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.
