Infection of Helicobacter pylori and Atrophic Gastritis Influence Lactobacillus in Gut Microbiota in a Japanese Population
نویسندگان
چکیده
Methods: A total of 1,123 adult subjects who participated in a health survey in Hirosaki City were studied. Infection of H. pylori was defined by both serum antibody and stool antigen test. The presence and the severity of atrophic gastritis were defined by the serum level of serum pepsinogens. Using 16S ribosomal RNA amplification from fecal samples, the relative abundance of Lactobacillus was calculated, and the composition ratio of each Lactobacillus species was surveyed.

Seroepidemiology of gastritis in Japanese and Dutch working populations: evidence for the development of atrophic gastritis that is not related to Helicobacter pylori.
Serological markers of gastritis, like pepsinogen A, pepsinogen C, gastrin, and Helicobacter pylori antibodies, can be used to explore the state of the gastric mucosa in populations with contrasting cancer risks. A decreasing pepsinogen A:C ratio and an increasing serum gastrin are known to reflect an increasing severity of atrophic corpus gastritis, which is a precursor of gastric cancer. In 7...
متن کاملHelicobacter pylori infection is associated with a decreased risk of tooth loss in healthy Japanese men.
The association between Helicobacter pylori infection and tooth loss has been studied in Western countries; however, this relationship remains controversial. Although the prevalence of H. pylori infection is higher and atrophic gastritis is usually observed in patients with H. pylori infection in Japan unlike that in Western population, no study has examined the association between H. pylori in...

متن کاملHelicobacter pylori infection, glandular atrophy, intestinal metaplasia and topography of chronic active gastritis in the Nepalese and Japanese population: the age, gender and endoscopic diagnosis matched study.
BACKGROUND The incidence and mortality from gastric cancer is high in Japanese but extremely low in Thailand. It is different among Asian countries. The aim of this study is to investigate the difference of peptic ulcer disease, glandular atrophy, intestinal metaplasia and topography of chronic active gastritis between the Nepalese and Japanese population. MATERIALS AND METHODS Nepalese patie...
متن کاملGastric epithelial cell kinetics in the progression from normal mucosa to gastric carcinoma.
Increased epithelial cell proliferation is associated with an increased risk of adenocarcinoma and is associated with Helicobacter pylori infection. The aim of this study was to assess both gastric epithelial cell proliferation and the influence of H pylori infection on cell kinetics in the progression from normal mucosa to gastric carcinoma. One hundred and forty four subjects were assigned to...
