Human cytomegalovirus (CMV) is a herpesvirus, a member of the beta-herpesvirus subfamily. Infection with CMV represents a major cause of congenital infection, and also a cause of perinatal infection. We present the case of a 3 months-old sugar with breast milk jaundice and hepatic cytolysis, in our evidence from one month. At the age of 6 weeks, at the second evaluation, the laboratory tests showed a mild increase of lymphocytes and monocytes, minimum hepatic cytolysis and positive CMV immunoglobulin M (IgM) assays. Our decision was to follow up the case, without antiviral therapy, because the acute CMV infection was asymptomatic. Therefore, the hepatic cytolysis may precede the presence of CMV in blood, because the immune mediated response to CMV involve specific antibodies type IgM few weeks after the moment of infection.

ObjectiveHuman cytomegalovirus (CMV) is the most widespread agent of congenital infection in humans and is still a challenging issue. Despite lower rates of vertical transmission being associated with recurrent infection when compared with primary infection, the first still represents the majority of congenital infections worldwide. Based on data from active reporting, we explored the influence of maternal primary/non-primary infection both on the presentation and outcome of congenital CMV infection in early childhood.DesignInfants with positive viruria during the first 3 weeks of life were reported through the Portuguese Paediatric Surveillance Unit.PatientsInfants born between 2006 and 2011 with confirmed congenital CMV infection.MethodsMaternal infection was considered primary if CMV IgG seroconversion occurred during pregnancy or low avidity IgG was documented; it was considered non-primary if positive IgG was documented before pregnancy or high avidity CMV IgG was present early in pregnancy. Follow-up questionnaires were sent up to 6 years of age.ResultsForty confirmed cases of congenital CMV infection were reported (6.6:105 live births, 95% CI 4.81 to 8.92); 22 out of 40 were asymptomatic. The odds for non-primary maternal infection if the offspring was symptomatic at birth were 6.2 (95% CI 1.2 to 32.27).ConclusionThe reported number of confirmed cases of congenital CMV infection was much lower than expected. Under-reporting and missed diagnosis were considered possible reasons. Non-primary maternal infections were associated with symptomatic congenital CMV infection in the offspring. Maternal recurrent infections can have a significant impact on the total number of symptomatic infections in Portugal.

Cytomegalovirus (CMV) is the commonest cause of congenital infection (cCMVi) and particularly so among infants born to HIV-infected women. Studies of cCMVi pathogenesis are complicated by the presence of multiple infecting maternal CMV strains, especially in HIV-positive women, and the large, recombinant CMV genome. Using newly developed tools to reconstruct CMV haplotypes, we demonstrate anatomic CMV compartmentalization in five HIV-infected mothers and identify the possibility of congenitally transmitted genotypes in three of their infants. A single CMV strain was transmitted in each congenitally infected case, and all were closely related to those that predominate in the cognate maternal cervix. Compared to non-transmitted strains, these congenitally transmitted CMV strains showed statistically significant similarities in 19 genes associated with tissue-tropism and immunomodulation. In all infants, incident superinfections with distinct strains from breast milk were captured during follow-up. The results represent potentially important new insights into the virologic determinants of early CMV infection.

Abstract Objective The aims of this study were to evaluate the clinical characteristics, laboratory data, and treatment of the cytomegalovirus (CMV)-associated thrombocytopenia in infants aged younger than 12 months and to investigate the possible relationship between genotypes of glycoprotein B (gB) and glycoprotein H (gH) and CMV-associated thrombocytopenia. Study Design Infants with positive identification of cytomegalovirus (CMV) and thrombocytopenia, being treated at Hubei Maternal and Child Health Hospital from January 2015 to June 2019 were included. Genotype of gB and gH analysis were done by nested polymerase chain reaction (nPCR) and restrictions length polymorphism. Results The prevalence of CMV congenital, perinatal, and postnatal infection were 1.4% (76/5428), 29.1% (378/1301), and 41.8% (243/581), respectively. A total of 29 immunocompetent patients with CMV-associated thrombocytopenia were analyzed, including 7 (9.2%, 7/76) congenital infections, 14 (3.7%, 14/378) perinatal infections, and 8 (3.3%, 8/243) postnatal infections. Platelet count at diagnosis <20 × 109/L was the common hematologic finding of CMV-associated thrombocytopenia in perinatal infection (1/7 congenital infection vs. 10/14 perinatal infection vs. 3/8 postnatal infection, Chi-square (χ2) = 6.616, p = 0.037). Notably, significantly higher frequency of hepatobiliary symptoms was found in congenital and perinatal infections groups (4/7 congenital infection vs. 10/14 perinatal infection vs. 1/8 postnatal infection, χ2 = 7.188, p = 0.027). Intravenous immunoglobulin was prescribed for 24 (82.8%, 24/29) patients, and antiviral agents were prescribed for 9 (31.0%, 9/29) patients. The most prevalent genotypes of CMV in the study were gB1 (60.7%, 17/28) and gH2 (57.1%, 16/28). Conclusion There was a substantial percentage of symptomatic CMV infection in patients aged younger than 12 months. Thrombocytopenia is one of the common clinical manifestations in congenital CMV infection. The gB1 genotype had more virulence in infants with acquired CMV infection. There might be an association between gH2 genotype of CMV and CMV-associated thrombocytopenia.

In Pregnancy

Cytomegalovirus (CMV) infection is of great importance to obstetrician-gynecologists because maternal infection is relatively common and can result in severe injury to the fetus. The greatest risk to the fetus occurs when the mother develops a primary CMV infection in the first trimester. Forty to 50% of infants delivered to mothers with primary CMV infections will have congenital infections. Of these neonates, 5–18% will be overtly symptomatic at birth. Approximately 30% of severely infected infants die, and 80% have severe neurologic morbidity. Eighty-five to 90% of infants will be asymptomatic, and 10–15% of these babies subsequently have sequelae such as visual and auditory defects. If the mother develops a recurrent or reactivated CMV infection during pregnancy, the risk of a severe congenital infection is very low. Perinatal infection, as opposed to congenital infection, may result from exposure to the virus during delivery or lactation and rarely leads to serious sequelae. Antimicrobial therapy and immunotherapy for CMV are, at present, unsatisfactory. Therefore, all patients, pregnant women in particular, must be educated about preventive measures.

First Year Of Life

We reviewed the files of 110 women with Toxoplasmaseroconversion during pregnancy. Prenatal diagnosis was attempted for 94 women by amniotic fluid sampling. Toxoplasma gondii was detected by PCR, with or without tissue culture and mouse inoculation. The early neonatal diagnostic procedure included placental testing by PCR and/or mouse inoculation, cord blood serological testing, and comparison of maternal and newborn antibodies by Western blotting (WB). Serological follow-up of the infants was conducted during the first year of life or until the diagnosis of congenital toxoplasmosis (CT) could be ruled out. Congenital infection was diagnosed in 27 individuals (20 live births) in the prenatal and/or neonatal period. The sensitivity and specificity of prenatal diagnosis were 81 and 100%, respectively. Placental examination was positive for 66.7% of individuals with CT and was always negative for neonates without CT. Cord blood serology detected immunoglobulin M (IgM) and/or IgA in 80% of infected newborns, with respective specificities of 91.2 and 87.7%. By WB we detected bands on IgG and IgM blots recognized by the newborn serum but not by the maternal serum (neosynthesized IgG and/or IgM) for 88.2% of infected infants within the first 2 months of life with a specificity of 100%. Early postnatal diagnosis was negative for 2 of the 20 neonates with CT. Both of these newborns had a negative prenatal diagnosis and were asymptomatic, suggesting a very low parasite load. In conclusion, despite the use of advanced methods, some cases of congenital toxoplasmosis cannot be detected early, which underlines the importance of careful follow-up of newborns who are at risk.

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.

Toxoplasma Gondii Infection

From 1992 to 1994 a screening program for detection of specific Toxoplasma gondii antibodies involving 35,940 pregnant women was conducted in Norway. For women with serological evidence of primary T. gondii infection, amniocentesis and antiparasitic treatment were offered. The amniotic fluid was examined for T. gondii by PCR and mouse inoculation to detect fetal infection. Infants of infected mothers had clinical and serological follow-up for at least 1 year to detect congenital infection. Of the women 10.9% were infected before the onset of pregnancy. Forty-seven women (0.17% among previously noninfected women) showed evidence of primary infection during pregnancy. The highest incidence was detected (i) among foreign women (0.60%), (ii) in the capital city of Oslo (0.46%), and (iii) in the first trimester (0.29%). Congenital infection was detected in 11 infants, giving a transmission rate of 23% overall, 13% in the first trimester, 29% in the second, and 50% in the third. During the 1-year follow-up period only one infant, born to an untreated mother, was found to be clinically affected (unilateral chorioretinitis and loss of vision). At the beginning of pregnancy 0.6% of the previously uninfected women were falsely identified as positive by the Platelia Toxo-IgM test, the percentage increasing to 1.3% at the end of pregnancy. Of the women infected prior to pregnancy 6.8% had persisting specific immunoglobulin M (IgM). A positive specific-IgM result had a low predictive value for identifying primaryT. gondii infection.

Seventy primary molar teeth, carious exposed, symptom free, without any sign of root resorption in children aged from 3 to 6 years (main age 4.3yr) were treated with conventional pulpotomy procedures. Ferric sulfate 15.5% solution (applied for 15 second for 35 teeth) and formocresol solution (five minute procedure of Buckley's formula for next 35 teeth) have been used as pulpotomy agents. In both groups, pulp stumps were covered with zinc-oxide eugenol paste. Permanent restorations were stainless steel crowns. Clinical check up was every three-months and radiographic follow-up time was six and twenty months after treatment. Our results within this period revealed 100% clinical success rate in both groups. Radiographic success rate was in both groups 97.2%, while in 2.8% cases has shown internal root resorption. On the basis of these results, we can recommend ferric sulfate as a pulpotomy agent in primary teeth in substitution for formocresol at the moment.

<b><i>Objective:</i></b> In 2011, the Israeli Ministry of Health (MOH) published standard guidelines for the follow-up of pregnant women infected by CMV, recommending that amniocentesis be performed in cases of maternal serum viral seroconversion or abnormal sonographic findings suggestive of CMV, in order to prove fetal infection before electing for pregnancy termination. <b><i>Methods:</i></b> A retrospective cohort study was performed, describing 448 pregnant women from 2006 to 2017. We collected data from all women that elected to continue their pregnancies after seroconversion and also of those who chose to undergo pregnancy termination. Subsequently, a telephone survey was then conducted to record outcomes of the newborns of women with CMV seroconversion during pregnancy. <b><i>Results:</i></b> 325 (73%) women chose to continue their pregnancy, while 123 (27%) opted for termination of pregnancy. We found that pregnancy termination due to CMV infection was reduced by 7%, from 72 cases (32%) to 51 cases (25%) after the implementation of the MOH guidelines in 2011. In addition, 182/305 (60%) of women responded to our telephone questionnaire regarding newborn outcomes. Of these women, 45/305 (14%) reported complications, and no correlation was found between the prenatal findings and postnatal outcome among those who have responded to our survey. <b><i>Conclusion:</i></b> Implementation of the new MOH guidelines has reduced the rate of pregnancy termination, without increasing the rate of neonatal complications in Israel with a similar outcome of complication rate as reported in the literature.
