 The diagnosis of celiac disease carries with it important ramifications. Celiac disease is a systemic immunologic disorder in which the sentinel lesion is an enteropathy triggered by polypeptides derived primarily from the gliadin proteins found in wheat, rye and barley. Ingestion of the offending proteins leads to inflammation and intestinal mucosal damage, which results in a spectrum of abdominal symptoms, increased intestinal permeability, malabsorption, occult gastrointestinal bleeding and diarrhea. Systemic manifestations of celiac disease include a myriad of conditions including malignancy and autoimmune disease.
