Safety of Remdesivir in 20 Children with COVID-19-Case Series

Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) virus, has spread worldwide since 2019. Several studies report that adult patients hospitalized with severe COVID-19 can be treated successfully with remdesivir (RDV). However, few studies report the safety and efficacy of RDV for children. This study included 20 hospitalized patients who were diagnosed with COVID-19 and received RDV at Kobe Children's Hospital, Japan, between February and June, 2022. The median age was 2 years (IQR, 1-11 years; range, 5 months to 19 years). Twelve (60%) patients were male. Three (15%) patients were previously healthy, whereas the other 17 had at least one underlying medical condition: five (25%) patients had respiratory disease, four (20%) had cardiac disease, three (15%) had central nervous system disease, four (20%) had hematologic or oncologic disease, and two (10%) had a chromosomal abnormal. All patients recovered without any sequelae, and no serious adverse events were reported. The adverse events were elevated liver enzymes in 4 children (20%), leukopenia (5%), neutropenia (5%), and hypokalemia (5%). Our study may show that the use of RDV for COVID-19 in children led to no serious adverse events.
