Introduction: Pregnant patients with COVID-19 are at an increased risk of several maternal and neonatal complications. At the beginning of the pandemic in Peru, universal screening in obstetric patients was performed with SARS-CoV-2 antibody. There is limited knowledge about the risk of preeclampsia in seropositive pregnant people prior to vaccination. Our objective was to evaluate the association between seropositivity in unvaccinated patients and risk of preeclampsia. Materials and methods: We conducted a retrospective cohort study of pregnant patients admitted from August 1st to September 30th, 2020. We included adult patients admitted in labor who had an antibody test taken. Patients were classified into seropositive groups: IgG+, IgM+, or both IgG+ and IgM+. Our primary outcome was the prevalence of preeclampsia. Bivariate and multivariable analyses were performed. Results: Four hundred and forty patients were included in the study. Of these, 275 were negative, and 165 were positive for SARS-CoV-2 antibodies. Seropositivity was not associated with higher rates of preeclampsia (p=0.183), or with preeclampsia with severe features (p=0.916) even after adjusting for maternal age> 35, BMI≥ 30, nulliparity, and previous history of preeclampsia, and type of serologic status (IgG+, IgM+, and IgG+IgM+). Previous preeclampsia had the greatest association with development of preeclampsia (OR=13.40 95% IC [4.98-36.09]; p<0.05), and with preeclampsia with severe features (OR=5.46 95% IC [1.65-18.02]; p< 0.05). Conclusions: We found that in an obstetric population during the first 6 months of the pandemic there was no association between SARS-CoV-2 antibody status and the risk of preeclampsia at time of delivery.
