Abstract:
Recurrent aphthous stomatitis is a common disease of the oral mucous membranes. Currently a hypothesis is being discussed that it might be pathogenetically related to coeliac disease. We evaluated the frequency of coeliac disease anti-endomysial (or anti-transglutaminase) antibodies in patients with recurrent aphthous stomatitis. Blood samples from 42 patients were evaluated and 2/42 (4.7%) were IgA- and IgG-endomysial antibody-positive. None of the 42 persons in the control group had antibodies, which was not statistically different from the patient group. The two antibody-positive patients had episodes of mild gastrointestinal symptoms only, but histopathology of duodenal mucous membranes confirmed coeliac disease. All symptoms related to aphthous stomatitis responded well to a gluten-free diet. We conclude that every patient with recurrent aphthous stomatitis should be asked about a history of gastrointestinal complaints and screened for markers of coeliac disease, since recurrent aphthous stomatitis may in some cases respond to a gluten-free diet.

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
