Endogenous hypercortisolism is a severe endocrine disease characterized by prolonged exposure to excessive amounts of glucocorticoid hormones, accompanied by a wide range of symptoms and complications, including immunosuppression. Timely surgical treatment in most cases allows to save the patient’s life, significantly improve its quality. However, restoration of the normal concentration of glucocorticoid hormones can become a trigger factor in the development or exacerbation of autoimmune and auto-inflammatory diseases. We present a clinical case of atypical gout in a patient with hypercortisolism and a progressive increase in symptoms of the disease after successful surgical treatment for Cushing’s disease and achieving stable remission. The issues of diagnosis and treatment of this group of autoinflammatory diseases are highlighted, the leading clinical and radiological symptoms are considered, the differential diagnosis of microcrystalline (metabolic) arthritis is presented. Despite the widespread, the diagnosis and treatment of this group of diseases still cause difficulties for specialists. A competent choice of drug therapy allows to fully control diseases considered in the article, including when they are combined, and thereby improve the quality of life of the patient.

BACKGROUND: Increased consumption of sweet and high-calorie foods leads to weight gain in humans and the development of metabolic syndrome. Great attention is given to a personalized approach to nutrition correction based on genetic testing. The genetic basis for human taste sensitivity to sweet stimuli remains is understudied. The role of the g.18853330 A>G (rs4920566) polymorphism of the TAS1R2 gene in preference for sweets has not been fully studied.AIM: To investigate the possible relationship between rs4920566 polymorphism in TAS1R2 gene and sensitivity to natural sugars and food preference of high-calorie sweet foods in humans.MATERIALS AND METHODS: A single-sample experimental study was carried out. The study participants were conditionally healthy students who voluntarily agreed to conduct it. Sugar sensitivity was assessed in two tasting tests. Sucrose sensitivity thresholds (STS) were determined by staircase procedure (solutions: 8.0 to 500 mM/l). To assess food preferences for sweet foods, specially designed questionnaires with a checklist of products were used. Genomic DNA samples from all study participants were obtained from buccal epithelial cells. Genomic DNA was extracted from buccal epithelial cells using the adsorption of DNA with an inorganic sorbent in the presence of a chaotropic agent. Typing of the rs4920566 polymorphism in TAS1R2 gene was performed using asymmetric real-time PCR.RESULTS: The study included 26 young men and 110 young women which the average age was 20.8±4.8 (SD) years. Gender was a significant factor affecting the taste perception of the sweetness sugars (maltose, glucose, sucrose and fructose) in students. Young men more often than young women could not distinguish the taste of four sugars (β=-2.93(0.99), p=0.003). The rs4920566 polymorphism in TAS1R2 gene did not affect the ability of students to distinguish the taste of four natural sugars. It was found that the variation series of STS values for sucrose in young women with the A allele (16.0[16.0–31.0] versus 16.0[8.0–16.0] mmol/l, pcor=0.002) and A/G genotype (16.0[16.0–31.0] vs. 16.0[8.0–16.0] mmol/l, pcor=0.010) were significantly lower compared to young men. Separately, in young women with the G/G genotype the range of STS is shifted towards higher concentrations of sucrose compared with women with the A/G genotype (16.0[16.0–31.0] vs. 16.0[8.0 -16.0] mmol/l, pcor=0.039). Testing the hypothesis about the randomness of the relationship between the rs4920566 genotypes of the TAS1R2 gene and the liking rating of foods with a sweet taste using Kruskal-Wallis test did not allow us to conclude that the A/A, A/G and G/G genotypes of the TAS1R2 gene influence the choice of sugary high-calorie foods in students.CONCLUSION: Our results are consistent with the literature data and confirm that rs4920566 polymorphism of TAS1R2 gene cannot be an informative marker for the diagnosis of metabolic conditions associated with the consumpti

Obesity and type 2 diabetes mellitus (T2DM) are major problems for public health all over the world. According to retrospective research, the prevalence of obesity has doubled in more than 70 countries since 1980, as well as the prevalence of obesity complications (atherosclerotic cardiovascular diseases, nonalcoholic fatty liver disease and their complications. There are many drug therapies for T2DM, but it is difficult to achieve a stable, clinically relevant effect on a long-term basis. The fact that a patient has both conditions makes it difficult to optimize carbohydrate metabolism and to achieve normal body weight. Many antidiabetic drugs cause weight again, which, in turn, contributes to the growth of insulin resistance (IR) and requires further intensification of therapy.In the last few years, there is a growing evidence of the relationship between the gut microbiota (GM), obesity and T2DM. There has been a steady growth of interest in such medical technology as fecal microbiota transplantation (FMT) in the world. Since there is data on the association of the gut microbiota (GM) with the development of IR and T2DM, the possibility of FMT can potentially be one of the new methods of treatment. This review presents the current state of the problem and discusses the possibility of modifying GM as a therapeutic strategy in obesity and T2DM with an accent on autologous fecal microbiota transplantation.

The article presents data of the influence of cytokines of different directions of glucose and lipid metabolism in obesity. A change of the basic paradigm regarding adipose tissue has contributed to a number of recent discoveries. This concerns such basic concepts as healthy and diseased adipocytes, and, as a consequence, changes of their metabolism under the influence of cytokins. Distinguishing the concept of organokines demonstrates that despite the common features of cytokine regulation, each organ has its own specifics features of cytokine regulation, each organ has its own specific an important section of this concept is the idea of the heterogeneity of adipose tissue. Knowledge of the function of adipose tissue localized in different compartments of the body is expanding. There are date about the possibility of transition of one type of adipose tissue to another. A possible mechanism linking adipose tissue inflammation and the formation of insulin resistance (IR) is presented in this paper. The mechanism of IR development is closely connected with to proinflammatory cytokins disordering the insulin signal, accompanied by a decrease of the work of glucose transporters. A decrease of the income of glucose into cells leads to a change of glycolysis level to an increase of the fatty acids oxidation. Cytokins are able to participate in the process of the collaboration of some cells with others, that occurs both during physiological and pathological process.

Water balance in the body is achieved by balancing renal and non-renal water losses with corresponding water intake. It is under the control of both the central nervous system, which integrates many parameters of water and electrolyte balance in the body, including inducing important adaptive behavioral responses, and three hormonal systems: vasopressinergic, renin-angiotensin-aldosterone and apelinergic. A lot of research is devoted to the regulation of water-electrolyte metabolism. However, this process is still quite difficult to understand, especially since more and more of its regulators are being discovered over time. One of them is the hormone apelin, an endogenous ligand for the APJ receptor. As is known, the receptor is highly expressed in many organs, such as the brain, heart, liver and kidneys, lungs, and has multidirectional effects.This literature review discusses the main characteristics and features of the regulation of these systems in relation to water-electrolyte metabolism, as well as issues of intersystem interaction and modulation of the effects of apelin.

BACKGROUND: Obesity and androgen deficiency (AnD) are characterized by similar disturbances in metabolic parameters, the presence of signs of insulin resistance, metabolic syndrome, the risk of developing cardiovascular diseases (CVD) and vascular complications. These facts indicate the possibility of the presence of common mechanisms that determine the predisposition to the development of obesity and AnD, which may include genetic factors, in particular, the rs4646994 polymorphism of the ACE gene, which, according to recent data, is associated with the risk of developing CVD, hypertension, and obesity.AIM: To study the association of the carriage of polymorphic variants of the rs4646994 locus of the ACE gene with the features of anthropometric and androgenic status in men.MATERIALS AND METHODS: In the period from April 2020 to October 2021 there were observed male patients aged 18–75 years old, who were hospitalized in a therapeutic hospital because of comorbid somatic pathology (hypertension, coronary heart disease, dorsopathy, vegetative-vascular dystonia, gastroesophageal reflux disease, and others). Anthropometry, a study of the content of hormones of the reproductive system in the blood serum using enzyme-linked immunosorbent assay (ELISA), as well as a genetic study for the carriage of polymorphic variants of the rs4646994 locus of the ACE gene by the polymerase chain reaction (PCR) method, followed by electrophoresis of PCR products, were carried out. RESULTS: 82 patients took part in research. According to the results of genetic analysis, 17 people were assigned to the group of homozygotes for the wild type (I/I, G1), 41 people were assigned to the group of heterozygotes (I/D, G2), and 41 people were assigned to the group of homozygotes for the mutant allele (D/D, G3) 24 people. Body weight, chest circumference, waist and hips, body mass index in patients carrying the D allele of the rs4646994 polymorphism were statistically significantly higher than in I/I homozygotes. Differences in hormonal status also turned out to be statistically significant: patients from G1 compared with G2 and G3 had higher levels of total testosterone; from G1 compared to G3 — a higher level of free testosterone.CONCLUSION: An association of the carriage of the D allele of the rs4646994 polymorphic locus of the ACE gene with overweight and ADI was revealed.

Gout is a disease characterized by deposition of sodium monourate crystals in tissues which is the reason of inflammation among persons with hyperuricemia (HU). The prevalence of HU, which can be considered the first stage of gout formation, varies in different countries. Despite this, only a small number of persons with HU have been shown to develop symptoms of gout. Recent data suggest that HU is an independent risk factor for cartilage and bone damage. UA, both in the form of crystals and in a dissolved form, activates damage and potentiates cell death by releasing reactive oxygen species, activating the necroptosis pathway, neutrophil traps, synthesis of pro-inflammatory cytokines, and other pathogenetic mechanisms that cause the negative effects of HU and gout on articular cartilage and subchondral bone. The association of HU and osteoarthritis (OA) is well known and based on the common pathogenesis, but the direction of this relationship is still a debatable issue. The accumulated data suggest the need for a deeper study of the relationship of gout and asymptomatic HU with pathological processes leading to the development and progression of OA and disorders of bone metabolism.

There is a great worldwide trend in the incidence of obesity, which is increasing with each passing year among all populations, including women of reproductive age. Given the impressive list of diseases associated with obesity, as well as the negative inverse correlation of the severity of obesity with fertility, this problem is global not only in the social sphere, but it also becomes demographically significant.Along with other pathogenetic mechanisms leading to persistent anovulation, an imbalance in adipokine production by adipose tissue can also serve as one of the important links in the development of reproductive dysfunction. Despite apparent interest in this topic, a large number of previously discovered adipokines are still not studied. Among adipokines, the effects of adiponectin and leptin on reproductive function are best known. Alterations in adiponectin and leptin levels can affect hypothalamic-pituitary-gonadal signaling, folliculogenesis, oogenesis and steroidogenesis. In addition, leptin is involved in the initiation of puberty, regulation of the menstrual cycle, and changes the balance between proliferation and apoptosis in ovarian cells. The leading causes of reduced fertility, infertility, and IVF failure in obese patients are mechanisms that promote the formation of chronic anovulation, delay the maturation of oocytes, reduce their quality, and/or lead to changes in endometrial susceptibility. These effects can be caused by an imbalance in the concentrations of leptin and adiponectin (leptin excess and adiponectin deficiency), lead to endometrial dysfunction, disruption of implantation and early embryogenesis. These changes, in turn, can affect just as the likelihood of spontaneous conception, so the effectiveness of assisted reproductive technologies and subsequent gestation.Thus, the study of potential pathogenetic pathways of fertility regulation in obesity, one of which is the subject of this review, is an important area for further study.

These changes, in turn, can affect just as the likelihood of spontaneous conception, so the effectiveness of assisted reproductive technologies and subsequent gestation.Thus, the study of potential pathogenetic pathways of fertility regulation in obesity, one of which is the subject of this review, is an important area for further study.","PeriodicalId":54700,"journal":{"name":"Obesity and Metabolism-Milan","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41698650","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}

The medical and social significance of cardiovascular diseases remains high. One of the factors that determine cardiovascular risks is metabolic syndrome. As a result of excessive accumulation of lipid and carbohydrate metabolism products in metabolic syndrome, oxidative (oxidative) stress develops. The article considers both domestic and foreign scientific studies, which highlight various aspects of the influence of reactive oxygen and nitrogen species, as well as other free radicals on the formation of oxidative stress in pathological conditions that are part of the metabolic syndrome complex. This describes the mechanisms of the formation of chronic inflammation through excessive secretion of pro-inflammatory cytokines and adipokines, activation of the transcription factor NF-kB, as well as damage to the antioxidant system in obesity. Separately, a number of mechanisms of the stimulating effect of adipokines: leptin, adiponectin, chimerine, omentin 1, resistin, on the formation of oxidative stress have been noted. The ways of activating the polyol pathway, as well as diacyl-glycerol — protein kinase C — the signaling pathway of oxidative stress, the formation of mitochondrial dysfunction is described. As a result of which there is an excessive production of free radicals in insulin resistance, diabetes mellitus and macroand microvascular complications of diabetes. In addition, the influence of oxidative stress directly on the formation of cardiovascular diseases of atherosclerotic genesis, as well as arterial hypertension, has been shown.

BACKGROUND: The decisive importance of the sympathetic and parasympathetic nervous system in maintaining vegetative homeostasis requires the determination of sensitive non-invasive parameters of multidimensional outpatient monitoring of cardiorespiratory adaptation under various physiological and clinical conditions, taking into account the function of external respiration (FER), compound body composition and heart rate variability (HRV).AIM: To identify concomitant changes in HRV, HR and compound body composition in young people as markers of cardiorespiratory adaptation and rehabilitation.MATERIALS AND METHODS: On the basis of the Kuban State Medical University, a single-centre, interventional, cross-sectional, single-sample, comparative, uncontrolled study of a general group of young people in which respiratory parameters and parameters of the compound body composition were determined. Some individuals in this group additionally underwent Holter monitoring of the electrocardiogram (ECG) at short intervals.RESULTS: In young people, a change in the compound body composition with an increase in total fat mass, visceral and body fat is associated with a decrease in respiratory function (a decrease in the Tiffno index, a decrease in the maximum middle-expiratory flow — MMEF), manifested by a decrease in HRV (according to the TI indicator), the absence of an increase in the autonomic regulation circuit (according to SDNN indicator), a decrease in parasympathetic activity (in terms of rMSSD) and the absence of sympathetic activation (in terms of SDANN). Positive shifts in the form of an increase in trunk muscles, the total amount of water and a decrease in the total fat mass are accompanied by an increase in lung capacity, forced expiratory volume in the first second and a change in HRV with sympathetic (in terms of LF / HF, SDANN) and parasympathetic activation (in terms of rMSSD), an increase in HRV (in terms of TI) and an increase in the autonomic regulation circuit of the vegetative nervous system (in terms of SDNN).CONCLUSION: Accurate and rapid diagnostics of vegetative homeostasis requires a comprehensive correlative analysis of the parameters characterizing HRV in short recordings, the compound composition of the human body and respiratory function.
