Helicobacter pylori in peptic ulcer disease.

Since William Beaumont's classic description of gastric physiology in 1847, the focus of clinical practice and basic research concerning gastric and duodenal ulcers has centered on the secretion of acid and pepsin. In addition to these well-known factors (largely determined by heredity, age, and oral intake), the search for other agents that alter the mucosal barrier has identified a bacillus, ...

Prevalence of peptic ulcer in Helicobacter pylori positive blood donors.

This study aimed to determine the importance of raised antibodies to Helicobacter pylori in an asymptomatic population. A total of 128 asymptomatic blood donors who were seropositive for H pylori and consented to endoscopy were investigated. These subjects were from a population of 1010 blood donors screened for antibodies to H pylori. A questionnaire was completed to determine if any subjects ...

Mucosal peptic activity during Helicobacter pylori infection in pediatric patients.

Intramucosal peptic activity may participate in the genesis of acute and chronic superficial gastritis. The proteolytic activity of homogenates of gastric mucosa (antrum and body) and duodenum were measured at pH 2.0 (total peptic activity) after exposure to pH 8.0 (pepsinogen) and the activated pepsinogen (pepsin) was calculated in pediatric patients investigated for the presence of Helicobact...

Association of Helicobacter pylori with acid peptic disease in Karachi.

The prevalence of H. pylori infection in 200 dyspeptic patients undergoing upper G.I. endoscopy was investigated by histology and rapid urease test. H. pylori was associated with 86% cases of chronic gastritis, 84.6% cases of duodenal ulcers and 78.5% of gastric ulcers. None of the 15 histologically normal gastric biopsies showed H. pylori.
