Prompt and accurate laboratory testing of women before or during antenatal days is necessary for detecting humoral immunological responses against cytomegalovirus (CMV) infection and assessing risk of congenital transmission. CMV is the most common viral etiology with the greatest propensity to induce neonatal pathologies. Most healthcare facilities in developing countries rely solely on anti-C...

BACKGROUND Interpretation of positive cytomegalovirus (CMV) immunoglobulin M (IgM) in the first trimester of pregnancy is ill-defined. We aimed to quantify the risk of fetal transmission in women with positive CMV IgM in the first trimester. METHODS A retrospective cohort of women (2009-2011) was tested for CMV immunoglobulin G (IgG) and IgM before 14 weeks of gestation. IgG avidity was teste...

Congenital cytomegalovirus (CMV) infection is a leading cause of hearing, cognitive, and motor disability in children for which medical science has yet to provide prevention or cure. Although vaccines aimed at prevention of congenital infection are being developed, there are significant challenges to be overcome and it could easily be a decade or longer before a CMV vaccine is licensed for prev...

BACKGROUND In this study, we aimed to determine the provincial population-based seroprevalence in pregnant women and to further explore the association of maternal CMV infection status and adverse pregnancy/neonatal/growth outcomes in Jiangsu, China. METHODS In this case-control study, the sera from 527 pregnant women with adverse pregnancy/neonatal outcomes and 496 mothers of healthy infants...

background : cytomegalovirus (cmv) is the most common cause of congenital infection, with increased morbidity and mortality at birth. the risk of intrauterine infection largely depends on the time of maternal infection during pregnancy. currently, no national screening test for cmv infection is available during pregnancy in iran. the aim of this study was to determine the seroprevalence of cmv ...

INTRODUCTION Transmission of cytomegalovirus (CMV) via breast milk can lead to severe acute illness in very low-birth-weight (VLBW) preterm infants. Although the majority of CMV-seropositive women shed CMV in milk, symptomatic postnatal infection of VLBW infants occurs infrequently, suggesting that virologic or immunologic factors in milk may be associated with the risk and severity of postnata...

No single diagnostic test for cytomegalovirus (CMV) infection is currently available for pregnant women at all stages of gestation. Improved accuracy in estimating the timing of primary infections can be used to identify women at higher risk of giving birth to congenitally infected infants. A diagnostic algorithm utilizing immunoglobulin G (IgG), IgM, and IgG avidity was used to prospectively s...

BACKGROUND Some evidence has shown a relationship between human cytomegalovirus (CMV) infection and pregnancy loss. However, whether recurrent or latent CMV infection or altered immune response to CMV is related to recurrent pregnancy loss (RPL) is unclear. We evaluated CMV infection and avidity of antibodies to CMV in women with RPL. MATERIALS AND METHODS This case-control study was conducte...

Fetal damage following cytomegalovirus (CMV) intrauterine infection is mostly linked to primary infection. To differentiate primary infection from nonprimary infection, immunoglobulin M (IgM) tests are not reliable enough, and measurement of the IgG avidity appears to be the method that is the most widely used at present. In the present study the performance of the Vidas (bioMérieux) avidity as...

Dear Editor, The recent report by Kamel et al. [1] on primary cytomegalovirus infection in pregnant women is very interesting. The authors noted that ‘women who were IgM positive had no primary CMV infection in the index pregnancy as evidenced by the high CMV IgG avidity testing’ [1] . In fact, the usefulness of the IgG avidity test was previously reported by Seo et al. [2] , who noted that thi...
