Asemptomatik gebe kadınlarda COVID-19 taraması: Hangisi daha iyi; rektal mi orofaringeal / nazofaringeal sürüntü mü?

Abstract

Aim: The aim of the study was to evaluate the incidence of asymptomatic COVID-19 disease in pregnant women withrectal and oropharyngeal/nasopharyngeal swab to compare the efficacy of two samples.Material and Method: This prospective cohort study included 234 asymptomatic pregnant women who had undergoneplanned cesarean section between May 7 and September 24, 2020 in obstetrics unit of a tertiary care center, in Ankara,Turkey. The oropharyngeal/nasopharyngeal swab, rectal swab, placental, amniotic fluid, and cord blood samples wereobtained from all participants. The placental, amniotic fluid, and cord blood samples were tested when any of theoropharyngeal/nasopharyngeal or rectal samples were positive. The real-time reverse transcriptase-polymerase chainreaction (RT-PCR) test was performed to detect SARS-CoV-2 virus in the samples.Results: The incidence of the asymptomatic COVID-19 disease was 0.42% (1/234) in the study population. One of 234oropharyngeal/nasopharyngeal swabs was positive, while none of the rectal swabs including the one positive withoropharyngeal/nasopharyngeal swab were positive for SARS-CoV-2 virus. The RT-PCR test results of the placental,amniotic fluid, and cord blood samples of the COVID-positive case were negative.Conclusion: The incidence of asymptomatic COVID-19 disease in pregnant women who had undergone elective cesareandelivery was low, in Ankara, Turkey. In asymptomatic pregnant women, oropharyngeal/nasopharyngeal swab was foundto be more useful in detecting COVID-19 disease compared to rectal swab. No evidence was found about the intrauterinetransmission of asymptomatic disease.
