Background And Aims:
Helicobacter pylori (H. pylori) is a major cause of peptic ulcer disease (PUD) and upper gastrointestinal bleeding. Testing for and eradication of H. pylori reduces the risk of future PUD-related complications including readmission for gastrointestinal bleeding. Our aim was to determine the most cost-effective testing strategy for H. pylori in patients hospitalized with bleeding peptic ulcers.
Methods:
We developed a Markov cohort model to compare the following 6 H. pylori testing strategies: no testing, histology, rapid urease test, stool antigen test, urea breath test (UBT), and serology. Histology and rapid urease test require biopsies, while stool antigen test, UBT, and serology do not. We assumed a 17% H. pylori prevalence in patients admitted with bleeding ulcers. Model outcomes included hospitalizations for rebleeds, number needed to treat to avoid another hospitalization, life expectancy, total cost, quality-adjusted life years, and incremental cost-effectiveness ratios.
Results:
Compared to no testing, UBT resulted in a gain of 0.02 quality-adjusted life years, total cost savings of $2140 per patient, and 1675 hospitalizations avoided per 10,000 patients per year. Additionally, the number needed to treat to avoid an additional hospitalization over 35 years was 167. UBT was the preferred strategy as it was both less costly and more effective than no testing.
Conclusion:
Our findings suggest that UBT is the cost-effective strategy to identify H. pylori in patients admitted with PUD. Noninvasive H. pylori testing at the point of care or during inpatient admission should be considered, as it presents limited risk to patients and offers potential clinical benefits.

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.

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...

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.
