Medical Therapies for Stable Upper Gastrointestinal Bleeding: Risk, Benefit and Equivocality

 

Epidemiology

• Incidence: 40-150 per 100,000 per annum, with 450,000 hospitalizations in the USA
• Causes: peptic ulcer (~45%); gastro-duodeno-esophagitis (25%); varicies (~15%) Other (Mallory-Weiss tear, tumor, angiodysplasia, aorto-enteric fistula)

 

Medical Therapies

Proton Pump Inhibitors (PPIs)

PPIs irreversibly block the hydrogen/potassium ATPase in parietal cells allowing pH to rise which theoretically promotes clot stability and decrease the likelihood of rebleeding

UGIB undifferentiated:

  • No reduction in Mortality, need for surgery or rebleeding
  • A reduction in the grade of lesion found at time of endoscopic evaluation was found.
    • Systematic review of 4 randomized trials of ~1500 patients (Sreedharan, 2010)

UGIB Peptic Ulcer:

  • No reduction in Mortality (OR 1.01, 95%CI 0.74-1.40) or blood transfusion requirements
  • Rebleeding was reduced NNT 15
    • Systematic review of 24 randomized trials of 4373 patients (Leontiadis, 2006)

 

Somatostatin Analogs (Octreotide)

Decreases blood flow in portal circulation thereby decreasing portal pressure

UGIB Variceal

  • No reduction in Mortality
  • PRBC transfusions reduced by 0.7 U in conjunction with endoscopictreatment (NNT=6)
    • Systematic review of 21 randomized trials of 2588 patients (Gøtzsche, 2008)

 

Prophylactic Antibiotics

Cirrhotics have impaired immune function and increased translocation of bacteria, therefore prophylactic antibiotics during bleeding may be helpful taking into account that mortality in variceal bleeding is ~ 20% with infection accounting for almost half of all deaths

UGIB Variceal

  • Reduction in Mortality NNT = 22
  • Reduction in infections NNT = 4 (PNA, UTI, SBP)
    • Systematic review of 12 trials of 1241 patients (Chavez-Tapia, 2010)
      • 1 was placebo controlled and Abx choices varied (gram negative coverage)
