Resumo: | OBJECTIVE: To determine the frequency of sensitization to inhalant and food allergens in children seen at Brazilian allergy services. PATIENTS AND METHODS: Total and specific IgE serum levels to inhalant and food allergens (RAST, UniCAP® - Pharmacia) were measured in 457 children accompanied in pediatric allergy services and in 62 control children age matched. RAST equal or higher than class 1 was considered as positive (R+). RESULTS: Frequency of R+ was significantly higher among atopics (361/457, 79%) when compared to controls (16/62, 25.8%). There were no differences according to gender. The frequency of R+ to all allergens evaluated were higher among atopics when compared to controls. Significantly higher total IgE serum levels were observed among the atopics with R+ in comparison to those with R-. The frequency of R+ to main inhalant allergens were: D. pteronyssinus = 66.7% x 14.5% (p < 0.05), D. farinae = 64.5% x 17.8% (p < 0.05), B. tropicalis = 55.2% x 19.4% (p < 0.05), cockroach = 32.8% x 9.7% (p < 0.05), and cat = 12% x 8.1%. In relation to food allergens we observed: fish = 29.5% x 11.3% (p < 0.05), egg = 24.4% x 4.8% (p < 0.05), cow's milk = 23.1% x 3.2% (p < 0.05), wheat = 20% x 8.1% (p < 0.05), peanuts = 14% x 4.8% (p < 0.05), soy = 11.8% x 4.8% (p < 0.05), and corn = 10.6% x 4.8% (p < 0.05). With respect of age, food allergen sensitization predominates in young children whereas the inverse occurs with inhalant allergens. CONCLUSIONS: There was a predominant frequency of sensitization to inhalant allergens, mainly house dust mites in the evaluated patients. Food allergens were also responsible for a significant proportion of sensitization, mainly in infants. |

PACIENTES E MÉTODOS: IgE sérica total e específica (RAST) a alérgenos inalantes e alimentares (UniCAP® - Pharmacia) foram determinados em 457 crianças acompanhadas em serviços de alergia pediátrica e em um grupo de controles (n = 62). Resultados classe igual ou maior que 1 foram considerados positivos (R+). RESULTADOS: A freqüência de R+ foi significantemente maior entre os atópicos (361/457, 79%) quando comparados aos controles (16/62, 25,8%). Não houve diferenças quanto ao sexo. A prevalência de R+ entre os atópicos foi significantemente maior para todos os alérgenos avaliados. Os níveis séricos de IgE total foram significantemente mais elevados entre os atópicos com R+ quando comparados aos com R-. Comparando-se atópicos e controles, a freqüência de R+ para os principais alérgenos inalantes foi como segue: D. pteronyssinus = 66,7 versus 14,5% (p < 0,05), D. farinae = 64,5 versus 17,8% (p < 0,05), B. tropicalis = 55,2 versus 19,4% (p < 0,05), barata = 32,8 versus 9,7% (p < 0,05) e gato = 12 versus 8,1%. Com os alimentos, observou-se: peixe = 29,5 versus 11,3% (p < 0,05), ovo = 24,4 versus 4,8% (p < 0,05), leite de vaca = 23,1 versus 3,2% (p < 0,05), trigo = 20 versus 8,1% (p < 0,05), amendoim = 14 versus 4,8% (p < 0,05), soja = 11,8 versus 4,8% (p < 0,05) e milho = 10,6 versus 4,8% (p < 0,05). Segundo a idade, os R+ aos alimentares predominaram entre as crianças mais jovens, e o inverso ocorreu com os inalantes. CONCLUSÕES: Nesta população, predominou a sensibilização aos aeroalérgenos, sobretudo aos ácaros domiciliares, e os alimentos foram importantes em crianças mais jovens.Universidade Federal de São Paulo (UNIFESP) Departamento de Pediatria Disciplina de Alergia e Imunologia Clínica e ReumatologiaUniversidade Federal de São Paulo (UNIFESP)Grupo PROALUNIFESP, Depto. de Pediatria Disciplina de Alergia e Imunologia Clínica e ReumatologiaUNIFESPSciELOSociedade Brasileira de PediatriaUniversidade Federal de São Paulo (UNIFESP)Grupo PROALNaspitz, Charles Kirov [UNIFESP]Solé, Dirceu [UNIFESP]Jacob, Cristina Miuki Abe [UNIFESP]Sarinho, Emanuel [UNIFESP]Soares, Francisco J.
