Objective. To study the indicators of hemostasis and fibrinolysis systems, as well as the systemic inflammatory response in patients with newly diagnosed sarcoidosis after infection caused by SARS-CoV-2. Material and methods. A prospective analysis of the indicators of hemostasis and fibrinolysis systems, as well as the systemic inflammatory response of 20 patients with sarcoidosis, after COVID-19, who were on inpatient treatment in Central TB Research Institute. The patients were divided into 2 groups. The first group included 10 patients with sarcoidosis, who had suffered COVID-19 (the main group). The comparison group consisted of 10 patients with sarcoidosis without a history of COVID-19. Results. It was found, that in patients with newly diagnosed sarcoidosis, who underwent COVID-19, there is a hypercoagulation shift in the hemostasis and fibrinolysis system. This was evidenced by a significant shortening of the indicators of APTT, PT and an increase in the level of D-dimer compared to both healthy and patients, who had not undergone COVID-19. In addition, laboratory manifestations of systemic inflammation were most pronounced in patients with sarcoidosis who underwent COVID-19. Probably, changes in the hemostasis and fibrinolysis system occurred within the framework of a systemic inflammatory response.
