Summary:
The aim of the study. To study the peculiarities of responding to stress, the stress resistance and adaptation of older men and women with chronic brain ischemia, as well as the stressboard effect of Mexidol. Material and methods. 124 patients aged 60–74 years old are surveyed: 72 men and 52 women (average age, respectively, 65.3 ± 0.4 and 64.7 ± 0.7 years) with Chronic Brain Ischemia I–II stage against the background of arterial hypertension and its combinations with atherosclerosis of cerebral vessels. The level of psychosocial stress was determined on the Holmes-Ray scale. Features of the response of patients to stress was studied using the methodology Scale of Psychological Stress PSM‑25 and S. Rogenzweig. Stress resistance was investigated using S. Kuhlen's stress resistance self-resistant test and Villianson. The level of anxiety was determined using a scale of Ch. D. Spilberger and Yu. L. Khanin, depressed – backup questionnaire. The type of adaptation reactions was studied in the leukocyte blood formula on the percentage ratio of lymphocytes and segmented neutrophils, taking into account the representation of other formed elements. Results. The level of stress in older women with Chronic Brain Ischemia was higher than in men. The predominance of the intrinsic orientation of the reaction to stress and resolving the type of response to men, and the extrapunitive or self-defense type among women, which may indicate the largerness of the latter. The level of stress resistance was lower in women than in men, which correlated with higher indicators of situational anxiety. Adverse adaptation reactions were more often registered in women than in men. The course of treatment with Mexidol of elderly patients with chemical leads to a decrease in the severity of subjective and objective symptoms, alarming disorders, increases the stress resistance and adaptive capabilities of the body, which is confirmed by an increase in the number of persons with favorable adaptation reactions. The high efficiency and safety of sequential therapy with Mexidol (injections, then the tableted form of Mexidol Forte 250) is shown.

Summary:
Objective. To study the effect of Mexidol on the functional state of myocardium, NT-proBNP level, exercise tolerance, quality of life, severity of oxidative stress, inflammatory response and endothelial dysfunction in patients with chronic brain ischemia and chronic heart failure NYHA class II-III in a 13-week sequential (intravenous and oral) therapy with Mexidol® and standard therapy. Material and methods. The study included 44 patients with chronic brain ischemia and chronic heart failure NYHA class II—III. Mean age was 65.5±11.8 years, men accounted 75%. The group of Mexidol + standard therapy of chronic heart failure included 21 patients, the group of standard therapy — 23 patients. Echocardiography parameters, exercise tolerance test (six minute walk test, SMWT), patient’s clinical condition according to SHOKS scale (modification by V. Yu. Mareev), NT-proBNP concentration, markers of oxidative stress (malonic dialdehyde (MDA), superoxide dismutase (SOD)), inflammatory reaction (C-reactive protein (CRP), tumor necrosis factor α (TNFα)), homocysteine and cystatin C were examined initially, after 7 days and 13 weeks. The quality of life was assessed initially and at the end of the study using the Minnesota Living With Heart Failure Questionnaire (MLHFQ) and the Kansas City Cardiomyopathy Questionnaire (KCCQ). Results. «Mexidol + standard therapy» group was characterized by more significant improvement in the quality of life, better SMWT data and SHOKS scores, significant decrease in end-diastolic and end systolic LV dimensions, as well as NT-proBNP level after 7 days and 13 weeks compared to the basic therapy group. Mexidol administration reduced MDA concentration and increased SOD activity after 7 days and 13 weeks. We also observed a significant decrease in CRP and TNFα levels after 7 days and 13 weeks in the same group. Less augmentation of homocysteine was revealed in the Mexidol therapy group. There were no significant between-group differences in cystatin C levels. Conclusion. Mexidol in addition to standard therapy of chronic brain ischemia and chronic heart failure class II-III has a favorable effect on the quality of life, functional status, improves clinical condition and intracardiac circulation, decreases concentration of NT-proBNP, promotes antioxidant activity, reduces inflammatory reaction, slows down increase of homocysteine and does not influence kidney function.

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:
Vascular cognitive impairment (VCI) is one of the most serious problems of clinical neurology, being the second most common cause of dementia. VCI covers a range of disorders in which vascular factors cause or contribute to cognitive decline. Among the main risk factors for VCI are old age and vascular factors, which lead to endothelial dysfunction and damage, which, in turn, can cause neurovascular dysfunction, increased permeability of the blood-brain barrier, and microvascular thrombosis. Oxidative stress is one of the most important mechanisms for the development of VCI that indicates the need for the use of agents with antioxidant activity. One of these drugs is ethylmethylhydroxypyridine succinate (mexidol). Mexidol is a drug with marked antioxidant and antihypoxic activities. The clinical efficacy of mexidol in relation to VCI has been demonstrated in many studies. Keywords: chronic cerebrovascular insufficiency, oxidative stress, vascular cognitive impairment, endothelial dysfunction, mexidol.

Summary:
The aim of the study was to assess the efficacy, safety and possibility of correcting the neuropsychiatric manifestations of chronic cerebral ischemia (CCI) by Mexidol® on the background of arterial hypertension (AH), atherosclerosis (IHD), osteoarthritis (OA) or rheumatoid arthritis (RA). Material and methods. We examined 134 patients 45–75 years old with neurovizualized CCI, combined with hypertension, coronary artery disease, and joints pathology. Group 1 (observation) included 79 patients – 30 patients with RA (subgroup 1А) and 49 patients with OA of knee joints (subgroup 1B), who got Mexidol® in their complex therapy. Group 2 (control) consisted of 30 patients – 25 patients with RA (subgroup 2A) and patients with OA (subgroup 2B), who got basic therapy without Mexidol® addition. The dynamics of subjective and physical symptoms, values on the CGI, MoCA, MFI 20 scales, anxiety and depression scales of Hamilton and Tinnetti were estimated. Mexidol® was administered intravenously (500 mg per day) for 14 days, followed by oral administration of Mexidol® FORTE 250 by 250 mg 3 times/day for another 60 days. Results. On the background of constant standard complex therapy, an increasing improvement was revealed in all studied indexes in cases of additional use of Mexidol®. In control groups, the cognitive status did not change. The use of initiating intravenous therapy with Mexidol® increased the adherence of patients to long-term use of the drug. Conclusion. Locomotor dysfunctions in polymorbid patients are partially associated with CCI. The additional appointment of sequential infusion and tablet forms of Mexidol® significantly improves cognitive functions with the correction of walking stability, asthenic manifestations, and increases motivation for active life. Key words: chronic cerebral ischemia, Mexidol®, osteoarthritis, rheumatoid arthritis, arterial hypertension, ischemic heart disease.
