    Study Notes

    Risk Factors for SRMB

    • Patients at risk for stress-related mucosal bleeding (SRMB) include those with respiratory failure requiring mechanical ventilation, and coagulopathy (INR >1.5), along with two or more of the following: platelet count <250 mg/day of hydrocortisone, multiple trauma, severe burns covering more than 35% of body surface area, head injury, traumatic spinal cord injury, major surgery, prolonged ICU stay (>7 days), or a history of gastrointestinal (GI) bleeding.

    SRMB Treatment and Prophylaxis

    • Antisecretory therapy is preferred for SRMB prophylaxis due to its effectiveness.
    • Parenteral Histamine-2 receptor antagonists (H2RAs) can be administered via continuous infusion or intermittent bolus dosing.
    • Intravenous ranitidine is found to be superior to oral sucralfate in preventing SRMB without increasing the risk of nosocomial pneumonia.
    • H2RAs are recommended for SRMB prevention although Proton Pump Inhibitors (PPIs) are considered the mainstay option.
    • Limited evidence suggests no clinical superiority of PPIs over H2RAs or placebo.

    Pharmacotherapy Plan for SRMB Prevention

    • Selecting the pharmacotherapy plan for SRMB prevention depends on the patient's clinical presentation and medication costs.
    • Patients able to take oral medications or have a working NG tube should use oral or compounded PPI suspensions as a cost-effective option.
    • If oral routes are unavailable, intravenous H2RAs should be utilized.
    • Prophylactic therapy should be discontinued upon resolution of risk factors, patient discharge from ICU, extubation, or the capability for oral intake.

    Noninvasive Diagnosis of PUD

    • Urea breath tests (sensitive and specific for H. pylori infection) may yield false negatives with antibiotic or PPI use.
    • Serologic tests detect H. pylori antibodies with 85% sensitivity but are not effective for monitoring eradication.
    • Stool antigen tests for active H. pylori infection show 88-92% sensitivity and can be influenced by bismuth, PPI, and antibiotic use.

    Treatment Goals for PUD

    • Primary goals include rapid symptom relief, ulcer healing, prevention of recurrences, reducing ulcer-related complications, and minimizing morbidity and mortality.
    • Treatment varies based on ulcer etiology, initial vs. recurrent status, and presence of complications.
    • For H. pylori-positive patients, eradication is defined by negative results on breath or stool antigen testing at least six months post-treatment.

    NSAID-Induced PUD Management

    • Management involves healing existing ulcers and preventing new ulcers in patients who are currently ulcer-free.
    • Key strategies for prevention include using the least GI-toxic agent at the lowest effective dose.
    • Options include discontinuing NSAIDs, administering H2RAs or PPIs for eight weeks, or switching to acetaminophen or non-acetylated salicylates combined with antisecretory agents for 12 weeks.

    Pharmacologic Agents for PUD

    • Proton Pump Inhibitors (PPIs) are effective for NSAID-induced ulcers.
    • Misoprostol is indicated for NSAID-induced ulcers but may cause diarrhea and cramping.
    • H2 Receptor Antagonists (like Cimetidine) are less preferred for prevention.

    PPI Overview

    • Various PPIs including rabeprazole, pantoprazole, esomeprazole, and dexlansoprazole are available for ulcer management.
    • Common side effects of PPIs include headache, dizziness, rash, and gastrointestinal disturbances.
    • Specific dosages and administration routes vary across PPI types, with most requiring adult usage of up to 16 weeks or more.

    Risk Factors and Recurrence of PUD

    • Recurrence rates of PUD are higher in populations with certain risk factors.
    • Alternative eradication regimens may be required based on symptoms and complication risk profile.
    • Emerging studies will determine if shorter courses of eradication therapy might influence resistance rates.
