Bictegravir Use During Pregnancy: A Multicenter Retrospective Analysis Evaluating HIV Viral Suppression and Perinatal Outcomes.

This study describes the largest cohort to date (n = 147) of pregnant patients with human immunodeficiency virus (HIV) on bictegravir (BIC). BIC in pregnancy was associated with high levels of viral suppression and perinatal outcomes similar to those in the published literature. These findings support consideration for the use of BIC in managing HIV during pregnancy.

Society for Maternal-Fetal Medicine Consult Series #69: Hepatitis B in pregnancy: updated guidelines.

More than 290 million people worldwide, and almost 2 million people in the United States, are infected with hepatitis B virus, which can lead to chronic hepatitis B, a vaccine-preventable communicable disease. The prevalence of chronic hepatitis B infection in pregnancy is estimated to be 0.7% to 0.

Outcomes Following Extracorporeal Membrane Oxygenation for Severe COVID-19 in Pregnancy or Post Partum.

Importance: Existing reports of pregnant patients with COVID-19 disease who require extracorporeal membrane oxygenation (ECMO) are limited, with variable outcomes noted for the maternal-fetal dyad.

Objective: To examine maternal and perinatal outcomes associated with ECMO used for COVID-19 with respiratory failure during pregnancy.

Design, Setting, And Participants: This retrospective multicenter cohort study examined pregnant and postpartum patients who required ECMO for COVID-19 respiratory failure at 25 hospitals across the US.

An Overview of Antiviral Treatments in Pregnancy.

Viral infections pose unique threats to pregnant persons and their infants. As the frequency of epidemics caused by novel pathogens increases, understanding pregnancy-specific considerations for antiviral treatments is critical for obstetric and nonobstetric providers alike. The use of pharmacologic therapeutics in pregnancy, which include antivirals, pathogen-specific antibodies, and vaccines, is limited due to the lack of purposeful, methodologic, pharmacometrics analyses in this special population.

Antiretroviral Options and Treatment Decisions During Pregnancy.

The majority of pediatric human immunodeficiency virus (HIV) infections are the result of vertical transmissions that occur during pregnancy, childbirth, and breastfeeding. The treatment of all pregnant persons living with HIV remains a global health initiative. Early and consistent use of antiretroviral therapy throughout pregnancy and childbirth drastically reduces the risk of perinatal transmission of HIV, resulting in fewer children living with the disease worldwide.

Antibody response, neutralizing potency, and transplacental antibody transfer following SARS-CoV-2 infection versus mRNA-1273, BNT162b2 COVID-19 vaccination in pregnancy.

Objective: To improve our understanding of the immune response, including the neutralization antibody response, following COVID-19 vaccination in pregnancy.

Methods: This was a prospective cohort study comprising patients with PCR-confirmed SARS-CoV-2 infection and patients who received both doses of mRNA COVID-19 vaccine (mRNA-1273, BNT162b2) in pregnancy recruited from two hospitals in Atlanta, GA, USA. Maternal blood and cord blood at delivery were assayed for anti-receptor binding domain (RBD) IgG, IgA and IgM, and neutralizing antibody.

Attitudes on breast feeding among persons with HIV who have given birth and their perceptions of coercion during counseling on safe infant feeding practices.

Persons with HIV can receive mixed messages about the safety of breastfeeding. We sought to assess if they felt coerced to formula feed when counseled about practices to reduce HIV transmission. Persons with HIV who had given birth were eligible to complete a survey to describe their experiences with infant feeding counseling and if they felt coerced to formula feed.

Perception of coercion during contraceptive counseling among individuals with HIV.

Objective: Historically, individuals with HIV have reported feeling coerced during contraceptive counseling or experienced forced sterilization. The purpose of this study was to assess perceptions of coercion related to counseling and influence on postpartum contraceptive choice among individuals with HIV.

Methods: This is a mixed methods study conducted in Georgia, North Carolina, Pennsylvania, and South Carolina between March 2020 and June 2021.

Covid-19 vaccination in pregnancy.

Pregnancy is an independent risk factor for severe covid-19. Vaccination is the best way to reduce the risk for SARS-CoV-2 infection and limit its morbidity and mortality. The current recommendations from the World Health Organization, Centers for Disease Control and Prevention, and professional organizations are for pregnant, postpartum, and lactating women to receive covid-19 vaccination.

Placental Injury and Antibody Transfer after Coronavirus Disease 2019 in Pregnancy.

Background: We examined the relationship between placental histopathology and transplacental antibody transfer in pregnant patients after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Methods: Differences in plasma concentrations of anti-receptor biding domain (RBD) immunoglobulin (Ig)G antibodies in maternal and cord blood were analyzed according to presence of placental injury.

Results: Median anti-RBD IgG concentrations in cord blood with placental injury (n = 7) did not differ significantly from those without injury (n = 16) (median 2.

COVID-19 booster vaccination during pregnancy enhances maternal binding and neutralizing antibody responses and transplacental antibody transfer to the newborn (DMID 21-0004).

Importance: COVID-19 vaccination is recommended during pregnancy for the protection of the mother. Little is known about the immune response to booster vaccinations during pregnancy.

Objective: To measure immune responses to COVID-19 primary and booster mRNA vaccination during pregnancy and transplacental antibody transfer to the newborn.

Outcomes of pregnant patients treated with REGEN-COV during the COVID-19 pandemic.

Background: Pregnant patients with SARS-CoV-2 infection are at increased risk for severe disease including hospitalization, intensive care admission, ventilatory support, and death. Although pregnant patients were excluded from investigational trials for pharmacologic treatments for COVID-19 illness, the National Institutes of Health treatment guidelines state that efficacious treatments should not be withheld from pregnant patients. An infusion of casirivimab and imdevimab (REGEN-COV), a monoclonal antibody therapy, was shown to reduce the risk of COVID-19-related hospitalization or death from any cause and resolved symptoms and reduced SARS-CoV-2 viral load more rapidly than placebo.

The Effect of Antiretroviral Therapy for the Treatment of Human Immunodeficiency Virus (HIV)-1 in Pregnancy on Gestational Weight Gain.

Background: Gestational weight gain above Institute of Medicine recommendations is associated with increased risk of pregnancy complications. The goal was to analyze the association between newer HIV antiretroviral regimens (ART) on gestational weight gain.

Methods: A retrospective cohort study of pregnant women with HIV-1 on ART.

Pharmacokinetics of Atazanavir Boosted With Cobicistat in Pregnant and Postpartum Women With HIV.

Background: This study evaluated atazanavir and cobicistat pharmacokinetics during pregnancy compared with postpartum and in infant washout samples.

Setting: A nonrandomized, open-label, parallel-group, multicenter prospective study of atazanavir and cobicistat pharmacokinetics in pregnant women with HIV and their children.

Methods: Intensive steady-state 24-hour pharmacokinetic profiles were performed after administration of 300 mg of atazanavir and 150 mg of cobicistat orally in fixed-dose combination once daily during the second trimester, third trimester, and postpartum.

Reduced angiovasculogenic and increased inflammatory profiles of cord blood cells in severe but not mild preeclampsia.

Preeclampsia (PE) is a prevalent pregnancy disorder that leads to high maternal and fetal morbidity and mortality. While defective vascular development and angiogenesis in placenta are known as crucial pathological findings, its pathophysiological mechanism remains elusive. To better understand the effects of PE on angio-vasculogenesis and inflammatory networks in the fetus and to identify their biological signatures, we investigated the quantitative and functional characteristics of cord blood-derived mononuclear cells (CB-MNCs) and CD31-positive MNCs.

Sociodemographic Predictors of SARS-CoV-2 Infection in Obstetric Patients, Georgia, USA.

We conducted a cohort study to determine sociodemographic risk factors for severe acute respiratory syndrome coronavirus 2 infection among obstetric patients in 2 urban hospitals in Atlanta, Georgia, USA. Prevalence of infection was highest among women who were Hispanic, were uninsured, or lived in high-density neighborhoods.
