Abstract Cytomegalovirus (CMV) is the most common congenital infection and infectious cause of fetal anomaly and neurologic injury. However, treatment strategies for congenital CMV (cCMV) infection during pregnancy remain elusive. We report a case of hydrops fetalis secondary to cCMV infection with minimal sequelae after maternal and subsequent neonatal treatment with valganciclovir.

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.

Cytomegalovirus (CMV) is a frequent cause of congenital infection in humans in all regions of the world. In contrast to most congenital viral infections, congenital CMV infection and disease have been consistently demonstrated in populations with a high seroprevalence. Three hundred pregnant women were studied prospectively in their 1st, 2nd and 3rd trimester to determine the seroprevalence and seroconversion of CMV in pregnancy. After birth, babies were also tested for anti CMV IgM to determine the rate of birth prevalence. Anti CMV IgG and IgM tests were performed by chemiluminescence methods. All 300 (100%) pregnant women were anti CMV IgG positive and 180 (60%) were subsequently anti CMV IgM positive during different trimesters of pregnancy. Birth prevalence of CMV IgM antibody was 1.3% among babies of anti CMV IgM positive mothers whereas none in CMV IgM negative mothers (OR 1.01, 95% CI .996-1.027).It may be concluded that CMV IgG seroprevalence is high among Bangladeshi pregnant women and the rate of CMV reactivation is also high during pregnancy. Despite protection by maternal immunity a certain percent of babies acquire congenital CMV infection.

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.

AbstractHuman cytomegalovirus (HCMV) is the most common congenital infection and a known cause of microcephaly, sensorineural hearing loss, and cognitive impairment among newborns worldwide. Natural maternal HCMV immunity reduces the incidence of congenital infection, but does not prevent the disease altogether. We employed a nonhuman primate model of congenital CMV infection to investigate the ability of preexisting antibodies to protect against placental CMV transmission. Pregnant, CD4+ T cell-depleted, rhesus CMV (RhCMV)-seronegative rhesus monkeys were treated with either standardly-produced hyperimmune globulin (HIG) from RhCMV-seropositive macaques or dose-optimized, potently RhCMV-neutralizing HIG prior to intravenous challenge with an RhCMV swarm. HIG passive infusion provided complete protection against fetal loss in both groups, and the potently-neutralizing HIG additionally inhibited placental transmission of RhCMV. Our findings suggest that antibody alone at the time of primary infection can prevent congenital CMV and therefore could be a primary target of vaccines to eliminate this neonatal 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.

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.

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.
