    Outcomes Following Extracorporeal Membrane Oxygenation for Severe COVID-19 in Pregnancy or Post Partum
    (American Medical Association, 2023-05-01) Byrne, John J.; Shamshirsaz, Amir A.; Cahill, Alison G.; Turrentine, Mark A.; Seasely, Angela R.; Eid, Joe; Rouse, Caroline E.; Richley, Michael; Raghuraman, Nandini; Naqvi, Mariam; El-Sayed, Yasser Y.; Badell, Martina L.; Cheng, CeCe; Liu, James; Adhikari, Emily H.; Patel, Soha S.; O'Neil, Erika R.; Ramsey, Patrick S.; Obstetrics and Gynecology, School of Medicine
    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.

    Treatment for Mild Chronic Hypertension during Pregnancy
    (Massachusetts Medical Society, 2022) Tita, Alan T.; Szychowski, Jeff M.; Boggess, Kim; Dugoff, Lorraine; Sibai, Baha; Lawrence, Kirsten; Hughes, Brenna L.; Bell, Joseph; Aagaard, Kjersti; Edwards, Rodney K.; Gibson, Kelly; Haas, David M.; Plante, Lauren; Metz, Torri; Casey, Brian; Esplin, Sean; Longo, Sherri; Hoffman, Matthew; Saade, George R.; Hoppe, Kara K.; Foroutan, Janelle; Tuuli, Methodius; Owens, Michelle Y.; Simhan, Hyagriv N.; Frey, Heather; Rosen, Todd; Palatnik, Anna; Baker, Susan; August, Phyllis; Reddy, Uma M.; Kinzler, Wendy; Su, Emily; Krishna, Iris; Nguyen, Nicki; Norton, Mary E.; Skupski, Daniel; El-Sayed, Yasser Y.; Ogunyemi, Dotum; Galis, Zorina S.; Harper, Lorie; Ambalavanan, Namasivayam; Geller, Nancy L.; Oparil, Suzanne; Cutter, Gary R.; Andrews, William W.; Chronic Hypertension and Pregnancy (CHAP) Trial Consortium; Obstetrics and Gynecology, School of Medicine
    Background: The benefits and safety of the treatment of mild chronic hypertension (blood pressure, <160/100 mm Hg) during pregnancy are uncertain. Data are needed on whether a strategy of targeting a blood pressure of less than 140/90 mm Hg reduces the incidence of adverse pregnancy outcomes without compromising fetal growth. Methods: In this open-label, multicenter, randomized trial, we assigned pregnant women with mild chronic hypertension and singleton fetuses at a gestational age of less than 23 weeks to receive antihypertensive medications recommended for use in pregnancy (active-treatment group) or to receive no such treatment unless severe hypertension (systolic pressure, ≥160 mm Hg; or diastolic pressure, ≥105 mm Hg) developed (control group). The primary outcome was a composite of preeclampsia with severe features, medically indicated preterm birth at less than 35 weeks' gestation, placental abruption, or fetal or neonatal death. The safety outcome was small-for-gestational-age birth weight below the 10th percentile for gestational age. Secondary outcomes included composites of serious neonatal or maternal complications, preeclampsia, and preterm birth. Results: A total of 2408 women were enrolled in the trial. The incidence of a primary-outcome event was lower in the active-treatment group than in the control group (30.2% vs. 37.0%), for an adjusted risk ratio of 0.82 (95% confidence interval [CI], 0.74 to 0.92; P<0.001). The percentage of small-for-gestational-age birth weights below the 10th percentile was 11.2% in the active-treatment group and 10.4% in the control group (adjusted risk ratio, 1.04; 95% CI, 0.82 to 1.31; P = 0.76). The incidence of serious maternal complications was 2.1% and 2.8%, respectively (risk ratio, 0.75; 95% CI, 0.45 to 1.26), and the incidence of severe neonatal complications was 2.0% and 2.6% (risk ratio, 0.77; 95% CI, 0.45 to 1.30). The incidence of any preeclampsia in the two groups was 24.4% and 31.1%, respectively (risk ratio, 0.79; 95% CI, 0.69 to 0.89), and the incidence of preterm birth was 27.5% and 31.4% (risk ratio, 0.87; 95% CI, 0.77 to 0.99). Conclusions: In pregnant women with mild chronic hypertension, a strategy of targeting a blood pressure of less than 140/90 mm Hg was associated with better pregnancy outcomes than a strategy of reserving treatment only for severe hypertension, with no increase in the risk of small-for-gestational-age birth weight.
