Aim of this work was to study the content of cytokines in children with chronic gastroduodenitis (CG). The study included 54 patients with CG aged 9–15 years in the period of exacerbation and 16 healthy as the control group. Serum cytokines were measured by ELISA. All children were confi rmed the diagnosis with a biopsy performed fi brogastroduodenoscopy. The level of all the studied proinfl ammatory cytokines (IL-1β, IL-2, TNF-α, If-α) in the period of exacerbation was raised in 4,5–6,1 times. IL-4 levels were within the normal range, which resulted in a sharp increase in the ratio between pro-and anti-infl ammatory cytokines, especially IL-2 to IL-4. In patients with Helicobacter pylori-associated chronic gastroduodenitis reported higher levels of IF-α (147,83 [123,12; 169,45] versus 80,81 [63,14; 95,37] in uninfected patients). There was a direct correlation between the level of antibodies to H. pylori and the concentration of TNF-α (r = +0,41; p < 0,05). Thus, H.pylori stimulates the synthesis of pro-infl ammatory cytokines. Cytokine levels may serve as an informative diagnostic criterion of activity of the pathological process in chronic gastroduodenitis of children.
