RESUMO
Background & Purpose: Pregnant women are at higher risk of developing severe COVID-19 compared with non-pregnant women, particularly in the third trimester1. Despite ongoing campaigns, the proportion of pregnant women vaccinated against SARS-CoV-2 is lower than in the general population2. The medium-term effects of COVID-19 during pregnancy are not well characterized. We report a cohort of pregnant women admitted to hospital with moderate-to-severe COVID-19. Method(s): Data from clinical records were retrospectively collected from all pregnant women admitted through the maternity assessment unit at St. Thomas' Hospital, between January 2021 and January 2022, due to COVID-19 requiring oxygen to maintain saturations >94%. Result(s): Fourteen women were identified (age=33.4+/-5.2 years;42.8% Caucasian;28.6% Black), requiring admission at 31+/-4.7 weeks gestation. Only two were double vaccinated (14.2%). Body mass index (BMI) was 27.2+/-6.4 kg/m2. Two women had concomitant co-morbidities (asthma and type 1 diabetes). They were managed in the obstetric high- dependency unit (level 1), barring one that required invasive ventilation for one day. The Delta variant was most commonly implicated (43%). All women requiring oxygen received steroids. Four women received Tocilizumab and three casirivimab/imdevimab;two received both. Four women were delivered by emergency Caesarean section due to maternal or fetal concerns, while the others continued their pregnancies. There was one late intrauterine death at 35 weeks. Women were followed-up for an average of six weeks. At follow-up in the obstetric medicine COVID-19 clinic, all women had complete resolution of COVID-19 on clinical examination, pulse oximetry and chest radiograph. Conclusion(s): In 14 pregnant women requiring admission to hospital for hypoxia secondary to moderate-to-severe COVID-19, concomitant co-morbidities and high BMI were not prevalent. Most were not vaccinated against SARS-CoV-2. Despite experiencing moderate-to-severe COVID-19, they had complete clinical and radiological resolution at six weeks follow-up.
RESUMO
Background: Myasthenia gravis (MG) is an autoimmune disorder leading to variable degrees of skeletal muscle weakness. During pregnancy, infections can trigger exacerbations and should be treated promptly and aggressively.(1) Sotrovimab is a monoclonal antibody used as monotherapy in high-risk, symptomatic non-hospitalized patients at risk of developing COVID-19 disease. (2) It is thought to have retained activity against SARS-CoV-2 omicron variant. (3) Limited data are available on its use in pregnancy. Case: A 39-year-old woman with severe generalized MG, was referred to our joint neuro-obstetric multidisciplinary service. Her two previous pregnancies were complicated by severe exacerbations of MG necessitating intensive care admissions, and preterm labour. Her long-term therapy included high dose steroids, intravenous immune globulin (IVIG) and plasma exchanges. In this pregnancy, she additionally received rituximab in the first-trimester, allowing her prednisolone to be weaned to 20 mg daily, with ongoing 3-weekly IVIG. She received 3 doses of the Pfizer COVID-19 vaccine. At 19 weeks she developed mild coryzal symptoms, sore throat and myalgia. Lateral flow and polymerase chain reaction tests in the community confirmed infection with SARS-CoV-2. She was treated with sotrovimab with uneventful recovery at home. At 31 weeks, she again tested positive for SARS-CoV-2, after reporting mild COVID-19 symptoms. She received a second dose of sotrovimab and had a quick recovery. Subsequent SARS-CoV-2 genotyping indicated she had contracted the Omicron-BA.2 variant. Fetal surveillance for growth (SARS-CoV-2) and arthrogryposis (MG) did not raise concerns. At 35+3 weeks, she went into spontaneous labour and was delivered by caesarean section for evolving chorioamnionitis, with uneventful recovery for mother and baby. Discussion(s): We report a case of repeated treatment with sotrovimab (in second and third trimesters) of a high-risk, non-hospitalized pregnant woman, who was re-infected with SARS-CoV-2. We identified no immediate maternal, fetal or neonatal complications following two doses of sotrovimab for mild COVID-19.
