COVID-19 in Children With Severe Lung Disease-A Tertiary Center Cohort Study in Denmark.

BACKGROUND

Severe lung disease such as chronic pulmonary disease (CPD), severe asthma and cystic fibrosis (CF) in children is associated with increased risk of severe COVID-19. Information regarding SARS-CoV-2 infection, disease severity and outcome of COVID-19 is limited in this pediatric population.

OBJECTIVES

We captured the number of SARS-CoV-2 infected children and evaluated COVID-19 disease severity in non-immunized children with CPD, asthma, and CF in a cohort at a Danish tertiary center.

METHODS

The number of children with PCR-verified SARS-CoV-2 infection in the cohort and in the age-related background population was identified through the Danish Microbiology Database. Clinical data were retrieved from the electronic medical health records and from the Danish Health Authority.

RESULTS

In a cohort of 664 children with severe lung disease 594 were either PCR-tested or had an antibody test for SARS-CoV-2 infection due to symptoms or exposure and 18 (3%) had verified SARS-CoV-2 infection. The total number of verified SARS-CoV-2 infection was at that time 34.575(4.342%) thus, not significantly different from the reference population (p = 0.152). The symptoms ranged from asymptomatic to mild symptoms, and none of the children with severe lung disease required hospitalization due to COVID-19. None of the children were treated with antiviral treatment during the acute infection.

CONCLUSION

Of the 664 children in the Danish cohort with severe lung disease, none were hospitalized with COVID-19. Our findings imply that this particular group of patients do not experience increased risk of severe COVID-19.
