Retrospective study of budesonide in children with eosinophilic gastroenteritis.

BACKGROUND: The effectiveness of budesonide (BUD), a locally active steroid, on eosinophilic gastroenteritis (EGE) is not well understood. This study is to retrospectively evaluate the efficacy of BUD in children with EGE. METHODS: Forty-four children, diagnosed with EGE, were enrolled from 2013 to 2017 in our center. According to patients' preference, all the patients were treated with dietary elimination (DE) and montelukast therapy, or combined with prednisone (PRED)/BUD. Patients' clinical manifestations, treatments, and outcomes were reviewed from the medical records. Twenty-four patients (7 PRED, 7 BUD, 10 DE) received therapy for ≥8 weeks, followed by repeat endoscopy and biopsies. Histological response was defined as <20 eos/hpf (eosinophils per high-power field). RESULTS: Significant number of patients in DE+PRED (6/7, 85.7%) and DE+BUD (6/7, 85.7%) groups achieved histological response than in the DE group (3/10.30%) (p = 0.024). Mean post-treatment peak eos/hpf in the DE+PRED group was 16.57 ± 6.85 vs. 10.00 ± 5.07 in the DE+BUD group vs. 36.60 ± 24.57 in the DE group (p = 0.009). Change of eos/hpf from pre- to post-treatment was -49.86 ± 45.02 vs. -34.29 ± 23.44 in the BUD group vs. -0.3 ± 23.95 in the DE group (p = 0.011). There were no significant differences between DE+PRED and DE+BUD groups (p = 0.470, p = 0.363, respectively). CONCLUSION: BUD is effective in the treatment of EGE and has similar effectiveness with PRED.

Efficacy of an elimination diet in a patient with eosinophilic gastroenteritis : a pediatric case with multiple food allergies.

Eosinophilic gastrointestinal disorders are chronic inflammatory diseases in which eosinophils highly infiltrate into gastrointestinal tissue, resulting in gastrointestinal dysfunction. Here, we report a case of pediatric eosinophilic gastroenteritis (EGE). A 7-year-old boy with multiple food allergies (cow milk, hen's egg, fish,shellfish, and chicken) was admitted to our hospital because of continuous abdominal pain and vomiting. His soy allergy had been diagnosed to have oral tolerance based on an oral food challenge at the age of 6 years. He was diagnosed with EGE based on biopsy findings showing eosinophilic infiltration ( 20 eosinophils per high-power field) into the gastrointestinal mucosa. A diet eliminating soy, wheat, beef, pork, rice, and sesame in addition to the food that had already been eliminated and oral corticosteroids improved his symptoms and peripheral eosinophilia. A relapse of both abdominal pain and peripheral eosinophilia after the reintroduction of soy or pork identified them as foods causative of EGE. This report highlights the utility of elimination diets in improving EGE symptoms and the subsequent reintroduction of offending foods in identifying causative foods. Furthermore,EGE onset should be considered when introducing potentially allergic food in the management of food allergy. J. Med. Invest. 66 : 201-204, February, 2019.

Hematochezia caused by eosinophilic proctocolitis in a newborn before oral feeding: a case report.

BACKGROUND: Hematochezia is a frequent symptom in early infancy. However, it occurs very rarely within the immediate neonatal period, and its occurrence before any oral intake is particularly rare. Because of the "congenital" presentation of hematochezia in our patient, we initially considered our case to be a non-classical, potentially severe type of food protein-induced allergic proctocolitis. This diagnosis needs to be confirmed by an abnormal oral challenge test once the hematochezia has disappeared. If such a challenge cannot demonstrate an allergic origin, then the etiology of the hematochezia could be a neonatal transient eosinophilic colitis. Only two similar cases have been described so far. CASE PRESENTATION: We report the case of a black baby boy of African origin born at 36 weeks 5 days of gestational age who presented with massive hematochezia immediately after birth. A rectosigmoidoscopy revealed a severe inflammation associated with diffuse eosinophilic infiltration on biopsy. His clinical outcome was favorable after introduction of an amino acid formula diet. We initially considered our case to be a non-classical, potentially severe type of food protein-induced allergic proctocolitis but reintroduction of standard formula milk at the age of 3 months was successful. So, our patient is the first newborn in Europe who fits the diagnosis of "neonatal transient eosinophilic colitis." CONCLUSIONS: We discuss the possible etiology of "congenital" eosinophilic inflammation of the distal colon and conclude that hematochezia in well-looking neonates, in the absence of negative challenge tests later on, is more likely to be a neonatal transient eosinophilic colitis than an allergic proctocolitis. This new entity could be more frequent than previously thought, changing our medical care strategies for this kind of neonatal symptom.

Eficacia y seguridad de fórmula a base de aminoácidos libres en pacientes pediátricos con gastroenteropatías eosinofílicas / Efficacy and safety of free amino acid formula in pediatric patients with eosinophilic gastroenteropathy

INTRODUCCIÓN: Antecedentes: El presente dictamen expone la evaluación de tecnología de la eficacia y seguridad de la fórmula en base a aminiácidos libres (FAA) respecto a su uso en pacientes con gastroenteropatias eosinofilicas (GE). Aspectos Generales: Las gastroenteropatias eosinofilicas (GE) son un conjunto de enfermedades que se caracterizan por la infiltración de eosinófilos en diversos órganos del cuerpo. Dentro del grupo de las GE se encuentran la esofagitis eosinofílica (EoE) y las gastroenteritis eosinfílicas (EGE). Tecnologia Sanitaria de Interés: Las fórmulas en base a aminoácidos lilbres (FAA) son fórmulas hipoalergénicas que han sido diseñadas para pacientes que requieren ingerir porteínas en su estructura más simples. Las proteínas que componen estas fórmulas están en forma de L-aminiácidos (Nutrition 2000). DEbido a ello, las FAA son llamadas también fórmulas elementales. Estas fórmulas tienen un perfil nutricional completo ya que, además de aportar porteínas, aportan también carbohidratos, lípidos y micronutrientes (Nutrition 2000). La composición nutricional de las FAA varía según el grupo etario y la enfermedad base de la población para la cual están dirigidas. METODOLOGIA: Estrategia de Búsqueda: Se realizó una búsqueda de la literatura con respecto a la eficacia y seguridad del uso de fórmulas en base a aminoácidos libres (FAA) en pacientes con gastroenteropatias eosinofílicas (GE). Se dio preferencia a guías de práctica clínica, revisiones sistemáicas con o sin meta-análisis y ensayos clínicos aleatorizados. Asimismo, se consideró extraer información con una estrategia de "bola de nieve" mediante la revisión de las referencias bibliográficas bibliográficas de las guías de páctica clínica, revisiones seleccionadas. RESULTADOS: Sinopsis de la Evidencia: Se realizó la búsqueda bibliográfica y de evidencia científica para el sustento del uso de fórmula en base de aminoácidos libre en pacientes pediátricos con gastroenteropatías eosinofílicas. Así, luego de revisar un total de 520 referencias resultados de la búsqueda bibliográfica, se seleccionaron 18 estudios relevantes. Cuatro referencias fueron selecionadas para ser analizadas. CONCLUSIONES: En la presente evaluación de tecnología sanitaria se presenta la evidencia recabada sobre el uso de la fórmula en base a aminoácidos libres (FAA) en pacientes con gastroenteropatías eosinofilicas (GE). La evidencia encontrada que evalúa el uso de la FAA en pacientes con GE es escasa. Se ha identificado evidencia proveniente de una guía de práctica clínica (GPC) y tres estudios observacionales retrospectivos que evaluán el uso de la FAA en pacientes con esofagitis eosinofílica (EoE). Ninguno de los estudios evaluó el uso de la FAA en pacientes con otros tipos de GE, como gastritis, enteritis y/o colitis eosinofílica. El Instituto de Evaluación de Tecnologías en Salud e Investigación-IETSI, aprueba el uso de las FAA en pacientes con GE. El presente Dictamen Preliminar tiene una vigencia de dos años a partir de la fecha de publicación.

High Prevalence of Eosinophilic Gastrointestinal Disease in Children With Intestinal Failure.

OBJECTIVES: The aim of the present study was to describe the prevalence and clinical features of gastrointestinal (GI) eosinophilic inflammation among pediatric patients with intestinal failure (IF). METHODS: Medical records of all patients studied in our institution's IF program who underwent GI endoscopy over a 15-year period were reviewed, and clinical, pathologic, nutrition, and laboratory data collected. RESULTS: One hundred five patients underwent 208 GI endoscopic procedures with biopsy. The overall prevalence of eosinophilic inflammation, defined as increased eosinophils in at least 1 tissue type on at least 1 endoscopy, was 39 of 105 (37%). The tissue-specific prevalence of eosinophilic inflammation ranged widely, with the colon/rectosigmoid being the most common (18/68, 26%), followed by the esophagus (17/83, 20%), ileum (9/54, 17%), duodenum (4/83, 5%), and stomach (3/83, 4%). Higher peripheral eosinophil count and hematochezia were associated with eosinophilic inflammation in the colon (P = 0.002 and 0.0004, respectively). The use of a strict elemental diet for 3 months before endoscopy was not associated with a decreased frequency of eosinophilic inflammation in any tissue. CONCLUSIONS: Eosinophilic inflammation is a common histopathological finding in patients with IF. Colonic eosinophilic inflammation is associated with clinical symptoms of GI blood loss, and peripheral eosinophilia, and was not abrogated by a strict elemental diet.

Perforated duodenal ulcer: An unusual manifestation of allergic eosinophilic gastroenteritis.

Spontaneous perforation of a duodenal ulcer secondary to allergic eosinophilic gastroenteritis (EGE) has not been previously reported. We present such a case in a teenager who presented with peritonitis. After exploration and operative repair of his ulcer, he continued to experience intermittent abdominal pain, and further evaluation revealed eosinophilic gastroenteritis in the setting of multiple food allergies. His EGE resolved after adhering to a restrictive diet. Both duodenal ulcers and EGE are very rarely seen in pediatric patients. EGE has a variable presentation depending on the layer(s) of bowel wall affected and the segment of the gastrointestinal tract that is involved. Once diagnosed, it may respond to dietary changes in patients with recognized food allergies, or to steroids in patients in whom an underlying cause is not identified. Our case highlights the need to keep EGE in the differential diagnosis when treating pediatric patients with duodenal ulcers. The epidemiology, pathophysiology, and treatment of EGE are also discussed, along with a review of the current literature.

Eosinophilic gastrointestinal disease and inflammatory bowel disease in children: is it a disease continuum?

Eosinophilic gastrointestinal disease (EGID) and inflammatory bowel disease (IBD) are two distinct disorders that share some clinical manifestations but have different diagnostic criteria. In this article, we reviewed the clinical data of three children with EGID who later developed IBD. This study is a retrospective case note review that was conducted between 2007 and 2012. EGID seems to precede IBD in some subsets of children in whom the diagnosis of IBD may take a few years to fully develop.

Eosinophilic gastritis in children: clinicopathological correlation, disease course, and response to therapy.

OBJECTIVES: Eosinophilic gastritis (EG), defined by histological criteria as marked eosinophilia in the stomach, is rare, and large studies in children are lacking. We sought to describe the clinical, endoscopic, and histopathological features of EG, assess for any concurrent eosinophilia at other sites of the gastrointestinal (GI) tract, and evaluate response to dietary and pharmacological therapies. METHODS: Pathology files at our medical center were searched for histological eosinophilic gastritis (HEG) with ≥70 gastric eosinophils per high-power field in children from 2005 to 2011. Pathology slides were evaluated for concurrent eosinophilia in the esophagus, duodenum, and colon. Medical records were reviewed for demographic characteristics, symptoms, endoscopic findings, comorbidities, and response to therapy. RESULTS: Thirty children with severe gastric eosinophilia were identified, median age 7.5 years, 14 of whom had both eosinophilia limited to the stomach and clinical symptoms, fulfilling the clinicopathological definition of EG. Symptoms and endoscopic features were highly variable. History of atopy and food allergies was common. A total of 22% had protein-losing enteropathy (PLE). Gastric eosinophilia was limited to the fundus in two patients. Many patients had associated eosinophilic esophagitis (EoE, 43%) and 21% had eosinophilic enteritis. Response to dietary restriction therapy was high (82% clinical response and 78% histological response). Six out of sixteen patients had persistent EoE despite resolution of their gastric eosinophilia; two children with persistent HEG post therapy developed de novo concurrent EoE. CONCLUSIONS: HEG in children can be present in the antrum and/or fundus. Symptoms and endoscopic findings vary, highlighting the importance of biopsies for diagnosis. HEG is associated with PLE, and with eosinophilia elsewhere in the GI tract including the esophagus. The disease is highly responsive to dietary restriction therapies in children, implicating an allergic etiology. Associated EoE is more resistant to therapy.

Eosinophilic colitis in infants / Colite eosinofílica em lactentes

OBJECTIVE: To review the literature for clinical data on infants with allergic or eosinophilic colitis. DATA SOURCE: MEDLINE search of all indexes was performed using the words ''colitis or procto-colitis and eosinophilic'' or ''colitis or proctocolitis and allergic'' between 1966 and February of 2013. All articles that described patients' characteristics were selected. DATA SYNTHESIS: A total of 770 articles were identified, of which 32 met the inclusion criteria. The 32 articles included a total of 314 infants. According to the available information, 61.6% of infants were male and 78.6% were younger than 6 months. Of the 314 patients, 49.0% were fed exclusively breast milk, 44.2% received cow's milk protein, and 6.8% received soy protein. Diarrheal stools were described in 28.3% of patients. Eosinophilia was found in 43.8% (115/263) of infants. Colonic or rectal biopsy showed infiltration by eosinophils (between 5 and 25 perhigh-power field) in 89.3% (236/264) of patients. Most patients showed improvement with theremoval of the protein in cow's milk from their diet or the mother's diet. Allergy challenge tests with cow's milk protein were cited by 12 of the 32 articles (66 patients). CONCLUSIONS: Eosinophilic colitis occurs predominantly in the first six months of life and in males. Allergy to cow's milk was considered the main cause of eosinophilic colitis. Exclusion of cow'smilk from the diet of the lactating mother or from the infant's diet is generally an effective therapeutic measure. .

Effect of six-food elimination diet on clinical and histologic outcomes in eosinophilic esophagitis.

BACKGROUND & AIMS: In children, eosinophilic esophagitis (EE) is predominantly, but not exclusively, a food-hypersensitivity disorder. A crystalline amino acid-based elemental diet (ELED) formula currently remains the most effective nutritional treatment in inducing clinical and histologic remission. However, compliance with an exclusive, poor-tasting liquid formulation is difficult. METHODS: This retrospective observational study assessed the short-term clinical and histologic responses of 2 cohorts of children with EE evaluated during 2 different time periods: one was treated with the standard 6-food elimination diet (SFED) and the other was treated with ELED. Of the 60 children who met the inclusion criteria and were compliant with the dietary protocol, 35 were treated with a diet excluding cow-milk protein, soy, wheat, egg, peanut, and seafood while allowing all other table foods and 25 were treated exclusively with ELED. Repeat esophageal biopsy specimens were obtained at least 6 weeks later. RESULTS: Twenty-six of 35 (74%) in the SFED group and 22 of 25 (88%) in the ELED group achieved significant improvement of esophageal inflammation (

Eosinophilic esophagitis: a 10-year experience in 381 children.

BACKGROUND & AIMS: Eosinophilic esophagitis (EoE) is a disorder characterized by a severe, isolated eosinophilic infiltration of the esophagus unresponsive to aggressive acid blockade but responsive to the removal of dietary antigens. We present information relating to our 10-year experience in children diagnosed with EoE. METHODS: We conducted a retrospective study between January 1, 1994, and January 1, 2004, to evaluate all patients diagnosed with EoE. Clinical symptoms, demographic data, endoscopic findings, and the results of various treatment regimens were collected and evaluated. RESULTS: A total of 381 patients (66% male, age 9.1 +/- 3.1 years) were diagnosed with EoE: 312 presented with symptoms of gastroesophageal reflux; 69 presented with dysphagia. Endoscopically, 68% of patients had a visually abnormal esophagus; 32% had a normal-appearing esophagus despite a severe histologic esophageal eosinophilia. The average number of esophageal eosinophils (per 400 x high power field) proximally and distally were 23.3 +/- 10.5 and 38.7 +/- 13.3, respectively. Corticosteroids significantly improved clinical symptoms and esophageal histology; however, upon their withdrawal, the symptoms and esophageal eosinophilia recurred. Dietary restriction or complete dietary elimination using an amino acid-based formula significantly improved both the clinical symptoms and esophageal histology in 75 and 172 patients, respectively. CONCLUSIONS: Medications such as corticosteroids are effective; however, upon withdrawal, EoE recurs. The removal of dietary antigens significantly improved clinical symptoms and esophageal histology in 98% of patients.

Treatment of eosinophilic esophagitis with specific food elimination diet directed by a combination of skin prick and patch tests.

BACKGROUND: Eosinophilic esophagitis (EE) is a recently described disorder identified in patients with symptoms suggestive of gastroesophageal reflux disease (GERD) but unresponsive to conventional reflux therapies. Therapies have included corticosteroids, elemental diet, and diet restriction. We report our experience with skin prick and atopy patch testing and food elimination diets in patients diagnosed as having EE. OBJECTIVE: To identify food antigens that cause EE and the characteristics of patients who respond to food elimination vs those who are unresponsive. METHODS: Patients diagnosed as having EE had restricted diets based on skin prick and atopy patch testing results. Additional biopsies were performed after 4 to 8 weeks of restricted diet. Demographics, atopic tendencies, and food antigens were identified retrospectively in our food allergy database. RESULTS: A total of 146 patients diagnosed as having EE were evaluated with skin prick and atopy patch testing. Thirty-nine patients had unequivocal demonstration of food causing EE, with normalization of biopsy results on elimination and reoccurrence on reintroduction. An additional 73 patients, for a total 112 (77%) of 146 patients, had resolution of their EE as demonstrated by biopsy results. Fifteen (10%) of 146 patients were nonresponders manifested by no significant reduction in esophageal eosinophils despite restricted diet based on skin prick and atopy patch testing. Egg, milk, and soy were identified most frequently with skin prick testing, whereas corn, soy, and wheat were identified most frequently with atopy patch testing. CONCLUSION: In more than 75% of patients with EE, both symptoms and esophageal inflammation can be significantly improved with dietary elimination of foods. Skin prick and atopy patch testing can help identify foods in most patients.

Successful medical treatment of two patients with eosinophilic oesophagitis.

BACKGROUND/PURPOSE: Significant oesophageal eosinophilia is associated with oesophagitis and gastroesophageal reflux (GER). Eosinophilic oesophagitis is a rare disease that causes thickening of the oesophageal wall, narrowing of the oesophageal lumen, and severe motor disturbance. METHODS AND RESULTS: Two 12 yr-old patients with eosinophilic oesophagitis were studied prospectively. Clinical and investigation details are presented. Elemental formula was administered until complete remission of disease. Final outcome was assessed after 3 months on regular diet with exclusion of specific allergic components. Both patients responded to the dietary manipulation. CONCLUSIONS: Eosinophilic oesophagitis must be included in the differential diagnosis when dealing with oesophageal strictures of unknown or unclear aetiology. Elimination diet therapy plays a crucial role in ameliorating the course of the illness. Blood eosinophilia correlates with therapeutic response and with improvement of the disease.

Proctocolitis in breast fed infants: a contribution to differential diagnosis of haematochezia in early childhood.

Dietary protein induced proctocolitis in exclusively breast fed infants is rarely taken into consideration as a cause of rectal bleeding or blood streaked stool in the neonatal period and early infancy. Eleven babies are presented in whom it is believed that bleeding through the rectum was due to proctocolitis as a result of allergy triggered by cows' milk protein transferred to the infants via the breast milk. Colonoscopy was performed in five infants, revealing benign eosinophilic proctocolitis. Standard treatment was the exclusion of the allergen from the mother's diet. Resolution of visible rectal bleeding took place within 72 to 96 hours after elimination of the offending protein from the mother's diet.

Multiple esophageal rings: an association with eosinophilic esophagitis: case report and review of the literature.

Esophagitis may present endoscopically with erythema, edema, loss of vascular pattern, friability, and ulceration of the esophageal mucosa. Left untreated, chronic esophagitis may result in stricture formation. The presence of multiple concentric rings involving the entire esophagus has been cited as a chronic form of esophagitis. We present a case of an 8-yr-old boy with multiple concentric esophageal rings and histological evidence of eosinophilic esophagitis, who failed medical antireflux treatment and responded to an elimination diet.

[Eosinophilic gastroenteritis in food allergy]. / Eosinophile Gastroenteritis bei Nahrungsmittelallergie.

A 23-year-old woman suffered from chronic abdominal pain, nausea and diarrhea. The clinical symptoms particularly increased after ingestion of several foods. Laboratory investigation revealed a moderate eosinophilia in peripheral blood, elevated serum IgE-level and specific IgE against food allergens in radioallergosorbent testing. The patient exhibited exsudative ascites with eosinophiles. CT scan revealed a thickened wall of the small bowel. There was no evidence of a parasitic or extraintestinal disease. Endoscopically, the gastrointestinal tract appeared normal. Histological examinations of biopsies of the gastrointestinal tract led to the diagnosis of eosinophilic gastroenteritis. Under an elimination diet the patient is symptom-free since 16 months without ascites.
