RESUMENEl síndrome de enterocolitis inducida por proteínas alimentarias es una alergia alimentaria no mediada por inmunoglobulina E que se manifiesta clínicamente con vómitos profusos y repetitivos, en ocasiones, asociados a diarrea, y puede llegar a asociar deshidratación y letargia, con riesgo de desarrollo de shock. A pesar de su potencial gravedad, el índice de sospecha de este síndrome es bajo, lo que demora su diagnóstico, especialmente, en aquellos casos que son desencadenados por alimentos sólidos. La presencia de vómitos y la duración de más de un minuto son los datos clave que pueden diferenciarlo de los episodios breves, resueltos e inexplicados. Se presenta el caso de una lactante de 6 meses de vida con diagnóstico final de síndrome de enterocolitis inducida por proteínas alimentarias por ingesta de kiwi. Palabras clave: kiwi, síndrome de enterocolitis inducida por proteínas alimentarias, episodios breves, resueltos e inexplicados, vómitos, hipersensibilidad.
ABSTRACTFood protein-induced enterocolitis syndrome (FPIES) is a non-IgE food allergy manifesting as profuse, repetitive vomiting, sometimes with diarrhea, leading to dehydration and lethargy that can be severe and lead to shock. Despite the potential severity, awareness of FPIES is low and diagnosis is often delayed, especially in those triggered by solid foods. Presence of vomits and duration of more than 1 minute are the key differential factors to distinguish FPIES from brief resolved unexplained events. We report a case of a 6-month-old infant finally diagnosed as having kiwi induced FPIES.
