SOARES, Fernanda Aparecida Almeida et al. Indoor allergen sensitization profile in allergic patients of the allergy clinic in the University Hospital in Uberlândia, Brazil. Rev. Assoc. Med. Bras. [online]. 2007, vol.53, n.1, pp.25-28. ISSN 1806-9282.

OBJECTIVE: To evaluate allergens among patients with allergic respiratory disease attended at the Allergy Clinic of the University Hospital - Federal University of Uberlândia. METHODS: A retrospective study was performed using medical records. Patients were included if their ISAAC questionnaires were correctly filled out and their skin prick tests were positive to at least one of the allergens from Dermatophagoides pteronyssinus (Der p), Dermatophagoides farinae (Der f), Blomia tropicalis (Blo t), Canis familiaris (Can f), Felis domesticus (Fel d), Blattella germanica (Bla g) and Alternaria alternata. RESULTS: Two-hundred and twelve medical records fulfilled the inclusion criteria. Allergic rhinitis was the main clinical diagnosis (32%), followed by concomitant manifestation of asthma and rhinitis (29.7%), and asthma, rhinitis and atopic dermatitis (9.4%). Asthma alone was found only in 1.9% of patients. The total sensitization observed was 73.5%, of which 61.7%, 59.9%, 54.7%, 45.7%, 38.2%, 33.3%, 9.9% were sensitized to Der p, Der f, Blo t, Bla g, Can f, Fel d and Alternaria, respectively. No significant difference was found between allergic disease types and source of allergen sensitization. CONCLUSION: The highest sensitization in allergic patients under study was to dust mites, especially Der p and Der f. It is noteworthy that the number of patients sensitized to cockroach extract was uncommonly high when compared to previous studies.
