Plasma interleukin-18 reflects severity of ulcerative colitis

Figure 1 Correlations between plasma concentrations of IL-18 and values of A: CAI (r = 0. 56, P = 0.02); B: DAI (r = 0.54, P = 0.03); C: endoscopic score (r = 0.62, P = 0.01).

Figure 2 Individual plasma IL-18 concentrations in healthy controls and UC patients with a mild or a severe form of the disease. Statistical significance between severe UC and mild UC as well as a control is indicated by arrows (P<0.05). Horizontal bar denotes the mean IL-18 concentration [pg/mL] in each of studied groups.

Figure 3 Individual mucosal IL-18 concentrations in UC patients with mild or severe form of the disease. Horizontal bar denotes mean IL-18 concentration [pg/mL] in each of studied groups (the difference is not statistically significant).
