ABSTRACT
In April 2020 in order to prevent the spread of the new coronavirus infection COVID-19 on the territory of the Russian Federation, strict quarantine measures were introduced. In the shortest possible time, a large number of general hospitals were repurposed into COVID hospitals, recommendations were issued on the management of patients with a new coronavirus infection based on the existing global experience. The limited resources of the healthcare system in a pandemic require research into the pharmacoeconomic aspects of COVID-19. In the course of the study, a continuous retrospective analysis of the case histories of 6255 patients admitted to the Central Clinical Hospital RZD-Medicine was carried out. During the study period, 22% of patients received biological therapy. The average mortality rate of patients on biological therapy is 11.6%. An individual selection of the therapeutic dose of low molecular weight heparins was carried out, which showed high clinical efficacy. The developed methods were assessed from the perspective of pharmacoeconomics. The increase in the degree of damage to the lung tissue in patients with COVID-19, as well as the presence of concomitant diseases, entails an increase in the cost of treatment. Biotherapy can reduce the cost of treating patients with CT-4 by 16% by reducing the length of stay in the intensive care unit, the need for mechanical ventilation and reducing mortality.Copyright © 2021 Infectious Diseases: News, Opinions, Training.

ABSTRACT
Aim - the discutability of existing scientific publications prompted a retrospective analysis of COVID-19 risk factors among the working population using the example of Russian Railways. Material and methods. Based on the archival documentation of medical institutions of Russian Railways, an analysis of the incidence of employees of the holding was carried out. Data from 2452 cases were analysed, for which full medical documentation was available. The comparison group randomly included 2911 workers who did not have COVID-19, comparable in sex, age, and area of residence. Results. Significant factors of difference between the groups of patients and those who were not ill were: sex, the presence of influenza vaccination, smoking and established diabetes mellitus. There was a trend towards an association of COVID-19 incidence and the presence of cardiovascular disease. In the comparison group, unlike the group of COVID-19 cases, there are 23% more persons who were vaccinated against influenza. In the group of patients with diabetes mellitus was found 3 times more often than in the group of non-patients. In both groups, the incidence rates of cardiovascular disease did not differ. However, as the severity of the disease increased, there was a tendency to increase the incidence of cardiovascular diseases. Meanwhile, the presence of other cardiovascular risk factors (male sex, smoking, diabetes mellitus, obesity) was significantly associated with a higher incidence in the disease group compared to non-patients. Multifactorial analysis also revealed other significant combinations of risk factors with COVID-19 risk: lack of influenza vaccination and the presence of diabetes mellitus;lack of vaccination, smoking and the presence of diabetes mellitus. Conclusion. For the working population, male sex and diabetes may be a significant risk factor for developing COVID-19. Influenza vaccination should be considered as a factor in anti- COVID-19 protection. Cardiovascular diseas e and smoking may serve as additional risk factors.Copyright © 2021 Infectious Diseases: News, Opinions, Training. All rights reserved.

ABSTRACT
The article provides an overview of global trends in various treatment approaches for COVID-19 in terms of pharmacoeconomic effectiveness. Different strategies for managing patients with the new coronavirus infection, separate groups of drugs are considered. The current clinical trials for COVID-19, the main directions, problems and challenges facing the healthcare system are discussed in detail. The aspects of the economic efficiency of various measures to prevent the spread of COVID-19 are presented. A thorough study of the pharmacoeconomic features of the new coronavirus infection will allow to develop effective standards for planning the process of supply for medical organizations in the pandemic.
ABSTRACT
AIM: Assessment of the prevalence and prognostic value of gastroenterological manifestations in patients with COVID-19. MATERIALS AND METHODS: A single-center retrospective cohort study was carried out. Only cases with laboratory confirmed detection of SARS-CoV-2 virus RNA using polymerase chain reaction in oro-/nasopharyngeal smear samples were subject to analysis. Patients with documented (according to anamnestic data and/or according to examination data during hospitalization) organic pathology of the gastrointestinal tract (GIT) and/or hepatobiliary system, malignant neoplasms of any localization, as well as pregnant patients were excluded from the general register of retrospective data. The final cohort was divided into two groups depending on the presence of gastrointestinal symptoms: COVID-19 with gastrointestinal symptoms (cases) and COVID-19 without gastrointestinal symptoms (control). RESULTS: The final sample consisted of 3764 patients, including 2108 (56%) women and 1656 (44%) men. The average age of the subjects included in the analysis was 58.0 years (95% confidence interval CI 48.663.0). In the study cohort, gastroenterological manifestations (alone or in combination) were recorded in 885 (23.51%) patients. Calculation of the odds ratio (OR) of unfavorable and lethal outcomes between the analyzed groups showed that the presence of gastroenterological symptoms significantly increases the chances of lethal outcome in a cohort of elderly and senile patients (OR 1.6817, 95% CI 1.03352.7364; p=0.0364), determines a higher risk of hospitalization or transfer to the intensive care unit (OR 1.2959, 95% CI 1.05471.5922; p=0.0136), development of acute respiratory distress syndrome (OR 1.5952, 95% CI 1.31641.9329; p0.0001), as well as the need for mechanical ventilation (OR 1.2849, 95% CI 1.0771.5329; p=0.0054). CONCLUSION: The present study has demonstrated that gastroenterological symptoms are detected in about one in four patients infected with the SARS-CoV-2 virus and multiply the risk of adverse and life-threatening complications of COVID-19.
