Impressions and aspirations from the FDA GREAT VI Workshop on Eosinophilic Gastrointestinal Disorders Beyond Eosinophilic Esophagitis and Perspectives for Progress in the Field. J Allergy Clin Immunol 2022; 149:844-853. [PMID: 34953790 PMCID: PMC8901475 DOI: 10.1016/j.jaci.2021.12.768] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Revised: 12/09/2021] [Accepted: 12/14/2021] [Indexed: 11/25/2022]
Abstract
The US Food and Drug Administration hosted a workshop on July 21, 2021, to discuss the disease characteristics, natural history, and end points to assess treatment benefit in patients with eosinophilic gastrointestinal disorders (EGIDs) beyond eosinophilic esophagitis (EoE). Notably, EGIDs beyond EoE, such as eosinophilic gastritis, eosinophilic enteritis, and eosinophilic colitis, herein referred to as non-EoE EGIDs, are understudied relative to EoE. This workshop provided a forum for open discussion among stakeholders-medical professionals (including their societies and research groups), Food and Drug Administration representatives, an industry representative, and a patient representative-to facilitate drug development. Experts in many disciplines related to EGIDs, including allergy, immunology, epidemiology, gastroenterology, and pathology, and both adult and pediatric clinicians contributed. Herein, we discuss some of the insights of the material presented at the meeting and present perspectives on moving the field forward toward drug approval.

Abstract
Eosinophilic gastroenteritis is a rare disease of unknown etiology. It is characterized by patchy or diffuse eosinophilic infiltration of the bowel wall to a variable depth and various gastrointestinal manifestations. We describe a case of severe eosinophilic gastroenteritis presenting as frequent bowel obstruction and diarrhea in a 35-year-old man. The patient was misdiagnosed and underwent surgery because of intestinal obstruction when he was first admitted to a local hospital. Then he was misdiagnosed as having Crohn’s disease in another university teaching hospital. Finally, the patient asked for further treatment from our hospital because of the on-going clinical trial for treating refractory Crohn’s disease by fecal microbiota transplantation. Physical examination revealed a slight distended abdomen with diffuse tenderness. Laboratory investigation showed the total number of normal leukocytes with neutrophilia as 90.5%, as well as eosinopenia, monocytopenia and lymphocytopenia. Barium radiography and sigmoidoscopy confirmed inflammatory stenosis of the sigmoid colon. We diagnosed the patient as having eosinophilic gastroenteritis by multi-examinations. The patient was treated by fecal microbiota transplantation combined with oral prednisone, and was free from gastrointestinal symptoms at the time when we reported his disease. This case highlights the importance of awareness of manifestations of a rare disease like eosinophilic gastroenteritis.

Abstract
Eosinophilic enteritis is a rare disease of unknown etiology. It is characterized by eosinophilic infiltration of the bowel wall to a variable depth and symptoms associated with gastrointestinal tract depending upon the predominant layer involved. Diagnosis of eosinophilic enteritis requires a high index of suspicion and exclusion of various disorders that are associated with peripheral eosinophilia. We report a case of unusual presentation of eosinophilic enteritis clinically presenting as intestinal obstruction due to multiple strictures of the small bowel in an adult male.

Abstract
Eosinophilic gastroenteritis (EG) is characterized by eosinophilic infiltration of the bowel wall and variable gastrointestinal manifestations. Clinicians should have a high index of suspicion for EG when faced with gastrointestinal symptoms and peripheral eosinophilia to avoid incorrect diagnosis and inappropriate treatments. A 24-year-old woman was admitted to our hospital complaining of acute right lower quadrant abdominal pain and a laparoscopic appendectomy performed for a presumed diagnosis of an acute appendicitis. However, the procedure revealed bowel edema and a moderate amount of ascites without evidence of a suppurative appendicitis. Postoperatively, she showed persistent and progressive eosinophilia, exudative eosinophilic ascites, eosinophilic infiltration of the resected appendix wall, and eosinophilic infiltration of gastroduodenal mucosa. A punch biopsy of the abdominal skin also revealed inflammation with marked eosinophilic infiltration of the skin. She recovered after the treatment with a low dose of steroid for the EG with eosinophilic dermatitis. EG with eosinophilic dermatitis has not been reported yet and is considered fortuitous in this case.

Abstract
Eosinophilic gastroenteritis is a rare disease of unknown etiology. It is characterized by eosinophilic infiltration of the bowel wall to a variable depth and symptoms associated with gastrointestinal tract. Recently, the authors experienced a case of eosinophilic gastroenteritis presenting as small bowel obstruction. A 51-year old woman was admitted to our hospital complaining of abdominal pain and vomiting. Physical examination revealed a distended abdomen with diffuse tenderness. Complete blood count showed mild leukocytosis without eosinophilia. Computed tomography confirmed a dilatation of the small intestine with ascites. An emergency laparotomy was performed for a diagnosis of peritonitis due to intestinal obstruction. Segmental resection of the ileum and end to end anastomosis were performed. Histologically, there was a dense infiltration of eosinophils throughout the entire thickness of ileal wall and eosinophilic enteritis was diagnosed. The patient recovered well, and was free from gastrointestinal symptoms at the time when we reported her disease.

Abstract
Eosinophilic gastroenteritis is a rare gastrointestinal disorder with eosinophilic infiltration of the gastrointestinal wall and various gastrointestinal dysfunctions. Diagnosis requires a high index of suspicion and exclusion of various disorders that are associated with peripheral eosinophilia. We report a case of eosinophilic gastroenteritis, which had features of the predominant subserosal type presenting with ascites and hepatic dysfunction, and which responded to a course of low-dose steroid.

Abstract
Adverse reactions to food that result in gastrointestinal symptoms are common in the general population; while only a minority of such individuals will have symptoms due to immunologic reactions to foods, gastrointestinal food allergies do exist in both children and adults. These immune reactions are mediated by immunoglobulin E-dependent and -independent mechanisms involving mast cells, eosinophils, and other immune cells, but the complexity of the underlying mechanisms of pathogenesis have yet to be fully defined. Knowledge of the spectrum of adverse reactions to foods that affect the digestive system, including gastrointestinal food allergy, is essential to correctly diagnose and manage the subset of patients with immunologically mediated adverse reactions to foods. Potentially fatal reactions to food necessitate careful instruction and monitoring on the part of health care workers involved in the care of individuals at risk of anaphylaxis. New methods of diagnosis and novel strategies for treatment, including immunologic modulation and the development of hypoallergenic foods, are exciting developments in the field of food allergy.

Abstract
Eosinophilic cystitis is an uncommon disease in children, and its association with chronic granulomatous disease (CGD) has been previously reported in only five patients. In all those patients the disease showed either a self-limited benign course or a rapid response to corticosteroid treatment. The authors describe a child with X-linked CGD who developed eosinophilic cystitis with a recurrent course and difficult therapeutic management. The authors also discuss the pathogenesis of granuloma formation in CGD and review the literature for current therapies for these complications.

Abstract
Eosinophilic esophagitis (EE) is an important esophageal disorder with distinct clinicopathologic features, and the condition is associated with a high prevalence of food allergies and atopy. In the past decade, we have improved our ability to recognize the phenotype of EE, but our ability to treat EE effectively remains limited despite several reports of successful treatment using elemental or elimination diets, and systemic and topical corticosteroids. The limitations for developing effective treatment regimens are due to some still unresolved and ambiguous aspects of the pathogenesis of EE. Neither the predisposing factors for developing EE in a subset of patients with atopy, nor the variable responsiveness to control measures for allergens are fully understood. There also remain questions about the precise role of gastroesophageal reflux, and the natural history of the disorder, contingent on which is the optimal treatment of EE. In devising treatment for a patient with EE, all attempts should be made to identify and control food and other allergies. In patients who have no diagnosed allergies or who are unresponsive to allergy treatment, topical steroids are a safe and effective treatment option. Systemic steroids should be reserved for those patients who are refractory to topical steroids. Beyond the initial phase of induction treatment, it is crucial to develop effective and safe maintenance treatment regimens based on ongoing allergen control and mast cell inhibitors. There are limited but encouraging data to support further exploration of the role of leukotriene and interleukin-5 inhibitors as safe, effective, and steroid-sparing treatment options.
