CXCL8 and bacterial infectious disease with sepsis: In this subset of patients with a measured cytokine response at onset of bacteremia, the proportion of patients with persistent vs. resolving bacteremia significantly differed by Day 1 quartiles of TNF (p < 0.0001) and IL-10 (p = 0.002) measurements; a trend towards significance was observed for Day 1 quartiles of IL-6 (p = 0.10) and IL-8 (p = 0.06).
