Study Notes

Peptic Ulcer Disease (PUD)

PUD is a recognized complication of NSAID use.
NSAID use inhibits COX-1 in the gastrointestinal tract, decreasing prostaglandin secretion and its protective effects on the gastric mucosa. This increases susceptibility to mucosal injury.
NSAIDs disrupt the mucosal permeability barrier, making the mucosa vulnerable to injury.
Up to 30% of adults taking NSAIDs experience adverse GI effects.
Risk factors include a history of previous PUD, advanced age, high doses/combinations of NSAIDs, long-term NSAID use, concurrent use of anticoagulants, and severe comorbid illnesses.

Etiology

PUD can be caused by H.pylori infection.
Lifestyle factors contribute to PUD.
Severe physiological stress can cause PUD.
Hypersecretory states (uncommon) can lead to PUD.
Genetic factors can also play a role in PUD.
Low-dose aspirin is used for cardiovascular prevention.
History of PUD, NSAIDs, oral steroid agents and tobacco use can contribute to PUD.
Stress, depression, anemia and social deprivation are other contributing factors.
H. pylori and NSAIDs have a synergistic effect in PUD development.

NSAID Gastropathy in Children

Prevalence in children is unknown but seems to be increasing, particularly in children receiving NSAIDs for chronic arthritis.
Case reports show gastric ulceration can occur in children even after a single or two doses of ibuprofen.

Corticosteroids and Other Factors

Corticosteroids alone do not increase the risk of PUD; however; they can increase ulcer risk if used alongside NSAIDs.
Mechanisms responsible for corticosteroid-induced PUD include enhanced gastrin and parietal cell hyperplasia, increased acid secretion, diminished gastric mucus synthesis, and suppressed arachidonic acid and prostaglandin (PG) synthesis.

Lifestyle Factors

The link between tobacco use and duodenal ulcers is inconclusive.
Alcohol causes gastric mucosal irritation.
Caffeine intake does not appear to be a significant risk factor for duodenal ulcers.

Severe Physiological Stress

Stressful conditions such as burns, CNS trauma, surgery, and severe medical illnesses can cause PUD.
Stress ulcer prophylaxis exists.

Prognosis

Most patients with PUD can be successfully treated, often utilizing:
- Eradication of H. pylori infection.
- Avoidance of NSAIDs.
- Appropriate antisecretory therapy use.
Studies demonstrate that successful eradication of H. pylori reduces ulcer recurrence rates from 60-90% to approximately 10-20%.

Diagnostic Tests

Test-and-treat strategy for H. pylori is recommended for individuals under 55 with dyspepsia and no alarm symptoms.
Endoscopy with biopsy is used for diagnosis.
Stool monoclonal antigen tests are available.
Serologic tests are also used.

Clinical Presentation

Dyspepsia, including belching, bloating, distension, intolerance of fatty foods, fullness, and pain radiating to the back can occur.
Heartburn and chest discomfort are common symptoms.
Hematemesis or melena can result from gastrointestinal bleeding.
Melena may be intermittent or appear in multiple episodes within a day.

Other Possible Manifestations

Rarely, brisk bleeding ulcers may present as hematochezia.
Symptoms indicative of anemia (e.g., fatigue, dyspnea).
Sudden symptom onset may indicate perforation.
Silent NSAID-induced gastritis or ulcers may occur in elderly patients.
20-25% of patients with suspected PUD symptoms actually have this condition on investigation.

Alarm Features

Bleeding or anemia.
Early satiety
Unexplained weight loss.
Progressive dysphagia or odynophagia.
Recurrent vomiting.
Family history of gastrointestinal cancer. These warrants prompt referral to a gastroenterologist.

Patient Education

Patient education should cover:
- NSAIDs, aspirin
- Alcohol
- Tobacco
- Caffeine (e.g., coffee, tea, cola)
- Obesity and weight reduction.
- Stress reduction

Complications of PUD

Refractory, symptomatic peptic ulcers.
Intestinal obstruction.
Intestinal perforation.
Ulcer bleeding, especially in patients with a history of massive hemorrhage and hemodynamic instability.
Endoscopic therapy failure to control bleeding warrants intensive management.

Treatment of PUD

Goals of therapy include eradicating H. pylori infection and preventing complications.

Classification of Drugs used in PUD

Drugs that inhibit gastric acid secretion.
Drugs that neutralize gastric acid (Antacids).
Ulcer protectives.
Anti H. pylori drugs.

Treatment of Peptic Ulcer Disease - General Principles

Pharmacologic management of acute bleeding from PUD.
- Acid suppression using proton pump inhibitors (PPIs).
- Both preparations are available in intravenous and oral options.
Discontinue NSAIDs (if possible).
PPI maintenance for patients requiring continued NSAID use, even following H. pylori eradication.

Treatment of Peptic Ulcer Disease - Emergency Room Treatment

Antacids or GI cocktail (Typically an antacid combined with anesthetic such as viscous lidocaine, and/or an antispasmodic) for symptomatic relief.
PPI-based triple therapy is the recommended primary therapy for H. pylori infection.
High-risk patients are treated with PPIs or H2RAs for one year.
Refractory ulcers may receive once-daily PPI therapy indefinitely.

Treatment in the Emergency Department

Antacids or gastrointestinal (GI) cocktails (typically an antacid with anesthetic like viscous lidocaine and/or antispasmodic) can be used for symptomatic treatment.
Empiric H. pylori treatment is not recommended without confirming infection.

Bleeding Peptic Ulcers

Endoscopy is essential for rapid diagnosis and treatment of bleeding PUD.
Endoscopic therapy reduces recurrent bleeding and surgery likelihood.
Endoscopy decreases the length of hospital stays

Massive Bleeding Management

Massive bleeding is a challenging complication.
Resuscitation strategies include intravenous access and potential blood transfusion.
Nasogastric suction may help to empty and contract the stomach.
Emergent surgical interventions may be required.
IV PPIs reduce upper GI bleed mortality.
IV PPIs reduce the need for surgical intervention

Proton Pump Inhibitor Safety and Monitoring

PPIs generally have a good safety profile.
Potential adverse effects include:
- Clostridium difficile infection.
- Community-acquired pneumonia.
- Hip fracture and vitamin B12 deficiency.
Decreased absorption of some medications (e.g., ketoconazole, iron salts).
Iron deficiency anemia, resulting from achlorhydria (absence of intragastric acidity).

H. pylori Infection

Gram-negative rod associated with gastritis, gastric and duodenal ulcers, and gastric adenocarcinoma.
Transmission is typically fecal-oral.
H. pylori secretes urease, converting urea into ammonia.
This creates an alkaline environment enabling bacterial survival in the stomach.

H. pylori Infection Treatment & Regimens

The recommended primary therapy for H. Pylori is PPI-based triple therapy.
Roughly 85-90% of cases demonstrate a cure of both infection and ulcer healing.
Recurrence is possible in the absence of successful H. pylori eradication.
Spouses and family members should be evaluated for testing and treatment.

PPI-based Triple Therapies for 14-Day Regimens

14-day regimens usually involve Omeprazole, Rabeprazole, or Esomeprazole (plus Clarithromycin and Amoxicillin). Metronidazole may be used for Penicillin-allergic patients.

Quadruple Therapies for H. pylori Infection

Quadruple therapies are used when standard treatment regimens fail.

Summary

Upper GI endoscopy is the preferred diagnostic method for suspected PUD.
Early endoscopy is recommended for patients over 45-50 with alarm features.
PUD can often be treated with either H. Pylori eradication, NSAID avoidance, or antisecretory therapy.

Medications

Proton Pump Inhibitors (PPIs)

The most effective antiulcer drugs.
Prodrugs that require activation in an acidic environment.
Available Options: Omeprazole, Pantoprazole, Lansoprazole, Esomeprazole, and Rabeprazole.

PPI Pharmacokinetics Considerations

Administer 30 minutes - 1 hour before meals.
