The Women and Children's Infectious Diseases Center: An integrated approach to congenital infectious diseases.

Clin Invest Med 2019 Jan 30;41(4):E211-E212. Epub 2019 Jan 30.

Department of Pediatrics, Faculty of Medicine, Université de Montréal, Montréal, QC.

Congenital infectious diseases, transmitted during the course of pregnancy, are estimated to affect nearly one in every hundred births worldwide. These infections may be associated with fetal and infant adverse health outcomes, due to congenital malformations caused by in utero transmission of the infectious organism itself (as is the case with cytomegalovirus, toxoplasmosis, syphilis and Zika virus), or due to chronic infection in the infant (as is the case with human immunodeficiency virus [HIV] and hepatitis B and C). In addition, children who are exposed, yet uninfected, may still suffer from the consequences of exposure to infectious pathogens or to the drugs given to treat pregnant women and prevent in utero transmission (as may be the case with HIV infection).

Dengue Virus Immunity Increases Zika Virus-Induced Damage during Pregnancy.

Immunity 2019 Jan 30. Epub 2019 Jan 30.

Department of Microbiology, Icahn School of Medicine at Mount Sinai, New York, NY, USA. Electronic address:

Zika virus (ZIKV) has recently been associated with birth defects and pregnancy loss after maternal infection. Because dengue virus (DENV) and ZIKV co-circulate, understanding the role of antibody-dependent enhancement in the context of pregnancy is critical. Here, we showed that the presence of DENV-specific antibodies in ZIKV-infected pregnant mice significantly increased placental damage, fetal growth restriction, and fetal resorption. Read More

Does prior dengue virus exposure worsen clinical outcomes of Zika virus infection? A systematic review, pooled analysis and lessons learned.

PLoS Negl Trop Dis 2019 Jan 25;13(1):e0007060. Epub 2019 Jan 25.

Viral Diseases Branch, Walter Reed Army Institute of Research, Silver Spring, MD, United States of America.

Zika virus (ZIKV) recently caused a pandemic complicated by Guillain-Barre syndrome (GBS) and birth defects. ZIKV is structurally similar to the dengue viruses (DENV) and in vitro studies suggest antibody dependent enhancement occurs in ZIKV infections preceded by DENV; however, the clinical significance of this remains unclear. We undertook a PRISMA-adherent systematic review of all current human and non-human primate (NHP) data to determine if prior infection with DENV, compared to DENV-naïve hosts, is associated with a greater risk of ZIKV clinical complications or greater ZIKV peak viremia in vivo.

J Pediatric Infect Dis Soc 2018 Dec;7(suppl_2):S60-S66

Department of Pediatrics, University of Wisconsin-Madison.

In utero infection with Zika virus (ZIKV) during pregnancy can lead to the development of birth defects and postnatal deficits. A nonhuman primate (NHP) model of congenital ZIKV infection can help fill the gaps in knowledge where tissue studies are required to define viral pathogenesis and identify targets for therapeutic intervention. This model system has already identified critical features of ZIKV pathogenesis in congenital infection. Read More

The Zika Virus Infection in Pregnancy: Review and Implications for Research and Care of Women and Infants in Affected Areas.

P R Health Sci J 2018 Dec;37(Special Issue):S66-S72

Maternal-Infant Studies Center (CEMI).

The world has encountered a new and serious epidemic which has disproportionately affected fetuses and infants. What makes the Zika virus (ZIKV) epidemic such a threat in our times, is that a whole generation can be affected by birth defects caused by a seemingly innocuous maternal infection, which in most cases go unnoticed and undiagnosed. Spreading to over 80 countries and affecting millions, it is associated with severe birth defects known as congenital Zika syndrome (CZS), which include fetal brain development abnormalities (microcephaly and brain calcifications), retinal abnormalities, and contractures and hypertonia of the extremities.

Evaluation of non-adherence to anti-retroviral therapy, the associated factors and infant outcomes among HIV-positive pregnant women: a prospective cohort study in Lesotho.

Pan Afr Med J 2018 31;30:239. Epub 2018 Jul 31.

Department of Health Research Methods, Evidence and Impact McMaster University, Hamilton, Canada.

Introduction: Success in addressing prevention of mother-to-child transmission of HIV depends largely on good adherence to anti-retroviral therapy (ART) by pregnant women. Knowledge of the levels of ART adherence among pregnant women is essential to inform strategies to prevent or reduce HIV transmission rates, particularly in African settings. Aim: the primary objective of this study was to measure adherence to anti-retroviral therapy (ART) among pregnant women living with human immunodeficiency virus (HIV). Read More

Cross-Reactivity of Virus-Specific CD8+ T Cells Against Allogeneic HLA-C: Possible Implications for Pregnancy Outcome.

Front Immunol 2018 6;9:2880. Epub 2018 Dec 6.

Department of Immunohematology and Blood Transfusion, Leiden University Medical Center, Leiden, Netherlands.

Heterologous immunity of virus-specific T cells poses a potential barrier to transplantation tolerance. Cross-reactivity to HLA-A and -B molecules has broadly been described, whereas responses to allo-HLA-C have remained ill defined. In contrast to the transplant setting, HLA-C is the only polymorphic HLA molecule expressed by extravillous trophoblasts at the maternal-fetal interface during pregnancy. Read More

Vaccination has been a successful strategy in influenza prevention. However, despite the safety and efficacy of the vaccines, they can cause adverse events following immunization (AEFI). Moreover, due to the vaccination success, most of vaccine-preventable diseases (VPD) have become rare, and public attention has been shifted from VPD to the AEFI associated with vaccination.

Rift Valley fever virus induces fetal demise in Sprague-Dawley rats through direct placental infection.

Sci Adv 2018 Dec 5;4(12):eaau9812. Epub 2018 Dec 5.

Center for Vaccine Research, University of Pittsburgh, Pittsburgh, PA, USA.

Rift Valley fever virus (RVFV) infections in pregnant livestock cause high rates of fetal demise; miscarriage in pregnant women has also been associated with RVFV infection. To address how RVFV infection during pregnancy causes detrimental effects on the fetus, we developed a pregnant rodent model of RVFV infection. We found that pregnant rats were more susceptible to RVFV-induced death than their nonpregnant counterparts and that RVFV infection resulted in intrauterine fetal death and severe congenital abnormalities, even in pups from infected asymptomatic pregnant rats.
