Abstract Cytomegalovirus (CMV) is the leading cause of congenital infection and the most common cause of non-genetic sensorineural hearing loss (SNHL) in childhood. Although most infected infants are asymptomatic at birth, the risk for SNHL and other neurodevelopmental morbidity makes congenital CMV (cCMV) a disease of significance. Adherence to hygienic measures in pregnancy can reduce risk for maternal CMV infection. The prompt identification of infected infants allows early initiation of surveillance and management. A multidisciplinary approach to management is critical to optimize outcomes in affected infants.

AbstractWe describe a case of congenital cytomegalovirus (CMV) infection transmitted by an immunocompetent woman infected before conception with continuous hyper CMV-immunoglobulin M (IgM). A 33-year-old woman whose CMV-IgM levels were stable more than 8 months before conception was referred at 35 gestational weeks due to fetal unilateral cerebral ventriculomegaly. The maternal serum CMV-IgG was 61.7 U/mL, and the CMV-IgM was 3.89 U/mL. An infant girl weighing 2297 g was delivered transvaginally. The neonate was found to have congenital CMV infection. After delivery, the high maternal CMV-IgM level has continued for more than 2 years. In conclusion, although continuous hyper CMV-IgM is rare, the infants of infected women may develop congenital infection. It is our hope that the information provided in the present case will further aid clinicians in counseling patients who find themselves in this situation.

It is a great pleasure mixed with some sadness to write this editorial. The entire November issue is around the subject of congenital infection, with the focus on the most common, serious cause of congenital malformation in Australia – congenital cytomegalovirus. Infection with cytomegalovirus (CMV) causes serious disease in children globally, resulting in congenital infections present in ~2000 Australian newborns every year, of whom most are asymptomatic, with ~450 per annum (pa) affected by hearing loss, mental disability and other illnesses. Some of the key clinical features of congenital infection are outlined here in articles by Wendy van Zuylen, Klaus Hamprecht and Robert George, and the pathogenetic features in Lenore Pereira’s paper. Treatment and vaccination are moving ahead (as discussed in papers from some key Italian groups), although not fast enough for many of us – as parents of children with CMV discuss in two papers here. We also include papers on other causes of congenital infection that are much less common than congenital CMV in Australia. Although these are not related to congenital CMV clinically, with very different medical and epidemiological settings, it is important to put congenital CMV in context, as well as to draw attention to other important causes of congenital infection.

Introduction: Cytomegalovirus (CMV) is a linear, dsDNA virus that is regarded as the prototype of the Betaherpesvirinae subfamily of viruses. It has an established endemic status in certain locations around the globe, and is also reported to be the most prevalently occurring congenital infection in humans. Furthermore, Cytomegalovirus is notorious for being a persistent lifelong pathogen that poses a threat of reactivation as well. Discussion: Congenital cytomegalovirus infection causes numerous ophthalmologic, and neurologic sequelae, and is also known for being the principal reason behind sensorineural hearing loss of non-genetic etiology in neonates. These symptoms, if present, may give rise to a premonition of congenital Cytomegalovirus disease, and so, a diagnosis can be established  through serology, radiology, and  PCR of salivary, urinary, or dried blood spot samples. Timely administration of ganciclovir or valganciclovir has proven to be effective in managing symptomatic cases of congenital CMV. Conclusion: A well-timed delivery of pharmacological and non-pharmacological interventions is necessary to achieve healthy developmental outcomes for the neonate. Moreover, there is still  a need to study the role of antiviral therapy in silent cases since asymptomatic patients are at a risk of developing long-term clinical sequelae as well. Relevance: An estimated 60-90% of women of child-bearing age get infected with Cytomegalovirus, and Congenital CMV disease is reported in 0.2-2.4% of all live births. Therefore, in order to develop effective screening and management protocols, it is vital to educate healthcare professionals regarding the various aspects of this congenital infection.

Abstract Background Arthrogryposis multiplex congenita is the presence of multiple congenital contractures of two or more body parts. Congenital cytomegalovirus (CMV) infection is a rare etiology of arthrogryposis. Case presentation We report a case of intrauterine fetal akinesia and arthrogryposis multiplex congenita delivered at term with subsequent neonatal demise. Placental pathology and autopsy revealed congenital CMV infection. Conclusions Evaluation for potential CMV infection is an important part of the arthrogryposis evaluation which is often missed due to lack of maternal infectious symptoms during pregnancy.

Congenital cytomegalovirus (CMV) infection is the most common congenital infection worldwide and most individuals are eventually exposed to this agent. In developing countries the seroprevalence in women of reproductive age approximates 100%. Cytomegalovirus (CMV) infection has great importance to obstetriciangynecologists and pediatricians. Despite the heavy disease burden, CMV infection is severely under-diagnosed because the majority (approximately 80%) of affected mothers are asymptomatic. The clinical manifestations of congenital CMV infection vary widely, from asymptomatic infection to potentially life-threatening disseminated disease. Prenatal diagnosis of fetal CMV infection can be made by testing amniotic fluid for cytomegalovirus by amniocentesis. Diagnosis of congenital cytomegalovirus infection in neonates should include real-time PCR of saliva, urine, or both, as soon as possible after birth. Antiviral therapy is not routinely recommended for congenital cytomegalovirus infection. Neonates with life-threatening infection and moderately to severely symptomatic congenital cytomegalovirus disease, CNS involvement is considered for immediate treatment that should be initiated within first month of life.

Congenital cytomegalovirus infection (cCMV) is very common, yet the presentation can be varied, making the diagnosis challenging. However, early diagnosis for treatment with medication in symptomatic cases within the first month of life is critical. Hyperbilirubinemia and splenomegaly are less common manifestations at birth and may be overlooked in the setting of other symptoms, especially in a critically ill neonate. We present a case of a term infant with trisomy 21 who presented with isolated hyperbilirubinemia and splenomegaly and was later diagnosed with congenital CMV.

Fetal Infection

A 22-year-old pregnant woman was referred to our fetal medicine unit due to severe fetal growth restriction at 26 weeks of gestation. An extensive detailed ultrasound revealed signs of bilateral periventricular hyperechogenicity, suggesting fetal infection potentially due to cytomegalovirus (CMV). Doppler ultrasound showed a high peak systolic velocity in the middle cerebral artery. Percutaneous umbilical cord blood sampling confirmed fetal CMV infection and severe fetal anaemia. We present this case to highlight the importance of fetal anaemia, which can be fatal regardless of whether it is associated with generalised oedema or hydrops fetalis.

SUMMARYCongenital cytomegalovirus (CMV) infection rates increase with maternal seroprevalence due to transmission from maternal non-primary infection. CMV seroprevalence estimates of pregnant women are needed for planning strategies against congenital CMV transmission. We aimed to determine the age-specific prevalence of serum antibodies for CMV in a representative age-stratified sample of unselected pregnant women from a Brazilian population. A total of 985 pregnant women, aged 12–46 years (median 24 years), were enrolled. Overall CMV seroprevalence was 97% (95% confidence interval 95·8–98·0), with age-specific (years) prevalence as follows: 12–19 (96·3%), 20–24 (97·7%), 25–29 (97·1%), and 30–46 (96·7%). CMV seroprevalence is almost universal (97%) and is found at similar levels in pregnant women of ages ranging from 12 to 46 years. Because high CMV seroprevalence is found even in women of a younger age in this population, this finding suggests that the majority of primary CMV infections occur early, in infancy or childhood. As a consequence, vaccines currently under development to prevent primary infection may not be a solution for the prevention of congenital CMV infection in this population.

Background: Congenital cytomegalovirus infection is currently the leading cause of congenital infection in 0.2-2.2% of live births worldwide leading to variable serious sequalae. The aim of the study was to determine if low birth weight is an indicator of CMV congenital infection evidenced by detecting CMV-DNA in umbilical cord blood at the time of delivery. Methodology: CMV-IgG and IgM antibodies and CMV-DNAemia were assessed in umbilical cord blood of two hundreds newborns, one hundred of whom had birth weight ≤ 2700 gram and/or head circumference ≤ 32 cm. Results: CMV-IgM was not detected, while CMV-IgG was positive in 80-90% of the two hundreds tested newborns. CMV-DNA was detected in four out of the 200 newborns. One of them was over the adopted weight limit (> 2700 gram). Conclusions: CMV-IgM and IgG antibodies assessment was not a potential discriminative test to identify congenitally infected newborns. In addition, low birth weight and small head circumference at birth failed to predict congenital CMV infection. CMV-DNA detection in umbilical cord blood at the time of delivery using real-time PCR of all newborns is recommended as decisive, rapid and non-invasive test.
