ABSTRACT

Background: Dust mites play an important role as allergens all around the world, with Dermatophagoides pteronyssinus, Dermatophagoides farinae and Blomia tropicalis as the species that trigger most allergic reactions.
Objective: Identifying the sensitization to allergenic extracts of highly prevalent dust mites in children with asthma and allergic rhinitis in the city of Camagüey, Cuba, and establishing a comparison between different products of diverse origin.
Methods: The Prick Test was performed on 14 children (age 2 to 13) with allergic rhinitis and/or asthma that visited the Allergy department of Previsora Policlinic in Camagüey. Lancets Stallergens were used in these tests, containing different allergenic extracts: DIATER at 50,000 UB; ALK-Abelló at 30 HEP or BIOCEN at 20,000 UB.
Results: Most patients suffered from allergic rhinitis. The greatest sensitization to BIOCEN was found with D. siboney, whereas D. pteronyssinus was the result for DIATER and ALK-Abelló. The greatest arithmetic mean of the wheal was for Dermatophagoides siboney and Dermatophagoides farinae from BIOCEN y ALK-Abelló, respectively. The lowest arithmetic mean of the wheal was for Blomia tropicalis from BIOCEN, an extract that shows an increasingly moving tendency: BIOCEN, DIATER, ALK-Abelló.
Conclusion: The standardized allergenic extracts from BIOCEN, DIATER and ALK-Abelló showed similar levels of sensitization in children with allergic rhinitis and asthma.
