The lymphatic system (LS) is one of the main integrative systems of the body, providing protective and transport functions. In recent years, interactions between LS and adipose tissue (AT) have been of particular interest. Lymphatic vessels play an important role in metabolic and regulatory functions of AT, acting as a collector of lipolysis products and adipokines. In its turn, hormones and adipocytokines that produced in adipocytes (including leptin, adiponectin, IL-6, TNF-α, etc.) affect the function of lymphatic endothelial cells and control the growth of lymphatic vessels. Cooperation between LS and AT becomes pathogenetically and clinically important in lymphedema and obesity. It is known that both primary and secondary lymphedema are characterized by increased fat accumulation which is associated with the severity of lymphostasis and inflammation. Similarly, in obesity, the drainage function of LS is impaired, which is accompanied by perilymphatic mononuclear infiltration in the AT. The development of these changes is facilitated by endocrine dysfunction of adipocytes and impaired production of adipocytokines. The increase in the production of inflammatory mediators and the disruption of the traffic of inflammatory cells causes a further deterioration in the outflow of interstitial fluid and exacerbates the inflammation of the AT, thereby forming a vicious circle. The role of lymphangiogenesis in AT remodeling in obesity needs further research. Another promising area of research is the study of the role of intestinal LS in the development of obesity and related disorders. It has been shown that the transport of chylomicrons from the intestine depends on the expression of a number of molecular mediators (VEGF-C, DLL-4, neuropilin-1, VEGFR-1, CD36/FAT, etc.)in the endotheliocytes of the intestinal lymphatic vessels, as well as the functioning of «push-button» and “zippering” junctions between endothelial cells. New approach to the treatment of obesity based on blockade of lymphatic chylomicrontransport has been experimentally substantiated. Further identification of the molecular mechanisms and signaling pathways that determine the remodeling of AT in lymphedema and obesity are likely to provide new approaches to the treatment of these diseases.

The prevalence of metabolic syndrome (MS) has a worldwide tendency to increase and depends on many components, which explains the complexity of diagnostics and approaches to the prevention and treatment of this pathology. Age, lifestyle, socioeconomic status, insulin resistance (IR), dyslipidemia, obesity and genetic predisposition are factors influencing the risk of developing and progression of MS. Features of the distribution and dysfunction of adipose tissue are important factors in the development of IR, with obesity, as well as the risk of the formation of cardiometabolic diseases and MS. Understanding of mechanisms is linked to advances in metabolic phenotyping. Metabolic phenotyping of obese persons is important for the development of important diseases in relation to the study of the pathophysiology of metabolic disorders, the possible concomitant disease and the search for innovative strategies for the prevention and treatment of MS. The understanding of MS mechanisms is associated with advances in metabolic phenotyping. Therefore, the relevance of further study of the pathophysiological mechanisms underlying various metabolic phenotypes of MS is one of the promising areas of modern scientific research. This review summarizes the current literature data on the prevalence of MS depending on gender, age, population, area of residence, education, level of physical activity, and many other parameters. Metabolic risks of MS development are detailed. Biological markers of MS are considered. The necessity of metabolic phenotyping of MS has been shown, which may have potential therapeutic value.

Background: Aldosterone-producing adrenocortical adenoma (APA) is responsible for the majority of cases clinically diagnosed as primary aldosteronism. Aldosterone synthase (CYP11B2) is one of the enzymes that play essential roles in aldosterone synthesis and is involved in the pathogenesis of primary aldosteronism. Recent studies have demonstrated that various factors influence the expression and function of CYP11B2 in APA. In particular, somatic mutations, such as gain-of-function and loss-of-function mutations have been identified in several genes, each of which encodes a pivotal protein that affects the calcium signaling pathway, the expression of CYP11B2, and aldosterone production. On the other hand, CYP11B2 also catalyzes the conversion of cortisol to 18-hydroxycortisol and subsequently converts 18-hydroxycortisol to 18-oxocortisol. The article also discusses the clinical significance of 18-oxocortisol, an important biomarker for the diagnosis of primary aldosteronism. Somatic mutations in aldosterone-driver genes are strongly associated with CYP11B2 expression and have been only detected in the CYP11B2-positive tumor area, that indicating heterogeneous expression of CYP11B2 in tumor.Aim: to assess the functional heterogeneity of adrenal tumors in primary aldosteronismMaterials and methods: Retrospective evaluation adrenal tumors from patients with primary aldosteronism (n=20). According to CT unilateral macrohyperplasia was detected in 19 patients (95% of total), all of them were confirmed to have unilateral hyperproduction of aldosterone according to AVS. Selected tumors werestained with anty-CYP11B2 antibody. We evaluated the CYP11B2 expression in the adenoma and in the adjacent adrenal cortex.Results: Immunohistochemistry studies of the resected adrenals from 20 patients with PA operated due to unilateral production of aldosterone using CYP11B2 staining showed that 10 of those with an adenoma on CT scanning showed CYP11B2 staining in the adenoma. Furthermore, 5 cases of an unilateral adenoma, showed CYP11B2 staining in the adjacent adrenal cortex and an absence of staining for CYP11B2 in the adenoma. 5 cases showed CYP11B2 expression is heterogeneously immunolocalized throughout the tumor area.Conclusion: Thus, the functional heterogeneity of adrenal tumors in primary aldosteronism has been proven. It is necessary to compare the data of immunohistochemical studies on the expression of CYP11B2 with the indicators of the level of 18-hydroxycortisol, 18-oxocortisol.

Background: The use of testosterone replacement therapy (TRT) is widespread. Despite the positive changes, such as: an increase in testosterone levels, an improvement in erectile function and an increase in libido, it is possible to develop a negative manifestation — hyperestrogenism. To date, there are no studies assessing the prevalence of hyperestrogenism in the presence of TRT.Aim: To study the reliability of an increase in total testosterone and estradiol levels and changes in total weight, body mass index (BMI), waist circumference (WC) and hips (OB), depending on the type of TRT and hCG therapy.Materials and methods: For retrospective analysis, the medical records of patients with baseline testosterone deficiency and normal estradiol levels, who were prescribed TRT or hCG therapy, were selected. The patients were divided into 3 groups depending on the form of TRT and hCG therapy. The level of testosterone, estradiol, sex hormone binding globulin (SHBG), weight, OT, OB, BMI in each group was assessed 2 times — before the appointment of treatment and at different periods of treatment, for example, after 3–6–9 and 12 months. Most of the patients had a period of monitoring these parameters before the appointment of TRT or hCG therapy and after 6 months.Results: The increase in the levels of total testosterone and estradiol against the background of TRT in the total sample was 109.6% and 111.3%, respectively. In each group, increases in total testosterone and estradiol levels were significant, p ≤ 0.001. The level of total testosterone to physiological values increased only in the 2-nd group — reaching the average-normal, recommended levels, from 8.7 ± 0.5 (2.5) to 16 ± 2 (10). The maximum rises in total testosterone, as well as estradiol, were noted in the 1st group, from 9.5 ± 0.72 nmol / L (3) to 24.9 ± 2.7 nmol / L (11.62)) and with 24.19 ± 2 (8.5) to 58.1 ± 4 (18.1), respectively. TRT, like hCG therapy, promotes an increase in the level of estradiol, which was demonstrated in all groups, and not only in group 1-st: in group 2-nd from 28.1 ± 2.3 (11.3) to 55 ± 4 (20) and in the 3-rd group from 27.1 ± 2.5 (10.5) to 55.8 ± 4.6 (19.6). On average for the entire sample, from 26.6 ± 1.32 (10.2) to 56.2 ± 2.5 (19). Weight loss on TRT was significant only in the 2-nd group, and in all parameters — weight, BMI, waist and hip circumference. In the 3-rd group, BMI, WC and OB values also slightly decreased. In the 1-st group, the total weight slightly increased, while the BMI did not change, as did the OB value, and the OT value decreased slightly.Conclusion: TRT significantly increases the levels of total testosterone and estradiol, contributing to the normalization of testosterone levels, as in the 2-nd group, or the development of supraphysiological levels of total testosterone and hyperestrogenism, as in the 1st and 3-rd groups.

Background: Considering the influence of visceral obesity on male infertility, the investigation of ejaculate quality indicators under obesity treatment is relevant.Objective: Evaluation of ejaculate quality indicators by obesity treatment with liraglutide in andrologically healthy men with infertility and post-pubertal visceral obesity.Methods: Infertile men with post-pubertal alimentary visceral obesity were included in a pilot observational prospective study. All patients were given recommendations for body weight loss (hypocaloric diet, daily aerobic physical activity) as well as an average daily dose of liraglutide 2.4 [2.4; 3.0] mg. Evaluation of waist circumference, antioxidant activity of ejaculate, spermogram was carried out initially and after 6 months. The differences were considered statistically significant at p <0.005.Results: The body weight decrease was -11.7 [12.4; 11.0]%, the waist circumference decrease was 8 [12; 7] cm. In dynamics, increased content of living sperm in ejaculate from 92 [90; 95]% to 95 [92; 98]%, morphologically normal forms from 5 [3; 6]% to 6 [3; 8]%, mobility of A + B from 25 [15; 36] to 35 [19; 52]%, seminal antioxidant capacity, a decrease in reactive oxygen forms in the neat ejaculate were statistically significant. Increasing the sperm count in 1 ml and decreasing reactive oxygen forms in the washed ejaculate did not reach statistical significance.Conclusion: Ejaculate quality indicators improved by the complex obesity therapy with liraglutide in young andrologically healthy men with postpubertal visceral obesity.

Increasing the sperm count in 1 ml and decreasing reactive oxygen forms in the washed ejaculate did not reach statistical significance.Conclusion: Ejaculate quality indicators improved by the complex obesity therapy with liraglutide in young andrologically healthy men with postpubertal visceral obesity.","PeriodicalId":54700,"journal":{"name":"Obesity and Metabolism-Milan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42238010","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}
Some environmental chemicals capable of interfering with the endocrine regulation of energy metabolism and the structure of adipose tissue in the function of the reproductive, immune, cardiovascular and other systems are called endocrine disruptors or disruptors. According to the WHO definition, the term «endocrine disruptors» means: «Exogenous substances or mixtures thereof that alter the function (s) of the endocrine system and, as a result, cause adverse effects in the intact organism or in its offspring, or (sub) population.» This includes compounds to which humanity is exposed in daily life as a result of their use in pesticides, herbicides, industrial and household products, plastics, detergents, refractory impregnations and as ingredients in personal care products. This review will present the latest scientific data on various ERs, such as persistent organic pollutants (POPs): pesticides (mirex, chlordecane, endosulfan, hexachlorobenzene-HCB dichlorodiphenyltrichloroethane-DDT and its metabolites), industrial chemicals (bisphenol A, polybrominated ether -PBDE, polychlorinated biphenyls-PCB, nonylphenol, dioxins, perfluorooctanoic acid-PFOA, phthalates), pharmaceuticals (diethylstilbestrol-DES). ERs are regarded as compounds that cause obesity, since they have the ability to influence cellular processes associated with adipose tissue, initiating changes in lipid metabolism and adipogenesis. Analysis of scientific materials on this issue indicates that ERs are ubiquitous in the environment and have a detrimental effect on the health of animals and mankind. The scientific and practical interest in this article is based on the growing statistics of the development of such socially significant pathologies as obesity and related diseases, including diabetes mellitus, metabolic syndrome, cardiovascular diseases, menstrual irregularities, as well as cancer and infertility, for of which obesity is a risk factor.

Obesity is an important health problem in many countries. Obesity among the child population is growing steadily, including the Russian Federation. Development of this disease often occurs in childhood and sometimes the origin of obesity goes back to prenatal period. There are a number of endogenous and exogenous factors than play an important role in development of obesity. These are heredity, socioeconomic status of the family, factors which are revealed during pregnancy and child delivery — weight gain, administration of antibacterial drugs and hyperglycemia in mother during her pregnancy, mode of delivery, feeding type and time of complementary food introduction, excessive consumption of calories with food, improper daily routine and lack of sleep, skipping meals, use of gadgets and associated physical inactivity and excessive food intake, marketing of high-calorie foods and others. Prevailing risk factors can be identified for each age period. Study and early identification of risk factors taking into account age of a child is necessary to take timely prevention measures and inform parents and their children about possible reasons and consequences of obesity.
