Better COVID-19 Outcomes in Children with Good Asthma Control

Abstract

Factors associated with COVID-19 presentation in children with asthma are poorly defined. Our study aimed to assess the clinical course of COVID-19 in children with asthma, with particular attention to possible risk factors for severe disease and long-term sequelae in this group of patients. We assessed the occurrence of SARS-CoV-2 infection in children with asthma six months before their regular outpatient visit to the asthma clinic. Characteristics of patients presenting with signs of SARS-CoV-2 upper (URTI) or lower respiratory tract infection (LRTI) were compared. We focused on factors previously associated with COVID-19 severity. Twenty-seven percent of patients (57/210) reported exposure to SARS-CoV-2 infection. In the symptomatic group, 36% (15/42) reported symptoms of LRTI and 64% (27/42) of URTI. Poorer asthma control was observed in patients with LRTI compared to URTI (80% vs. 7%, p p = 0.026). We found no PFT deterioration post-COVID-19 in either group of patients. Our results suggest good asthma control and treatment adherence prior to infection are associated with better COVID-19 outcomes in children with asthma.
