Publikováno v: American Journal of Gastroenterology. 93:1090-1096

Objective: Gastric cancer (GC) and adenoma (GA) are reported to be related to atrophic gastritis, in which the serum pepsinogen (PG) I level and the PGI/PGII ratio (I/II ratio) are reduced. To verify that the finding of a low PG level increases the r

Gastric Carcinoma and Helicobacter pylori Infection: Role of Nitric Oxide and Inflammatory Cytokines in Gastric Carcinogenesis

Autor: Shinji Tanaka, Kunihiko Komoto, Toyoko Goto, Kazuaki Chayama, Ken Haruma, Koji Sumii, Yasuhiko Kitadai, Masaharu Yoshihara

Recent studies have shown that Helicobacter pylori infection is etiologically and experimentally associated with gastric carcinoma. However, the role of H. pylori in carcinogenesis has not been clarified. H. pylori infection leads to sustained produc

Autor: Ken Haruma, Goro Kajiyama, Xing Chen, Masaharu Yoshihara, Koji Sumii, Mitsuhiro Mihara, Tomoari Kamada, Kunihiko Komoto

Publikováno v: Helicobacter. 5(2)

Background. The 13C urea breath test (UBT) is considered to be the most accurate way of diagnosing Helicobacter pylori infection. Our objective was to investigate the accuracy of the UBT in Japanese patients and the association of UBT values with his

Publikováno v: Scandinavian journal of gastroenterology. 35(3)

Helicobacter pylori has been established as a risk factor for gastric carcinoma (GCa). Since before the discovery of H. pylori, atrophic gastritis and intestinal metaplasia have been linked to GCa, especially the intestinal-type tumor. The prevalence

Publikováno v: Helicobacter. 4(3)

Background. The combination of omeprazole, amoxicillin, and clarithromycin is a common regimen against Helicobacter pylori. Several recent studies have shown that smoking, high intragastric acidity, and the degree of histological gastritis are associ

Comparison of meal-stimulated serum gastrin response in Helicobacter pylori-positive duodenal ulcer and asymptomatic volunteers with and without H. pylori infection

Autor: Ken Haruma, Mitsuhiro Mihara, Koji Sumii, Goro Kajiyama, Tomoari Kamada, Kunihiko Komoto

Publikováno v: Helicobacter. 4(3)

Background. Duodenal ulcer (DU) patients exhibit raised postprandial gastrin release as compared to that in healthy controls. It is believed that serum pepsinogen I (PG I) concentration reflects the chief cell mass and that hyperpepsinogenemia I play

Publikováno v: The American journal of gastroenterology. 93(8)

Several authors have reported an association between Helicobacter pylori (H. pylori) and gastric carcinoma, but the data are conflicting. Atrophic gastritis and intestinal metaplasia (IM) have also been linked to gastric carcinoma, especially the int
