Pharmacotherapy of Acute COVID-19 Infection and Multisystem Inflammatory Syndrome in Children: Current State of Knowledge

摘要

The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic is a health care emergency across the world. Although mitigation measures, such as social distancing and face masks, have attempted to slow the spread of the infection, cases continue to rise. Children who are otherwise healthy tend to develop a milder acute Coronavirus disease 2019 (COVID-19) infection and have lower mortality rates compared with adults. There are 6 published pediatric series that included 252 children with acute COVID-19 infection and describe various treatments and outcomes. Guidelines recommend treating pediatric patients similarly to adult patients. Currently, no prophylactic drug therapy has been shown to reduce the spread of infection. Treatment options for acute COVID-19 are limited to remdesivir and glucocorticoids for patients who require oxygen and/or mechanical ventilation. The efficacy of hydroxychloroquine, chloroquine, and azithromycin has not been proven and their safety has been a concern. Other therapies that are being explored include interleukin (IL)-1 and IL-6 inhibitors. In children, an atypical Kawasaki-like disease emerged after recent exposure to SARS-CoV-2 and has been named Multisystem Inflammatory Syndrome in Children (MIS-C). Nine case series, including 418 pediatric patients, described pharmacotherapies used and patient outcomes. These pharmacotherapies included intravenous immune globulin and glucocorticoids and in some patients, IL-1 and IL-6 inhibitors. Given the paucity of data in children, this article presents currently recommended pharmacotherapies for the treatment of acute COVID-19 infection in adult patients and whenever available, in pediatric patients. Pharmacotherapies used in the treatment of MIS-C in children are also reviewed.
