Gastrointestinal neuroendocrine tumors are a group of highly heterogeneous tumors. Their incidences have increased in the Western countries as well as in Asia for years. In recent years, predominant progression has been made in the basic and translational studies on gastrointestinal neuroendocrine tumors. Gastric neuroendocrine neoplasmas are classified as four types: type I( occurs on the basis of autoimmune atrophic gastritis, type II( clinically manifests as multiple endocrine tumor type I( and Zollinger-Ellison syndrome, type III( is sporadic neuroendocrine neoplasmas, and type IIII( is neuroendocrine carcinoma...

INTRODUCTION: Helicobacter pylori is a Gram-negative, microaerophilic bacterium that colonizes human gastric mucosa. Gastric ulcer, duodenal ulcer, chronic atrophic gastritis, mucosa-associated lymphoid tissue lymphoma, and stomach adenocarcinoma are associated with H. pylori as the etiological agent. Cytotoxin-associated gene A (cagA), which is one of the most important virulence factors of H. pylori, encodes a 120-145 kDa protein. The prevalence of cagA genes shows differences in H...

Most patients with iron deficiency anemia are treated effectively with oral iron preparations. However, a small number of these patients are refractory to such treatments, even when the pathologic condition underlying the anemia is concurrently treated. The pathological basis for this refractoriness can be explained by several factors, including malabsorption of iron, e.g. atrophic gastritis, deficiency of other hematopoietic vitamins or minerals, e.g. vitamin B12 or zinc, other undiagnosed anemic disorders, e...

BACKGROUND: Helicobacter pylori (H. pylori) infection and eradication therapy have been known to influence gastric ghrelin and leptin secretion, which may lead to weight gain. However, the exact relationship between plasma ghrelin/leptin levels and H. pylori infection has remained controversial. The aim of this study was to investigate plasma ghrelin and leptin levels in H. pylori-positive and -negative patients, to compare the two levels of the hormones before and after H. pylori eradication, and to examine the correlation between body mass index (BMI) and active ghrelin or leptin levels, as well as that between atrophic pattern and active ghrelin or leptin levels...

Helicobacter pylori infection has accompanied man for thousands of years. In some infected patients, a complex and dynamic pathogen-host reaction triggers pathogenic pathways resulting in development, inter alia, of atrophic gastritis, peptic ulcer disease (both gastric and duodenal), gastric adenocarcinoma, and MALT lymphoma. Large-scale eradication therapy is associated with a rapid increase in antibiotic resistance, gut flora composition disturbances, and increased risk of development, inter alia, of paediatric infectious diarrhoeas, atopic diseases, and oesophageal adenocarcinoma...

BACKGROUND: The effect of H. pylori eradication in gastric cancer prevention can be attributed to the improvement of atrophic gastritis, which is a known risk of gastric cancer. However, gastric cancer has also been diagnosed after long-term H. pylori eradication. This study aimed to clarify the association between gastric atrophy and gastric cancer after H. pylori eradication, including its clinicopathological features. METHODS: A total of 55 consecutive patients with 64 early gastric cancers (EGCs) diagnosed after H...
