Levels of interleukins-1β, -2, -6, -8 in the blood of patients with local wounds at various stages of the infectious process

Abstract

Objective. To evaluate the levels of interleukins (IL) -1β, -2, -6, -8 in the blood serum of patients with wounds, depending on the clinical and microbiological characteristics of the wound process.Materials and methods. The evaluation of IL-1ß, IL-2, IL-6, IL-8 indices in the blood serum of 206 patients with wounds was carried out. When analyzing changes in IL, the clinical and microbiological characteristics of the wound process were taken into account.Results. Changes in the levels of IL-1ß, IL-2, IL-6 and IL-8 in the blood of patients with wounds are determined by the duration of the wound process, the presence of clinical signs of inflammation and the presence of microorganisms in the wound. The absence of a systemic response to the presence of potential pathogens (S. aureus) in an acute wound, when IL levels do not exceed 10 pg/ml, can serve as an additional criterion for contamination with minimal wound life (up to 4 days). Preservation of high values of IL-8 from 38.16 pg/ml (33.31; 42.11), no changes in IL-2 (no more than 2.23 pg/ml (1.41; 4.01)) in the blood of patients with wounds which duration exceeds 22 days is a sign of a violation of the healing process and the formation of a chronic wound. The level of IL-6 is recommended as an additional criterion determining the progression of the infectious process in patients with wounds, when an increase in IL-6 values is recorded from 18.79 pg/ml (15.71; 23.01) at critical colonization to 51.65 pg/ml (35.19; 51.95) at the stage of wound infection. IL-6 values of no more than 10 pg/ml indicate the absence of an active inflammatory process.Conclusion. The levels of proinfl ammatory interleukins in the blood of patients can serve as additional laboratory criteria determining the disruption of wound healing and progression of the wound infection process.
