Increased risk of early-onset preeclampsia in pregnant women with COVID-19.

OBJECTIVE: To estimate incidence, risk of early and late-onset preeclampsia (PE) and understand their relationship with severity of COVID-19. METHODS: Pregnant women with COVID-19 (n = 1929) were enrolled from 1 April 2020 to 24 February 2022. Primary outcome measure was incidence and risk of early onset PE in women with COVID-19. RESULTS: The incidence of early and late-onset PE was 11.4% and 5.6%. Moderate to severe COVID-19 was associated with eight times higher risk of early onset PE [aOR = 8.13 (1.56-42.46), p = 0.0129] compared to asymptomatic group. CONCLUSIONS: Risk of early onset PE was higher in pregnant women with symptomatic COVID-19 as compared to asymptomatic women.
