Acute Brain Ischemia

Одним из основных требований к разработке экспериментальных моделей цереброваскулярных заболеваний является их максимальная приближенность к реальной клинической практике. В работе систематизированы данные по основным методам моделирования острой ишемии головного мозга (ОИГМ), представлена их классификация, анализируются данные о преимуществах и недостатках той или иной модели. Обсуждаются результаты экспериментальных исследований по изучению патогенеза ОИГМ с использованием различных моделей (полной и неполной глобальной, локальной и мультифокальной ишемии) и способов их реализации (перевязка артерий, клипирование, коагуляция, эмболизация и др.). Особое внимание уделяется «стабильности» последствий острого нарушения мозгового кровообращения: необратимых ишемических повреждений головного мозга или обратимых с реперфузией заданной продолжительности. Отмечается, что важное значение в этих исследованиях должно принадлежать современным методам прижизненной визуализации очагов острого ишемического повреждения, что позволяет оценивать динамику патологического процесса. Предлагаемый метод отвечает требованиям гуманного обращения с животными. Подчеркивается, что выбор релевантной модели ОИГМ определяется задачами предстоящего исследования и технологическими ресурсами научной лаборатории. Development of experimental models for acute forms of cerebrovascular diseases is essential for implementation of methods for their prevention and treatment. One of the principal requirements to such models is their maximum approximation to actual clinical practice. This review systematized major models of acute cerebral ischemia (ACI), their classification, and presented information about their advantages and shortcomings. Also, the review presented results of experimental studies on pathophysiological mechanisms of different types of modeled ACI (complete and incomplete global, local, and multifocal ischemia) and methods for creating these models (arterial ligation, clipping, coagulation, embolization, etc.). Particular attention was paid to “stability” of the consequences of acutely impaired cerebral circulation - an irreversible ischemic brain injury or a reversible injury with reperfusion of a given duration. The authors emphasized that in such studies, a special significance should be given to intravital imaging of acute ischemic damage foci using modern methods, which allow assessing the dynamics of the pathological process and meet the requirements to humane treatment of animals. The choice of a relevant ACI model is determined by objectives of the planned study and the technological resources available at the research laboratory.

Abstract Background In continuous renal replacement therapy (CRRT), administration of anticoagulants is necessary for achieving a certain level of filter lifetime. Generally, anticoagulant doses are controlled to keep activated partial thromboplastin time and other indicators within a certain target range, regardless of the membrane materials used for the filter. However, in actual clinical practice, the filter lifetime varies significantly depending on the membrane material used. The objective of this study was to demonstrate that the minimum anticoagulant dose necessary for prolonging the filter lifetime while reducing the risk of hemorrhagic complications varies depending on the type of membrane. Methods In three beagles, hemodiafiltration was performed with hemofilters using polysulfone (PS), polymethylmethacrylate (PMMA), and AN69ST membranes separately. The minimum dose of nafamostat mesylate (NM) that would allow for 6 h of hemodiafiltration (required dose) was investigated for each membrane material. Results The NM doses required for 6 h of hemodiafiltration were 2 mg/kg/h for the PS membrane, 6 mg/kg/h for the PMMA membrane, and 6 mg/kg/h for the AN69ST membrane. Conclusion For hemodiafiltration performed in beagles, the required NM dose varied for each filter membrane material. Using the optimal anticoagulant dose for each membrane material would allow for safer CRRT performance.

Aim. To study the efficacy and safety of the triple fixed-dose combination (FDC) of amlodipine/indapamide/perindopril on blood pressure (BP) profile in patients with grade I-II hypertension (HTN) in actual clinical practice.Material and methods. Data from 54 patients with paired 24-hour ambulatory BP monitoring (ABPM) data were included in the TRICOLOR subanalysis (ClinicalTrials. gov study ID — NCT03722524). The mean 24-hour, daytime, and nighttime BP were calculated at baseline and after 12-week follow-up. We determined the proportion of patients with nocturnal HTN (≥120/70 mm Hg) and nocturnal hypotension (<100/60 and <90/50 mm Hg) initially and after 12 weeks of triple FDC therapy. Patients with nocturnal BP decrease included dippers (D; 10-20%), reduced dippers (RD; 0-10%) and extreme dippers (ED; >20%), as well as those without nocturnal BP decrease (>0%, non-dipper (ND)). The smoothness index (SI) was analyzed as the ratio of the mean hourly SBP fall to its mean standard deviation in paired ABPM. To assess the BP phenotypes, two methods were used with reference values of <130/80 and <140/90 mm Hg for ABPM and office BP, respectively. Controlled hypertension (CHT), uncontrolled hypertension (UHT), white coat hypertension (WHT) and masked ineffectiveness of antihypertensive therapy were distinguished.Results. Among 1247 participants of the TRICOLOR study, 54 patients with valid paired ABPM were selected (men, 46%; mean age, 57,7 [12,1] years; mean office BP, 150,4 [16,6]/93,3 [10,7] mm Hg; HTN duration, 8,3 [7,5] years). Initially, the mean 24-hour, daytime and nighttime BP was 141,1 [15,4]/85,9 [9,9], 144,2 [15,5]/88,8 [10,5] and 132,6 [18,0]/78,1 [9,9] mm Hg, respectively. After 12-week follow-up, the mean 24-hour, daytime and nighttime BP was 123,1 [10,5]/75,6 [8,5], 125,7 [10,9]/77,9 [8,7] and 115,4 [10,2]/68,6 [8,8] mm Hg, respectively (p<0,001). After 12-week follow-up, the proportion of patients with nocturnal hypertension decreased from 64,8% to 25,0% (2,6 times) (p<0,001). The proportion of NDs and EDs decreased from 16,7% and 7,4% to 5,8% and 0%, respectively (p=0,048); the proportion of patients with RD and D patterns increased from 42,6% and 33,3 to 57,7% and 36,5%, respectively (p=0,048). With triple FDC therapy, the SI during the day was higher than 0,73 in half of the cases. According to the two methods, the proportion of patients with UHT decreased from 81,6% to 4,4%, WHT from 12,2% to 0%. The prevalence of CHT increased from 4,1% to 57,8%, while masked ineffectiveness of antihypertensive therapy — from 2,0% to 37,8%.Conclusion. Twelve-week FDC therapy of amlodipine/indapamide/perindopril led to a significant fall in the mean 24-hour, daytime and nighttime BP values. Comprehensive analysis of two techniques (24-hour and office BP measurement) identified patients requiring further triple FGC titration.
