Study Notes
- Peptic ulcer refers to a condition where sores develop in the lining of the stomach, upper small intestine, or esophagus.
- Peptic ulcer disease (PUD) involves ulcerative disorders in the upper GI tract, requiring acid and pepsin for their formation.
- Ulcers extend deeper into the muscularis mucosa, unlike gastritis and erosions.
Pathophysiology
- Most peptic ulcers occur because of acid and pepsin.
- Helicobacter pylori (HP), NSAIDs, and stress are common risk factors.
- Mucosal defense, which includes mucus, bicarbonate secretion, intrinsic epithelial cell defense, and mucosal blood flow, is crucial in preventing peptic ulcers.
- Mucosal integrity and repair depends on endogenous prostaglandin production.
- HP infection causes gastritis in all infected individuals.
- Approximately 20% of infected individuals develop symptomatic PUD.
- HP may cause ulcers directly via bacterial enzymes or indirectly by altering the immune response and increasing acid secretion.
- NSAIDs, even aspirin, cause gastric mucosal damage due to direct irritation and systemic inhibition of the COX-1 enzyme.
- Corticosteroids alone do not elevate ulcer risk, but combined with NASAIDs can double the risk.
- NSAIDs can be irritant to the stomach lining directly
- If the dose is over 500mg of aspirin it act as analgesic and antipyretic, in higher doses it acts as a nonselective NSAID
- Enteric coated NSAIDs do not cause as much irritation but effect prostaglandin
- Smoking increases ulcer risk, and risk is proportional to the amount smoked per day
- Clinical observations suggest ulcers are adversely affected by stressful life events
Other Risk Factors to Consider
- Coffee, tea, cola beverages, beer, milk and spices may cause dyspepsia; however, they do not increase PUD risk directly.
- High concentrations of ethanol consumption is correlated with acute gastric mucosal damage and upper GI bleeding, but is not a definite cause of ulcers.
Clinical Presentation
- Abdominal pain is the most frequent symptom of PUD.
- The pain is often localized in the epigastric region, described as burning, or experienced as vague discomfort, abdominal fullness, or cramping.
- A typical symptom is nocturnal pain that awakens patients, particularly between 12 AM and 3 AM.
- Heartburn, belching, and bloating are often present.
- Nausea, vomiting, and anorexia are more common in Gastric Ulcers (GU) then Duodenal Ulcers (DU).
- Pain from DU often occurs 1 to 3 hours after meals, Is usually relieved by food
- GU food may precipitate or accentuate ulcer pain, gastric acid production is increased as food enters the stomach
Management
- The severity of symptoms varies from patient to patient, they may be seasonal, spring or fall.
- Antacids provide rapid pain relief.
Diagnosing Complications
- Complications include upper GI bleeding, perforation, gastric outlet obstruction, weightloss, more nausea
- Diagnosis made through hemoglobin tests, stool tests, history of patient
- Endoscopy preferred method to verify HP eradication after treatment
- H pylori tests must be delayed for at least 4 weeks after treatment to avoid confusion
- UBT is the preferred nonendosocpic method to verify HP eradication after treatment
Desired Treatment
- Relieving ulcer pain is main goal
- Healing the ulcer and reducing related complications can be treated with PPI's
- Prevent ulcer recurrence
Nonpharmacologic alternatives
- Patients should eliminate or reduce, stress, smoking and nonselective NASIDs
- They also should avoid foods and beverages that cause dyspepsia (spicy foods, caffeine, alcohol)
Pharmacologic Alternatives - HP
- Help Eradicate the bacteria for H. Pyloria patients. Use bacterias that dont have a side effect
- First line of eradication is theproton pump inhibitor with three drug regimen
- It usually contains clarithromycin along with amoxicillin
Diagnosing
- Visualize the ulcer depending on PUD by upper GI radiography or endoscopy
- Endoscopy has largely replaced largely replaced radiography
- Endoscopy provides direct visisualization of ulcer
