ABSTRACT

A prerequisite for effective vaccination is the formation of proper collective immunity in society. The attitudes of healthcare professionals towards vaccination directly impact the population's adherence to this method. Objective. To study the attitude of healthcare professionals toward COVID-19 vaccination. Material and methods. The sociological survey method with the author's questionnaire based on GoogleForm was used. In the sur-vey, 450 physicians aged 25 to 70 participated voluntarily. It was a cross-sectional study carried out in the autumn of 2021. Results. Of those surveyed, the majority (86.8%) of physicians and almost all (96.1%) nurses were vaccinated against COVID-19. When studying the motivation for vaccine prophylaxis, a direct average strength of a statistically significant correlation between the adherence to COVID-19 vaccination and the emergence of a sense of safety was established (rxy =0.346;p<0.05). The most common reasons for the refusal of doctors from vaccination were the fear of complications, beliefs about low protection against infection and the subsequent decrease in immunity. According to healthcare professionals, the most effective means of prevention, in descending order, were a healthy lifestyle, the absence of fear of becoming ill, vaccination, drugs that stimulate immunity, the use of barrier measures, and other means. Conclusion. The ambiguous attitude of healthcare professionals towards vaccination against COVID-19 does exist and deserves the closest attention. Considering the issue's complexity, further research on the attitude of healthcare professionals toward vaccination is required.Copyright © 2023, Media Sphera Publishing Group. All rights reserved.

ABSTRACT

The aim of the work is to form the principles of a personalized approach to the management of patients with COVID-19 with a complicated comorbid background. Material and methods. The article describes a clinical case of successful recovery of an 87-year-old patient from a new coronavirus infection COVID-19, complicated by pneumonia involving 36% of the lung parenchyma area. Along with age, the situation was aggravated by the comorbid status of the patient: the presence of chronic lymphocytic leukemia, hypertension, mechanical prostheses of the mitral and aortic valves, postinfarction cardiosclerosis, paroxysmal atrial fibrillation, type 2 diabetes mellitus, stage 4 CKD, anemic syndrome, and subclinical hypothyroidism. Results. The C-reactive protein level at admission was 114.46 mg/L. The patient refused hospitalization. Baricitinib 4 mg, favipiravir according to the scheme, vitamin D 2000 units were prescribed for the previously taken therapy. Already after 3 days, C-reactive protein decreased by 4.6 times, and by the 8th day by 15.5 times and amounted to 7.38 mg/ml. The temperature returned to normal on day 2 from the start of baricitinib. In dynamics, a decrease in creatinine level to 177.0 mumol/l was noted, the glomerular filtration rate increased to 30 ml/min/1.73 m2, which corresponded to stage 3b of CKD (a pronounced decrease in glomerular filtration rate). Conclusion. Despite the age of the patient, many comorbidities, each of which could be fatal, the timely use of baricitinib on an outpatient basis made it possible to stop the progressive course of the disease.Copyright © Eco-Vector, 2023.

ABSTRACT

Organ transplant recipients are at a high risk of infection with high hospitalization rate, critical rate and fatality, due to low immune function caused by taking immunosuppressants for a period of long time after organ transplantation. Currently, vaccination is recognized as an effective approach to prevent infection. Organ transplant recipients may be vaccinated according to individual conditions. However, the sensitivity to vaccines may decline in organ transplant recipients. The types, methods and timing of vaccination have constantly been the hot spots of clinical trials. In this article, the general principles, specific vaccines and SARS-CoV-2 vaccines of vaccination in organ transplant recipients were briefly reviewed, aiming to provide reference for the vaccination of organ transplant recipients. Moreover, current status of SARS-CoV-2 vaccination for organ transplant recipients was illustrated under the global outbreak of novel coronavirus pneumonia pandemic.Copyright © 2022 Journal of Zhongshan University.

ABSTRACT

[Background] The COVID-19 pandemic hints at the importance of modernizing disease control system. To understand the scientific research strength of our country's disease control system in recent years is conducive to formulating more targeted policies or measures to promote the modernization of the disease control system. [Objective] To understand the scientific research strength and research hotspots of China's provincial-level centers for disease control and prevention (CDCs) from 2011 to 2020, and provide evidence for the development of scientific research work, discipline construction, and talent team construction in CDCs in the future. [Methods] The Science Citation Index Expanded (SCIE) and Social Science Citation Index (SSCI) of the Web of Science Core Collection were used to retrieve SCI-indexed English papers published by 31 provincial CDCs (excluding Taiwan Province, Hong Kong and Macau Special Administrative Regions) in our country from 2011 to 2020, and to screen literature with provincial CDCs as the first affiliation for bibliometric analysis and visual analysis. Bibliometric analysis included the SCI-indexed publications of different provincial CDCs (as co-affiliation and the first affiliation), the number of SCI-indexed papers published by provincial CDCs (as the first affiliation) and funding rates by years, the high-frequency authors of SCI-indexed papers published by provincial CDCs (as the first affiliation) and their distribution, and the characteristics of the journals. Visual analysis software Citespace 5.8.R1 was used to draw keyword co-occurrence maps, cluster information tables, and emergence maps to provide information on research hotspots and their evolution. [Results] From 2011 to 2020, the number of SCI-indexed papers from 31 provincial CDCs was 8 420 (including co-affiliation), of which 2 060 papers listed provincial CDCs as the first affiliation. The provincial CDCs of Zhejiang, Jiangsu, Shanghai, Beijing, Shandong, and Guangdong were the leading six institutes in terms of the total number of SCI-indexed papers contributed as co-affiliation or the first affiliation. There was a large gap in the total number of SCI-indexed papers among the provincial CDCs. The highest total number of SCI-indexed papers contributed by provincial CDCs as the first affiliation was Zhejiang CDC (448 papers), while the lowest number was Xinjiang CDC (only 1 paper). From 2011 to 2020, the total number of SCI-indexed papers contributed by the 31 provincial CDCs as the first affiliation showed an overall increasing trend. Except for 2011, which was 63.1%, the funding rates in other years exceeded 70%. In terms of high-frequency authors, 13 first authors published >=10 SCI-indexed papers: Zhang Yingxiu from Shandong CDC had the highest number of SCI-indexed papers (47), followed by Hu Yu from Zhejiang CDC. Zhejiang, Jiangsu, Beijing, Guangdong, Shanghai, and Shandong still ranked the top six of >=4 first authored-SCI papers. In terms of journal characteristics, the top 20 journals with the highest number of SCI papers published a total of 862 papers, accounting for 41.8% (862/2 060), and PLOS ONE ranked the first (188 papers). The research hotspots were mainly concentrated in the fields of infection, child health, and epidemiology. The main keywords of the first three cluster categories were related to the research fields of adolescent overweight and obesity, HIV, and vaccine immunity. The results of keyword emergence showed that research hotspots shifted from overweight, obesity, and body mass index to antibodies, vaccines/vaccination, and cohorts. [Conclusion] The past ten years have witnessed increasing numbers of SCI-indexed papers published by provincial CDCs in our country and a stubbornly high funding rate. However, the gap among the provincial CDCs is still large seeing that economically developed eastern provincial CDCs published more SCI-indexed papers. Research hotspots have gradually shifted from overweight, obesity, and body mass index to antibodies, vaccines/vaccination, and cohorts.Copyright © 022 Shanghai Municipal Center for Disease Control and Prevention.

ABSTRACT

Introduction: Coronavirus disease 2019 (COVID-19) has caused thousands of deaths since it was declared as a pandemic. Recently it continues to be one of the most followed topics in the world in terms of its course and treatment. Favipiravir is a broad-spectrum anti-viral agent that has been shown to be effective against various Coronaviruses in vitro. However, as with any drug use, side effects may develop with the use of favipravir treatment. Case Report: We reported a 55-year-old female patient with acute urticarial with angioedema whom had COVID-19 pneumonia. She had no history of allergy, atopy, previous similar episodes or family history of hereditary angioedema. There is no drug or food consumption that may be suspicious in terms of allergy described by the patient other than favipravir. Conclusion(s): As far as we know, it is the first case reported from our country. Since there is no specific examination for differential diagnosis, we cannot distinguish as a rare side effect due to favipiravir treatment or COVID-19 cutaneous manifestation. As a result, studies involving more cases of COVID-19 skin findings are needed.© Copyright 2020 by Emergency Physicians Association of Turkey.

ABSTRACT

Coronavirus disease-19 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become a global pandemic and is giving rise to a serious health threat globally. SARS-CoV-2 infection ranges from asymptomatic carrier state to severe illness requiring intensive care unit (ICU) management. It is postulated that with COVID-19 infection, children are less prone to develop severe symptoms as compared with adults. The data on immunocompromised children affected with COVID-19 infection is limited and not many publications are there on the effects of 2nd wave of COVID-19 infection in pediatric hematology/oncology patients till date. In our experience during second wave, 17 patients were found to be positive for SARS-CoV-2 with a male: female ratio of 2.4: 1 and median age of 8 years (range 1-18 years). Out of these 17 patients, 10 (58.8%) patients required hospital admission whereas the remaining were managed at home. Only 1 patient required ventilatory support and there was no mortality. Though the number of pediatric patients with COVID-19 infection were more during the second wave but majority had mild to moderate symptoms and were easily managed.Copyright © 2022 Pediatric Hematology Oncology Chapter of Indian Academy of Pediatrics

ABSTRACT

Remdesivir (GS-5734) is a new direct-acting antiviral drug in the nucleotide analogue class with antiviral activity against SARS-CoV-2 and the ability to inhibit RNA-dependent RNA polymerase. Preliminary results from phase III randomized clinical trials of remdesivir are inconsistent. Understanding the fact of the limited world experience with the use of remdesivir in COVID-19 required further study of its efficacy and safety in real clinical practice. The aim of the study is to evaluate the efficacy and safety of remdesivir in the treatment of patients with COVID-19. Material and methods. The study included 1422 patients with a novel coronavirus infection (COVID-19) who received remdesivir as part of complex therapy in a hospital setting at medical organizations of the Moscow public health system. Additionally, standard therapy was carried out, regulated by the Interim Guidelines "Prevention, Diagnosis and Treatment of Novel Coronavirus Infection (COVID-19)" of the Ministry of Healthcare of the Russian Federation, the current version. The efficacy of the drug was assessed based on primary and secondary efficacy points. Primary variable: 1) cumulative incidence of clinical outcomes in patients with COVID-19 treated with remdesivir as part of complex therapy;2) median time to clinical improvement according to the World Health Organization ordinal categorical scale (under clinical improvement, the patient is assumed to move >2 categories towards improvement in clinical condition). Secondary variables: 1) median time to achieve <2 NEWS scores lasting at least 24 hours or hospital discharge;2) mortality from all causes;3) duration of fever (>38 degreeC), days;4) duration of hospitalization, days;5) time to achieve elimination of the pathogen from the upper respiratory tract (no SARS-CoV-2 RNA), days. The safety of remdesivir was assessed based on the registration of adverse events using the method of spontaneous reports. Results. The analysis of clinical outcomes of treatment showed that 1195 (84.1%) patients recovered, death from all causes occurred in 227 (15.9%) patients. The median improvement in clinical status on the World Health Organization ordinal categorical scale was 6 days. The median time to reach a NEWS score of <2, lasting at least 24 hours, or hospital discharge was 4 days. The median duration of fever was 3 days from the start of remdesivir administration. The median length of hospital stays for patients included in the Register was 9 days. Adverse reactions associated with the use of remdesivir were recorded in 11 (0.7%) patients. Serious adverse reactions were not registered. During hospitalization, all adverse reactions were resolved. Conclusion. A retrospective analysis of data from the Registry of 1422 patients with COVID-19 who received remdesivir as part of complex therapy in medical organizations of the state healthcare system of Moscow in routine clinical practice showed clinical efficacy and a favorable safety profile of remdesivir (Remdeform, lyophilizate for solution for intravenous administration 100 mg, manufactured by JSC Pharmasyntez, Russia). The data obtained are consistent with previous randomized clinical trials of remdesivir and allow us to recommend its further use in patients with COVID-19 as part of complex therapy.Copyright © The Author(s), 2022.

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

Patients with end-stage kidney disease undergoing hemodialysis have one of the highest COVID-19 mortality rates. The use of innovative methods capable of optimizing their treatment outcomes is important for clinical practice. Aims - to investigate the efficacy and safety of neutralizing monoclonal antibodies in COVID-19 patients treated with hemodialysis. Material and methods. We conducted a retrospective controlled single-center study with 102 COVID-19 patients on maintenance hemodialysis involved (M: 67;65.7%;W: 35;34.3%), aged 57.2+/-15.3 years. PCR-detected SARS-CoV-2 infection was diagnosed in all patients. Neutralizing monoclonal antibodies were administered to 69 patients, who formed the study group (group 1). The control group included 33 patients (group 2). The combination of bamlanevimab and etesevimab was the most frequent therapy used (in 59 patients). Results. In the course of the disease, group 1 patients, compared to those of group 2, had statistically significantly higher blood oxygen saturation values (94.2+/-5.7 vs 89.8+/-10.7);they required less frequent oxygen support (29.0 vs 54.5%) and ICU treatment (18.8 vs 48.5%), respectively. Fatal outcomes occurred in 4 (5.8%) of 69 patients who received neutralizing antibodies and in 6 (18.2%) of 33 patients who did not receive the therapy, p<0.05. Except for one patient, all other patients in both groups developed an unfavorable outcome due to progressive lung damage. However, only 4 of 6 (2/3) patients with progressive lung damage died in group 1, whereas the similar course of the disease proved fatal in all cases in group 2. Conclusion. The use of neutralizing monoclonal antibodies in hemodialysis patients is safe and effective when the drugs are administered early, the pulmonary process progression is insignificant and dominant SARSCoV-2 variants are sensitive to them.Copyright © 2022 Tomsk Polytechnic University, Publishing House.

ABSTRACT

Aim. An online survey among social network users was conducted to assess the frequency of COVID-19 cases, the spectrum of medications used for treatment, and the subjective assessment of clinical manifestations of the disease. Material and methods. An anonymous online survey was conducted among users of various social networks using a questionnaire created on the SurveyMonkey survey and research platform. During the first month of December 2021, the survey included 23 questions regarding the clinical and demographic characteristics of respondents, the number of COVID-19 cases, clinical manifestations, and severity, as well as the need for medical help and medication. Results. 752 respondents took part in the online survey, more than 70% of them are under 50 years old. Among the respondents 59.73% had a new coronavirus infection (COVID-19). More than 40% of the participants had COVID-19 in the period from September 2020 to April 2021 (2nd wave in Russia). In 79.2% of people, the presence of a new coronavirus infection was confirmed by one of the diagnostic methods: polymerase chain reaction (PCR test), radiography, the presence of antibodies to Ig G/M, and took into account the presence of contact with infected SARS-CoV-2. 411 participants observed any clinical manifestations of the disease. Most often respondents who had COVID-19 indicated weakness, cough, dyspnea, disappearance or decrease in the acuity of smell and taste. The volume of lung tissue damage in 36.5% of cases was less than 25%. The disappearance of any clinical manifestations of the disease immediately after recovery was noted by 32.0% of respondents. Most of the patients (59.2%) sought medical help at the polyclinic, 38.9% had to self-medicate. 71.9% respondents indicated they had been vaccinated against COVID-19, but without specifying the timing and completeness of the course. Side effects after immunization (fever, weakness, soreness, and redness at the injection site) were subjectively assessed by 41.9% of respondents. Conclusion. Among the surveyed respondents, 62.7% of the disease symptoms were mild. The highest number of cases occurred in the 2nd and 4th waves of COVID-19 morbidity in Russia. Most often respondents indicated symptoms of acute respiratory infection. The complete disappearance of clinical manifestations of the disease immediately after recovery was noted by 32.0 % of respondents, and the persistence of symptoms for up to a year - 7.5. More than 70% of the participants in the online survey reported vaccination against COVID-19, but the questionnaire did not include questions about the timing of vaccinations (before or after COVID-19) and the completeness of the course.Copyright © Eco-Vector, 2023.

ABSTRACT

Aim of study. To evaluate the influence exerted by additional use of a fixed combination of folic acid with pyridoxine hydrochloride and cyanocobalamin in complex therapy for hospitalised patients with COVID-19-associated lung damage on parameters of inflammation and clinical outcomes. Material and methods. A comparative prospective interventional study included 117 patients with a lung lesion volume caused by the SARS-CoV-2 coronavi-rus corresponding to CT-1 and CT-2. The study group included 78 patients who additionally received a fixed combination of 5mg folic acid, 4mg pyridoxine hydrochloride, and 6mug cyanocobalamin three times a day in combination with standard therapy. The comparison group included 39 patients. Results. By days 14-21 of hospitalisation, the main group showed a decrease in the proportion of patients with CT symptoms of "cobblestone appearance" by 26% (p = 0.005) and an increase in the proportion of patients with transformation of viral lung lesions into areas of consolidation of the pulmonary parenchyma by 23% (p <0.001). The effect of a fixed combination of folic acid with vitamins B6, B12 on the achievement of the level of C-reactive protein <20 mg / l by day 7 depending on the red blood parameters and the number of platelets was established (likelihood ratio test in the logistic regression model: 13.925;P = 0.084) as well as the shortening of the time period required to reach the first negative result of the SARS-CoV-2 RNA test (in the linear regression model, R = 0.437;R2 = 0.191;F = 4.552;p = 0.006). Conclusion. The use of a fixed combination of folic acid with vitamins B6, B12 for patients with COVID-19 is associated with earlier achievement of positive dynamics in CT symptoms of lung damage. The additional use of these micronutrients in combination with restoration of red blood count and platelet count improves the odds ratio of an early decrease in serum C-reactive protein, negative result of the SARS-CoV-2 RNA test.Copyright © 2021, Krasnoyarsk State Medical University.

ABSTRACT

The course of a new coronavirus infection is associated with immune system disorders during the acute stage of the desease. Administration of effective etiotropic drugs contributes to early elimination of the virus. At the same time, risks of post-COVID immune system disorders are minimized. The aim of the study was to investigate features of the immune response formation against the background of etiotropic therapy in patients who underwent COVID-19. Material and methods. An observational retrospective comparative study was conducted. The study involved patients with COVID-19 3 months after treatment with etiotropic drugs (riamilovir or umifenovir). The study involved 87 patients (52 women and 35 men) with varying degrees of COVID-19 severity. In accordance with the study design, participants were divided into 2 groups: the first group - 41 patients (received riamilovir during the acute period of the disease);the second group - 46 patients (received umifenovir in the acute period of the disease). Statistical processing of the results was carried out using the Statistica 8.0 software package. Extensive indicators, median (Me) and interquarter range Q25-Q75 were calculated. Statistical significance between the indicators of independent samples was assessed by Mann-Whitney nonparametric test and Chi-square test. P-values below 0.05 were considered statistically significant. Results and discussion. Analysis of clinical and laboratory data showed that after suffering COVID-19, not all indicators of the immune system in patients who had had COVID-19 recovered to control values. However, it is noted that in patients of the main group, which using riamilovir, compared to the comparison group was less likely to be diagnosed with chronic systemic syndrome, inflammation, dysregulation of the cellular link of immunity in the early post-COVID period.Copyright © Eco-Vector, 2022.

ABSTRACT

Post-covid syndrome is characterized by a spectrum of persistent symptoms that do not disappear for many months, which may be due to an inadequate immune system response. This leads to a discussion of potentially new methods immunorehabilitation with the use of effective enterosorbents. The aim of the study was to assess the clinical effectiveness of enterosorbents and immunological parameters of patients with a long-term "post-covid syndrome" who have undergone a new coronavirus infection COVID-19. In n pilot monitored open non-randomized experimental clinical observationanl study 33 patients who had a novel coronavirus infection with COVID-19 underwent comprehensive treatment with the inclusion of azoximer bromide (Polyoxidonium) and colloidal silicon dioxide (Polisorb MP). Analysis of clinical and laboratory data showed that after immunorehabilitation, most of the indicators characterizing the state of the immune system in patients who had COVID-19 were restored to control values. And the use of enterosorbents in complex immunorehabilitation therapy is justified and confirmed by the relief of dyspeptic and asthetovegetative syndromes, which makes it possible to recommend it for use in complex treatment.Copyright © 2021 Infectious Diseases: News, Opinions, Training.

ABSTRACT

The problem of COVID-19 vaccination in patients with autoimmune inflammatory rheumatic diseases is discussed. There is an increased risk of viral infections in these patients. Attending physicians should provide patients with rheumatic diseases with complete information about the risks and benefits of COVID-19 immunoprophylaxis. The use of immunosuppressive drugs, rather than the diseases themselves, can reduce the level of post-vaccination immune response. This requires choosing the optimal time for carrying out COVID-19 vaccination in this group of patients. Fragments of European and American recommendations on vaccination against COVID-19 in patients with rheumatic diseases are given.Copyright © 2022 Infectious Diseases: News, Opinions, Training.

ABSTRACT

Objective: assessment of the efficacy and safety of the use of anticoagulant, glucocorticosteroid, metabolic therapy in patients with COVID-19 at the inpatient stage of treatment. Material and methods. In February 2021, a prospective, randomized, single-center, continuous comparative study was organized on the basis of the Gomel City Clinical Hospital No. 3, which included 827 patients with moderate and severe clinical course of COVID-19. Results. Stratification of the risks of an unfavorable outcome in patients with moderate and severe clinical course of COVID-19 made it possible to optimize treatment, with the selection of optimal doses of anticoagulant and glucocorticosteroid therapy, which led to an increase in patient survival. A high level of blood lactate reflects the degree of damage to the lung tissue, the severity of the course of the disease and requires an increase in the dose of anticoagulant therapy. The use of thiotriazoline effectively reduces the level of lactate, which makes it possible to restore the energy balance of the cell. Conclusion. The use of therapeutic (intermediate) doses of anticoagulant and optimal glucorticosteroid therapy in patients at high risk of poor outcomes with moderate and severe clinical course of COVID-19, can increase the survival rate from 82.1 to 96.8%, p<0.0001. The appointment of anticoagulant therapy was complicated by "minor" bleeding in 2.13% in the main group, in 2.11% in the control group, p>0.05, and the use of glucocorticosteroids was complicated by newly diagnosed diabetes mellitus (2.13% in the main group, 1.81% in the control group, p>0.05), which allows us to consider the therapy used is safe. The use of the metabolic, antioxidant agent thiotriazoline in patients with an LDH level of more than 800 U/L and with a high risk of an unfavorable outcome led to a decrease in LDH within five days of treatment by 447.9 U/L in the main group compared with the control group by 124.0 U/L (p=0.0001), which was accompanied by an improvement in the general condition, increased physical activity, and an earlier start of rehabilitation.Copyright © 2022 by the authors.

ABSTRACT

Introduction: The clinical outcomes of COVID-19 infection in children with cancer have been variable worldwide. Therefore, we aimed to collect data from all regions in India through a national collaborative study and identify factors that cause mortality directly related to COVID-19 infection. Method(s): Data was collected prospectively on children across India on cancer therapy and diagnosed with COVID-19 infections from 47 centers from April 2020 to October 2021. Information was recorded on the demographics, the number of children that required intervention, and the outcome of the infection. In addition, we analyzed the impact of the delta variant in 2021. Result(s): A total of 659 children were studied, of whom 64% were male and 36% were female. The data from the eastern region was sparse, and this was a collection bias. COVID-19 infection was predominantly seen in children less than five years. The delta variant had a higher impact in the southern region, and this was statistically significant. Of the 659 children, 30 children died (4.5%), however only 7 of the deaths were directly attributed to COVID-19 infection (1%). Conclusion(s): The study reports the largest nationally representative cohort of children with cancer and COVID-19 to date in India. We identified demographic and clinical factors associated with increased all-cause mortality in patients with cancer. Complete characterization of the cohort has provided further insights into the effects of COVID-19 on cancer outcomes. The low mortality allows us to recommend that specific cancer treatments be continued without delays in therapy.Copyright © 2022

ABSTRACT

The purpose of this review is to analyze the data of scientific articles on medicines indicated as etiotropic and approved for outpatient use within the framework of temporary methodological recommendations for the prevention, diagnosis and treatment of a new coronavirus infection in the Russian Federation. Material and methods. A systematic search of literature was carried out on the databases MEDLINE, PubMed, Cochrane Library, GHL, OpenGrey, ICTRP and ClinicalTrials.gov until April 2021. 37 779 articles were indexed in the ScienceDirect database (keywords: SARS-CoV-2), of which (pre-press) - 2023 (2), 2022 (69), published in 2021 (19 642 articles), in 2020 (12,966 articles). The search was carried out using the following keywords: Favipiravir - 1622 publications, Umifenovir - 387 publications, which indicates a high interest in the problem of new coronavirus infection in general and its drug (etiotropic) therapy, in particular. Results. The conducted analysis demonstrates that drugs based on favipiravir have a larger number of studies proving its effectiveness in different clinical groups of patients with COVID-19, while it is important to note the breadth of the geography of published works, which allows us to speak about the reproducibility of the results. Drugs from this group have a direct antiviral effect with the studied target of action (i.e., most likely, the principle of etiotropic therapy is implemented). Conclusion. The search for new drugs, as well as the expansion of information about the mechanisms of action of previously known molecules, is the basis for the development of COVID-19 therapy regimens with maximum efficiency and safety.Copyright © 2021 Sovero Press Publishing House.
