Time to say good bye to routine stress ulcer prophylaxis in ICU

Pantoprazole or Placebo for Stress Ulcer Prophylaxis (POP-UP Study)

In this randomized Double-Blind Exploratory Study by Selvanderan et el 214 patients were randomized to pantoprazole 40mg vs placebo. They found that prophylactic administration of pantoprazole was neither beneficial or harmful to mechanically ventilated critically ill patients who were expected to receive enteral nutrition. There were no episodes of clinically significant gastrointestinal bleeding in either group

HISTORY

Skillman et el in 1969 found that 5% of consecutive ICU patients had stress ulceration. He also proved that Histamine receptor blocker reduced stress ulcers from 25% to 4% in 100 patients. These findings were later confirmed by Cook et el in 1991 and 1996. Another cohort study by Cook et el in 1994 found risk factors of respiratory failure and coagulopathy but by this time, stress ulcer prophylaxis became standard of care.  None of the studies found any mortality benefit. Alhazzani et al.in a metaanalysis of 14 trials found that PPIs were more effective than histamine receptor blockers in reducing both clinical and overt gastrointestinal bleeding. There were only two trials comparing use of proton pump inhibitors with placebo to prevent gastrointestinal bleeding in critically ill patients (Reference 7, 8)

DOUBTS

Krag el el in a systematic review in 2014 showed no difference in the risk of bleeding in groups treated with stress ulcer prophylaxis vs no prophylaxis. Sasabuchi et al compared two groups and  demonstrated no difference in the rate of significant gastrointestinal bleeding, 30-day mortality, or C. difficile infection. Hospital acquired pneumonia was higher in the group treated with stress ulcer prophylaxis.  Selvanderan et al did a prospective randomized double-blind study of  214 mechanically ventilated patients. None of the randomized patients had an episode of clinically significant gastrointestinal bleeding.

HARMS

Likely increases the risk of hospital-acquired pneumonia by colonization of harmful bacteria.( Herzig et al showed 30% increased odds ratio of hospital-acquired pneumonia). Furthermore, the use of gastric acid suppressive therapy together with the use of broad spectrum antibiotics has been associated with an increased risk of Clostridia difficile infection. An increased risk of cardiovascular events in patients receiving PPI has been suggested by various authors. (Reference 12-16)

BOTTOMLINE

Incidence of significant GI bleeding is low in today’s critical care patients. Stress ulcer prophylaxis does not make any difference and may actually harm based on several studies. Moreover, once started on these medications, physicians forget to stop them. It is time to say good bye to routine stress ulcer prophylaxis in critically ill patients.

    Crisp summing up of the latest in the subject. Lucid,readable style. Thanks for the initiative.

    is there any study looking on development of pneumonia in patient recieving GI ulcer prophylaxis.
