Insights
Preschool children with severe asthma often remain uncontrolled despite inhaled corticosteroids (ICS). This study highlights the need for better asthma management strategies in young children, focusing on severe exacerbations and symptom control.
Area of Science:
- Pediatric Pulmonology
- Asthma Research
- Clinical Trials
Background:
- Preschool children experience more severe asthma exacerbations than school-aged children.
- Limited data exists on the characteristics, hospitalizations, phenotypes, and symptoms in this young age group.
- Severe asthma exacerbations in children are defined by systemic steroid use or hospitalization.
Purpose of the Study:
- To assess baseline characteristics, hospitalizations, and symptoms in children with severe preschool asthma.
- To analyze data from the Tiotropium bromide in preventing severe asthma exacerbations (TIPP) study.
- To evaluate asthma control levels in preschool children using GINA guidelines.
Main Methods:
- Analysis of 100 children aged 1-5 years with severe preschool asthma from the TIPP study.
- Assessment of baseline characteristics including past exacerbations and the TRACK score.
- Daily symptom recording using the Pediatric Asthma Caregiver Diary (PACD) for four weeks.
Main Results:
- Children experienced a mean of 5.8 severe asthma exacerbations in the prior 24 months.
- At randomization, 58% of children were uncontrolled, 35% partially controlled, and only 7% controlled according to GINA guidelines.
- The mean TRACK score was 46.9 ± 19.0.
Conclusions:
- Most preschool children with severe asthma remain uncontrolled or partially controlled, even with inhaled corticosteroids (ICS).
- This indicates a significant unmet need for improved asthma management in this vulnerable population.
- Further research is needed to optimize treatment strategies for severe preschool asthma.
Objective:
Children with preschool asthma suffer disproportionally more often from severe asthma exacerbations with emergency visits and hospital admissions than school children. However, there are only a few reports on characteristics, hospitalization, phenotypes and symptoms in this age cohort.
Patients And Methods:
This analysis of an ongoing prospective trial of Tiotropium bromide in preventing severe asthma exacerbations (the TIPP study) assessed baseline characteristics, hospitalizations and symptoms in 100 children with severe preschool asthma. Children aged 1-5 years were analyzed at study enrollment and daily symptoms were recorded by an electronic diary [Pediatric Asthma Caregiver Diary (PACD)] for the following four weeks until randomization.
Results:
At enrollment, the total number of severe asthma exacerbations, defined as three days systemic steroid use or hospitalization in the last 24 months, was mean (±SD) 5.8 ± 5.7 and the test for respiratory and asthma control in kids (TRACK) was mean 46.9 ± 19.0. Daily recording of symptoms by the PACD revealed that only 7 patients were controlled at randomization, whereas 35 were partially and 58 were uncontrolled according to GINA.
Conclusion:
Despite protective therapy with inhaled corticosteroids (ICS), most children of this severe asthma cohort were only partially or uncontrolled according to GINA guidelines.

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.
