Summary:
Objective. To evaluate the effectiveness of sequential therapy with Mexidol and Mexidol FORTE 250 in the correction of postcovoid syndrome (PKS) in patients with chronic cerebrovascular diseases (CVD). Material and methods. The analysis of the results of examination and treatment of 110 patients with CVD who underwent COVID-19 was carried out. Patients of the main group (OH, n=55) received Mexidol (5 ml IV drip for 14 days, followed by the transition to the tablet form of Mexidol FORTE 250 1 table 3 times/day for 2 months); 55 patients of the comparison group (GS) did not receive antioxidants. All patients included in the study were conducted MRI examination and extensive neuropsychological testing. Results. There was a significant improvement in the state of cognitive functions, regression of symptoms of asthenia, improvement of night sleep in patients with OG. The differences were statistically significant both in comparison with the baseline level and the HS. Conclusion. The administration of the drug does not require age-related dose adjustment and is well combined with basic therapy. The recommended regimen for the use of Mexidol: 14 days of 5 ml i/v or i/m, then taking the drug Mexidol FORTE 250 at a dose of 1 table 3 times/day for 2 months. Keywords: chronic cerebrovascular diseases, postcovid syndrome, Mexidol, treatment.

Summary:
Objective. To study clinico-psychological profile and life quality of patients with post-COVID syndrome. Material and methods. We examined 162 patients aged 24-60 years with confirmed SARS-CoV‑2 infection which having symptoms that served as the basis for the diagnosis of post-COVID syndrome. Patients underwent general neurological and somatic examination with allocation of the corresponding neurological syndromes. The intensity and quality of pain were assessed using the McGill Pain questionnaire. The level of psychosocial stress was determined by the Holmes-Ray questionnaire, the identification and severity of asthenia — by the MFI-20 asthenia scale. The level of reactive and personal anxiety was studied according to the Spielberger—Khanin questionnaire, depression — according to the Beck scale. The assessment of life quality was carried out using the Russian version of SF-36 questionnaire. To correct the identified disorders, Mexidol was used according to the scheme: 500 mg once daily intravenously for 14 days, followed by Mexidol FORTE 250 750 mg per day orally (250 mg 3 times a day) for 2 months. Results. The course of treatment with Mexidol in patients with post-COVID syndrome led to decrease in the severity of subjective and objective symptoms, asthenic, anxiety and depressive disorders, and improved the life quality of patients. Conclusion. The high efficacy and safety of sequential therapy with Mexidol (injections followed by tablets of Mexidol FORTE 250) has been shown. Keywords: post-COVID syndrome, SARS-CoV‑2 infection, emotional disorders, anxiety, depression, life quality, Mexidol.

Summary:
The development of COVID-19 is associated with damage to various organs and organ systems, including the development of acute ischemic stroke (AI). The article examines modern ideas about the pathogenesis of AI in COVID-19. The data on the choice of optimal therapy for patients with acute AI and COVID-19, as well as on the possibility of improving the effectiveness of rehabilitation measures, are analyzed. Information is provided on the efficacy of the drug Mexidol in patients with AI and COVID-19. Keywords: ischemic stroke, COVID-19, treatment, rehabilitation, Mexidol.

Summary:
The problem of postcovid syndrome (PCS) attracts great interest due to the wide prevalence and variety of clinical manifestations. The main neurological manifestations of PCS are considered. The information about the proposed mechanisms of the formation of PCS is given. The possibility of using the drug Mexidol for the treatment of patients with PCS is discussed.

Summary:
The coronavirus disease COVID-19 is characterized by high mortality and the lack of effective etiotropic therapy. Activation of oxidative stress may be one of the links in the pathogenesis of organ damage of this infection. Objective. To assess the ability of Mexidol® to influence the rate of clinical improvement in pneumonia caused by the SARSCoV-2 virus in hospitalized patients with the novel coronavirus disease COVID-19 and concomitant discirculatory encephalopathy. 62 patients over the age of 18 years with confirmed new coronavirus disease COVID-19 according to computed tomography (CT) of the lungs (stages CT1, CT2, CT3) and PCR of a swab from the nasopharynx and oropharynx for SARS-CoV-2 virus RNA were included. After randomization patients of group 1 received an infusion of Mexidol® at a dose of 1000 mg/day, patients of group 2 – an infusion of isotonic sodium chloride solution for 7 days. Compared with the control group, the patients receiving Mexidol® therapy showed a significantly more pronounced decrease in body temperature, a tendency towards a decrease in the severity of shortness of breath. In the Mexidol® group, the concentration of superoxidedismutase did not change, while in the control group there was a tendency to its decrease, C-reactive protein decreased 2.2 times more than in the control group (p = 0.09). There was a tendency for a more rapid decrease in ferritin in the active intervention group. Mexidol® therapy can have a positive effect on the clinical manifestations and severity of laboratory-inflammatory syndrome in patients with the new coronavirus disease COVID-19. Key words: coronavirus disease COVID-19, oxidative stress, Mexidol.

Summary:
Objective. To study the possibility of improving the efficacy of treatment with mexidol in COVID‑19 patients with chronic cerebral ischemia (CCI). Material and methods. Three hundred and four patients with CCI and COVID‑19 were observed, group 1 (n=152) consisted of patients receiving basic therapy and mexidol, group 2 (n=152) received only basic therapy. Mexidol was administered intravenously for 14 days, 500 mg (10 ml) per 400 ml of saline solution, then Mexidol FORTE 250 was administered in a dose of 250 mg 3 times a day for 2 months. The state of cognitive functions (MoCA scale), sleep (Spiegel questionnaire), asthenia (MFI-20 scale), and quality of life (SIP questionnaire) were evaluated. Examinations were performed before treatment, 30 and 75 days after start of treatment. Results. In group 1, there was a more complete and earlier recovery of the state of cognitive functions (an increase in indicators on the MoCA scale, p<0.01), a regression of asthenia (p<0.05), and normalization of sleep (p<0.01). By the end of the study, there were significantly more patients in group 1 with complete or significant recovery of all quality of life indicators. Conclusion. Long-term sequential therapy with mexidol provides a more complete recovery of impaired functions in patients with CCI and COVID-19. Keywords: COVID-19, SARS-CoV-2, chronic cerebral ischemia, asthenia, cognitive disorders, dementia, quality of life, mexidol.

Summary:
This review focuses on the specific characteristics of COVID-19 disease, which leads not only to respiratory impairments (bronchoalveolar epithelium does not retain oxygen, etc.), but also decreases the level of hemoglobin and its ability to transfer oxygen to the organs and tissues and increases the level of heme, resulting in anoxemia, hypoxia in all organs and tissues, and oxidative stress. Mexidol, a drug developed in Russia, is widely used in clinical practice, including the treatment of diseases accompanied by ischemia and hypoxia. Mexidol has antihypoxic and antioxidant effects, can treat mitochondrial respiratory dysfunction, thereby affecting the key processes in different cells of organs and tissues that develop due to hypoxia. Mexidol can be useful in the comprehensive therapy of patients with COVID-19. Key words: COVID-19, antioxidant, antihypoxant, hemoglobin, hypoxia, Mexidol, mitochondrial dysfunction, oxidative stress.
