Background. Differentiation syndrome (DS) is a potentially fatal complication of therapy for acute promyelocytic leukemia (APL) with an incidence of up to 48 %. To date, no reliable DS risk factors have been found, with the exception of leukocytosis at the APL onset.Aim. To determine the risk factors associated with DS in patients with APL during induction therapy with arsenic trioxide (ATO) and tretinoin (ATRA).Materials and methods. The study included 39 patients with APL, 29 (74.4 %) of them were classified as low-risk according to ELN (European Leukemia Net), 10 (25.6 %) were classified as high-risk. At the disease onset, cytological and molecular (chimeric transcript PML::RARα, FLT3-ITD mutation) bone marrow studies were performed, the expression of 28 differentiation antigens by blood and bone marrow blast cells was determined (markers of early precursors, myeloid and lymphoid differentiation, cell adhesion molecules, chemokine receptors, integrins, selectin), body mass index (BMI) and the leukocytes number dynamics during induction course were assessed. All patients received ATRA and ATO therapy. Patients from the high-risk group at the onset received 1–3 injections of idarubicin (12 mg/m2) and dexamethasone (8–10 mg/m2 2 times a day) to prevent DS until leukocytosis reduced. In cases of DS, dexamethasone was prescribed at a dose of 10 mg/m2 2 times a day; in cases of severe DS, the induction course was interrupted.Results. Of the 39 patients, 12 (30.8 %) were diagnosed with DS: 20 % of high-risk patients (2/10) and 34.5 % of low-risk patients (10/29). There was no statistically significant association of leukocytosis more than 10 × 109 /L at onset, microgranular morphology of blast cells, bcr3-variant PML::RARα, FLT3-ITD mutation with DS. In multivariate analysis, the probability of DS was associated with BMI ≥30 kg/m2 and mean fluorescence intensity of CD38 antigen by blast cells, regardless of risk group. based on the results of the ROC-analysis, the threshold value of mean CD38 fluorescence intensity was set at 25,000 cu, if exceeded, DS is highly likely to develop.Conclusion. the high incidence of DS among low-risk patients is probably due to the lack of prophylactic glucocorticosteroids administration for the development of leukocytosis during ATRA and ATO therapy. BMI ≥30 kg/m2 and mean CD38 fluorescence intensity more than 25,000 cu were identified as statistically significant DS risk factors.

Aim. To study the glomerular filtration rate (GFR) dynamics calculated by creatinine and cystatin C during induction immunochemotherapy in patients with newly diagnosed diffuse large B-cell lymphoma in order to objectify the method for estimation.Materials and methods. The open longitudinal study included 39 patients with newly diagnosed diffuse large B-cell lymphoma who received specialized treatment at the Oncohematology Department of National Medical Research Centre for Oncology (Rostov-on-Don) in 2021. Patients received induction immunochemotherapy according to the R-CHOP regimen (rituximab, doxorubicin, cyclophosphamide, vincristine, and prednisolone) in combination with accompanying therapy (allopurinol 300 mg/day). Blood sampling was carried out at 0, 24, 48, 72, 120 hours and on 21st day of the 1st therapy cycle. Patients were divided into 2 groups depending on the GFR level, calculated by creatinine, before treatment: group A – 27 (69 %) patients with GFR >90 ml/min/1.73 m2, group B – 12 (31 %) patients with GFR <90 ml/min/1.73 m2.Results. During the immunochemotherapy in patients with initially reduced GFR, a further decrease was observed with the restoration of the initial level by day 21 of therapy. When calculating GFR by cystatin C, in contrast to the calculation by creatinine, it revealed the dependence of GFR level on pathological process stage: GFR in group A patients with stages I–II is 20.4 % lower than in patients with stages III–IV, in group B – by 30.5 %. The use of the fisher test at GFR thresholds of 90 and 60 ml/min/1.73 m2 revealed a greater advantage in establishing absolute GFR levels, especially in the range of 60 to 90 ml/min/1.73 m2.Conclusion. The data obtained confirm that the determination of GFR by cystatin C in patients with diffuse large B-cell lymphoma is a more sensitive method that objectively reflects the functional state of the kidneys, especially when values are within the “gray area” – from 90 to 60 ml/min/1.73 m2.

HighlightsThe article presents data on international practices regarding simultaneous coronary bypass surgery and esophagectomy. There are very few works devoted to this topic in the literature, whereas such patients can show up unexpectedly but cannot safely undergo multiple procedures. Studying the international practices will allow specialists to make the right decision in each individual case. AbstractCoronary heart disease (CHD) remains the leading cause of death from cardiovascular disease, accounting for nearly 50% of deaths. However, recent data show a significant change in the composition of patients with CHD: patients with a concomitant diagnosis of esophageal cancer, a disease for which a new generation of novel immune and targeted therapies has altered and significantly increased life expectancy, predominate. However, the treatment algorithm for such patients is not fully known. If myocardial revascularization is performed first, radical surgery regarding the tumor will be delayed. If first to perform surgical intervention on the esophagus, then the number of complications increases, which according to some authors is 30–40 times higher than in patients without cardiac disease. One-stage intervention and simultaneous surgery allows to avoid such problems. This article summarizes the world experience of such interventions.

HighlightsWe present a clinical case of a patient with atrial fibrillation and a high bleeding risk according to HAS-BLED bleeding risk score who underwent thoracoscopic left atrial appendage (LAA) occluder implantation due to lack of endovascular access. Thoracoscopic amputation of LAA also can be performed in cases where an endovascular access cannot be achieved due to occlusion of the inferior vena cava or thrombosis of LAA. However, it is necessary to monitor the condition of the stump when conducting thoracoscopic amputation of LAA, and stop anticoagulation therapy only in case of non-embologenic stump. AbstractAtrial fibrillation is the most common rhythm disorder that can be conservatively treated using antiarrhythmic therapy, and anticoagulants can be used to prevent thromboembolic complications. However, prolonged use of anticoagulants is complicated by the risk of bleeding. Left atrial appendage (LAA) occluder implantation is an alternative way of preventing of thromboembolic and hemorrhagic complications. The article presents a clinical case of thoracoscopic LAA amputation after unsuccessful endovascular LAA occluder implantation in the patient with the inferior vena cava occlusion.

Highlights The severity of pneumonia and the presence of cardiovascular diseases have a negative impact on the physical aspect of quality of life. Women`s quality of life indicators tend to be worse than men`s. Regular work activity is a factor that improves the physical aspect of the quality of life. AbstractAim. To analyze the relationship between the quality of life (QoL) and the psychological and somatic state of patients 3 months after Coronavirus disease 2019 (COVID-19) pneumonia.Methods. The study is a part of the “Prospective Follow-up Study of Patients after COVID-19 Pneumonia” that involves data on 351 patients (age 53±11) 3 months after hospitalization. Women accounted for 51% of all patients. Cardiologist and clinical psychologist examined cardiovascular and psychological health of patients. We assessed QoL by using the SF-36 survey, and psychometric properties by using the GAD-7, PHQ-9 and PSS-10. We estimated the severity of the COVID-19 using the discharge summaries information.Results. The prevalence of stress symptoms (27,4% vs 5,1%, p = 0,030) and depression (18,00 [13,00–25,00] vs 20,00 [15,00–24,00], p = 0,032) were higher in patients with cardiovascular disorders. Moreover, QoL was lower in this group of patients in all subscales except for “Mental health” and “Mental health aspect”. Women were more 3 times more likely to experience psychological and emotional disorders compared to men (29,1% vs 16,2%, ОR = 2,615 95%; 95% CI 1,695–4,035; p<0,001). At the same time, all QoL indicators in women were significantly lower. For example, the average score on subscales “Mental health aspect” was equal to 47,17 [41,33–51,35] in women and 50,16 [46,65–52,35] in men (p<0,001), and the average score on subscale “Physical health aspect” was equal to 66,32 [60,71–72,62] in women and 63,82 [56,04–70,93] in men (p = 0,003). The QoL scores on physical health subscales were higher in patients with mild and moderate lung lesions. Scores on the “Social functioning” subscale were higher in unmarried patients (87,00 [62,50–100,00] in married patients and 100,00 [75,10–100,00] in unmarried patients; p = 0,017), and scores on the subscale “Physical health aspect” were lower in unemployed patients (48,73 [44,43–52,31] in employed patients and 44,84 [41,32–49,73] in unemployed patients; p<0,001).Conclusion. Тhe presence of cardiovascular disorders and severity of the COVID-19 pneumonia affected the physical aspect of QoL. QoL in women is worse compared with men. Regular work activity improves the physical aspect of QoL. There is a decrease in social activity in married patients after COVID-19 compared to unmarried patients.

HighlightsThe review analyzed the role of various preoperative indicators as predictors of long-term mortality in patients with myocardial infarction and coronary microvascular obstruction (no-reflow) that developed during percutaneous coronary intervention. As a result of a multifactorial analysis, taking into account the confounders available for evaluation, we have found that predilation serves as an independent predictor of death within two years. AbstractAim. To evaluate the role of various aspects of percutaneous coronary interventions (PCI) as predictors of long-term death in myocardial infarction (MI) and coronary microvascular obstruction (CMVO, no-reflow).Methods. The unmatched case-control study included 232 patients with type 1 MI and CMVO developed during PCI. CMVO criteria were as follows: TIMI flow grade <3, Myocardial blush grade <2, ST segment resolution after PCI <70%. The “cases” group consisted of 54 (23.3%) patients who died within the next two years, the “controls” group consisted of 178 (76.7%) patients who survived. The analysis included the following indicators: predilation, high-pressure balloon post-dilation, vacuum assisted manual thromboaspiration, intra-aortic balloon pump, intracoronary administration of isosorbide dinitrate and verapamil hydrochloride, glycoprotein IIb/IIIa inhibitors and “potent” p2y12 inhibitors usage, bare-metal stents, stent implantation with exceeded rated burst pressure, 3 or more stents usage, PCI on more than one artery, the ratio of contrast agent volume to glomerular filtration rate (GFR) >3.0. A univariate comparative analysis of the groups regarding PCI aspects and potential confounders was performed (Mann-Whitney, Fisher). To control the confounders, a multivariate analysis was carried out (logistic regression).Results. Differences were obtained for the following indicators: “predilation” – in 51 (94%) patients in the “cases” group and in 139 (78%) in the “control” group, p-value = 0.005; “intra-aortic balloon pump” – in 9 (17%) and 7 (4%) patients respectively, p-value = 0.003; “the ratio of contrast agent volume to GFR >3.0” – in 26 (48%) and 48 (27%) patients, p-value = 0.005. Multivariate analysis revealed that only predilation was an independent predictor of death within two years – odds ratio 7.38 (95% confidence interval 1.70–49.04, p-value = 0.005).Conclusion. Predilation of the infarct-related coronary artery is an independent predictor of death within two years in MI patients who develop CMVO during PCI.

HighlightsPatients with stable coronary artery disease, borderline coronary artery stenoses (BCAS) and increased thickness of epicardial adipose tissue (EAT) are characterized by development of cardiovascular diseases (CVD) at a younger age and higher levels of proinflammatory markers compared to patients without increased thickness of EAT (in case of comparable obesity class, diabetes type, angina grade and apolipoprotein B levels). Aim. To study the features of the course of stable coronary artery disease with borderline coronary artery stenoses (BCAS) depending on the epicardial fat thickness.Methods. 201 patients with stable angina of 1–3 grade with BCAS (50–70%) were included in the study. The 1st group consisted of 57 (28,4%) patients with high EAT levels, the 2nd group consisted of 144 (71,6%) patients without normal EAT levels. The results of biochemical blood tests and systemic inflammation markers (high-sensitivity C-reactive protein, IL 1, 6, 8, 10, TNF-a, cystatin С, MMP-9, NTproBNP) concentration were evaluated. The epicardial fat thickness was determined by echocardiography. All patients underwent coronary angiography.Results. The general EAT thickness was at 6.00 [5.00; 6.50] mm in the 1st group and at 3.00 [2.30; 4.00] mm in the 2nd group (p<0.001). Hypertension (p<0.001), CAD (p<0.001), and myocardial infarction in particular (p = 0.003) were detected at a younger age in the 1st group. There were no significant differences in terms of prevalence of obesity, diabetes mellitus, angina grade and type of prescribed medication. Patients in the 1st group showed higher levels of NTproBNP (p = 0.002) and hsCRP (p = 0.027). Moreover, patients in the 1st group had a higher Apo-A1 levels (p = 0.023) and a lower Apo B/Apo-A1 ratio (p = 0.019). Proinflammatory cytokine levels were comparable, however anti-inflammatory cytokine IL-10 levels (р =0.005) and the frequency of elevated IL-10 levels (p<0.001) were lower in the 1st group. Higher cystatin C levels and the frequency of elevated cystatin C levels (p<0.001) were observed more often in patients with high EAT levels.Conclusion. Patients with stable CAD, borderline coronary artery stenoses and high EAT levels can be characterized by cardiovascular diseases detected at a younger age and higher levels of proinflammatory markers compared with patients with normal EAT levels in case of comparable obesity class, diabetes mellitus, angina grade, and Apo B levels.

HighlightsThe appointment of omega-3 polyunsaturated fatty acids for the prevention of postoperative atrial fibrillation during coronary artery bypass grafting in patients with coronary artery disease requires a thorough analysis of the characteristics of a patient and an assessment of clinical and echocardiographic parameters, factors influencing surgical performance, inflammation, and oxidative stress. Moreover, the dosage of the drug impacts the risk of atrial fibrillation. Omega-3 polyunsaturated fatty acids in short-term therapy reduce the frequency of new episodes of this arrhythmia after the intervention, however, this effect is offset by the combined use of statins. AbstractThe article presents the available literature data on the effectiveness of the use of omega-3 polyunsaturated fatty acids in the prevention of postoperative atrial fibrillation in patients with coronary artery disease during coronary artery bypass grafting. Possible mechanisms of the drug’s antiarrhythmic action are highlighted, including its anti-inflammatory and antioxidant effects. The reasons for the decrease in the activity of omega-3 polyunsaturated fatty acids in combination with HMG-CoA reductase inhibitors are discussed.
MECHANISMS OF VASOPROTECTION AND CARDIOPROTECTION IN HYPOXYTHERAPY OF ARTERIAL HYPERTENSION AND CORONARY ARTERY DISEASE

Published: April 2024

Highlights The article presents a modern understanding of the main links of the functional circulatory regulation system and its response to exogenous hypoxia, as well as describes the data available on molecular mechanisms of vasoprotection and cardioprotection involved in response to hypoxytherapy in patients with arterial hypertension and coronary artery disease. AbstractHypoxic conditioning has taken an important place in the range of non-drug methods for stimulating the adaptive potential of a healthy person and patients with cardiovascular diseases. There are many approaches to the use of various methods of exogenous hypoxia, however, there is no consensus on the essence of sanogenetic mechanisms that provide a multi-level functional system for maintaining oxygen supply and blood circulation. Adaptive reactions of afferent, central and efferent links of the functional circulatory regulation system in hypoxia in a healthy person are described. The results of studies of physiological systemic reactions realized by respiratory and vegetative plasticity using interval (intermittent) hypoxia are presented. In patients with arterial hypertension and coronary artery disease, the facts of chemoreflective stimulation and modulation of lung ventilation, autonomic nervous system status, especially sympathetic activity of peripheral blood vessels and vagal activation of cardiac activity have been established. The main vaso- and cardioprotective properties of interval hypoxytherapy are based on the leveling of oxidative stress, inflammation, activation of angiogenesis, and a shift in the secretory activity of the endothelium towards vasodilating, antiproliferative, and antithrombotic mediators. We present the evidence for the role of shear stress and the state of glycocalyx, angiopoietin and adrenomedulline in the regulation of vascular tone, as well as cytoprotective properties of cytoplasmic and mitochondrial metabolic factors in the formation of ischemic tolerance of cardiomyocytes. The issues of the relationship between systemic (neuronal and humoral) reactions and structural and functional responses of target cells in providing adaptive/compensatory mechanisms for regulating blood circulation under the influence of exogenous hypoxia require further research and evaluation.

Purpose: is to propose a model for managing a digital brand image brand based on consecutive feedback loops from the image targetaudience. Methods: collection, processing, and analysis of secondary data were carried out on the basis of desk research, synthesis methods, contentanalysis, and systemic, structural and functional data evaluation using an interdisciplinary approach. Results: systemized methodological approaches in Russian and foreign practice by the authors served as the basis for development of a digital brand image management model based on consecutive feedback loops from the image target audience. Within the framework of the proposed model, it is supposed to create systems in a digital environment for providing feedback to the image target audience and monitoring of formed relationships with consumers. The authors' methodological recommendations for implementation of the proposed model are manifested in detailed approaches to organizing the relationship of the image object with the image target audience through different types of feedback loops, methods of monitoring responses and reactions of target consumers, methods of assessing image in a brand's digital environment to close feedback loops. Conclusions and Relevance: loops of feedback from the brand’s image target audience are a causative mechanism of dynamic nature in which the output data of subjective and objective consumer assessment of brand reputation is used as input data for the management and enhancement of the digital image. Setting up a system of feedback from consumers through digital channels on the basis of consecutive loops allows you to correlate planned indicators of the brand image with the actual indicators, as well as identifi cation of the existing problems and introducing timely adjustments to decisions on managing a brand’s digital image.
