The aim of the study was to assess the possibility of using indicators of IL-1β, IL-6, IL-8, IL-10, IL-18, TNF-α, PAD-4 and the functional activity of neutrophils in the differential diagnosis of bacteremia caused by gram-negative and gram-positive microorganisms in patients with sepsis.
Results. A case-control study was conducted on the basis of a cohort which included 48 patients with sepsis 30 of whom had a positive blood culture depending on the presence of gram-positive or gram-negative flora in the blood. They were divided into 2 groups. In patients of both groups in the blood on the 1st and 3rd day of the disease, the level of IL-1β, IL-6, IL-8, IL-10, IL-18, TNF-α, PAD4, NET and the functional activity of neutrophils were assessed, were determined. When comparing parameters between groups, IL-10 was higher in patients with gram-negative sepsis, and the ratio of IL-6/IL-10 was lower than in patients with gram-positive sepsis on day 1st of observation.
