Settings: multinational, randomized, double- blind, placebo-controlled clinical trial conducted in 17 centers in Italy, Russia, and Kazakhstan
Participants: A total of 307 ICU patients with sepsis or septic shock. Patients who were likely to die (APACHE II > 65 points) were excluded.
Treatment group: 80 mg bolus of omeprazole at randomization, at 12 hours and infusion of 12 mg/hour for 72 hours. Total dose of 1024 mg.
Outcome measurement: primary outcome of the study was organ dysfunction measured as the mean daily SOFA score during the first 10 days. Secondary outcomes were antibiotics-free days at 28 days; all-cause mortality at 28 days
Study Results:
- At 10 days, there was no difference in the median mean daily SOFA score: 5 (IQR, 3–10) in the mega- dose esomeprazole and 5 (IQR, 3–9) in the placebo groups (risk difference [RD], 0.1; 95% CI, –0.8 to 1.0; p > 0.99).
- At day 28, the median antibiotic-free days were 15 (IQR, 0–21) in the mega-dose esomeprazole group vs. 13 (IQR, 0–21) in the placebo group (p = 0.62).
- All-cause mortality at 28 days was 25% in the mega- dose esomeprazole group and 20% in the placebo group (RD, 4.9; 95% CI, –4.5 to 14.2; p = 0.31).
Discussion:
- The authors also did in vitro assays and they detected reduced levels of anti-inflammatory cytokines among patients receiving megadose of omeprazole. However, these in vitro results did not translate into clinical benefits in these patients with sepsis.
- Apparently, this study is another example that animal studies may not translate into clinical benefits in human studies, especially sepsis , as this condition is highly heterogeneous.
Conclusion:
In sepsis patients, Esomeprazole did not re- duce organ dysfunction, despite demonstrating in vivo immunomodulatory effects
