| Popis: | Objective: to study the functional characteristics of innate immunity in the formation of postpericardial syndrome (PPS) in patients undergoing coronary artery bypass graft ing (CABG).Materials and methods: the study involved 60 people, 40 of them made up the main group of patients with coronary artery disease, which retrospectively aft er 1 month of observation was divided into 2 groups. Group I CABG and PPS, group II CABG without PPS. The control group consisted of 20 patients without IHD. Before surgery, aft er 5, 14 days and 1 month, the expression of toll-like receptors (TLRs) 2, 4, 9, the content of CD16+ and Granzyme B lymphocytes, the HCT test and serum α-defensin were evaluated in blood cells. Statistical analysis of the results of the study was carried out using the program Statistica 12.0 (StatSoft , USA). The difference in mean values between groups was evaluated by the Mann-Whitney test. Statistical signifi cance was considered signifi cant at p ≤ 0.05.Results: when comparing the initial indices of the main groups and the control group, an increase in the expression of TLRs 2, 4, 9 was revealed. An increase in the content of CD16+, as well as an increase in the cytotoxic activity of natural killers and an increase in the production of α-defensin.Conclusions: on the basis of the study, activation of the cellular link of innate immunity, an increase in the cytotoxic potential of natural killers and a signifi cantly high level of α-defensin both before and aft er CABG were revealed, which can play an important role in the development of PPS. |
