Summary
Eosinophilic esophagitis, a condition often misdiagnosed, can be effectively managed with an exclusion diet. This case highlights the importance of specific diagnostic tests for food allergies in patients with persistent gastroesophageal symptoms.
Area of Science:
- Gastroenterology
- Allergology
- Immunology
Background:
- Esophagitis is a growing concern, particularly in patients with refractory gastroesophageal reflux, dysphagia, vomiting, or abdominal pain.
- A 37-year-old male presented with a decade-long history of reflux and dysphagia, alongside intermittent diarrhea and alcohol-induced epigastric pain.
Observation:
- Standard allergy tests, including skin prick tests for common allergens, were negative.
- Prick-prick tests using natural foods yielded positive results for egg white, while specific IgE and in vitro tests (histamine release and basophil activation) were positive for egg white and yolk.
Findings:
- The patient was diagnosed with eosinophilic esophagitis.
- Commercial food extracts showed variability, potentially leading to false-negative skin prick tests.
- Prick-prick testing with natural foods proved more sensitive than standard prick tests for diagnosing food allergies.
Implications:
- In vitro diagnostic techniques beyond specific IgE are valuable for food allergy diagnosis.
- An exclusion diet targeting implicated foods (egg white and yolk) was more effective for symptom remission than other treatments.
- This case underscores the diagnostic utility of prick-prick tests and exclusion diets in eosinophilic esophagitis.
