RESUMO
INTRODUCTION: There are no studies on efficacy of tofacitinib for moderate-severe ulcerative colitis (UC) in pediatric patients in Latin America. The aim of this study was to describe the efficacy and safety, in real world, treated with tofacitinib in our setting. MATERIALS AND METHODS: Case series of pediatric patients with UC who received treatment with tofacitinib in induction phase for 8 weeks and then maintenance therapy between November 2021 and February 2023. RESULTS: Four female patients, median age 14.5 (SD 2.1; RIQ 12.5-16.5) years, all with prior biologic exposure, all 4 with prior use of anti-TNF, and 2/4 with prior use of anti-integrin. Clinical, biochemical and endoscopic remission was obtained in 3/4 at induction. Information was obtained from 3 patients in 6-month maintenance, 2/3 remained in clinical, biochemical and endoscopic remission and 1/3 has not achieved biochemical or endoscopic remission. Information was obtained from 1 patient in 12-month maintenance, achieving clinical and biochemical remission, however, endoscopic remission has not been achieved. One patient was initiated for severe acute UC with risk of colectomy, with significant improvement after 7 days, reaching therapeutic objectives at induction. No serious adverse events were reported in any of the cases. CONCLUSIONS: Efficacy and safety are demonstrated with tofacitinib in pediatric patients. With high percentage of response in induction treatment, sustained over time, and safe. In the context of severe acute hospitalized UC, it has a role as a potential rescue therapy due to its rapid action.
RESUMO
INTRODUCTION: The latest joint H. pylori NASPGHAN and ESPGHAN clinical guidelines published in 2016, contain 20 statements that have been questioned in practice regarding their applicability in Latin America (LA); in particular in relation to gastric cancer prevention. METHODS: We conduc ted a critical analysis of the literature, with special emphasis on LA data and established the level of evidence and level of recommendation of the most controversial claims in the Joint Guidelines. Two rounds of voting were conducted according to the Delphi consensus technique and a Likert scale (from 0 to 4) was used to establish the "degree of agreement" among a panel of SLAGHNP ex perts. RESULTS: There are few studies regarding diagnosis, treatment effectiveness and susceptibility to antibiotics of H. pylori in pediatric patients of LA. Based on these studies, extrapolations from adult studies, and the clinical experience of the participating expert panel, the following recom mendations are made. We recommend taking biopsies for rapid urease and histology testing (and samples for culture or molecular techniques, when available) during upper endoscopy only if in case of confirmed H. pylori infection, eradication treatment will be indicated. We recommend that selected regional centers conduct antimicrobial sensitivity/resistance studies for H. pylori and thus act as reference centers for all LA. In case of failure to eradicate H. pylori with first-line treatment, we recommend empirical treatment with quadruple therapy with proton pump inhibitor, amoxi cillin, metronidazole, and bismuth for 14 days. In case of eradication failure with the second line scheme, it is recommended to indicate an individualized treatment considering the age of the pa tient, the previously indicated scheme and the antibiotic sensitivity of the strain, which implies performing a new endoscopy with sample extraction for culture and antibiogram or molecular resistance study. In symptomatic children referred to endoscopy who have a history of first or se cond degree family members with gastric cancer, it is recommended to consider the search for H. pylori by direct technique during endoscopy (and eradicate it when detected). CONCLUSIONS: The evidence supports most of the general concepts of the NASPGHAN/ESPGHAN 2016 Guidelines, but it is necessary to adapt them to the reality of LA, with emphasis on the development of regional centers for the study of antibiotic sensitivity and to improve the correct selection of the eradication treatment. In symptomatic children with a family history of first or second degree gastric cancer, the search for and eradication of H. pylori should be considered.

BACKGROUND: The effectiveness of Helicobacter pylori first-line treatment has decreased drastically with the rise of strains resistant to clarithromycin. Therapy failure has also been described in patients with infections by strains with dissimilar antimicrobial susceptibilities. The present study aims to estimate the prevalence of resistance and heteroresistance to clarithromycin in H. pylori isolates from antrum and corpus of Colombian patients. METHODS: The study material included 126 isolates from antrum and corpus biopsies from 63 symptomatic patients over 18 years old who had a gastric endoscopy performed on them between June 2014 to August 2016. PCR amplification and sequencing of the H. pylori 23S rDNA gene was performed to determine the presence of mutations associated with clarithromycin resistance. Random amplified polymorphic DNA analysis was implemented in cases of resistance and heteroresistance. RESULTS: The overall frequency of resistance to clarithromycin was 38.1% (24/63 patients), of which 19 patients had resistant isolates in both stomach segments (14 with A2143G mutation and 5 with A2142G mutation), and 5 patients had a heteroresistant status. The remaining 61.9% (39/63 patients) presented only susceptible isolates. DNA fingerprinting analysis showed different patterns in 4/22 paired isolates. CONCLUSIONS: The high prevalence of H. pylori clarithromycin-resistance obtained (> 15%) constitutes an alert for gastroenterologists and suggests the need for reconsideration of the current eradication regimen for H. pylori in the studied population. The data show that heteroresistance status is an additional factor to be considered in the assessment of resistance. In consequence, it is advisable to examine at least two biopsies from different gastric segments.

Obesity is an epidemic with important health repercussions in addition to high treatment-related costs. Between 2006 and 2007 the WHO developed new assessment tools, which aren't being globally used. In fact, there is no unified problem management across the hemisphere. Objectives: To update obesity epidemiology, to promote application of WHO's standards, to review new findings on physiopathology (i.e., fatty tissue as endocrine organ, intestinal microbiota), to update epidemiological information, and to provide management guidelines that can be integrated in clinical care. Methods: LAPSGHAN called up its members to collaborate in preparing this review article under the direction of an editor/coordinator, who selected the contents and literature with the best evidencetogether with the members. Each member prepared a separate document for each content. The chosen contents were later collated, unified, and edited. Results. This documents highlights the following: 1) Although extreme obesity is increasing in the US, overweight and obesity prevalence has stabilized, while in other countries it is alarmingly increasing; 2) New information regarding role of fatty tissue as endocrine organ and self-regulator of obesity; 3) The promising role of microbiota; and 4) Guidelines for children handling during consultation and follow-up. Conclusions: There is no widespread implementation of standards and guidelines from the World Health Organization (WHO). There is no agreement as to whether z-scores or percentiles should be used, especially regarding children under 2 due to their changing body complexion. The most accepted tool to assess overweight, obesity and severe obesity is the Body Mass Index (BMI). This document provides recommendations on how to approach clinical care with affected children.

Introduction: Pediatric ulcerative colitis (CUP), pediatric Crohn's disease (PCD), and pediatric inflammatory bowel disease not classifiable (PIDNCID) have clinical and psychosocial particularities that differentiate them from those of adults and may condition different therapeutic approaches due to possible nutritional, growth and developmental repercussions, representing a challenge for the pediatrician and gastroenterologist. Objective: Develop expert consensus evidence-based recommendations for the timely and safe diagnosis and treatment of Pediatric Inflammatory Bowel Disease (PID) in children under 18 years of age for professionals caring for these patients and healthcare payers. Methodology: Through a panel of experts from the Colombian College of Pediatric Gastroenterology, Hepatology and Nutrition (COLGAHNP) and a multidisciplinary group, 35 questions were asked regarding the clinical picture, diagnosis, and treatment of PID. Through a critical review and analysis of the literature with particular emphasis on the main clinical practice guidelines (CPGs), randomized clinical trials (RCTs), and meta-analyses of the last ten years, from which the experts made 77 recommendations that responded to each of the research questions with their respective practical points. Subsequently, each of the statements was voted on within the developer group, including the statements that achieved > 80%. Results: All statements scored > 80%. PID has greater extension, severity, and evolution towards stenosis, perianal disease, extraintestinal manifestations, and growth retardation compared to adult patients, so its management should be performed by multidisciplinary groups led by pediatric gastroenterologists and prepare them for a transition to adulthood. Porto's criteria allow a practical classification of PID. In CPE, we should use the Paris classification and perform ileocolonoscopy and esophagogastroduodenoscopy, since 50% have upper involvement, using the SES-CD (UCEIS/Mayo in CUP) and taking multiple biopsies. Initial labs should include inflammatory markers and fecal calprotectin and rule out intestinal infections. Treatment, induction, and maintenance of PID should be individualized and decided according to risk stratification. Follow-up should use PCDAI and PUCAI for the last 48 hours. Immunologists and geneticists should evaluate patients with early and infantile PID. Conclusion: A consensus guideline is provided with evidence-based recommendations on timely and safe diagnosis and treatments in patients with ILD.
RESUMO
Abstract Autoimmune gastritis is an underdiagnosed disease in the pediatric population due to the absence of specific signs and symptoms and late clinical manifestations. Iron deficiency anemia has recently been identified as an early hematological manifestation, allowing an early diagnostic approach. We present the case of a Colombian teenager, with no history of autoimmunity, with refractory iron deficiency. He underwent extension studies; biopsies and serology compatible with autoimmune gastritis were documented, requiring parenteral iron in its evolution. This pathology is underdiagnosed in our context since early diagnosis requires a high index of suspicion to prevent associated complications.
Resumen La gastritis autoinmune es una enfermedad subdiagnosticada en la población pediátrica. Lo anterior se debe a la ausencia de signos y síntomas específicos y manifestaciones clínicas tardías. Recientemente se ha identificado la anemia ferropénica como una manifestación hematológica precoz, lo que permite un enfoque diagnóstico temprano. Se presenta el caso de un adolescente colombiano, sin antecedentes de autoinmunidad, con ferropenia refractaria, en el que se realizaron estudios de extensión y se documentaron biopsias y serología compatible con gastritis autoinmune, con requerimiento de hierro parenteral en su evolución. Esta patología es subdiagnosticada en nuestro medio, ya que el diagnóstico temprano requiere un alto índice de sospecha, lo que permite la prevención de las complicaciones asociadas.

Resumen: Introducción: Las últimas guías clínicas conjuntas de NASPGHAN y ESPGHAN en relación a la infección por H. pylori publicadas el año 2016, contienen 20 afirmaciones que han sido cuestionadas en la práctica respecto a su aplicabilidad en Latinoamérica (LA); en particular en relación a la preven ción del cáncer gástrico. Métodos: Se realizó un análisis crítico de la literatura, con especial énfasis en datos de LA y se estableció el nivel de evidencia y nivel de recomendación de las afirmaciones mas controversiales de las Guías Conjuntas. Se realizaron 2 rondas de votación de acuerdo a la técnica Delfi de consenso y se utilizó escala de Likert (de 0 a 4) para establecer el "grado de acuerdo" entre un grupo de expertos de SLAGHNP. Resultados: Existen pocos estudios en relación a diagnóstico, efectividad de tratamiento y susceptibilidad a antibióticos de H. pylori en pacientes pediátricos de LA. En base a estos estudios, extrapolaciones de estudios de adultos y la experiencia clínica del panel de expertos participantes, se realizan las siguientes recomendaciones. Recomendamos la toma de biopsias para test rápido de ureasa e histología (y muestras para cultivo o técnicas moleculares, cuando estén disponibles) durante la endoscopia digestiva alta sólo si en caso de confirmar la infección por H. pylori, se indicará tratamiento de erradicación. Recomendamos que centros regionales seleccio nados realicen estudios de sensibilidad/resistencia antimicrobiana para H. pylori y así actúen como centros de referencia para toda LA. En caso de falla de erradicación de H. pylori con tratamiento de primera línea, recomendamos tratamiento empírico con terapia cuádruple con inhibidor de bomba de protones, amoxicilina, metronidazol y bismuto por 14 días. En caso de falla de erradicación con el esquema de segunda línea, se recomienda indicar un tratamiento individualizado considerando la edad del paciente, el esquema indicado previamente y la sensibilidad antibiótica de la cepa, lo que implica realizar una nueva endoscopía con extracción de muestra para cultivo y antibiograma o es tudio molecular de resistencia. En niños sintomáticos referidos a endoscopía que tengan antecedente de familiar de primer o segundo grado con cáncer gástrico, se recomienda considerar la búsqueda de H. pylori mediante técnica directa durante la endoscopia (y erradicarlo cuando es detectado). Con clusiones: La evidencia apoya mayoritariamente los conceptos generales de las Guías NASPGHAN/ ESPGHAN 2016, pero es necesario adaptarlas a la realidad de LA, con énfasis en el desarrollo de centros regionales para el estudio de sensibilidad a antibióticos y mejorar la correcta selección del tratamiento de erradicación. En niños sintomáticos con antecedente familiar de primer o segundo grado de cáncer gástrico, se debe considerar la búsqueda y erradicación de H. pylori.

Abstract Introduction: Eosinophilic esophagitis (EoE) is an emerging, chronic and immune-mediated disease. Clinically it is characterized by symptoms associated with esophageal dysfunction, and histologically by predominantly inflammatory eosinophil infiltrate. Objective: The aim of this study was to describe the clinical, endoscopic and histopathological characteristics of children and adolescents diagnosed with EoE at the Hospital Universitario Fundación Santa Fe de Bogotá between 2007 and 2017. Methods: This is a cross-sectional, descriptive and observational study that included patients under 18 years of age with histopathological diagnoses of EoE. Results: Forty-six patients were included, 31 were male, and the average age was 11.8 years (range 11 months - 18 years). Seventy percent presented abdominal pain, 37% presented heartburn, 28% suffered vomiting, 22% had nausea and dysphagia. The most common antecedents were asthma (41%), allergic rhinitis (37%), gastroesophageal reflux disease (22%) and atopic dermatitis (15%). The most frequent endoscopic finding consisted of whitish exudates found in 35% of the cases. Endoscopic suspicion of EoE was described in 50% of the cases. The histopathological study showed 15 to 40 eosinophils per high power field (HPF) in 52%, 41-60/HPF in 19.5%, and 61-80/HPF in 15.2%. Hyperplasia of the basal lamina was found in 95.6% of the cases. Conclusions: The majority of patients were adolescents (69%), the most frequent symptom was abdominal pain (70%), and 40% of cases had histories of atopy. Only 50% had endoscopic findings suggestive of EoE. This study is the first clinical and pathological analysis of EoE cases in children and adolescents in Colombia.

Resumen Introducción: la alergia a la proteína de leche de vaca (APLV) es la alergia alimentaria más frecuente en el primer año de vida. La evidencia actual acerca de la respuesta a una fórmula extensamente hidrolizada (FEH) a base de suero es insuficiente. Objetivo: determinar los desenlaces clínicos en lactantes con APLV a una FEH a base de suero (Nutrilón Pepti Junior®). Metodología: estudio retrospectivo, tipo serie de casos. Se incluyeron lactantes (≤12 meses) con APLV valorados en la consulta externa entre enero de 2011 y octubre de 2015 en un servicio de gastroenterología pediátrica. La información de datos demográficos, manifestaciones digestivas, tiempo de inicio de síntomas, antropometría y respuesta clínica a la fórmula fue abstraída a partir de la revisión de la historia clínica. Se comparó el estado nutricional de los pacientes en la primera y en la consulta de control un año después utilizando la prueba t de Student. Resultados: se incluyeron 40 lactantes (42,5% varones) de 3,3 ± 2,4 meses, con síntomas como vómito/regurgitación, cólico/irritabilidad y deposición con sangre. Los antecedentes familiares y perinatales relacionados con el desarrollo de APLV fueron la ingesta de biberón en la primera semana de vida: 27 (67,5%), madre ≥30 años: 33 (82,5%), atopia en 2 familiares: 12 (30%) y parto por cesárea: 30 (75%). 37 (92,5%) pacientes mostraron una respuesta positiva a una FEH a base de suero, mientras que 3 (7,5%) pacientes no respondieron y requirieron una fórmula a base de aminoácidos (FAA) libres. Los z-score de peso/edad: -0,69 ± 1,03 y peso/talla: -0,79 ± 1,00 de la primera consulta mejoraron en el seguimiento posterior al año (p <0,05): peso/edad: -0,27 ± 0,98 y peso/talla: -0,14 ± 0,98. Conclusión: se encontró recuperación nutricional y tolerancia a la leche de vaca en un alto porcentaje de lactantes con APLV que recibieron una FEH a base de suero.
Abstract Introduction: Cow's milk protein allergies (CMPA) are the most frequent food allergies in the first year of life. Current evidence about responses to an extensively hydrolyzed serum based formula is insufficient. Objective: This study's objective was to determine clinical outcomes in infants with CMPA to an extensively hydrolyzed serum based formula (Nutrilón Pepti Junior®). Methodology: This is a retrospective case series study of infants 12 months old or younger diagnosed with CMPA in the outpatient clinic of a pediatric gastroenterology service between January 2011 and October 2015. Information including demographic data, digestive manifestations, time of onset of symptoms, anthropometry and clinical responses to formula was abstracted from a review of clinical histories. Patients' nutritional statuses at first and one year follow-up consultations were compared using Student's t-test. Results: Forty infants (42.5% males) whose average age was 3.3 ± 2.4 months were included. Their symptoms included vomiting/regurgitation, colic/irritability and bloody stools. Family and perinatal history related to the development of CMPA included bottle feeding in the first week of life (27 patients, 67.5%), mothers who were thirty years of age or older (33 patients, 82.5%), atopy in two family members (12 patients, 30 %) and cesarean deliveries (30 patients, 75%). Thirty-seven patients (92.5%) responded positively to an extensively hydrolyzed serum based formula while three patients (7.5%) did not respond and required a milk-free amino acid based formula. The first consultation z-score of P/E was -0.69 ± 1.03 while the first consultation z-score of P/T was -0.79 ± 1.00. These improved at the one year follow-up to (p <0.05) P/E: -0.27 ± 0.98 and P/T: -0.14 ± 0.98, respectively. Conclusion: Nutritional recovery and tolerance to cow's milk was found in a high percentage of infants with CMPA who received an extensively hydrolyzed serum based formula.

Resumen Objetivo: determinar la prevalencia de prescripción de terapia supresora de ácido (TSA) conformada por los inhibidores de la bomba de protones (IBP) y los antagonistas de los receptores H2 (AR-H2) en pacientes adultos hospitalizados en el Hospital Universitario Fundación Santa Fe de Bogotá (HU-FSFB) que no corresponda con las indicaciones de las guías de práctica clínica (GPC). Métodos: estudio observacional descriptivo de corte transversal que incluyó pacientes adultos hospitalizados en el HU-FSFB con prescripción de TSA de novo, determinando las indicaciones de la TSA y comparándolas con las indicaciones validadas. Se excluyeron los pacientes con prescripción o consumo previo de TSA durante 2 semanas y pacientes internados en la unidad de cuidados intensivos (UCI) o con hospitalización menor de un día. Resultados: entre enero y julio de 2015 se incluyeron 306 pacientes con un promedio de edad de 56,6 (+38) años, con una prevalencia de prescripción de TSA sin indicación basada en la evidencia del 59,5%. Las indicaciones no basadas en la evidencia más comunes fueron profilaxis de sangrado por úlcera gastrointestinal en pacientes de bajo riesgo (64,9%) y causa no establecida (13,7%). Se encontró una asociación estadísticamente significativa entre el tiempo de hospitalización menor de 7 días (odds ratio [OR]: 2,39; intervalo de confianza [IC] 95%: 1,4-3,9) y edad menor de 60 años (OR: 1,9; IC 95%: 1,2-3,03) con prescripción inapropiada de TSA. Conclusión: existe una alta prevalencia (59,5%) de prescripción inapropiada de TSA en pacientes adultos hospitalizados con asociación positiva en menores de 60 años y corta hospitalización en el HU-FSFB.
Abstract Objective: This study's objective was to determine the prevalence of prescriptions of acid suppression therapy consisting of proton pump inhibitors (PPIs) or H2 receptor antagonists (H2RA) in adult patients hospitalized in the Hospital Universitario - Fundación Santa Fe de Bogotá (HU-FSFB - Santa Fe de Bogotá Foundation University Hospital) that are not in accordance with clinical practice guidelines (CPG). Methods: This is a cross-sectional descriptive observational study that included adult patients hospitalized in the HU-FSFB who were treated with acid suppressors for the first time. We determined the indications for prescriptions used and compared them with validated indications. We excluded patients who had previously taken acid suppressants for two weeks, patients admitted to the intensive care unit, and patients who stayed in the hospital for less than one day. Results: Between January and July 2015, 306 patients with an average age of 56.6 years were included in this study. The prevalence of acid suppression prescriptions without indications based on the evidence was 59.5%. The most common indications were prophylaxis of bleeding due to gastrointestinal ulcers in low risk patients (64.9%) and cause not established (13.7%). Statistically significant associations were found between inappropriate prescription of acid suppression and hospitalization times of less than seven days (OR: 2.39 95% CI 1.4-3.9) and ages of less than 60 years (OR: 1.9 95% CI 1.2-3.03). Conclusion: The prevalence of inappropriate prescriptions of acid suppression for adult patients hospitalized in the HU-FSFB was (59.5%). There were positive associations with ages under 60 years and short hospital stays.

Resumen Objetivo: este estudio caracteriza la diversidad de los genes de virulencia cagA (gen asociado con la citotoxina A) y vacA (citotoxina vacuolizante) en pacientes colombianos para determinar posibles asociaciones entre estos 2 genes y la severidad de los hallazgos endoscópicos teniendo en cuenta todos los genotipos reportados para el gen vacA (s, m e i). Materiales y métodos: Helicobacter pylori fue detectado por cultivo y por métodos moleculares en biopsias de 62 pacientes. Los genotipos de cagA y vacA (m/i/s) se determinaron por reacción en cadena de la polimerasa (PCR) y secuenciación. Resultados: se aislaron 124 cepas de 62 pacientes; de estas, el 48,5% (n = 48) fueron vacA s2/m2/i2-cagA (-) presente en su mayoría en pacientes con gastritis folicular; mientras el 32,3% (n = 32) fueron vacA s1/m1/i1-cagA (+) presentes mayormente en pacientes con gastritis folicular, gastritis crónica y posible metaplasia. Se encontró una asociación significativa entre la presencia de cagA y el genotipo vacA s1/m1/i1 y la ausencia de cagA y el genotipo vacA s2/m2/i2 (p <0,001). No se encontró una asociación significativa entre la severidad de los hallazgos endoscópicos y el estatus cagA-vacA de las cepas. Conclusión: se encontró una baja prevalencia de cepas cagA (+), el estatus cagA-vacA no es un predictor de riesgo en la población estudiada y la presencia de infecciones heterogéneas sin tropismo sugieren la necesidad de tomar biopsias tanto del cuerpo como del antro del estómago en la práctica clínica rutinaria.
Abstract Objective: This study characterizes the diversity of cagA and vacA virulence genes in Colombian patients to determine possible associations between them and the severity of endoscopic findings. It considers all four genotypes reported for the vacA gene (s, m and i). Materials and methods: Helicobacter pylori was detected in biopsies of 62 patients through culturing and by molecular methods. Genotypes of cagA and vacA (m/i/s) were determined by PCR and sequencing. Results: One hundred twenty four strains from 62 patients were isolated. Of these, 48.5% (n = 48) were vacA s2/m2/i2 - cagA (-) which were mostly found in patients with follicular gastritis; 32.3% (n = 32) were vacA s1/m1/i1-cagA (+) which were mostly found in patients with follicular gastritis, chronic gastritis and possible metaplasia. Significant associations were found between the presence of cagA and the vacA s1/m1/i1 genotype and the absence of cagA and the vacA s2/m2/i2 genotype (p <0.001). No significant association was found between the severity of endoscopic findings and the cagA-vacA status of the strains. Conclusion: We found a low prevalence of cagA (+) strains, the cagA-vacA status is not a predictor of risk in this population. Moreover, the presence of heterogenous infections without tropism suggests a need for biopsies from both the corpus and the antrum of the stomach in routine clinical practice.

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.
