RESUMO
En los últimos años, las evidencias han demostrado la importancia de la microbiota intestinal en la salud del individuo. La dinámica de la colonización temprana y el establecimiento de una comunidad abundante y diversa de microorganismos saludables, a partir de un parto vaginal y lactancia materna, resultan fundamentales en la conformación de una matriz inmunológica saludable. Esta revisión tiene como objetivo describir las evidencias disponibles sobre el desarrollo de la microbiota en el primer año de vida y el actual potencial que ofrece el uso de prebióticos, probióticos, simbióticos y posbióticos durante esta etapa esencial de la vida
In recent years, the evidence has demonstrated the relevance of the gut microbiota in an individual's health. The dynamics of an early colonization and the establishment of a community of plenty, diverse, and healthy microorganisms from a vaginal delivery and breastfeeding are critical for the development of a healthy immune matrix. The objective of this review is to describe the available evidence on microbiota development in the first year of life and the current possibilities offered by prebiotics, probiotics, symbiotics, and postbiotics during such critical stage of life.

OBJECTIVES: The aim of the study was to determine whether esophageal baseline impedance (BI) values in children could be predictive of esophagitis. MATERIALS AND METHODS: Multichannel intraluminal impedance (MII) tracings of children 3 to 17 years of age suspected of having gastroesophageal reflux and esophagitis, who had also undergone upper endoscopy with multiple esophageal biopsies, were reviewed. Patients with eosinophilic esophagitis were excluded. Esophagitis was assessed by macroscopic and microscopic parameters. Esophageal histology was reported by 2 blinded independent pathologists unaware of the MII results. Mean BI was automatically calculated in the different MII channels (ch) by the specific software without removing any episode of increased/decreased BI. BI results were plotted against macroscopic and histological scores for each channel. RESULTS: Tracings of 87 children, 53 boys, were evaluated. Mean age was 7.4 years: 45 had histologic esophagitis, 8 macroscopic. Histologic mild esophagitis (grade 1) was observed in 30, and 15 had moderate to severe esophagitis (grade 2-3). Ten had grade 3 esophagitis. Eight had macroscopic esophagitis as well. RESULTS: in channel 6 of the MII, all 10 patients with grade 3 esophagitis and the 8 with macroscopic esophagitis had a BI <900 Ω/s (positive predictive value 100% and negative predictive value 100%), whereas none of those having a biopsy score of 0 to 2 or no endoscopic evidence of esophagitis had a mean BI below 2000 Ω/s. CONCLUSIONS: The evaluation of the BI measured in channel 6 gave us 100% prediction of grade 3 and macroscopic esophagitis. BI on channel 6 may be useful to predict severe esophageal mucosa inflammation and could potentially be used for follow-up evaluation, rather than repeating an upper endoscopy. In addition, it would seem that grade 3 esophagitis even in the absence of macroscopic esophagitis affects the integrity of the esophageal epithelium.

Objetivo: Evaluar las características epidemiológicas de un grupo de pacientes pediátricos con esofagitis eosinofílica (EEo) y las modalidades de tratamiento empleadas en Latinoamérica. Pacientes y métodos: Estudio multicéntrico, observacional, transversal. Se aplicó una encuesta a 36 Centros de Gastroenterología y Endoscopia Pediátrica de 10 países latinoamericanos con la finalidad de obtener información socio-demográfica y datos sobre el tratamiento utilizado para el manejo de los casos evaluados durante el periodo 2014-2016. Resultados: 372 casos de EEo pediátrica fueron evaluados durante el periodo 2014-2016 y 108 casos (29%) correspondieron al trimestre Abril-Junio 2016. 46,72% de los casos pertenecían al grupo de edad escolar y 71,8% consultaron por disfagia. 87,2% de los pacientes fueron manejados con dieta, 55,3% esteroides deglutidos (12,8% en monoterapia) y 6% recibió montelukast. No hubo reporte de pacientes en terapia con agentes biológicos. Conclusiones: los resultados sugieren un predominio del sexo masculino con una mayor incidencia de la enfermedad en la edad escolar y la adolescencia. Las manifestaciones clínicas más frecuentes son disfagia, vómitos y síntomas de reflujo gastroesofágico. El tratamiento más indicado por los especialistas en América Latina es la dieta seguido del uso de esteroides deglutidos. Los IBP también son ampliamente utilizados como terapia coadyuvante. Un estudio de prevalencia a nivel continental es necesario para evaluar el comportamiento de la enfermedad en diferentes regiones de América Latina.
Aims: To evaluate epidemiological features of pediatric patients with eosinophilic esophagitis in Latinamerica and therapeutical options indicated by pediatric gastroenterologists in our continent. Patients and methods: multicenter, observational, transversal study. 36 Centers of Pediatric Gastroenterology and Endoscopy from 10 latinamerican countries participated giving clinical and sociodemographic information about pediatric patients with EoE diagnosed and treated during the last two years (study period). Results: 372 cases of pediatric EoE were evaluated during period 2014-2016 (108 cases were evaluated during trimester April-June 2016). 46,72% of cases were school age children, with dysphagia been the main clinical symptom in 71,8% of patients. 87,2% of patients received diet as a main indication of treatment, 55,3% received swallowed steroids (12,8% as monotherapy) and 6% were treated with montelukast among others. There were no reports of patients under treatment with biological drugs. Conclusions: epidemiological features of our study group suggest a higher prevalence of pediatric EoE in male school age children and adolescents. Most frecuent clinical symptoms are dysphagia, vomiting and gastroesophageal reflux symptoms. Treatment is based mainly on diet and swallowed steroids. A continental prevalence study is necessary to evaluate the behavior of the disease in different regions of Latinamerica.
RESUMO
During the last twenty years Eosinophilic Esophagitis has become one the most important causes of esophageal disfunction in children, food impactation in adolescents and young adults, therapeutic failure in patients with gastroesophageal reflux disease (GERD) and the most frecuent eosinophilic disease of the gastrointestinal tract. We present recommendations for the diagnosis and treatment of the disease based in a systematic review of the literature.
