This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Background:
– The incidence of pediatric asthma exacerbations during the COVID-19 pandemic has been evaluated; however, the incidence of severe acute asthma (SAA) requiring a Pediatric Intensive Care Unit (PICU) admission is unknown. Furthermore, we examined several factors which might influence this incidence, such as environmental triggers or changes in COVID-19 lockdown regulations.Methods:
– In this single-center, retrospective cohort study running from 2018 to 2021, all PICU admissions for SAA of children above two years of age at a tertiary hospital in the Netherlands were included. Information on potential asthma triggers during the pandemic, including viral infections, concentrations of ambient fine particulate matter (PM2.5) and pollen index were evaluated.Results:
– In total, 168 children were included in this study. While we observed a decrease in PICU admissions for SAA during lockdown periods, there was an increase in the admission rates in the periods without a lockdown, with the highest peak from August to November of 2021. This peak in the fall of 2021 did not align with pollen or ambient PM2.5 concentrations (r =-0.04 for pollen and r =0.23 for PM2.5).Discussion:
– COVID-19 lockdowns influenced the admission rates for SAA at the PICU both during and after the lockdowns in the Netherlands. We hypothesize that an increase in viral infections after lockdown periods was the reason for the altered incidence of SAA at the PICU in late 2021, rather than air pollution and pollen concentrations.
