ABSTRACT
OBJECTIVE:
To describe the proportions of asymptomatic, mild and severe diseases in infected pregnant women admitted for delivery. To compare maternal, fetal and neonatal outcomes of SARS-CoV-2 infected pregnant women with those of non-infected patients. STUDYDESIGN:
Through an universal PCR testing for SARS-COV-2 at admission (not symptoms-based), this prospective cohort study enrolled all pregnant women admitted for delivery between 16th of June and the 16th of August 2020 in the West French Guiana Hospital Center.RESULTS:
507 pregnant women were included during the study period, of which 137 (27 %) were infected with SARS-COV-2. On admission, only 34/137 (24.8 %) of these patients presented with clinical symptoms. Among asymptomatic women, 16 /103 (15 %) became symptomatic after diagnosis. Throughout the delivery hospitalization and follow-up, 87/137 (63.5 %) remained always asymptomatic, 45/137 (32.8 %) developed a mild COVID-19 and 5/137 (3.6 %) developed a severe infection. SARS-CoV-2 infected patients were more likely to have post-partum hemorrhage >500 mL (14.2 % vs 7.2 %, RR 2.0 [95 %CI 1.1-3.4]), to be transfused (5.5 % vs 1.1 %, RR 4.9 [1.5-16.6]), and to be hospitalized in ICU (3.6 % vs 0.8 %, RR 4.5 [95 %CI 1.1-18.6] than uninfected ones. Intra-uterine fetal demises were more common in infected mothers compared to controls (5.1 % vs 1.1 %, RR 4.7 [95 % CI 1.4-45.9). Among 108 neonates from infected mothers tested at birth, none tested positive (0/108). When tested between 25 and 42 h after delivery, 4/29 (13.7 %) were positive for SARS-CoV-2 RT-PCR on nasopharyngeal swabs and remained asymptomatic.CONCLUSION:
Pregnant women admitted for delivery and diagnosed with a SARS-COV-2 infection through an universal screening were symptomatic in only a quarter of cases. Their risks of post-partum hemorrhage, transfusion and admission to ICU were higher than those of uninfected patients. They also presented a higher risk of intra-uterine fetal demise. There were no other differences in maternal, obstetrical or neonatal outcomes.Keywords
