Monocyte phenotype, their phagocytic capacity as well as the cytokine production from 10 patients with sepsis with low interleukin-6 (IL-6) serum concentrations (<1000 pg/mL) and 8 patients with sepsis with high IL-6 (1000 pg/mL) plasma concentrations were investigated within 24 hours of fulfilling the criteria for sepsis. Monocytes from patients with high IL-6 levels had higher levels of human leukocyte antigen (HLA)-DR, HLA-ABC, CD64, and CD71, and the production of tumor necrosis factor-alpha (TNF-alpha) and IL-8, as well as the capacity of monocytes to phagocytose, was significantly elevated. Of 8 patients with high levels of plasma IL-6, 4 patients died. In contrast, all 10 patients with low plasma IL-6 concentrations survived until day 28. Patients who died had constant high IL-6 concentrations during the first 3 days, whereas IL-6 levels in patients who survived decreased by 88%. Our data indicate that IL-6 levels are a better prognostic parameter in the early phase of sepsis than the monocyte HLA-DR expression.
