Abstract

Aim: The aim of the study was to evaluate the incidence of asymptomatic COVID-19 disease in pregnant women with rectal 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 undergone planned 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 were obtained from all participants. The placental, amniotic fluid, and cord blood samples were tested when any of the oropharyngeal/nasopharyngeal or rectal samples were positive. The real-time reverse transcriptase-polymerase chain reaction (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 234 oropharyngeal/nasopharyngeal swabs was positive, while none of the rectal swabs including the one positive with oropharyngeal/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 cesarean delivery was low, in Ankara, Turkey. In asymptomatic pregnant women, oropharyngeal/nasopharyngeal swab was found to be more useful in detecting COVID-19 disease compared to rectal swab. No evidence was found about the intrauterine transmission of asymptomatic disease.

Özet

Amaç: Çalışmanın amacı, rektal ve orofaringeal / nazofaringeal sürüntü ile gebelerde asemptomatik COVID-19 hastalık insidansını değerlendirerek iki yöntemin etkinliğini karşılaştırmaktı. Gereç ve Yöntem: Bu prospektif kohort çalışmasına, Ankara'da üçüncü basamak bir merkezin obstetri ünitesinde 7 Mayıs-24 Eylül 2020 tarihleri arasında planlı sezaryen yapılan 234 asemptomatik gebe dahil edildi. Tüm katılımcılardan orofaringeal / nazofaringeal sürüntü, rektal sürüntü, plasental, amniyotik sıvı ve kordon kanı örnekleri alındı. Orofaringeal / nazofaringeal veya rektal örneklerden herhangi biri pozitif olduğunda plasental, amniyotik sıvı ve kordon kanı örnekleri test edildi. Örneklerdeki SARS-CoV-2 virüsünü tespit etmek için gerçek zamanlı ters transkriptaz-polimeraz zincir reaksiyonu (RT-PCR) testi yapıldı. Bulgular: Asemptomatik COVID-19 hastalık insidansı çalışma popülasyonunda % 0,42 (1/234) idi. 234 orofaringeal / nazofaringeal sürüntüden biri pozitif iken, orofaringeal / nazofaringeal sürüntü ile pozitif olan dahil rektal sürüntülerin hiçbiri SARS-CoV-2 virüsü için pozitif değildi. COVID pozitif olgunun plasental, amniyotik sıvı ve kordon kanı örneklerinin RT-PCR testi sonuçları negatifti. Sonuç: Ankara'da elektif sezaryen ile doğum yapmış gebelerde asemptomatik COVID-19 hastalığı insidansı düşüktü. Asemptomatik hamile kadınlarda, orofaringeal / nazofaringeal sürüntü rektal sürüntü ile karşılaştırıldığında COVID-19 hastalığını tespit etmede daha yararlı bulundu. Asemptomatik hastalığın intrauterin geçişine dair bir kanıt bulunamadı.
