False-positive gliadin and endomysium antibodies and exocrine pancreatic insufficiency as pitfalls in the differential diagnosis of duodenal Crohn's versus celiac disease.
We report a 13-yr-old boy with Crohn's disease in the upper gastrointestinal tract presenting with abdominal pain, failure to thrive, recurrent fever, iron-deficient anemia, and exocrine pancreatic insufficiency. Initially, latent celiac disease was suggested because of normal endoscopic findings, the finding of non-specific inflammation on histological evaluation of duodenal biopsies, positive IgA and IgG gliadin, as well as endomysium antibodies and exocrine pancreatic insufficiency. There was no response to a gluten-free diet. A reevaluation revealed Crohn's disease.
