|January 1, 1995
Summary
Domestic mites like D. pteronyssinus and D. farinae are the primary causes of atopic diseases in Brazilian children. This study identified key inhalant and food allergens contributing to these conditions across Brazil.
Area of Science:
- Allergy and Immunology
- Pediatric Dermatology
- Environmental Health
Context:
- Atopic diseases are a growing concern in pediatric populations globally.
- Understanding regional allergen prevalence is crucial for effective management.
- Brazil's diverse environment presents unique challenges in identifying etiological agents.
Purpose:
- To identify the primary etiological agents responsible for atopic diseases in Brazilian children.
- To conduct a multicenter study across 8 distinct geographical areas in Brazil.
- To analyze results from prick tests using inhalant and food antigens.
Summary:
- Prick tests were performed on Brazilian children, with positive results defined by a wheal diameter of ≥3 mm.
- Inhalant allergens were the most common triggers, with Dermatophagoides pteronyssinus (66.6%) and Dermatophagoides farinae (66.0%) being most prevalent.
- Food allergens showed lower positive rates, with cow milk (5.2%) and peanut (3.5%) being the most frequent.
Impact:
- Identifies domestic mites as the leading cause of atopic diseases in Brazilian children.
- Provides data on specific allergen sensitization relevant to different geographical areas in Brazil.
- Informs public health strategies and clinical practice for managing pediatric atopic diseases in Brazil.
