Abstract

Purpose Pregnant and postpartum women are at increased risk of developing severe COVID-19. Monoclonal antibodies (mAbs) are now widely used in high-income countries to treat mild to moderate COVID-19 outpatients at risk for developing severe disease. Very few data are available on the use of mAbs in special populations, including pregnant and postpartum women. Here we present our early experience with mAbs in these two populations. Methods Electronic records of pregnant and postpartum women treated with mAbs at Careggi University Hospital, Florence, were retrieved. Relevant data were extracted (age, presence of risk factors for COVID-19, oxygen support, mAb type, gestational age, and pregnancy status). When available, outcomes at 28 days after administration were also included. Results From March 1st to September 30th 2021, eight pregnant and two postpartum women have been treated with mAbs at our center. The median age was 31 years (IQR 30-33.5, range 29-38), median gestational age was 24 weeks. Seven patients had additional risk factors. According to the Italian disposition, all patients received casirivimab/imdevimab, with five receiving a 2.4 mg dose and five receiving a 8 g dose. Eight patients improved. One developed myocarditis, considered a COVID-19 complication. Another required a transient increase of low flow oxygen support before improving and being discharged. At a 28 days follow-up, all patients were clinically recovered. We did not observe mAbs related adverse events. Conclusion Although preliminary data should be interpreted with caution, it is remarkable how mAbs were well tolerated by pregnant women with COVID-19. Further data on mAbs in this special population should be collected but the use of mAbs in pregnant and postpartum patients should be considered. Even thus oral antivirals are becoming available, they are not recommended in pregnant and postpartum women. This population may specifically benefit from treatment with last generation mAbs.
