The purpose of this clinical study is to learn more about celiac disease pathogenesis and clinical symptoms. In particular, this study will examine the interactions between biological factors such as, intestinal epithelial cells, microbiota, immune system, genetics, and gluten and their effect on celiac disease clinical symptoms, and severity of tissue destruction and its ability to heal in individuals with celiac disease. Information collected in the study will help researchers to generate better resources to advance celiac disease patient care.
Celiac disease is an autoimmune enteropathy characterized by chronic inflammation of the small intestinal mucosa triggered by gluten uptake that occurs in genetically susceptible individuals carrying the specific class II human leucocyte antigens (HLA) DQ2 and DQ8 alleles. There is a spectrum in intestinal tissue damage associated with celiac disease. Some individuals develop inflammatory immunity in the absence of tissue damage, while others experience tissue damage ranging from partial to total villous atrophy. Persistent mucosal damage is associated with several severe complications, including lymphoproliferative malignancy and bone diseases. In addition, individuals with active celiac disease display a wide range of clinical symptoms, including metabolic defects that are not correlated to the degree of villous atrophy. Although much progress has been made in understanding celiac disease, major gaps remain in understanding biological mechanisms underlying inter-individual differences in clinical presentations and capacity to heal while maintaining a gluten-free diet.

RECRUITINGGluten challenge group: quantitative analysis of intestinal villus to crypt ratios
villus to crypt ratios will be quantified on small bowel biopsy samples for the histologic quantification of intestinal responses to disease processes.
Time frame: baseline - 6 weeks
Gluten de-challenge group: quantitative analysis of intestinal villus to crypt ratios
Villus to crypt ratios will be quantified on small bowel biopsy samples for the histologic quantification of intestinal responses to disease processes.
