Asthma Management Guidelines

Introduction to Asthma Management

The fundamental principle of asthma management is using the lowest effective dose of medication to maintain control while minimizing side effects, as recommended by the GINA guidelines 1

Asthma diagnosis requires compatible clinical history PLUS objective confirmation of variable expiratory airflow limitation on lung function testing, according to the European Respiratory Review 4, 3
GINA recommends five methods to objectively confirm excessive variability in lung function, including positive bronchodilator responsiveness test with spirometry, excessive variability in twice-daily PEF measurements, increase in lung function after 4 weeks of ICS treatment, positive bronchial challenge test, and excessive variation in lung function between visits 4

The GINA guidelines recommend a preferred treatment track using low-dose ICS-formoterol as the reliever medication at all steps, which reduces severe exacerbations by ≥60% compared with SABA alone 2
Long-acting beta2 agonists (LABAs) should NEVER be used as monotherapy for asthma, as this increases risk of asthma-related death, as stated by the Praxis Medical Insights 2, 3

Immediate treatment for acute severe asthma includes high-dose inhaled β2-agonists, systemic corticosteroids, oxygen therapy, and add ipratropium bromide for life-threatening features, as recommended by the Praxis Medical Insights 1, 2, 5, 6
Hospital admission criteria include any life-threatening features, severe features persisting after initial treatment, and PEF <33% of predicted after treatment, according to the Praxis Medical Insights 1, 3

All patients must receive a written asthma action plan, training on proper inhaler technique, and understanding of "relievers" versus "preventers", as recommended by the Praxis Medical Insights 2, 1, 3

Children aged 6-11 years may use new treatment options added at Steps 3-4 in GINA 2021, and for inhaled steroid concerns, use the lowest dose providing acceptable control, as stated by the Praxis Medical Insights 2
Pregnant women with worsening asthma should be referred for specialist consultation, according to the Praxis Medical Insights 2

Common modifiable risk factors for exacerbations include allergen exposure, environmental tobacco smoke, air pollution, poor asthma control, medication non-adherence, poor inhaler technique, obesity, and comorbidities, as reported by the European Respiratory Review and the Praxis Medical Insights 8, 7, 3, 2

GINA now functions as an asthma strategy rather than rigid guideline, emphasizing evidence-based approach with customization for patient care, adaptation to local healthcare systems, and country-specific guidelines, as recommended by the Journal of Allergy and Clinical Immunology and the Praxis Medical Insights 7, 3, 2
Annual influenza vaccination is recommended for all patients with persistent asthma, according to the Praxis Medical Insights 3
