Comparison of clinical features of COVID-19 infection in children with asthma and their healthy peers

Abstract

Aim: We aimed to assess the impact of COVID-19 on asthma exacerbations and to compare the severity of symptoms of SARS-CoV-2 infection of asthmatic children with those of healthy children.

Methods: The clinical course of COVID-19 was compared among 89 children with asthma and 84 healthy children with age- and gender-matched. Demographic factors, severity of asthma, duration of asthma, presence of atopy, type of treatment, and compliance to treatment in asthmatic children on clinical course of infection and to determine the risk factors for severe course for asthma exacerbation during COVID-19 were evaluated retrospectively. Demographic characteristics, clinical symptoms, duration of complaints, and hospitalization rates were statistically compared between the two groups.

Results: Both groups had similar rates of symptomatic disease, hospitalization, and duration of fever. Among children with asthma mean age was 10.3 years, 59.6% were male, and 84.3% had mild asthma. Dyspnea was more prevalent in asthmatic children (p:0.012), but other clinical findings were not different from those of healthy controls. 12.4% (n:11) of asthmatic children had asthma exacerbation, 2.2% (n:2) of them were hospitalized; one (1.1%) of which was due to asthma exacerbation.

Conclusion: The course of COVID-19 in patients with mild to moderate asthma, who were followed up regularly and who were compliant with their treatment, was similar to their healthy peers. Since there was no severe asthma case in our study, the results could not have been generalized to all asthmatic patients. Further comprehensive and multicenter studies are required in pediatric population.
