It is known that in chronic liver diseases, secondary immunodeficiency is formed, which is of great importance for the dental system and the entire body as a whole. Therefore, it becomes clear the importance of studying the state of the protective system of oral tissues in chronic viral liver pathology, which requires timely and constant correction. The aim of this study was to evaluate the activity of proinflammatory cytokines and cytolytic enzymes in patients with chronic viral hepatitis before tooth extraction. The level of cytokine IL-1 in patients with CVI before tooth extraction was on average 43.97±3.56 pg / ml, whereas in healthy people the studied indicator was on average 5.41 ± 0.42 pg / ml. The patients showed an increase in the level of IFN in the blood serum by an average of 6.2 times, the level of interleukin-18, belonging to the IL-1 family, was statistically significantly increased by 2.4 times in patients with CVI, compared with the control group. The features of CVH are dissociations between the levels of proinflammatory cytokines IL-1, IL-6, IL-18 and interferon. This indicates the disintegration of the inflammatory process occurring in the periodontal tissues and with the transition to a chronic course of the disease. Changes in the level of IL-1, IL-6, IL-18 and interferon in the blood serum of patients with CVI from normal parameters before tooth extraction is an indicator of the severity of the inflammatory process in the liver, as evidenced by changes in the dynamics of cytolytic enzymes.
