Resumen
Objetivo: Analizar la modulación de la microbiota intestinal y su impacto en los síntomas del Trastorno del Espectro Autista. Métodos: Se trata de una revisión integrativa realizada en portugués en las bases de datos Pubmed, Scopus y BVS. Se utilizaron los siguientes criterios para la inclusión de artículos: artículos en inglés y español publicados entre 2020 y 2025, que abordaran la modulación de la microbiota en personas con TEA. Los criterios de exclusión fueron revisiones sistemáticas, metaanálisis, artículos de opinión, tesis doctorales y disertaciones. Resultados: De los estudios seleccionados, la intervención con prebióticos, probióticos, simbióticos y/o trasplante de microbiota fecal en personas con TEA resultó en cambios en la microbiota intestinal, en el patrón de comportamiento y mejoría en los síntomas gastrointestinales. Consideraciones finales: Se puede considerar que las alteraciones en la microbiota intestinal se observan con frecuencia en individuos con Trastorno del Espectro Autista y a menudo están relacionadas con síntomas gastrointestinales y conductuales. Las intervenciones con probióticos, prebióticos, simbióticos y trasplante de microbiota fecal surgen como estrategias prometedoras.
