Overview
Historical Perspective
Classification
Pathophysiology
Causes
The causes of EoE are the food and pollen react with the lining of the esophagus, these allergens cause the multiplication of eosinophils in the layers of the esophagus and produce a protein that causes inflammation. The inflammation further cause scarring, excessive fibrous tissue deposition over the lining of the esophagus eventually leading to dysphagia. The dysphagia can sometimes worsen to cause food impaction and additional symptoms such as chest pain.
Differentiating Eosinophilic esophagitis overview from Other Diseases
Eosinophilic esophagitis must be differentiated from other diseases that cause dysphagia such as reflux esophagitis, esophageal carcinoma, systemic sclerosis, esophageal spasm, pseudoachalasia, stroke, esophageal candidiasis and [[chagas d
Epidemiology and Demographics
Risk Factors
The risk factors of EoE are as follows bimodal age distribution common in both children and adults, male gender, cold and dry climate, EoE is common in people with a history of European ancestry, summer and fall, positive family history of EoE, history of allergies such as asthma, industrial exposures, environmental allergies, chronic respiratory disease, food allergies and atopic dermatitis.

Diagnosis
Diagnostic Criteria
History and Symptoms
The history and symptoms of eosinophilic esophagitis (EoE), dysphagia, regurgitation, cough, chest pain, food impaction, upper abdominal pain, vomiting. Clinical features in children are follows abdominal pain, nausea, emesis, failure to thrive. Clinical features in the adolescents and adults are as follows dysphagia, heartburn, food impaction, strictures.
Physical Examination
The physical examination of the patients with EoE is usually normal.
Laboratory Findings
Imaging Findings
The barium swallow of the esophagus shows multiple rings associated with eosinophilic esophagitis, There are no MRI nor CT scan findings associated with EoE. however, an MRI or a CT scan may be helpful in the diagnosis of complications of EoE such as tears, perforation strictures etc
Other Diagnostic Studies
Treatment
Medical Therapy
The optimal treatment of eosinophilic esophagitis remains uncertain. An eight-week course of therapy with topical corticosteroids (fluticasone or budesonide) may be used as the first-line pharmacologic therapy. Allergen elimination usually leads to improvement in dysphagia and reduction of eosinophil infiltration. Esophageal dilation of is generally reserved for refractory cases with esophageal stricture.
