Abstract:
The prevalence of H. pylori infection in AIDS patients has been controversial. A. controlled prospective and descriptive study was conducted in a group of 64 HIV-infested patients. H. pylori detection was carried out by endoscopic study during which two biopsy samples of gastric antrum and body were taken for the histologic study and other 2 samples of gastric antrum and body for urease testing. H.pylori infection prevalence was 56.3%. The comparison group was composed by 110 serologically HIV-negative patients, with an infection prevalence rate of 77.2%. In the HIV-AIDS group, the frequency of gastric ulcer was 1,5% and no duodenal ulcer was found whereas the comparison group showed a frequency of gastric and duodenal ulcers of 1.8 and 15.5% respectively. HIV+/AIDS patients in category I exhibited an H. pylori infection prevalence of 68.7%, category II, 39.2% and category III, 21,0%. A reversed association was observed between the level of immune deterioration and the prevalence of H. pylori infection.

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.
