Apnea or cyanosis as COVID-19 initial presentation in newborns.

The clinical manifestation of coronavirus disease 2019 (COVID-19) infection in newborns varies from asymptomatic infection to severe illness. Apnea or cyanosis as the earliest symptoms is rarely mentioned. The aim of this study is to describe the characteristics of newborns with COVID-19 infection admitted to the neonatal intensive care unit considering cyanosis or apnea as a form of presentation. This is a descriptive observational study with retrospectively collected data. All neonates under 30 days old and preterm infants with corrected gestational age of 44 weeks who had confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with a positive antigen or reverse transcriptase polymerase chain reaction (RT-PCR) test and who were attended to between March 2020 and March 2022 were included. During the two years of the study, 410 patients were admitted to the neonatal unit. Twenty-six patients (6.3%) presented with confirmed SARS-CoV-2 infection. The main clinical characteristic at admission was apnea in 55% and cyanosis in 45%. Of the 11 patients admitted with this presentation, eight were diagnosed with COVID-19 acute upper respiratory disease, and three met the definition of COVID-19 bronchiolitis. A large proportion of the patients had a mild infection (65%, n = 17), 31% (n = 8) had a severe infection and only one patient had a critical infection, accounting for 4%. Apnea and cyanosis can be a manifestation of SARS-CoV-2 infection in newborns, which suggests the need to include it in the diagnostic workup as other viral respiratory infections.
