Insights
Asthma hospitalizations in children remain stable, with 10% hospitalized annually. Recognizing severe asthma signs and implementing action plans are crucial for prevention and prompt treatment.
Area of Science:
- Pediatric Pulmonology
- Allergy and Immunology
Context:
- Despite decreased asthma mortality, childhood asthma hospitalizations remain a significant concern.
- Approximately 10% of children with asthma experience hospitalization annually or before age ten.
Purpose:
- To identify factors associated with severe asthma attacks in children.
- To highlight effective prevention and management strategies for pediatric asthma exacerbations.
Summary:
- Factors linked to severe asthma attacks include poor lung function, bronchial hyperreactivity, uncontrolled asthma, food allergies, diminished awareness of airway obstruction, illness denial, and psychosocial challenges.
- Effective management involves tailored treatments like inhaled corticosteroids, regular follow-ups with lung function testing, and patient/caregiver education on recognizing and managing severe exacerbations.
- Prompt treatment, action plans, and accessible emergency care are essential for severe asthma events.
Impact:
- Improved recognition of severe asthma triggers and risk factors.
- Enhanced patient quality of life and therapeutic adherence through educational programs.
- Potential reduction in childhood asthma hospitalizations through proactive management and timely intervention.
Abstract:
Mortality by asthma has decreased, but the number of children being hospitalized is stable: 10% of the asthmatic children are hospitalized within the year, or will be at least once before their tenth year. Some factors are associated with occurrence of a severe asthma attack: poor lung function, bronchial hyperreactivity or poor asthma control, a food allergy, a decreased perception of airway obstruction prior hospitalisation, denial of illness, psychological and social difficulties. The prevention of most asthma exacerbations is possible. The treatment must be adapted to severity of asthma: inhaled steroids, even low doses, have been proven efficient. The follow-up must be regular: planned consultations, repeated lung function testing. Educational programs show an increased quality of life, therapeutic adherence or reduction of hospitalization. The patient and care giver must be able to recognize the signs of severity of asthma exacerbation; an exacerbation is considered severe if it begins suddenly, if its progression or symptoms are unusual, and therefore requires a prompt adapted treatment. An action plan and accessible emergency care are essential.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
