Abstract
Celiac disease is a complex autoimmune enteropathy that affects the small bowel in genetically predisposed individuals. It is thought that celiac disease is the result of an inappropriate T cell-mediated immune response against ingested gluten protein. The characteristic lesion of the small intestinal mucosa includes loss of absorptive villi and infiltration of the lamina propria with inflammatory cells. The clinical presentation of celiac disease varies greatly depending on patient's age, duration and extent of the disease, and the presence of extraintestinal manifestations. Unfortunately, most patients with celiac disease have either silent or atypical presentations, thus escaping diagnosis for several years. Medical nutrition therapy with lifelong adherence to a strict gluten-free diet is the only accepted treatment of celiac disease. Individuals at risk for this entity should undergo appropriate serologic testing, but there is no evidence to support mass screening.
