The cause of eosinophilic gastroenteropathy in older children and adults is unknown. In this report, two post-liver transplantation children treated with low-dose cyclosporine A and alternate-day low-dose prednisone are described who were administered a single bolus administration of a lympholytic dose of corticosteroids without taper and who developed intestinal symptomatology several weeks later. Histologic examination of mucosal biopsy specimens from various regions of the gastrointestinal tract showed an intense eosinophilic infiltration of the mucosa and lamina propria. The patients recovered after corticosteroid administration was tapered. Post- transplant gastroenteric eosinophilic inflammation may need to be considered in patients on immunomodulatory medications who have chronic intestinal symptomatology.
