Abstract
The study has demonstrated a signifi cant increase in percentage of circulating CD4+CD25hi regulatory T cells and a decrease in Th1 (CD4+IFNγ+ N cells), as well as elevated leukocyte count, neutrophil-tolymphocyte ratio and CRP level during the first 24–48 hours after onset of ischemic stroke (IS). O note, patients with poststroke infection had less pronounced increase in CD4+CD25hi T-cells and the decrease in CD4+IFNγ+ T lymphocytes, while inflammatory response was significantly higher than in the opposite group. The largest difference between groups was observed when assessing the ratio of CD4+IFNγ+ and CD4+CD25hi T cells. The ratio of CD4+IFNγ+/ CD4+CD25hi in patients with infections was 3 times higher than in the group without infectious complications, correlated with the concentration of CRP (R = 0.54; p = 0.02) and the value of ratio > 1.14 allowed to predict infection with a specificity of 85.7% and a sensitivity of 68.8%.
