简要总结
Sepsis is a severe disease with a high mortality rate and lack of efficacious therapies. Proton pump inhibitors (PPI) are drugs widely used to inhibit acid secretion by gastric cells and with a high safety profile. Carta and Rubartelli (IRCCS San Martino - Genova) have recently reported that PPI, such as esomeprazole, inhibit TNF-alfa and IL-1ß secretion. Moreover, they showed that a single administration of PPI protects mice from endotoxic shock with no adverse effects. PPI-SEPSIS is a randomized, double blind, controlled against placebo clinical trial to test if high-doses esomeprazole in septic patients reduces the severity of organs failure.
In parallel, the investigators will evaluate ex vivo in monocytes from septic patients: redox state and response to inflammatory stimuli; ATP release; metabolic changes and pH; cytokine production; the effects of PPI on these parameters.

研究组 & 干预措施
Esomeprazole
Patients randomized to Esomeprazole Group will receive a bolus of 160 mg of esomeprazole (diluted in 100 ml of 0.9% sodium chloride for intravenous use and administered over 60 minutes) and an intravenous infusion of 12 mg/hr (diluted in 0.9% sodium chloride at a concentration of 8 mg/ml will be injected at a rate of 1.5 ml/hr) for 72 hours .
干预措施: Esomeprazole (Drug)
Placebo
Patients randomized to Placebo Group will receive a bolus of 100 ml of 0.9% sodium chloride for intravenous use administered over 60 minutes with no active principle and an intravenous infusion of 0.9% sodium chloride at a rate of 1.5 ml/hr with no active principle for 72 hours .
干预措施: Placebo (Drug)
结局指标
主要结局
SOFA score reduction
时间窗: Days 1-28
SOFA (sequential organ failure assessment) score is used to track a person's status during the stay in an intensive care unit to determine the extent of a person's organ function or rate of failure. The score is based on six different scores, one each for the respiratory, cardiovascular, hepatic, coagulation, renal and neurological systems which are added up. Each score ranges from 0 to 4. SOFA score ranges from 0 (better outcome) to 24 points (worse outcome).
次要结局
- Antibiotic-free days(Day 28)
- Adjusted ICU-free days(Day 28)
- Mortality(Day 28, 60 and 90)
- Single organ failure severity(Days 1-28)
