Abstract
INTRODUCTION Eosinophilic gastrointestinal disorders beyond eosinophilic esophagitis (non-EoE EGIDs) are rare chronic inflammatory disorders of the gastrointestinal (GI) tract. Diagnosis is based on clinical symptoms and histologic findings of eosinophilic inflammation after exclusion of a secondary cause or systemic disease. Currently, no guidelines exist for the evaluation of non-EoE EGIDs. Therefore, the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) formed a task force group to provide consensus guidelines for childhood non-EoE EGIDs. METHODS The working group was composed of pediatric gastroenterologists, adult gastroenterologists, allergists/immunologists, and pathologists. An extensive electronic literature search of the MEDLINE, EMBASE, and Cochrane databases was conducted up to February 2022. General methodology was used in the formulation of recommendations according to the Appraisal of Guidelines for Research and Evaluation (AGREE) II and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to meet current standards of evidence assessment. RESULTS The guidelines provide information on the current concept of non-EoE EGIDs, disease pathogenesis, epidemiology, clinical manifestations, diagnostic and disease surveillance procedures, and current treatment options. Thirty-four statements based on available evidence and 41 recommendations based on expert opinion and best clinical practices were developed. CONCLUSION Non-EoE EGIDs literature is limited in scope and depth, making clear recommendations difficult. These consensus-based clinical practice guidelines are intended to assist clinicians caring for children affected by non-EoE EGIDs and to facilitate high-quality randomized controlled trials of various treatment modalities using standardized, uniform disease definitions.

Causes of eosinophilic ascites – A systematic review. ROMANIAN JOURNAL OF INTERNAL MEDICINE 2019; 57:110-124. [DOI: 10.2478/rjim-2018-0041] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2018] [Indexed: 12/17/2022] Open
Abstract
Abstract
Background
. In the last years an uprising interest for a relatively unknown entity, eosinophilic ascites (EA), has been recorded.
Our aim is to investigate the potential causes of EA development, as well as clinical, laboratory, endoscopic and radiologic features, management and outcome in these patients.
Methods
. The following research was performed on PubMed (MEDLINE) database using the medical subject headings [Mesh] terms “Ascites” AND “Eosinophils”.
Results
. A total of 284 results, dating from 1962 onwards, were found and abstracts were examined. 131 papers were excluded and the remaining 153 publications, consisting in case reports and series of cases, were analyzed.
From 171 patients with EA, 127 subjects (74%) had EGE, 17 (10%) parasitic and fungal infections, 11(7%) Hypereosinophilic syndrome and 16 patients (9%) less common diseases (eosinophilic pancreatitis, chronic eosinophilic leukemia, myelofibrosis, T-cell lymphoma, Churg Strauss Syndrome, Systemic lupus erythematosus, Familial paroxysmal polyserositis and Ménétrier’s disease). High eosinophil blood count and IgE levels as well as gastrointestinal symptoms are frequent. The diagnosis is based on ascitic fluid analysis, imaging and endoscopic biopsies. Therapy with corticosteroids results in resolution of eosinophilic ascites in almost all patients.
Conclusion
. In most cases, in the absence of allergy, parasitic infections, malignancy, hematological disorders, peritoneal tuberculosis, inflammatory bowel disease or autoimmune disease, EA develops as a manifestation of eosinophilic gastroenteritis.

Abstract
Eosinophilic gastrointestinal disorders are a series of diseases that include eosinophilic esophagitis, eosinophilic gastritis, eosinophilic gastroenteritis, eosinophilic enteritis, and eosinophilic colitis. Among these disorders, eosinophilic gastroenteritis is an uncommon and heterogeneous disease characterized by eosinophilic infiltration of the gastrointestinal tract in the absence of secondary causes, presenting with a variety of gastrointestinal manifestations. Up to now, epidemiology and pathophysiology of eosinophilic gastroenteritis are still unclear. Based on clinical manifestations and depth of eosinophilic infiltration into the gastrointestinal tract wall, eosinophilic gastroenteritis is classified into three different patterns including predominantly mucosal pattern, predominantly muscular pattern, and predominantly serosal pattern. For diagnosing eosinophilic gastroenteritis, it is necessary for clinicians to have a high degree of clinical suspicion. In addition to the gastrointestinal symptoms, other evidences such as laboratory results, radiological findings and endoscopy can also provide important diagnostic evidences for eosinophilic gastroenteritis. And these indirect pieces of information together with histological results will lead to a definitive diagnosis of eosinophilic gastroenteritis. To avoid specific allergen, dietary treatments can be considered as initial treatment strategy before drug treatment. Corticosteroids are the main medication for eosinophilic gastroenteritis and have a dramatic therapeutic efficacy. Yet other medications need to further verify their effects in clinical practice, and surgery should be avoided as far as possible.

Abstract
BACKGROUND Although there is an increasing number of eosinophilic gastrointestinal disorders (EGID) cases including eosinophilic esophagitis (EoE) and eosinophilic gastroenteritis (EGE), being reported globally, no systematic reviews have been conducted to elucidate the racial differences in these disorders. We aimed to show the racial differences, especially among Caucasians and Asians, in the risk of EoE and EGE. METHODS We conducted a systematic review using PubMed in September 2012. All case reports and case series on EGID that involved human subjects and described race or ethnicity, as well as pathological findings, were included. For the comparison of reported cases between Caucasians and Asians, a chi-squared test was used. RESULTS Among the 687 studies found in PubMed, 121 studies fulfilled the eligibility criteria. In total, 2621 patients were reviewed. Among Caucasian EGID patients, 94% had EoE; while among Asian EGID patients, 72% had EGE (p < 0.001). Among EoE, Asians were significantly less likely to have dysphagia and heartburn, but more likely to have vomit and abdominal pain, compared to Caucasians (p < 0.001). Further, among EGE, Asians were significantly more likely to have eosinophil-infiltrated colon than Caucasians (OR: 3.22, 95% confidence interval [CI]: 1.60-7.04), but were less likely to have eosinophil-infiltrated stomach (OR: 0.29, 95% CI: 0.17-0.49). CONCLUSIONS We found that EoE occurs more frequently in Caucasian EGID patients than Asian EGID patients, while the reverse is true for EGE. Also, racial disparities in symptoms and eosinophil-infiltrated tissues were observed. Our findings suggest further genetic and environmental studies to elucidate the etiology of EGID.

Abstract
BACKGROUND Eosinophilic ascites is the most unusual presentation of eosinophilic gastroenteritis (EGE), caused by edema and eosinophilic inflammation of the small bowel wall's serosal layer. CASE REPORT We report the case of a 37-year-old woman, who presented with diffuse abdominal pain, nausea, abdominal distension, moderate ascites and diarrhea of two weeks duration. The rest of physical and clinical examination was unremarkable, and her past medical history was uneventful. Magnetic Resonance Imaging showed the presence of ascites and diffuse thickening of small bowel wall, but did not detect a primary malignancy in the abdominal cavity; and no signs of portal hypertension or liver damage. Laboratory test results revealed essential peripheral blood eosinophilia, elevated serum IgE and marked increase of eosinophils in the abdominal fluid. Treatment with corticosteroids normalized laboratory tests results, and the ascites resolved immediately. CONCLUSIONS EGE is a rare entity and it should be kept in mind in patients of unexplained ascites. The absence of primary malignancy on imaging, coupled with marked increase of fluid esinophilia and immediate response to treatment with steroids, confirm indirectly the diagnosis of EGE. Hippokratia 2014; 18 (3): 275-277.

Abstract
We report a case of a 49-year-old male patient with abdominal distension and diffuse stomach cramps associated with peripheral eosinophilia. Treatment for eosinophilic parasitosis was not effective. After a few weeks, the patient developed acute obstructive abdomen with ascites, which was atypically improved with the use of antispasmodics and analgesics. Upper digestive endoscopy, colonoscopy and histopathologic examination of the gastric and intestinal mucosa did not show any significant changes. Video laparoscopic biopsy of the mesenteric lymph node and peritoneum revealed a nonspecific chronic inflammatory process with intense diffuse tissue eosinophilia. Complementary tests revealed right-sided pleural effusion and increased serum immunoglobulin E levels, with altered D-xylose absorption test results. The patient was treated with a hypoallergenic diet and an oral corticosteroid; the symptoms resolved and the laboratory test results improved. Eosinophilic gastroenteritis is a rare inflammatory disease characterized by eosinophilic infiltration in the wall of the gastrointestinal tract. The clinical presentation varies according to the affected site and the depth and extent of digestive tract involvement. This case report, which presents the rare simultaneous involvement of the mucosal, muscular and serosal layers, aims to describe and discuss the clinical and therapeutic aspects of eosinophilic gastroenteritis as well as its progression.

Abstract
We report a case of a healthy young man presenting with 1-week history of diarrhoea, acute abdominal pain and weight loss. Laboratory investigation showed very high peripheral eosinophils levels. After exclusion of the other causes of eosinophilia, a histological bowel sample analysis revealed marked eosinophilic infiltration of a small bowel mucosal layer which confirmed the suspicion of eosinophilic enteritis. Unlike most of the described cases, this patient did not require any specific treatment. Eosinophilic gastroenteritis is a rare and heterogeneous disease that is probably underdiagnosed in clinical practice because it requires a high degree of suspicion and an endoscopic biopsy for definite diagnosis.

Abstract
Background: There is a broad etiology for effusion eosinophilia that includes allergic, reactive, infectious, immune, neoplastic, and idiopathic causes. We report and describe the cytomorphologic findings of a rare case of eosinophilic ascites due to severe eosinophilic ileitis. Case Presentation: A 17-year-old male manifested acutely with eosinophilic ascites due to severe biopsy-proven subserosal eosinophilic ileitis. Isolated peritoneal fluid submitted for cytologic evaluation revealed that 65% eosinophils were present in a bloody background. The patient responded to corticosteroids, with complete resolution of his ascites. Conclusion: Eosinophilic gastroenteritis with subserosal involvement should be added to the list of causes for eosinophils in peritoneal fluid. The finding of eosinophilic ascites, with appropriate clinical and laboratory findings, may warrant the need to perform laparoscopic intestinal biopsies to confirm the diagnosis.

Abstract
Eosinophilic gastroenteritis is a clinicopathological disease affecting both children and adults that is characterized by patchy or diffuse eosinophilic infiltration of the gastrointestinal tract with variable resultant clinical gastrointestinal manifestations. The eosinophil, eotaxin, and Th-2 cytokines are important in pathogenesis of this disease entity. It may be confused with parasitic and bacterial infections (including Helicobacter pylori), inflammatory bowel disease, hypereosinophilic syndrome, myeloproliferative disorders, periarteritis, allergic vasculitis, scleroderma, drug injury, and drug hypersensivity. Obtaining the correct diagnosis is important, and a pathologist usually makes this distinction. Effective treatments include systemic/topical corticosteroids, specific food elimination or an elemental diet, certain drugs, and even surgery. A variety of new therapeutic approaches are now under trial.

Abstract
Eosinophilic gastroenteritis is an infrequently diagnosed condition that is characterized by prominent eosinophilic infiltration of the stomach or small intestine, generally localized to one level of the intestinal wall; the variable organ locus and wall depth produce heterogeneous clinical presentations. A strong association with atopy is present in most cases, supported by circumstantial evidence and the demonstration of Th-2 proinflammatory cytokine profiles in animal studies. A high degree of suspicion is required to establish the diagnosis, which must be based on intense gastrointestinal eosinophilia. Management is directed toward removal of offending allergens and use of anti-inflammatory agents. Novel and emerging treatments on the horizon are biologic therapies and selective anti-eosinophil agents.
