Increased Rectal Nitric Oxide in Coeliac Disease after Local Challenge with Gluten

Pages 169-173 | Published online: 08 Jul 2009
 

Abstract

Background: Coeliac disease is an inflammatory disorder characterized by reversible atrophy of small intestinal villi following the ingestion of gluten. Earlier studies indicate that the inflammatory response to gluten may occur also very distally in the gastrointestinal tract. The aim of this study was to evaluate whether rectal challenge with gluten would trigger an increased local production of the gas nitric oxide (NO), a novel marker of intestinal inflammation. Methods: Rectal challenge with partially digested gluten was performed in 20 patients with treated coeliac disease and in 13 healthy controls. Luminal levels of NO were measured in the rectum at 0, 8 and 24 h using a chemiluminescence technique. Results:
