Background: One of the most common food allergies in the pediatric population is allergy to cow's milk protein (CMPA). Treatment consists of avoiding cow's milk proteins in lactating mothers and/or using therapeutic formulas based on hydrolysates or vegetable formulas. In infants with CMPA at diagnosis, a different gut microbial profile has been found compared to healthy children, with a reduction in beneficial bacteria. The aim of this study was to evaluate changes in the gut microbiota profile and its metabolites, dietary patterns and anthropometric variables in a pediatric cohort with CMPA after six months on a restrictive diet compared to healthy controls. Methods: In total, 21 patients diagnosed with CMPA and a control group of 24 healthy infants participated in this study. The fecal microbiota of all participants were investigated by metataxonomic analysis of 16S rDNA amplicons, and fecal short-chain fatty acids were measured by gas chromatography. Epidemiological assessment and dietary questionnaires were carried out for both groups. Results: Regarding growth, no significant differences were found, but differences in dietary intake of some macro- and micronutrients were observed. Patients who were breastfed at six months had higher bifidobacteria and lipid intakes than patients fed with hydrolyzed formulas. Conclusions: Although the growth of CMPA infants fed with therapeutic formula is similar to breastfed CMPA infants, there are differences in microbiota composition and macronutrient intake that underline the importance of continued breastfeeding in CMPA cases.

- Abstract
Resumen trabajo presentado en el XII Workshop Sociedad Española de Microbiota, Probióticos y Prebióticos (SEMiPyP) y I Congreso Sociedad Iberoamericana de Microbiota, Probióticos y Prebióticos (SIAMPYP), celebrado de forma virtual del 15 al 18 de septiembre de 2021., Introducción. De las reacciones de hipersensibilidad causadas por alimentos, la alergia a la proteína de la leche de vaca (APLV) es la más común en los lactantes. En la mayoría de casos se trata de una alergia mediada por IgE, si bien las formas no mediadas son las más desconocidas y difíciles de diagnosticar, con una afectación retardada y fundamentalmente digestiva. Dentro de estas destaca por su gravedad el síndrome de enterocolitis inducida por proteínas de leche de vaca (FPIES). Objetivo. El objetivo de este estudio es buscar biomarcadores microbianos e inflamatorios en heces asociados con distintas formas de presentación de APLV que pudieran facilitar el diagnóstico de estas patologías en la infancia. Metodología. Se parte de un grupo de pacientes = 1 año con distintas formas de presentación de APLV reclutados a lo largo de un año en tres Hospitales de Asturias. Con fines comparativos, se recluta en centros de atención primaria un grupo control de lactantes sanos sin ninguna enfermedad digestiva ni alérgica. A partir de las heces de los niños se realiza el análisis de parámetros inflamatorios, así como de la composición microbiana y de sus metabolitos. Resultados. Se detectaron distintos perfiles entre el grupo control y los pacientes en función del tipo de hipersensibilidad. Destaca la disminución de la excreción fecal de ácidos grasos de cadena corta (AGCC) en aquellos niños con formas no mediadas por IgE respecto al grupo de niños sanos y a los pacientes con APLV mediada por IgE. Conclusiones. Las poblaciones microbianas que se desarrollan en el intestino del lactante y la producción de metabolitos bacterianos específicos pueden ser claves en la interacción con el sistema inmunitario del lactante en este tipo de alergias. El análisis de muestras de heces podría ayudar al diagnóstico, sobre todo en los casos no mediados por IgE.

Trabajo presentado en el 6th International Conference on Food Digestion, celebrado en Granada (España), del 2 al 4 de abril de 2019, [Introduction] Milk is a complex food with 3.3% protein content and is fundamental in the diet throughout the all life and especially during childhood. However, cow`s milk protein allergy (CMPA) is very common in infancy and the only therapeutic option is a dairy elimination diet. The impact of the absence of milk proteins and dairy products in the gut ecosystem development of the infant has rarely been assessed. [Objective] To evaluate the intestinal changes in infants with non-IgE mediated CMPA after successful standardized oral challenges (SOCs) and introduction of milk in their diet. [Methodology] Twelve allergic children (between 1 and 2 years old) that were initially on a milk restriction diet provided stool samples before SOCs, and a week and a month after introduction of milk. Changes in the intestinal microbiota populations were determined by high-throughput sequencing of the 16S rRNA gene, meanwhile diverse microbial metabolites (short chain fatty acids and indoles) were quantified by chromatographic methods. [Main findings] The introduction of milk in infants that developed tolerance acquisition increased significantly the levels of fecal lactic acid bacteria. Microbial metabolites derived from the fermentation of proteins, such as branched chain fatty acids and p-cresol diminished. Statistical differences were observed between infants that were consuming probiotics (Lactobacillus rhamnosus GG) during the restriction diet period and those that were not. [Conclusion] The introduction of dairy products in the diet is accompanied by modifications in the infant gut environment through changes in the microbiota and protein metabolic end-products. Consumption of probiotics may affect the response to SOC with milk.

- Abstract
Trabajo presentado en 52nd Annual Meeting of the European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN), celebrado en Glasgow (Escocia), del 5 al 8 de junio de 2019, [Objectives and Study] Cow's milk protein allergy (CMPA) is very common in infancy. Elimination diet is currently, the only therapeutic option available. Standardized oral milk challenges (SOC) are performed to determine tolerance development. The aim of our study was to analyze changes in feces of infants with non-IgE mediated CMPA after successful milk challenges (tolerance development) regarding microbiota composition and metabolic and cytokine profile [Methods]: Twelve non-IgE mediated CMPA children consuming extensively hydrolyzed formulas for at least 6 months ( 4 consumed formulas supplemented with Lactobacillus rhamnosus GG (LGG) ). In all cases a SOC was scheduled in order to determine tolerance acquisition. All 12 infants provided three consecutive stool samples: one before performing the SOC, one after a week and one after a month. Gut microbiota was determined through high-throughput sequencing. Microbial derived metabolites were analyzed by chromatographic methods. Fecal cytokines related to Th1/Th2 balance were also determined. [Results] With the re-introduction of milk, lactic-acid bacteria, in particular the genus Lactococcus, increased significantly. The content of some microbial metabolites, such as escatol, increased, meanwhile branched chain fatty acids diminished. After SOC, differences in TNF-a and butyrate levels were observed between infants consuming consume LGG supplemented formulas and those without probiotic supplementation. [Conclusions] These findings indicate that introduction of dairy products is followed by modifications in infant´s gut environment through maturation of the microbiota and its metabolic products. Consumption of probiotics may tune these profiles.

Trabajo presentado en el 10th Workshop on Probiotics and Prebiotics, de la Sociedad Española de Probióticos y Prebióticos (SEPyP), celebrado en Las Palmas de Gran Canarias, del 6 al 8 de febrero de 2019, [Background] Cow’s milk protein allergy (CMPA) is very common in infancy. Currently, the only therapeutic option is a dairy elimination diet. Standardized oral milk challenges are performed each 6 months to determine possible tolerance adquistion. [Aim] To analyze the intestinal changes in feces of infants with non-IgE mediated CMPA after successful milk challenges and introduction of dairy product in their diet. [Methods] Twelve allergic children (between 1 and 2 years old) that were initially consuming extensively hydrolyzed formulas provided stool samples before oral milk challenges, and a week and a month after. Changes in the intestinal microbiota populations were determined by high-throughput sequencing of the 16S rRNA gene, meanwhile diverse microbial metabolites (short chain fatty acids and indoles) were quantified by chromatographic methods. [Results] The introduction of milk in infants with outgrowing non-IgE CMPA increased significantly the levels of fecal lactic acid bacteria, in particular the genus Lactococcus. Microbial metabolites derived from the catabolism of proteins, such as escatol (produced from tryptophan) enhanced, meanwhile branched chain fatty acids diminished. [Conclusions]: The introduction of dairy products is accompanied by modifications in the infant gut environment through changes in the microbiota and protein metabolic end-products according to this kind of dietary change.

- Abstract
Trabajo presentado en el VIII Workshop de la Sociedad Española de Probióticos y Prebióticos (SEPyP), celebrado en Santiago de Compostela (España) el 23 y 24 de febrero de 2017, [Objetivos] La Alergia a Proteína a Leche de Vaca (APLV) es relativamente frecuente en niños pequeños. En las formas no mediadas por IgE, el diagnostico se basa en la historia clínica y una prueba de provocación positiva, siendo el tratamiento una dieta de exclusión. Una gran parte de los niños va a adquirir tolerancia antes de los 3 años, es por ello que, a partir del año, se valora la pauta de reintroducción de leche mediante pruebas de tolerancia. El objetivo de este trabajo fue analizar los cambios en la microbiota intestinal y parámetros asociados en heces de niños con APLV no mediada por IgE tras las pruebas de tolerancia a PLV. [Metodología] Se reclutó un grupo de niños entre 1 y 2 años y se recogieron muestras de heces antes de la prueba de tolerancia, a la semana y al mes de realización de la misma. Se estudió la microbiota intestinal mediante análisis metataxonómico del ADNr 16S, así como diversos marcadores inmunológicos y de inflamación, incluyendo la microbiota recubierta por IgA e IgG mediante citometría de flujo, la calprotectina fecal mediante ELISA y diversas citoquinas relacionadas con el balance Th1/Th2 mediante el sistema Bio-Plex. [Resultados] Tras la realización de las pruebas la mayoría de los niños superaron la tolerancia y solo en uno de los casos la provocación resultó positiva. El patrón de colonización microbiana en el niño en el que persiste la sensibilidad a PLV, a diferencia del resto, presentó una marcada presencia de los filos Verrucomicrobia y Proteobacteria. Se observó un aumento de los niveles de calprotectina, así como el grado de opsonización de la microbiota, a la semana de la introducción de la leche. [Conclusiones] En consonancia con la sintomatología gastrointestinal preponderante en estas formas de APLV, los resultados obtenidos apuntan a una respuesta intestinal predominantemente inflamatoria de distinto grado.
