Insights
Many childhood asthma patients remain symptomatic long-term. Those with attacks solely during infections showed better outcomes, suggesting distinct asthma subtypes for targeted treatment.
Area of Science:
- Pediatrics
- Pulmonology
- Clinical Epidemiology
Background:
- Childhood asthma is a common chronic respiratory disease.
- Long-term prognosis and distinct clinical phenotypes in pediatric asthma require further investigation.
Purpose of the Study:
- To evaluate the long-term symptom resolution in a cohort of children with asthma.
- To identify factors influencing asthma prognosis and explore distinct clinical presentations.
Main Methods:
- A cohort of 207 children (aged 4-10 years) diagnosed with asthma was followed up 4-6 years later.
- Data collected included symptom status, attack triggers, and co-morbidities like eczema, otitis media, and history of adenoidectomy.
Main Results:
- Overall, 26% of children became symptom-free, while 74% continued to experience symptoms.
- A higher proportion of symptom-free outcomes (45%) was observed in children whose asthma attacks were exclusively linked to respiratory infections.
- Factors such as frequent attacks, co-existing eczema, and a history of otitis media or adenoidectomy were associated with a poorer prognosis.
Conclusions:
- Childhood asthma prognosis varies significantly, with a notable subgroup experiencing symptom resolution.
- Children with asthma attacks triggered solely by respiratory infections may represent a distinct clinical entity (wheezy bronchitis) with a better outlook.
- Subgrouping childhood asthma is clinically valuable for tailoring treatment intensity and management strategies.
Abstract:
A series of 207 asthmatic children aged 4-10 years studied during the years 1976-1978 were called for a follow-up study 4-6 years later. Of these, 53 (26%) children were completely symptom-free and 154 still had symptoms. The proportion of symptom-free patients was highest (45%) among those having attacks only during respiratory infections. The prognosis was worsened by such factors as a high rate of attacks, an association with eczema and a history of otitis media or adenoidectomy. The clinical picture of disease among children having attacks only during respiratory infections (wheezy bronchitis) was distinctive from that in asthma and may be separated as its own entity. Subgrouping of childhood asthma is beneficial for a clinician when considering the intensity of therapy or the need for controls.
