Gastrointestinal Disorders Clinical Trial
Official title:
A Pilot Study Barrier Function, Intestinal Permeability and Tight Junction Expression in Gluten Sensitive Patients With Functional Gastrointestinal Disorders
The overall hypothesis of this research study is that gluten intake alters intestinal barrier function in patients with Irritable Bowel Syndrome (IBS) diarrhea who also exhibit non-celiac gluten sensitivity (NCGS).
The specific aim of this hypothesis-generating, pilot study is to randomize (like the flip of a coin) patients who have Non Celiac Gluten Sensitivity to a 4-week Gluten-containing diet (GCD) or to a Gluten free diet (GFD). The study will evaluate small bowel (SB) permeability functionally (2-sugar differential excretion), morphologically, using probe-based confocal laser to evaluate the small intestinal, as well as molecularly, using tight junction (TJ) messenger RNA (mRNA) expression in small bowel mucosa in response to the different diets. ;
