Samoilyk","doi":"10.14739/2310-1237.2021.2.217936","DOIUrl":"https://doi.org/10.14739/2310-1237.2021.2.217936","url":null,"abstract":"Aim. To stratify hemodynamic phenotypes in children with diabetes mellitus and their frequency, depending on the duration of the disease.\u0000Materials and methods. The study involved 72 children suffering from diabetes, aged 10 to 16 years who were divided into 3 groups. The first group – 22 children with diabetes mellitus up to 1 year. The second group – 24 patients with a disease duration of 1 to 5 years. The third group – 26 children with the disease over 5 years. Control group – 20 children, representative by age and sex.\u0000All children underwent daily blood pressure monitoring (ABPM) with the ABPM-04 device (Meditech Ltd, Hungary). Diagnosis of latent hemodynamic disorders was performed by the method of quantitative analysis of the relationships of blood pressure parameters, which involved a linear regression of systolic blood pressure by pulse blood pressure. According to the results of regression, 6 hemodynamic phenotypes were determined, which characterized the individual features of the circulatory system: harmonic, myocardial-insufficient subtype of harmonic, borderline diastolic harmonic, borderline systolic harmonic, dysfunctional diastolic and dysfunctional systolic. According to ABPM results, the ambulatory arterial stiffness index (AASI) was calculated using a linear regression equation. The results were statistically processed using statistics software package Statistica 13.0 (StatSoft Inc., No. JPZ8041382130ARCN10-J).\u0000Results. It was found that in the dynamics of diabetes the registration of the harmonic hemodynamic phenotype during the day decreased due to an increase in the proportion of patients with dysfunctional diastolic hemodynamic phenotype. At the same time, in children with diabetes, there was a significant increase in AASI from the first year of the disease with a progressive increase with its dynamics. The highest values of AASI were observed in dysfunctional hemodynamic phenotype.\u0000Conclusions. In children with diabetes mellitus observed the formation of disharmonious hemodynamic phenotypes in the dynamics of the disease. In combination with increased vascular stiffness these changes realized in systemic circulatory disorders and the development of a diabetic angiopathy. Detected disorders, apparently, became the risk factors of hypertension. Determination of hemodynamic phenotype in children with diabetes mellitus can be used as screening method for preclinical diagnosis of latent disorders of the cardiovascular system, early treatment and prevention.","PeriodicalId":41645,"journal":{"name":"Pathologia","volume":"37 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77935663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its elevated levels are determined in a wide range of both acute and chronic forms of cardiovascular diseases. The inflammation results in the release of the enzyme from the white blood cells to form products such as hypochlorous acid, which in turn can have a negative effect on the target proteins. Inconsistent evidence on the predictive role of this biomarker in diseases of the circulatory system generates scientific interest and provokes further research in this direction.\u0000The aim of this review is to analyze the scientific literature data on myeloperoxidase as a possible clinical use for the diagnosis and risk stratification of patients with саrdiovascular diseases.\u0000Materials and methods. Searching and generalization of data from leading specialized sources, which are indexed by scientific databases PubMed, SCOPUS, Web of Science.\u0000Results. The results of the studies indicate that myeloperoxidase is actively involved in the pathophysiology of cardiovascular diseases through participation in oxidative stress and inflammation, excessive production of proatherogenic lipoproteins, changes in nitric oxide activity, endothelial dysfunction, and due to the effect on the instability of atherosclerotic plaques. In patients with cardiovascular diseases, including ischemic heart disease, the concentration of the indicated protein is increased and is often associated with a poor prognosis, including an increased risk of mortality. Myeloperoxidase metabolites are often the factors that contribute to cell damage under conditions of ischemia. The review also considers the relationship of the enzyme with the development of restenosis and the effectiveness of revascularization after percutaneous coronary intervention.\u0000Conclusions. The presented data mainly define myeloperoxidase as a significant marker for predicting long-term follow-up results and the development of serious adverse cardiovascular events, mortality in patients with cardiovascular disease. At the same time, despite the great achievements in disclosing the complex effects of myeloperoxidase, inconsistency in the available results is noteworthy.

Deviation of them can detect myocardial ischemia, hypertrophy, dystrophy and infiltration, severe systemic diseases, cardiotoxicity of the drugs, etc.\u0000This technology significantly improves diagnostic capabilities of transthoracic echocardiography, it allows to assess myocardial function in all three planes (longitudinal, circumferential and radial), in which myocardium moves during cardiac cycle. Speckle tracking echocardiography can determine the volume of myocardial damage, differentiate subendocardial and transmural myocardial infarction, identify viable and fibrous areas of the myocardium, that is confirmed by the results of magnetic resonance imaging. Besides, this method helps to detect and assess mechanical dyssynchrony and also predict the risk of pathological left ventricular remodeling and life-threatening adverse cardiovascular events (arrhythmias, increasing of heart failure, recurrent myocardial infarction, stroke, death, etc.), that is important for patients with acute myocardial infarction to identify high-risk patients. \u0000The most studied markers of this technique are longitudinal, circumferential and radial strain, mechanical dispersion and postsystolic shortening.

All patients were divided into 4 groups depending on the severity of the disease and the presence of complications.\u0000All patients included in the study on the day of admission to the hospital and on the 10th day of hospital stay were examined for serum concentrations of pro- and anti-inflammatory cytokines as well as interferons alpha and gamma, which was carried out by solid-phase enzyme immunoassay using kits manufactured by “Vector-best” company (RF) according to the manufacturer’s instructions.

The study of the levels of pro- and anti-inflammatory cytokines in dynamics showed a decrease in their levels on the 10th day of hospital stay in patients who did not have complications, and their increase in patients whose illness was accompanied by the development of pneumonia. Levels of INFα and INFγ in dynamics increased in all groups of patients. Significant changes in relation to the control group in the ratio of pro- and anti-inflammatory cytokines in the dynamics were observed only in patients with a dissociative type of cytokine response. In patients of this group on the 1st and 10th days of hospital stay the ratio index of IL-6/IL-10 was shifted towards a significant predominance of proinflammatory cytokines.\u0000Conclusions. The study demonstrates the presence of three possible types of cytokine response in patients with measles infection of varying severity: normoreactive, dissociative and hyporeactive. Each type was typical to a specific group of patients and influenced the clinical course of the disease and the development of complications, which is associated with the dynamics of increasing levels of pro- and anti-inflammatory cytokines and increasing levels of INFα and INFγ. The dynamics of increase in levels of these factors in severe disease is lower than in moderate disease.

To determine the probable role of ferroptosis in the course of inflammatory bacterial diseases of the respiratory system in young children, accompanied by the development of anemia of inflammation.\u0000Materials and methods. The study included 62 children (mean age 1.4 ± 0.4 years). The main group included 42 children with acute inflammatory bacterial diseases of the respiratory system, accompanied by anemia of inflammation: 29 children were diagnosed with bacterial bronchitis, 13 children – pneumonia. Determination of the severity of inflammatory diseases was determined by Acute Bronchitis Severity Score and Pediatric Respiratory Severity Score. At the time of participation in the study, all patients under observation had no signs of impaired iron metabolism, including iron deficiency anemia, in the anamnesis. The control group included 20 relatively healthy children. The content of caspase-7, caspase-9, ferritin, nitrotyrosine, phospholipase A2 was determined by ELISA using commercial kits.\u0000Results. We hypothesized the ineffectiveness of apoptosis in the course of bacterial inflammatory processes of the respiratory organs in young children, accompanied by the development of anemia of inflammation, and studied the probability of ferroptosis in these conditions. The obtained data indicated the presence of active oxidative stress in the main group patients. The strong direct correlation between the severity of inflammatory disease and the intensity of oxidative stress was revealed (r = 0.7, P < 0.001). A statistically significant increase in ferritin content in the main group compared with the control group was observed. There was a strong direct correlation between ferritin levels and the severity of bronchitis (r = 0.82, P < 0.01) and the severity of pneumonia (r = 0.87, P < 0.01).
