Abstract:
Helicobacter pylori (H. p.) causes active chronic antrum gastritis in all infected patients. In a relatively small percentage complications of H. p.-gastritis including duodenal ulcer, gastric ulcer, giant fold gastritis, lymphocytic gastritis, autoimmune gastritis, gastric carcinoma and gastric MALT lymphoma may develop. Strongly recommended indications for eradication therapy include gastroduodenal ulcer disease, giant fold gastritis, lymphocytic gastritis, autoimmune gastritis, gastric MALT lymphoma, atrophic gastritis, corpus-predominant gastritis, post gastric cancer resection and patients who are first degree relatives of gastric cancer patients. Eradication therapy is controversial in patients with gastroesophageal reflux disease, functional dyspepsia and in patients in whom treatment with nonsteroidal antiinflammatory drugs (NSAID) or long-term treatment with proton pump inhibitors (PPI) is planned.

Gastritis III: Clinical Manifestations and Management
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...
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 IV: Management
The therapeutic approach involves ensuring adequate rest, implementing drug therapy, promoting smoking cessation, making dietary modifications, and emphasizing long-term follow-up care.
Pharmacological management
The prevailing therapy for peptic ulcers involves a combination of managing the patient's current medication...
