The association between maternal characteristics and SARS-CoV-2 in pregnancy: a population-based registry study in Sweden and Norway.

The objectives of the current study were to identify risk factors for SARS-CoV-2 positivity, and to address how different testing strategies, choice of comparison group, and population background characteristics may influence observed associations. National registries data for 107,627 pregnant women in Sweden and 81,195 in Norway, were used to identify risk factors for SARS-CoV-2, separately for women under non-universal testing (testing by indication) and universal testing (testing of all pregnant women in contact with a delivery ward). We also investigated underlying characteristics associated with testing for SARS-CoV-2. Overall, 2.1% of pregnant women in Sweden and 1.1% in Norway were test-positive during the pandemic's first 18 months. We show that the choice of test strategy for SARS-CoV-2 provided different associations with risk factors for the disease; for instance, women who were overweight, obese or had gestational diabetes had increased odds of being test-positive under non-universal testing, but not under universal testing. Nevertheless, a consistent pattern of association between being born in the Middle East and Africa and test-positivity was found independent of test strategy and in both countries. These women were also less likely to get tested. Our results are useful to consider for surveillance and clinical recommendations for pregnant women during the current and future pandemics.

Pregnancy and risk of COVID-19: a Norwegian registry-linkage study.

OBJECTIVE: To compare the risk of acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and contact with specialist healthcare services for coronavirus disease 2019 (COVID-19) between pregnant and non-pregnant women. POPULATION OR SAMPLE: All women ages 15-45 living in Norway on 1 March 2020 (n = 1 033 699). METHODS: We linked information from the national birth, patient, communicable diseases and education databases using unique national identifiers. MAIN OUTCOME MEASURE: We estimated hazard ratios (HR) among pregnant compared to non-pregnant women of having a positive test for SARS-CoV-2, a diagnosis of COVID-19 in specialist healthcare, or hospitalisation with COVID-19 using Cox regression. Multivariable analyses adjusted for age, marital status, education, income, country of birth and underlying medical conditions. RESULTS: Pregnant women were not more likely to be tested for or to a have a positive SARS-CoV-2 test (adjusted HR 0.99; 95% CI 0.92-1.07). Pregnant women had higher risk of hospitalisation with COVID-19 (HR 4.70, 95% CI 3.51-6.30) and any type of specialist care for COVID-19 (HR 3.46, 95% CI 2.89-4.14). Pregnant women born outside Scandinavia were less likely to be tested, and at higher risk of a positive test (HR 2.37, 95% CI 2.51-8.87). Compared with pregnant Scandinavian-born women, pregnant women with minority background had a higher risk of hospitalisation with COVID-19 (HR 4.72, 95% CI 2.51-8.87). CONCLUSION: Pregnant women were not more likely to be infected with SARS-CoV-2. Still, pregnant women with COVID-19, especially those born outside of Scandinavia, were more likely to be hospitalised. TWEETABLE ABSTRACT: Pregnant women are at increased risk of hospitalisation for COVID-19.

SARS-CoV-2 infection in pregnancy during the first wave of COVID-19 in the Netherlands: a prospective nationwide population-based cohort study (NethOSS).

OBJECTIVE: To describe characteristics, risk factors and maternal, obstetric and neonatal outcomes of pregnant women infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). DESIGN: Multi-centre prospective population-based cohort study. SETTING: Nationwide study in the Netherlands. POPULATION: Pregnant women with confirmed SARS-CoV-2 infection admitted to hospital or in home-isolation: 1 March 2020 to 31 August 2020. METHODS: Pregnant women with positive polymerase chain reaction or antibody tests were registered using the Netherlands Obstetrics Surveillance System (NethOSS). (Selective) testing occurred according to national guidelines. Data from the national birth registry (pregnant pre-coronavirus disease 2019 [COVID-19] cohort) and an age-matched cohort of COVID-19-positive women (National Institute for Public Health and the Environment; fertile age COVID-19 cohort) were used as reference. MAIN OUTCOME MEASURES: Incidence of SARS-CoV-2 infection in pregnant women. Maternal, obstetric and neonatal outcomes including hospital and intensive care admission. RESULTS: Of 376 registered pregnant women with confirmed SARS-CoV-2 infection, 20% (74/376) were admitted to hospital, of whom 84% (62/74) were due to SARS-CoV-2; 10% (6/62) were admitted to intensive care and 15% (9/62) to obstetric high-care units. Risk factors for admission were non-European country of origin (odds ratio [OR] 1.73, 95% CI 1.01-2.96) and being overweight/obese (OR 1.86, 95% CI 1.51-3.20). No maternal or perinatal deaths occurred. Caesarean section after labour-onset was increased (OR 1.58, 95% CI 1.09-2.28). Hospital and intensive care admission were higher compared with the fertile age COVID-19 cohort (OR 6.75, 95% CI 5.18-8.81 and OR 2.52, 95% CI 1.11-5.77, respectively). CONCLUSIONS: Non-European country of origin and being overweight/obese are risk factors for severe course of SARS-CoV-2 infection in pregnancy, risk of caesarean section and hospital and intensive care unit admission are increased. TWEETABLE ABSTRACT: Pregnant women with SARS-CoV-2 in the Netherlands show increased hospital/ICU admission and caesarean section.

A review of 92 obstetric patients with COVID-19 in the Bronx, New York and their peripartum anaesthetic management.

INTRODUCTION: The Bronx is a borough of New York City that has been profoundly affected by the COVID-19 pandemic. Limited reports exist discussing the anaesthetic management of obstetric patients infected with COVID-19. We review a cohort of obstetric patients in the Bronx with COVID-19 and report their delivery data, anaesthetic management, and maternal-fetal outcomes. MATERIAL AND METHODS: We reviewed 92 pregnant patients with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) who delivered between 1 February 2020 and 1 May 2020. Medical records were reviewed for patient characteristics, anaesthetic management, and clinical outcomes. Patients were stratified by mode of delivery and COVID-19 disease severity. RESULTS: Of the 92 deliveries, 49 (53%) were vaginal, 14 (15%) were scheduled caesareans, and 29 (32%) were unscheduled caesareans. 64 patients (70%) were asymptomatic for COVID-19 (mild disease: 18 patients [19%], moderate disease: 7 patients [8%], severe disease: 2 patients [2%], critical disease: 1 patient [1%]). 83 patients (90%) received neuraxial analgesia and/or anaesthesia, with combined spinal-epidural (CSE) and dural puncture epidural (DPE) as the most common techniques. 5 patients (5%) required general anaesthesia (GA) for caesarean delivery, 3 (3%) of whom were intubated for severe or critical COVID-19 disease. CONCLUSIONS: Given the risks associated with SARS-CoV-2 aerosol transmission, GA was avoided in all but the most critically ill patients. CSE and DPE were optimal for minimizing catheter failure rates and risk of conversion to GA. SARS-CoV-2 infection in obstetric patients may be associated with an increased risk for adverse outcomes including preeclampsia, preterm delivery, unscheduled caesarean delivery, and mechanical ventilation.

COVID-19 and the neonatal microbiome: will the pandemic cost infants their microbes?

Mortality and morbidity from SARS-CoV2 (COVID-19) infections in children remains low, including an exceedingly low rate of horizontal and vertical transmission. However, unforeseen complications to childhood health have emerged secondary to the pandemic. Few studies to date have examined unintended complications of the pandemic in newborns and infants. In this Commentary, we discuss the impact that COVID-19 may have on inheritance of the newborn microbiome and its assembly throughout the first years of life. In the early stages of the pandemic when vertical transmission of COVID-19 was poorly understood, several studies reported increased rates of C-sections in COVID-19 positive women. Initial recommendations discouraged COVID-19 positive mothers from breastfeeding and participating in skin-to-skin care, advising them to isolate during their window of infectivity. These shifts in perinatal care can adversely impact microbial colonization during the first 1000 days of life. While obstetrical and neonatal management have evolved to reflect our current knowledge of perinatal transmission, we are observing other changes in early life exposures of infants, including increased attention to hygiene, fewer social interactions, and decreased global travel, all of which are major drivers of early-life gut colonization. Composition of the gut microbiota in adults directly impacts severity of infection, suggesting a role of microbial communities in modulating immune responses to COVID-19. Conversely, the role of the intestinal microbiome in susceptibility and severity of COVID-19 in newborns and children remains unknown. The onset of adulthood diseases is related to the establishment of a healthy gut microbiome during childhood. As we continue to define COVID-19 biology, further research is necessary to understand how acquisition of the neonatal microbiome is affected by the pandemic. Furthermore, infection control measures must be balanced with strategies that promote microbial diversity to impart optimal health outcomes and potentially modulate susceptibility of children to COVID-19.

Characteristics and Pregnancy Outcomes of Asymptomatic and Symptomatic Women with COVID-19: Lessons from Hospitals in Wuhan.

INTRODUCTION: The objective of the study was to compare the clinical characteristics and pregnancy outcomes of asymptomatic and symptomatic pregnant women with confirmed COVID-19 in the third trimester. METHODOLOGY: Forty-one patients were enrolled in this study from two COVID-19 designated hospitals in Wuhan. Patients underwent chest CT scans for screening and were divided into two groups based on pneumonia-related syndromes. The clinical characteristics and pregnancy outcomes were reviewed and compared. RESULTS: Among the sample of pregnant women infected with SARS-CoV-2 in the third trimester, there was no mortality or severe complications in the mothers nor newborns. Nearly 40% of the patients in the study were asymptomatic. The most common pneumonia-related symptom in symptomatic pregnant patients was cough. Asymptomatic patients had a significantly shorter duration of hospitalisation and a lower rate of positive RT-PCR testing compared with symptomatic patients. There was no statistically significant difference in antibody test results between asymptomatic and symptomatic patients during hospitalisation, while the positive rate of IgM antibody testing was significantly lower in asymptomatic patients during follow-up. CONCLUSIONS: Clinical manifestation of pregnant women infected with SARS-CoV-2 were atypical and concealed. Screening of possible COVID-19 patients should be strengthened, through serial or combined testing of laboratory testing or radiological testing, before pregnant women are admitted to hospital.

Molecular Insights into the Thrombotic and Microvascular Injury in Placental Endothelium of Women with Mild or Severe COVID-19.

Clinical manifestations of coronavirus disease 2019 (COVID-19) in pregnant women are diverse, and little is known of the impact of the disease on placental physiology. Severe acute respiratory syndrome coronavirus (SARS-CoV-2) has been detected in the human placenta, and its binding receptor ACE2 is present in a variety of placental cells, including endothelium. Here, we analyze the impact of COVID-19 in placental endothelium, studying by immunofluorescence the expression of von Willebrand factor (vWf), claudin-5, and vascular endothelial (VE) cadherin in the decidua and chorionic villi of placentas from women with mild and severe COVID-19 in comparison to healthy controls. Our results indicate that: (1) vWf expression increases in the endothelium of decidua and chorionic villi of placentas derived from women with COVID-19, being higher in severe cases; (2) Claudin-5 and VE-cadherin expression decrease in the decidua and chorionic villus of placentas from women with severe COVID-19 but not in those with mild disease. Placental histological analysis reveals thrombosis, infarcts, and vascular wall remodeling, confirming the deleterious effect of COVID-19 on placental vessels. Together, these results suggest that placentas from women with COVID-19 have a condition of leaky endothelium and thrombosis, which is sensitive to disease severity.

COVID-19 impact on perinatal care: risk factors, clinical manifestation and prophylaxis. Polish experts' opinion for December 2020.

Rapid spread of severe acute respiratory syndrome coranovirus-2 virus (SARS-CoV-2) caused the pandemic of Coronavirus Disease 19 (COVID-19). Clinical course of the disease presents symptoms mainly from the respiratory system such as: cough, dyspnea and fever, and among some patients, can deteriorate even further to acute respiratory distress syndrome (ARDS), eventually leading to death. This outbreak, as well as previous ones (SARS, MERS) pose a significant challenge for health care managers, epidemiologists and physicians. Below we are presenting the clinical profile of the COVID-19 among special group of patients; pregnant women and newborns, who require special clinical management during hospitalization. In the summary of this manuscript, we present practical guidelines for managing pregnant women infected with SARS-CoV-2, labor and care of the newborn of a positive mother, as well as practical guidelines for COVID-19 vaccinations. It is important to stress, that this manuscript is based on information available as of December 2020.

COVID-19: Our Current Knowledge of Epidemiology, Pathology, Therapeutic Approaches, and Diagnostic Methods.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) firstly emerged in Wuhan, China at the end of 2019. After going through the experimental process, the virus was named the novel coronavirus (2019-nCoV) by the World Health Organization (WHO) in February 2020 which has created a global pandemic. The coronavirus disease 2019 (COVID-19) infection is challenging the people who are especially suffering from chronic health problems such as asthma, diabetes, and heart disease or immune system deteriorating disorders, including cancers, Alzheimer's, etc. Other predisposing/risk factors consist of smoking and age (elderly people are at higher risk). The 2019-nCoV attacks epithelial cells in all organs, particularly epithelial cells in the lungs, resulting in viral pneumonia. The 2019-nCoV starts its invasion with the attachment and entry into the respiratory tract epithelial cells via Angiotensin-Converting Enzyme 2 (ACE2) receptors on the epithelial cells. The critical problem with 2019-nCoV is its ability in human to human asymptomatic transmission which causes the rapid and hidden spread of the virus among the population. Also, there are several reports of highly variable and tightly case-dependent clinical manifestations caused by SARS-CoV2, which made the virus more enigmatic. The clinical symptoms are varied from common manifestations which occurred in flu and cold, such as cough, fever, body-ache, trembling, and runny nose to severe conditions, like the Acute Respiratory Distress Syndrome (ARDS) or even uncommon/unusual symptoms such as anosmia, skin color change, and stroke. In fact, besides serious injuries in the respiratory system, COVID-19 invades and damages various organs, including the kidney, liver, gastrointestinal, and nervous system. Accordingly, to cut the transmission chain of disease and control the infection spread. One of the major solutions seems to be early detection of the carriers, particularly the asymptomatic people, with sensitive and accurate diagnostic techniques. Moreover, developing novel and appropriate therapeutic approaches will contribute to the suitable management of the pandemic. Therefore, there is an urgent necessity to make comprehensive investigations and study reviews about COVID-19, offering the latest findings of novel therapies, drugs, epidemiology, and routes of virus transmission and pathogenesis. In this review, we discuss new therapeutic outcomes and cover and the most significant aspects of COVID-19, including the epidemiology, biological features, organs failure, and diagnostic techniques.

Vertical transmission and kidney damage in newborns whose mothers had coronavirus disease 2019 during pregnancy.

OBJECTIVES: Coronavirus disease 2019 (COVID-19) has become a worldwide pandemic. However, the hazard to newborns in pregnancy remains controversial. The aim of this study was to investigate the vertical transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from mother to child and developmental toxicity in the fetus. METHODS: All clinical information was recorded on 22 neonates born to mothers with confirmed COVID-19 pneumonia in Tongji Hospital. RESULTS: The average birth weight of the 22 newborns (16 males and 6 females) was 2980 g, and the mean gestational week was 37W+3. The birth weight of three babies was <2500 g, and the gestational week of all three low-birth-weight neonates was less than 36W. Three newborns had minor lesions of infection in the lungs as shown by computed tomography (CT) scans. Furthermore, three newborns had elevated SARS-CoV-2-related immunoglobin M (IgM) antibodies, and 11 newborns (52.4%) had positive immunoglobin G (IgG) antibodies. Notably, both cystatin C and ß2-microglobulin were increased in all newborns. Five of the 21 tested newborns had leukocytosis, and 11 had increased neutrophil levels. In addition, the aspartate aminotransferase of 18 newborns and the γ-glutamyl transpeptidase of 19 newborns were increased. Total bilirubin was elevated in all newborns and serum albumin was reduced in 20 of 22 newborns. CONCLUSIONS: This study was the first to discover that COVID-19 infection in the third trimester of pregnancy could cause fetal kidney developmental injury, as indicated by increased cystatin C and ß2-microglobulin in all neonates. Furthermore, there is the possibility of maternal-fetal transmission of SARS-CoV-2.

Congenital SARS-CoV-2 Infection in a Neonate With Severe Acute Respiratory Syndrome.

Coronavirus disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is mainly transmitted through droplets, but other ways of transmission have been hypothesized. We report a case of vertical transmission of SARS-CoV-2 in a preterm born to an infected mother, confirmed by the presence of the virus in the neonatal blood, nasopharyngeal and oropharyngeal swabs collected in the first half an hour of life. The neonate presented with acute respiratory distress, similar to the findings in severely affected adults. This case highlights the importance of pregnancy, labor and neonatal period surveillance of affected mothers and their newborns.

Comparison of three automatic chemiluminescent immunoassays for monitoring dynamic profile of SARS-CoV-2 IgG and IgM.

BACKGROUND: Seldom performance evaluation and diagnosis comparison studies were reported for different chemiluminescent immunoassay (CLIA) kits approved under an emergency approval program for SARS-CoV-2 infection. METHODS: A total of 100 and 105 serum separately from non-infected populations and COVID-19 patients were detected with SARS-CoV-2 IgM and IgG kits. The characteristics including precision, functional sensitivity, linearity, and accuracy were evaluated for Axceed, iFlash, and Maglumi CLIA kits. RESULTS: Maglumi and iFlash had the best analytical sensitivity for IgM and IgG, respectively. Axceed kits had a linearity response in the detected concentration. The clinical sensitivity of Axceed, iFlash, and Maglumi was 68.0%, 64.9%, and 63.9% with a specificity of 99.0%, 96.0%, and 100% for IgM, 85.6%, 97.9%, and 94.8% with a specificity of 97.0% for IgG. ROC analysis indicated all kits had a diagnostic power greater than 0.9. Notably, either IgM or IgG kits obtained a poor agreement (Kappa value from 0.397 to 0.713) with others. Among 38 recovered patients, 94.7% had an effective immune response, and both seropositive IgM and IgG accounted for the biggest proportion (medium, 42 days onset), then followed by the single seropositive IgG (medium, 50 days onset) in Ab profile. CONCLUSION: The performance of CLIA kits satisfied the diagnosis of SARS-CoV-2 infection. Both positive of IgG and IgM contributes to improve the specificity, and a positive one will enhance the sensitivity.

Immunity and coagulation and fibrinolytic processes may reduce the risk of severe illness in pregnant women with coronavirus disease 2019.

BACKGROUND: There are specific physiological features regarding the immunity and coagulation among pregnant women, which may play important roles in the development of coronavirus disease 2019. OBJECTIVE: This study aimed to determine the key factors associated with the deterioration of patients with coronavirus disease 2019 and the differentiating clinical characteristics of pregnant women with coronavirus disease 2019 to interfere with the progression of coronavirus disease 2019. STUDY DESIGN: A retrospective study of 539 Chinese Han adult patients with coronavirus disease 2019 was conducted, of which 36 cases were pregnant women. In addition, 36 pregnant women without coronavirus disease 2019 were recruited as the control. The characteristics of severe and critical illnesses, which were differentiated from mild and moderate illnesses in patients with coronavirus disease 2019, were analyzed using a machine learning algorithm. In addition, major differences between pregnant women with coronavirus disease 2019 and age-matched nonpregnant women with severe or critical coronavirus disease 2019, paired with pregnant women without coronavirus disease 2019, were explored to identify specific physiological features of pregnant women with coronavirus disease 2019. RESULTS: For the total patient population, the lymphocyte, CD3+, CD4+, CD8+, CD19+, and CD16+CD56+ cell counts were significantly lower, and white blood cell count, neutrophil count, and neutrophil-to-lymphocyte ratio were higher in those with severe or critical illness than those with mild or moderate illness (P<.001). The plasma levels of interleukin-6, interleukin-10, and interleukin-6-to-interleukin-10 ratio were significantly increased in patients with critical illness compared with patients with mild, moderate, and severe illnesses (P<.001). The above immunologic coclusters achieved an area under the receiver operating characteristic curve of 0.801 (95% confidence interval, 0.764-0.838), and its combined model with the coagulation and fibrinolysis indices (prothrombin time, D-dimer) achieved an area under the receiver operating characteristic curve of 0.815 (95% confidence interval, 0.779-0.851) using the random forest regression model to predict severe or critical illness. For pregnant women with coronavirus disease 2019, none had preexisting diseases. Compared with nonpregnant women with mild or moderate coronavirus disease 2019, pregnant women with coronavirus disease 2019 displayed increased white blood cell count, neutrophil count, neutrophil-to-lymphocyte ratio, and levels of D-dimer and fibrinogen, along with decreased lymphocyte and interleukin-4 levels (P<.05). Although they presented similar changes of immunologic markers of lymphocyte; white blood cell count; neutrophil-to-lymphocyte ratio; CD3+, CD4+, CD8+, and CD16+CD56+ cell counts; and interleukin-6-to-interleukin-10 ratio, compared with nonpregnant women with severe or critical coronavirus disease 2019, none of the pregnant women with coronavirus disease 2019 deteriorated into severe or critical illness. There was no significant difference in white blood cell count, lymphocyte count, neutrophil count, neutrophil-to-lymphocyte ratio, immunologic markers, or coagulation and fibrinolysis markers between pregnant women with coronavirus disease 2019 and pregnant women without coronavirus disease 2019. As for the discrepancy of pathophysiological features between pregnant women with coronavirus disease 2019 and nonpregnant women with severe or critical coronavirus disease 2019, the immunologic markers achieved an area under the receiver operating characteristic curve of 0.875 (95% confidence interval, 0.773-0.977), and its combined model with coagulation and fibrinolysis indices achieved an area under the receiver operating characteristic curve of 0.931 (95% confidence interval, 0.850-1.000). CONCLUSION: Immune dysregulation was identified as a crucial feature of patients with coronavirus disease 2019, which developed severe or critical illness, and pregnant women with coronavirus disease 2019 presented with similar immune responses but rarer incidences of severe or critical illness. Immune dysregulation is related to the risks of deterioration into severe or critical illness. The specific coagulation and fibrinolysis systems of pregnancy may reduce the risk of pregnant women with coronavirus disease 2019 without preexisting disease from developing severe illness.

Elevated liver enzimes induced by COVID-19 in pregnancy / Elevación de enzimas hepáticas inducida por COVID-19 en embarazada

INTRODUCCIÓN: Las alteraciones del perfil hepático durante el embarazo ocurren en 3-5% de las gestantes. Una nueva etiología que se ha presentado en el contexto de pandemia actual es el síndrome respiratorio agudo severo relacionado con el nuevo coronavirus (SARS-CoV-2). Éste es responsable de alteraciones hepáticas en 2 a 11% de la población general infectada por este virus, y de hasta un 30% en las embarazadas que se infectan con SARS-CoV-2. Con el objetivo de mostrar una presentación poco frecuente del SARS-CoV-2 se expone un caso clínico de elevación de transaminasas en embarazada inducida por este nuevo virus. CASO CLÍNICO: Paciente de 36 años, cursando embarazo de 20+6 semanas, consulta por dolor abdominal asociado a ictericia y coluria. Se solicita estudio donde destaca elevación de transaminasas. Ecografía abdominal con vía biliar fina. Se descartan diferentes etiologías de hepatitis aguda y crónica (dada la falta de antecedentes). Finalmente se solicita PCR para COVID-19 que resulta positiva. CONCLUSIÓN: Luego de un estudio exhaustivo de diferentes etiologías de elevación de transaminasas, se atribuye esta alteración enzimática a SARS-CoV-2. Se decide seguimiento ambulatorio estricto con pruebas hepáticas cada dos semanas. La paciente evoluciona estable con exámenes normales luego de un mes desde que se indica el alta hospitalaria. Después de descartar etiologías frecuentes de elevación de transaminasas durante el embarazo, sugerimos solicitar el estudio de este virus con PCR para COVID-19, ya que podría ser una presentación poco frecuente de SARS-CoV-2.

INTRODUCTION: Approximately 3-5% of women present alterations of hepatic enzymes during pregnancy. Under the new circumstances that the world is facing with the SARS-COV2 pandemic, a new etiology for hepatic enzyme alterations has risen. The severe acute respiratory syndrome that the novel coronavirus causes is responsible for hepatic enzyme alterations in 2 to 11% of the sick population that did not have a previous underlying hepatic condition. Furthermore, hepatic enzyme alterations in pregnant women infected with SARS-COV2 presents in up to 30% of the cases. An infrequent presentation of SARS-COV2 is presented as our clinical case. CLINICAL CASE: A 36-year-old patient with a 20+6 week pregnancy presents abdominal pain, jaundice and choluria. General blood workup shows elevated transaminases. The abdominal ultrasound revealed a thin bile duct. Acute and chronic hepatitis etiologies were discarded. Finally, a PCR of COVID-19 was solicited, which turned out to be positive. CONCLUSIÓN: After an exhaustive study to determine the etiology of the elevated transaminases, the hepatic alterations were attributed to SARS-COV2 infection. A conservative management was adopted, with outpatient follow-up with liver testing every two weeks. The patient progresses with a stable steady decline in hepatic enzyme levels, and one-month post hospital discharge, her transaminases had reached normal values. Based on this clinical case, after ruling out frequent etiologies for elevated transaminases during pregnancy, it seems reasonable to request a PCR for COVID-19, since it could be a rare presentation of SARS-CoV-2.

SARS-COV-2 infection during pregnancy, a risk factor for eclampsia or neurological manifestations of COVID-19? Case report.

BACKGROUND: There are no published cases of tonic-clonic seizures and posterior bilateral blindness during pregnancy and Severe Acute Respiratory Syndrome (SARS) Coronavirus (COV) 2 (SARS-COV-2) infection. We do not just face new and unknown manifestations, but also how different patient groups are affected by SARS-COV-2 infection, such as pregnant women. Coronavirus Disease 2019 (COVID-19), preeclampsia, eclampsia and posterior reversible leukoencephalopathy share endothelium damage and similar pathophysiology. CASE PRESENTATION: A 35-year-old pregnant woman was admitted for tonic-clonic seizures and SARS-COV-2 infection. She had a normal pregnancy control and no other symptoms before tonic-clonic seizures development. After a Caesarean section (C-section) she developed high blood pressure, and we initiated antihypertensive treatment with labetalol, amlodipine and captopril. Few hours later she developed symptoms of cortical blindness that resolved in 72 h with normal brain computed tomography (CT) angiography. CONCLUSION: The authors conclude that SARS COV-2 infection could promote brain endothelial damage and facilitate neurological complications during pregnancy.
