“…Полученная в ЭССЕ-РФ3 бóльшая доля перенесших COVID-19 среди работающей части населения в сравнении с лицами без регулярной занятости, также может быть объяснена с позиции регулярности и широты контактов между людьми. На высокую связь между регулярной трудовой занятостью и серопозитивностью к SARS-CoV-2 указывают и результаты анализа Krieger E, et al (2023), проведенного через год после пандемии в Архангельске: отношение шансов составило 2,0 с 95% доверительным интервалом: 1,5; 2,8 [13]. Однако по нашим данным, частота тяжелого течения COVID-19 у работающих людей, наоборот, меньше: они реже попадали в стационар, чем неработающие (пенсионеры, инвалиды, безработные).…”

Aim. To study the proportion of coronavirus disease 2019 (COVID-19) survivors and hospitalization cases of the Russian population for the period 2020-2022, depending on socio-demographic characteristics.Material and methods. The work was performed on random samples of the population aged 35-74 years from 15 regions participating in the Epidemiology of Cardiovascular Diseases and their Risk Factors in Regions of Russian Federation-3 (ESSE-RF3) study. The examination was carried out from February 2020 to March-April 2022 (n=28718, 47% men).Results. According to a survey of sample participants, the proportion of respondents who had COVID-19 by the spring of 2022 among all surveyed was 26,0%. Among 45-54-year-old respondents, this parameter was maximum (28,0%), while among those aged 65-74-year-old — minimal (22,3%). The following categories of people were more likely to have COVID-19: women (27,9 vs 23,9% of men, p<0,001), persons with higher education (30 vs 22,6% persons without higher education, p<0,001), persons with high income (30,0 vs 24,3% low-income, p=0,002), persons with family (26,6 vs 24,8% single, p<0,001), employed persons (28,4 vs 21,7% non-employed, p<0,001), as well as those living in urban areas (26,5 vs 24,5% country people, p=0,003). But those less likely to have COVID-19 (men, people without higher education, low-income, single, unemployed or rural residents) had more severe disease course. The following categories of people had higher hospitalization rates: men (26,0 vs 20,9% women, p<0,001), patients without higher education (27,1 vs 19,6% those with higher education, p<0,001), non-employed (34,3 vs 18,4% workers), p<0,001) and rural residents (27,2 vs 22,0% of city residents, p<0,001). Hospitalization rate was not associated with the level of income and marital status. However, low-income and single people were more likely to require mechanical ventilation.Conclusion. The results obtained by survey reflect the following population data: the proportion of patients after COVID-19, hospitalization rate and the development of severe acute respiratory failure requiring mechanical ventilation among Russians for the period 2020-2022. This can complement the population data demonstrated by state statistics. Special attention from the healthcare system, both during treatment and prevention of COVID-19, requires males, people aged ≥65 years, low-income people, single people (widowers, divorced), unemployed people (pensioners, disabled people, nonemployed), rural residents and people without higher education.

“…The duration of natural immunity from COVID-19 and its effectivity against new strains are the subject of many investigations for the moment as well as the effectiveness of the vaccination. One way to assess the level of population immunity is to estimate the seroprevalence of anti-SARS-CoV-2 IgG antibodies [4,5]. The following step is to incorporate such information in the model and to simulate the circulation of existing and new strains of SARS-Cov2.…”

“…Since then, several variants of the SARS-CoV-2 virus, such as Delta and Omicron, have been isolated from COVID-19 patients in Russia [ 29 ]. While there are limited data available on the antibody response to SARS-CoV-2 [ 30 ], even less is known about the production of neutralizing antibodies in COVID-19 patients in Russia [ 31 ]. To address this knowledge gap, our study aimed to analyze the humoral immune response in mild, moderate, and severe COVID-19 patients from the Republic of Tatarstan, Russia, with a specific focus on studying neutralizing antibodies.…”

The severity of COVID-19 is a result of the complex interplay between various branches of the immune system. However, our understanding of the role of neutralizing antibodies and the activation of cellular immune response in COVID-19 pathogenesis remains limited. In this study, we investigated neutralizing antibodies in patients with mild, moderate, and severe COVID-19, analyzing their cross-reactivity with the Wuhan and Omicron variants. We also assessed the activation of the immune response by measuring serum cytokines in patients with mild, moderate, and severe COVID-19. Our findings suggest the early activation of neutralizing antibodies in moderate COVID-19 compared to mild cases. We also observed a strong correlation between the cross-reactivity of neutralizing antibodies to the Omicron and Wuhan variants and the severity of the disease. In addition, we found that Th1 lymphocyte activation was present in mild and moderate cases, while inflammasomes and Th17 lymphocytes were activated in severe COVID-19. In conclusion, our data indicate that the early activation of neutralizing antibodies is evident in moderate COVID-19, and there is a strong correlation between the cross-reactivity of neutralizing antibodies and the severity of the disease. Our findings suggest that the Th1 immune response may play a protective role, while inflammasome and Th17 activation may be involved in severe COVID-19.
