IL6 and Sepsis: In addition to some of the classic biomarkers, such as CRP and PCT, several recent biomarkers which offer the potential to improve the diagnosis and treatment of sepsis were described: interleukin 6 (IL-6), soluble urokinase plasminogen activator receptor (suPAR), pro-adrenomedullin, presepsin, lipopolysaccharide binding protein, and a soluble triggering receptor expressed on myeloid cells (sTREM) [27].
