Abstract Background: Congenital CMV infection is the first worldwide cause of congenital viral infection and a major cause of sensorineural hearing loss and mental retardation. As systematic screening of pregnant women and newborns is still debated in many countries, this systematic review aims to provide the state of the art on current practices concerning management of congenital CMV infection.Methods: We will perform electronically searches on MEDLINE, EMBASE, Cochrane Library (CENTRAL), ClinicalTrials.gov, Web of Science and hand searches in grey literature. Interventions regarding biological, imaging, and therapeutic management of infected pregnant women, fetuses and neonates/children (from birth to 6 years old) will be studied in this systematic review. Study screening will be performed in duplicate by two independent reviewers and risk of bias will be evaluated with the ROBINS-I tool. Discussion: This review will provide the state of the art of current management of congenital CMV infection in pregnant women, fetuses, neonates and children until 6 years old, in order to have an overview of current practices of congenital CMV infection.Systematic review registration: PROSPERO CRD42019124342

Introduction Congenital CMV infection is the first worldwide cause of congenital viral infection but systematic screening of pregnant women and newborns for CMV is still debated in many countries. Objectives This systematic review aims to provide the state of the art on current practices concerning management of maternal and congenital CMV infection during pregnancy, after maternal primary infection (PI) in first trimester of pregnancy. Data sources Electronically searches on databases and hand searches in grey literature. Study eligibility criteria and participants Primary outcome was listing biological, imaging, and therapeutic management interventions in two distinct populations: population 1 are pregnant women with PI, before or without amniocentesis; population 2 are pregnant women with congenitally infected fetuses (after positive amniocentesis). Secondary outcome was pregnancy outcome in population 2. Results Out of 4,134 studies identified, a total of 31 studies were analyzed, with 3,325 pregnant women in population 1 and 1,021 pregnant women in population 2, from 7 countries (Belgium, France, Germany, Israel, Italy, Spain and USA). In population 1, ultrasound (US) examination frequency was 0.75/month, amniocentesis in 82% cases, maternal viremia in 14% and preventive treatment with hyperimmune globulins (HIG) or valaciclovir in respectively 14% and 4% women. In population 2, US examination frequency was 1.5/month, magnetic resonance imaging (MRI) in 44% cases at 32 weeks gestation (WG), fetal blood sampling (FBS) in 24% at 28 WG, and curative treatment with HIG or valaciclovir in respectively 9% and 8% patients. Conclusions This systematic review illustrates management of maternal and congenital CMV during pregnancy in published and non-published literature, in absence of international consensus.

SUMMARYA prospective study identified 785 pregnant women who had been shown to possess complement fixing antibodies against cytomegalovirus (CMV) during a previous pregnancy. As these women were thus known to have been immune prior to their subsequent conception, their neonates were examined for evidence of congenital CMV infection. Specimens were obtained from 725(92%) of the neonatcs and congenital infection was found in only one (0·14%). The elder sister of the infected child was also shown, by retrospective testing of her stored cord serum for specific IgM antibodies, to have been infected in utero. Thus, one woman was identified who had delivered consecutive siblings congenitally infected with CMV. We conclude that some women have a propensity for intra-uterine transmission of CMV, despite being immune prior to conception, and speculate that such women may have acquired their infections perinatally.

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.

Abstract Objectives To introduce a first-line noninvasive antenatal management of maternal cytomegalovirus (CMV) primary infection based on ultrasound (US) and magnetic resonance imaging (MRI). Amniocentesis (AC) is used as a second-line tool in cases of abnormalities compatible with fetal CMV infection on US and/or MRI screening. Methods Between January 2011 and October 2018, pregnant women referred with a CMV primary infection on antibody screening were followed up by monthly US scans and a brain MRI at approximately 32 weeks. In cases with US and/or MRI abnormalities compatible with congenital CMV infection, AC was performed to confirm the diagnosis. Results Ninety pregnant women with a primary CMV infection were included (89 singleton and one twin pregnancy). The first-line screening by US and/or MRI was normal for 72 of 91 fetuses (79%). At birth, 19 of these 72 neonates (26%) had a positive urine sample for CMV but were asymptomatic. US and/or MRI abnormalities were identified in 19 fetuses (21%). AC confirmed a fetal CMV infection in 16 fetuses (84%); 12 pregnancies were terminated, and four were continued, with three symptomatic neonates at birth and one poor neurodevelopmental outcome at postnatal follow-up. Conclusions First-line noninvasive management of maternal CMV primary infection based on serial US scans and brain MRI can be offered to identify fetuses with severe symptomatic congenital CMV infection and reduce the number of ACs without compromising the fetal outcome.

Congenital Cytomegalovirus (CMV) infection is one of major public health concerns and one of the most frequent congenital infections worldwide. Congenital CMV infection is under-diagnosed in the majority of asymptomatic pregnant women due to its self-limited non-specific symptoms and unimplemented screening program. It also can go undetected at birth because in affected newborns are often asymptomatic; however, they manifest serious morbidities later in life. Primary CMV infections are associated with the highest in-utero transmission with estimated rates of 30–35% . Transmission occurs less frequently in secondary maternal infections at approximately 1.1–1.7%. There are growing evidences that early treatment with the antiviral therapy in newborns with congenital CMV infection can reduce sensorineural hearing loss (SNHL) and the substantial long-term neurodevelopmental disabilities. There is increased interest in establishing a prophylactic CMV vaccines that can protect seronegative mothers from primary infection and also to augment the immune response in seropositive women in order to prevent reactivation or re-infection. Saliva PCR assay can be used to screen newborns within the first 3 weeks of age instead of Dried blood spots (DBS), liquid-saliva PCR assay sensitivity is “100%” higher than DBS sensitivity “35%-100%" as not all infants have detectable viraemia at birth. Suggestive strategies to reduce the burden of congenital CMV disease and ensure better outcomes are; establishing a screening programme for pregnant mothers, developing prophylactic CMV vaccines, early therapeutic intervention in pregnant women and newborns and to replace DBS with Saliva PCR assay in screening newborns.

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.

Human cytomegalovirus (CMV) is the leading non-genetic cause of fetal malformation in developed countries. Congenital CMV infection can cause serious clinical sequelae, and in severe cases result in fetal or neonatal death. Despite the clinical and social importance of congenital CMV there is currently no standardised management strategy to prevent or treat maternal/fetal CMV infection during pregnancy and no evidence-based therapeutic for prenatally diagnosed CMV infection or disease. For pregnant women with a primary CMV infection during pregnancy, standard medical practise remains to offer no treatment at all or the option to terminate pregnancy. If intervention is requested, pregnant women may be offered a narrow range of medical therapies with limited evidence for efficacy and some with high risks of toxicity. However, there are several experimental and novel anti-CMV therapeutics currently being investigated that may provide a safe and effective therapeutic for use during pregnancy to prevent both fetal infection and reduce the risk of congenital CMV disease developing in the fetus once infected in utero.

Pregnant women [60]with and without serological evidence of active cytomegalovirus [CMV]infection were followed until delivery to detect the incidence and types of overt congenital CMV infection in neonates in Mosul, Iraq. Infection was diagnosed by the detection of CMV-IgM, using ELISA. CMV-IgM was detected in cord blood samples of six [10%]overtly sick infants [with different congenital malformations]born to mothers with active CMV infection. Central nervous system abnormalities were detected in all six cases [two with microcephaly and four with hydrocephaly]. Congenital CMV infection should be suspected in infants born with congenital malformations, especially those of the central nervous system. The detection of a significant number of hydrocephalus cases in our study is notable
