Article: Apresentação clínica da alergia ao leite de vaca com sintomatologia respiratória
[show abstract] [hide abstract]
ABSTRACT: Os alérgenos do leite de vaca são os primeiros antígenos a entrar em contato com a criança. A sintomatologia, em geral multissistêmica, pode estar relacionada ao trato gastrointestinal, à pele e, raramente, ao aparelho respiratório. Objetivo: Descrever algumas características clínicas e epidemiológicas de crianças com alergia ao leite de vaca com sintomas respiratórios. Casuística e método: Foram avaliadas retrospectivamente 17 crianças com acometimento do trato respiratório imediato à ingestão de leite de vaca que, com a exclusão deste tipo de alimento por quatro a seis semanas, se tornaram assintomáticas e, posteriormente, voltaram a apresentar sintomas respiratórios com a reintrodução, em ambiente hospitalar, do leite de vaca. Resultados: Não houve diferença quanto ao sexo e 14 das 17 crianças tinham antecedentes atópicos familiares. O tempo médio do aleitamento materno exclusivo foi de 2,9 meses e o do início dos sintomas, de 3,6 meses. Oito dos dez testes de hipersensibilidade cutânea imediata ao leite de vaca foram positivos. As manifestações clínicas foram: lactente chiador (nove), asma (cinco), otite de repetição (duas), deficiência seletiva de IgA associada com broncoespasmo (duas), rinoconjuntivite alérgica (uma). Conclusão: Em lactentes chiadores a alergia ao leite de vaca deve ser incluída no diagnóstico diferencial e em pacientes com antecedentes familiares atópicos deve ser estimulado o aleitamento materno exclusivo. Entretanto, o diagnóstico preciso é importante para evitar privações alimentares desnecessárias.Jornal de Pneumologia. 01/2001; -
Article: Can conjunctival provocation test facilitate the diagnosis of food allergy in children?
[show abstract] [hide abstract]
ABSTRACT: Food allergy is common in children, occurring in 5-7.5%. The diagnosis may, however, be difficult. Elevated IgE or positive skin prick test to a food allergen is often considered proof of allergy, but may represent sensitisation without clinical manifestations. For a precise diagnosis oral challenge is necessary, but this is often not performed because of risk of serious allergic reactions. The aim of this study was to evaluate whether conjunctival provocation test would facilitate the diagnosis of IgE-mediated food allergy. One hundred and forty-nine children with 174 possible diagnoses of food allergy were included. General examination, skin prick test and specific IgE were performed, as well as conjunctival provocation test of the suspected food allergen. Open food challenges and double-blind placebo controlled tests were performed in order to diagnose possible food allergy. Forty-six children with strongly positive conjunctival reactions (rubor, itching, oedema) to fifty food allergens were all proven to have allergy to the food in question. The children with negative conjunctival provocation tests showed no allergic reactions when challenged. We find that a strongly positive conjunctival reaction to a food allergen correlates well with true allergy. An oral challenge should be carefully performed. With a negative conjunctival test an oral challenge may safely be performed.Allergologia et Immunopathologia 38(6):321-6. · 1.04 Impact Factor
