High Discovery Rate of Duodenal and Gastric Eosinophilia in Patients With Unexplained Moderate–Severe Abdominal Symptoms: A Prospective US Multisite Study

This is the authors' abstract. We don't add key points for this paper.

Eosinophilic gastrointestinal (GI) diseases, including eosinophilic gastritis (EoG) and eosinophilic duodenitis (EoD), are chronic inflammatory conditions characterized by GI tissue eosinophilia and persistent, often debilitating, GI symptoms.1 Although considered rare, emerging evidence suggests that the prevalence of eosinophilic GI diseases is increasing in the United States, and may be more prevalent than previously thought.1,2 Notably, diagnosis requires an adequate biopsy protocol, as disease is often patchy,3 and the diagnosis may be overlooked if eosinophils are not counted.
