This procedure is typically not uncomfortable and may be done on an outpatient basis. A pathologist will analyze the tissue samples under a high-powered microscope to see the small cell structures.
If eosinophils are present in the sample, the pathologist will count how many are visible. A count of 15 or more eosinophils per high-powered microscopic field is highly suggestive of EoE. A patient may have EoE even if the esophagus looks normal during the endoscopy. The biopsies will help in making an accurate diagnosis. Endoscopy with the biopsies is the only reliable method of diagnosing EoE at this time, although promising research for less invasive diagnostic and monitoring is currently underway.
The two main treatments recommended for EoE are diet management and medication. In some cases, a combination of these therapies may be used.
Diet Management: Diet therapy involves removal of suspected or known food triggers. For some patients, elemental nutrition may be recommended to supplement the diet, or for full nutrition. Elemental diets consist of special amino acid-based formulas that do not elicit an allergic response. Dilation If the esophagus has become too narrow as the result of EoE, it may cause food to become stuck known as a food impaction. An esophageal dilation may be recommended to treat a narrowed esophagus.
Visits should be every one to three months after diagnosis. The number of visits will depend on how severe the disease is. Once on a treatment plan, follow-up visits may be every six months to one year.
These visits will focus on answering your questions and how well treatment is working. This includes symptoms and response to medications. The doctor will check your child's weight and overall nutrition. At each visit, discuss how well diet therapy is working.
If symptoms have been better for six months to a year, you or your child may be ready for a food trial. Ask if it is time to add restricted food back into the diet, or to change elemental formulas. A gastroenterologist or allergist can work with you to help make these decisions. Review the medicines you or your child are taking with the allergist. PPIs are used for four to eight weeks. They can be stopped when you or your child feel better but may be needed in the future if symptoms come back.
Corticosteroids can also be decreased and stopped when symptoms improve and resolve. You can also work with your doctor to decide if another endoscopy is needed. If there are problems with swallowing or food impactions, follow-up scopes may be needed for ongoing monitoring and treatment.
An EoE diagnosis can be overwhelming. Medical and dietary treatment alone are not enough to help you deal with the stress of managing EoE. References 1.

Mayo Clinic. June 24, Alexander JA expert opinion. An atopic person is someone who has symptoms of one or more allergic disorders.
These include asthma, allergic rhinitis, atopic dermatitis eczema and food allergy. EoE has occasionally been shown to occur in other family members. Because many patients with EoE are atopic, they may be seen first by an allergist who suspects the diagnosis and refers them to a gastroenterologist for confirmation of EoE.
Alternatively, if the diagnosis of EoE is made by a gastroenterologist, you may be referred to an allergist for allergy testing. It will provide you, your family and the gastroenterologist with information so that any allergic aspects of EoE can be properly treated. It may also help plan diet therapy and eventual reintroduction of foods to your diet. Eosinophilic Esophagitis: Environmental Allergies Environmental allergies to substances such as pollens, animals, dust mites and molds possibly play a role in EoE.
For some patients, it may seem like their EoE is worse during pollen seasons. Allergy testing for these common environmental allergies is often part of the EoE evaluation. Eosinophilic Esophagitis: Food Allergies Adverse immune responses to food are the main cause of EoE in a large number of patients. Allergists are experts in evaluating and treating EoE related to food allergies.
However, the relationship between food allergy and EoE is complex. In classical Immunoglobulin E IgE -mediated food allergy, the triggers are easily diagnosed by a history of a severe allergic reaction such as hives and vomiting within minutes after ingestion of the offending food. In EoE, it is more difficult to establish the role of foods because the reactions are delayed, and can develop over days, making it harder to pinpoint a specific food as the trigger.
Allergists may perform different allergy tests to identify sensitization to foods that might play a role in causing EoE. Foods such as dairy products, egg, soy and wheat are recognized as the most common triggers for EoE. However, conventional allergy tests often fail to detect sensitivity to the foods causing EoE. This is because most food allergy reactions in EoE are delayed and caused primarily by immune mechanisms other than classical IgE-mediated food allergy.
A person with EoE may have one or more foods triggering their EoE. Thus, removal of suspected food s from the diet followed by a decrease in symptoms and esophageal inflammation is necessary to prove that the food s is are causing EoE. Eosinophilic Esophagitis: Prick Skin Testing People who have allergies react to a particular substance in the environment or their diet. Any substance that can trigger an allergic reaction is called an allergen.
Prick skin testing involves using a prick device to introduce a small amount of allergen into the skin by making a small puncture. Most food extracts used in allergy testing are purchased by the allergist from commercial companies who specialize in making them.
