Severity of COVID-19 in hospitalized patients with and without atopic disease

Abstract

Background: Data from the 2009 influenza pandemic suggested asthma might protect from severe disease in hospitalized patients. Asthma does not appear to increase risk for hospitalization or mortality with COVID-19. Objective: This study was undertaken to see if atopy actually protected those hospitalized with COVID-19. Methods: Retrospective chart review on all patients testing positive for SARS-CoV-2 over 2 months at a major adult and pediatric tertiary referral center hospital. Charts were evaluated for history of atopic disease, as were the need for ICU admission, requirement for supplemental oxygen and/or intubation, and in hospital mortality. Results: No significant differences in outcomes for patients (n = 275) based on atopic disease were noted: ICU admission, 43% versus 44.7% (atopic versus no atopic disease, respectively; p = 0.84); supplemental oxygen use, 79.1% versus 73.6% (p = 0.36); intubation rate, 35.8% versus 36.5% (p = 0.92); and mortality rate, 13.4% versus 20.7% (p = 0.19). More patients with atopic disease had COPD listed as a diagnosis in their chart (38.8% versus 17.3%, p 0.2). Conclusion: Severity of COVID-19 in hospitalized patients does not differ based on atopic status. However, adjusting for presence of COPD led to a suggestion of possible reduced severity in patients with atopy but not asthma.
