Objectives: eradication reduces but cannot eliminate the risk of gastric cancer (GC). The prevalence of post-eradication GC has been rising. Characterization of the endoscopic findings of post-eradication GC may facilitate its early detection.

Several methods for the diagnosis of infection exist, including endoscopy, the urea breath test, and the fecal antigen test, which is the serum antibody titer test that is often used since it is a simple and highly sensitive test. In this context, this study aims to find the association between different antibody reactivities and the organization of bacterial genomes.

The present study investigated DEC205-mediated phagocytosis of and the role of DEC205-positive macrophages in the human gastric mucosa. DEC205 mediated phagocytosis of was detected immunocytochemically in PMA-stimulated macrophages differentiated from NOMO1 cells.

Here we report the case of a 73-year-old male who had undergone esophagogastroduodenoscopy (EGD) at a nearby hospital or at our hospital every year since 2006. In 2013, EGD results revealed a discolored lesion, measuring 6mm in diameter, on the anterior side of the upper body in the stomach. Helicobacter pylori (HP) was eradicated in 2010, and the background mucosa around the lesion was endoscopically diagnosed as non-atrophic.
View Article and Find Full Text PDFAtrophic gastritis is caused by Helicobacter pylori infection, and is involved in gastric cancer. In this study, we investigated the association with total IgG and IgG subclass antibodies using several strains isolated from Japanese in H. pylori positive and negative individuals, and gastric atrophy using measuring pepsinogen I and II levels.
View Article and Find Full Text PDFBackground: We previously reported that eradication of Helicobacter pylori in our cohort of patients with peptic ulcer disease reduced their risk of developing gastric cancer to approximately one-third after a mean follow-up period of 3.4 years (up to 8.6 years).
View Article and Find Full Text PDFAtrophy of the gastric mucosa is a precursor of intestinal-type gastric cancer, and Helicobacter pylori infection causes atrophic gastritis. The aim of this study was to determine whether the genetic diversity of H. pylori virulence genes is associated with the development and progression of gastric atrophy in humans.

Methods: Subjects were 204 patients with H. pylori infection in whom the standard Japanese first- and second-line eradication therapies had proven unsuccessful.
Background: We previously reported that the reinfection rate with Helicobacter pylori in Japan was low despite a high prevalence of infection. In the present study, we extended our previous work to more accurately determine the reinfection rate.
Methods: We enrolled 1625 patients (219 women and 1406 men, mean age 50.

We previously reported that eradication of Helicobacter pylori reduced the risk of gastric cancer developing in patients with peptic ulcer diseases. In the present study, we followed up with our patient group to investigate the occurrences and clinical features of gastric cancers that developed after cure of the infection. Prospective post-eradication evaluations were conducted on 1, 674 consecutive patients who had received successful H.

Backgrounds And Aim: The effect on reflux esophagitis of eradicating Helicobacter pylori is variable and not fully defined. We previously reported that in patients who have reflux esophagitis associated with duodenal ulcer, a significant improvement in the pre-existing reflux esophagitis occurred after H. pylori was eradicated.
View Article and Find Full Text PDFBackground/aims: In Helicobacter pylori eradication therapy, using a proton pump inhibitor plus amoxicillin and clarithromycin (PPI/AC regimen), the impact of the clarithromycin dose and smoking on efficacy is conflicting. Here, we compared the efficacy of 400 and 800 mg of clarithromycin in the regimen in relation to smoking in patients with peptic ulcer disease.
Methods: We studied 601 H.
Background: We previously reported that eradication of Helicobacter pylori could reduce the risk of developing gastric cancer in patients with peptic ulcer diseases. In the present study, we further followed up our patient groups to identify factors associated with the development of gastric cancer.
Methods: Prospective posteradication evaluations were conducted in 1342 consecutive patients (1191 men and 151 women; mean age, 50 years) with peptic ulcer disease who had received H.
Objectives: Infection with Helicobacter pylori is a risk factor for the development of gastric cancer. However, it is not known whether eradication therapy can prevent the development of gastric cancer in persons in whom the cancer is not yet established. In the present study, we investigated whether the eradication of H.
