Clinical, morphological and immunological data in addition to animal studies clearly support the conclusion, that Campylobacter pylori infection is a direct cause (sufficient condition) for chronic type B gastritic in man. C. pylori gastritis is primarily a histologic entity defined by the presence of a gastric mucosal cellular infiltrate and the histologic demonstration of typical curved bacilli. Preliminary findings indicate, that this infection is not associated with a specific combination of symptoms. Also, it is not exclusively confined to human beings, since this or similar infections appear to represent a rather common phenomenon of mammalian stomachs. The emergence of C. pylori gastritis as a distinct entity may give rise to a new classification of dyspeptic disorders based on etiologic considerations. However, the clinical impact of C. pylori will in all likelihood depend primarily on the as yet unestablished therapeutic potential to effectively eradicate the organisms.

Gastric cancer (GC) is a significant global health challenge, particularly in high-incidence regions like East Asia. Despite improvements in screening and treatment, the progressive nature of precancerous lesions-such as atrophic gastritis, intestinal metaplasia, and dysplasia-necessitates effective prevention strategies. This review evaluates the role of chemoprevention in GC, focusing on agents designed to target these precancerous lesions.

() infection is a known inducer of various gastrointestinal diseases, including gastritis, gastric ulcers, and gastric cancer. However, in recent years, research on the potential association between infection and metabolic dysfunction-associated steatohepatitis (MASH) has been scarce. This large-scale multicenter study, covering more than 360 hospitals across 26 medical systems in the United States, systematically evaluated the association between infection and MASH.

() infection is a typical microbial agent that interferes with the complex mechanisms of gastric homeostasis by disrupting the balance between the host gastric microbiota and mucosa-related factors, ultimately leading to inflammatory changes, dysbiosis, and gastric cancer (GC). We searched this field on the basis of PubMed, Google Scholar, Web of Science, and Scopus databases. Most studies show that inhibits the colonization of other bacteria, resulting in a less variety of bacteria in the gastrointestinal (GI) tract.

Objectives: To investigate the correlation between gastric xanthoma (GX) and precancerous lesions (PCL) and gastric cancer (GC), and to explore other potential risk factors for PCL and GC in northwest China.
Methods: A case-control study was conducted from September 2022 to September 2023 at Xijing Hospital, Air Force Medical University (Xi'an, Shaanxi Province, China). The patients who underwent gastroscopy were enrolled and divided into the chronic gastritis (CG) group (n = 423), PCL group (n = 422), and GC group (n = 415).

Oxyntic gland neoplasms typically arise in Helicobacter pylori-naïve stomachs and are composed predominantly of chief cells, with a smaller component of parietal cells. The pathologic diagnosis can be challenging due to minimal cellular atypia. Especially in biopsy specimens with limited tumor volume or when pathologists have limited experience in diagnosing this neoplasm, distinguishing it from normal oxyntic glands can be difficult, and no reliable diagnostic markers are currently available.
