Severe form of COVID-19 in a neonate with resuscitated cardio-respiratory arrest - Case presentation

SARS-CoV-2 infection is usually a self-limiting viral infection in healthy children. Still, it’s effects on the neonatal population remain largely unknown. There has been evidence of adverse events on neonates, mostly consisting in case reports of patients with severe forms of COVID-19 and also recent cohort studied of the pediatric population including the neonatal subgroup. The clinical presentation appears different in the neonatal patients in contrast with older children, and may manifest also as a life-threatening respiratory infection with systemic complications. In this paper we present a clinical case of a premature boy with a corrected age of 40 weeks at admission to the Pediatric Infectious Diseases Clinical Department IX of the National Institute of Infectious Diseases “Prof. Dr. Matei Bals” with the diagnosis of SARS-CoV-2 infection. The positive diagnosis was established on suggestive clinical picture (fever, dry couch, rhinorrhea, loose stools and inappetence) and confirmed by SARS-CoV-2 rapid antigen test. Laboratory investigations at admission showed only moderate to severe anemia, mild inflammatory syndrome and a mild neonatal hyperbilirubinemia, with normal leukocyte count, normal glycaemia, ionograme and blood gases. Chest x-ray showed moderate interstitial pneumonia. In the second day of admission, after 24h of favorable evolution, with no fever and present appetite, he suddenly presented during defecation a presumptive vasovagal syndrome, with general hypotonia and a short period of desaturation. Laboratory investigations made during the episode showed normal glycaemia, normal ionograme, normal blood gases, moderate-severe anemia and important metabolic acidosis. A new chest x-ray showed evolution of the interstitial pneumonia. We did a blood transfusion and continued antiviral treatment, antibiotic treatment and perfusions. He maintained normal pulmonary and cardiac function for another 6 hours, after which he presented a tonic-clonic seizure and after administration of intrarectal benzodiazepines he presented cardio-pulmonary arrest. He was resuscitated, intubated and sedated and transfer to a children ICU. 2 weeks later after admission in the ICU he was discharged with favorable outcome. The case presented shows that although SARS-CoV-2 infection is often a mild condition in children, COVID-19 in neonates can have an unpredicted course. Rapid evolution to sever forms can be a possible disease outcome. Preterm birth with associated c
