Abstract:
Objective: The objective of this study is to assess the dynamics of Helicobacter pylori infection prevalence among adults in Russia. Methods: A systematic search was conducted in MEDLINE/PubMed, EMBASE, Cochrane, RSCI, and Google Scholar for studies published between 1985 and 27 February 2025, following PRISMA guidelines. The meta-analysis was registered in PROSPERO (CRD420251011643). Results: Twenty studies were included (n = 117,841; weighted mean age: 43.71 ± 16.23 years), all using validated diagnostic methods. The pooled prevalence from 1994 to 2024 was 62.847% (95% CI: 55.101-70.274), including 45.143% (95% CI: 41.390-48.923) by the 13C-urea breath test and 75.806% (95% CI: 64.213-85.742) by serology. Prevalence declined over time: it was 79.334% before 2005, 74.074% in 2006-2011, and 66.319% in 2012-2017, and it has been 42.949% since 2018. Meta-regression confirmed a significant decrease (coefficient: -3.773% per year, p < 0.001). Conclusions: A significant decline in the prevalence of H. pylori has been observed, however, it remains relatively high and requires continued efforts aimed at diagnosis and eradication.

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
