Resumo

Objetivo: Identificar perfis metabólicos potencialmente associados à adesão ao tratamento e à gravidade da rinite alérgica em crianças e adolescentes. Métodos: Trata-se de um estudo prospectivo desenvolvido em um hospital universitário no Brasil, envolvendo 25 voluntários. Os espectros de RMN ¹H do soro dos voluntários foram obtidos e processados utilizando estatística multivariada. Inicialmente, foi empregada a Análise de Agrupamentos Hierárquicos (HCA) resultando em dois grupos, contendo onze e quatorze amostras cada. Utilizou-se a Análise Discriminante Ortogonal por Mínimos Quadrados (OPLS-DA) para identificar as variáveis responsáveis pela discriminação. Resultados: O autorrelato de adesão dos pacientes ao tratamento mostrou-se falho quando confrontados com os resultados da HCA. A principal diferença entre os grupos foi a resposta ao tratamento. No grupo II , 81,8% dos voluntários não responderam ao tratamento, enquanto no grupo I, esse número foi igual a 42,8%. Alanina, serina, arginina, colina, N-acetil D-glicosamina, glutamato, lactato, glicose, VLDL/LDL foram os metabólitos identificados. Observou-se que o perfil metabólico dos voluntários do Grupo II pode indicar uma condição clínica mais grave em comparação aos do Grupo I. Conclusão: A RMN demonstrou capacidade de identificar a resposta ao tratamento da rinite alérgica, diferenciando pacientes com formas mais graves e crônicas da doença.
