BACKGROUND: Clinical presentations of coronavirus disease 2019 (COVID-19) among children with asthma have rarely been investigated. This study aimed to assess clinical manifestations and outcome of COVID-19 among children with asthma, and whether the use of asthma medications was associated with outcomes of interest.

METHODS: The Global Asthma Network (GAN) conducted a global survey among GAN centers. Data collection was between November 2020 and April 2021.

RESULTS: Fourteen GAN centers from 10 countries provided data on 169 children with asthma infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 was asymptomatic in 58 (34.3%), mild in 93 (55.0%), moderate in 14 (8.3%), and severe/critical in 4 (2.4%). Thirty-eight (22.5%) patients had exacerbation of asthma and 21 (12.4%) were hospitalized for a median of 7 days (interquartile range 3-16). Those who had moderate or more severe COVID-19 were significantly more likely to have exacerbation of asthma as compared to those who were asymptomatic or had mild COVID-19 (adjusted odds ratio (adjOR) 3.97, 95% CI 1.23-12.84). Those who used inhaled bronchodilators were significantly more likely to have a change of asthma medications (adjOR 2.39, 95% CI 1.02-5.63) compared to those who did not. Children who used inhaled corticosteroids (ICS) did not differ from those who did not use ICS with regard to being symptomatic, severity of COVID-19, asthma exacerbation, and hospitalization.

CONCLUSIONS: Over dependence on inhaled bronchodilator may be inappropriate. Use of ICS may be safe and should be continued in children with asthma during the pandemic of COVID-19.
