摘要:The aim of this study was to identify inflammation-associated markers during the early phase of sepsis in rhesus macaque. Four rhesus macaques were given an in-travenous dose of 1010 CFU/kg of E. coli. Blood samples were collected before, or 30 minutes, 2, 4, 6 and 8 hours after E. coli infusion. Physiological parameters, bac-teremia, endotoxemia, C-reactive protein (CRP), procalcitonin (PCT), and plasma cy-tokines/chemokines were determined for each animal. Bacteremia was present in all animals from 30 minutes to 3 hours after E. coli infusion whereas endotoxin was de-tected during the full-time course. CRP and PCT levels remained at detectable levels during the whole experimental window suggesting an ongoing inflammatory process. Signature cytokines and chemokines such as TNF-α, MIP-1α, and MIP-1β peaked about 2 hours after E. coli infusion and decreased thereafter. Plasma IL-6, IL-12p40, IFN-γ, and IL-1Ra, as well as I-TAC, MIG, IP-10 and MCP-1, remained at detectable levels after 4 hours of E. coli infusion. This nonhuman primate model could be useful for the assessment of new therapeutics aiming to suppress key inflammatory markers throughout sepsis early phases.
