Characteristics of Women of Reproductive Age with Laboratory-Confirmed SARS-CoV-2 Infection by Pregnancy Status - United States, January 22-June 7, 2020

The COVID-19 pandemic through eyes of a NYC fertility center: a unique learning experience with often unexpected results

Affecting basic tenets of human existence such as health, economic as well as personal security and, of course, reproduction, the COVID-19 pandemic transcended medical specialties and professional disciplines. Yet, six months into the pandemic, there still exists no consensus on how to combat the virus in absence of a vaccine. Facing unprecedented circumstances, and in absence of real evidence on how to proceed, our organization early in the pandemic decided to act independently from often seemingly irrational guidance and, instead, to carefully follow a quickly evolving COVID-19 literature. Here described is the, likely, unique journey of a fertility center that maintained services during peaks of COVID-19 and political unrest that followed. Closely following publicly available data, we recognized relatively early that New York City and other East Coast regions, which during the initial COVID-19 wave between March and May represented the hardest-hit areas in the country, during the second wave, beginning in June and still in progress, remained almost completely unaffected. In contrast, south western regions, almost completely unaffected by the initial wave, were severely affected in the second wave. These two distinctively different infectious phenotypes suggested two likely explanations: The country was witnessing infections with two different SARS-CoV-2 viruses and NYC (along with the East Coast) acquired during the first wave much better immunity to the virus than south western regions. Both hypotheses since have been confirmed: East and West Coasts, indeed, were initially infected by two distinctively different lineages of the virus, with the East Coast lineage being 10-times more infectious. In addition, immunologists discovered an up to this point unknown long-term anti-viral innate (cellular) immune response which offers additional and much broader anti-viral immunity than the classical adaptive immunity via immobilizing antibodies that has been known for decades. Consequently, we predict that in the U.S., even in absence of an available vaccine, COVID-19, by September-October, will be at similarly low levels as are currently seen in NYC and other East Coast regions (generally < 1% test-positivity). We, furthermore, predict that, if current mitigation measures are maintained and no newly aggressive mutation of the virus enters the country, a significant fall-wave of COVID-19, in combination with the usual fall wave of influenza, appears unlikely. To continue serving patients uninterrupted throughout the pandemic, turned for all of our center's staff into a highly rewarding experience, garnered respect and appreciation from patients, and turned into an absolutely unique learning experience.

Impact of Covid-19 in pregnancy on mother's psychological status and infant's neurobehavioral development: a longitudinal cohort study in China

BACKGROUND

Evidence concerning the long-term impact of Covid-19 in pregnancy on mother's psychological disorder and infant's developmental delay is unknown.

METHODS

This study is a longitudinal single-arm cohort study conducted in China between May 1 and July 31, 2020. Seventy-two pregnant patients with Covid-19 participated in follow-up surveys until 3 months after giving birth (57 cases) or having abortion (15 cases). We collected data from medical records regarding Covid-19, delivery or abortion, testing results of maternal and neonatal specimens, and questionnaires of quarantine, mother-baby separation, feeding, and measuring of mothers' mental disorders and infants' neurobehavioral disorders.

RESULTS

All cases infected in the first trimester and 1/3 of cases infected in the second trimester had an abortion to terminate the pregnancy. 22.2% of pregnant patients were suffering from post-traumatic stress disorder or depression at 3 months after delivery or induced abortion. Among 57 live births, only one neonate was positive of nucleic acid testing for throat swab, but negative in repeated tests subsequently. The median duration of mother-baby separation was 35 days (interquartile range 16 to 52 days). After the termination of maternal quarantine, 49.1% of mothers chose to prolong the mother-baby separation (median 8 days; IQR 5 to 23 days). The breastfeeding rate was 8.8% at 1 week after birth, 19.3% at the age of 1 month, and 36.8% at the age of 3 months, respectively. The proportion of "monitoring" and "risk" in the social-emotional developmental domain at the age of 3 months was 22.7% and 63.6%, respectively. After the adjustment of preterm, neonatal sex, admitted to NICU, and the mother's Covid-19 condition, the negative associations were significantly identified (p < 0.05) between mother-baby separation days and three developmental domains: communication, gross motor, and personal-social.

CONCLUSIONS

There is no definite evidence on vertical transmission of SARS-CoV-2. In addition to control infection risk, researchers and healthcare providers should pay more attention to maternal mental health and infant's feeding, closeness with parents, and early development.

Pregnancy Outcomes Among Women With and Without Severe Acute Respiratory Syndrome Coronavirus 2 Infection

IMPORTANCE

Published data suggest that there are increased hospitalizations, placental abnormalities, and rare neonatal transmission among pregnant women with coronavirus disease 2019 (COVID-19).

OBJECTIVES

To evaluate adverse outcomes associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in pregnancy and to describe clinical management, disease progression, hospital admission, placental abnormalities, and neonatal outcomes.

DESIGN, SETTING, AND PARTICIPANTS

This observational cohort study of maternal and neonatal outcomes among delivered women with and without SARS-CoV-2 during pregnancy was conducted from March 18 through August 22, 2020, at Parkland Health and Hospital System (Dallas, Texas), a high-volume prenatal clinic system and public maternity hospital with widespread access to SARS-CoV-2 testing in outpatient, emergency department, and inpatient settings. Women were included if they were tested for SARS-CoV-2 during pregnancy and delivered. For placental analysis, the pathologist was blinded to illness severity.

EXPOSURES

SARS-CoV-2 infection during pregnancy.

MAIN OUTCOMES AND MEASURES

The primary outcome was a composite of preterm birth, preeclampsia with severe features, or cesarean delivery for abnormal fetal heart rate among women delivered after 20 weeks of gestation. Maternal illness severity, neonatal infection, and placental abnormalities were described.

RESULTS

From March 18 through August 22, 2020, 3374 pregnant women (mean [SD] age, 27.6 [6] years) tested for SARS-CoV-2 were delivered, including 252 who tested positive for SARS-CoV-2 and 3122 who tested negative. The cohort included 2520 Hispanic (75%), 619 Black (18%), and 125 White (4%) women. There were no differences in age, parity, body mass index, or diabetes among women with or without SARS-CoV-2. SARS-CoV-2 positivity was more common among Hispanic women (230 [91%] positive vs 2290 [73%] negative; difference, 17.9%; 95% CI, 12.3%-23.5%; P < .001). There was no difference in the composite primary outcome (52 women [21%] vs 684 women [23%]; relative risk, 0.94; 95% CI, 0.73-1.21; P = .64). Early neonatal SARS-CoV-2 infection occurred in 6 of 188 tested infants (3%), primarily born to asymptomatic or mildly symptomatic women. There were no placental pathologic differences by illness severity. Maternal illness at initial presentation was asymptomatic or mild in 239 women (95%), and 6 of those women (3%) developed severe or critical illness. Fourteen women (6%) were hospitalized for the indication of COVID-19.

CONCLUSIONS AND RELEVANCE

In a large, single-institution cohort study, SARS-CoV-2 infection during pregnancy was not associated with adverse pregnancy outcomes. Neonatal infection may be as high as 3% and may occur predominantly among asymptomatic or mildly symptomatic women. Placental abnormalities were not associated with disease severity, and hospitalization frequency was similar to rates among nonpregnant women.

What immunological and hormonal protective factors lower the risk of COVID-19 related deaths in pregnant women?

Despite anticipated increased risk of COVID-19 and increased expression of the SARS CoV-2 receptor (ACE2), the relatively low mortality of pregnant women with COVID-19 has been an area of wonder. The immunological changes predominantly inclining to anti-inflammatory state, which is augmented by placental hormones' immune modulating action, looks against with COVID-19 inflammatory reaction leading to cytokine storm and multiple organ failure. Unlike many other viral infections, the bilateral immune activation of COVID-19 may preferentially make pregnant women at low risk. Taking the physiological advantage of pregnant women, potential clinical trials are proposed. Quite a large number of epidemiological and obstetrics related studies have addressed the cases of women with COVID-19. However, to the best of the author's knowledge, little is done to explore the physiological internal milieu of pregnant women in relation to COVID-19. This review provides an insight into how the hormonal and immunological changes in pregnancy potentially reduce SARS-CoV-2-mediated inflammatory response.

COVID-19 coagulopathy in pregnancy: Critical review, preliminary recommendations, and ISTH registry-Communication from the ISTH SSC for Women's Health

BACKGROUND

Novel coronavirus (SARS-CoV-2), which causes COVID-19, has thus far affected more than 15 million individuals, resulting in more than 600 000 deaths worldwide, and the number continues to rise. In a large systematic review and meta-analysis of the literature including 2567 pregnant women, 7% required intensive care admission, with a maternal mortality ~1% and perinatal mortality below 1%. There has been a rapid increase in publications on COVID-19-associated coagulopathy, including disseminated intravascular coagulopathy and venous thromboembolism, in the non-pregnant population, but very few reports of COVID-19 coagulopathy during pregnancy; leaving us with no guidance for care of this specific population.

METHODS

This is a collaborative effort conducted by a group of experts that was reviewed, critiqued, and approved by the International Society on Thrombosis and Haemostasis Subcommittee for Women's Health Issues in Thrombosis and Hemostasis. A structured literature search was conducted, and the quality of current and emerging evidence was evaluated. Based on the published studies in the non-pregnant and pregnant population with a moderate to high risk of bias as assessed by Newcastle-Ottawa scale and acknowledging the absence of data from randomized clinical trials for management of pregnant women infected with SARS-CoV-2, a consensus in support of a guidance document for COVID-19 coagulopathy in pregnancy was identified.

RESULTS AND CONCLUSIONS

Specific hemostatic issues during pregnancy were highlighted, and preliminary recommendations to assist in the care of COVID-19-affected pregnant women with coagulopathy or thrombotic complications were developed. An international registry to gather data to support the management of COVID-19 and associated coagulopathy in pregnancy was established.

Coronavirus Disease 2019 in Pregnancy: The Experience at an Urban Safety Net Hospital

Shortly after the identification of a novel coronavirus, the coronavirus disease 2019, or COVID-19, a global pandemic was declared. There have been conflicting data about the severity of COVID-19 disease course in pregnant women, with most US data suggesting an increase in severity and increased need for hospitalization and intubation in obstetric patients. In the general population, the disease is more common among racial and ethnic minority populations, and severity is increased with comorbid conditions and obesity. The purpose of this study is to characterize COVID-19 infection in pregnancy in a population of women getting prenatal care at an urban safety-net hospital. Beginning in April, 2020, all women were tested at admission for delivery, and additionally as an outpatient if presenting with COVID-19 symptoms. In three months, there were 208 discrete women tested and 23 (11.1%) who were positive for COVID-19. The incidence of COVID-19 was 5.1% in asymptomatic women being screened upon admission to the hospital. There was a high prevalence of obesity (68.2%) and other comorbid conditions (43.5%) in this population, and all patients were racial/ethnic minorities. Despite these risk factors, the patients uniformly had either mild or asymptomatic disease. No symptomatic patients required hospitalization for their infection. In this population of pregnant women at high risk for severe COVID-19 infection, only mild disease was observed.

Protocol-Driven Intensive Outpatient Management of Pregnant Patients With Symptomatic Coronavirus Disease 2019

Background

Reports of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have focused on pregnant women hospitalized due to moderate to severe coronavirus disease 2019 (COVID-19) or asymptomatic women diagnosed through universal screening at the time of obstetric admission. Many pregnant women who have symptomatic SARS-CoV-2 infection may not meet criteria for hospitalization; however, whether and how these women can be managed safely in outpatient setting is not well described.

Methods

We sought to describe the time to symptom and viral clearance and to identify predictors of hospitalization to better understand the safety of monitoring pregnant patients with symptomatic COVID-19 in the outpatient setting. We performed a retrospective cohort study of pregnant patients with symptomatic, confirmed COVID-19 illness at a large, academic medical center. Patients had systematic telehealth follow up by a clinician team to assess for symptoms, provide virtual prenatal care, and arrange in-person visits when appropriate in a dedicated outpatient center. Data were collected via chart abstraction.

Results

Of 180 pregnant patients presenting with symptoms and undergoing reverse-transcription polymerase chain reaction (RT-PCR) testing, 67 patients with confirmed COVID-19 infection were identified during the study period. Nineteen (28%) required acute care given worsening of COVID-19 symptoms, and 95% of these were directed to this acute care setting due to symptom severity telehealth evaluation. Nine women (13%) were admitted to the hospital given worsening symptoms, 3 required intensive care unit care, 2 required ventilatory support, and 2 required delivery. Women with the presenting symptoms of fever, cough, shortness of breath, chest pain, or nausea and vomiting were more likely to require admission. The median duration from initial positive test to RT-PCR viral clearance was 26 days. Disease progression, time to viral clearance, and duration of symptoms did not vary significantly by trimester of infection.

Conclusions

Management of the majority of pregnant women with symptomatic COVID-19 illness can be accomplished in the outpatient setting with intensive and protocol-driven monitoring for symptom progression.

Clinical manifestations and perinatal outcomes of pregnant women with COVID-19: a systematic review and meta-analysis

This systematic review and meta-analysis aimed to evaluate the impact of COVID-19 on pregnant women. We searched for qualified studies in PubMed, Embase, and Web of Science. The clinical characteristics of pregnant women with COVID-19 and their infants were reported as means and proportions with 95% confidence interval. Eleven studies involving with 9032 pregnant women with COVID-19 and 338 infants were included in the meta-analysis. Pregnant women with COVID-19 have relatively mild symptoms. However, abnormal proportions of laboratory parameters were similar or even increased, compared to general population. Around 30% of pregnant women with COVID-19 experienced preterm delivery, whereas the mean birth weight was 2855.9 g. Fetal death and detection of SARS-CoV-2 were observed in about 2%, whereas neonatal death was found to be 0.4%. In conclusion, the current review will serve as an ideal basis for future considerations in the treatment and management of COVID-19 in pregnant women.

The first consecutive 5000 patients with Coronavirus Disease 2019 from Qatar; a nation-wide cohort study

Background

There are limited data on Coronavirus Disease 2019 (COVID-19) outcomes at a national level, and none after 60 days of follow up. The aim of this study was to describe national, 60-day all-cause mortality associated with COVID-19, and to identify risk factors associated with admission to an intensive care unit (ICU).

Methods

This was a retrospective cohort study including the first consecutive 5000 patients with COVID-19 in Qatar who completed 60 days of follow up by June 17, 2020. The primary outcome was all-cause mortality at 60 days after COVID-19 diagnosis. In addition, we explored risk factors for admission to ICU.

Results

Included patients were diagnosed with COVID-19 between February 28 and April 17, 2020. The majority (4436, 88.7%) were males and the median age was 35 years [interquartile range (IQR) 28–43]. By 60 days after COVID-19 diagnosis, 14 patients (0.28%) had died, 10 (0.2%) were still in hospital, and two (0.04%) were still in ICU. Fatal COVID-19 cases had a median age of 59.5 years (IQR 55.8–68), and were mostly males (13, 92.9%). All included pregnant women (26, 0.5%), children (131, 2.6%), and healthcare workers (135, 2.7%) were alive and not hospitalized at the end of follow up.

A total of 1424 patients (28.5%) required hospitalization, out of which 108 (7.6%) were admitted to ICU. Most frequent co-morbidities in hospitalized adults were diabetes (23.2%), and hypertension (20.7%). Multivariable logistic regression showed that older age [adjusted odds ratio (aOR) 1.041, 95% confidence interval (CI) 1.022–1.061 per year increase; P < 0.001], male sex (aOR 4.375, 95% CI 1.964–9.744; P < 0.001), diabetes (aOR 1.698, 95% CI 1.050–2.746; P 0.031), chronic kidney disease (aOR 3.590, 95% CI 1.596–8.079, P 0.002), and higher BMI (aOR 1.067, 95% CI 1.027–1.108 per unit increase; P 0.001), were all independently associated with increased risk of ICU admission.

Conclusions

In a relatively younger national cohort with a low co-morbidity burden, COVID-19 was associated with low all-cause mortality. Independent risk factors for ICU admission included older age, male sex, higher BMI, and co-existing diabetes or chronic kidney disease.

Post lockdown COVID-19 seroprevalence and circulation at the time of delivery, France

BACKGROUND

To fight the COVID-19 pandemic, lockdown has been decreed in many countries worldwide. The impact of pregnancy as a severity risk factor is still debated, but strict lockdown measures have been recommended for pregnant women.

OBJECTIVES

To evaluate the impact of the COVID-19 pandemic and lockdown on the seroprevalence and circulation of SARS-CoV-2 in a maternity ward in an area that has been significantly affected by the virus.

STUDY DESIGN

Prospective study at the Antoine Béclère Hospital maternity ward (Paris area, France) from May 4 (one week before the end of lockdown) to May 31, 2020 (three weeks after the end of lockdown). All patients admitted to the delivery room during this period were offered a SARS-CoV-2 serology test as well concomitant SARS-CoV-2 RT-PCR on one nasopharyngeal sample.

RESULTS

A total of 249 women were included. Seroprevalence of SARS-CoV-2 was 8%. The RT-PCR positive rate was 0.5%. 47.4% of the SARS-CoV-2-IgG-positive pregnant women never experienced any symptoms. A history of symptoms during the epidemic, such as fever (15.8%), myalgia (36.8%) and anosmia (31.6%), was suggestive of previous infection.

CONCLUSIONS

Three weeks after the end of French lockdown, SARS-CoV-2 infections were scarce in our region. A very high proportion of SARS-CoV-2-IgG-negative pregnant women, which is comparable to that of the general population, must be taken into consideration in the event of a resurgence of the pandemic. The traces of a past active circulation of the virus in this fragile population during the spring wave should encourage public health authorities to take specific measures for this independent at-risk group, in order to reduce viral circulation in pregnant patients.

SARS-CoV-2 (COVID-19) infection in pregnant women: characterization of symptoms and syndromes predictive of disease and severity through real-time, remote participatory epidemiology

OBJECTIVE

To test whether pregnant and non-pregnant women differ in COVID-19 symptom profile and severity. To extend previous investigations on hospitalized pregnant women to those who did not require hospitalization.

DESIGN

Observational study prospectively collecting longitudinal (smartphone application interface) and cross-sectional (web-based survey) data.

SETTING

Community-based self-participatory citizen surveillance in the United Kingdom, Sweden and the United States of America.

POPULATION

Two female community-based cohorts aged 18-44 years. The discovery cohort was drawn from 1,170,315 UK, Sweden and USA women (79 pregnant tested positive) who self-reported status and symptoms longitudinally via smartphone. The replication cohort included 1,344,966 USA women (134 pregnant tested positive) who provided cross-sectional self-reports.

METHODS

Pregnant and non-pregnant were compared for frequencies of symptoms and events, including SARS-CoV-2 testing and hospitalization rates. Multivariable regression was used to investigate symptoms severity and comorbidity effects.

RESULTS

Pregnant and non-pregnant women positive for SARS-CoV-2 infection were not different in syndromic severity. Pregnant were more likely to have received testing than non-pregnant, despite reporting fewer symptoms. Pre-existing lung disease was most closely associated with the syndromic severity in pregnant hospitalized women. Heart and kidney diseases and diabetes increased risk. The most frequent symptoms among all non-hospitalized women were anosmia [63% pregnant, 92% non-pregnant] and headache [72%, 62%]. Cardiopulmonary symptoms, including persistent cough [80%] and chest pain [73%], were more frequent among pregnant women who were hospitalized.

CONCLUSIONS

Symptom characteristics and severity were comparable among pregnant and non-pregnant women, except for gastrointestinal symptoms. Consistent with observations in non-pregnant populations, lung disease and diabetes were associated with increased risk of more severe SARS-CoV-2 infection during pregnancy.

Severe COVID-19 in Third Trimester Pregnancy: Multidisciplinary Approach

The rapidly expanding cases of the coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have exposed vulnerable populations, including pregnant women to an unprecedented public health crisis. Recent data show that pregnancy in COVID-19 patients is associated with increased hospitalization, admission of the intensive care unit, and intubation. However, very few resources exist to guide the multidisciplinary team in managing critically ill pregnant women with COVID-19. We report our experience with managing a morbidly obese pregnant woman at 36 weeks' gestation with history of asthma and malignancy who presented with persistent respiratory symptoms at an outside hospital after being tested positive for SARS-CoV-2 polymerase chain reaction (PCR). Early in the course of the hospitalization, patient received remdesivir, convalescent plasma, bronchodilator, systemic steroids, and IV heparin for COVID-19 and concomitant asthma exacerbation and pulmonary embolism. Due to increasing oxygen requirements, she was eventually intubated and transferred to our institution for higher level of care. Respiratory acidosis, severe hypoxemia, and vent asynchrony were managed with vent setting adjustment and paralytics. After 12 hours from spontaneous rupture of her membranes and with stabilization of maternal status, patient underwent a term cesarean delivery for nonreassuring fetal heart tracing. The neonate was discharged on the 2^nd day of life, while the patient was extubated on the 6^th postpartum day and was discharged to acute inpatient rehabilitation facility on the 19^th hospital day. This report highlights the disease progression of COVID-19 in a pregnant woman, the clinical challenges in the critical care aspect of patient management, and the proposed multidisciplinary strategies utilizing an algorithmic approach to optimize maternal and neonatal outcomes.

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.

Compassionate Use of Remdesivir in Pregnant Women with Severe Covid-19

Background

Remdesivir is efficacious for severe coronavirus disease 2019 (COVID-19) in adults, but data in pregnant women are limited. We describe outcomes in the first 86 pregnant women with severe COVID-19 who were treated with remdesivir.

Methods

The reported data span 21 March to 16 June 2020 for hospitalized pregnant women with polymerase chain reaction–confirmed severe acute respiratory syndrome coronavirus 2 infection and room air oxygen saturation ≤94% whose clinicians requested remdesivir through the compassionate use program. The intended remdesivir treatment course was 10 days (200 mg on day 1, followed by 100 mg for days 2–10, given intravenously).

Results

Nineteen of 86 women delivered before their first dose and were reclassified as immediate “postpartum” (median postpartum day 1 [range, 0–3]). At baseline, 40% of pregnant women (median gestational age, 28 weeks) required invasive ventilation, in contrast to 95% of postpartum women (median gestational age at delivery 30 weeks). By day 28 of follow-up, the level of oxygen requirement decreased in 96% and 89% of pregnant and postpartum women, respectively. Among pregnant women, 93% of those on mechanical ventilation were extubated, 93% recovered, and 90% were discharged. Among postpartum women, 89% were extubated, 89% recovered, and 84% were discharged. Remdesivir was well tolerated, with a low incidence of serious adverse events (AEs) (16%). Most AEs were related to pregnancy and underlying disease; most laboratory abnormalities were grade 1 or 2. There was 1 maternal death attributed to underlying disease and no neonatal deaths.

Conclusions

Among 86 pregnant and postpartum women with severe COVID-19 who received compassionate-use remdesivir, recovery rates were high, with a low rate of serious AEs.

Corticosteroids in the Management of Pregnant Patients With Coronavirus Disease (COVID-19)

Recent evidence supports the use of an early, short course of glucocorticoids in patients with COVID-19 who require mechanical ventilation or oxygen support. As the number of coronavirus disease 2019 (COVID-19) cases continues to increase, the number of pregnant women with the disease is very likely to increase as well. Because pregnant women are at increased risk for hospitalization, intensive care unit admission, and mechanical ventilation support, obstetricians will be facing the dilemma of initiating maternal corticosteroid therapy while weighing its potential adverse effects on the fetus (or neonate if the patient is postpartum and breastfeeding). Our objective is to summarize the current evidence supporting steroid therapy in the management of patients with acute respiratory distress syndrome and COVID-19 and to elaborate on key modifications for the pregnant patient.

Severity of COVID-19 in pregnancy: A review of current evidence

Coronavirus disease 19 (COVID-19) has recently emerged as a major threat to human health. Infections range from asymptomatic to severe (increased respiratory rate, hypoxia, significant lung involvement on imaging) or critical (multi-organ failure or dysfunction or respiratory failure requiring mechanical ventilation or high-flow nasal cannula). Current evidence suggests that pregnancy women are at increased risk of severe disease, specifically the need for hospitalization, ICU admission, and mechanical ventilation, and the already complex management of infection with an emerging pathogen may be further complicated by pregnancy. The goal of this review is to provide an overview of what is known about the clinical course of COVID-19 in pregnancy, drawing on (a) experience with other coronaviruses such as SARS and MERS, (b) knowledge of immunologic and physiologic changes in pregnancy and how these might impact infection with SARS-CoV-2, and (c) the current literature reporting outcomes in pregnant women with SARS-CoV-2. We also briefly summarize considerations in management of severe COVID-19 in pregnancy.

Pregnancy worsens the morbidity of COVID-19 and this effect becomes more prominent as pregnancy advances

Objective

To investigate pregnancy outcomes and compare the clinical characteristics of coronavirus 2019 (COVID-19) disease in pregnant and agematched non-pregnant women.

Materials and Methods

Hospital records of four tertiary care centers were reviewed retrospectively. The subjects comprised 188 pregnant patients and 799 non-pregnant women who were admitted to these hospitals.

Results

Pregnancy significantly affected the clinical severity of COVID-19 and this effect was more prominent in pregnant women at >20 weeks gestation (p<0.001). Rates of oxygen support (10.1% vs 4.8%; p≤0.001), intensive care unit admission (3.2% vs 0.6%; p=0.009), presence of fever (12.8% vs 4.4%; p<0.001), tachypnea (7.0% vs 2.4%; p=0.003) and tachycardia (16.0% vs 1.9%; p<0.001) were significantly more frequent in pregnant women compared with non-pregnant women. Pregnancy was strongly associated with the need for oxygen support [relative risk (RR), 2.125; 95% confidence interval (CI): 1.25-3.60] and admission to the intensive care unit (RR, 5.1; 95% CI: 1.57-16.53) compared with non-pregnant women. Some 14.4% of the pregnant women had co-morbidities. Sixty of the 188 pregnant women (31.9%) delivered during the Severe Acute Respiratory syndrome coronavirus-2 infection, 11 (18.3%) had vaginal deliveries and 49 (81.7%) were by cesarean section. Of these 60 deliveries, 40 (66.7%) were <37 weeks gestation.

Conclusion

Pregnancy worsens the morbidity of COVID-19 and this effect seems to increase as the pregnancy advances, but not the mortality rate.

Clinical characteristics, prognostic factors, and maternal and neonatal outcomes of SARS-CoV-2 infection among hospitalized pregnant women: A systematic review

BACKGROUND

Pregnant women represent a potentially high-risk population in the COVID-19 pandemic.

OBJECTIVE

To summarize clinical characteristics and outcomes among pregnant women hospitalized with COVID-19.

SEARCH STRATEGY

Relevant databases were searched up until May 29, 2020.

SELECTION CRITERIA

Case series/reports of hospitalized pregnant women with laboratory-confirmed COVID-19.

DATA COLLECTION AND ANALYSIS

PRISMA guidelines were followed. Methodologic quality was assessed via NIH assessment tools.

MAIN RESULTS

Overall, 63 observational studies of 637 women (84.6% in third trimester) with laboratory-confirmed SARS-CoV-2 infection were included. Most (76.5%) women experienced mild disease. Maternal fatality, stillbirth, and neonatal fatality rates were 1.6%, 1.4%, and 1.0%, respectively. Older age, obesity, diabetes mellitus, and raised serum D-dimer and interleukin-6 were predictive of poor outcomes. Overall, 33.7% of live births were preterm, of which half were iatrogenic among women with mild COVID-19 and no complications. Most women underwent cesarean despite lacking a clear indication. Eight (2.0%) neonates had positive nasopharyngeal swabs after delivery and developed chest infection within 48 hours.

CONCLUSIONS

Advanced gestation, maternal age, obesity, diabetes mellitus, and a combination of elevated D-dimer and interleukin-6 levels are predictive of poor pregnancy outcomes in COVID-19. The rate of iatrogenic preterm birth and cesarean delivery is high; vertical transmission may be possible but has not been proved.

COVID-19-related disease severity in pregnancy

The pandemic caused by COVID-19 is affecting populations and healthcare systems worldwide. As we gain experience managing COVID-19, more data become available on disease severity, course, and treatment in patients infected with the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). However, data in pregnancy remain limited. This narrative review of COVID-19 during pregnancy underscores key knowledge gaps in our understanding of the impact of this viral infection on reproductive health. Current data suggest that pregnant people have similar disease course and outcomes compared to nonpregnant people, with the majority experiencing mild disease; however, pregnant people may have increased risk of hospitalization and intensive care unit (ICU) admission. Among patients who develop severe and critical disease, major maternal morbidity and mortality have been described including cardiomyopathy, mechanical ventilation, extracorporeal membrane oxygenation, and death. Many questions remain regarding maternal severity of disease in COVID-19. Further research is needed to better understand disease course in pregnancy. Additionally, the inclusion of pregnant patients in therapeutic trials will provide vital data on treatment options for patients. As we continue to treat more patients affected by SARS-CoV-2, multidisciplinary care and continued research are both needed to achieve optimal outcomes for mother and fetus.

Infant Outcomes Following Maternal Infection with SARS-CoV-2: First Report from the PRIORITY Study

Infant outcomes after maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are not well described. In a prospective US registry of 263 infants, maternal SARS-CoV-2 status was not associated with birth weight, difficulty breathing, apnea, or upper or lower respiratory infection through 8 weeks of age.

Preserving Multidisciplinary Care Model and Patient Safety During Reopening of Ambulatory Cystic Fibrosis Clinic for Nonurgent Care: A Hybrid Telehealth Model

Introduction: The University of Virginia's (UVA's) adult cystic fibrosis (CF) program implemented a rapid and successful transition to telemedicine care mid-March of 2020 in response to the coronavirus disease 2019 (COVID-19) pandemic. In May 2020, the adult UVA CF program redesigned the care model to adjust to the reopening of ambulatory operations and introduced hybrid clinics. The goal remained to minimize person-to-person contacts for patients and care team members (CTMs) while ensuring patient access to quarterly, coproduced, synchronous, multidisciplinary CF care, similar to pre-COVID-19 era regular CF care. Methods: Using quality improvement tools, the UVA adult CF program created a standardized hybrid model of care for in-clinic visits, which included combined components of in-person and synchronous virtual interactions with members of the multidisciplinary team. Results: A total of 16 hybrid visits occurred between May 14 and June 11, 2020. All hybrid visits were multidisciplinary and fulfilled patient requests to see CTMs. All patients seen by hybrid encounter participated in coproduced agenda setting, underwent spirometry, and obtained blood work; 75% provided sputum for surveillance culture. Each hybrid visit type was attended by an average of four CTMs and amounted to 63 separate interactions. Of these interactions, 28 were completed virtually, reducing in-person contacts and personal protection equipment utilization by 44% compared with a fully in-person model of care. Conclusions: Combining in-person and telehealth components in a multidisciplinary CF care model reduces patient and staff interactions and personal protective equipment utilization. The hybrid model of in-person/remote combined care enables reliable access to biological data to support medical decision making while mitigating the risks of person-to-person contact for patients and staff.

COVID-19 Pandemic and Pregnancy in Kidney Disease

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is a rapidly spreading pandemic. Owing to changes in the immune system and respiratory physiology, pregnant women are vulnerable to severe viral pneumonia. We review the clinical course, pregnancy outcomes, and management of women with COVID-19 in pregnancy with a focus on those with kidney involvement. Current evidence does not show an increased risk of acquiring SARS-CoV-2 during pregnancy and the maternal course appears to be similar to nonpregnant patients. However, severe maternal disease can lead to complex management challenges and has shown to be associated with higher incidence of preterm and caesarean births. The risk of congenital infection with SARS-CoV-2 is not known. All neonates must be considered as high-risk contacts and should be screened at birth and isolated. Pregnant women should follow all measures to prevent SARS-CoV-2 exposure and this fear should not compromise antenatal care. Use of telemedicine, videoconferencing, and noninvasive fetal and maternal home monitoring devices should be encouraged. High-risk pregnant patients with comorbidities and COVID-19 require hospitalization and close monitoring. Pregnant women with COVID-19 and kidney disease are a high-risk group and should be managed by a multidisciplinary team approach including a nephrologist and neonatologist.

Remdesivir Treatment for Severe COVID-19 in Third-Trimester Pregnancy: Case Report and Management Discussion

We report a case of COVID-19 in third-trimester pregnancy, who required support in an intensive care unit and received remdesivir. After discharge, she had an uncomplicated vaginal delivery at term. COVID-19 in pregnancy may be managed without emergent delivery; a multispecialty team is critical in caring for these patients.

Clinical manifestations, risk factors, and maternal and perinatal outcomes of coronavirus disease 2019 in pregnancy: living systematic review and meta-analysis

OBJECTIVE

To determine the clinical manifestations, risk factors, and maternal and perinatal outcomes in pregnant and recently pregnant women with suspected or confirmed coronavirus disease 2019 (covid-19).

DESIGN

Living systematic review and meta-analysis.

DATA SOURCES

Medline, Embase, Cochrane database, WHO COVID-19 database, China National Knowledge Infrastructure (CNKI), and Wanfang databases from 1 December 2019 to 6 October 2020, along with preprint servers, social media, and reference lists.

STUDY SELECTION

Cohort studies reporting the rates, clinical manifestations (symptoms, laboratory and radiological findings), risk factors, and maternal and perinatal outcomes in pregnant and recently pregnant women with suspected or confirmed covid-19.

DATA EXTRACTION

At least two researchers independently extracted the data and assessed study quality. Random effects meta-analysis was performed, with estimates pooled as odds ratios and proportions with 95% confidence intervals. All analyses will be updated regularly.

RESULTS

192 studies were included. Overall, 10% (95% confidence interval 7% to 12%; 73 studies, 67 271 women) of pregnant and recently pregnant women attending or admitted to hospital for any reason were diagnosed as having suspected or confirmed covid-19. The most common clinical manifestations of covid-19 in pregnancy were fever (40%) and cough (41%). Compared with non-pregnant women of reproductive age, pregnant and recently pregnant women with covid-19 were less likely to have symptoms (odds ratio 0.28, 95% confidence interval 0.13 to 0.62; I2=42.9%) or report symptoms of fever (0.49, 0.38 to 0.63; I2=40.8%), dyspnoea (0.76, 0.67 to 0.85; I2=4.4%) and myalgia (0.53, 0.36 to 0.78; I2=59.4%). The odds of admission to an intensive care unit (odds ratio 2.13, 1.53 to 2.95; I2=71.2%), invasive ventilation (2.59, 2.28 to 2.94; I2=0%) and need for extra corporeal membrane oxygenation (2.02, 1.22 to 3.34; I2=0%) were higher in pregnant and recently pregnant than non-pregnant reproductive aged women. Overall, 339 pregnant women (0.02%, 59 studies, 41 664 women) with confirmed covid-19 died from any cause. Increased maternal age (odds ratio 1.83, 1.27 to 2.63; I2=43.4%), high body mass index (2.37, 1.83 to 3.07; I2=0%), any pre-existing maternal comorbidity (1.81, 1.49 to 2.20; I2=0%), chronic hypertension (2.0, 1.14 to 3.48; I2=0%), pre-existing diabetes (2.12, 1.62 to 2.78; I2=0%), and pre-eclampsia (4.21, 1.27 to 14.0; I2=0%) were associated with severe covid-19 in pregnancy. In pregnant women with covid-19, increased maternal age, high body mass index, non-white ethnicity, any pre-existing maternal comorbidity including chronic hypertension and diabetes, and pre-eclampsia were associated with serious complications such as admission to an intensive care unit, invasive ventilation and maternal death. Compared to pregnant women without covid-19, those with the disease had increased odds of maternal death (odds ratio 2.85, 1.08 to 7.52; I2=0%), of needing admission to the intensive care unit (18.58, 7.53 to 45.82; I2=0%), and of preterm birth (1.47, 1.14 to 1.91; I2=18.6%). The odds of admission to the neonatal intensive care unit (4.89, 1.87 to 12.81, I2=96.2%) were higher in babies born to mothers with covid-19 versus those without covid-19.

CONCLUSION

Pregnant and recently pregnant women with covid-19 attending or admitted to the hospitals for any reason are less likely to manifest symptoms such as fever, dyspnoea, and myalgia, and are more likely to be admitted to the intensive care unit or needing invasive ventilation than non-pregnant women of reproductive age. Pre-existing comorbidities, non-white ethnicity, chronic hypertension, pre-existing diabetes, high maternal age, and high body mass index are risk factors for severe covid-19 in pregnancy. Pregnant women with covid-19 versus without covid-19 are more likely to deliver preterm and could have an increased risk of maternal death and of being admitted to the intensive care unit. Their babies are more likely to be admitted to the neonatal unit.

What's Sex Got to Do With COVID-19? Gender-Based Differences in the Host Immune Response to Coronaviruses

The novel severe acute respiratory syndrome coronavirus 2, the cause of the coronavirus disease 2019 (COVID-19) pandemic, has ravaged the world, with over 22 million total cases and over 770,000 deaths worldwide as of August 18, 2020. While the elderly are most severely affected, implicating an age bias, a striking factor in the demographics of this deadly disease is the gender bias, with higher numbers of cases, greater disease severity, and higher death rates among men than women across the lifespan. While pre-existing comorbidities and social, behavioral, and lifestyle factors contribute to this bias, biological factors underlying the host immune response may be crucial contributors. Women mount stronger immune responses to infections and vaccinations and outlive men. Sex-based biological factors underlying the immune response are therefore important determinants of susceptibility to infections, disease outcomes, and mortality. Despite this, gender is a profoundly understudied and often overlooked variable in research related to the immune response and infectious diseases, and it is largely ignored in drug and vaccine clinical trials. Understanding these factors will not only help better understand the pathogenesis of COVID-19, but it will also guide the design of effective therapies and vaccine strategies for gender-based personalized medicine. This review focuses on sex-based differences in genes, sex hormones, and the microbiome underlying the host immune response and their relevance to infections with a focus on coronaviruses.

Rapid establishment of a COVID-19 perinatal biorepository: early lessons from the first 100 women enrolled

BACKGROUND

Collection of biospecimens is a critical first step to understanding the impact of COVID-19 on pregnant women and newborns - vulnerable populations that are challenging to enroll and at risk of exclusion from research. We describe the establishment of a COVID-19 perinatal biorepository, the unique challenges imposed by the COVID-19 pandemic, and strategies used to overcome them.

METHODS

A transdisciplinary approach was developed to maximize the enrollment of pregnant women and their newborns into a COVID-19 prospective cohort and tissue biorepository, established on March 19, 2020 at Massachusetts General Hospital (MGH). The first SARS-CoV-2 positive pregnant woman was enrolled on April 2, and enrollment was expanded to SARS-CoV-2 negative controls on April 20. A unified enrollment strategy with a single consent process for pregnant women and newborns was implemented on May 4. SARS-CoV-2 status was determined by viral detection on RT-PCR of a nasopharyngeal swab. Wide-ranging and pregnancy-specific samples were collected from maternal participants during pregnancy and postpartum. Newborn samples were collected during the initial hospitalization.

RESULTS

Between April 2 and June 9, 100 women and 78 newborns were enrolled in the MGH COVID-19 biorepository. The rate of dyad enrollment and number of samples collected per woman significantly increased after changes to enrollment strategy (from 5 to over 8 dyads/week, P < 0.0001, and from 7 to 9 samples, P < 0.01). The number of samples collected per woman was higher in SARS-CoV-2 negative than positive women (9 vs 7 samples, P = 0.0007). The highest sample yield was for placenta (96%), umbilical cord blood (93%), urine (99%), and maternal blood (91%). The lowest-yield sample types were maternal stool (30%) and breastmilk (22%). Of the 61 delivered women who also enrolled their newborns, fewer women agreed to neonatal blood compared to cord blood (39 vs 58, P < 0.0001).

CONCLUSIONS

Establishing a COVID-19 perinatal biorepository required patient advocacy, transdisciplinary collaboration and creative solutions to unique challenges. This biorepository is unique in its comprehensive sample collection and the inclusion of a control population. It serves as an important resource for research into the impact of COVID-19 on pregnant women and newborns and provides lessons for future biorepository efforts.

Pathophysiology of COVID-19: Mechanisms Underlying Disease Severity and Progression

The global epidemiology of coronavirus disease 2019 (COVID-19) suggests a wide spectrum of clinical severity, ranging from asymptomatic to fatal. Although the clinical and laboratory characteristics of COVID-19 patients have been well characterized, the pathophysiological mechanisms underlying disease severity and progression remain unclear. This review highlights key mechanisms that have been proposed to contribute to COVID-19 progression from viral entry to multisystem organ failure, as well as the central role of the immune response in successful viral clearance or progression to death.

COVID-19 and the Antipoverty Vaccines

The number of global COVID19 cases has just exceeded 15 million, and there is mounting evidence for a devastating economic impact from this illness. Although COVID19 affected primarily China, Europe, and North America during the first half of 2020, now this disease is accelerating in the resource-poor nations of the Global South. Across Latin America, South Asia, and Africa, COVID19 is expected to push up to 100 million people into extreme poverty, eroding many of the economic gains achieved over the last five years. COVID19 vaccines will be required to help control the pandemic, especially in low- and middle-income nations. These will have important health benefits, but might also prevent further economic devastation. The term “antipoverty vaccines” has been used to refer to vaccines to prevent neglected tropical diseases that affect worker productivity, child development, and the health of girls and women. COVID19 vaccines could also become important antipoverty technologies provided we find ways to scale and distribute them as affordable vaccines. Two vaccines now being accelerated for global health include whole inactivated virus and recombinant protein vaccines. These might become essential tools for combating global poverty.

Considerations for Pregnant Dental and Health Care Workers amid COVID-19

INTRODUCTION

Coronavirus disease 2019 (COVID-19) is a highly contagious disease that quickly reached pandemic levels. Over 5 million COVID-19 cases and approximately 330,000 deaths have been recorded worldwide. Transmission is primarily spread through direct, indirect (through contaminated objects or surfaces), or close contact with infected people via respiratory droplets, the mouth, and/or nose secretions. Health care professionals (HCPs), including dental HCPs, are recognized to be at considerably high risk for infection due to the close proximity to patients and aerosol-generating procedures. During pregnancy, HCPs may be at even higher risk since pregnancy substantially increases the susceptibility to infectious diseases.

OBJECTIVES

Here, we present the posed risks and potential effects of COVID-19 on maternal and fetal health. Current prevention and management strategies for COVID-19 on pregnant dental and HCPs are also discussed.

RESULTS

Significant progress is being made in understanding the pathogenesis and clinical consequences of COVID-19. Pregnant women are affected more adversely with viral illnesses, although evidence of vertical transmission of COVID-19 is controversial. Based on the presence of atypical symptoms, the significant numbers of asymptomatic individuals who are COVID-19 positive, and the high susceptibility to viral diseases observed in pregnant women, recommendations have been put forth to limit the exposure of COVID-19-positive or even suspected cases to pregnant HCPs, and these are likely to evolve as new information becomes available.

CONCLUSION

Pregnant HCPs require extra caution: not only are they considered a high-risk population, but their work at the frontline in a pandemic may expose them to additional risks. Complete awareness of the effects of COVID-19 on maternal and fetal/infant health, as well as prevention and management guidelines for pregnant HCPs, will allow for a safer work environment. Health care institutional policies aimed at protecting pregnant HCPs should consider avoiding their assignment as first responders, especially if equally trained staff are available.

KNOWLEDGE TRANSFER STATEMENT

Dental and health care professionals can use the information in this review to improve their awareness of COVID-19 risks, signs, and symptoms and the associated effects on the health of pregnant health care professionals and their unborn/newborn children.

Practical considerations for pregnant women with diabetes and severe acute respiratory syndrome coronavirus 2 infection

Epidemiologic data available so far suggest that individuals with diabetes, especially when not well controlled, are at a greater risk than the general population for severe acute respiratory syndrome coronavirus 2 morbidity such as acute respiratory distress syndrome, multiorgan failure, and mortality. Given the significant correlation between severity of coronavirus disease 2019 and diabetes mellitus and the lack of pregnancy-specific recommendations, we aim to provide some guidance and practical recommendations for the management of diabetes in pregnant women during the pandemic, especially for general obstetricians-gynecologists and nonobstetricians taking care of these patients.

Osteopathic Considerations for the Pregnant Patient with COVID-19

In any given year, approximately 130 million babies are born worldwide. Previous research has shown that pregnant women may be more severely affected and vulnerable to contracting emerging infections, making them a particularly high-risk population. Therefore, special considerations should be given to treatment methods for pregnant women with COVID-19. In this narrative review, the authors evaluate scholarly journal articles and electronic databases to determine what is known about the pathophysiology of COVID-19 in pregnancy and the associated mortality rate. Osteopathic manipulative treatment techniques to mitigate the underlying pathology were identified, and modifications for use in pregnancy and the critical care setting are described.

Review of maternal COVID-19 infection: considerations for the pediatric ophthalmologist

With the increasing number of COVID-19 cases in the United States, more data is being reported on transmission, symptomatology, clinical course, and treatment of the virus. Research has focused on the trends and unique characteristics in at-risk populations, including pregnant women. This report summarizes the current data on considerations in pregnancy and postpartum period for mother and neonate to elucidate potential transmission risks for pediatric ophthalmologists.

The tragedy of COVID-19 in Brazil: 124 maternal deaths and counting

At the time of writing 124 pregnant or postpartum women in Brazil have died due to COVID‐19 (representing a mortality rate of 12.7%), a figure that currently surpasses the total number of COVID‐19‐related maternal deaths reported throughout the rest of the world.

Community Pharmacists' Contributions to Disease Management During the COVID-19 Pandemic

Community pharmacists assist patients to manage disease and prevent complications. Despite the enormous challenge the coronavirus disease 2019 (COVID-19) pandemic has dealt to the health care system, community pharmacists have maintained the delivery of critical health services to communities, including those most at risk for COVID-19. Community pharmacists are in a key position to deliver priority pandemic responses including point-of-care testing for chronic disease management, vaccinations, and COVID-19 testing.

Impact of COVID-19 on the Perinatal Period Through a Biopsychosocial Systemic Framework

The perinatal period involves major developmental transitions which can be conceptualized through a biopsychosocial (BPS; Engel in Science 196:129–136, 1977, 10.1126/science.847460, in The American Journal of Psychiatry 137:535–544, 1980, 10.1176/ajp.137.5.535), systemic (von Bertalanffy, General system theory: Foundations, development, applications, George Braziller, New York, 1968) framework. Thus, no one domain of health in the perinatal period can be understood without exploring how the other domains are both impacted by and impacting the others. As a result of COVID-19, popular media is paying special attention to the biomedical domain of women in the perinatal period as it relates to health outcomes and changes in perinatal healthcare policies; however, considerably less attention is being paid to the other BPS health domains and systemic impacts. This paper will outline U.S. changes in healthcare as a result of the COVID-19 pandemic for individuals, couples, and families within the perinatal period (i.e., family planning and conception, prenatal, labor and delivery, and postpartum) and explore the unique psychosocial, systemic impacts. Recommendations for care, including telehealth and virtual support options, and future directions for research will be provided.
