Study Notes

Peptic Ulcer Disease (PUD)

PUD is a well-recognized complication of NSAID use.
Inhibition of COX-1 in the gastrointestinal tract reduces prostaglandin secretion, impacting the gastric mucosa's protective effects. This increases susceptibility to mucosal injury.
NSAIDs disrupt the mucosal permeability barrier, increasing vulnerability to injury. GI adverse effects occur in as many as 30% of adults taking NSAIDs.

Etiology of PUD

H. pylori infection
Drugs (e.g., NSAIDs)
Lifestyle factors (stress, poor diet)
Severe physiologic stress (burns, trauma, surgery)
Hypersecretory states (uncommon)
Genetic factors

NSAID Medications and PUD

NSAIDs can cause PUD.
Risk factors include a history of previous peptic ulcers, advanced age, high doses or combinations of NSAIDs, long-term NSAIDs use, and concomitant use of anticoagulants and/or severe comorbid illnesses.

Other Etiological Factors

Low-dose aspirin for cardiovascular prevention
History of PUD
NSAID use, oral steroids
Tobacco
Stress
Depression
Anemia
Social deprivation
H. pylori and NSAIDs act synergistically to increase PUD development.

NSAID Gastropathy in Children

Prevalence in children is uncertain, but appears increasing in those with chronic arthritis treated with NSAIDs.
Cases demonstrate gastric ulceration from low-dose ibuprofen even after 1 or 2 doses.

Corticosteroids and Other Factors

Corticosteroids alone don't increase PUD risk but can potentiate it when used with NSAIDs.
Mechanisms include enhanced gastrin, parietal cell hyperplasia, increased acid secretion, decreased gastric mucus, and suppressed prostaglandin synthesis.
Evidence for tobacco being a direct PUD risk factor is not definitive.
Alcohol causes gastric mucosal irritation.
Caffeine intake shows limited evidence of increasing duodenal ulcer risk.

Severe Physiologic Stress

Stressful conditions can cause PUD, such as burns, central nervous system trauma, major surgery, severe medical illness.
Stress ulcer prophylaxis exists as a strategy.

Prognosis

Most PUD patients are successfully treated by eradicating H. pylori, avoiding NSAIDs, and using appropriate antisecretory therapy.
Eradication of H. pylori decreases ulcer recurrence rates from 60-90% to approximately 10-20%.

Diagnostic Tests

Test-and-treat strategy for H. pylori is recommended for patients under 55 years old with dyspepsia and no alarm symptoms.
Endoscopy with biopsy, stool monoclonal antigen tests, and serologic tests are also used.

Clinical Presentation

Dyspepsia (including belching, bloating, distention)
Fatty food intolerance/fullness/pain radiating to the back
Heartburn
Chest discomfort
Hematemesis or melena (blood in vomit or stool)
Melena episodes can be intermittent or multiple in a single day.
Rapid bleeding from ulcers may present as hematochezia (blood in stool).
Symptoms consistent with anemia (fatigue, dyspnea).
Sudden onset may signify perforation.
NSAID-induced issues may be silent, especially in the elderly.
Only 20-25% with possible PUD symptoms are diagnosed with ulcers.

Alarm Features

Features prompting gastroenterologist referral:
Bleeding or anemia
Early satiety
Unexplained weight loss
Progressive dysphagia or odynophagia
Recurrent vomiting
Family history of gastrointestinal cancer

Patient Education

Patient education should cover Aspirin/NSAIDs, Alcohol, Tobacco, and Caffeine (coffee, tea, cola).
Other considerations include obesity/weight reduction and stress reduction (as appropriate).

Complications of PUD

Refractory, symptomatic peptic ulcers
Intestinal Obstruction
Intestinal Perforation
Ulcer bleeding, potentially severe, requiring immediate intervention.
Failure of endoscopic therapy to stop bleeding.

Treatment of PUD

Goals: Eradicate H. pylori infection and prevent complications in PUD patients.
Classifications of drugs include:
- Drugs that inhibit gastric acid
- Drugs that neutralize gastric acid (Antacids).
- Ulcer protectives
- Anti-H.pylori drugs

Treatment of PUD—General Principles

Pharmacologic management of acute bleeding from PUD (Proton pump inhibitors or PPIs).
Discontinuing NSAIDS.
PPI maintenance is recommended for patients needing to continue NSAIDS after H. pylori eradication.

Treatment of PUD—Cont'd

Recommended primary therapy for H. pylori infection is PPI-based triple therapy.
Emergency room treatment may include antacids or GI cocktail (antacid with anesthetic).
High-risk patients should be treated with PPIs or H2 blockers for at least one year.
Patients with refractory ulcers may be on indefinite once-daily PPI therapy.

Treatment in Emergency Department

Antacids or GI cocktail (antacid and anesthetic) can treat symptoms.
Empiric H. pylori treatment should be done after infection confirmation.

Bleeding Peptic Ulcers

Endoscopy is key for rapid PUD diagnosis and treatment, reducing surgery need and hospital stay, and thus improving patient outcomes.

Massive Bleeding Management

Massive bleeding is a difficult complication.
Resuscitation involves establishing IV access and considering blood transfusions.
Nasogastric suction is used to empty and contract the stomach.
Emergent surgical or endoscopic interventions might be needed.
IV PPIs may help reduce mortality, re-bleeding and surgical intervention rate.
Significant bleeds usually necessitate ICU admission.

Proton Pump Inhibitor Safety and Monitoring

PPIs generally have good safety profiles but potential adverse effects (especially with long-term, high-dose use):
- Clostridium difficile infection
- Community-acquired pneumonia
- Hip fracture
- vitamin B12 deficiency
- Decreased absorption of certain medications (ketoconazole, iron salts).
- Iron deficiency anemia due to lack of gastric acid to convert ferric iron to ferrous iron.

H. pylori Infection

Gram-negative rod bacteria associated with gastritis, ulcers, and gastric adenocarcinoma.
Transmission is fecal-oral.
Secretes urease to create ammonia, causing an alkaline environment, enabling survival in the stomach.

H. pylori Infection—Cont'd

Recommended primary treatment for H. pylori infection is PPI-based triple therapy.
These regimens frequently cure infection and ulcers in about 85-90% of cases; ulcers may recur without successful eradication.
Spouses and family members of H. pylori positive individuals should also be considered for testing.

PPI-Based Triple Therapies for 14-Day Regimen

Omeprazole (Prilosec), Rabeprazole (Aciphex), Esomeprazole (Nexium), or Pantoprazole.
Combined with antibiotics like Clarithromycin, Amoxicillin (or Metronidazole for allergic patients.)

Quadruple Therapies for H. pylori

Reserved for those in whom standard treatment fails.

Summary

Upper GI endoscopy is the preferred test for suspected PUD.
Early endoscopy is crucial for patients over 45-50, or those with “alarm” symptoms.
PUD can be effectively treated with H. pylori eradication.
Avoidance of NSAIDs and use of appropriate antisecretory drugs also help treat PUD.

Medications

Proton Pump Inhibitors (PPIs).

Proton Pump Inhibitors (PPIs)

Most effective antiulcer therapy drugs.
Need activation in acid environment.
Available options: Omeprazole, Pantoprazole, Lansoprazole, Esomeprazole, Rabeprazole.

PPI Pharmacokinetics

PPIs should be taken 30 minutes to 1 hour before food.
