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
AIM: An analysis of coronavirus infection in Russia and evaluation of different AVT regimens effectiveness. MATERIALS AND METHODS: The study involved a retrospective analysis of 1082 patient records with laboratory-confirmed COVID-19 in 17 regions of Russia. The number of men and women was equal, mean age 48.718.1 (median 50). Patients with moderate COVID-19 (85%) versus mild COVID-19 (15%) were characterized by higher age (median 54 vs 21 years; p0.001), higher body mass index (27.8 vs 23.4; p0.001), prevalence of chronic diseases (75.3% vs 8.5%; p0.001), including circulatory system diseases (37.8%). Moderate COVID-19 characterized higher intoxication (10.86.1 vs 4.22.7 days; p0.001) and catarrhal symptoms duration (10.25.4 vs 6.14.1 days; p0.001). RESULTS: During hospitalization 92% of the patients received AVT, 77% antibiotics, and 16% corticosteroids. Umifenovir therapy resulted in a significant reduction of intoxication (8.75.5 vs 11.75.5 days; p0.001) and catarrhal symptoms duration (8.85.1 vs 12.04.9 days; p0.001) compared to the group without AVT. The usage of INF reduced intoxication symptoms compared with the group without AVT (8.97.5 vs 11.75.5; p0.05). Therapy with hydroxychloroquine, imidazolylethanamide pentandioic acid, and lopinavir + ritonavir combination did not affect the course of COVID-19. Most of adverse reactions were related to antibiotics. CONCLUSION: Umifenovir therapy and inclusion of interferon in AVT regimens was associated improvement in the clinical manifestation of the disease among patients.

ABSTRACT
The international AKTIV register presents a detailed description of out-and inpatients with COVID-19 in the Eurasian region. It was found that hospitalized patients had more comorbidities. In addition, these patients were older and there were more men than among outpatients. Among the traditional risk factors, obesity and hypertension had a significant negative effect on prognosis, which was more significant for patients 60 years of age and older. Among comorbidities, CVDs had the maximum negative effect on prognosis, and this effect was more significant for patients 60 years of age and older. Among other comorbidities, type 2 and 1 diabetes, chronic kidney disease, chronic obstructive pulmonary disease, cancer and anemia had a negative impact on the prognosis. This effect was also more significant (with the exception of type 1 diabetes) for patients 60 years and older. The death risk in patients with COVID-19 depended on the severity and type of multimorbidity. Clusters of diseases typical for deceased patients were identified and their impact on prognosis was determined. The most unfavorable was a cluster of 4 diseases, including hypertension, coronary artery disease, heart failure, and diabetes mellitus. The data obtained should be taken into account when planning measures for prevention (vaccination priority groups), treatment and rehabilitation of COVID-19 survivors.
ABSTRACT
The organizer of the registers “Dynamics analysis of comorbidities in SARS-CoV-2 survivors” (AKTIV) and “Analysis of hospitalizations of comorbid patients infected during the second wave of SARS-CoV-2 outbreak” (AKTIV 2) is the Eurasian Association of Therapists (EAT). Currently, there are no clinical registries in the Eurasian region designed to collect and analyze information on long-term outcomes of COVID-19 survivors with comorbid conditions. The aim of the register is to assess the impact of a novel coronavirus infection on long-term course of chronic non-communicable diseases 3, 6, 12 months after recovery, as well as to obtain information on the effect of comorbidity on the severity of COVID-19. Analysis of hospitalized patients of a possible second wave is planned for register “AKTIV 2”. To achieve this goal, the register will include men and women over 18 years of age diagnosed with COVID-19 who are treated in a hospital or in outpatient basis. The register includes 25 centers in 5 federal districts of the Russian Federation, centers in the Republic of Armenia, the Republic of Kazakhstan, the Republic of Kyrgyzstan, the Republic of Belarus, the Republic of Moldova, and the Republic of Uzbekistan. The estimated capacity of the register is 5400 patients.
ABSTRACT
COVID-19 is a severe infection with high mortality. The concept of the disease has been shaped to a greater extent on the basis of large registers from the USA, Spain, Italy, and China. However, there is no information on the disease characteristics in Caucasian patients. Therefore, we created an international register with the estimated capacity of 5,000 patients - Dynamics Analysis of Comorbidities in SARS-CoV-2 Survivors (AKTIV SARS-CoV-2), which brought together professionals from the Russian Federation, Republic of Armenia, Republic of Kazakhstan, and Kyrgyz Republic. The article presents the first analysis of the register involving 1,003 patients. It was shown that the most significant difference of the Caucasian population was the higher effect of multimorbidity on the mortality risk vs other registers. More pronounced effect on mortality of such diseases as diabetes, obesity, hypertension, chronic kidney disease, and age over 60 years was also revealed. COVID-19 - тяжелое инфекционное заболевание с высоким риском летального исхода. Представление о болезни во многом сформировано на основании крупных регистров, выполненных в США, Испании, Италии, КНР. Однако к настоящему времени нет данных по особенностям протекания болезни у пациентов евроазиатского региона. В связи с этим был создан международный регистр, расчетная мощность которого составляет 5000 пациентов, “Анализ динамики Коморбидных заболеваний у пациенТов, перенесшИх инфицироВание SARS-CoV-2” (AКТИВ SARS-CoV-2), работа в котором объединила специалистов Российской Федерации, Республики Армения, Республики Казахстан и Кыргызской Республики. В статье представлен первый анализ регистра, который включил данные 1003 пациентов. Показано, что самым значимым отличием евроазиатской популяции пациентов оказалось гораздо большее влияние полиморбидности на риск летального исхода в сравнении с другими регистрами, а также более выраженное влияние на риск летального исхода в евроазиатской популяции таких заболеваний, как сахарный диабет, ожирение, артериальная гипертензия, хроническая болезнь почек и возраста старше 60 лет.
ABSTRACT
Most subjects with the COVID-19 experience mild to moderate symptoms, but approximately 10% of cases suffer from severe course of disease. IL-6 inhibitors are actively used to neutralize and prevent the cytokine storm. Olokizumab is a humanized monoclonal antibody belonging to the G4/Kappa immunoglobulin isotype that selectively binds to human IL-6 and effectively neutralizes it. AIM: To evaluate the efficacy and safety of Artlegia (olokizumab) for the treatment of subjects with a disease caused by the SARS-COV-2 virus in a real-world clinical setting. MATERIALS AND METHODS: The analysis included data of 610 subjects aged 55.0812.68 years who received olokizumab at a single dose of 160 mg/mL 0.4 mL subcutaneously as a preemptive anti-inflammatory therapy. The comparison group included 511 subjects aged 55.2311.23 years who received standard therapy without IL-6 inhibitors. Control Endpoints: 1. Positive clinical changes on Day 7. 2. Changes in the CRP levels on Days 1, 2, and 7. 3. Duration of oxygen therapy. 4. Number of days in hospital. 5. Number of adverse events. 6. Disease outcome. RESULTS: If a cytokine storm occurs, immune regulatory events will trigger the development of either a protective immune response or an exacerbated inflammatory response. The use of preemptive anti-inflammatory therapy has both a short-term and, most importantly, a long-term effect on the T and B parts of the immune process. These aspects definitely require further research and observation. CONCLUSION: The use of olokizumab to treat the new COVID-19 coronavirus disease has demonstrated a positive effect on clinical and laboratory parameters. Primarily, it affects the severity of clinical parameters by improving the general condition already on the first day of observation, and decreasing body temperature to normal values. The changes in the C-reactive protein levels show a significant effect of the IL-6 inhibitor on the systemic inflammatory response.

ABSTRACT
The article evaluates the results of Riamilovir use in treatment of patients with a moderate form of the disease caused by a new strain of the SARS-CoV-2 virus. It was found that the average time required to complete resolution of symptoms during treatment with the drug was 6-7 days. The first negative result of PCR analysis for the SARS-CoV-2 virus was registered on the 10-11thday of therapy;two consecutive negative PCR results for the SARS-CoV-2 virus were registered in the majority of patients by day 14-19 of treatment in 63±4.28%. The body temperature of the majority of patients (75%) returned to normal by the 4thday of treatment. CT scan showed improvement in the lungs of patients: a repeated CT scan performed on average on day 19 from the start of therapy showed no lung damage or no progression in 10±3.0% of patients following therapy. The CT scan of the lungs performed in 1-2 months after the treatment showed that the number of patients with no lung damage increased to 27±4.44%. As a result of treatment, a decrease in the C-reactive protein index was observed in patients. The tolerability level of the drug was assessed as good: no adverse events or significant deviations in laboratory parameters were detected.
