We hypothesized that GM-CSF would reduce the occurrence of ICU-acquired infections in immunosuppressed septic patients.
Randomized double-blind trial conducted between 2015 and 2018. Adult patients, admitted to ICU, with severe sepsis or septic shock presenting with sepsis-induced immunosuppression defined by mHLA-DR < 8000 ABC (antibodies bound per cell) at day 3 were included. Patients were randomized to receive GM-CSF 125 μg/m2 or placebo for 5 days at a 1:1 ratio. The primary outcome was the difference in the number of patients presenting≥1 ICU-acquired infection at day 28 or ICU discharge.
The study was prematurely stopped because of insufficient recruitment. A total of 98 patients were included, 54 in the intervention group and 44 in the placebo group. The two groups were similar except for a higher body mass index and McCabe score in the intervention group. No significant difference was observed between groups regarding ICU-acquired infection (11% vs 11%, p = 1.000), 28-day mortality (24% vs 27%,p = 0.900), or the number or localization of the ICU infections.
GM-CSF had no effect on the prevention of ICU-acquired infection in sepsis immunosuppression, but any conclusion is limited by the early termination of the study leading to low number of included patients.
