Minimum number and types of allergens for a skin prick test panel in Thai children with allergic respiratory diseases

BACKGROUND: Patterns of aeroallergen sensitization vary by countries. Testing with the minimum number of allergens is important to identify sensitized patients for a cost-effective approach. We aimed to assess the minimal skin prick test (SPT) panel to identify sensitized children with allergic resp...

Sumario:BACKGROUND: Patterns of aeroallergen sensitization vary by countries. Testing with the minimum number of allergens is important to identify sensitized patients for a cost-effective approach. We aimed to assess the minimal skin prick test (SPT) panel to identify sensitized children with allergic respiratory diseases. METHODS: The SPT results from January 2020 to December 2021 in children aged 2–18 years with symptoms of asthma or allergic rhinitis or both were retrospectively reviewed. All children received 11 allergen extracts (Dermatophagoides pteronyssinus [Der p], Dermatophagoides farinae [Der f], American cockroach, German cockroach, cat, dog, Bermuda grass, careless weed, Timothy, Acacia, and molds). The conditional approach was used to determine the allergen selection for the SPT panel. RESULTS: A total of 688 children were enrolled (mean age = 8.14 ± 3.91 years). The sensitization results were Der p (57.85%), Der f (55.09%), German cockroach (18.02%), American cockroach (17.01%), cat (11.77%), Acacia (3.49%), Bermuda grass (3.34%), molds (3.05%), Timothy (2.33%), dog (1.89%), and careless weed (1.60%). Der p, Der f, and German cockroach were required to detect at least 95% of sensitized children. If the SPT panel added Acacia, cat, American cockroach, Bermuda grass, and careless weed, sensitization was detected in 99–100% of cases. CONCLUSIONS: Indoor allergens (Der p, cockroach, and cat) were common causes of sensitization in Thai children with allergic respiratory diseases. Eight allergens were sufficient for sensitization identification in Thai children with asthma or allergic rhinitis or both in clinical practice.
