In the group of patients with hepatitis in the course of EBV infection, there was a negative correlation between s-ICAM-1 level and IL-6 level (ρ = −0.464, p < 0.001) and a positive correlation between TNF-α concentration and the number of leukocytes (ρ = 0.336, p = 0.013), lymphocytes (ρ = 0.281, p = 0.039), monocytes (ρ = 0.322, p = 0.018), and IL-6 concentration (ρ = 0.408, p = 0.002) (Figure 3). Here, IL6 is linked to hepatitis A virus infection.
