A Case Report of Neonatal 2019 Coronavirus Disease in China

Obstetrics and Neonatal Outcomes in Pregnant Women with COVID-19: A Systematic Review

BACKGROUND

Considering that the obstetricians and pediatricians need to comprehensive information about the obstetric and neonatal effect of COVID-19, this review study was conducted to investigate the impact of COVID-19 on obstetrics and neonatal outcomes.

METHODS

In this systematic review the international search databases following PubMed, Web of Science, Scopus, ProQuest and Embase and Google scholar were searched. All articles were reviewed by two independent researchers until 10 April 2020. After quality assessment of included studies the finding reported in 2 sections obstetrics and neonatal outcomes.

RESULTS

The sixteen studies with a sample size of 123 pregnant women with a definitive diagnosis of COVID-19 and their neonates were evaluated. The range of gestational age was 25-40 weeks. There was no death associated with COVID-19 in pregnant women. The obstetric outcomes in pregnant women with COVID-19 include decreased fetal movement, intrauterine fetal distress, anemia, PROM, preterm labor, Multiple Organ Dysfunction Syndrome (MODS) and etc. The most common delivery mode in women affect with COVID-19 was cesarean section. Expect for one case with MODS, in the majority of the studies reviewed, no severe morbidity or mortality occurred. The neonatal outcomes were stillbirth, prematurity, asphyxia, fetal distress, low birth weight, small for gestational age, large for gestational age, multiple organ dysfunction syndrome, disseminated intravascular coagulation and neonatal death. In addition, five neonates born to mothers with COVID-19 were positive for SARS-CoV-2. However, the studies report these outcomes but the exact causes of theme are not known.

CONCLUSION

In this systematic review, we summarize the diverse results of studies about the obstetrics and neonatal outcomes following COVID-19. This infection may cause negative outcomes in both mothers and neonates. However, there were evidence about neonate infected with COVID-19, but there is controversial information about the vertical transmission of COVID-19.

COVID-19 in babies: Knowledge for neonatal care

Infection is a leading cause of death worldwide in babies under one month of age who are more susceptible to sepsis due to immature host defence mechanisms. Usually, babies may become acutely unwell from infective pathogens due to specific differences in their respiratory and immune systems. However, with the COVID-19 virus, the focus of this paper, it appears that the neonatal population is not significantly affected in the same way as adults. That said, knowledge about this novel virus is rapidly emerging. Therefore, it is vital that neonatal nurses, midwives and other healthcare professionals are adequately informed and educated about the potential impact on neonatal practice. This review paper draws upon key findings and themes from a selection of recent literature to provide an overview of current knowledge on COVID-19 and the implications for care within the neonatal field. The discussion focuses on the nature of COVID-19, its pathophysiology and transmission relevant to maternal and neonatal care. This is followed by implications for practice; namely, maternal issues, the importance of human breast milk, neonatal care relating to parenting and specific management before a final review of the current World Health Organization guidance.

Chest computed tomography (CT) features in children with reverse transcription-polymerase chain reaction (RT-PCR)-confirmed COVID-19: A systematic review

To describe the chest CT features reported in children with confirmed COVID-19 infection, published in English literature. A systematic review was completed on PubMed, Embase and Scopus databases on the 1st of June 2020 using the PICO strategy. The NIH Quality Assessment Tool was used to assess the quality of the selected articles. The systematic review was evaluated by Case Series Studies and the Preferred Reporting Items for a Systematic Review and Meta-analysis of Diagnostic Test Accuracy Studies (PRISMA). The extracted data were assessed and compared with those reported in the adult population. Seventy-two articles were retrieved from the database search and screened by the title, abstract and keywords. Eleven articles were deemed eligible for full-text assessment. Nine articles were included for the data extraction and in the final analysis. Chest CT features in children with COVID-19 differ from those in adults. 'Ground-grass opacities' (GGOs) are the most commonly described abnormalities, but closely followed by a combination of GGO and consolidation, not usual in adults. Children tend to have a more variable involvement than the subpleural and posterior and basal topography described in adults. Interlobular thickening and air bronchogram found in adults with COVID-19 are not frequent in children. Pulmonary embolism reported in up to 30% of adults has not been yet reported in children. Original articles describing chest CT features in children with COVID-19 in the English literature are limited to small populations of Chinese children. Chest CT imaging features are very diverse across the selected studies and globally different from those reported in adults. Data from children of different countries would provide a more comprehensive description of chest CT features in children with COVID-19.

Consistent localization of SARS-CoV-2 spike glycoprotein and ACE2 over TMPRSS2 predominance in placental villi of 15 COVID-19 positive maternal-fetal dyads

INTRODUCTION

While the COVID-19 pandemic continues to have a significant global health impact, rates of maternal to infant vertical transmission remain low (<5%). Parenchymal changes of placentas from COVID-19 infected mothers have been reported by several groups, but the localization and relative abundance of SARS-CoV-2 viral proteins and cellular entry machinery has not been fully characterized within larger placental tissue cohorts.

METHODS

An extended placental tissue cohort including samples from 15 COVID-19 positive maternal-fetal dyads (with n = 5 cases with evidence of fetal transmission) in comparison with 10 contemporary COVID-19 negative controls. Using comparative immunofluorescence, we examined the localization and relative tissue abundance of SARS-CoV2 spike glycoprotein (CoV2 SP) along with the co-localization of two SARS-CoV2 viral entry proteins angiotensin-converting enzyme 2 (ACE2) and transmembrane serine protease 2 (TMPRSS2).

RESULTS/CONCLUSIONS

CoV2 SP was present within the villous placenta in COVID-19 positive pregnancies with and without evidence of fetal transmission. We further identified the predominance of ACE2 expression in comparison with TMPRSS2. Importantly, both CoV2 SP and ACE2 expression consistently localized primarily within the outer syncytiotrophoblast layer placental villi, a key physiologic interface between mother and fetus. Overall this study provides an important basis for the ongoing evaluation of SARS-CoV-2 physiology in pregnancy and highlights the importance of the placenta as a key source of primary human tissue for ongoing diagnostic and therapeutic research efforts to reduce the global burden of COVID-19.

The clinical course of SARS-CoV-2 positive neonates

The COVID-19 pneumonia was firstly reported in Wuhan, China, in December 2019. The disease had a rapid spread all over the word becoming an international public health emergency. Limited data were available on COVID-19 positive neonates. We reviewed relevant literature to understand the clinical course of disease and transmission routes in affected neonates. The aim of the study was evaluating the clinical course and prognosis of SARS-CoV-2 positive neonates. Based on current literature, the hypothesis of vertical transmission of SARS-CoV-2, though conceivable, remains unproven. A research conducted on PubMed database from December 2019 to April 27, 2020 revealed that were reported 25 neonates affected by SARS-CoV-2. Main symptoms were fever, cough, or shortness of breath but often these neonates did not show other symptoms during length stay in hospital. No deaths occurred.

SARS-CoV-2 and human milk: What is the evidence?

The novel coronavirus SARS-CoV-2 has emerged as one of the most compelling and concerning public health challenges of our time. To address the myriad issues generated by this pandemic, an interdisciplinary breadth of research, clinical and public health communities has rapidly engaged to collectively find answers and solutions. One area of active inquiry is understanding the mode(s) of SARS-CoV-2 transmission. Although respiratory droplets are a known mechanism of transmission, other mechanisms are likely. Of particular importance to global health is the possibility of vertical transmission from infected mothers to infants through breastfeeding or consumption of human milk. However, there is limited published literature related to vertical transmission of any human coronaviruses (including SARS-CoV-2) via human milk and/or breastfeeding. Results of the literature search reported here (finalized on 17 April 2020) revealed a single study providing some evidence of vertical transmission of human coronavirus 229E; a single study evaluating presence of SARS-CoV in human milk (it was negative); and no published data on MERS-CoV and human milk. We identified 13 studies reporting human milk tested for SARS-CoV-2; one study (a non-peer-reviewed preprint) detected the virus in one milk sample, and another study detected SARS-CoV-2 specific IgG in milk. Importantly, none of the studies on coronaviruses and human milk report validation of their collection and analytical methods for use in human milk. These reports are evaluated here, and their implications related to the possibility of vertical transmission of coronaviruses (in particular, SARS-CoV-2) during breastfeeding are discussed.

Concerns of women regarding pregnancy and childbirth during the COVID-19 pandemic

OBJECTIVE

Better understand knowledge, attitudes and practices of pregnant women and mothers of infants around coronavirus disease 2019 (COVID-19).

METHODS

A 58-item electronic survey was distributed to pregnant and postpartum women (infants <12 months) who were >15 years, English-speaking and enrolled in prenatal programs. Data is summarized using central tendency, frequencies and nonparametric statistics.

RESULTS

Of 114 (51 % response rate) participants, 82.5 % reported negative changes in mental status measures (e.g. stress, anxious thoughts, changes in sleep patterns). All reported risk-reduction behavior changes (e.g. handwashing/use of sanitizer, social distancing). Significant changes were reported in employment and financial status due to the pandemic. Increases in alcohol consumption among postpartum women were also reported. Few reported changes in prenatal, infant or postpartum healthcare access.

CONCLUSION

This study provides initial insight into the knowledge, attitudes and practices of pregnant and postpartum women during the COVID-19 pandemic. This study is limited as participants represent a single Midwest community and social desirability response bias may have impacted responses. However, results may inform future interventions to support pregnant women and mothers of infants during pandemics.

PRACTICE IMPLICATIONS

Providers should consider the impact of such events on mental status, access to resources and changes in behaviors.

Clinical manifestations and maternal and perinatal outcomes with COVID-19

Coronavirus disease 2019 (COVID-19) is a novel type of highly contagious pneumonia caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). As the COVID-19 outbreak unfolds, more and more pregnant women are infected with SARS-CoV-2, concerns have been raised about its clinical manifestations in pregnancy and the potential risk of vertical transmission from mother to fetus in pregnant women. Hence, in this review, we summarize the latest research progress related to COVID-19 epidemiology and the reported data of pregnant women with COVID-19 and discuss the clinical manifestations, treatments, maternal and perinatal outcomes, and intrauterine vertical transmission potential of such virus. Reported data suggest that symptoms in pregnant women are similar to those in other populations and that there is no evidence of vertical transmission from mother to child. In the meantime, considering the good prognosis of most of the infected mothers and infants and absence of serious obstetric complications in pregnant women with COVID-19, it is not recommended to give birth as soon as possible, and it is necessary to extend the gestational period reasonably.

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.

Clinical Characteristics of Asymptomatic and Symptomatic Pediatric Coronavirus Disease 2019 (COVID-19): A Systematic Review

Background and objectives: Characterization of pediatric coronavirus disease 2019 (COVID-19) is necessary to control the pandemic, as asymptomatic or mildly infected children may act as carriers. To date, there are limited reports describing differences in clinical, laboratory, and radiological characteristics between asymptomatic and symptomatic infection, and between younger and older pediatric patients. The objective of this study is to compare characteristics among: (1) asymptomatic versus symptomatic and (2) less than 10 versus greater or equal to 10 years old pediatric COVID-19 patients. Materials and Methods: We searched for all terms related to pediatric COVID-19 in electronic databases (Embase, Medline, PubMed, and Web of Science) for articles from January 2020. This protocol followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Results: Eligible study designs included case reports and series, while we excluded comments/letters, reviews, and literature not written in English. Initially, 817 articles were identified. Forty-three articles encompassing 158 confirmed pediatric COVID-19 cases were included in the final analyses. Lymphocytosis and high CRP were associated with symptomatic infection. Abnormal chest CT more accurately detected asymptomatic COVID-19 in older patients than in younger ones, but clinical characteristics were similar between older and younger patients. Conclusions: Chest CT scan findings are untrustworthy in younger children with COVID-19 as compared with clinical findings, or significant differences in findings between asymptomatic to symptomatic children. Further studies evaluating pediatric COVID-19 could contribute to potential therapeutic interventions and preventive strategies to limit spreading.

The effect of coronavirus infection (SARS-CoV-2, MERS-CoV, and SARS-CoV) during pregnancy and the possibility of vertical maternal-fetal transmission: a systematic review and meta-analysis

BACKGROUND

Coronavirus is challenging the global health care system from time to time. The pregnant state, with alterations in hormone levels and decreased lung volumes due to a gravid uterus and slightly immunocompromised state may predispose patients to a more rapidly deteriorating clinical course and can get a greater risk of harm for both the mother and fetus. Therefore, this systematic review was aimed to assess the effect of coronavirus infection (SARS-CoV-2, MERS-CoV, and SARS-CoV) during pregnancy and its possibility of vertical maternal-fetal transmission.

METHODS

A systematic search was conducted on PubMed, Web of Science, Embase, Google Scholar and the Cochrane Library until the end of April. All authors independently extracted all necessary data using excel spreadsheet form. Only published articles with fully accessible data on pregnant women infected with SARS-CoV, MARS-CoV, and SARS-CoV-2 were included. Data on clinical manifestations, maternal and perinatal outcomes were extracted and analyzed.

RESULT

Out of 879 articles reviewed, 39 studies involving 1316 pregnant women were included. The most common clinical features were fever, cough, and myalgia with prevalence ranging from 30 to 97%, while lymphocytopenia and C-reactive protein were the most common abnormal laboratory findings (55-100%). Pneumonia was the most diagnosed clinical symptom of COVID-19 and non-COVID-19 infection with prevalence ranged from 71 to 89%. Bilateral pneumonia (57.9%) and ground-glass opacity (65.8%) were the most common CT imaging reported. The most common treatment options used were hydroxychloroquine (79.7%), ribavirin (65.2%), and oxygen therapy (78.8%). Regarding maternal outcome, the rate of preterm birth < 37 weeks of gestation was 14.3%, preeclampsia (5.9%), miscarriage (14.5%, preterm premature rupture of membranes (9.2%) and fetal growth restriction (2.8%). From the total coronavirus infected pregnant women, 56.9% delivered by cesarean, 31.3% admitted to ICU, while 2.7% were died. Among the perinatal outcomes, fetal distress rated (26.5%), neonatal asphyxia rated (1.4%). Only, 1.2% of neonates had apgar score < 7 at 5 min. Neonate admitted to ICU was rated 11.3%, while the rate of perinatal death was 2.2%. In the current review, none of the studies reported transmission of CoV from the mother to the fetus in utero during the study period.

CONCLUSION

Coronavirus infection is more likely to affect pregnant women. Respiratory infectious diseases have demonstrated an increased risk of adverse maternal obstetrical complications than the general population due to physiological changes occurred during pregnancy. None of the studies reported transmission of CoV from the mother to the fetus in utero, which may be due to a very low expression of angiotensin-converting enzyme-2 in early maternal-fetal interface cells.

Clinical characteristics of acute respiratory syndrome with SARS-CoV-2 infection in children in South China

BACKGROUND

A retrospective study was conducted to summarize the clinical information of childhood infections during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic.

METHODS

Children with SARS-CoV-2 infection in 11 hospitals from three provinces of South China were included in the study. Clinical information was collected and compared with children and adults infected by SARS-CoV-2 in Wuhan.

RESULTS

In total, 52 children were enrolled, including 28 boys. The median age was 9 years (interquartile range [IQR], 4-12); 44.2% cases were of clustered occurrences, 40.4% patients had fever, 48.1% had cough, and 46.2% had a high lymphocyte count. No abnormalities were found in the liver and kidney function. Also, 82.7% of patients received antiviral therapy, but such therapy did not shorten the time to virus negativity or hospital stay (P = .082). The time to virus negativity was 12.0 days (IQR, 8.0-16.8) and hospital stay was 14.5 days (IQR, 10.3-17.9). Compared with reports in Wuhan, there were more acute upper respiratory tract infection (AURTI) and fewer pneumonia cases (P = .000). Compared with the non-ICU adult COVID-19 in Wuhan, these children's diseases were relatively mild, with fewer complications.

CONCLUSIONS

Children with SARS-CoV-2 infection had a mild fever, lymphocyte elevation was more common than reduction, and antiviral treatment had no obvious effect. The overall clinical manifestations were mild, and the prognosis was good.

Clinical and immunologic features among COVID-19-affected mother-infant pairs: antibodies to SARS-CoV-2 detected in breast milk

The coronavirus disease 2019 (COVID-19) pandemic remains threatening to women and children, but clinical evidence regarding women during pregnancy, puerperium and lactation is limited. We assessed clinical and immunologic features of and breastfeeding advice provided to mother–infant pairs. This observational analysis was conducted in a tertiary-care centre in Wuhan, China. Pregnant patients with laboratory-confirmed COVID-19 who delivered during hospitalization were enrolled. Clinical characteristics and serial specimens of the mother–infant pairs were examined, supplemented with follow-ups regarding recovery and breastfeeding. Fourteen pregnant patients had live births and recovered well; four patients continued breastfeeding while taking precautions. No neonatal infections were observed. No infants developed COVID-19 during breastfeeding. Common maternal symptoms were fever (11/14, 78.1%) and cough (6/14, 42.9%). A pregnancy-specific symptom was abnormal foetal movement, which was noticed by three patients (21.4%). The mean virus shedding time was 9 days (standard deviation, 6 days; range, 1–22 days). The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome was not detected in breast milk or maternal vaginal secretions. Immunologic assay revealed seroconversion of IgM on day 8 after onset and IgG on day 28. Both IgM and IgG antibodies to SARS-CoV-2 were detected in breast milk, cord blood and neonatal serum. The study results suggest that passive acquisition of antibodies against SARS-CoV-2 is available by ingesting breast milk. Breastfeeding has a low risk of transmitting SARS-CoV-2 or escalating maternal disease, so continuing breastfeeding with prudent precautions is encouraged.

Comorbidities, clinical signs and symptoms, laboratory findings, imaging features, treatment strategies, and outcomes in adult and pediatric patients with COVID-19: A systematic review and meta-analysis

INTRODUCTION

Since December 2019, a novel coronavirus (SARS-CoV-2) has triggered a world-wide pandemic with an enormous medical and societal-economic toll. Thus, our aim was to gather all available information regarding comorbidities, clinical signs and symptoms, outcomes, laboratory findings, imaging features, and treatments in patients with coronavirus disease 2019 (COVID-19).

METHODS

EMBASE, PubMed/Medline, Scopus, and Web of Science were searched for studies published in any language between December 1st, 2019 and March 28th, 2020. Original studies were included if the exposure of interest was an infection with SARS-CoV-2 or confirmed COVID-19. The primary outcome was the risk ratio of comorbidities, clinical signs and symptoms, laboratory findings, imaging features, treatments, outcomes, and complications associated with COVID-19 morbidity and mortality. We performed random-effects pairwise meta-analyses for proportions and relative risks, I2, T2, and Cochrane Q, sensitivity analyses, and assessed publication bias.

RESULTS

148 studies met the inclusion criteria for the systematic review and meta-analysis with 12'149 patients (5'739 female) and a median age of 47.0 [35.0-64.6] years. 617 patients died from COVID-19 and its complication. 297 patients were reported as asymptomatic. Older age (SMD: 1.25 [0.78-1.72]; p < 0.001), being male (RR = 1.32 [1.13-1.54], p = 0.005) and pre-existing comorbidity (RR = 1.69 [1.48-1.94]; p < 0.001) were identified as risk factors of in-hospital mortality. The heterogeneity between studies varied substantially (I2; range: 1.5-98.2%). Publication bias was only found in eight studies (Egger's test: p < 0.05).

CONCLUSIONS

Our meta-analyses revealed important risk factors that are associated with severity and mortality of COVID-19.

A Systematic Review of Treatment and Outcomes of Pregnant Women With COVID-19-A Call for Clinical Trials

BACKGROUND

Data pertaining to COVID-19 in pregnancy are limited; to better inform clinicians, we collated data from COVID-19 cases during pregnancy and summarized clinical trials enrolling this population.

METHODS

We performed a systematic literature review of PubMed/MEDLINE to identify cases of COVID-19 in pregnancy or the postpartum period and associated outcomes. We then evaluated the proportion of COVID-19 clinical trials (from ClinicalTrials.gov) excluding pregnant or breastfeeding persons (both through June 29, 2020).

RESULTS

We identified 11 308 published cases of COVID-19 during pregnancy. Of those reporting disease severity, 21% (416/1999) were severe/critical. Maternal and neonatal survival were reassuring (98% [10 437/10 597] and 99% [1155/1163], respectively). Neonatal disease was rare, with only 41 possible cases of infection reported in the literature. Of 2351 ongoing COVID-19 therapeutic clinical trials, 1282 were enrolling persons of reproductive age and 65% (829/1282) excluded pregnant persons. Pregnancy was an exclusion criterion for 69% (75/109) of chloroquine/hydroxychloroquine, 80% (28/35) of lopinavir/ritonavir, and 48% (44/91) of convalescent plasma studies. We identified 48 actively recruiting or completed drug trials reporting inclusion of this population.

CONCLUSIONS

There are limited published reports of COVID-19 in pregnancy despite more than 14 million cases worldwide. To date, clinical outcomes appear reassuring, but data related to important long-term outcomes are missing or not yet reported. The large number of clinical trials excluding pregnant persons, despite interventions with safety data in pregnancy, is concerning. In addition to observational cohort studies, pregnancy-specific adaptive clinical trials could be designed to identify safe and effective treatments.

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.

Clinical Features and Management of the Disease Caused by New Coronaviral Infection (COVID-19) in Children. Version 2

The Ministry of Health of the Russian Federation jointly with professional association and experts in the field of pediatrics, infectious diseases and resuscitation has revised guidelines “Clinical Features and Management of the Disease Caused by New Coronaviral Infection (COVID-19) in Children” in order to provide the child population with effective medical care during the pandemic of the new coronaviral infection. The practical experience of specialists from various countries was considered during the development of this document. Special attention should be given to the evidence base of the presented data, as well as to the efficiency and safety issues of medications used in treatment of coronaviral infection and its complications. The authors highlight the problems of prevention, diagnostics and management of pathological conditions caused by COVID-19 in the article according to the presented guidelines. Patient’s management is presented depending on the age and severity of the disease itself. The therapy is considered with regard to etiological, pathogenetic and symptom focus.

Clinical features of neonates born to mothers with coronavirus disease-2019: A systematic review of 105 neonates

Background

Despite the increasingly recognized impact of novel coronavirus disease (COVID-19), caused by severe acute respiratory syndrome (SARS) coronavirus 2 (SARS-CoV-2), on many aspects of health in adults and children, its effects on neonates born to infected mothers remain unclear. We conducted this study to investigate the outcomes of neonates born to mothers with COVID-19.

Methods

We searched the medical databases from inception to March 31, 2020 to perform a systematic review of outcomes in neonates born to mothers with COVID-19. Data were pooled using a random effects regression model. Primary and secondary outcomes were neonatal clinical outcomes and infectious status, respectively.

Results

Fourteen studies involving 105 neonates fulfilling the study criteria were identified. The rates of preterm neonates and those small for gestational age (SGA) were 25 (23.8%) and 10 (11.2%), respectively. Among 91 neonates who were tested, 8 (8.8%) were positive for nucleic acids or antibodies for SARS-CoV-2. Additionally, 28 (26.7%) of the neonates were symptomatic and two test-negative neonates died, including one stillbirth. Between test-positive and test-negative groups, the rates of SGA, preterm delivery, duration between maternal symptom onset and delivery, and perinatal complication were not significantly different; but the rate of symptomatic after birth reached significant difference (62.5% vs 20.5%, p = 0.008).

Conclusions

Most neonates born to infected mothers had favorable outcomes. Although direct evidences of intrauterine infection were scarce, the risk of intrauterine infection should be considered based on a positive test in 8.8% of the neonates. Symptomatic neonates born to infected mothers should receive tests for SARS-CoV-2 to initiate appropriate treatment and quarantine. Further studies are warranted to assess the outcomes of COVID-19 in neonates.

COVID-19 (Coronavirus Disease 2019): A New Coronavirus Disease

Coronavirus disease 2019 (COVID-19) is a type of viral pneumonia with an uncommon outbreak in Wuhan, China, in December 2019, which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV2). SARS-CoV-2 is extremely contagious and has resulted in a fast pandemic of COVID-19. Currently, COVID-19 is on the rise around the world, and it poses a severe threat to public health around the world. This review provides an overview about the COVID-19 virus to increase public awareness and understanding of the virus and its consequences in terms of history, epidemiology, structure, genome, clinical symptoms, diagnosis, prevention, and treatment.

Spectrum of neonatal COVID-19 in Iran: 19 infants with SARS-CoV-2 perinatal infections with varying test results, clinical findings and outcomes

BACKGROUND

There have been few cohorts of neonates with coronavirus disease-2019 (COVID-19) reported. As a result, there remains much to be learned about mechanisms of neonatal infection including potential vertical transmission, best methods of testing, and the spectrum of clinical findings. This communication describes the epidemiology, diagnostic test results and clinical findings of neonatal COVID-19 during the pandemic in Iran.

MATERIALS AND METHODS

This is a retrospective cohort study of 19 neonates infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from 10 hospitals throughout Iran. We analyzed obstetrical information, familial COVID-19 status, neonatal medical findings, perinatal complications, hospital readmissions, patterns of repeated testing, and clinical outcomes.

RESULTS

Eleven neonates had family members infected. Five mothers were negative for COVID-19 and four neonates had no identifiable family source of infection. The neonatal mortality rate from COVID-19 was 10%. Seven newborns (37%) were discharged from the hospital as healthy but required readmission for symptoms of COVID-19. There were 2 multifetal gestations - one set each of twins and triplets, each with disparate testing and clinical outcomes. Premature delivery was common, occurring in 12 of 19 infants (63%). Initial testing for COVID-19 was negative in 4 of the 19 neonates (21%) who subsequently became positive. In 2 cases, neonates tested positive at 1 and 2 h after birth which was suspicious for vertical transmission of SARS-CoV-2.

CONCLUSIONS

These cases have notable variation in the epidemiology, clinical features, results of testing and clinical outcomes among the infected newborns. Neonates initially testing negative for COVID-19 may require readmission due to infection. Two neonates were highly suspicious for intrauterine vertical transmission. Repeat testing of neonates who initially test negative for COVID-19 is recommended, without which 21% of neonatal infections would have been undiagnosed.

Breastfed 13 month-old infant of a mother with COVID-19 pneumonia: a case report

BACKGROUND

In China, mothers with confirmed or suspected COVID-19 pneumonia are recommended to stop breastfeeding. However, the evidence to support this guidance is lacking. There have been relatively few cases reported about direct breastfeeding an infant by a mother with SARS-CoV-2 pneumonia. Therefore, it is necessary to assess the safety of breastfeeding and the possible protective effects of breast milk on infants.

CASE PRESENTATION

This report analyzes the case of a mother who continued breastfeeding her 13 month-old child when both were diagnosed with confirmed COVID-19 pneumonia. We describe the clinical presentation, diagnosis, treatment, and outcome. The presence of SARS-CoV-2 nucleic acid was determined in maternal serum, breast milk, nasopharyngeal (NP) swabs and feces, and in infant serum, NP swabs and feces. IgM and IgG antibodies against SARS-CoV-2 were assessed in maternal serum and breast milk and in infant serum. SARS-CoV-2 nucleic acid was not detected in the breast milk, and antibodies against SARS-CoV-2 were detected in the mother's serum and milk.

CONCLUSIONS

The present case further confirms that the possibility of mother-to-child transmission about SARS-CoV-2 via breast milk alone was very small, and breast milk is safe for direct feeding of infants.

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

BACKGROUND

The recent COVID-19 outbreak in Wuhan, China, has quickly spread throughout the world. In this study, we systematically reviewed the clinical features and outcomes of pregnant women with COVID-19.

METHODS

PubMed, Web of Science, EMBASE and MEDLINE were searched from January 1, 2020, to April 16, 2020. Case reports and case series of pregnant women infected with SARS-CoV-2 were included. Two reviewers screened 366 studies and 14 studies were included. Four reviewers independently extracted the features from the studies. We used a random-effects model to analyse the incidence (P) and 95% confidence interval (95% CI). Heterogeneity was assessed using the I2 statistic.

RESULTS

The meta-analysis included 236 pregnant women with COVID-19. The results were as follows: positive CT findings (71%; 95% CI, 0.49-0.93), caesarean section (65%; 95% CI, 0.42-0.87), fever (51%; 95% CI, 0.35-0.67), lymphopenia (49%; 95% CI, 0.29-0.70), coexisting disorders (33%; 95% CI, 0.21-0.44), cough (31%; 95% CI, 0.23-0.39), fetal distress (29%; 95% CI, 0.08-0.49), preterm labor (23%; 95% CI, 0.14-0.32), and severe case or death (12%; 95% CI, 0.03-0.20). The subgroup analysis showed that compared with non-pregnant patients, pregnant women with COVID-19 had significantly lower incidences of fever (pregnant women, 51%; non-pregnant patients, 91%; P < 0.00001) and cough (pregnant women, 31%; non-pregnant patients, 67%; P < 0.0001).

CONCLUSIONS

The incidences of fever, cough and positive CT findings in pregnant women with COVID-19 are less than those in the normal population with COVID-19, but the rate of preterm labor is higher among pregnant with COVID-19 than among normal pregnant women. There is currently no evidence that COVID-19 can spread through vertical transmission.

Breast Feeding in Suspected or Confirmed Cases of COVID 19-a New Perspective

The encounter with the rampant novel Corona virus infection has led the healthcare system across the world to update and modify its tools to fight this pandemic. Pregnancy, childbirth and breast feeding are a set of special situations to be dealt in women afflicted with Covid-19. Currently there is no universal consensus on managing the issue of breast feeding with rooming-in of the neonates in women with suspected or confirmed Covid-19. Literature is still evolving with contradictory guidelines from various authorities across the globe. This review intends to analyse the available evidence on managing breast feeding in such women and to derive a practically plausible approach in handling such situations.

[Clinical features of coronavirus disease 2019 in children: a systemic review of severe acute respiratory syndrome, Middle East respiratory syndrome, and coronavirus disease 2019]

OBJECTIVE

To systematically summarize the clinical features of coronavirus disease 2019 (COVID-19) in children.

METHODS

PubMed, Embase, Web of Science, The Cochrane Library, CNKI, Weipu Database, and Wanfang Database were searched for clinical studies on COVID-19 in children published up to May 21, 2020. Two reviewers independently screened the articles, extracted data, and assessed the risk of bias of the studies included. A descriptive analysis was then performed for the studies. Related indices between children with COVID-19 and severe acute respiratory syndromes (SARS) or Middle East respiratory syndrome (MERS) were compared.

RESULTS

A total of 75 studies were included, with a total of 806 children with COVID-19. The research results showed that the age of the children ranged from 36 hours after birth to 18 years, with a male-female ratio of 1.21 : 1. Similar to SARS and MERS, COVID-19 often occurred with familial aggregation, and such cases accounted for 74.6% (601/806). The children with COVID-19, SARS, and MERS had similar clinical symptoms, mainly fever and cough. Some children had gastrointestinal symptoms. The children with asymptomatic infection accounted for 17.9% (144/806) of COVID-19 cases, 2.5% (2/81) of SARS cases, and 57.1% (12/21) of MERS cases. The children with COVID-19 and MERS mainly had bilateral lesions on chest imaging examination, with a positive rate of lesions of 63.4% (421/664) and 26.3% (5/19) respectively, which were lower than the corresponding positive rates of viral nucleic acid detection, which were 99.8% and 100% respectively. The chest radiological examination of the children with SARS mainly showed unilateral lesion, with a positive rate of imaging of 88.9% (72/81), which was higher than the corresponding positive rate of viral nucleic acid detection (29.2%). Viral nucleic acid was detected in the feces of children with COVID-19 or SARS, with positive rates of 60.2% (56/93) and 71.4% (5/7) respectively. The children with COVID-19 had a rate of severe disease of 4.6% (31/686) and a mortality rate of 0.1% (1/806), the children with SARS had a rate of severe disease of 1.5% (1/68) and a mortality rate of 0%, and those with MERS had a rate of severe disease of 14.3% (3/21) and a mortality rate of 9.5% (2/21).

CONCLUSIONS

Children with COVID-19 have similar symptoms to those with SARS or MERS, mainly fever and cough. Asymptomatic infection is observed in all three diseases. Children with COVID-19 or SARS have milder disease conditions than those with MERS. COVID-19 in children often occurs with familial aggregation. Epidemiological contact history, imaging examination findings, and viral nucleic acid testing results are important bases for the diagnosis of COVID-19.

Coronavirus disease 2019 (COVID-19) in children: a systematic review of imaging findings

BACKGROUND

COVID-19 is a novel coronavirus infection that can cause a severe respiratory illness and has been declared a pandemic by the World Health Organization (WHO). Because children appear to be less severely affected than adults, their imaging appearances have not been extensively reported.

OBJECTIVE

To systematically review available literature regarding imaging findings in paediatric cases of COVID-19.

MATERIALS AND METHODS

We searched four databases (Medline, Embase, Cochrane, Google Scholar) for articles describing imaging findings in children with COVID-19. We included all modalities, age <18 years, and foreign language articles, using descriptive statistics to identify patterns and locations of imaging findings, and their association with outcomes.

RESULTS

Twenty-two articles were included, reporting chest imaging findings in 431 children, of whom 421 (97.7%) underwent CT. Criteria for imaging were lacking. At diagnosis, 143/421 (34.0%) had a normal CT. Abnormalities were more common in the lower lobes and were predominantly unilateral. The most common imaging pattern was ground-glass opacification (159/255, 62.4%). None of the studies described lymphadenopathy, while pleural effusions were rare (three cases). Improvement at follow-up CT imaging (3-15 days later) was seen in 29/100 (29%), remained normal in 25/100 (25%) and progressed in 9/100 (9%).

CONCLUSION

CT chest findings in children with COVID-19 are frequently normal or mild. Lower lobes are predominantly affected by patchy ground-glass opacification. Appearances at follow-up remain normal or improve in the majority of children. Chest CT imaging adds little to the further management of the patient and should be reserved for severe cases or for identifying alternative diagnoses.

CT features of novel coronavirus pneumonia (COVID-19) in children

A serious epidemic of COVID-19 broke out in Wuhan, Hubei Province, China, and spread to other Chinese cities and several countries now. As the majority of patients infected with COVID-19 had chest CT abnormality, chest CT has become an important tool for early diagnosis of COVID-19 and monitoring disease progression. There is growing evidence that children are also susceptible to COVID-19 and have atypical presentations compared with adults. This review is mainly about the differences in clinical symptom spectrum, diagnosis of COVID-19, and CT imaging findings between adults and children, while highlighting the value of radiology in prevention and control of COVID-19 in pediatric patients. KEY POINTS: • Compared with adults, pediatric patients with COVID-19 have the characteristics of lower incidence, slighter clinical symptoms, shorter course of disease, and fewer severe cases. • The chest CT characteristics of COVID-19 in pediatric patients were atypical, with more localized GGO extent, lower GGO attenuation, and relatively rare interlobular septal thickening. • Chest CT should be used with more caution in pediatric patients with COVID-19 to protect this vulnerable population from risking radiation.

Maternal and neonatal response to COVID-19

The risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to maternal and newborn health has yet to be determined. Several reports suggest pregnancy does not typically increase the severity of maternal disease; however, cases of preeclampsia and preterm birth have been infrequently reported. Reports of placental infection and vertical transmission are rare. Interestingly, despite lack of SARS-CoV-2 placenta infection, there are several reports of significant abnormalities in placenta morphology. Continued research on pregnant women infected with SARS-CoV-2 and their offspring is vitally important.

Perinatal transmission with SARS-CoV-2 and route of pregnancy termination: a narrative review

OBJECTIVE

Analyze newborns diagnosed with SARS-CoV-2 performed with RT-PCR at birth or during the first days of birth and to look for an association with the route of birth.

METHODS

We conducted a comprehensive literature search for newborns diagnosed with COVID-19 using PubMed, LILACS and Google scholar until May 15, 2020, looking for published articles with pregnancy, vertical transmission, intrauterine transmission, neonates, delivery.

RESULTS

There were found 10 articles with a total of 15 newborn infected with SARS-CoV-2 according to positive PCR at birth or in the first days of birth. Eleven newborn birth by cesarean section and 4 vaginally. Of the 11 cases with cesarean section, two presented premature rupture of the membranes. Seven newborns developed pneumonia, of which two had ruptured membranes and one was born by vaginal delivery.

CONCLUSION

This review shows that there is perinatal or neonatal infection with SARS-CoV-2 by finding a positive PCR in the first days of birth. In addition, that there is more possibility of neonatal infection if the birth is vaginal or if there is premature rupture of the membranes before cesarean section. Vaginal delivery and premature rupture of membranes should be considered as risk factors for perinatal infection.

A Message from the Human Placenta: Structural and Immunomodulatory Defense against SARS-CoV-2

The outbreak of the coronavirus disease 2019 (COVID-19) pandemic has caused a global public health crisis. Viral infections may predispose pregnant women to a higher rate of pregnancy complications, including preterm births, miscarriage, and stillbirth. Despite reports of neonatal COVID-19, definitive proof of vertical transmission is still lacking. In this review, we summarize studies regarding the potential evidence for transplacental transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), characterize the expression of its receptors and proteases, describe the placental pathology and analyze virus-host interactions at the maternal-fetal interface. We focus on the syncytium, the barrier between mother and fetus, and describe in detail its physical and structural defense against viral infections. We further discuss the potential molecular mechanisms, whereby the placenta serves as a defense front against pathogens by regulating the interferon type III signaling, microRNA-triggered autophagy and the nuclear factor-κB pathway. Based on these data, we conclude that vertical transmission may occur but rare, ascribed to the potent physical barrier, the fine-regulated placental immune defense and modulation strategies. Particularly, immunomodulatory mechanisms employed by the placenta may mitigate violent immune response, maybe soften cytokine storm tightly associated with severely ill COVID-19 patients, possibly minimizing cell and tissue damages, and potentially reducing SARS-CoV-2 transmission.

Perinatal management of SARS-CoV-2 infection in a level III University Hospital

Over the past 4 months, SARS-CoV-2 pandemic has spread all over the world. The lack of understanding of this pandemic epidemiological characteristics, clinical implications and long term consequences have raised concern among healthcare workers. Pregnant women and newborns are a particularly worrisome population since data referring to real infection impact in these patients are scarce and management controversial. We report on the perinatal management of the first consecutive ten mother-infant dyads of SARS-CoV-2 infection complicated pregnancy. All mothers were included in newborn management planning prior to delivery and decided on separation from their newborns; nine decided on postponing breastfeeding until SARS-CoV-2 negativity while maintaining lactation stimulation. No evidence of vertical transmission was found (all NP swab and bronchial secretions SARS-CoV-2 RT-PCR were negative). No newborn developed clinical evidence of infection. In the face of current scientific uncertainty, decisions of perinatal management, such as mother-infant separation and breastfeeding, must involve parents in a process of shared decision making.

Vertical transmission of SARS CoV-2: a systematic review

OBJECTIVE

The aim of this study is to review the current evidence on the vertical transmission of SARS CoV-2.

METHODS

Combination of the following keywords; COVID-19, SARS CoV-2, placenta, vertical transmission, intrauterine infection, breast milk were searched in databases.

RESULTS

In the 50 studies included, 17 newborns testing positive for SARS CoV-2 by RT-PCR were reported. In three neonates, SARS-CoV-2 IgG and IgM levels were elevated. Eight placental tissues testing positive for the virus were reported. Three positive RT-PCR results of test of breast milk have been reported recently. One amniotic fluid testing positive was reported.

CONCLUSION

Possible vertical transmission of SARS CoV-2 has been observed in some studies currently. More RT-PCR tests on amniotic fluid, placenta, breast milk and cord blood are required.

Early Intravenous Immunoglobulin as an Effective Drug for the Treatment of COVID-19: A Case Series and Case Review

Introduction: The outbreak of coronavirus disease 2019 (COVID-19) should be considered a serious threat to global public health. Due to a large number of infected and dead people, the development of approaches to control the epidemic condition, as well as effective and available drugs, is very important. Case Presentation: In this study, we presented three cases with COVID-19 admitted to the Imam Reza Hospital. A high dose of intravenous immunoglobulin (IVIG) was used for patients as potent and safe treatment. Moreover, case reports and case series focusing on the patients with COVID-19 were reviewed in the present study. During the literature search, 27 patients with COVID-19 were identified in 14 studies. Fever, sore throat, dry cough, fatigue, chills, and muscle pain were the common primary complications of the patients. Kaletra, oseltamivir, ceftriaxone, hydroxychloroquine, azithromycin, and IVIG were the most prevalent drugs for the treatment of COVID-19. Conclusions: Except for the current study, IVIG was utilized in two other studies to treat patients with COVID-19, who did not respond to other therapies.

Adverse outcomes in SAR-CoV-2 (COVID-19) and SARS virus related pregnancies with probable vertical transmission

The global severe acute respiratory syndrome-related coronavirus SARS-CoV-2 (COVID-19) pandemic has had an unprecedented impact on all aspects of daily life and healthcare. Information on the infection risks for pregnant women and their offspring have so far been limited to small case series, until a large UK report on 427 SARS-CoV-2 infected pregnant women was published. Previous SARS epidemic experiences were drawn upon. Diagnostic use of real time polymerase chain reaction (RT-PCR) and IgG and IgM antibody tests are fraught with concerns of non-validation and false negative results, as are sampling methodologies. Virtually no information on controls accompany these reports. Infection of the mother and baby has serious implications for obstetric and neonatal care. Information on early and late stage pregnancy infection and the relationship to severity of infection on fetal development is both useful and clearly warranted. An increasing number of reports centre around mildly infected women showing no evidence of fetal infection while a few reports suggesting vertical transmission require further validation. Vertical transmission from mother to baby however small would have profound health implications for obstetric and neonatal care and fetal abnormalities. Some data suggesting intrapartum vertical transmission from mother to baby cannot be dismissed given the lack of controls and limitations of diagnostic viral tests. This analysis covers some key early reports addressing pregnancy outcomes following SARS-CoV-2 infection.

Severe coronavirus infection in pregnancy: challenging cases report

There are few data on the impact of COVID-19 in pregnancy, however, analyzing these data is important to guide the clinical practice, covering the early prevention, detection, patients’ isolation, epidemiological investigation, diagnosis and early treatment. This is a report of three cases of COVID-19 confirmed by real-time reverse transcription – polymerase chain reaction (RT-PCR) of nasopharyngeal secretions collected in swabs from pregnant women in the city of Vitoria, Espirito Santo State, Brazil. In the three cases, all the patients presented with fever, one had shortness of breath, one had diarrhea, two of them reported abdominal pain and two of them had cough. The three patients progressed with a severe clinical evolution of COVID-19. The permanence in the intensive care unit (ICU) was more than 10 days. Two of them recovered and one remained in the ICU with irreversible refractory shock, multiple organ failure and died. The mode of delivery was individualized and based on the obstetric indication and severity of the maternal infection, and the cesarean section was indicated in the two severe maternal COVID-19 cases that evolved favorably. These newborns were premature and tested negative for COVID-19 by RT-PCR.

COVID-19: review of case reports

Recently published case reports relating to anesthesia in patients with coronavirus disease (COVID-19) were reviewed. The diagnosis of COVID-19 was confirmed by positive results of reverse transcriptase polymerase chain reaction test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Numerous reports handled emergency cesarean delivery. Primary symptoms and laboratory data of pregnant women with COVID-19 were similar to those of non-pregnant patients. Although the mortality rate is reported to be high after surgery in patients with COVID-19, cesarean delivery was successfully performed under regional anesthesia in most cases and postoperative course was favorable both in the parents and newborns. There is no direct evidence of vertical mother-to-child transmission of SARS-CoV-2; however, a diagnosis of COVID-19 was made in a newborn two hours after delivery from a pregnant woman with COVID-19, based on the increased immunoglobulin levels and deranged liver function, suggesting that its possibility cannot be completely eliminated. Emergency cerebral shunt reconstruction was performed repeatedly in an eight-month-old boy with COVID-19. The tracheal tube was removed in the operating room after surgery and postoperative course was uneventful. All the procedures should be performed in isolated operating rooms with medical staff with level-3 personal protection to ensure the safety of patients and health care providers.

COVID-19 Presented with Gastrointestinal Manifestations in an 11-Days-Old Neonate: A Case Report and Review of the Literature

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the leading cause of death since December 2019. The most common clinical manifestations are cough, fever, and dyspnea; however, non-specific findings are also reported. This virus affects all age groups with a predilection to the adults, but children and neonates can also be affected. Case Presentation: An 11-days-old male neonate was brought to the hospital with chief complaints of vomiting and severe watery diarrhea. All laboratory data, including the stool OB/OP test, were normal except for leukocytosis. His parents were asymptomatic. In the following, qRT-PCR from neonate’s nasopharynx reported positive. Supportive and symptomatic treatments were done. The neonate discharged from the hospital without any significant sequelae. Conclusions: Extrapulmonary manifestation of COVID-19, especially gastrointestinal findings, should be considered in neonates to avoid possible complications and further spread of the disease.

Pregnancy and COVID-19: a systematic review of maternal, obstetric and neonatal outcomes

BACKGROUND

There is limited information related to COVID-19 in pregnancy.

OBJECTIVES

Evaluate the impact of COVID-19 during pregnancy.Search strategy: Searches were systematically carried out in PubMed, Scopus database and WHO database.Selection criteria: Studies with information related to the effects of COVID-19 in pregnancy, concerning maternal, obstetric, and neonatal outcomes were included.Data collection and analysis: Data were extracted for systematic review following PRISMA guidelines. CARE and STROBE were used to evaluate the quality of data.Main Results: A total of 8 studies involving 95 pregnant women and 51 neonates were included. Overall, the quality was considered good in four studies, moderate in three and poor in one. Among pregnant women, 26% had a history of epidemiological exposure to SARS-CoV-2. The most common symptoms presented were fever (55%), cough (38%) and fatigue (11%). In 50 deliveries, 94% were cesarean sections and 35% were preterm births. Of the 51 neonates, 20% had low birth weight and 1 tested positive for Sars-CoV-2. There was 1 neonatal death, not related to the viral infection, and no cases of severe neonatal asphyxia.

CONCLUSIONS

The information compiled in this systematic review may help healthcare providers administer the best possible care.

Pregnancy, Viral Infection, and COVID-19

Pregnancy comprises a unique immunological condition, to allow fetal development and to protect the host from pathogenic infections. Viral infections during pregnancy can disrupt immunological tolerance and may generate deleterious effects on the fetus. Despite these possible links between pregnancy and infection-induced morbidity, it is unclear how pregnancy interferes with maternal response to some viral pathogens. In this context, the novel coronavirus (SARS-CoV-2) can induce the coronavirus diseases-2019 (COVID-19) in pregnant women. The potential risk of vertical transmission is unclear, babies born from COVID-19-positive mothers seems to have no serious clinical symptoms, the possible mechanisms are discussed, which highlights that checking the children's outcome and more research is warranted. In this review, we investigate the reports concerning viral infections and COVID-19 during pregnancy, to establish a correlation and possible implications of COVID-19 during pregnancy and neonatal's health.

Maternal death due to COVID-19

BACKGROUND

Despite 2.5 million infections and 169,000 deaths worldwide (as of April 20, 2020), no maternal deaths and only a few pregnant women afflicted with severe respiratory morbidity have been reported to be related to COVID-19 disease. Given the disproportionate burden of severe and fatal respiratory disease previously documented among pregnant women following other coronavirus-related outbreaks (SARS-CoV in 2003 and MERS-CoV in 2012) and influenza pandemics over the last century, the absence of reported maternal morbidity and mortality with COVID-19 disease is unexpected.

OBJECTIVE

To describe maternal and perinatal outcomes and death in a case series of pregnant women with COVID-19 disease.

STUDY DESIGN

We describe here a multiinstitution adjudicated case series from Iran that includes 9 pregnant women diagnosed with severe COVID-19 disease in their second or third trimester. All 9 pregnant women received a diagnosis of SARS-CoV-2 infection by reverse transcription polymerase chain reaction nucleic acid testing. Outcomes of these women were compared with their familial/household members with contact to the affected patient on or after their symptom onset. All data were reported at death or after a minimum of 14 days from date of admission with COVID-19 disease.

RESULTS

Among 9 pregnant women with severe COVID-19 disease, at the time of reporting, 7 of 9 died, 1 of 9 remains critically ill and ventilator dependent, and 1 of 9 recovered after prolonged hospitalization. We obtained self-verified familial/household cohort data in all 9 cases, and in each and every instance, maternal outcomes were more severe compared with outcomes of other high- and low-risk familial/household members (n=33 members for comparison).

CONCLUSION

We report herein maternal deaths owing to COVID-19 disease. Until rigorously collected surveillance data emerge, it is prudent to be aware of the potential for maternal death among pregnant women diagnosed as having COVID-19 disease in their second or third trimester.

SARS-COV-2 infection in children and newborns: a systematic review

A recent outbreak of a novel Coronavirus responsible for a Severe Acute Respiratory Syndrome (SARS-CoV-2) is spreading globally. The aim of this study was to systematically review main clinical characteristics and outcomes of SARS-CoV-2 infections in pediatric age. An electronic search was conducted in PubMed database. Papers published between 1 January and 1 May 2020 including children aged 0-18 years were selected. Sixty-two studies and three reviews were included, with a total sample size of 7480 children (2428/4660 males, 52.1%; weighted mean age 7.6 years). Patients showed mainly mild (608/1432, 42.5%) and moderate (567/1432, 39.6%) signs of the infection. About 2% of children were admitted to the pediatric intensive care unit. The most commonly described symptoms were fever (51.6%) and cough (47.3%). Laboratory findings were often unremarkable. Children underwent a chest CT scan in 73.9% of all cases, and 32.7% resulted normal. Overall, the estimated mortality was 0.08%. A higher proportion of newborns was severely ill (12%) and dyspnea was the most common reported sign (40%).Conclusion: SARS-CoV-2 affects children less severely than adults. Laboratory and radiology findings are mainly nonspecific. Larger epidemiological and clinical cohort studies are needed to better understand possible implications of COVID-19 infection in children.What is Known:• A novel Coronavirus has been recently identified as responsible for a new Severe Acute Respiratory Syndrome (SARS-CoV-2) spreading globally.• There is limited evidence on SARS-CoV2 infection in children.What is New:• Systematically reviewed available evidence showed that children with SARS-CoV-2 infection may have a less severe pattern of disease in comparison to adults.• Blood tests and radiology findings are mainly nonspecific in children but may help to identify those who are severely ill.

How to prevent in-hospital COVID-19 infection and reassure women about the safety of pregnancy: Experience from an obstetric center in China

OBJECTIVE

This study aimed to describe the emergency responses to coronavirus disease 2019 (COVID-19) for pregnant patients at our hospital and their effect on hospital operations and patients' outcomes.

METHODS

We developed strategies to prevent hospital-associated transmission of COVID-19 in obstetric care. Infrastructure, including the fever clinic and wards, were modified. Outpatient volume was controlled and screening processes were strictly performed. Verification of the virus was compulsory for non-surgery and non-emergency patients. Emergency operations were performed in a negative pressure theater with surgeons fully protected. Outcomes were analyzed and the patients' characteristics were evaluated. The effect of intervention on depressed and anxious patients was assessed. Data from the first 2 months of 2019 and 2020 were compared.

RESULTS

No in-hospital COVID-19 infections occurred in our unit. During the epidemic, patient volume significantly decreased. While major characteristics of patients were similar, a higher prevalence of gestational hypertension was found in 2020 than in 2019. Psychological interventions showed optimistic effects in ameliorating depression and anxiety at the beginning of the COVID-19 pandemic.

CONCLUSIONS

Our strategies were effective in preventing in-hospital infection of COVID-19 and reassuring women about the safety of pregnancy. Monitoring and managing psychological issues were necessary during this critical period.

Breastfeeding during the COVID-19 pandemic: Suggestions on behalf of woman study group of AMD

SARS-Cov2 infection has recently spread to Italy with important consequences on pregnancy management, mother and child health and mother-child contact. Breastfeeding improves the health of mother and child and reduces risk of neonatal infection with other pathogens that are likely to cause serious illness. To date no evidence confirmed COVID-19 vertical transmission from infected pregnant mother to their fetus. However it is well known that an infected mother can transmit the COVID-19 virus through respiratory droplets during breastfeeding or intimate contact. Thus, the mothers with known or suspected COVID-19 should adhere to standard and contact precautions during breastfeeding. Woman Study Group of AMD, after reviewing current knowledge about COVID-19 vertical transmission and the compatibility of breastfeeding in COVID-19 mother, the available recommendations from Health Care Organizations and main experts opinions, issued the following suggestions on breastfeeding during the COVID-19 pandemic, addressed both to mothers with and without diabetes. It should be considered that following suggestions may change in the future when more evidence is acquired regarding SARS-Cov2 infection.

Breastfeeding and coronavirus disease-2019: Ad interim indications of the Italian Society of Neonatology endorsed by the Union of European Neonatal & Perinatal Societies

The recent COVID-19 pandemic has spread to Italy with heavy consequences on public health and economics. Besides the possible consequences of COVID-19 infection on a pregnant woman and the fetus, a major concern is related to the potential effect on neonatal outcome, the appropriate management of the mother-newborn dyad, and finally the compatibility of maternal COVID-19 infection with breastfeeding. The Italian Society on Neonatology (SIN) after reviewing the limited scientific knowledge on the compatibility of breastfeeding in the COVID-19 mother and the available statements from Health Care Organizations has issued the following indications that have been endorsed by the Union of European Neonatal & Perinatal Societies (UENPS). If a mother previously identified as COVID-19 positive or under investigation for COVID-19 is asymptomatic or paucisymptomatic at delivery, rooming-in is feasible, and direct breastfeeding is advisable, under strict measures of infection control. On the contrary, when a mother with COVID-19 is too sick to care for the newborn, the neonate will be managed separately and fed fresh expressed breast milk, with no need to pasteurize it, as human milk is not believed to be a vehicle of COVID-19. We recognize that this guidance might be subject to change in the future when further knowledge will be acquired about the COVID-19 pandemic, the perinatal transmission of SARS-CoV-2, and clinical characteristics of cases of neonatal COVID-19.
