Summary:
Alcohol withdrawal arises in result of long-lasting or short, but massive, alcohol abuse, manifests itself with oppressive symptoms and in some cases is complicated by seizures, hallucinosis and delirium tremens that may be life-threatening for patients. The leading neurochemical factors underlying alcohol withdrawal syndrome and its complications are lack of GABA and excessive glutamate activity, which is important for therapy choice. The first-line drugs in the treatment of alcohol withdrawal syndrome and alcoholic delirium are benzodiazepines, which have the maximum pharmacological similarity with ethanol. Other medications, including barbiturates, anticonvulsants, propofol, dexmedetomidine, and antipsychotics, may be used as alternatives to and in addition to benzodiazepines, especially in the case of protracted delirium with therapeutic resistance. Certain prospects in the treatment of alcohol withdrawal syndrome are associated with ethylmethylhydroxypyridine succinate, which is a bit similar to benzodiazepines in its pharmacology.
Keywords: alcohol use disorders, alcohol withdrawal syndrome, alcohol seizures, alcohol hallucinosis, delirium tremens, benzodiazepines.

Summary:
Objective. To study the efficacy and safety of complex treatment with 2-ethyl-3-hydroxy-6-methylpyridine (mexidol forte 250) and venotonic drugs L-lysine aescinat and diosmin/hesperidin in patients with chronic cerebral venous insufficiency (CCVI). Material and methods. One hundred and twenty CCVI patients with clinical and ultrasonic signs of cerebral venous discirculation were studied. Patients were stratified into group 1 (n=40) treated perorally with mexidol forte 250 and diosmin/hesperidin during 74 days in combination with two courses of L-lysine aescinat intravenously on the 1st and 30th days from baseline, group 2 (n=40) treated with mexidol forte 250 and diosmin/hesperidin during 74 days, group 3 (n=40) treated perorally with diosmin/hesperidin during 74 days. Results and conclusion. The efficacy and safety of the complex treatment of CCVI patients with venotonic drugs with the inclusion of mexidol forte 250 at a dose of 750 mg/day for 74 days is shown. The study demonstrates a significant positive effect of mexidol forte 250 on the dynamics of complaints and indicators of the neurological and psychoemotional status of patients. Monotherapy with the venotonic drug diosmin/hesperidin shows its insufficient efficacy. Keywords: chronic cerebral venous insufficiency, antioxidants, mexidol forte 250, venotonic drugs, L-lysine aescinat, diosmin/hesperidin.

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:
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:
Arterial hypertension, diabetes mellitus, obesity and dyslipidemia continue to be the main risk factors for diseases of the circulatory system and the leading causes of mortality in the world, the combination of these diseases significantly increases the likelihood of the development and more rapid progression of cardiovascular and cerebrovascular pathology. Improving approaches to the diagnosis and treatment of these diseases is a priority problem in modern medicine. Currently, there is no universal drug that can influence all stages of pathological process in both cerebrovascular diseases and diabetes mellitus, and the problem of rational use of drugs in patients with comorbid pathology has not been completely resolved. A difficult clinical task includes not only the timely detection of the disease and the correct diagnosis, but also the choice of the safest and most effective medicine. A number of clinical studies have demonstrated the efficacy of mexidol in the treatment of this category of patients, which is determined by its complex, pleiotropic and multimodal mechanisms of action. Keywords: cerebrovascular diseases, diabetes mellitus, metabolic syndrome, antioxidant therapy, mexidol.

Summary:
Aim. To evaluate the efficacy and safety of prolonged sequential therapy with mexidol in the acute and early recovery stages of hemispheric ischemic stroke (IS) across age groups according to the World Health Organization classification. Material and methods. The study is an additional analysis across age groups among patients participated in the randomized double blind multicenter placebo-controlled, in parallel groups trial EPICA. All subjects (62 men and 88 women) were subdivided into age groups: younger than 60 years, 60—65 years, 76—90 years. Additionally, all participants were divided into 2 populations: ITT (Intent to treat population, patients who received at least one treatment/placebo dose) and PP (Per protocol population, patients who received treatment per study protocol). Results of Modified Rankin scale (mRs) at the end of treatment period, Barthel index, Beck depression inventory, European Quality of Life Questionnaire were assessed. Results. The efficacy of mexidol assessed with all the scales did not differ depending on the age group. By the end of treatment, the mean mRS score was lower in the 76-90 years subgroup (in both populations), compared to placebo (p<0,001). The decrease in mean mRS score (Visit 1—5) was more prominent in patients aged 60—65 years (p=0,025), including patients with diabetes mellitus (DM). Patients aged 76—90 years and patients with DM, compared to placebo, had a decrease of the severity of cognitive-affective depression symptoms (p=0,049 and p=0,02) and an increase in patients without problems with everyday activities (p=0,007 and p=0,02). Patients with DM, compared to placebo, also had the higher levels of everyday activity (p=0,023) and quality of life (p=0,045). There were no statistically significant differences in the frequency of side-effects in patients of all groups. Conclusion. It is recommended to include mexidol in therapy of patients with IS in the acute and early rehabilitation stages in all age groups, including patients with DM.
