In the group of patients with bacterial and fungal infections, IL-8 showed a steady increase in the presence of bacteria with higher median values of 11,980 pg/mL and 27,000 pg/mL on days two and three compared to 5220 pg/mL and 1180 pg/mL in patients with no superinfection, p = 0.93 and p = 0.05, respectively Figure 3.
