Proinflammatory Cytokine IL-17 Shows a Significant Association with Helicobacter pylori Infection and Disease Severity

Figure 1

Comparison of IL-17, IL-23, IL-21, TNF-α, and IL-10 levels (pg/mL) of H. pylori-infected patients and healthy individuals. Expression levels of selected cytokines were compared between H. pylori-infected patients () and healthy controls (). Association of cytokine expression with H. pylori infection was calculated using the Mann–Whitney U test. (a) Comparison of IL-17 concentration among the two groups (). (b) Comparison of IL-23 expression among the two groups (p = 0.0262). (c) Comparison of IL-21 expression (). (d) TNF-α expression levels among H. pylori-infected patients and healthy controls (). (e) Comparison of IL-10 concentration among the two groups ().
