Immune Inflammation

В статье рассмотрены вопросы развития фиброза и иммунного воспаления у больных артериальной гипертензией (АГ) с острым ишемическим инсультом (ИИ) в пожилом возрасте. Цель исследования - изучение возраст-ассоциированных особенностей концентрации маркеров фиброза (металлопротеиназы-9, тканевого ингибитора матриксных металлопротеиназ-1, их соотношения ММП-9/ТИМП-1), иммунного воспаления (TNF-α, IL-1β, INF-γ) у больных АГ с ИИ. В исследование были включены 86 больных АГ II степени, из которых 42 человека - среднего возраста (53±5 лет) и 44 - пожилого (66±5 лет), контрольную группу составили 22 пациента пожилого возраста с АГ без ИИ в анамнезе. Критерии включения - пациенты с АГ, поступившие в стационар в остром периоде первого церебрального инсульта. Установлено, что у пожилых больных АГ с ИИ показатели инфламэйджинга и маркеры фиброза были достоверно выше, чем у лиц среднего возраста. Уровень IL-1β был выше на 31,7 % (р<0,01), TNF-α - на 55,7 % (р<0,001), INF-γ - на 36,6 % (р<0,01), уровень ММП-9 - на 46,4 % (р<0,01), ТИМП-1 - на 21,2 % (р<0,01), ММП-9/ТИМП-1 - на 19,6 % (р<0,01) в пожилом возрасте по сравнению с больными среднего возраста с АГ и острым ИИ. Таким образом, установлено, что больные АГ с ИИ имеют нарушения процессов инфламейджинга, синтеза и деградации внеклеточного матрикса, особенно выраженные в пожилом возрасте. The article deals with the development of fibrosis and immune inflammation in patients with arterial hypertension and acute ischemic stroke in old age. The aim of the study was to study age-associated features of the concentration of fibrosis markers (metalloproteinase-9, tissue inhibitor of matrix metalloproteinases-1, their ratio MMP-9/TIMP-1), immune inflammation (TNF-α, IL-1β, INF-γ) in patients with arterial hypertension and ischemic stroke (AI). The study included 86 patients with arterial hypertension (AH) of the 2nd degree, of which 42 were middle-aged (53±5 years) and 44 elderly (66±5 years). The control group consisted of 22 elderly patients with AH without a history of AI. The criteria for inclusion in the study are patients with hypertension who were admitted to the hospital in the acute period of the first cerebral stroke. It was found that in elderly patients with hypertension with AI, the indicators of inflamaging and fibrosis markers were significantly higher than in middle-aged people. The level of IL-1β was 31,7 % higher (p<0,01), TNF-α by 55,7 % (p<0,001), INF-γ by 36,6 % (p<0,01), the level of MMP-9 was 46,4 % higher (p<0,01), TIMP-1 by 21,2 % (p<0,01), MMP-9/TIMP-1 by 19,6 % (p<0,01) in the elderly compared to middle-aged patients with hypertension and acute AI. Thus, it was found that patients with arterial hypertension and ischemic stroke have violations of the processes of inflamaging, synthesis and degradation of the extracellular matrix, especially pronounced in old age.

Post Stroke Depression

Цель исследования - изучение роли цитокинов, соотношения нейтрофилов и лимфоцитов в развитии постинсультной депрессии (ПД) у больных пожилого возраста. В исследование были включены 110 больных с острым ишемическим инсультом, из них 60 человек среднего возраста (52±5 лет) и 50 - пожилого возраста (66±4 года). Контрольную группу составили 20 человек среднего возраста без инсульта в анамнезе. Через 3 мес наблюдения ПД в пожилом возрасте развилась у 28 (56 %) больных, в среднем возрасте - у 26 (43,3 %). Больные пожилого возраста с ишемическим инсультом, у которых развилась ПД, были достоверно старше (7,9 %, р<0,05), чаще имели артериальную гипертензию (12,4 %, р<0,05), уровень гликемии выше на 16,1 % (р<0,05), триглицеридов - на 14 % (р<0,05), ЛПНП - на 12,8 % (р<0,05). Больные среднего возраста с ПД имели ИМТ выше на 8,1 % (р<0,05), уровень гликемии - на 9,6 % (р<0,05), триглицеридов - на 10,9 % (р<0,05), ЛПНП - на 9,7 % (р<0,05), чем больные без депрессии. Пожилые больные с ишемическим инсультом и ПД имели более высокий уровень цитокинов - IL-1β был выше на 35,4 % (р<0,01), TNF-α - на 27 % (р<0,01), INF-γ - на 18 % (р<0,01), чем у больных без ПД. У больных пожилого возраста с ПД соотношение нейтрофилов и лимфоцитов (Н/Л) было на 46 % (p<0,001) выше, чем у больных без ПД. В группе больных пожилого возраста при наличии ПД соотношение Н/Л было на 50 % (p<0,001) выше, чем в аналогичной группе среднего возраста. Таким образом, у пожилых больных с ишемическим инсультом уровень маркеров воспаления может иметь прогностическое значение в развитии постинсультной депрессии. The aim of the study was to study the role of cytokines, the ratio of neutrophils and lymphocytes in the development of post-stroke depression in elderly patients. The study included 110 patients with acute ischemic stroke, including 60 middle-aged people (52±5 years) and 50 elderly people (66±4 years). The control group consisted of 20 middle-aged people without a history of stroke. After 3 months of follow-up, post-stroke depression (PSD) developed in the elderly in 28 patients (56 %), in the middle age in 26 patients (43,3 %). Patients with ischemic stroke in the elderly who developed PSD were significantly older (7,9 %, p<0,05), more often had arterial hypertension (12,4 %, p<0,05), the level of glucose was 16,1 % higher (p<0,05), triglycerides by 14 % (p<0,05), LDL-C by 12,8 % (p<0,05). In middle age, patients with post-stroke depression had a body mass index higher by 8,1 % (p<0,05), a glucose level by 9,6 % (p<0,05), triglycerides by 10,9 % (p<0,05), LDL-C by 9,7 % (p<0,05) than patients without PSD. Elderly patients with ischemic stroke and PSD had higher levels of cytokines - IL-1β was 35,4 % higher (p<0,01), TNF-α by 27 % (p<0,01), INF-γ by 18 % (p<0,01) than in patients without PSD. In elderly patients with PSD, the ratio of neutrophils and lymphocytes (N/L) is 46 % (p<0,001) higher than in patients without PSD. In the elderly, in the presence of PSD, the N/L ratio was 50 % (p<0,001) higher than in the same middle-aged group. Thus, in elderly patients with ischemic stroke, the level of inflammatory markers may have a prognostic value in the development of post-stroke depression.

Objective – to determine the level of anxiety and depression, to investigate cognitive functions and the status of physical activity in patients with hypertension, depending on age.Materials and methods. We examined 67 patients with hypertension I–III stage (atherosclerotic plaque and/or myocardial infarction in history). According to age classification (WHO, 2012) patients were randomized into 3 groups: group I – 25 middle-aged patients, group II – 22 elderly patients, group III – 20 patients of senile age. The highest level of education, the total number of education years; duration of arterial hypertension; anthropometric data and the office blood pressure were assessed. We used an individual approach to determine the target level of blood pressure according to the recommendations ESC/ESH 2018. Cognitive functions were evaluated using the MoCA-test and the Clock Drawing Test. The level of anxiety and depression was determined by the results of the Hospital scale of anxiety and depression.Results. According to the data obtained, a statistically greater degree of depression was recorded among eldery patients in comparison with other groups. Only in this group, a higher level of depression was associated with less time that patients spent for regular exercise during the week. Among middle-aged patients with arterial hypertension, the absence of anxiety and depression was detected in 56.0 %. At the same time, in the group of senile age, 75.0 % of patients were diagnosed with manifestations of anxiety and depression of varying severity. It is important to notice that in the group of senile age the median level of anxiety was higher, although nonsignificantly, in comparison with other groups and met the criteria for subclinical anxiety. Results of multivariate correlation analysis showed that a high level of anxiety in middle-aged patients was associated with an earlier age of arterial hypertension verification, as well as with waist circumference increase and the waist/hip circumference ratio. Among elderly patients, a higher level of anxiety was determined in the presence of physical inactivity and among patients of senile age, an increase in anxiety level was associated with a shorter duration of education and a decrease in cognitive functions. Conclusions. The highest level of depression was diagnosed among people of senile age, which was associated with the presence of physical inactivity. The groups did not differ statistically in level of anxiety, however, an increase in its severity in the middle-aged group was associated with an earlier age of hypertension verification and an increase in the degree of abdominal obesity, among elderly patients – with hypodynamia, and in the group of senile age – with a low level of education and the presence of cognitive dysfunctions.

58 patients with ischemic stroke were examined (29 young people — the main group and 29 middle-aged people — control group). Among the examined young patients, cardio embolic subtype of stroke prevailed (66 %), and among middle-aged patients was observed in 10 %. The athe rothrombotic subtype of stroke prevailed in middle-aged people (69 %), and among young people — 24 %. The lacunar subtype of stroke in young people was 3 %, and in middle-aged people — 21 %. Patients of young had such subtypes of strokes as hemodyna mic and hemorheological, which respectively equaled 3 %. In middle age these subtypes of strokes were not observed among the examined patients. In young people the proportion of vascular pools with ische mic stroke was: vertebrobasilar — 41 %, carotid prevailed to some extend — 59 %. In middle-aged people the proportion of strokes prevailed in the carotid pool — 64 %, in the vertebrobasilar it was 29 %. Middle-aged people also had a “combined stroke” (stroke that occurred in several pools at once), it amounted to 7 %. As a result, Doppler study of cerebral vessels proved that in young people linear velocity in the right middle cerebral artery was authentically higher compared with middle-aged patients. At the same time, the linear velocity in middle-aged patients was statistically greater in the left vertebral artery. Keywords: ischemic stroke subtypes, young age, hemodynamic parameters

In most patients of both groups revealed changes in hemostasis in the direction of increasing the aggregation properties of platelets. However, more pronounced trends in such changes were found in patients with insufficient blood pressure at night. Given the fact that not only in the absence of control over hypertension and failure to achieve target blood pressure levels, but also with different daily blood pressure profiles, there is a high probability of thrombotic complications. That is why it was important for us to find out the peculiarities of the state of platelet aggregation indicators depending on 24 hours day’s profile of blood pressure. To date there are only isolated reports of hemostasis in this category of individuals. We conducted such studies in middle-aged and elderly patients. The aim of the study was to identify the baseline levels of hemostasis indices depending on 24 hours day’s profile of blood pressure in middle-aged and elderly hypertensive patients. Material and methods. We performed the comparative assessment of status of hemostasis in 30 middle-aged (group I) and 30 elderly patients (group II) respectively to clarify this issue in our work. Patients of the surveyed groups were comparable in age, sex and related pathology. Control group consisted of 15 patients for every of the surveyed groups (group III the middle-aged and group IV the elderly respectively) matched with basic by age and gender. Conclusions. Thus, in hypertensive patients there is an increase in platelet activity with age which is more pronounced when stimulating ADP in non-dipper group compared to dipper. In addition in older patients the most significant changes are determined in spontaneous and adrenaline-induced aggregation compared with middle-aged patients.

Background. The urgency of cerebral small vessel disease (cSVD) in modern neurology is considered mainly in terms of the development of vascular dementia and early diagnosis of Alzheimer’s disease. Minimal changes in MRI images and indistinct cognitive disorders in SNAMA-type cSVD (sporadic non-amyloid microangiopathy) last for a long time until they manifest as acute cerebrovascular disorders and/or significant mental deficits. However, clinical and neuroimaging criteria for early diagnosis of the disease have not been established yet, and the nature of the correlations between the indicators of neuropsychological and multiparametric MRI studies has not been clarified. Purpose – to develop criteria for early diagnosis of SNAMA cerebrovascular disease in middle-aged patients using neuropsychological studies and high-field multiparametric MRI. Materials and methods. The study enrolled 34 middle-aged patients (52.5 ± 10.8) with hypertension of stage 1–2, stage I–II and cSVD (women – 11 (32.4%), men – 23 (67.6%)). The control group (19 healthy individuals) was identical in age, gender and total duration of education. MRI (3T) was performed in the following modes: T1-2WI, DWI, 3D Brain FLAIR SHC, 3D tra, VEN BOLD, DTI medium iso SENSE. Neuropsychological studies were performed using the MoSA questionnaire evaluating the EIS, VIS, AIS, LIS, MIS, OIS domains. Results and discussion. We developed and introduced a modified scoring system for determining the severity of the burden of cerebral small vessels disease (BcSVDearly) in clinical practice. Among the early visual MRI markers, the expansion of the perivascular spaces was dominated in 27 (79.4%) of participants. A minor increase in Σ BcSVDearly to 6–7 points was found in 10 (29.4%) patients. The age norm (0–4 points) corresponded to the indicators of Σ BcSVDearly 23 out of 34 (67.6%) in the main group. Additional evidence of the disease was obtained by DTI MRI. The most significant decrease in FA was recorded in belt fibers (Δ: up to – 31.4%) and semioval centers (Δ: up to – 33.6%), the largest increase in MD was recorded in hooked bundles (Δ: up to 24.4%); right prefrontal, orbitofrontal and parietal areas (Δ up to 28.0%). According to the MoSA scale, moderate cognitive impairment was detected in 29 of 34 (85.3%) patients with a significant decrease in scores in the domains of EIS, VIS, LIS and AIS (p <0.001). The severity of early clinical manifestations of cSVD (non-amnestic polydomain moderate disorders of attention, speech, visual-spatial and executive cognitive functions) has been found to be moderately / markedly correlated with THMS, MD (positive) and FA (negative).Conclusions. We determined early visual signs of cSVD associated with arterial hypertension: dilated perivascular spaces, hyperintensity of the periventricular deep white matter of the brain, decrease by 9–33.6% of FA coefficient and increase by 20.8% – 28.0% MD. Moderate correlations between neuropsychological and neuroimaging studies have been demonstrated.

SummaryBackground: Coronary heart disease is the leading cause of death and disability worldwide. Hypertension is a major independent risk factor for the development of CHD. Abnormalities in NO generation or activity have been proposed as a major mechanism of CHD. The purpose of this article is to determine the activity of eNOS and iNOS in patients with isolated CHD and CHD associated with HT of different age groups.Methods: Fifty patients with isolated CHD and 42 patients with CHD associated with HT were enrolled in this study. NOS activity was determined by nitrite anion formed in the reaction.Results: A statistically significant increase in iNOS activity is observed in elderly donors. In patients with isolated coronary heart disease cNOS activity is statistically significantly reduced with respect to the control group. The reduction of enzymatic activity of cNOS is more expressed in elderly patients than in middle-aged patients with coronary heart disease. Alterations in eNOS activity are more expressed in patients with coronary heart disease associated with hypertension than in patients with isolated coronary heart disease. Against the background of cNOS inhibition in the patients, a sharp increase in iNOS activity is observed.Conclusions: It has been shown that disturbance of endo - thelial function in patients with coronary heart disease associated with hypertension is characterized by reduced endothelial NO synthesis by cNOS and increased systemic NO synthesis due to increased iNOS activity. It has been found that the lack of endothelial NO and hyperproduction of »harmful« NO by iNOS are more expressed in elderly patients.

This study was designed to measure changes in blood pressure (BP), urinary catecholamines and ventilatory functions of patients with mild essential hypertension after 10 weeks of Qigong (Shuxinpingxuegong). Fifty-eight patients volunteered to participate in this study and were randomly divided into either a Qigong group (n = 29), or a control group (n = 29). Systolic blood pressure and diastolic blood pressure decreased significantly in the Qigong group such that both became significantly lower after 10 weeks in the Qigong than in the control group. Also, there was a significant reduction of norepinephrine, metanephrine and epinephrine compared to baseline values in the Qigong group. The ventilatory functions, forced vital capacity and forced expiratory volume per sec, were increased in the Qigong group but not the control. These results suggest that Qigong may stabilize the sympathetic nervous system is effective in modulating levels of urinary catecholamines and BP positively, and in improving ventilatory functions in mildly hypertensive middle-aged patients.

Abstract Background Research indicates that abnormal embolism caused by patent foramen ovale (PFO) may play an important role in cryptogenic stroke (CS). However, most researches has focused on young patients, and whether abnormal embolism caused by PFO also plays an important role in elderly CS is uncertain. The purpose of this study is to analyze the clinical characteristics of elderly patients with PFO, and to explore the correlation between elderly PFO and ischemic stroke.Methods 62 elderly patients diagnosed with ischemic stroke admitted to Qilu Hospital of Shandong University from April 2014 to April 2019 were selected as the Test Group. 62 non-stroke patients in our hospital's physical examination center and outpatient clinic were selected as the Control Group. Collect clinical data of patients for retrospective analysis.Results The incidence of PFO in the Test Group was significantly higher than that in the Control Group, the difference was statistically significant (p < 0.05). The proportion of large and medium shunt patients in the Test Group was significantly higher than that in the Control Group (p < 0.05). The proportion of patients with migraine in the PFO (+) group in the Test Group was significantly higher than the stroke patients in the PFO (-) group (p < 0.05).Conclusions The shunt volume of the PFO is related to ischemic stroke and may be a risk factor for ischemic stroke.

Abstract Background There is suggestive evidence that the platelet-to-lymphocyte ratio (PLR) and systemic immune-inflammation index (SII) are related to the severity of fracture. The purpose of this study was to investigate the role of PLR and SII in predicting fracture severity in young and middle-aged patients with tibial plateau fractures (TPFs). Methods The retrospective cohort study involving 229 isolated TPFs was performed between January 2015 and December 2019. Medical records of hospitalized patients were extracted from the electronic case system. Three experienced orthopedic surgeons classified the imaging data according to the Schatzker classification. All the patients were divided into two groups: group1 consisted of fractures of mild to moderate severity (Schatzker types I-IV), and group2 consisted of fractures of severe severity (Schatzker types V-VI). Platelet, neutrophil, and lymphocyte values at admission were obtained. The PLR = platelet/lymphocyte counts and the SII = platelet × neutrophil/lymphocyte counts were noted. Patients in groups 1 and 2 were statistically compared in terms of PLR and SII value on hospital admission. Results There were significant differences in the blood PLR, SII, Na+ and K+ levels, and neutrophil count between the two groups. According to the receiver operating characteristic (ROC) curve, the cut-off of PLR and SII were 157.9 and 923.9, respectively. Our results showed that high PLR and SII were remarkably associated with the severity of TPFs. The sensitivity was 60% and the specificity was 86.9% when using the PLR ≥ 157.9 to predict the severity of the TPFs whereas the sensitivity was 63.3% and the specificity was 74.4% to predict the severity of TPFs at SII ≥ 923.9. In the multivariate analyses, the high preoperative PLR and SII were identified as independent predictors of severe TPFs. Conclusions The PLR and SII are simple and economical biomarkers that can be calculated from routine blood tests and can be used to predict the severity of tibial plateau fractures.
