Background. There are several diagnostic methods for Helicobacter pylori (H. pylori) infection. A cost-effective analysis is needed to decide on the optimal diagnostic method. The aim of this study was to determine a cost-effective diagnostic method in patients with atrophic gastritis (AG). Methods. A decision-analysis model including seven diagnostic methods was constructed for patients with AG diagnosed by esophagogastroduodenoscopy. Expected values of cost and effectiveness were calculated for each test...

BACKGROUND: Corpus-predominant gastritis index (CGI) is an early histological marker to identify Helicobacter pylori-infected gastric cancer relatives at risk of cancer. This study validated whether CGI is more prevalent in H. pylori-infected nonulcer dyspepsia (NUD) subjects than in duodenal ulcer (DU) controls and whether it is reversible after H. pylori eradication or is correlated with noninvasive biomarkers. MATERIALS AND METHODS: In this longitudinal cohort study, 573 H...

Gastric neuroendocrine tumors (NETs) are classified into three types. Type I gastric NETs are associated with chronic atrophic gastritis. They have a good prognosis and endoscopic resection is the mainstay of treatment. Type II gastric NETs are caused by hypergastrinemia. They have a poorer prognosis, and resection is required to control the disease. Endoscopic versus surgical resection is recommended for the gastric lesion. Type III gastric NETs are sporadic and not associated with any specific condition. They have the worst prognosis with the highest rate of metastatic disease, and oncologic resection is recommended...

Gastric cancer is an inflammation-associated malignancy aetiologically related to infection with the bacterium, Helicobacter pylori, which is considered a necessary but insufficient cause. Unless treated, H. pylori causes life-long acute and chronic gastric inflammation resulting in progressive gastric mucosal damage that may result in gastric cancer. The rate of progression from superficial gastritis, to an atrophic metaplastic mucosa, and ultimately to cancer relates to the virulence of the infecting H. pylori as well as host and environmental factors...

Sjögren syndrome (SS) is characterized by lymphocytic infiltration of exocrine glands, mainly the lacrimal and salivary glands, leading to keratoconjunctivitis sicca and xerostomia. SS is one of the most common autoimmune rheumatic diseases in adults; however, few cases of primary childhood SS with gastrointestinal and liver lesions have been reported in the literature. We report five cases of primary childhood SS with gastrointestinal and liver lesions. Multiple gastric biopsies in four cases revealed atrophic gastritis in the antrum of the stomach or chronic gastritis...

REVIEW
Steven F Moss
Gastric cancer has long been recognized to be accompanied and preceded by chronic gastritis, lasting decades. Arguably, the most important development in our understanding of gastric cancer pathogenesis over the past 50 years has been the realization that, for most cases of gastric cancer, Helicobacter pylori is the cause of the underlying gastritis. Gastritis can promote gastric carcinogenesis, typically via the Correa cascade of atrophic gastritis, intestinal metaplasia, and dysplasia. Nested case-control studies have shown that H pylori infection increases the risk of gastric cancer significantly, both of the intestinal and diffuse subtypes, and that H pylori is responsible for approximately 90% of the world's burden of noncardia gastric cancer...

Gastric cancer (GC) is one of the most common malignant tumors and the Kazakh population in Xinjiang has been reported to be one of the highest incidence of GC in the world. Serum pepsinogen (PG) test provides a valuable method for detecting GC, but little study about the role of PG in Kazakh GC. Therefore, we aimed to investigate the role of PG in Kazakh GC and to elucidate the usefulness of the serum PG test method. The serum PG concentration were measured using the flow fluorescence assay and ELISA methods in patients with superficial gastritis, atrophic gastritis and GC...

Changes in diet, lifestyle and exposition to environmental risk factors account for the increased incidence of pancreatic disorders, including acute and chronic pancreatitis, and pancreatic cancer. The role of the microbiome in the development of pancreatic disorders is increasingly recognized. The translocation of gut bacteria and endotoxins following gut barrier failure is a key event contributing to the severity of acute pancreatitis, while small intestine bacterial overgrowth is common in patients with chronic pancreatitis and further worsens their symptoms and malnutrition...

At present there is no universally accepted classification for gastritis. The first successful classification (The Sydney System) that is still commonly used by medical professionals was first introduced by Misiewicz et al in Sydney in 1990. In fact, it was the first detailed classification after the discovery of Helicobacter pylori by Warren and Marshall in 1982. In 1994, the Updated Sydney System was proposed during the International Workshop on the Histopathology of Gastritis followed by the publication in The American Journal of Surgical Pathology by Dixon et al...

Chronic atrophic autoimmune gastritis (CAAG) is an organ-specific autoimmune disease characterized by an immune response, which is directed towards the parietal cells and intrinsic factor of the gastric body and fundus and leads to hypochlorhydria, hypergastrinemia and inadequate production of the intrinsic factor. As a result, the stomach's secretion of essential substances, such as hydrochloric acid and intrinsic factor, is reduced, leading to digestive impairments. The most common is vitamin B12 deficiency, which results in a megaloblastic anemia and iron malabsorption, leading to iron deficiency anemia...

The gut microbiota may be considered a crucial "organ" of human body because of its role in the maintenance of the balance between health as well as disease. It is mainly located in the small bowel and colon, while, the stomach was long thought to be sterile in particular for its high acid production. In particular, stomach was considered "an hostile place" for bacterial growth until the identification of Helicobacter pylori (HP). Now, the stomach and its microbiota can be considered as two different "organs" that share the same place and they have an impact on each other...

BACKGROUND: Complex I is the first enzyme complex in the mitochondrial respiratory chain, responsible for generating a large fraction of energy during oxidative phosphorylation. Recently, it has been identified that complex I deficiency can result in increased inflammation due to the generation of reactive oxygen species by innate immune cells. As a reduction in complex I activity has been demonstrated in human stomachs with atrophic gastritis, we investigated whether complex I deficiency could influence Helicobacter pylori pathogenesis...

A man in his 60s was referred to our institution for the evaluation of a gastric neuroendocrine tumor (G-NET) located in the fornix and that measured 13mm in size. Blood test results revealed hypergastrinemia (up to 3376pg/ml). Additional tests, including esophagogastroduodenoscopy, computed tomography, and intragastric pH monitoring, indicated that hypergastrinemia was not associated with type A autoimmune gastritis or gastrinoma. The patient was positive for the immunoglobulin G antibody against Helicobacter pylori, suggesting type B chronic atrophic gastritis as the cause for the condition...
