Eosinophilic gastroenteritis (EGE) is a rare gastrointestinal disorder. This case highlights EGE presenting with eosinophilic ascites, successfully treated with corticosteroids and dietary changes.
Area of Science:
- Gastroenterology
- Immunology
- Allergy
Background:
- Eosinophilic gastroenteritis (EGE) is a rare condition characterized by eosinophilic infiltration of the gastrointestinal tract.
- Clinical presentation varies based on location and depth of infiltration.
- Eosinophilic ascites is an uncommon manifestation of EGE.
Observation:
- A 41-year-old woman with atopy presented with severe abdominal pain and diarrhea.
- Investigations revealed eosinophil-rich ascites, elevated peripheral eosinophil count, and immunoglobulin E levels.
- Bone marrow, vasculitic, and parasitic evaluations were negative for other causes.
Findings:
- Gastrointestinal biopsies confirmed EGE with eosinophilic ascites.
- The patient showed a significant response to systemic corticosteroids and dietary allergen elimination.
Implications:
- This case underscores the diverse presentations of EGE, including eosinophilic ascites.
- Highlights the importance of considering EGE in patients with unexplained ascites and eosinophilia.
- Emphasizes the efficacy of corticosteroids and dietary interventions in managing EGE.
