Insulin resistance and other risk factors for atherosclerosis, such as hypertension and hypercholesterolemia, promote endothelial dysfunction and lead to development of metabolic syndrome which constitutes an introduction to cardiovascular disease. The insulin resistance and endothelial dysfunction cross talk between each other by numerous metabolic pathways. Hence, targeting one of these pathologies with pleiotropic treatment exerts beneficial effect on another one. Combined and expletive treatment of hypertension, lipid disorders, and insulin resistance with nonpharmacological interventions and conventional pharmacotherapy may inhibit the transformation of metabolic disturbances to fully developed cardiovascular disease. This paper summarises the common therapeutic targets for insulin resistance, endothelial dysfunction, and vascular inflammatory reaction at molecular level and analyses the potential pleiotropic effects of drugs used currently in management of cardiovascular disease, metabolic syndrome, and diabetes.

Relation of Endothelial Dysfunction and Adipokines Levels to Insulin Resistance in Metabolic Syndrome Patients Obese metabolic syndrome (MS) patients were categorised into three groups: 44 with type 2 diabetes mellitus (T2DM)(D); 20 with T2DM and coronary artery disease (CAD) (DC), and 26 with MS alone (M). Eighteen healthy subjects were selected as controls (C). Insulin resistance (IR) was assessed by HOMA-IR. Adiponectin, tumour necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), and interleukin-8 (IL-8) concentrations were measured by xMAP technology. Endothelin-1 (ET-1) was determined by ELISA. We used laser Doppler imaging for evaluating cutaneous endothelium-dependent vasodilatation in the hand. D and DC groups had significantly elevated IR compared with M or C group (P < 0.01). TNF-α, IL-6, IL-8, MCP-1 and ET-1 levels in DC were significantly elevated compared with other groups (P < 0.001). IL-6, IL-8, MCP-1 and ET-1 in D group were higher than those in C group (P < 0.05). TNF-α, IL-6, IL-8, MCP-1 and ET-1 concentrations were correlated with HOMA-IR indexes and adiponectin levels. All patients had lower adiponectin concentrations than controls (P < 0.001), but there were no differences between the patient groups. Only D and DC groups demonstrated a significant and similar decrease in LDI-Ach marker compared to C group (P < 0.001). LDI-Ach values were significantly correlated with HOMA-IR indexes and adiponectin levels (P < 0.001). Our findings show that obese MS patients have significantly increased HOMA-IR, TNF-α, IL-6, MCP-1 and IL-8 levels, decreased adiponectin concentration, and endothelial dysfunction, but the presence of T2DM and CAD in these patients is associated with more pronounced endothelial dysfunction and increased production of inflammatory cytokines and chemokines.

Abstract Endothelium, the inner layer of the vasculature, represents the interface between blood and organ systems and it is active in the process of contraction and relaxation of vascular smooth muscle and in functions like secretion of vasoactive substances. Endothelial dysfunction is an important cause of cardiovascular disease. The function of the endothelium can be assessed by invasive and noninvasive methods. Endothelial cells produce vasoactive substances like endothelium derived relaxing factor, prostacyclin, nitric oxide, and endothelium derived hyperpolarizing factor. Diabetes mellitus is associated with an increased risk of cardiovascular diseases. Hyperglycemia leads to cardiovascular damage through different pathways, including the polyol and hexosamine pathways, generation of advanced glycation end products, and activation of protein kinase C. Together with hyperglycemia induced mitochondrial dysfunction and endoplasmic reticulum stress, all these can promote the accumulation of reactive oxygen species. The oxidative stress induced by hyperglycemia promotes endothelial dysfunction with an important role in micro and macro vascular disease. Insulin-resistance could be independently predictive of cardiovascular disease. Life style modification and pharmacotherapy could possibly ameliorate the effect of insulin resistance

Cardiovascular disease is the leading cause of death in diabetes mellitus. Endothelial dysfunction is the first step in the development of atherosclerotic vascular lesions, which underlies cardiovascular pathology, and adhesion molecules secreted by the endothelium during inflammatory changes are involved in the progression of this lesion. The objective: the serum level of adhesive molecules (ІCAM-1, VCAM-1, Е-selectin) in hypertensive and non-hypertensive type 2 diabetes patients as a marker of endothelial dysfunction and its relationship with other risk factors for cardiovascular disease was studied. Materials and methods. We examined 64 patients with type 2 diabetes, which were divided into two subgroups: the first subgroup – 41 hypertensive type 2 diabetes patients (age – 53,56±7,14 years, BMI – 32,2±87,4; HbA1c – 9,97±2,02%), the second subgroup – 23 nonhypertensive type 2 diabetes patients (age – 50,5±4,92 years, BMI – 25,4±5,22; HbA1c – 9,09±1,95%). The control group included 18 people without diabetes with normal blood pressure (age – 50,72±6,98 years, BMI – 24,71±4,88; HbA1c – 5,26±0,42%). The serum level was determined by immunoenzyme assay. The significance of the difference between the mean values was determined by the t-Student test. Multifactor regression analysis was used to assess the relationships between the studied factors. Results. We revealed an increase of serum levels of ІCAM-1, VCAM-1, Е-selectin in hypertensive (+71,62%, +68,42%, +66,95%, respectively) and non-hypertensive type 2 diabetes patients (+46,17%, +62,79%, +42,85%, respectively) compared with the control group (p<0,01). The serum concentration of ІCAM-1, Е-selectin was higher in hypertensive type 2 diabetes patients compared to non-hypertensive type 2 diabetes patients (+17,27%, +16,86%, respectively, p<0,01). There was a significant effect of Hb1Ac, lipids, insulin resistance on the serum level of ІCAM-1, VCAM-1, Е-selectin (p<0,01). The corresponding regression equations are derived. Conclusion. There is an increase of serum level of ІCAM-1, VCAM-1, Е-selectin in hypertensive and non-hypertensive type 2 diabetes patients, which indicates the development of endothelial dysfunction. Hypertension, hyperglycemia, dyslipidemia and insulin resistance contribute to the development of these changes.

The article presents the analysis of literature data on the pathogenetic role of endothelial dysfunction (ED) in the development of complications of metabolic syndrome (MS). There are two main signs of MS development - abdominal obesity (AO) and primary insulin resistance (IR). IR and concomitant hyperinsulinemia have both direct and indirect atherogenic effects on vascular walls, lead to the development of dyslipidemia, a number of hormonal and metabolic disorders, activation of the sympathoadrenal system, ie, are the basis of almost all components of MS. Despite the high margin of safety of the circulatory system, there comes a time when, due to frequent vasoconstrictor effects thickening of the walls of resistive vessels occurs to limit local perfusion. The thickening of the walls of arteries develops, that is, the modeling of the vascular wall occurs, leading to an increase of the total peripheral vascular resistance with normal tone of smooth muscles. Currently, the concept of ED is formulated as a key link of insulin resistance and atherogenesis in MS. Methods for studying endothelial function have been created and are introduced into clinical practice. New approaches to directed correction of endothelial dysfunction are being developed. Prospective studies have shown that the degree of endothelial dysfunction may be important in predicting cardiovascular events in patients with or without identified vascular disease. Probably, ED may also be related to the pathogenesis of diabetes mellitus type 2 (DM2). Since all components of MS can have an adverse effect on endothelium, ED can be an extremely common phenomenon in patients with metabolic syndrome and can act as a predictor of increased risk of cardiovascular diseases and DM2 in this population.

Cachexia is a devastating pathology induced by several kinds of diseases, including cancer. The hallmark of cancer cachexia is an extended weight loss mainly due to skeletal muscle wasting and fat storage depletion from adipose tissue. The latter exerts key functions for the health of the whole organism, also through the secretion of several adipokines. These hormones induce a plethora of effects in target tissues, ranging from metabolic to differentiating ones. Conversely, the decrease of the circulating level of several adipokines positively correlates with insulin resistance, metabolic syndrome, diabetes, and cardiovascular disease. A lot of findings suggest that cancer cachexia is associated with changed secretion of adipokines by adipose tissue. In agreement, cachectic patients show often altered circulating levels of adipokines. This review reported the findings of adipokines (leptin, adiponectin, resistin, apelin, and visfatin) in cancer cachexia, highlighting that to study in-depth the involvement of these hormones in this pathology could lead to the development of new therapeutic strategies.

The Relationship

Osteoprotegerin (OPG), a glycoprotein traditionally implicated in bone remodelling, has been recently related to cardiovascular disease (CVD). Human studies show a positive relationship between circulating OPG, vascular damage, and CVD, and as such OPG has emerged as a potential biomarker for CVD. This review focuses on the relationship between circulating OPG and different endocrine cardiometabolic alterations such as type 1 and 2 diabetes. The association of OPG with diabetic complications (neuropathy, nephropathy, or retinopathy) as well as with atherosclerosis, coronary artery calcification, morbidity, and mortality is pointed out. Moreover, OPG modulation by different treatments is also established. Besides, other associated diseases such as obesity, hypertension, and metabolic syndrome, which are known cardiovascular risk factors, are also considered.
