Cranial Ultrasound Findings in Infants With Congenital Cytomegalovirus Infection in a Universal Newborn Screening Study in Minnesota. J Pediatric Infect Dis Soc 2024; 13:413-420. [PMID: 38847778 DOI: 10.1093/jpids/piae059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 06/06/2024] [Indexed: 08/25/2024]
Abstract
BACKGROUND Congenital cytomegalovirus (cCMV) is the most common infectious cause of neurodevelopmental deficits in US children. To inform patient management, it is important to define whether central nervous system (CNS) manifestations are present at birth. This study characterized neuroimaging findings in infants with cCMV identified by a universal screening study in Minnesota during February 2016-December 2022. METHODS Newborns with cCMV infection (confirmed by urine CMV polymerase chain reaction [PCR] testing, obtained following a positive screening saliva and/or dried blood spot result) underwent a diagnostic evaluation that included a cranial ultrasound (cUS) exam, laboratory studies, ophthalmological, and audiological evaluation. Neuroimaging findings and cCMV disease classification were interpreted based on international consensus guidelines. RESULTS Among 87 newborns with confirmed cCMV, 76 underwent cUS. Of these, 53/76 (70%) had normal examinations, while 23/76 (30%) exhibited cUS findings: for 5 infants, these were clearly cCMV disease-defining, while for 18 infants, there were findings of uncertain significance. Magnetic resonance imaging (MRI) results (n = 10 infants) aligned with cUS cCMV disease-defining findings in 2 infants, while cCMV-specific abnormalities were noted by MRI in 2 of 6 infants with nondiagnostic/incidental cUS findings. Of 9 infants who had both cUS and MRI examination, the average time interval between studies was 220 days (range, 2-1061). Excluding infants with cCMV CNS disease-defining cUS abnormalities, incidental findings were observed more commonly in infants with clinical/laboratory features described in cCMV disease classification guidelines (9/13) than in newborns with completely asymptomatic infections (9/58; P < .0001). CONCLUSIONS Among infants with cCMV identified in a universal screening study, the majority had a normal cUS. CNS disease-defining abnormalities were present in 7%, while 24% had findings of uncertain significance. We propose that many cUS findings are incidental, and not diagnostic of symptomatic cCMV infection. Although these findings may not be sufficient to define the presence of symptomatic cCMV disease involving the CNS, in our study they were more commonly observed in infants with other clinical and/or laboratory findings associated with symptomatic cCMV infection.

Abstract
Congenital cytomegalovirus (CMV) is the most common cause of congenital infection worldwide, the most common nongenetic cause of sensorineural hearing loss in children, and a cause of neurodevelopmental disorders in the brain. Infants with symptomatic congenital CMV infection may benefit from hearing and neurodevelopmental outcomes, particularly if antiviral treatment is initiated within the first month of life. Infants with life-threatening symptoms are recommended to receive 2-6 weeks of intravenous ganciclovir and then switch to oral valganciclovir, and those without life-threatening symptoms are recommended to use oral valganciclovir during the entire 6-month period. During antiviral drug treatment, absolute neutrophil count, platelet count, blood urea nitrogen, creatinine, and liver function tests were performed to identify neutropenia, thrombocytopenia, renal failure, and liver failure. This review investigated the evidence to date of treating congenital CMV infection.

Role of Valganciclovir in Children with Congenital CMV Infection: A Review of the Literature. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1246. [PMID: 37508743 PMCID: PMC10378502 DOI: 10.3390/children10071246] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 07/15/2023] [Accepted: 07/17/2023] [Indexed: 07/30/2023]
Abstract
BACKGROUND Cytomegalovirus (CMV) is the most common agent of congenital infection in humans. It is a main cause of neurodevelopmental delay and sensorineural hearing loss in infancy. Since the 2000s, a number of studies have used Valganciclovir as a therapy for children with congenital CMV infection. METHODS In order to evaluate the efficacy of Valganciclovir in preventing clinical sequelae and its possible side effects, we performed a review of the published literature. This search was completed via PubMed for manuscripts published from January 2007 to December 2021, combining the MeSH words "Valganciclovir", "Congenital", and "Cytomegalovirus". RESULTS A total of 27 articles were included (12 retrospective studies, 4 prospective studies, 1 randomized controlled trial, and 10 case reports). The clinical features were similar to those already described in the literature. The therapeutic protocols used were very different between the various studies included and neonatal antiviral treatments were only moderately effective. The therapy proved to be well-tolerated. CONCLUSIONS The quality of the included studies and the sample size were limited due to the rarity of the disease. The use of different therapeutic protocols in terms of starting dates, doses, and durations made it impossible to compare and correctly evaluate the efficacy of the treatments. Randomized controlled trials are needed to establish the correct effective dose with the fewest side effects and the most efficient duration of therapy.

Abstract
BACKGROUND Congenital cytomegalovirus (CMV) infection is an important cause of disability. There is little evidence on the prognostic value of lesions identified in neuroimaging studies. AIM The study aimed to assess the severity of lesions detected with brain MRI and transfontanellar ultrasound and their relationship with long-term neurological deficits. PATIENTS AND METHODS We performed a retrospective, analytical, observational study of 36 patients with congenital CMV infection. Neuroimaging studies were reviewed and classified according to the modified Noyola' scale. Imaging findings were compared with neurological alterations in the patients' most recent follow-up evaluation at the paediatric neurology department. RESULTS Thirty-six patients were studied (transfontanellar ultrasound: 30; brain MRI: 29). Twenty of 30 patients showed ultrasound abnormalities; of these, 11 showed alterations on brain MR images (P=.04) and 10 had neurological impairment (P=.008). Transfontanellar ultrasound had a sensitivity of 83.3%, 90% CI: 58-100 and a specificity of 44.4%, 90% CI: 18.7-70.2 for predicting neurological sequelae. Brain MRI displayed abnormalities in 20 of 29 patients, of whom 16 had neurological impairment (P<.001). MRI had a sensitivity of 94%, 95% CI: 80-100 and a specificity of 66.6%, 95% CI: 36-97.5 for predicting neurological sequelae. Modified Noyola' scale values >2 were correlated with psychomotor retardation (P<.001). CONCLUSIONS Our findings validate previous studies reporting a statistical significant correlation between the extension of neuroimaging lesions and severity of neurological deficits.

Abstract
OBJECTIVE To search for existing evidence of a beneficial effect of (val)ganciclovir on hearing in children with congenital cytomegalovirus (cCMV) infection and to identify future research questions. STUDY DESIGN Systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, searches were performed in PUBMED, EMBASE, and WEB OF SCIENCE on December 15, 2021. METHODS Studies providing ear-specific hearing results after treating children with cCMV-related hearing loss with (val)ganciclovir were retained. A meta-analysis [Peto odds ratio (OR), Review Manager 5.3] was performed to compare hearing outcome between treated and untreated children. The National Institutes of Health tool was used for quality assessment and heterogeneity was assessed with I2 statistics. RESULTS Eighteen studies with a total of 682 treated patients were included for the systematic review. Our meta-analysis showed that treating symptomatic children with hearing loss resulted in more hearing improvement [Peto OR 7.72, 95% confidence interval (CI) 3.08-19.34] and less hearing deterioration (Peto OR 0.23, 95% CI 0.10-0.57). Relative to an improvement and deterioration rate of 9.4% and 28.2% in an untreated group, the rate of the treated group was 44.5% and 6.3%, respectively. CONCLUSIONS There is sufficient evidence in literature to support treatment with (val)ganciclovir of children with symptomatic cCMV and hearing loss. However, still today, there is insufficient evidence of the potential beneficial role of (val)ganciclovir on hearing outcome of children with isolated hearing loss, late-onset hearing loss, and asymptomatic cCMV. The urgent need for future prospective, randomized clinical trials still exists. A standardization of definitions and treatment protocols would create uniformity in future studies.

Abstract
OBJECTIVE Permanent hearing loss is an important public health issue in children with consequences for language, social, and academic functioning. Early hearing detection, intervention, and monitoring are important in mitigating the impact of permanent childhood hearing loss. Congenital cytomegalovirus (CMV) infection is a leading cause of hearing loss. The purpose of this review was to synthesize the evidence on the association between CMV infection and permanent childhood hearing loss. DESIGN We performed a systematic review and examined scientific literature from the following databases: MEDLINE, Ovid MEDLINE(R) Daily and Ovid MEDLINE(R), Embase, and CINAHL. The primary outcome was permanent bilateral or unilateral hearing loss with congenital onset or onset during childhood (birth to 18 years). The secondary outcome was progressive hearing loss. We included studies reporting data on CMV infection. Randomized controlled trials, quasi-experimental studies, nonrandomized comparative and noncomparative studies, and case series were considered. Data were extracted and the quality of individual studies was assessed with the Qualitative Assessment Tool for Quantitative Studies (McMaster University). The quality and strength of the evidence were graded using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). A narrative synthesis was completed. RESULTS Sixty-five articles were included in the review. Prevalence of hearing loss at birth was over 33% among symptomatic CMV-infected newborns and less than 15% in asymptomatic infections. This difference in prevalence was maintained during childhood with more than 40% prevalence reported for symptomatic and less than 30% for asymptomatic CMV. Late-onset and progressive hearing loss appear to be characteristic of congenital CMV infections. Definitions of hearing loss, degree of loss, and reporting of laterality varied across studies. All degrees and both bilateral and unilateral loss were reported, regardless of symptomatic and asymptomatic status at birth, and no conclusions about the characteristics of hearing loss could be drawn. Various patterns of hearing loss were reported including stable, progressive, and fluctuating, and improvement in hearing (sometimes to normal hearing) was documented. These changes were reported in children with symptomatic/asymptomatic congenital CMV infection, presenting with congenital/early onset/late-onset hearing loss and in children treated and untreated with antiviral medication. CONCLUSIONS Symptomatic and asymptomatic congenital CMV infection should be considered a risk factor for hearing loss at birth and during childhood and for progressive hearing loss. Therefore, CMV should be included as a risk factor in screening and surveillance programs and be taken into account in clinical follow-up of children with hearing loss.

Abstract
OBJECTIVE To describe the prognosis of subtle findings on fetal brain imaging in pregnant women with primary CMV infection during pregnancy. METHODS This was a retrospective study. The data included: timing of infection, amniocentesis results, imaging findings, obstetric outcome, and developmental assessment. RESULTS For the 27 included patients, the time of infection was: periconception, first, second, third trimesters or unknown in 14.8%, 29.7%, 40.7%, 7.4%, and 7.4%, respectively. Seventy-four percent had only MRI findings; white matter hyperintense T2 signal (HT2) (51.8%), mild ventriculomegaly (18.5%), HT2 and temporal cyst (7.4%), dilated occipital horn (7.4%), Periventricular pseudo cyst (PVPC) with dilated occipital horn (3.7%), isolated PVPC (7.4%), choroid plexus cyst (3.7%). In 26% of fetuses, additional ultrasound findings were observed: Lenticulostriatal vasculopathy (LSV) (11.1%), LSV with PVPC (3.84%), isolated PVPC (3.84%), mild ventriculomegaly (3.84%), and bilateral temporal cysts (3.84%). In 66.6%, the MRI had false-positive findings (due to noninfected neonates). All children are developing normally, and one has a hearing deficit. Postnatal ultrasound (US) was normal in 21/27, with LSV in five, and a resolving subependymal cyst in one patient. CONCLUSION Subtle imaging findings are more common on MRI than US and the prognosis is most likely favorable. Performing amniocentesis will significantly reduce the false-positive rate.

Abstract
OBJECTIVE To determine the frequency of abnormal findings on evaluation of neonates with congenital CMV infection who have a normal physical examination STUDY DESIGN: Retrospective, 2-center study (1996-2017) that reviewed results of complete blood cell count and platelets, serum alanine aminotransferase (ALT) and bilirubin concentrations, eye examination, cranial ultrasonography or other neuroimaging, and brainstem evoked responses performed on neonates with congenital CMV infection and a normal physical examination RESULTS: Of 34 infants with congenital CMV infection and a normal physical examination, 56% (19/34) had ≥1 abnormality: 39%, elevated ALT concentration; 45%, abnormal neuroimaging (five, lenticulostriate vasculopathy; six, intraventricular hemorrhage; four, calcifications); 12%, anemia; 16%, thrombocytopenia; and 3%, chorioretinitis. Seven (21%) infants had sensorineural hearing loss, and 18 infants received antiviral therapy. CONCLUSION Some infants with congenital CMV infection and a normal physical examination had abnormalities on laboratory or neuroimaging evaluation, which in some cases prompted antiviral treatment.

Abstract
Human cytomegalovirus (CMV) is a highly prevalent herpesvirus worldwide. According to the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), CMV infects people of all ages, and by the age of five, approximately one-third of children in the United States are infected. Although the infection is generally asymptomatic, it can cause severe disease in immunocompromised patients, transplant and transfusion recipients, as well as newborn neonates. The objective of this study is to systematically review published literature on CMV in the MENA region to estimate its incidence in the region and describe its epidemiological and clinical significance. The literature was searched through four scientific databases: PubMed, Scopus, Science Direct, and Web of Science. A total of 72 studies from 11 countries satisfied the inclusion criteria, covering a period from 1988-2019. The CMV IgG seroprevalence ranged from 8.7%-99.2% (SD = 38.95%). CMV incidence in these countries ranged between 1.22% and 77% in transplant and transfusion recipients, with an increase in incidence with advanced age. However, the incidence rate was unclear for congenital CMV due to the variability of the reporting. This review highlights the need for more robust and well-designed studies to better estimate CMV incidence in the MENA region, standardize diagnostic criteria, and consider prophylactic and pre-emptive treatments to limit the morbidity and mortality of the disease.

Abstract
BACKGROUND Valganciclovir (2/d) therapy for 6 months in neonates with symptomatic congenital cytomegalovirus (cCMV) infection improves hearing and neurodevelopmental outcome. The only reported adverse event was neutropenia. Since 2009, our protocol for symptomatic cCMV infection was a 1-year treatment of 2/d for the first 3 months followed by 9 months of 1/d. METHODS A retrospective study. Infants with cCMV treated with valganciclovir for 1 year were recruited. Data of drug-related hematologic adverse events were collected. RESULTS One hundred sixty infants were eligible; 46 (28.8%) had experienced at least 1 episode of neutropenia (58 episodes), the majority (39/46, 84.8%) during the first 3 months of treatment and 7 (15.2%) during the last 9 months of treatment. Grades 3 and 4 neutropenia occurred in 9 (5.6%) children, almost exclusively during the first 3 months of treatment. Anemia (hemoglobin <9 g/dL) was recorded in 12 (7.5%) children during the first 3 months of 2/d treatment. Four children presented with hemoglobin levels <7 g/dL and needed a blood transfusion. One child was diagnosed with transient pure red cell aplasia. No long-term adverse events were recorded. CONCLUSIONS Although prolonged valganciclovir treatment for cCMV is safe, a close monitoring of the white blood cell count and hemoglobin levels is warranted. Much lower rates of grades 3 and 4 neutropenia were observed than previously reported, probably owing to our unique treatment protocol. Nevertheless, drug-induced anemia should be of primary concern. The optimal protocol assessing clinical outcome, concurrently with potential side effects, has not yet been determined.

Abstract
BACKGROUND The accurate stratification of infants with congenital cytomegalovirus (CMV) infection at risk for more severe outcome may help in the management of patients. Aim of this study was to investigate the ability of a comprehensive neuroimaging investigation in predicting the long-term neurodevelopmental outcome in patients with congenital CMV. We analyzed the prognostic accuracy of a traditional score and a recently proposed scale applied to head ultrasound (HUS), computed tomography (CT) and magnetic resonance imaging (MRI). METHODS All consecutive neonates born from 2002 to 2015 with congenital CMV infection were considered eligible for the study. Neuroimaging findings were scored according to both scores. RESULTS One hundred seventy infants were included (112 symptomatic patients). One-hundred eighteen infants received both HUS, CT and MRI. CT and MRI were normal in all 56 asymptomatic patients, while 32% of them presented an abnormal HUS. The prevalence of abnormal findings differed according to the neuroimaging study. The sensitivity of the new neuroimaging score in detecting patients at risk for poor neurologic outcome was higher than the traditional one for all neuroimaging examinations. CT and MRI showed higher positive predictive value compared with HUS. No neuroimaging examination showed a negative predictive value equal to 100%. CONCLUSIONS Although HUS is the safest neuroimaging technique, it performs less well in detecting some brain abnormalities that can be associated with a poor neurodevelopmental outcome. A comprehensive neuroimaging evaluation is mandatory in infants with congenital CMV infection to decide for treatment and make a prognostic evaluation.

Abstract
PURPOSE To determine the frequency of obstetrical adverse events and clinical outcome in infants following antenatal hyperimmune globulin (HIG) treatment for primary cytomegalovirus (CMV) infection in pregnancy. METHODS Data from 50 women including three twin pregnancies were retrospectively evaluated. Primary infection was defined by seroconversion or the presence of CMV-specific IgM and low IgG avidity. All women received two or more infusions of HIG (200 U/kg). Congenital CMV (cCMV) infection was diagnosed by detection of CMV in amniotic fluid and/or neonatal urine. We compared gestational age (GA) at birth, head circumference (HC) and birth weight (BW) of infants in our study cohort with those of live-born infants delivered in our clinic between 2015 and 2016. RESULTS Median gestational age at time of maternal CMV diagnosis was 13 weeks. One-hundred-forty-one maternal HIG doses were given. No HIG-related severe adverse reactions occurred. Preterm birth rate was 4.2% (2/47) in singleton pregnancies. None of the neonates had birth weight or head circumference < 3rd percentile (< 3P) for gestational age. There was no statistically significant difference regarding GA, BW and HC between our study cohort and the total population of live-born infants. The frequency of CMV-related sequelae in infants with cCMV infection was 10.5% (2/19) (one with bilateral hearing loss and one with mild motoric delay), both cases following first trimester maternal infection. CONCLUSION Antenatal HIG treatment was well tolerated and not associated with prematurity or decreased birth weight. HIG application might have a favorable effect on the clinical course of congenital CMV infection.

Abstract
BACKGROUND Congenital cytomegalovirus (cCMV) infection is an important cause of hearing loss and neurodevelopment delay. While data on vertical transmission and neonatal outcome after singleton pregnancy with cCMV are well established, only scarce reports have addressed cCMV in multiple birth pregnancies. Furthermore, no studies have yet compared the outcome after birth and long-term follow-up of children with cCMV born after a singleton versus multiple pregnancies. METHODS Infant outcome after birth of symptomatic versus asymptomatic infection was compared for infants born with cCMV after multiple (study group) and singleton (control group) pregnancies in a 1:2 ratio. RESULTS Of 508 infants diagnosed with cCMV, 25 (4.9%) were born after a multiple pregnancy. Children in the study and control groups did not differ in terms of specific prenatal CMV investigations including amniocentesis and brain magnetic resonance imaging studies. However, prematurity rates were significantly higher in the study compared with control group (52% vs. 4%, P < 0.001). There was a higher rate of symptomatic cCMV infection in the study group than in the controls (48% vs. 14%, P < 0.001). Hearing impairment at birth was also more frequent in the study group (32% vs. 8%, P = 0.016). A long-term follow-up demonstrated that children in the study group had higher rates of neurologic sequelae (hearing impairment or neurodevelopmental delay) compared with children in the control group (20% vs. 4%, P = 0.016). CONCLUSIONS Infants with cCMV born after multiple birth pregnancies are born earlier and have a higher risk of symptomatic disease at birth and worse long-term neurologic outcome than those born after a singleton pregnancy. This important group of children warrants meticulous prenatal and postnatal care.

Abstract
BACKGROUND Lenticulostriated vasculopathy (LSV) detected in head ultrasound (HUS) has been related to neurological and hearing sequelae in infants with congenital cytomegalovirus (cCMV) infection. OBJECTIVE To assess the role of LSV in predicting neurodevelopmental and hearing outcomes in infants with cCMV infection. STUDY DESIGN We enrolled consecutive infants who were affected by cCMV infection and underwent HUS within the first month of life. Data on clinical onset and course, laboratory findings, visual/hearing functions and neurodevelopmental outcome were collected. As controls, infants with suspected intrauterine exposure to Toxoplasma and with no confirmed congenital toxoplasmosis were considered. RESULTS Data from 161 infants with cCMV infection (105 symptomatic) and 133 controls were analyzed. HUS was normal in 66 (41%) cCMV patients. Among these, 28 (42.4%) were symptomatic and 38 (57.6%) asymptomatic infants. The percentage of patients with no HUS abnormalities was higher in asymptomatic (38/56, 67.9%) than in symptomatic infants (28/105, 26.7%) (p<0.05). LSV, as isolated or associated with other brain abnormalities, was diagnosed in 64/161 (39.7%) patients with cCMV compared to 24/133 (18%) controls (p<0.05). In cCMV group, LSV was found in 51 (48.6%) symptomatic infants and in 13 (72.2%) asymptomatic patients (p>0.05). Overall, in the whole population of 95 patients with cCMV and abnormal HUS results, LSV (alone or with other findings) did not represent a risk factor for unfavorable neurological and hearing outcome. Similar results were obtained when we limited the analysis to the group of symptomatic cCMV patients. CONCLUSIONS Although LSV is a common HUS finding in infants with cCMV infection, its presence is not predictive of an adverse outcome. Our data suggest that HUS as a single neuroimaging investigation is unreliable in selecting candidates to antiviral therapy, mainly in presence of LSV as isolated finding.

Abstract
Neonatal serum detection of cytomegalovirus (CMV) immunoglobulin M (IgM) has low sensitivity in identifying congenital cytomegalovirus (cCMV). Several reports have endeavored to associate the presence/absence of IgM to disease severity. Data were collected for all infants with cCMV followed in our clinic. Infant outcome after birth was compared between infants who tested positive or negative. Sensitivity of positive IgM in diagnosing cCMV was 40.7%. The rate of symptomatic disease in those who tested positive was statistically higher (67.7%, P < .001). Odds ratio for symptomatic disease in infants with positive IgM born after a maternal primary infection was 3.47 (95% confidence interval = 1.7-7.1). Positive IgM was found in only 48.8% of symptomatic and 22.1% of asymptomatic children. Our results demonstrated a low sensitivity of IgM in diagnosing cCMV. However, while a positive IgM antibody for CMV is associated with a more symptomatic disease, it does not serve as a precise laboratory marker for a severity.

Abstract
Importance Zika virus infection can be prenatally passed from a pregnant woman to her fetus. There is sufficient evidence to conclude that intrauterine Zika virus infection is a cause of microcephaly and serious brain anomalies, but the full spectrum of anomalies has not been delineated. To inform pediatric clinicians who may be called on to evaluate and treat affected infants and children, we review the most recent evidence to better characterize congenital Zika syndrome. Observations We reviewed published reports of congenital anomalies occurring in fetuses or infants with presumed or laboratory-confirmed intrauterine Zika virus infection. We conducted a comprehensive search of the English literature using Medline and EMBASE for Zika from inception through September 30, 2016. Congenital anomalies were considered in the context of the presumed pathogenetic mechanism related to the neurotropic properties of the virus. We conclude that congenital Zika syndrome is a recognizable pattern of structural anomalies and functional disabilities secondary to central and, perhaps, peripheral nervous system damage. Although many of the components of this syndrome, such as cognitive, sensory, and motor disabilities, are shared by other congenital infections, there are 5 features that are rarely seen with other congenital infections or are unique to congenital Zika virus infection: (1) severe microcephaly with partially collapsed skull; (2) thin cerebral cortices with subcortical calcifications; (3) macular scarring and focal pigmentary retinal mottling; (4) congenital contractures; and (5) marked early hypertonia and symptoms of extrapyramidal involvement. Conclusions and Relevance Although the full spectrum of adverse reproductive outcomes caused by Zika virus infection is not yet determined, a distinctive phenotype-the congenital Zika syndrome-has emerged. Recognition of this phenotype by clinicians for infants and children can help ensure appropriate etiologic evaluation and comprehensive clinical investigation to define the range of anomalies in an affected infant as well as determine essential follow-up and ongoing care.

Abstract
BACKGROUND Recently, congenital cytomegalovirus (cCMV) infection was reported irrespective of a negative amniotic fluid prenatal analysis for cytomegalovirus (CMV). The question of whether this phenomenon represents low sensitivity of the test or late development of fetal infection (after amniocentesis) was discussed, but not answered. However, if late transmission is the rule, then infants born with cCMV after negative amniocentesis would be expected to carry better prognosis than those who tested positive. METHODS Data of all infants with cCMV infection, followed in 2 pediatric centers from 2006 to 2015, were reviewed. Infant outcome after birth of symptomatic vs asymptomatic disease was compared with infants born after a negative amniocentesis (study group) and those with a positive amniocentesis (control group). RESULTS Amniocentesis was performed in 301 pregnancies of our cohort of infants with cCMV and was negative for CMV in 47 (15.6%). There were fewer symptomatic cCMV neonates in the study group than in the control group (4.3% vs 25%; P < .001). Hearing impairment at birth was also less frequent in the study group (2.2% vs 17.4%; P = .012). None of the children in the study group had neurologic sequelae at long-term follow up, compared with 13 (14.1%) in the control group (P < .001). CONCLUSIONS Although negative amniocentesis does not exclude cCMV, infants with cCMV born after a negative amniocentesis seldom present with mild clinical symptoms or cerebral ultrasound features at birth. These children also have a very good long-term outcome. Our findings support the theory of a late development of fetal infection, after the time of the amniocentesis.

Abstract
BACKGROUND Congenital cytomegalovirus (cCMV) can cause brain inflammation/destruction and teratogenic effects. The only validated neuroimaging prognostic categorization for symptomatic cCMV available is based on destructive lesions seen on computed tomography (CT). OBJECTIVE The aim of this study was to establish the predictive ability of a comprehensive neonatal neuroimaging scale in symptomatic cCMV. METHODS Twenty-six infants were studied by neonatal cranial ultrasound scans (US; n = 25), CT (n = 11) and magnetic resonance imaging (MRI; n = 9). A previously validated neuroimaging scale comprising calcifications, ventriculomegaly and atrophy was compared to a newly proposed system adding cerebral dysgenesis and white matter disease. The findings were graded from 0 to 3. Neurodevelopmental assessment included motor and cognitive functions, epilepsy, vision, hearing and behavioral disorders. RESULTS Both scales showed a significant association with outcome (p < 0.005). Our scale was more accurate in predicting death or moderate-severe disability (area under the curve for scores ≥2, 0.88 ± 0.06 vs. 0.80 ± 0.08). All 5 infants with normal neuroimaging survived with intact neurological function. While our scale was highly associated with outcome in patients studied by MRI, it was unable to predict unfavorable outcomes in 2 patients with mildly abnormal US and/or CT. CONCLUSIONS A comprehensive scale based on US and MRI predicts neurodevelopment in symptomatic cCMV. Significant destructive lesions are associated with a poor prognosis. While a strictly normal cranial US predicts a favorable outcome, in case of subtle US abnormalities, MRI is crucial for prognostication.
