Patients with type 1 diabetes have been known to be more prone to another autoimmune disorder, celiac disease, in which gluten in wheat, rye and barley triggers an immune response that damages the small intestine or gut. Now there’s evidence that the two diseases have a genetic link: they share at least seven chromosome regions.
The discovery, published in this week's New England Journal of Medicine, indicates that both diseases may be triggered by similar genetic and environmental mechanisms, such as certain foods, that cause patients' immune systems to become overactive and destroy healthy instead of infected tissue. Previous research has found that celiac disease is five to 10 times more common in people with type 1 diabetes than in the general population, an editorial accompanying the study notes.
