Effects of Covid-19 Vaccination during Pregnancy on the Obstetric and Neonatal Outcomes in a Tertiary Health Care Center.

BACKGROUND: Pregnancy is an immuno-compromised state, and pregnant women with COVID-19 are at an increased risk for adverse pregnancy outcomes. Thus, the Center for Disease Control and Prevention (CDC) and the Advisory Committee on Immunization (ACIP) have advocated for COVID-19 vaccination in pregnant women. COVAXIN and COVISHIELD were the vaccines being used in India in the first phase of vaccination, but limited data exist on pregnancy outcomes regarding SARS-CoV-2 vaccines and pregnancy and lactation. MATERIAL AND METHODS: A retrospective study was conducted which included only women who delivered after 24 weeks gestation. Women with an unknown vaccination status or with past or active COVID-19 infection were excluded. Demographic characteristics, maternal and obstetric outcomes, and fetal and neonatal outcomes were compared between the unvaccinated and vaccinated groups. Statistical analysis was done with Chi-square testing and the Fisher exact test using SPSS-26 software. RESULTS: Deliveries before a gestation of 37 weeks were significantly higher in the unvaccinated group compared to the vaccinated group. Rates of vaginal deliveries and preterm deliveries were found to be higher in the unvaccinated population. Women who had taken COVAXIN had a higher rate of adverse events compared to those who had taken COVISHIELD. CONCLUSION: There were no significant differences in adverse obstetric outcomes attributed to vaccine administration between the vaccinated and unvaccinated pregnant women. The beneficial effects of the vaccines in protecting against COVID-19 infection, particularly in pregnancy, outweigh the minor adverse events associated with vaccine administration.

Persistent renal replacement requirement following fulminant psittacosis infection in pregnancy.

Chlamydia psittaci is a zoonotic bacterial infection that most commonly causes mild flu-like symptoms in humans. However, in pregnancy, it can present as fulminant psittacosis associated with systemic illness, disseminated intravascular coagulation, renal and hepatic failure. We describe a case of a veterinary nurse in her 30s who presented at 32 weeks' gestation with rapidly progressive multiorgan failure, with positive, C. psittaci serology. Further history revealed that she had delivered a number of dead lambs in the preceding weeks to her illness, highlighting the importance of a thorough social history. C. psittaci should be suspected in the differential as a causative organism for severe pneumonia with multiorgan failure particularly in pregnant women with animal or bird contacts.

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.

Assessing the added value of group B Streptococcus maternal immunisation in preventing maternal infection and fetal harm: population surveillance study.

OBJECTIVE: To assess the incidence of maternal group B Streptococcus (GBS) infection in England. DESIGN: Population surveillance augmented through data linkage. SETTING: England. POPULATION: All pregnant women accessing the National Health Service (NHS) in England. METHODS: Invasive GBS (iGBS) infections during pregnancy or within 6 weeks of childbirth were identified by linking Public Health England (PHE) national microbiology surveillance data for 2014 to NHS hospital admission records. Capsular serotypes of GBS were determined by reference laboratory typing of clinical isolates from women aged 15-44 years. Post-caesarean section surgical site infection (SSI) caused by GBS was identified in 21 hospitals participating in PHE SSI surveillance (2009-2015). MAIN OUTCOME MEASURES: iGBS rate per 1000 maternities; risk of GBS SSI per 1000 caesarean sections. RESULTS: Of 1601 patients diagnosed with iGBS infections in England in 2014, 185 (12%) were identified as maternal infections, a rate of 0.29 (95% CI 0.25-0.33) per 1000 maternities and representing 83% of all iGBS cases in women aged 18-44 years. Seven (3.8%) were associated with miscarriage. Fetal outcome identified excess rates of stillbirth (3.4 versus 0.5%) and extreme prematurity (<28 weeks of gestation, 3.7 versus 0.5%) compared with national averages (P < 0.001). Caesarean section surveillance in 27 860 women (21 hospitals) identified 47 cases of GBS SSI, with an estimated 4.24 (3.51-5.07) per 1000 caesarean sections, a median time-to-onset of 10 days (IQR 7-13 days) and ten infections that required readmission. Capsular serotype analysis identified a diverse array of strains with serotype III as the most common (43%). CONCLUSIONS: Our assessment of maternal GBS infection in England indicates the potential additional benefit of GBS vaccination in preventing adverse maternal and fetal outcomes.

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.

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.

Distinguishing Features Common to Dual Fatal Herpes Simplex Virus Infections That Occur in Both a Pregnant Woman and Her Newborn Infant.

Deaths from herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2) are rare. A major exception is perinatally acquired HSV-1 or HSV-2 infection where the neonatal death rate is substantial. Fatal HSV infection also occurs occasionally in pregnant women. The goal of this review is to enumerate the reports that describe dual deaths of both a pregnant woman and her newborn from a herpesvirus infection. A total of 15 reports were found in the medical literature, of which five described pregnant women with HSV encephalitis and 10 described women with disseminated HSV infection. When the virus was typed, most cases of dual mother/newborn deaths were caused by HSV-2. Of interest, in two situations caused by HSV-1, the pregnant woman probably acquired her primary HSV-1 infection from one of her children and not by sexual transmission. Complete genomic sequencing was performed on one set of HSV-1 isolates collected from mother (blood) and newborn (blood and skin). The mother's strain and the newborn's skin strain were 98.9% identical. When the newborn's two strains were compared, they were 97.4% identical. Only one mother was tested by the HerpeSelect IgG antibody kit. During the nine days of her undiagnosed disseminated infection preceding her death, her serology was negative. In summary, although dual mother/newborn deaths from HSV infection are rare, they continue to be reported as recently as 2017.

Maternal Diet, Infection, and Risk of Cord Blood Inflammation in the Bangladesh Projahnmo Pregnancy Cohort.

Inflammation may adversely affect early human brain development. We aimed to assess the role of maternal nutrition and infections on cord blood inflammation. In a pregnancy cohort in Sylhet, Bangladesh, we enrolled 251 consecutive pregnancies resulting in a term livebirth from July 2016-March 2017. Stillbirths, preterm births, and cases of neonatal encephalopathy were excluded. We prospectively collected data on maternal diet (food frequency questionnaire) and morbidity, and analyzed umbilical cord blood for interleukin (IL)-1α, IL-1ß, IL-6, IL-8 and C-reactive protein. We determined associations between nutrition and infection exposures and cord cytokine elevation (≥75% vs. <75%) using logistic regression, adjusting for confounders. One-third of mothers were underweight (BMI < 18.5 kg/m2) at enrollment. Antenatal and intrapartum infections were observed among 4.8% and 15.9% of the sample, respectively. Low pregnancy intakes of B vitamins (B1, B2, B3, B6, B9 (folate)), fat-soluble vitamins (D, E), iron, zinc, and linoleic acid (lowest vs. middle tertile) were associated with higher risk of inflammation, particularly IL-8. There was a non-significant trend of increased risk of IL-8 and IL-6 elevation with history of ante-and intrapartum infections, respectively. In Bangladesh, improving micronutrient intake and preventing pregnancy infections are targets to reduce fetal systemic inflammation and associated adverse neurodevelopmental outcomes.

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.

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.

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.

Association of low birth weight and polyparasitic infection during pregnancy in Lambaréné, Gabon.

OBJECTIVE: To report the prevalence of polyparasitism during pregnancy in the Lambaréné region of Gabon and its association with newborn birth weight. METHOD: Pregnant women in their third trimester were recruited in a prospective study between November 2011 and March 2015. Parasite infection status was assessed microscopically in stool, urine and blood samples. Maternal demographic and obstetrical characteristics and newborns anthropometric data were collected. Multivariable logistic regression was used to assess the association between low birth weight and polyparasitism. RESULTS: 678 of 927 pregnant women were included for analysis with mean age (SD) of 25 (6.8) years. The analysis showed that 69% (468/678) were infected with at least one parasite (Plasmodium spp., Schistosoma spp., soil-transmitted helminths, filarial infections). This comprised of 38% with monoparasitism and 31% polyparasitism. The proportion of newborn babies with a weight below 2500 g (LBW) in our study was 21% (142/678). Compared to pregnant women without infection, women with monoparasitic infection had adjusted Odds Ratio confidence interval 95% CI (aOR [95%CI]) of 1.6 [0.95-2.73], those with two parasites had aOR 95%CI of 2.63 [1.51-4.62], and those with more than two parasites had aOR of 5.08 [2.5-10.38] for delivering a newborn with low birth weight. CONCLUSION: In Lambaréné, an endemic area for multiple parasite infections, there is a high prevalence of polyparasitism in pregnant women. Polyparasitism is associated with low birth weight. Therefore, there is an urgent need for active screening and treatment of parasite infections in pregnant women to assess the potential public health benefit of such interventions.

Vaginal microbiota in pregnant women with inflammatory rheumatic and inflammatory bowel disease: A matched case-control study.

BACKGROUND: Rheumatic diseases and vaginal infections both increase the risk of preterm birth. It is unclear whether pregnant women with rheumatic disease are more likely to experience vaginal infections, which might potentially accumulate modifiable risk factors. OBJECTIVE: In this study, we sought to evaluate the vaginal microbiota of pregnant women with inflammatory rheumatic and inflammatory bowel disease. METHODS: A total of 539 asymptomatic women with singleton pregnancy were routinely screened for an abnormal vaginal microbiota between 10 + 0 and 16 + 0 gestational weeks. Vaginal smears were Gram-stained and microscopically analysed. Those with inflammatory diseases (with or without immunomodulatory therapy) were assigned to the case group and matched in a 1:3 ratio to healthy pregnant controls. RESULTS: Overall, an abnormal vaginal microbiota occurred more frequently among women of the case group, compared with those of the control group (33.8% vs 15.6%; 95% CI: 1.78-4.27, p < .001). In particular, Candida colonisation (22.3% vs 9.2%; 95% CI: 1.69-4.75, p < .001), but also bacterial vaginosis (14.9% vs 7.2%; 95% CI: 1.25-4.1, p = .006), occurred more often in the case than in the control group. No significant difference was found with regard to the occurrence of an abnormal vaginal microbiota between subgroups with and without immunomodulatory treatment (37.0% vs 27.1%; 95% CI: 0.29-1.35, p = .232). CONCLUSION: Pregnant women with inflammatory rheumatic and inflammatory bowel disease are at risk for bacterial vaginosis and Candida colonisation, which might pose a risk for preterm birth. Prospective studies are needed to further evaluate the influence of autoimmune conditions and immunosuppressive therapy on the vaginal microbiota.

Zika-exposed microcephalic neonates exhibit higher degree of inflammatory imbalance in cerebrospinal fluid.

Not every neonate with congenital Zika virus (ZIKV) infection (CZI) is born with microcephaly. We compared inflammation mediators in CSF (cerebrospinal fluid obtained from lumbar puncture) between ZIKV-exposed neonates with/without microcephaly (cases) and controls. In Brazil, in the same laboratory, we identified 14 ZIKV-exposed neonates during the ZIKV epidemic (2015-2016), 7(50%) with and 7(50%) without microcephaly, without any other congenital infection, and 14 neonates (2017-2018) eligible to be controls and to match cases. 29 inflammation mediators were measured using Luminex immunoassay and multidimensional analyses were employed. Neonates with ZIKV-associated microcephaly presented substantially higher degree of inflammatory perturbation, associated with uncoupled inflammatory response and decreased correlations between concentrations of inflammatory biomarkers. The groups of microcephalic and non-microcephalic ZIKV-exposed neonates were distinguished from the control group (area under curve [AUC] = 1; P < 0.0001). Between controls and those non-microcephalic exposed to ZIKV, IL-1ß, IL-3, IL-4, IL-7 and EOTAXIN were the top CSF markers. By comparing the microcephalic cases with controls, the top discriminant scores were for IL-1ß, IL-3, EOTAXIN and IL-12p70. The degree of inflammatory imbalance may be associated with microcephaly in CZI and it may aid additional investigations in experimental pre-clinical models testing immune modulators in preventing extensive damage of the Central Nervous System.
