IL6 and infection: Strikingly, alongside established laboratory parameters of infection/inflammation (white blood cell count, C-reactive protein, procalcitonin, interleukin-6), serum (s)KIM-1 concentrations at admission were significantly higher in patients with sepsis than in patients without (191.6 [85.8; 388.9] vs. 132.2 [66.1; 302.3] pg/mL, p = 0.019, Table 1 and Figure 1A).
