RESUMO
Aim of the study was to evaluate the impact of anti-epidemic measures (CAM) complex on the dynamics of the epidemic process of COVID-19 in a controlled cohort of patients. Material and methods. Patients from 30 social long-term care institutions of the city were included in the study, including neuropsychiatric boarding schools, boarding houses for labor veterans, gerontological centers, and houses for stage veterans. A total of 8303 patients participated in the study, of which 4237 were men (mean age 53.6 years) and 4066 were women (mean age 62.0 years). Vaccination was carried out with Gam-Covid-Vac. Results and discussion. For the entire observation period from March 2020 to August 2021, 1619, cases of COVID-19 or 19.5% of the total number of patients were registered among patients. At the initial epidemic stage (spring-summer 2020), the incidence of COVID-19 among patients was explosive. At the same time, in the autumn-winter period of 2020, an increase in the incidence of COVID-19 was also observed. However, much less pronounced than in April 2020. Despite the progress, it was decided to strengthen the sanitary and anti-epidemic regime in institutions with the introduction of additional preventive measures. One of the most effective long-term algorithms for reducing the infectious disease incidence was vaccination. In this regard, the Moscow Department of Healthcare suggested the need for voluntary vaccination of 100% of patients in all institutions at the beginning of 2021. In the spring of 2021, the number of cases began to increase in the city. The increase in the incidence of COVID-19 was insignificant among the patients of institutions: the maximum number of cases detected in one month during this period was 13 people (in April), or 60.5 times less than in April 2020, and 2.5 times less than in October 2020. The incidence of COVID-19 has become sporadic rather than epidemic. Conclusion. The introduction of CAM in long-term care social institutions in the early stages of the epidemic contributed to a decrease in the incidence of COVID 19. 100% vaccination of patients in combination with other prevention measures reduced the incidence of COVID-19 by more than 28 times. At the same time, it was found that there is a trend of increasing incidence depending on the increase in the level of independent activity of patients.Copyright © 2023 The authors.

RESUMO
Severity of a new coronavirus infection (COVID-19) caused by the SARS-COV-2 virus is largely due to abnormal immune condi-tion in these patients. Lymphopenia is observed in 85% of patients with severe COVID-19 that may be associated with enhanced apoptosis of lymphocytes. Objective. To analyze apoptotic death of lymphocytes and changes in proteins regulating apoptosis in patients with severe COVID-19. Material and methods. We analyzed 93 ICU patients. All patients were divided into three groups depending on severity and outcomes of disease: group 1 consisted of 53 patients with favorable course and outcomes of disease, group 2 included 26 patients with unfavorable course and favorable outcomes of disease, group 3 included 14 patients with unfavorable course and outcomes of disease. Blood sampling for analysis of apoptosis markers was carried out in 5-12 and 14-18 days after clinical manifestation of disease. Quantitative parameters of lymphocyte apoptosis were evaluated using flow cytometry. Regulatory proteins of apop-tosis (phosphorylated AKT, JNK, BAD, BCL-2, p-53, active caspase 8 and 9) were determined on the Luminex platform. We also assessed concentration of leukocytes, relative and absolute lymphocyte count, concentration of C-reactive protein (CRP), procal-citonin and lactate dehydrogenase. Results. Study groups significantly differed in NEWS score (p=0.001), SOFA score (p=0.001), CRP level (p=0.001), severity of lymph-openia (p=0.001) and level of CD14+HLA-DR+ monocytes (p=0.001). Quantitative parameters of lymphocyte apoptosis did not cor-relate with lymphopenia. The highest rates of lymphocyte apoptosis were observed in patients with favorable course and outcomes of disease. There was no correlation between concentration of lymphocytes in venous blood and level of proteins regulating apoptosis. Conclusion. Patients with severe COVID-19 are characterized by abnormal induction of lymphocyte apoptosis through external and internal activation pathways in response to viral aggression. In deceased patients, pro-apoptotic factors prevailed while activity of anti-apoptotic factors was decreased. © 2023, Media Sphera Publishing Group. All rights reserved.
