Multiple studies have shown that Helicobacter pylori infection is associated with a lower prevalence of inflammatory bowel disease (IBD).1,2 Besides chronic active gastritis (CAG) resulting from gastric infection with H pylori, pathologists have noticed another form of CAG, which is unrelated to H pylori infection and seems to cluster in patients with IBD.3-5 The aim of the present study was to compare the prevalence of H pylori-negative and H pylori-positive CAG in patients with IBD, and microscopic colitis (MC).

UI MeSH Term Description Entries
D003424 Crohn Disease A chronic transmural inflammation that may involve any part of the DIGESTIVE TRACT from MOUTH to ANUS, mostly found in the ILEUM, the CECUM, and the COLON. In Crohn disease, the inflammation, extending through the intestinal wall from the MUCOSA to the serosa, is characteristically asymmetric and segmental. Epithelioid GRANULOMAS may be seen in some patients.

D005756 Gastritis Inflammation of the GASTRIC MUCOSA, a lesion observed in a number of unrelated disorders. Gastritides

D015212 Inflammatory Bowel Diseases Chronic, non-specific inflammation of the GASTROINTESTINAL TRACT. Etiology may be genetic or environmental. This term includes CROHN DISEASE and ULCERATIVE COLITIS. Bowel Diseases, Inflammatory,Inflammatory Bowel Disease
D016480 Helicobacter pylori A spiral bacterium active as a human gastric pathogen. It is a gram-negative, urease-positive, curved or slightly spiral organism initially isolated in 1982 from patients with lesions of gastritis or peptic ulcers in Western Australia. Helicobacter pylori was originally classified in the genus CAMPYLOBACTER, but RNA sequencing, cellular fatty acid profiles, growth patterns, and other taxonomic characteristics indicate that the micro-organism should be included in the genus HELICOBACTER. It has been officially transferred to Helicobacter gen. nov. (see Int J Syst Bacteriol 1989 Oct;39(4):297-405).

D016481 Helicobacter Infections Infections with organisms of the genus HELICOBACTER, particularly, in humans, HELICOBACTER PYLORI. The clinical manifestations are focused in the stomach, usually the gastric mucosa and antrum, and the upper duodenum. This infection plays a major role in the pathogenesis of type B gastritis and peptic ulcer disease. Infections, Helicobacter,Helicobacter Infection,Infection, Helicobacter
D046728 Colitis, Microscopic A condition characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. This syndrome was first described in 1980 by Read and associates. Subtypes include COLLAGENOUS COLITIS and LYMPHOCYTIC COLITIS. Both have similar clinical symptoms and are distinguishable only by histology. Microscopic Colitis
