DYNAMICS OF SYSTEMIC INFLAMMATORY RESPONSE MARKERS IN PATIENTS WITH URGENT CONDITIONS DEPEND-ING ON THE DEVELOPMENT OF SEPSIS

Background There is still no information on the dynamics of pro- and anti-inflammatory cytokines and mark-ers of the septic process before the clinical manifestation of sepsis. The aim of the study was to analyze the dynamics of inflammation and sepsis markers concentration in early periods in patients with urgent pathology, depending on the subsequently developed sepsis. Materials and methods. The concentration of procalcitonin, C-reactive protein, LBP, IL-6, IL-10, IL-2R in 61 patients with a high risk of sepsis was investigated starting from the first day after admission to the hospital and then with intervals of 3–5 days. The Group 1 included 29 patients with verified sepsis. All patients of this group survived. The Group 2 included 8 patients who died. The Group 3 included 24 patients who had no clinical signs of sepsis. All the patients in this group recovered. Results. We revealed significant differences in concentrations of systemic inflammatory response markers and its dynamics in the period preceding clinical manifestations of sepsis. It was found that it was possible to predict the development of sepsis and its unfavorable outcome with a high statistical probability in the study of paired samples of blood serum of patients received on day 1–3 and 4–6 from the onset of the disease or severe trauma. The predictors were multidirectional changes of IL-6, IL-10, LBP concentrations and more than three-fold IL-2R increase on the background of high concentrations of procalcitonin and C-reactive protein. Conclusion. The highest concentrations of procalcitonin, C-reactive protein, IL-10 and IL-2R were revealed within the first three days in patients who died of sepsis. High concentrations of IL-6 and IL-10 within first three days and different directions of their concentrations during the next 4–6 days indicate the development of sepsis with an unfavorable outcome. Reduction of IL-2R and IL-6 and an increase in IL-10 within the first week after the onset of the disease or trau-ma are predictors of lethal outcome.
