV to V). Clinical data were extracted and cases with cCMV reported as a known cause were compared with cases where cCMV was not reported., Results: Children with cCMV (n=34; 12 males, 22 females; mean [SD] gestational age, 36.4 wk [4.4], range 24-41 wk) accounted for 1.5% of CP cases; 2.9 per 100,000 live births, (95% confidence intervals 1.9-3.9). When compared with CP cases where cCMV was not reported, proportionally, more CP cases with cCMV were born to younger mothers (p<0.001), were female (64% vs 43%, p=0.014), had spastic quadriplegia (73% vs 21%, p<0.001), required wheeled mobility i.e. GMFCS IV or V (78% vs 28%, p<0.001), had epilepsy (70% vs 30%, p<0.001), deafness (40% vs 2%, p<0.001), functional blindness (20% vs 5%, p<0.001), and severe communication impairment (71% vs 25%, p<0.001)., Interpretation: cCMV is an important potentially preventable cause of CP and is associated with severe disability and female sex in cases reported to the ACPR. Future studies utilising prospective sample collection for cCMV testing are needed to confirm these findings., (© 2014 Mac Keith Press.)

Unlabelled: Congenital cytomegalovirus (cCMV) is a contributing cause of neurodevelopmental disabilities including cerebral palsy (CP). In this case series we reviewed the neuroimaging findings of children with CP and cCMV infection in the context of the children's clinical profile., Participants: Children with CP and laboratory confirmed cCMV (n=12) reported to the Australian CP Register, born in South Australia and Victoria, 1993-2006, with magnetic resonance imaging (MRI) and/or computerized tomography (CT) report available. Clinical details and neuroimaging findings were tabulated and compared to published literature. Children in this series were mostly born at term (n=8), with symptoms or signs of cCMV (n=10) and had spastic quadriplegia (n=9), epilepsy (n=8), intellectual deficit (n=12), communication (n=10) and hearing impairments (n=9). All but one had abnormal neuroimaging findings reported on MRI or CT (n=11): most commonly brain malformations including disorders of neuronal migration (n=10), such as lissencephaly, pachygyria and polymicrogyria, and cerebellar hypoplasia (n=5). Other findings included ventricular dilatation (n=8), calcifications (n=7) and white matter abnormalities (n=6). This study suggests that brain malformations, calcifications, ventricular dilatation and cerebellar hypoplasia are common neuroimaging patterns in children with CP and cCMV infection. The presence of these findings should prompt investigations for congenital cytomegalovirus.
