[Dynamics of proinflammatory cytokine in biological therapy of inflammatory bowel disease].

Chronic inflammation in IBD is accompanied by an imbalance in the production of TX1 and Th2 cytokines. Imbalance of cytokine profile is important pathogenetic value at chronic inflammatory process, since the formation of a defective immune response to pathogenic agent promotes recurrence of the disease. Analysis of the dynamics of proinflammatory cytokines allows to estimate the activity of the inflammatory process, and effectiveness of the therapy. Increased levels of proinflammatory cytokines: TNF-alpha, IFN-gamma, IL-2, IL-5, IL-8, IL-12, IL-15 in serum of patients with IBD, indicating their possible involvement in the mechanisms of development of CD and UC. The increase in the content of these cytokines was accompanied by increased activity of disease that can be used to diagnose IBD activity.
