Abstract
Congenitally acquired cytomegalovirus (CMV) infection is the most prevalent congenital infection worldwide and the most frequent cause of acquired sensorineural hearing loss. The burden of the disease is even more important in premature and very low birth weight infants. However, few data exist on the treatment with intravenous ganciclovir and oral valganciclovir in this vulnerable population. We report the case of twins congenitally infected with CMV and born prematurely at 27 weeks' gestation. Treatment regimens were initially individualized for their prematurity and renal function, and then adjusted with therapeutic drug monitoring (TDM) to adapt to their continuously evolving physiologic maturation. As infants were aging, the plasmatic half-life of ganciclovir slowly decreased to term infant values around 10 weeks of chronological age, or 37 weeks of postmenstrual age. Results for blood polymerase chain reaction tests became negative and long-term follow-ups were satisfactory in both twins. The limited data for infants born before 32 weeks of gestation or at less than 1200 g and evolution of ganciclovir pharmacokinetic parameters justify the use of TDM in these settings.

Abstract
Cytomegalovirus infection occurs commonly during infancy. Postnatal infection in term infants is usually asymptomatic; however, infection in preterm infants can be associated with clinical manifestations during the neonatal period. Nevertheless, few studies to assess the frequency of cytomegalovirus infection in preterm infants have been performed outside of high-income countries. We analyzed the incidence of congenital and postnatal cytomegalovirus infection in a cohort of preterm infants. Cytomegalovirus infection was detected during the neonatal period in four of 178 infants; in three of them the virus was detected during the first three weeks of life and, therefore, congenital infection was confirmed (1.7% incidence). Postnatal infection was detected in 44 (36.4%) of 121 infants who were assessed after discharge from the neonatal intensive care unit. Cytomegalovirus infection was significantly associated to duration of breast feeding. In addition, we characterized cytomegalovirus strains detected in infants together with sequences available at GenBank, based on sequences of the UL18 gene. Cytomegalovirus UL18-sequences clustered in five distinct clades (A-E), and sequences obtained from infants in our study were distributed in four of the five clades; 44.4% of these sequences were included in clade E. Breastfeeding duration was shorter in average (5.6 months) in infants with sequences in clade E compared to infants with sequences in the other three clades (8.2 months; P=0.07). In conclusion, we provide information regarding the high incidence of cytomegalovirus infection in preterm infants. Further studies are warranted to assess if cytomegalovirus strain characteristics are associated with the risk of infection acquisition during infancy. This article is protected by copyright.

Abstract
OBJECTIVES The aim of this study was to assess the seroprevalence and associated factors of cytomegalovirus (CMV) among pregnant women in Southern Ethiopia. DESIGN Cross-sectional study. SETTING The study was conducted in Hawassa University comprehensive and specialised hospital. Hawassa, Southern Ethiopia. PARTICIPANTS A total of 600 consecutive pregnant women attending the delivery ward were recruited for the study from August to October 2020. OUTCOME MEASURES The study assessed the rate of maternal anti-CMV IgG and IgM antibodies. The association of obstetric history, sociodemographic and behavioural characteristics with seropositivity of CMV was also evaluated based on the collected data using structured questioners. RESULTS Seropositivity for CMV IgM antibodies was 8.2% (49/600) (95% CI 6% to 10.5%), whereas the CMV IgG was 88.7% (532/600), (95% CI 89.5% to 94.0%). Seroprevalence of CMV IgM was higher in women of older age, currently unmarried, having nursery schooled children and with any of the detected curable sexually transmitted infections, while seroprevalence of CMV IgG was significantly associated only with women having nursery schooled children. Seroprevalence was not significantly associated with previous adverse pregnancy outcome, gravidity, being a child daycare occupant mother and newborn birth weight. CONCLUSION In the present study, we identified a high rate of CMV IgM and CMV IgG seroprevalence among pregnant women in Southern Ethiopia. Given that there is no existing CMV diagnosis, special attention should be designed to pregnant women in parallel to the existing antenatal care facility. Besides, training healthcare professionals will support awareness conception among pregnant women concerning the sequels of CMV infection during pregnancy.

Abstract
Toll-like receptors (TLRs) recognize pathogen-associated molecular patterns and are essential components of the host’s innate immune response. The aim of this study was to determine the TLR9 genotype frequency and investigate the association between TLR9 polymorphisms and cytomegalovirus (CMV) DNAemia in human immunodeficiency virus (HIV)/CMV co-infected patients. A total of 205 HIV/CMV co-infected adults were screened for the presence of the four TLR9 polymorphisms (−1237T/C, −1486T/C, 1174G/A, and 2848C/T) by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Mutation presented in at least one allele of the TLR9 2848C/T single nucleotide polymorphism (SNP) was associated with the occurrence of CMV DNAemia among HIV-infected patients with CMV co-infection (p = 0.004). The level of CMV DNA was higher in patients who were homozygous recessive or heterozygous for the 2848C/T polymorphism compared with those who had a wild-type genotype for this polymorphism (p = 0.005). Mutation detected in at least one allele of this SNP was also associated with a lower interferon type β (IFN-β) concentration (p = 0.048), while no relationships between TLR9 −1237T/C, −1486T/C, and 1174G/A SNPs and CMV DNAemia were observed. Our findings suggest that the mutation present in at least one allele of the TLR9 2848C/T SNP may be associated with the active CMV infection in HIV/CMV co-infected subjects.

Abstract
Background: The aims of this study were to evaluate the incidence of congenital cytomegalovirus (CMV) in term and near-term infants who fail hearing screen (target screening), the incidence of congenital CMV infections in infants born before 33 weeks of gestation (universal screening) and the incidence of infants who need pharmacologic treatment for congenital CMV associated sensorineural hearing loss (SNHL).Methods: This was a retrospective cohort study that assessed two groups of infants born between 2014 and 2017. The first group consisted of infants born between 33 and 42 weeks gestation and the second group, of infants born before 33 weeks gestation. Targeted CMV screening was performed in the first group who either failed neonatal hearing screen or were growth retarded. Universal screen was performed in the second group of infants. CMV DNA was tested in urine samples using real time PCR soon after birth.Results: In the first group, 2078 infants were assessed, 19 (0.9%) were found to be CMV positive and in 9 (42%) valganciclovir treatment was initiated. In the second group, out of 549 urine samples/infants, none was positive for CMV DNA soon after birth.Conclusions: A joint strategy of targeted CMV screening in infants who fail hearing screen test with universal screen of premature infants can select infants at risk of hearing impairment due to congenital CMV soon after birth, allows for timely initiation of treatment and prevents dilemmas regarding congenital CMV diagnosis in infants who fail hearing screen in a later age until universal screen will be widely adopted.

Abstract
BACKGROUND Congenital cytomegalovirus (CMV) infection is the leading cause of neurologic disabilities and sensorineural hearing loss in children. However, in Taiwan, there is limited information on the genotypic diversity and prevalence of perinatal CMV infection in both mothers and neonates. The aim of this study was to screen samples from both mothers and umbilical cord blood for CMV at the time of delivery and to determine the CMV genotypic distribution. METHODS Between June 2012 and July 2015, residual maternal and umbilical cord blood samples were collected from consenting participants admitted to the Chang Bing Show Chwan Memorial Hospital in central Taiwan. The blood samples were screened for CMV DNA using real-time PCR assay, and the genotypic classification of the CMV UL55, UL144, and US28 genes was determined by sequencing and phylogenetic analysis. RESULTS A total of 1282 mother-neonate paired samples were enrolled in the study, 95.3% of whom were Taiwanese. CMV DNA was detectable in 6.2% of the maternal blood samples, with a significantly higher rate noted in non-Taiwanese mothers (11.7%,p=0.027). For the 1,282 umbilical cord blood samples, CMV DNA was detectable in 5.3% of the samples. The presence of CMV DNA in maternal blood was positively associated with the presence of CMV DNA in umbilical cord blood (p=0.01). In addition, the UL55, UL144, and US28 genotypic distribution was similar between mothers and neonates. CONCLUSION The prevalence of CMV DNAemia in childbearing mothers and neonates is similar and their genotypic distribution implies potential CMV infection during pregnancy.

Abstract
Although highly heritable, adult height is also associated with numerous environmental factors, including exposure to infection. Particularly in developing regions of the world, infection burden appears to slow growth during childhood. Using a large database representative of the US population, we examined associations between adult height and leg length and an infection-burden index based on past exposure to Toxocara species, Toxoplasmosis gondii, cytomegalovirus, hepatitis A, hepatitis B, hepatitis C, herpes simplex virus 1, and herpes simplex virus 2. In models controlled for age, sex, educational attainment, socioeconomic status, and race-ethnicity, we found that the infection-burden index predicted height (β=-0.10 [95% CI: -0.15, -0.05], p .001<0.001) but not leg length (β=-0.04 [95% CI: -0.12, 0.04], p=0.357). Both sex and race-ethnicity moderated this association. In addition, exposures to Toxocara species, cytomegalovirus, and hepatitis A were each individually associated with reduced height and reduced leg length. While associations between growth and infection have been found principally in children in developing regions of the world, our findings suggest that the effects of infection on height may persist into adulthood even in developed nations.
