Abstrakt: Aim: To study the relationship between the state of the respiratory burst of neutrophils and the indices of hemostasis in patients with ischemic (IS) and hemorrhagic (HS) strokes.
Material and Methods: Thirty-three patients with IS and 31 patients with HS were examined in the first 24 hours after an acute cerebrovascular accident (ACA). The diagnosis of ASA was confirmed by neuroimaging methods: computed tomography and magnetic resonance imaging. The determination of the respiratory burst state of blood neutrophils was carried out using chemiluminescence analysis. Indicators of vascular-platelet and coagulation hemostasis were determined in all patients.
Results and Conclusion: There were changes in the kinetics and activity of neutrophil respiratory burst in stroke patients. Patients with HS had higher (compared to those of patients with IS) level of spontaneous and induced synthesis of secondary ROS but with a decrease in metabolic resources for their synthesis. Activation of spontaneous and ADP-induced platelet aggregation was detected only in HS. Patients with HS had a higher level of fibrinolytic activity as compared to the patients with IS. There were positive correlations between the kinetic parameters of blood coagulation and the synthesis of primary ROS by neutrophils in patients with HS, whereas the intensity of all ROS synthesis negatively correlated with activated partial thromboplastin time. Therefore, in patients with HS the synergistic relationship between the respiratory burst of neutrophils (pro-inflammatory activity) and coagulation hemostasis was more pronounced compared to patients with IS.
