Eosinophilic gastroenteritis is a rare condition of unknown etiology characterized by peripheral eosinophilia, eosinophilic infiltration of the gastrointestinal tract, and gastrointestinal symptoms. Eosinophilic gastroenteritis is generally classified according to the Klain classification: predominant mucosal, muscular, and subserosal disease. Mucosal involvement may result in abdominal pain, nausea, vomiting, diarrhea, weight loss, anemia, protein-losing enteropathy, and intestinal perforation. Patients with muscular layer disease generally have obstructive symptoms. Subserosal eosinophilic infiltration may result in development of eosinophilic ascites. Most commonly, the stomach, duodenum, and small bowel are involved. A 13-year-old girl came to our hospital presenting with chronic, intermittent abdominal pain. She showed peripheral eosinophilia and biopsy specimen of the duodenum revealed eosinophilic infiltration of the mucosal layer. We here report a case of eosinophilic gastroenteritis.

Eosinophilic gastroenteritis is a rare disease characterized by prominent eosinophilic tissue infiltration of the gastrointestinal tract. Here, we report a case of eosinophilic gastroenteritis in an 18-year-old patient with prolonged nephrotic syndrome who presented with abdominal pain and peripheral hypereosinophilia. During the previous 2 years, he had visited local Emergency Department several times because of epigastric pain and nausea. He had been treated with steroid-dependent nephrotic syndrome since 3 years of age. Tests ruled out allergic and parasitic disease etiologies. Gastroduodenoscopy with biopsy revealed marked eosinophilic infiltration in the duodenum. Renal biopsy findings indicated minimal change disease spectrum without eosinophilic infiltration. The oral deflazacort dosage was increased, and the patient was discharged after abdominal pain resolved. To our knowledge, this is the first report of eosinophilic gastroenteritis in a patient with minimal change disease.

Eosinophilic gastroenteritis is a rare disease occurring especially in children, and shows various nonspecific presentations with infiltration of eosinophils in the gastrointestinal organs. The pathophysiology of eosinophilic gastroenteritis is not yet clearly known, but allergic reactions are suspected to be related with the disease. Eosinophilic gastroenteritis is categorized into the mucosal, muscularis and subserosal types based on which layer of the intestinal wall is involved. There are different clinical manifestations according to the involved layer. Most cases to date have responded well to steroid therapy. In this study, we diagnosed and treated a case of non-IgE-mediated, subserosal eosinophilic gastroenteritis in a child with abdominal pain, diarrhea and ascites.

Eosinophilic gastrointestinal disease (EGID), a chronic allergic condition characterized by dense infiltration of eosinophils in the digestive tract, is classified into two types, eosinophilic esophagitis (EoE), which features dense infiltration of eosinophils in the esophageal epithelial layer, and eosinophilic gastroenteritis (EGE), in which the entire digestive tract including the esophagus may be involved. Patients with EoE only have esophageal symptoms, since the other parts of the digestive tract are not involved. On the other hand, 80% of EGE patients have lesions in the small intestine. The esophageal epithelial layer in healthy individuals has no or negligible infiltration by eosinophils, while the small intestinal mucosal layer, especially the distal small intestinal mucosa, can show dense eosinophil infiltration even in the absence of disease. Therefore, histological changes observed in cases of EGE are not qualitative but rather quantitative, as compared to EoE, which has qualitative histopathological changes, indicating important pathogenetic differences between the types. Comparisons of clinical, laboratory, and morphological characteristics between EoE and EGE have revealed several interesting differences. Both EoE and EGE patients are frequently affected by atopic diseases, such as bronchial asthma and allergic rhinitis, and elevated plasma levels of Th2 type cytokines and chemokines are also similarly seen in both. On the other hand, age at diagnosis differs, as the former is generally found in individuals from 30 to 50 years old, while the latter appears in all age groups. Additionally, 80% of patients with EoE are male as compared to only 50% of those with EGE. Furthermore, approximately 60% of patients with EoE respond favorably to proton pump inhibitor (PPI) administration, whereas EGE patients rarely show a response to PPIs. Nevertheless, both diseases show a similarly favorable response to a six foods elimination diet and glucocorticoid administration. These similarities and differences of EoE and EGE provide important clues for understanding the pathogenesis of these EGID types.

Eosinophilic gastroenteritis is a rare clinicopathologic entity of unknown etiology with a variety of digestive symptoms. The pathogenesis is poorly understood. Diagnostic criteria include demonstration of eosinophilic infiltration of the affected bowel wall, lack of evidence of extraintestinal disease, and exclusion of various disorders that could mimic similar conditions. The disease might involve any area of the gastrointestinal tract from the esophagus to the rectum, but the stomach and the proximal small bowel are most commonly affected. The clinical features depend on which layer and site are involved. We report the case of a 59-year-old male patient with a 3-week history of post-prandial vomiting with malnutrition and weight loss. An abdominopelvic CT showed a gastric outlet obstruction with diffuse wall thickening, as with linitis plastica. Three gastrofiberscopic biopsies showed chronic gastritis. We carried out a radical total gastrectomy with D2 lymph node dissection. The pathologic report revealed a mural type eosinophilic gastritis with a marked hypertrophic scar formation at the proper muscle layer. We report this case with a brief review of the literature.

Purpose: In East Asian countries, there are only a few epidemiologic studies of eosinophilic esophagitis (EoE) and no studies in children. We investigated the incidence and compared the clinical characteristics of EoE and eosinophilic gastroenteritis involving the esophagus (EGEIE) in Korean children. Methods: A total of 910 children, who had symptoms of esophageal dysfunction, from 10 hospitals in Korea were included. EoE was diagnosed according to diagnostic guidelines and EGEIE was diagnosed when there were >15 eosinophils in the esophagus per high power field (HPF) and >20 eosinophils per HPF deposited in the stomach and duodenum with abnormal endoscopic findings. Results: Of the 910 subjects, 14 (1.5%) were diagnosed with EoE and 12 (1.3%) were diagnosed with EGEIE. Vomiting was the most common symptom in 57.1% and 66.7% of patients with EoE and EGEIE, respectively. Only diarrhea was significantly different between EoE and EGEIE (p=0.033). In total, 61.5% of patients had allergic diseases. Exudates were the most common endoscopic findings in EoE and there were no esophageal strictures in both groups. The median age of patients with normal endoscopic findings was significantly younger at 3.2 years, compared to the median age of 11.1 years in those with abnormal endoscopic findings (p=0.004). Conclusion: The incidence of EoE in Korean children was lower than that of Western countries, while the incidence of EGEIE was similar to EoE. There were no clinical differences except for diarrhea and no differences in endoscopic findings between EoE and EGEIE.

Objectives The aim of this study was to report an improvement on the symptoms of Eosinophilic Colitis (EC) by Yeoldahanso-tang.Methods The patient was diagnosed with Taeumin Ganyeol-paeJo Symptomatology and treated with Yeoldahanso-tang. The gastroendoscopy and eosinophilic infitration of mucosa of colitis are investigated. Also patient's subjective symptom of abdominal pain was scored using the Numerical Rating Scale(NRS) during the treatment period. And the number of defecation in a day is also used to decide the degree of colitis.Results and Conclusions The patient had been treated from December 13, 2014 to August 8, 2015. Eosinophilic infiltration of colon was disappeared after the treatment although chronic inflammation still existed. Subjective pain of abdominal pain was measured as NRS 6~8 at the beginning of the remedy, but diminished through the treatment sessions and became NRS 0 in the end. The number of defecation was in average 3, and at the endpoint it became 1. In conclusion, this study suggests that Sasang constitutional Medicine used for treating EC of Taeumin may be effective.

Purpose: The aim of the present study was to investigate the clinical features and outcome of eosinophilic gastroenteritis (EGE) in children. Methods: Our study enrolled 24 children who were diagnosed with EGE from 1993 to 2014 at the Department of Pediatrics, Seoul National University Children's Hospital. The patients' clinical manifestations, treatments, and outcomes were reviewed from the medical records. Results: The mean age at diagnosis was 5.3 years. Most patients had gastrointestinal symptoms including diarrhea (54.2%) and abdominal pain (45.8%). Peripheral eosinophilia was present in 91.7% of the patients. Thirteen patients (54.2%) showed anemia, and 15 patients (62.5%) had hypoalbuminemia. EGE was classified as mucosal, subserosal, or muscular in 75.0%, 20.8%, and 4.2% of cases, respectively. Three patients showed gastroduodenal ulcers upon endoscopic analysis. A history of allergy was reported in 13 patients, including atopic dermatitis, allergic rhinitis, and asthma. Five patients (20.8%) improved with food restrictions. Among the 19 patients treated with steroids, 11 (57.9%) discontinued steroid treatment without subsequent relapse, 4 (21.1%) relapsed after ceasing steroid treatment, and 4 (21.1%) showed no response to steroids. Two patients who were resistant to steroids underwent therapeutic surgery. The presence of gastroduodenal ulcers was significantly associated with relapse and steroid resistance. Conclusion: A high suspicion of EGE is warranted when children have nonspecific gastrointestinal symptoms and peripheral eosinophilia. Most patients improved with food restrictions or steroid treatment, although one-third of patients showed a relapse or steroid resistance.

Eosinophilic gastroenteritis, which shows characteristic eosinophilic inflammation, involves any part of the intestine from esophagus to colon. The immunopathogenesis is expected to be associated with IgE-mediated or non-IgE-mediated reaction, but the precise mechanism is not revealed yet. The clinical manifestation is variably dependent on the extent of eosinophilic infiltration. Usually the symptoms, such as abdominal pain, diarrhea, vomiting, wax and wane for a few months result in failure to thrive, which implicates the importance of early detection. Although the diagnosis is made through clinical and histopathologic evidences, we should suspect the illness in a case of anemia, hypoalbuminemia, and peripheral eosinophilia. Recently, we experienced a case of non-IgE-mediated eosinophilic colitis in a 11-year-old male who complained of diarrhea, right lower abdominal pain, body weight loss, was diagnosed with peculiar histopathologic finding of sigmoid colon specimens obtained by sigmoidoscopy.

Herein, the case of a 5-year-old boy with cytomegalovirus-induced Menetrier's disease, with peripheral eosinophilia, presenting with abdominal pain and vomiting, followed by generalized edema, is reported. The initial laboratory findings, hypoalbuminemia and peripheral eosinophilia were noted, with no evidence of renal, hepatic, cardiac or allergic diseases. Gastrofiberscopy was performed under the suspicion of eosinophilic gastroenteritis with protein losing gastropathy. The gastrofiberscopy showed the characteristic features of giant hypertrophy of the gastric rugae, with large quantities of adherent gelatinous material on the gastric fundus and body. The histological findings revealed foveolar hyperplasia, compatible with Menetrier's disease, with massive eosinophilic infiltrations. The presence of cytomegalovirus infection was identified by serology and confirmed by urine PCR. His symptoms, gastrofiberscopic findings and peripheral eosinophilia resolved spontaneously, and he has remained well for 10 months.
