We investigated an antiinflammatory effect of rebamipide [2-(4-chlorobenzoylamino)-3-[2(1H)-quinolinon-4-yl] propionic acid], a gastroprotective agent, in H. pylori-associated gastritis. Eighty-six patients with H. pylori-positive chronic gastritis were enrolled: 53 were treated with rebamipide (300 mg daily for 12 months) and 33 served as controls. Significant decreases in mononuclear cell infiltration into the antrum and corpus were noted in the rebamipide treatment group (before vs after, 1.42 +/- 0.15 vs 1.02 +/- 0.15; P < 0.01 and 1.60 +/- 0.15 vs 1.21 +/- 0.14; P < 0.05, respectively). Levels of infiltrating neutrophil were also decreased in the antrum (before vs after, 0.98 +/- 0.14 vs 0.70 +/- 0.13; P < 0.05) and were associated with a decrease in iNOS production. Sera from patients treated with rebamipide showed a significant decrease in gastrin (276.3 +/- 58.3 pg/ml vs 173.0 +/- 34.2 pg/ml; P < 0.05), whereas no change was observed in the control group. These suggest that long-term rebamipide treatment improved histologic gastritis and decreased serum gastrin levels in H. pylori-associated gastritis.

UI MeSH Term Description Entries
D010435 Pepsinogens Proenzymes secreted by chief cells, mucous neck cells, and pyloric gland cells, which are converted into pepsin in the presence of gastric acid or pepsin itself. (Dorland, 28th ed) In humans there are 2 related pepsinogen systems: PEPSINOGEN A (formerly pepsinogen I or pepsinogen) and PEPSINOGEN C (formerly pepsinogen II or progastricsin). Pepsinogen B is the name of a pepsinogen from pigs. Pepsinogen B

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).
