Study Notes
Peptic Ulcer Disease: Overview
- Peptic ulcer disease involves a breach in gastric or duodenal mucosa due to imbalance between mucosal defense factors and aggressive luminal factors like acid and pepsin.
- Ulcers can be more than 5 mm in size, contrasting with superficial erosions.
Acid Secretion Regulation
- Acid secretion is stimulated by acetylcholine, histamine, and gastrin; inhibited by somatostatin, released by gastric epithelium's endocrine cells.
- Other inhibitors include glucagon-like peptide, CCK, VIP, leptin, and amylin.
Zollinger-Ellison Syndrome
- Characterized by gastrin-secreting tumors (gastrinomas) leading to hypergastrinemia and acid hypersecretion.
- Gastrinomas primarily arise in the pancreas (25%), duodenal wall (45%), and lymph nodes (5-15%).
- Over two-thirds of gastrinomas are malignant, often metastasizing to the liver initially.
- Clinical signs include refractory peptic ulcers, possible diarrhea, and weight loss due to excessive acid causing gastrointestinal mucosal injury.
Complications of Peptic Ulcers
- Perforation: Occurs in less than 5% of ulcer patients, often presenting as sudden, severe abdominal pain.
- Symptoms may include rigid abdomen and rebound tenderness.
- Diagnosis commonly established via abdominal CT, with treatment potentially involving surgery.
- Gastric Outlet Obstruction: Found in less than 2% of ulcer cases, symptoms include early satiety, vomiting, and weight loss.
- Diagnosis requires endoscopy to rule out neoplasms; treatment options include fluid replacement and potentially surgery.
Helicobacter pylori Infection
- A spiral gram-negative rod causing gastritis and linked to 80-89% of non-cardia gastric cancers.
- Commonly transmitted among low socioeconomic groups; results in acute gastritis and may evolve to chronic inflammation.
- Antrum-predominant infections elevate gastrin levels, leading to duodenal ulcers.
- Testing for H pylori is recommended for patients with a history of peptic ulcer disease and other relevant conditions.
Etiology of Peptic Ulcer Disease
- Major causes include NSAIDs and chronic H pylori infection; both should be investigated in ulcer patients.
- Alcohol, diet, and stress do not significantly contribute to ulcer formation.
- Less than 5-10% of ulcers may result from other conditions like Zollinger-Ellison syndrome, medications, or chronic illness.
Prevalence and Impact
- H pylori found in 70-90% of duodenal ulcer patients, whereas NSAID-induced ulcers occur in 10-20% of long-term NSAID users.
- Low-dose aspirin also doubles the risk of gastrointestinal bleeding complications.
