ABSTRACT
Effectiveness of the inclusion of reamberin in the complex rehabilitation of patients suffering of pneumonia caused by SARS-CoV-2 was evaluated at the outpatient stage. The data of 162 patients who received the rehabilitation treatment including, in addition to pharmacological benefits, exercise therapy and vacuum labile massage, were analyzed. In addition, patients of the main group (n = 82) received reamberin (1.5%, intravenously in a volume of 500 mL) for 10 days. The biochemical parameters of blood were studied in dynamics, and the blood oxygenation was monitored by the Stange and Genchi tests and the pulse oximetry. The quality of life was assessed in terms of the SF-36 questionnaire. The inclusion of reamberin in the complex rehabilitation contributed to improvement of the main biochemical parameters of blood (the levels of aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyl transpeptidase decreased 1.2, 1.7, and 1.9 times, respectively, p0.5) and caused a more pronounced increase in the external respiration function (on the average by 8.4 sec according to the Stange test and by 9.1 sec according to the Genchi test), which was accompanied by positive trends in the quality of life indicators (according to the SF-36 questionnaire) in terms of physical functioning (by 5.1 points) and general health status (by 3.76 points. The obtained clinical and laboratory data, together with good tolerance of the drug, allow us to recommend the inclusion of reamberin in rehabilitation regimens for patients with pneumonia caused by SARS-CoV-2.

ABSTRACT
The aim of the study was to evaluate the effectiveness of including remaxol in the medical rehabilitation of elderly and senior patients with COVID-19-associated pneumonia and changes in liver enzyme activity. Material and methods: 116 patients (56 men and 60 women) were examined. All patients underwent a complex of medical rehabilitation on an outpatient basis on the 10–12th day after discharge from the hospital and in the presence of 2 negative results of PCR tests for SARS-CoV-2, which included, in addition to the recommended measures (drug therapy and exercise therapy), vacuum labile massage according to the author's methodology and a course of hepatoprotective drugs. Depending on the latter, the patients were divided into two groups: I — the main group (n=60) — received remaxol in the drug treatment regimen: 400 ml, intravenously, drip, in a course of 10 days, II – comparison (n=56) — ademetionine: 400 ml, intravenously, drip, in 0.9% saline, in a course 10 days. Before rehabilitation and at its end, the following tests were carried out: Stange and Genchi tests;quality of life was assessed using the SF-36 questionnaire. Laboratory studies included determination of the following indicators levels: ALT, AST, their ratio, alkaline phosphatase, GGT, total and direct bilirubin, LDH, albumin and total protein levels. Results. The inclusion of hepatoprotectors in the medical rehabilitation of the patients of this group contributes to a decrease in cytolytic and cholestatic syndromes, which is more pronounced in patients who received remaxol: (a decrease in AST by 1.5 times (from 35.4±1.4 to 23.5±l), and ALT — by 1.8 times (from 38.7±1.3 to 21.5±0.4 IU/l), as well as normalization of bilirubin metabolism: a decrease of total bilirubin by 2.1 times (from 32.1± 0.6 to 14.8±0.9 µmol/l) and of direct — by 2.5 times (from 7.1±0.6 to 2.8±0.1 µmol/l). A pronounced increase in resistance to hypoxia was noted during the therapy with the drug (according to Stange and Genche), which contributed to an improvement in psychophysiological indicators of patients’ quality of life (according to the SF-36 questionnaire). The obtained results, along with the safety of the drug, allow us to recommend its use in patients with this pathology.
ABSTRACT
The Bioethics Committee of Belarus and the local ethics committee of the St. Petersburg Pasteur Institute approved the study. Selection of participants was carried out using a questionnaire method and online technology (internet, cloud server). Volunteers were randomized into seven age groups (years of age): 1–17;18–29;30–39;40–49;50–59;60–69;and 70+. Regional randomization ensured proportional representation of volunteers from each region, and no more than 30 people were included from one enterprise. In accordance with manufacturer instructions, blood plasma samples were analyzed for: IgG antibodies (Abs) to the SARS-CoV-2 nucleocapsid (Nc) using a quantitative ELISA test system;and IgG Abs to the receptor binding domain (RBD) of the SARS-CoV-2 S (spike) surface glycoprotein using a qualitative ELISA test system. Statistical processing was carried out using Excel 2010 and other software. Statistical differences were designated as significant when p < 0.05, unless otherwise indicated. Results. The level of seroprevalence, in terms of Abs to Nc among the Belarusian population, was 38.4% (95% CI 37.6–45.4). The highest Ab levels were found among individuals in older age groups (50-70+ years old). The lowest were found in children 1–17 years old and in young people 18–39 years old The distribution of seroprevalence across Belarusian regions was relatively homogeneous, with the exception of the Minsk Region, where a statistically significant decrease in the indicator was noted. In terms of profession, the largest share of seropositive individuals was found among transportation workers;the smallest was found in business. The moderate COVID-19 incidence has not led to a dramatic increase in the number of contacts. The base reproduction number (R0) was 1.3. In the Republic of Belarus, there was a moderate level of asymptomatic COVID-19 among seropositive individuals (45.3% [95% CI 44.0–46.7]). This form of infection was observed most often among children aged 1–17 years old (65.0% [95% CI 61.3–68.6]). In parallel with seroprevalence assessment, SARS-CoV-2 vaccination was carried out. We used two vaccines: Gam-COVID-Vac (also known as Sputnik V, developed by Gamaleya National Center for Epidemiology and Microbiology, Russia);and BBIBP-CorV (Sinopharm, PRC). Vaccination against SARS-CoV-2 was accompanied by an increase in the level of anti-RBD Abs (95% [95% CI 94.7–96.7]). Taking into account the vaccination of a subset of the population with BBIBP-CorV, the overall herd immunity, inferred from the analyzed indicators (presence of anti-Nc or anti-RBD Abs), was 47.1% (95% CI 46.3–48.0). Conclusion. COVID-19 in Belarus was characterized by a moderately pronounced course of the epidemic process. The threshold level of herd immunity to SARS-CoV-2 has not yet been reached, as a result of which the conditions for progression of the epidemic remain.
