Gastrointestinal Eosinophilic Diseases Program (GEDP) - Clinical Services

The Gastrointestinal Eosinophilic Diseases Program (GEDP) at Children's Hospital Colorado​ provides state-of-the-art, multidisciplinary care to patients affected by eosinophilic gastrointestinal diseases (EGIDs), including eosinophilic esophagitis (EoE).

EGIDs are a group of diseases characterized by a wide variety of gastrointestinal symptoms including vomiting, swallowing problems, food impaction, abdominal pain, diarrhea, slow growth, and bleeding. These symptoms occur in combination with increased numbers of eosinophils in the gastrointestinal lining. Eosinophils are a type of white blood cell that has been primarily associated with allergic diseases but are also found in other diseases.

Depending on the part of the gastrointestinal tract affected, EGIDs can be called a variety of different names, such as eosinophilic esophagitis (EoE), eosinophilic gastritis (EG), eosinophilic gastroenteritis (EGE), and eosinophilic colitis (EC), with the diagnostic term being based primarily on the location of the mucosal eosinophilia.

EGID Classifications

Physicians classify the disease according to the body tissue where the eosinophils accumulate. Each type of the disease requires long-term treatment. There is no cure for EGID.

  • Eosinophilic esophagitis (EoE) is the most common type of EGID, where there are large numbers of eosinophils found in the esophagus. The esophagus is the tube that carries food from the mouth to the stomach.
  • Eosinophilic gastroenteritis (EG) and eosinophilic enteritis (EE) affects the stomach and/or the small intestine.
  • Eosinophilic colitis (EC) is the rarest form of the disease and describes the occurrence of high levels of eosinophils in the large intestine.

EGID can affect people of all ages and ethnic backgrounds, although there appear to be sex and genetic factors associated with the disease. Research has found that 75% of individuals with EoE are male and 70-80% have associated allergic disorders such as asthma, eczema, and seasonal and/or food allergies.

Patients and families are provided with the latest in clinical services ranging from endoscopic assessment, allergy testing, and in some circumstances, novel treatment protocols. Importantly, a wide range of clinical research projects are being conducted to uncover new knowledge and improve patient care. Interested patients are offered the opportunity to participate in any protocol.
