Gluten Contributes to Irritable Bowel Syndrome Even in Non-Celiacs
Diana received her B.A. in Biochemistry from the University of Pennsylvania, and then a Ph.D. in Cell Biology and Genetics from Cornell. Now she is a freelance science writer and editor in White Plains, New York. Her son was diagnosed with celiac disease in 2006, at the age of five, and she has been keeping her family healthy by feeding them gluten free treats ever since.
Like those with IBS, patients with gluten sensitivity lack the antibodies against tissue transglutaminase that are the hallmark of celiac disease but nonetheless suffer immune mediated inflammation in their gut. Interestingly, when IBS patients without celiac eliminated gluten from their diet, 68% of them reported more severe pain, bloating, and tiredness upon gluten rechallenge. But how – by what mechanism? No changes were detected in intestinal permeability or fecal lactoferrin, a marker of intestinal inflammation. However, it is possible that these phenomena persisted, just at below the level of detection.
Based on these data, and other evidence that is rapidly accruing suggesting that gluten can negatively affect those without celiac disease, Dr. Verdu suggests that IBS patients might be screened for anti-gliadin antibodies even if they lack antibodies against tissue transglutaminase. These nonspecific antibodies can indicate an immunological response to gluten, and thus their presence could used to determine if their symptoms might be alleviated by adherence to a gluten free diet. She makes sure to point out, though, that this is probably not the case for all IBS patients.
