Abstract
Introduction: Severe asthma affects approximately 4%-5% of asthmatic patients and increases susceptibility to respiratory infections, including SARS-CoV-2. The impact of COVID-19 on severe asthma remains unclear. We aimed to evaluate the effects of SARS-CoV-2 infection on asthma control, quality of life, and lung function.
Methods: A retrospective study of 114 severe asthma patients followed in our severe asthma unit from March 2020 to July 2022. We compared pre- and post-COVID-19 scores of the Asthma Control Test (ACT), Control of Allergic Rhinitis and Asthma Test (CARAT), Mini Asthma Quality of Life Questionnaire (mini-AQLQ) and lung function. Statistical analysis was performed using SPSS 25 (p <0.05).
Results: Among 49 infected patients, ACT scores significantly decreased (p = 0.002). CARAT, mini-AQLQ, and lung function showed no significant differences.
Conclusion: SARS-CoV-2 infection negatively impacted asthma control, with a significant decrease in ACT scores. Further studies are needed to clarify long-term effects.
