Post-traumatic stress in pregnant women with primary cytomegalovirus infection and risk of congenital infection in newborns

The Involvement of Neonatal Intensive Care Unit and Other Perinatal Factors in Postpartum PTSD After Cesarean Section

BACKGROUND

The experience of a neonate hospitalised in the Neonatal Intensive Care Unit (NICU) is an understandably traumatic experience for the parents, especially, for the mothers of neonates. This mental distress resulting from preterm birth and/or NICU hospitalisation can be understood as post-traumatic symptomatology, according to the Diagnostic and Statistical Manual-5 version. The aim of this study is to investigate the impact of the admission of a neonate to the NICU (from any reason) on the development of postpartum post-traumatic stress disorder (PTSD) in a sample of women after cesarean sections.

MATERIAL AND METHODS

A total of 469 women who gave birth with cesarean section from July 2019 to June 2020 participated in this study, from the original sample of 490 women who consented to participate. Data were obtained from the researcher's socio-demographic questionnaire, the past traumatic Life Events Checklist, the perinatal stressor Criterion A, and the Post-Traumatic Stress Checklist from the Diagnostic and Statistical Manual-5 version.

RESULTS

A percentage of 46.64% of sample experienced postpartum PTSD. Factors associated with PTSD were placenta previa type4, abruption, bleeding (β = .07, p = .049), premature contractions (β = .08, p = .039), heavy medical history or previous gynecological history and preeclampsia (β = .08, p = .034), abnormal heart rate, premature rupture of membrane, premature contractions, infections (β = .14, p = .004), life of child in danger (β = .12, p = .025), complications involving child (β = .15, p = .002), complications involving both (child and mother) (β = .12, p = .011), traumatic cesarean section (β = .041, p < .001) and prematurity (β = .12, p = .022).

CONCLUSIONS

Additional measures must be taken for mothers of children who have been admitted to the NICU with psychological support interventions and reassessment of their mental state.

A systematic literature review on the humanistic burden of cytomegalovirus

OBJECTIVE

Cytomegalovirus (CMV) infection is typically asymptomatic in healthy individuals; however, certain populations are vulnerable to infection and may develop serious sequelae. CMV infection may also have a broad impact on humanistic outcomes, including patient health status and quality of life (QoL). We conducted a systematic literature review (SLR) to describe the global humanistic burden of CMV and congenital CMV (cCMV) infections across all age groups.

METHODS

Medline, Embase, and LILACS were searched to identify studies on humanistic outcomes following CMV infection, including health status/QoL and any outcomes in domains such as auditory, cognitive ability, developmental status, intelligence, language, memory, mental health, motor performance, social communication, speech, and vocabulary. The SLR included articles published from 2000-2020 and focused geographically on Australia, Europe, Israel, Japan, Latin America, and North America.

RESULTS

Sixty-three studies met the inclusion criteria. In general, individuals with symptomatic cCMV infection experience a greater burden of disease and more substantial impact on QoL versus those with asymptomatic cCMV infection. Children with hearing loss due to cCMV infection, both symptomatic and asymptomatic, showed improved auditory outcomes following cochlear implantation. Newborns, infants, and children with cCMV infections had worse cognitive outcomes in psychological development, sequential and simultaneous processing, phonological working memory, and attention control versus age-matched controls without cCMV infection. CMV infection was also associated with cognitive decline in elderly populations.

CONCLUSIONS

CMV infection can have substantial, lifelong, heterogenous impacts on humanistic outcomes, including health status and QoL, which should be considered when developing and implementing treatment and prevention strategies.

Quality of life, depressive symptoms, anxiety, and sexual function in mothers of neonates with congenital syphilis in the Northeast Brazil: A cohort study

Background

Congenital syphilis is an important public health problem in low- and middle-income countries. Poor neonatal health outcomes associated with the disease may lead to maternal psychological distress and feelings of helplessness. This study aimed to evaluate the quality of life, anxiety levels, depressive symptoms, and sexual function in mothers of neonates with congenital syphilis in the Northeast of Brazil.

Methods

This cohort study compared patient-centered outcomes between mothers of neonates with congenital syphilis and mothers of healthy neonates during the first three months of the postpartum period. The study was conducted in Sergipe state, Northeast Brazil, a region with one of the highest rates of congenital syphilis (14·1 cases per 1000 live births). Quality of life, depressive symptoms, anxiety levels, and sexual function were evaluated by using the World Health Organization Quality of Live - shortened version (WHOQoL-BREF) instrument, Beck Depression Inventory, Spielberger State-Trait Anxiety Inventory, and Female Sexual Function Index, respectively. Unadjusted differences between groups were anayzed by using the Mann-Whitney test. Glass's delta with 95% confidence interval (CI) was used to measure the effect size.

Findings

Sixty-three women were included in each group. During the in-hospital stay, mothers of neonates with congenital syphilis had lower scores for overall quality of life (p < 0·001; large effect size: -0·559 [95% CI -0·683 to -0·405]) and higher levels of anxiety (p < 0·001; large effect size: 0·558 [95% CI 0·403 to 0·681]) and depressive symptoms (p < 0·001; large effect size: 0·561 [95% CI 0·407 to 0·684]) than mothers of healthy neonates. Three months after childbirth, we found persistent depressive symptoms (p = 0·021; small effect size: 0·239 [95% CI 0·041 to 0·419]) and low overall sexual function (p = 0·041; small effect size: -0·211 [95% CI -0·394 to -0·012]) among mothers of neonates with congenital syphilis compared to the control group.

Interpretation

Mothers of neonates with congenital syphilis present poorer quality of life, mental health, and sexual function compared to mothers of healthy neonates.

Cytomegalovirus DNA detection in pregnant women with a high IgG avidity index: a valuable tool for diagnosing non-primary infections?

BACKGROUND/AIM

Congenital human cytomegalovirus infection (cCMV) is the commonest congenital infection, and it can result in hearing loss and neurodevelopmental delay. Even if primary infections are more frequent and cause more severe congenital cCMV manifestations compared to NPIs, and despite partial protection from maternal immunity, the highest birth prevalence of cCMV is observed in seropositive women with non-primary CMV infection (NPI). Given that NPI contribute significantly to the overall burden of cCMV, their accurate diagnosis of NPI remains clinically important. Considering that the serological testing for CMV infection is not always reliable, we sought to determine whether detection of CMV DNA in pregnant women with a high IgG avidity index (AI) can help diagnose NPI.

MATERIALS AND METHODS

Human CMV serology screening (IgG, IgM, and IgG AI) was performed for confirmation of CMV infection in serum samples from mainly pregnant women with indications of CMV infection due to IgG⁺ and IgM⁺-positive samples in other laboratories. Pregnant women (or those with termination of pregnancy during the last period) with adequate IgG levels to perform IgG AI were included. Demographic data and mean gestation week at the time of screening were recorded. Serological testing was performed using CE-IVD commercial kits. CMV DNAemia detection by real time PCR (RT-PCR) was applied to confirm suspected CMV infection.

RESULTS

Nine-hundred and thirty-four pregnant women CMV IgG positive with adequate IgG titers for AI testing were included in the study. The percentage of women with a high AI was 71.8% (671/934); among them, nearly 2.4% (16/671) had presence of CMV DNA. Also, 12.4% of women (116/934) had intermediate IgG AI and 15.7% of women (147/934) had low IgG AI. The presence of CMV DNA was observed in 13.8% (16/116) and 39.5% (58/147) of the groups with intermediate and low IgG AI, respectively. A high CMV IgG AI was associated with a negative CMV PCR status (p-value <.00001).

CONCLUSIONS

CMV DNA was present in 2.4% of seropositive women with high IgG AI, indicating active NPI and thus, harboring the risk of cCMV sequelae to the fetus. Moreover, the incidence of NPI may have been underestimated due to single timepoint testing. In order to detect CMV NPI in a seropositive woman, regular and frequent serology testing as well as detection of CMV DNAemia are required which render the whole diagnostic process impractical and not cost-effective.

Antenatal imaging and clinical outcome in congenital CMV infection: A field-wide systematic review and meta-analysis

OBJECTIVES

Postnatal outcome in fetuses with congenital cytomegalovirus infection (cCMV) varies from asymptomatic infection to severe neurodevelopmental impairment. Αntenatal biomarkers of long-term clinical outcome, have yet to be established. Α systematic review and meta-analysis was performed to examine whether prenatal cerebral ultrasonography (US) and magnetic resonance imaging (MRI) findings in cCMV fetuses may predict clinical outcome.

METHODS

PubMed and the Web of Science were systematically searched to identify studies reporting on any prenatal US and/or MRI imaging of fetuses with cCMV as well as their postnatal clinical outcome. All reported associations between imaging and postnatal clinical outcome were systematically extracted. Where appropriate, the reported associations were quantitatively synthesized within Bayesian random-effects meta-analyses.

RESULTS

A total of 1336 studies were screened to identify 26 eligible observational studies. Overall, 4181 fetuses were studied, of which 1518 had been diagnosed with cCMV. All studies performed fetal US while in 14 (54%) MRI was also performed. Studies substantially varied in timing of fetal imaging, reporting of abnormalities, definition of poor outcome and statistical analysis. Among studies reporting on statistical significance, 6/6 for US and 3/4 for MRI identified significant associations between imaging findings and outcome. In our meta-analyses, within isolated abnormalities, only microcephaly had greater than 95% probability of being associated with poor outcome (OR 26.7; 95% CI, 1.44-1464.5; I², 19%). Effect sizes for US were higher than those for MRI findings.

CONCLUSIONS

Although studies displayed significant heterogeneity in both methodology and analytical decisions, it became evident that when both prenatal cerebral US and MRI are normal the negative predictive value of poor outcome is high. This is important for clinicians when consulting pregnant women. Need to standardize practices and definitions become evident.
