New clinical issues in celiac disease

Celiac disease is a chronic disorder of gluten sensitivity associated with a spectrum of mucosal lesions termed preinfiltrative, infiltrative, hyperplastic, destructive, and atrophic. The symptoms are not related to the degree of mucosal pathology but to the extent of the mucosal lesion. Neoplasms constitute the major complication of celiac disease, and EATCL is the most common neoplasm in this category. There is evidence that a strict gluten-free diet is protective against the complications of celiac disease; hence it is important that even the subclinical forms be diagnosed early. Small bowel biopsy remains the gold standard for diagnosis of celiac disease; however, antibody tests are a useful adjunct in deciding whom to biopsy and for screening groups at high risk before initiating a lifelong gluten-free diet.
