Parasitic infections make it difficult to establish a diagnosis of primary eosinophilic gastrointestinal disorders (EGID), may even co-occur with inflammatory bowel disease and complicate the management of patients treated with immunosuppressants. Yet, pinworm infection is often ignored as a cause of mucosal eosinophilia. We described 3 cases where pinworm infection was initially misdiagnosed as primary EGID. No current guideline is available for EGID in adult patients, while for patients with inflammatory bowel disease, parasitic infection screening is recommended only in some subset of patients. A more comprehensive and precise recommendation regarding the parasitic species to consider and the diagnostic tests to order is currently lacking.

Abstract
Parasitic infections make it difficult to establish a diagnosis of primary eosinophilic gastrointestinal disorders (EGID), may even co-occur with inflammatory bowel disease and complicate the management of patients treated with immunosuppressants. Yet, pinworm infection is often ignored as a cause of mucosal eosinophilia. We described 3 cases where pinworm infection was initially misdiagnosed as primary EGID. No current guideline is available for EGID in adult patients, while for patients with inflammatory bowel disease, parasitic infection screening is recommended only in some subset of patients. A more comprehensive and precise recommendation regarding the parasitic species to consider and the diagnostic tests to order is currently lacking.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
