RESUMO
OBJECTIVE: Among patients ≥45 years, the birth rate in the United States continues to increase. As fertility declines with age, this cohort often utilizes assisted reproductive technology, specifically in vitro fertilization (IVF). While both advancing maternal age and IVF are independently associated with adverse maternal outcomes, data regarding their additive effect are scant. This article aims to determine if patients who conceive via IVF are at increased risk for preterm birth (PTB) compared to patients with non-IVF pregnancies in a very advanced maternal age (vAMA) cohort (≥45 years). STUDY DESIGN: Retrospective cohort study of all pregnant patients ≥45 years old who delivered at a single institution (2014-2021). Those with incomplete delivery/neonatal records or multiples beyond twins were excluded. We compared individuals who conceived via IVF to those who conceived without IVF. The primary outcome was preterm delivery <37 weeks gestation. Secondary outcomes included other adverse perinatal outcomes. Using multivariable logistic regression, we adjusted for multiple gestation as well as confounders found to be significantly different in the univariable analysis and other known risk factors for PTB. RESULTS: In our study cohort of 420 vAMA patients, individuals who underwent IVF were more likely to be older, privately insured, nulliparous, and with a twin gestation. The PTB rate in vAMA patients who underwent IVF was 24.4 compared to 8.4% in patients who did not use IVF (p < 0.001). After adjusting for confounders, IVF was an independent risk factor for PTB <37 weeks in vAMA patients (adjusted odds ratio {aOR] = 4.3, 95% confidence interval [CI]: 1.7-10.4, p = 0.001). In vitro fertilization was also associated with a composite of adverse maternal outcomes (hypertensive disorder of pregnancy, postpartum hemorrhage, blood transfusion, and unplanned hysterectomy) (aOR 1.7, 95% CI [1.1-2.9], p = 0.03). CONCLUSION: In the vAMA population, conception via IVF is associated with an increased risk of PTB <37 weeks. KEY POINTS: · This study examines IVF as an independent risk factor for PTB in patients ≥45 years at delivery, which has not been specifically addressed in prior studies.. · In vAMA patients, use of IVF is associated with an increased risk of PTB <37 weeks. These patients also have higher rates of cesarean delivery. Neonates from IVF pregnancies are more likely to be very low birth weight or low birth weight.. · Bodies of research exist for both advanced maternal age and assisted reproductive technology, there is a paucity of data specifically in parturients of vAMA who conceive via IVF..
RESUMO
BACKGROUND: Personal-device-based point-of-care-ultrasound (P-POCUS) probes plug directly into a cell phone or tablet to function as its display, creating the potential to increase access to obstetric ultrasonography in complex healthcare settings (COVID units, low resource settings); however, new technology must be proven to be reliable in the obstetric setting before integrating into practice. OBJECTIVE: To evaluate the intraclass correlation (reliability) of personal-device-based-point-of-care-ultrasound devices as compared with standard ultrasound machines in obstetrics. STUDY DESIGN: This was a prospective, observational study of patients between 19-39 weeks gestation in an urban, prenatal ultrasound diagnosis center. Each patient underwent assessment by an expert sonographer using standard ultrasound machines and personal-device-based-point-of-care-ultrasound devices to determine estimated fetal weight. The statistical reliability and agreement between the estimated fetal weights was assessed through intraclass correlation coefficients, Bland-Altman plots, and Pearson correlation coefficients. RESULTS: 100 paired sets of scans were performed from October 2020 to December 2020. For the estimated fetal weights, there was near-perfect agreement, with an intraclass correlation coefficient of 0.99 (P<.0001). Bland-Altman analysis showed an average difference of 53 grams, with 95% limit of agreement between -178 grams and 283 grams. Pearson correlation showed near-perfect correlation between the measurements (r=0.99, P<.0001). CONCLUSION: personal-device-based point-of-care-ultrasound devices are reliable tools for performing basic obstetrical ultrasound and have the potential to increase access to obstetrical ultrasound worldwide.

OBJECTIVE: This study aimed to assess whether a prolonged second stage of labor is an independent predictor of obstetric anal sphincter injury (OASI) in a contemporary cohort of nulliparous and term parturients, and to evaluate whether predelivery factors can accurately predict OASI. STUDY DESIGN: This was a nested case-control study within a cohort of consecutive nulliparous term parturients with a singleton gestation who underwent a vaginal delivery at a single institution between January 2014 and January 2015. Cases were defined as women with a third- or fourth-degree laceration at the time of delivery, and controls were women without a third- or fourth-degree laceration. A prolonged second stage was defined as a second stage of ≥3 hours. Univariable and multivariable regression analyses were performed to examine the relationship between prolonged second stage of labor and third- or fourth-degree lacerations. Receiver operator curves were developed to assess the predictive capacity of predelivery information for third- and fourth-degree lacerations. RESULTS: Of 1,197 births, 63 women had third- or fourth-degree lacerations (5.3%). With each additional hour of the second stage, the rate of OASI increased, with 2.9% of women with a second stage of <1 hour with OASI, 3.5% between 1 and 2 hours, 5.7% between 2 and 3 hours, 7.8% between 3 and 4 hours, 16.1% between 4 and 5 hours, and 28.6% among women with a second stage length >5 hours (p < 0.001). In multivariable regression analysis, operative vaginal delivery (adjusted odds ratio [aOR] = 5.92, 95% confidence interval [CI]: 3.17-11.07) and a prolonged second stage (aOR = 1.92, 95% CI: 1.06-3.51) were independent predictors of third- and fourth-degree lacerations. A predictive model was developed from these results (area under the curve [AUC] = 0.75, 95% CI: 0.68-0.81). CONCLUSION: Prolonged second stage of labor is a predictor of OASI, after adjustment for operative vaginal delivery. A model using predelivery risk factors has a reasonable prediction of OASI. KEY POINTS: · Prolonged second stage labor is associated with obstetric anal sphincter injury in term nulliparas.. · Predelivery risk factors reasonably predict obstetric anal sphincter injury in term nulliparas.. · Improved models are needed for clinical risk-stratification..

BACKGROUND: Remdesivir is efficacious for severe coronavirus disease 2019 (COVID-19) in adults, but data in pregnant women are limited. We describe outcomes in the first 86 pregnant women with severe COVID-19 who were treated with remdesivir. METHODS: The reported data span 21 March to 16 June 2020 for hospitalized pregnant women with polymerase chain reaction-confirmed severe acute respiratory syndrome coronavirus 2 infection and room air oxygen saturation ≤94% whose clinicians requested remdesivir through the compassionate use program. The intended remdesivir treatment course was 10 days (200 mg on day 1, followed by 100 mg for days 2-10, given intravenously). RESULTS: Nineteen of 86 women delivered before their first dose and were reclassified as immediate "postpartum" (median postpartum dayâ 1 [range, 0-3]). At baseline, 40% of pregnant women (median gestational age, 28 weeks) required invasive ventilation, in contrast to 95% of postpartum women (median gestational age at delivery 30 weeks). By day 28 of follow-up, the level of oxygen requirement decreased in 96% and 89% of pregnant and postpartum women, respectively. Among pregnant women, 93% of those on mechanical ventilation were extubated, 93% recovered, and 90% were discharged. Among postpartum women, 89% were extubated, 89% recovered, and 84% were discharged. Remdesivir was well tolerated, with a low incidence of serious adverse events (AEs) (16%). Most AEs were related to pregnancy and underlying disease; most laboratory abnormalities were grade 1 or 2. There was 1 maternal death attributed to underlying disease and no neonatal deaths. CONCLUSIONS: Among 86 pregnant and postpartum women with severe COVID-19 who received compassionate-use remdesivir, recovery rates were high, with a low rate of serious AEs.

OBJECTIVE: This study estimates the association of a first trimester finding of subchorionic hematoma (SCH) with third trimester adverse pregnancy outcomes in women with twin pregnancies. STUDY DESIGN: Retrospective cohort study of twin pregnancies prior to 14 weeks at a single institution from 2005 to 2019, all of whom had a first trimester ultrasound. We excluded monoamniotic twins, fetal anomalies, history of fetal reduction or spontaneous reduction, and twin-to-twin transfusion syndrome. Ultrasound data were reviewed, and we compared pregnancy outcomes after 24 weeks in women with and without a SCH at their initial ultrasound 60/7 to 136/7 weeks. Regression analysis was used to control for any differences in baseline characteristics. RESULTS: A total of 760 women with twin pregnancies met inclusion criteria for the study, 68 (8.9%) of whom had a SCH. Women with SCH were more likely to have vaginal bleeding and had their initial ultrasound at earlier gestational ages. On univariate analysis, SCH was not significantly associated with gestational age at delivery, preterm birth, birthweight of either twin, low birthweight percentiles of either twin, fetal demise, or preeclampsia. SCH was associated with placental abruption on univariate analysis, but not after controlling for vaginal bleeding and gestational age at the time of the initial ultrasound (adjusted odds ratio: 2.00, 95% confidence interval: 0.63-6.42). Among women with SCH, SCH size was not associated with adverse pregnancy outcomes. CONCLUSION: In women with twin pregnancies, the finding of a first trimester SCH is not associated with adverse pregnancy outcomes >24 weeks.

PURPOSE: We report a case of a pregnant female presenting with pituitary apoplexy and simultaneous SARS-CoV-2 infection with a focus on management decisions. CLINICAL HISTORY: A 28-year-old G5P1 38w1d female presented with 4 days of blurry vision, left dilated pupil, and headache. She tested positive for SARS-CoV-2 on routine nasal swab testing but denied cough or fever. Endocrine testing demonstrated an elevated serum prolactin level, and central hypothyroidism. MRI showed a cystic-solid lesion with a fluid level in the pituitary fossa and expansion of the sella consistent with pituitary apoplexy. Her visual symptoms improved with corticosteroid administration and surgery was delayed to two weeks after her initial COVID-19 infection and to allow for safe delivery of the child. A vaginal delivery under epidural anesthetic occurred at 39 weeks. Two days later, transsphenoidal resection of the mass was performed under strict COVID-19 precautions including use of Powered Air Purifying Respirators (PAPRs) and limited OR personnel given high risk of infection during endonasal procedures. Pathology demonstrated a liquefied hemorrhagic mass suggestive of pituitary apoplexy. She made a full recovery and was discharged home two days after surgery. CONCLUSION: Here we demonstrate the first known case of successful elective induction of vaginal delivery and transsphenoidal intervention in a near full term gravid patient presenting with pituitary apoplexy and acute SARS-CoV-2 infection. Further reports may help determine if there is a causal relationship or if these events are unrelated. Close adherence to guidelines for caregivers can greatly reduce risk of infection.

OBJECTIVE: This study was aimed to compare maternal and neonatal outcomes between women with twin pregnancies who underwent induction of labor with those women who had planned Cesarean delivery (CD). STUDY DESIGN: This is a retrospective cohort study of women with twin pregnancies ≥ 24 weeks with an indication for delivery but not in labor. Two groups were examined, women who underwent induction and women who underwent planned CD. Maternal and neonatal outcomes were compared between groups both for deliveries at gestational age ≥ 37 weeks and < 37 weeks. RESULTS: A total of 453 patients were included. Overall, 212 (46.8%) women underwent induction and 241 (53.2%) underwent planned CD. Women who underwent induction of labor had a high rate of VD, both in the term and preterm groups (69.8 and 73.6%, respectively). Women who underwent induction of labor had reduced maternal length of stay, neonatal length of stay, and blood loss, without any increase in adverse outcomes. Neonatal ventilation of either twin delivered < 37 weeks was higher in the CD compared with induction group (27.5 vs. 9.4%, p < 0.01), but this was not significant on adjusted odds ratio analysis (aOR = 0.71, 95% CI: 0.19-2.66). CONCLUSION: Labor induction in twin gestations have improved maternal outcomes and similar neonatal outcomes compared with planned CD.

OBJECTIVE: To compare maternal morbidity between women undergoing delivery of twins who intend to labor with those women who do not intend to labor. STUDY DESIGN: This was a retrospective cohort study of women undergoing delivery of twins in a single maternal-fetal medicine practice between January 2005 and February 2018. We identified women with a twin delivery at gestational age ≥24 weeks and determined if they intended or did not intend to labor. Maternal outcomes were compared between the groups. RESULTS: A total of 788 patients were included, of whom 404 (51.3%) intended to labor and 384 (48.7%) did not intend to labor. Women who intended to labor had a high rate of vaginal delivery (VD; 79.7%). Overall, 45 (5.7%) women required blood transfusion; this was not significantly different between the groups (6.2 vs. 5.2%, p = 0.54). Women who intended to labor had a shorter hospital stay and lower blood loss. There were no significant differences for all other maternal outcomes. CONCLUSION: In patients undergoing twin delivery, women who intend to labor have similar maternal morbidity compared with women who do not intend to labor. This supports current guidelines recommending providers offer a trial of VD for twin pregnancies.

OBJECTIVE: To estimate the time to delivery after elective cerclage removal and evaluate whether there is a difference based on the indication for cerclage placement. STUDY DESIGN: This was a retrospective cohort of singleton pregnancies that underwent Shirodkar cerclage placement at a single maternal-fetal medicine practice between June 2005 and June 2017. We included all scheduled elective cerclage removals >36 weeks. The primary outcome was latency to delivery. We further compared time to delivery based on the original indication for cerclage. Data were analyzed using the one-way analysis of variance and chi-square test. RESULTS: A total of 143 patients met the inclusion criteria. Of these, 40.6% were history indicated, 51.0% ultrasound indicated, and 8.4% exam indicated. The mean time from removal to delivery was 13.3 ± 8.4 days; 12.6% (18/136) of patients delivered within 24 hours of removal. When stratified by indication for cerclage, there were no significant differences for all delivery outcomes. Delaying cerclage removal to >37 weeks resulted in a statistically significantly later gestational age at delivery compared with removal between 36 and 366/7 weeks (39.0 vs. 38.3 weeks, p = 0.001). CONCLUSION: The mean time from elective Shirodkar cerclage removal to delivery is 13 days with only 12.6% of patients delivering within 24 hours of removal.

OBJECTIVE: To study the offer and uptake of chromosomal microarray analysis (CMA) among women undergoing invasive prenatal testing. METHODS: This is a retrospective cohort study of women who underwent chorionic villus sampling (CVS) or amniocentesis. Charts were reviewed for CMA offer and uptake, in additional to clinical and demographic variables. RESULTS: One hundred forty-one women underwent CVS (n = 53) or amniocentesis (n = 91) over the study period. Overall, 41% of women underwent CMA. Women who underwent invasive testing for a fetal structural abnormality were more likely to undergo CMA than women who underwent invasive testing for all other indications (aOR 43.18, 95% CI 4.64 - 401.58). Chromosomal microarray was offered more often to women who primarily spoke English (p < 0.001), self-identified as white (p = 0.046) and did not receive prenatal care in a community health center (p = 0.044). Statistically significant differences in CMA uptake by race/ethnicity, language, insurance or provider type were not noted. Multiparous women were less likely to accept this test than nulliparas (aOR 0.39, 95% CI 0.17 - 0.86). CONCLUSION: Women who undergo invasive fetal testing are more likely to undergo CMA if the indication is for a fetal structural anomaly. There may be important demographic disparities in the offering of CMA which bear further exploration. © 2016 John Wiley & Sons, Ltd.

Emergency cerclage refers to a cerclage placed during the second trimester in a woman noted to have painless cervical dilation. Although randomized-controlled trials are limited, observational studies suggest an improvement in neonatal outcomes in selected patients undergoing an emergency cerclage. Labor and chorioamniontis are contraindications for cerclage placement. Advanced dilation (>3 to 4 cm) and a later gestational age (22 to 24 wk) are associated with poorer outcomes. This chapter reviews the indications, outcomes and perioperative management strategies for cerclage placement in this setting.

With the advent of routine obstetrical ultrasound, the diagnosis of an adnexal mass in pregnancy has become increasingly common. Although the reported incidence and expected clinical course varies based on the gestational age at the time of diagnosis and the criteria used to define an adnexal mass, the majority of adnexal masses diagnosed in pregnancy are benign and are likely to resolve without complication or intervention. This review will discuss the epidemiology of adnexal masses in pregnancy, diagnostic tools, potential complications, and management options during pregnancy.

OBJECTIVE: The aim of this article is to determine the risk of maternal chorioamnionitis and neonatal morbidity in women with preterm premature rupture of membranes (PPROM) exposed to one corticosteroid course versus a single repeat corticosteroid steroid course. STUDY DESIGN: Secondary analysis of a cohort of women with singleton pregnancies and PPROM. The primary outcome was a clinical diagnosis of maternal chorioamnionitis. Using multivariate logistic regression, we controlled for maternal age, race, body mass index, diabetes, gestational age at membrane rupture, preterm labor, and antibiotic administration. Neonatal morbidities were compared between groups controlling for gestational age at delivery. RESULTS: Of 1,652 women with PPROM, 1,507 women received one corticosteroid course and 145 women received a repeat corticosteroid course. The incidence of chorioamnionitis was similar between groups (single course = 12.3% vs. repeat course = 11.0%; p = 0.8). Women receiving a repeat corticosteroid course were not at increased risk of chorioamnionitis (adjusted odds ratio, 1.28; 95% confidence interval, 0.69-2.14). A repeat course of steroids was not associated with an increased risk of any neonatal morbidity. CONCLUSION: Compared with a single steroid course, our findings suggest that the risk of maternal chorioamnionitis or neonatal morbidity may not be increased for women with PPROM receiving a repeat corticosteroid course.

BACKGROUND: Activity restriction is a common recommendation given to patients during pregnancy for various indications, despite lack of definitive data showing improvements in pregnancy outcomes. OBJECTIVE: To determine if activity restriction (AR) in pregnancy is associated with decreased odds of adverse pregnancy outcomes (APOs). STUDY DESIGN: Secondary analysis of the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (nuMoM2b) prospective cohort. Nulliparous singletons were followed at 8 sites from October 2010 - September 2013. Demographic and clinical data were collected at 4 timepoints, and participants were surveyed about AR recommendations at 22w0d-29w6d and delivery. We excluded participants missing data on AR and age. Participants were grouped according to history of AR, and APOs included: gestational hypertension (gHTN), preeclampsia/eclampsia, preterm birth (PTB), and small for gestational age (SGA) neonate. Associations between AR and APOs were examined using uni- and multivariable logistic regression models adjusting for a priori identified APO risk factors. RESULTS: Of 10,038 nuMoM2b participants, 9,312 met inclusion criteria and 1,386 (14.9%) were recommended AR; participants identifying as Black [aOR 0.81 (95% CI 0.68-0.98)] or Hispanic [aOR 0.73 (95% CI 0.61-0.87)] were less likely to be placed on AR when compared to those identifying as White. Overall, 3,197 (34.3%) experienced at least one APO [717 (51.7%) of participants with AR compared to 2,480 (31.3%) participants without AR]. After adjustment for baseline differences, the AR group had increased odds of gHTN [aOR 1.61 (95% CI 1.35-1.92)], preeclampsia/eclampsia [aOR 2.52 (95% CI 2.06-3.09)] and iatrogenic and spontaneous PTB [aOR 2.98 (95% CI 2.41-3.69)], but not delivery of an SGA neonate. CONCLUSION: AR in pregnancy was independently associated with increased odds of hypertensive disorders of pregnancy and PTB, but future prospective work is needed to determine potential causality. Further, participants identifying as Black or Hispanic were significantly less likely to be recommended AR compared to those identifying as White. While AR is not an evidence-based practice, these findings suggest bias may impact which patients receive advice to limit activity in pregnancy.
RESUMO
OBJECTIVE: COVID-19 vaccination is a key approach to reduce morbidity and mortality in pregnant patients and their newborns. Anti-vaccine sentiment has recently increased with unclear impact on pregnant patients. We examined the association between acceptance of tetanus-diphtheria-acellular pertussis (Tdap) and influenza vaccines, considered to be routine pregnancy vaccines, and COVID-19 vaccine acceptance. Secondarily, we identified other predictors of COVID-19 vaccine uptake and described pregnancy outcomes in patients who were and were not vaccinated during pregnancy. METHODS: A retrospective cohort study of all patients who delivered at a single site from December 2020 - March 2022. Demographic, pregnancy, neonatal, and vaccination data were abstracted from the electronic medical record, which imports vaccine history from the California Immunization Registry. The relationship between influenza and Tdap vaccine acceptance, other baseline characteristics, and COVID-19 vaccine uptake was assessed using univariable and multivariable regression analysis. RESULTS: Of the 7857 patients who delivered during the study period, 4410 (56.1%) accepted the COVID-19 vaccine. Of those who received the COVID-19 vaccine, 3363 (97.6%) and 3049 (88.5%) received influenza and Tdap vaccines, respectively. Patients were more likely to receive the COVID-19 vaccine if they had advanced maternal age, obesity, Asian race, and private insurance. After adjustment for baseline differences, COVID vaccine acceptance was associated with receipt of Tdap (aOR 2.10, 95% CI 1.90-2.33) and influenza vaccines (aOR 2.83, 95% CI 2.55-3.14). There were no differences in preterm birth, low birthweight, and NICU admission between patients who received and did not receive the COVID-19 vaccine. CONCLUSION: Patients were more likely to accept COVID-19 vaccination if they received Tdap or influenza vaccinations. Older age, obesity, Asian race, and private insurance were independent predictors of vaccine uptake. Disparities in COVID-19 vaccination uptake bear further exploration to guide efforts in equitable and widespread vaccine distribution.

Importance: Existing reports of pregnant patients with COVID-19 disease who require extracorporeal membrane oxygenation (ECMO) are limited, with variable outcomes noted for the maternal-fetal dyad. Objective: To examine maternal and perinatal outcomes associated with ECMO used for COVID-19 with respiratory failure during pregnancy. Design, Setting, and Participants: This retrospective multicenter cohort study examined pregnant and postpartum patients who required ECMO for COVID-19 respiratory failure at 25 hospitals across the US. Eligible patients included individuals who received care at one of the study sites, were diagnosed with SARS-CoV-2 infection during pregnancy or up to 6 weeks post partum by positive nucleic acid or antigen test, and for whom ECMO was initiated for respiratory failure from March 1, 2020, to October 1, 2022. Exposures: ECMO in the setting of COVID-19 respiratory failure. Main outcome and measures: The primary outcome was maternal mortality. Secondary outcomes included serious maternal morbidity, obstetrical outcomes, and neonatal outcomes. Outcomes were compared by timing of infection during pregnancy or post partum, timing of ECMO initiation during pregnancy or post partum, and periods of circulation of SARS-CoV-2 variants. Results: From March 1, 2020, to October 1, 2022, 100 pregnant or postpartum individuals were started on ECMO (29 [29.0%] Hispanic, 25 [25.0%] non-Hispanic Black, 34 [34.0%] non-Hispanic White; mean [SD] age: 31.1 [5.5] years), including 47 (47.0%) during pregnancy, 21 (21.0%) within 24 hours post partum, and 32 (32.0%) between 24 hours and 6 weeks post partum; 79 (79.0%) had obesity, 61 (61.0%) had public or no insurance, and 67 (67.0%) did not have an immunocompromising condition. The median (IQR) ECMO run was 20 (9-49) days. There were 16 maternal deaths (16.0%; 95% CI, 8.2%-23.8%) in the study cohort, and 76 patients (76.0%; 95% CI, 58.9%-93.1%) had 1 or more serious maternal morbidity events. The largest serious maternal morbidity was venous thromboembolism and occurred in 39 patients (39.0%), which was similar across ECMO timing (40.4% pregnant [19 of 47] vs 38.1% [8 of 21] immediately postpartum vs 37.5% postpartum [12 of 32]; P > .99). Conclusions and Relevance: In this multicenter US cohort study of pregnant and postpartum patients who required ECMO for COVID-19-associated respiratory failure, most survived but experienced a high frequency of serious maternal morbidity.

Uterine necrosis is an infrequent event and is most commonly reported as a complication of interventions for postpartum haemorrhage management. Cases of uterine necrosis in pregnancy are rare. The mainstay of treatment for uterine necrosis is hysterectomy, and the data regarding conservative management are limited. A gravida 3, para 2 presented at 33 weeks gestation with ovarian torsion and underwent an exploratory laparotomy with ovarian cystectomy. The surgery was complicated by excess bleeding, which was controlled with the placement of sutures along the uterine body. She had multiple subsequent presentations for severe abdominal pain without clear aetiology. Four weeks after the initial surgery, she underwent caesarean delivery, at which time uterine necrosis was diagnosed. Her uterus was preserved. She received postoperative intravenous antibiotics and was closely observed. She continued to do well 10 months postpartum. In patients with uterine necrosis during pregnancy who are haemodynamically stable, conservative management may be an option.

PROBLEM: We evaluated eculizumab, a complement protein C5 inhibitor, for treatment of severe COVID-19 in pregnant and postpartum individuals. METHOD OF STUDY: Protocol ECU-COV-401 (clinicaltrials.gov NCT04355494) is an open label, multicenter, Expanded Access Program (EAP), evaluating eculizumab for treatment of severe COVID-19. Participants enrolled at our center from August 2020 to February 2021. Hospitalized patients were eligible if they had severe COVID-19 with bilateral pulmonary infiltrates and oxygen requirement. Eculizumab was administered on day 1 (1200 mg IV) with additional doses if still hospitalized (1200 mg IV on Days 4 and 8; 900 mg IV on Days 15 and 22; optional doses on Days 12 and 18). The primary outcome was survival at Day 15. Secondary outcomes included survival at Day 29, need for mechanical ventilation, and duration of hospital stay. We evaluated pharmacokinetic and pharmacodynamic data, safety, and adverse outcomes. RESULTS: Eight participants were enrolled at the Cedars-Sinai Medical Center, six during pregnancy (mean 30 ± 4.0 weeks) and two in the postpartum period. Baseline oxygen requirement ranged from 2 L/min nasal cannula to 12 L/min by non-rebreather mask. The median number of doses of eculizumab was 2 (range 1-3); the median time to hospital discharge was 5.5 days (range 3-12). All participants met the primary outcome of survival at Day 15, and all were alive and free of mechanical ventilation at Day 29. In three participants we demonstrated that free C5 and soluble C5b-9 levels decreased following treatment. There were no serious adverse maternal or neonatal events attributed to eculizumab at 3 months. CONCLUSION: We describe use of eculizumab to treat severe COVID-19 in a small series of pregnant and postpartum adults. A larger, controlled study in pregnancy is indicated.

BACKGROUND: For unvaccinated individuals with mild-to-moderate coronavirus disease 2019 (COVID-19), monoclonal antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) decrease the risk of severe disease and hospitalization. We describe the use of the monoclonal antibodies casirivimab and imdevimab for COVID-19 in pregnancy. CASE: Two unvaccinated pregnant individuals presented with moderate COVID-19, one in the second trimester and one in third trimester; both met criteria for outpatient management. To decrease the risk for severe disease, they were treated with casirivimab and imdevimab. Neither experienced an adverse drug reaction, and neither progressed to severe disease. CONCLUSION: Monoclonal antibodies such as casirivimab and imdevimab, approved under an emergency use authorization, should be considered in unvaccinated pregnant individuals with mild-to-moderate COVID-19 to decrease the risk of severe disease.
