What is the treatment regimen for a 12-year-old patient with persistent severe asthma?

For a 12-year-old patient with persistent severe asthma, the treatment regimen that involves high-dose inhaled corticosteroids (ICS), long-acting beta-agonists (LABA), and oral corticosteroids is appropriate due to the severity and persistence of their condition. This combination effectively addresses the underlying inflammation in the airways, helps with bronchodilation, and manages acute exacerbations.

High-dose ICS reduces airway inflammation, which is crucial for severe asthma management. The addition of a LABA provides extended bronchodilation, improving overall lung function and reducing symptoms. In cases of severe asthma, using oral corticosteroids can be necessary to control inflammation and prevent exacerbations, particularly when other medications are insufficient. This comprehensive approach ensures better asthma control, symptom relief, and a reduction in the frequency of exacerbations, which is essential for maintaining the patient's quality of life and preventing serious complications associated with severe asthma.
