Eosinophilic gastroduodenitis: a pediatric perspective.

Abstract

Eosinophilic gastroduodenitis (EoGD) is a group of chronic inflammatory disorders characterized by an increased presence of eosinophils in the stomach and duodenum. Although relatively rare, it is an increasingly recognized form of eosinophilic gastrointestinal diseases (EGIDs) with significant clinical implications, particularly in pediatric patients. Despite advancements in diagnostic tools, considerable delays in diagnosis persist due to the nonspecific nature of clinical manifestations, which often resemble more common gastrointestinal disorders. Early referral to a gastroenterologist is critical, especially when patients present with persistent gastrointestinal signs and symptoms that do not improve with treatment for common conditions like irritable bowel syndrome. Food allergens and microbiota may play a role in the pathogenesis of this disease. Management typically involves a combination of dietary modifications, pharmacological treatments such as corticosteroids, and, in some cases, biologic agents targeting eosinophilic inflammation. However, long-term outcomes remain variable, and data on prognosis are still limited, underscoring the need for further research. Future studies should focus on validating new diagnostic markers and therapeutic strategies, better understanding long-term outcomes, and developing personalized treatment plans. A multidisciplinary approach, incorporating the expertise of gastroenterologists, allergists, dietitians, and surgeons, is crucial to ensure optimal patient care and management.
