Evaluating the Accuracy of the Endoscopic ABC Classification System in Diagnosing Helicobacter pylori-Infected Gastritis.

Aims: Evaluating the accuracy of the modified Endoscopic ABC (Endo ABC) classification with an electronic endoscopy with narrow band imaging without magnification in diagnosing Helicobacter pylori (H. pylori)-infected gastritis.

Methods: A total of 576 patients were enrolled and they underwent modified Endo ABC.

[Analysis of the gray-zone cutoff values of new serum Helicobacter pylori antibody kits using latex immunoassay].

The serum Helicobacter pylori titers are good markers for population-based H. pylori screening and treatment programs because the tests used to estimate these titers are noninvasive, inexpensive, and convenient. However, the reference range of 3-10U/mL, which is used as a standard in commercially available serum H.

Prevalence of Helicobacter pylori infection by birth year and geographic area in Japan.

Background: Helicobacter pylori (H. pylori)-related diseases are responsible for a tremendous amount of morbidity and mortality in Japan. We estimated the prevalence of H.

Multi-center randomized controlled study to establish the standard third-line regimen for Helicobacter pylori eradication in Japan.

Backgrounds: The present study sought to establish a standard third-line eradication regimen for Helicobacter pylori in Japan.

Methods: Subjects were 204 patients with H. pylori infection in whom the standard Japanese first- and second-line eradication therapies had proven unsuccessful.

[Cost cut of cancer by a shift in gastric cancer risk screening (serum ABC classification) combined with eradication of H. pylori, and H. pylori test and treatment program in young people].

We estimated the costs and the benefits of a shift strategy of gastric cancer risk screening (ABC stratification) with H. pylori eradication, and H. pylori test and treatment program in young people, comparing with the current barium gastrograph.

Analysis of ABC (D) stratification for screening patients with gastric cancer.

Aim: To evaluate the value of ABC (D) stratification [combination of serum pepsinogen and Helicobacter pylori (H. pylori) antibody] of patients with gastric cancer.

Methods: Ninety-five consecutive patients with gastric cancer were enrolled into the study.
