Insights
Children with atopic disorders like eczema, asthma, and allergic rhinitis face higher risks for other related conditions. Early recognition of these comorbidities is crucial for effective treatment and improved quality of life.
Area of Science:
- Pediatric Allergy and Immunology
- Primary Care Medicine
- Epidemiology
Background:
- Atopic disorders, including atopic eczema, asthma, and allergic rhinitis, are common in children.
- Comorbidities, both atopic and non-atopic, can significantly impact a child's health and quality of life.
- Understanding the spectrum of associated conditions is vital for comprehensive patient management.
Purpose of the Study:
- To investigate the range of atopic and non-atopic comorbid symptoms and diseases in children diagnosed with physician-diagnosed atopic disorders.
- To identify specific comorbidity patterns associated with atopic eczema, asthma, and allergic rhinitis in pediatric populations.
Main Methods:
- Utilized a nationwide primary care database from the Netherlands Institute for Health Services Research.
- Included children aged 0-18 years with routinely collected healthcare data from 2014.
- Employed logistic regression analysis to assess associations between atopic disorders and comorbid conditions, calculating odds ratios (ORs).
Main Results:
- Children with one atopic disorder had an increased risk of other atopic-related symptoms, irrespective of formal diagnosis.
- Atopic eczema was linked to increased risks of infectious skin diseases (OR: 1.2-3.4).
- Asthma correlated with higher occurrences of airway symptoms/diseases (OR: 2.1-10.3), and allergic rhinitis with ENT issues (OR: 1.5-3.9).
Conclusions:
- General practitioners may not always recognize the full scope of atopic and non-atopic comorbidities in children.
- Children with existing atopic disorders require targeted attention for associated conditions to prevent under-treatment.
- Proactive management of comorbidities is essential to improve health outcomes and quality of life for affected children.
Objective:
This study aimed to investigate both atopic and non-atopic comorbid symptoms and diseases in children with physician-diagnosed atopic disorders (atopic eczema, asthma and allergic rhinitis).
Methods:
All children aged 0-18 years listed in a nationwide primary care database (the Netherlands Institute for Health Services Research-Primary Care Database) with routinely collected healthcare data in 2014 were selected. Children with atopic disorders were matched on age and gender with non-atopic controls within the same general practice. A total of 404 International Classification of Primary Care codes were examined. Logistic regression analyses were performed to examine the associations between the presence of atopic disorders and (non-)atopic symptoms and diseases by calculating ORs.
Results:
Having one of the atopic disorders significantly increased the risk of having other atopic-related symptoms, even if the child was not registered as having the related atopic disorder. Regarding non-atopic comorbidity, children with atopic eczema (n=15 530) were at significantly increased risk for (infectious) skin diseases (OR: 1.2-3.4). Airway symptoms or (infectious) diseases (OR: 2.1-10.3) were observed significantly more frequently in children with asthma (n=7887). Children with allergic rhinitis (n=6835) had a significantly distinctive risk of ear-nose-throat-related symptoms and diseases (OR: 1.5-3.9). Neither age nor gender explained these increased risks.
Conclusion:
General practitioners are not always fully aware of relevant atopic and non-atopic comorbidity. In children known to have at least one atopic disorder, specific attention is required to avoid possible insufficient treatment and unnecessary loss of quality of life.

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.
