SARS-CoV-2: Do corticosteroids for fetal lung maturation worsen maternal or fetal outcomes?

Abstract

Immune system changes during pregnancy could make pregnant women more susceptible to SARS-Cov-2 infection.The use of corticosteroids within obstetrics has been shown to reduce the risks of respiratory distress syndrome, intraventricular haemorrhage, necrotizing enterocolitis and neonatal death in the baby associated with premature delivery. During the COVID-19 pandemic, corticosteroids have been trialled as a treatment to dampen the 'cytokine storm' and associated inflammatory processes. Corticosteroids have long been known to have immunosuppressive effects that could hinder the body's ability to mount a defence against COVID-19 and thereby delaying viral clearance. In this clinical case studies, antenatal steroids for fetal lung maturation appear to be of benefit and did not result in a deterioration of maternal disease. Our clinical case studies support the current recommendations from the Royal College of Obstetricians and Gynaecologists ie corticosteroids for fetal lung maturation is appropriate in patients who are suspected or have confirmed SARSCoV-2 infection
