Role of insulin, adenosine, and adipokine receptors in the foetoplacental vascular dysfunction in gestational diabetes mellitus. Biochim Biophys Acta Mol Basis Dis 2019; 1866:165370. [PMID: 30660686 DOI: 10.1016/j.bbadis.2018.12.021] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2018] [Revised: 12/18/2018] [Accepted: 12/21/2018] [Indexed: 12/11/2022]
Abstract
Gestational diabetes mellitus (GDM) is a disease of pregnancy associated with maternal and foetal hyperglycaemia and altered foetoplacental vascular function. Human foetoplacental microvascular and macrovascular endothelium from GDM pregnancy show increased maximal l-arginine transport capacity via the human cationic amino acid transporter 1 (hCAT-1) isoform and nitric oxide (NO) synthesis by the endothelial NO synthase (eNOS). These alterations are paralleled by lower maximal transport activity of the endogenous nucleoside adenosine via the human equilibrative nucleoside transporter 1 (hENT1) and activation of adenosine receptors. A causal relationship has been described for adenosine-activation of A2A adenosine receptors, hCAT-1, and eNOS activity (i.e. the Adenosine/l-Arginine/Nitric Oxide, ALANO, signalling pathway). Insulin restores these alterations in GDM via activation of insulin receptor A (IR-A) form in the macrovascular but IR-A and IR-B forms in the microcirculation of the human placenta. Adipokines are secreted from adipocytes influencing the foetoplacental metabolic and vascular function. Various adipokines are dysregulated in GDM, with adiponectin and leptin playing major roles. Abnormal plasma concentration of these adipokines and the activation or their receptors are involved in the pathophysiology of GDM. However, involvement of adipokines, adenosine, and insulin receptors and membrane transporters in the aetiology of this disease of pregnancy is unknown. This review focuses on the pathophysiology of insulin and adenosine receptors and l-arginine and adenosine membranes transporters giving an overview of the key adipokines leptin and adiponectin in the foetoplacental vasculature in GDM. This article is part of a Special Issue entitled: Membrane Transporters and Receptors in Pregnancy Metabolic Complications edited by Luis Sobrevia.

Abstract
Adipose tissue, which was once considered as a simple energy storage depot, is now recognized as an active endocrine organ that regulates the whole-body energy homeostasis by secreting hundreds of bioactive substances termed adipokines. Dysregulation of adipokines is a key feature of insulin resistance and a metabolic syndrome associated with obesity. Adipokine dysregulation and insulin resistance are also associated with energy-deprivation conditions, such as frailty in old age. Previous studies have demonstrated that preserved insulin sensitivity and low prevalence of diabetes are the metabolic peculiarities of centenarians, suggesting the possible role of adipokine homeostasis in healthy longevity. Among the numerous adipokines, adiponectin is regarded as unique and salutary, showing negative correlations with several age- and obesity-related metabolic disturbances and a positive correlation with longevity and insulin sensitivity among centenarians. However, large-scale epidemiological studies have implied the opposite aspect of this adipokine as a prognostic factor for all-cause and cardiovascular mortality in patients with heart failure or kidney disease. In this review, the clinical significance of adiponectin was comparatively addressed in centenarians and the very old, in terms of frailty, cardiovascular risk, and mortality.

Abstract
Obesity has reached pandemic proportion and represents a major risk for several comorbidities. In addition to metabolic and cardiovascular obesity-related diseases, recent evidence suggested that obesity might affect immune system function. Adipose tissue is considered an endocrine organ that actively secretes cytokines also referred to as "adipokines." Adipokines play an important role in the control of human metabolism. The dysfunctional adipose tissue in obese individuals is characterized by an altered cytokine secretion pattern that promotes chronic low-grade inflammation. Epidemiological evidence highlights the association between obesity and allergic and immune-mediated diseases, such as asthma, allergic rhinitis, rheumatic arthritis, and psoriasis. Less is known about underlying pathogenic mechanisms. However, several recent in vivo and in vitro studies have reported that adipokines are involved in inflammatory and autoimmune disorders by influencing both innate and acquired immune responses. In addition, obesity has been associated with reduced immune surveillance and increased risk of cancer. This paper reviews the evidence regarding the role of adipokines in immune system regulation, with particular emphasis on autoimmune, allergic, and inflammatory disorders. Understanding how obesity affects immune system functions may enable researchers to find new potential therapeutic targets in the management of allergic and autoimmune diseases.

Abstract
Background: Chronic inflammatory diseases take an important place in dermatology and their effects range from mild itching to grave metabolic complications. In psoriasis, association with metabolic syndrome (MS) has been proved in many studies. Chronic inflammation is a trigger of MS, and in turn, the components of MS, namely obesity and dyslipidemia, promote a pro-inflammatory milieu. Thus, chronic inflammation causes MS and vice versa. Hence, the study focuses on association of MS with lichen planus (LP), another chronic inflammatory disease. Aim: The aim of this study is to find the association of MS with all variants of LP. Materials and Methods: An observational study for MS in all patients with LP who attended skin outpatient department (OPD) for 6 months from February 2016. International Diabetes Federation criteria 2005 were used. The confounding variables of MS such as smoking, alcohol, and physical activity were assessed for its significance in the association of LP with MS. Results: Out of 113 cases, 21 cases were found to be associated with MS. Among them, 8 cases (38.09%) were of eruptive LP, which showed significant association with MS when compared to other variants. MS cases were significantly high in females and in the age group of 41–50 (57.1%). Due to unequal distribution of smoking and alcohol habits, they were not taken into account for analysis. Physical activity had no significant association with MS in our study population. Waist circumference (WC) being the mandatory criterion in all variants associated with MS, dyslipidemia was the next frequently encountered criteria except in eruptive LP. High BP was less commonly noted criteria. Conclusion: Eruptive LP showed significant association with MS. Further studies with large sample size in each variant and control group are needed to confirm it which are the limitations in our study.

Abstract
Excessive body weight and obesity in childhood and adolescence are becoming more and more important unfavorable factors that entail extremely adverse consequences and require close attention of physicians of any specialty. Along with the high prevalence of obesity and metabolic syndrome in pediatric patients, children and adolescents in the majority of countries are diagnosed with vitamin D deficiency. Among the non-calcaemic effects of vitamin D, a significant role is played by its impact on the hormonal regulation of glucose metabolism and the synthesis of adipokines by fat tissue. The review presents literature data indicative of a close pathogenic relationship between vitamin D insufficiency and impaired tissue insulin sensitivity. It demonstrates the role of vitamin D insufficiency in immune reactions resulting in development of subclinical inflammation in fat tissue infiltrated with macrophages and lymphocytes. It also shows the role of adipokines, immune system cells and pro-inflammatory cytokines produced by them in the pathogenesis of obesity, as well as the function of vitamin D as an endocrine and paracrine regulator of the process of inflammation in adipose tissue. The relationships between the principal adipokines (leptin, adiponectin, resistin) are revealed in the presence of normal vitamin D content and in vitamin D deficiency. The carbohydrate and lipid metabolism parameters in overweight children and adolescents with vitamin D insufficiency are analyzed. A high prevalence of vitamin D insufficiency in overweight and obese children and adolescents (increasing along with the severity of obesity) is demonstrated. The review also presents the current recommendations for the correction of vitamin D insufficiency and underlines the need for higher cholecalciferol doses to achieve serum calcifediol targets in overweight and obese children and adolescents.

Abstract
AIMS C1q/tumor necrosis factor-related protein-6 (CTRP6) is a novel adipokine and has emerged as an important mediator for lipid and glucose metabolism. However, to date, the relationship between CTRP6 and T2DM in humans has not been demonstrated. Our objective is to investigate the association of circulating CTRP6 with T2DM in a cross-sectional study. METHODS 118 patients with newly diagnosed T2DM, 98 subjects with impaired glucose tolerant (IGT) and 132 healthy subjects were recruited for this study. OGTT were performed in 48 healthy individuals to investigate the association of CTRP6 with glucose, insulin and other adipokines. Circulating CTRP6, TNF-α and Adipoq were measured by ELISA. RESULTS IGT and T2DM individuals had higher serum CTRP6 levels than healthy controls (406.2 ± 136.6 and 539.1 ± 169.7 vs. 354.3 ± 117.2 ng/mL; both P < 0.01), whereas serum CTRP6 concentrations were further increased in T2DM patients compared with IGT individuals (P < 0.01). Serum CTRP6 levels were found to be related positively to BMI, WHR, FAT%, TC, TG, HbA1c, FBG, 2 h-OGTT, fasting insulin (FIns), 2 h-Ins, HOMA-IR and TNF-α, and negatively with HDL-C and Adipoq in all individuals (P < 0.05 or P < 0.01). Multivariate logistic regression analysis demonstrated that CTRP6 was correlated with both IGT and T2DM. After an oral glucose challenge, serum CTRP6 concentrations exhibited a similar change with blood glucose, insulin, TNF-α and Adipoq. CONCLUSIONS CTRP6 may be a metabolism- and nutrition-related adipokine and may be related to insulin resistance and T2DM. TRIAL REGISTRATIONS Clinical Trial Registration Number: ChiCTR-OCC-11001422.

Abstract
Background To evaluate the additional discriminatory performance of adiponectin, leptin, and their ratio in the identification of impaired glucose tolerance (IGT) in men and women without diabetes on top of conventional risk factors. Methods & results A total of 698 subjects underwent an oral glucose tolerance test (oGTT) and adipocytokine measurements. A comprehensive stepwise selection procedure was performed, followed by c-statistics and integrated discrimination improvement (IDI) analysis. In males, adiponectin levels were significantly lower in the IGT group compared to the non-IGT group (Whitney U test, p < 10–4), whereas leptin levels were significantly higher (p = 0.009) in IGT group. In females, adiponectin and leptin levels were not significantly different between groups (Mann-Whitney U test, p = 0.073 and p = 0.08, respectively). Adjusting for the most informative, sex-specific, clinical and biochemical factors, adiponectin, leptin and their ratio were not found to be significant predictors of the response to the glucose load, when modelled as continuous terms or tertiles. In males, the area-under-the-curve (AUC) for adiponectin was estimated at 0.620 (95% CI: 0.558–0.682) and the addition of adiponectin into the basic model provided a ΔAUC benefit of 0.004, showing no additional discriminatory benefit on top of conventional risk factors (IDI p-value: 0.27), nor did the addition of leptin or their ratio. The results were similar in females. Conclusions In Chinese individuals without diabetes, no significant evidence for the potential discriminatory value of adiponectin, leptin or their ratio in the identification of IGT on top of conventional risk factors was observed.

Abstract
It is well established that gestational diabetes mellitus (GDM) identifies a population of women who are at risk of ultimately developing type 2 diabetes (T2DM) later in life. Moreover, this relationship extends across the full spectrum of hyperglycemia in pregnancy, with lesser degrees of gestational dysglycemia identifying a proportionate gradient of future risk of T2DM. Importantly, a growing body of evidence suggests that an analogous relationship exists between hyperglycemia in pregnancy and a woman's long-term risk of cardiovascular disease (CVD), as well. Indeed, as compared to their peers, woman who had GDM have a higher risk of major cardiovascular events, which first manifests within the first decade after the index pregnancy. Although the absolute incidence of such events remains low in young women of child-bearing age, the identification of future risk of CVD at this early point in its natural history may provide the unique opportunity for timely intervention and ideally disease prevention. Thus, in this review, we discuss the emerging concept of hyperglycemia in pregnancy as an indicator of the future risk of CVD in young women and its implications for research and clinical practice.

Abstract
AIMS Gestational diabetes mellitus (GDM) is a medical complication of any degree of glucose intolerance with onset or first recognition during pregnancy. Although visfatin is commonly considered to be related to GDM, studies revealed inconsistent results. This study aimed to clarify the relationship between visfatin and GDM. METHODS The protocol for this study was registered in PROSPERO (No. CRD42018086204) in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). PubMed and Embase databases were used to search for relevant studies published up to September 30, 2017. The difference of visfatin levels between women with GDM and the controls was measured by standardised mean difference (SMD) and 95% confidence interval (CI). RESULTS Twenty-six studies that were published in 24 articles met the inclusion criteria, in which 2305 participants (1033 with GDM, mean age 31.39 years and 1272 controls, and mean age 29.99 years) were included. The quantitative meta-analysis revealed no significant difference in circulating visfatin levels between women with GDM and the controls (SMD = 0.249, 95% CI = - 0.079 to 0.576, P = 0.137). Subgroup analyses were performed referring to body mass index (BMI) where inconsistent results have been observed between cases and controls groups. For the ten studies, in which the level of BMI in women with GDM was higher than that in the control group, the pooled result showed that circulating visfatin was significantly higher among women with GDM than the controls (SMD = 0.367, 95% CI = 0.06 to 0.728, P = 0.046). Of other 16 studies BMI-matched, the pooled SMD illustrated no difference of visfatin. CONCLUSIONS Our study elucidates that visfatin is not independently associated with GDM. Visfatin is linked to GDM through maternal overweight/obesity, which is one of the major factors leading to the development of GDM.

Abstract
Psoriasis is a chronic immune-mediated inflammatory skin disease with possible damage to the musculoskeletal system, affecting 2-3 % of the adult population of the planet. To date, special attention in the treatment of psoriasis is paid to the comorbid background, since it is known that it can aggravate the course of psoriasis and affect the effectiveness of therapy. The purpose of psoriasis therapy is to achieve clean or almost clean skin, sustainable improvement of psoriatic arthritis, improving the quality of life, all this became possible with the advent of genetically engineered biological drugs. However, in the treatment of genetically engineered biological drugs there are “pain points”: primary inefficiency, “the effect of slipping”, the scheme of transition from one drug to another, the safety of the combined use of GIBP and system-based drugs, interruption of therapy.Objective. To study the therapeutic efficacy of ustekinumab in psoriasis patients with forced interruption of treatment, taking into account metabolic disorders.Materials and methods. 52 patients with a diagnosis of plaque psoriasis receiving ustekinumab for 3 years were under observation, which were divided into 2 groups, depending on body weight and metabolic disorders.Results. More than 80 % of patients taking the drug at a dosage of 45 mg, and at a dosage of 90 mg, to week 12 therapy reached PASI 75. By week 24, the proportion of patients in group I who reached PASI 75 was 96.3 %, in group II — 88.0 %.By week 48 PASI 75 reached 90.4 % patients: in group I — 100 % patients, in group II — 80.0 % patients.At 76 weeks, patients were interrupted ustekinumab treatment in connection with the purchase of the drug. The duration of treatment interruption ranged 36 weeks. By week 112, 86.5 % patients in both groups had a relapse of psoriasis, which was assessed by the loss of the therapeutic response of PASI 75.By week 124 (12 weeks after the resumption of therapy) 82.7 % patients reached PASI 75: in group I — 92.6 % patients, in group II — 72.0 % patients.After 16 weeks (week 128), all patients 100 % achieved PASI 75 IN group I. In group II to week 128 PASI 75 was observed in 80 % patients.Conclusion. With the resumption of treatment of patients with psoriasis with ustekinumab after a long interruption, there is a rapid and complete restoration of therapeutic effectiveness, however, in patients with psoriasis with metabolic disorders, there is a decrease in efficiency after the resumption of therapy in comparison with patients without abdominal obesity, which can determine the further strategy and tactics of management of such patients.

Abstract
Inflammatory factors produced and secreted by adipose tissue, in particular peri-pancreatic adipose tissue (P-WAT), may influence pancreatic β-cell dysfunction. Using the ZDF Rat model of diabetes, we show the presence of infiltrating macrophage (ED1 staining) on pancreatic tissue and P-WAT in the pre-diabetes stage of the disease. Then, when the T2D is installed, infiltrating cells decreased. Meanwhile, the P-WAT conditioned-medium composition, in terms of inflammatory factors, varies during the onset of the T2D. Using chemiarray technology, we observed an over expression of CXCL-1, -2, -3, CCL-3/MIP-1α and CXCL-5/LIX and TIMP-1 in the 9 weeks old obese ZDF pre-diabetic rat model. Surprisingly, the expression profile of these factors decreased when animals become diabetic (12 weeks obese ZDF rats). The expression of these inflammatory proteins is highly associated with inflammatory infiltrate. P-WAT conditioned-medium from pre-diabetes rats stimulates insulin secretion, cellular proliferation and apoptosis of INS-1 cells. However, inhibition of conditioned-medium chemokines acting via CXCR2 receptor do not change cellular proliferation apoptosis and insulin secretion of INS-1 cells induced by P-WAT conditioned-medium. Taken together, these results show that among the secreted chemokines, increased expression of CXCL-1, -2, -3 and CXCL-5/LIX in P-WAT conditioned-medium is concomitant with the onset of the T2D but do not exerted a direct effect on pancreatic β-cell dysfunction.

Abstract
Obesity is a risk factor for cardiovascular disease (CVD). However, clinical research has revealed a paradoxically protective role for obesity in patients with chronic diseases including CVD, suggesting that the biological 'quality' of adipose tissue (AT) may be more important than overall AT mass or body weight. Importantly, AT is recognised as a dynamic organ secreting a wide range of biologically active adipokines, microRNAs, gaseous messengers, and other metabolites that affect the cardiovascular system in both endocrine and paracrine ways. Despite being able to mediate normal cardiovascular function under physiological conditions, AT undergoes a phenotypic shift characterised by acquisition of pro-oxidant and pro-inflammatory properties in cases of CVD. Crucially, recent evidence suggests that AT depots such as perivascular AT and epicardial AT are able to modify their phenotype in response to local signals of vascular and myocardial origin, respectively. Utilisation of this unique property of certain AT depots to dynamically track cardiovascular biology may reveal novel diagnostic and prognostic tools against CVD. Better understanding of the mechanisms controlling the 'quality' of AT secretome, as well as the communication links between AT and the cardiovascular system, is required for the efficient management of CVD.

Abstract
Metabolic syndrome and osteoporosis share similar risk factors. Also, patients with diabetes have a higher risk of osteoporosis and fracture. Liver manifestations, such as non-alcoholic steatohepatitis (NASH), of metabolic syndrome are further aggravated in diabetics and often lead to liver failure. Our objective was to create a rat model of human metabolic syndrome and determine the long-term impact of early-onset T1D on bone structure and strength in obese growing rats. Male rats were given either standard chow and RO water (Controls) or a high-fat, high-cholesterol diet and sugar water containing 55% fructose and 45% glucose (HFD). A third group of rats received the HFD diet and a single dose of streptozotocin to induce type 1 diabetes (HFD/Sz). Body weight and glucose tolerance tests were conducted several times during the course of the study. Serum chemistry, liver enzymes, and biomarkers of bone metabolism were evaluated at 10 and 28 weeks. Shear wave elastography and histology were used to assess liver fibrosis. Cancellous bone structure and cortical bone geometry were evaluated by mCT and strength by the 3-point bending method. Body mass and fat accumulation was significantly higher in HFD and HFD/Sz rats compared to Controls. Rats in both the HFD and HFD/Sz groups developed NASH, although the change was more severe in diabetic rats. Although both groups of obese rats had larger bones, their cancellous structure and cortical thickness were reduced, resulting in diminished strength that was further aggravated by diabetes. The HFD and HFD/Sz rats recapitulate MeSy in humans with liver pathology consistent with NASH. Our data provide strong indication that obesity accompanied by type 1 diabetes significantly aggravates comorbidities of MeSy, including the development of osteopenia and weaker bones. The juvenile rat skeleton seems to be more vulnerable to damage imposed by obesity and diabetes and may offer a model to inform the underlying pathology associated with the unusually high fracture rates in obese adults with diabetes.

Abstract
ABSTRACT
Animals that fast depend on mobilizing lipid stores to power metabolism. Northern elephant seals (Mirounga angustirostris) incorporate extended fasting into several life-history stages: development, molting, breeding and lactation. The physiological processes enabling fasting and lactation are important in the context of the ecology and life history of elephant seals. The rare combination of fasting and lactation depends on the efficient mobilization of lipid from adipose stores and its direction into milk production. The mother elephant seal must ration her finite body stores to power maintenance metabolism, as well as to produce large quantities of lipid and protein-rich milk. Lipid from body stores must first be mobilized; the action of lipolytic enzymes and hormones stimulate the release of fatty acids into the bloodstream. Biochemical processes affect the release of specific fatty acids in a predictable manner, and the pattern of release from lipid stores is closely reflected in the fatty acid content of the milk lipid. The content of the milk may have substantial developmental, thermoregulatory and metabolic consequences for the pup. The lactation and developmental patterns found in elephant seals are similar in some respects to those of other mammals; however, even within the limited number of mammals that simultaneously fast and lactate, there are important differences in the mechanisms that regulate lipid mobilization and milk lipid content. Although ungulates and humans do not fast during lactation, there are interesting comparisons to these groups regarding lipid mobilization and milk lipid content patterns.

Abstract
PURPOSE Obesity and metabolic syndrome (MeS) are more frequently observed in bipolar patients than the general population. This may result from the differences of adipocytokines and ghrelin levels in bipolar disorder. MATERIAL AND METHODS We evaluated the leptin, adiponectin, resistin and ghrelin levels in bipolar patients (n = 30) in manic episode and in a control group (n = 30). After treatment, the same patients were evaluated again during the euthymic episode. We also measured the insulin, glucose, insulin resistance (HOMA), trygliceride (TG), total cholesterol (TCHOL), high density lipoprotein cholesterol (HDL) and low density lipoprotein cholesterol (LDL) in relation to the (MeS). RESULTS When controlling for age, BMI and glucose, leptin levels were higher in the bipolar disorder manic episode group (BD-ME) and bipolar euthymic episode group (BD-EE) than the control group; resistin levels were higher in the BD-ME compared to the control group and it had a positive correlation with Young Mania Rating Scale (YMRS). After treatment, ghrelin levels were higher in the BD-EE compared to the BD-ME group. There was no difference among the groups with respect to adiponectin. CONCLUSIONS The present results point that high leptin, resistin and ghrelin levels may be involved in the early pathophysiological process which can lead to later obesity and MeS in patients with bipolar disorder.

Abstract
C1q/TNF-related protein 9 (CTRP9) is a paralogue of adiponectin with known favorable effects on lipid and glucose metabolism. A potential role of CTRP9 for regulation of endothelium function has been suggested by previous studies. However, no studies have examined the relation between serum CTRP9 levels and adhesion molecules in patients with type 2 diabetes mellitus (T2DM) and coronary artery disease (CAD). The present study was conducted on 337 subjects who underwent coronary angiography and were categorized into four groups according to the presence of CAD and T2DM (control, CAD, T2DM and CAD+T2DM). Serum levels of CTRP9, adiponectin, sICAM-1, sVCAM-1, sE-Selectin, IL-6 and TNF-α were measured. It was found that the circulating CTRP9 levels were independently associated with increased risk of CAD and T2DM in addition to elevated levels of serum CTRP9 in CAD, T2DM and CAD+T2DM groups. A significant association of serum CTRP9 levels with adhesion molecules in CAD and T2DM patients as well as serum TNF-α levels in CAD individuals was noted. A significant relation between the circulating levels of CTRP9 and HOMA-IR in T2DM subjects was also observed. The results revealed increased circulating levels of CTRP9 in T2DM and CAD individuals which suggests a compensatory response to insulin resistance, inflammatory milieu and endothelial dysfunction; however, more studies are needed to confirm this.

Abstract
Adiponectin is an important adipocytokine secreted chiefly by fat containing adipocytes, and plays a crucial role in glucose and lipid metabolism, inflammation and oxidative stress. Alterations in adiponectin levels have been shown to directly affect lipid and glucose metabolism that further increase the synthesis of lipids, free fatty acids and inflammatory cytokines. Changes in adiponectin levels also contribute to insulin resistance, obesity, cardiovascular diseases and type 2 diabetes. In the present review, we provide a comprehensive evaluation of the role of adiponectin and its molecular mechanisms in metabolic syndrome. Clinical improvement in adiponectin levels have been shown to positively modulate lipid and glucose metabolism, thus further substantiating its role in regulation of lipid and glucose metabolism. Currently adiponectin is being investigated as a potential therapeutic target for metabolic syndrome, although more research is required to understand the underlying mechanisms controlling adiponectin levels, including dietary and lifestyle interventions, that may target adiponectin as a therapeutic intervention in metabolic syndrome.

Abstract
OBJECTIVE Menopausal transition is usually associated with changes in body composition and a decrease in physical activity energy expenditure. Adipose tissue, especially visceral fat, is an important source of inflammatory markers, which contributes to the development of a proinflammatory state. Conversely, high levels of physical activity and exercise have an anti-inflammatory effect. This study aimed to investigate the impact of menopausal transition and physical activity on inflammatory makers. METHODS One hundred two healthy premenopausal women participated in a 5-year longitudinal study. The present secondary analyses were performed on 58 participants with a full set of data (age: 49.6 ± 1.7 y; body mass index: 23.3 ± 2.4 kg/m). Measures included body composition, waist circumference, fasting glucose and insulin levels, insulin sensitivity, plasma lipid levels, cardiorespiratory fitness, physical activity energy expenditure, and inflammatory markers. RESULTS Repeated measure analyses revealed, after the 5-year follow-up, significant increases in ferritin, interleukin-8 (IL-8), and soluble tumor necrosis factor-α receptor 1 and 2 (sTNFR1 and sTNFR2) (P < 0.001), and a significant decrease in serum high-sensitive C-reactive protein (P < 0.05). Positive correlations were observed between change (year 5 to baseline) in waist circumference and changes in high-sensitive C-reactive protein, orosomucoid (ORM), haptoglobin, and apolipoprotein B (ApoB) levels (0.26 ≤ r ≤ 0.34; P < 0.05), and between change in peripheral fat and changes in ORM, ApoB, sTNFR2 (0.28 ≤ r ≤ 0.39; P < 0.05). On the contrary, negative correlations were found between change in physical activity energy expenditure and changes in ORM as well as ApoB (r = -0.35 and r = -0.36, respectively; P < 0.05). No significant correlations were found between change in cardiorespiratory fitness, glucose, insulin, insulin sensitivity and changes in inflammatory markers. Multiple regression analyses showed that changes in physical activity energy expenditure and waist circumference together explained 23% of the individual variance of change in ORM (P < 0.05). Also, change in physical activity energy expenditure explained 15% (P < 0.05) of the variance of change in ApoB. Fat mass change explained 15% (P < 0.05) of the variance of change in IL-8, and finally change in peripheral fat explained 15% of variance of change in sTNFR2 (P < 0.05). CONCLUSIONS The present study indicates that the menopausal transition is accompanied by an increase in inflammatory markers, namely ferritin, IL-8, sTNFR1, and sTNFR2. The increase in IL-8 and sTNFR2 with menopause could be explained, in part, by changes in fat mass and peripheral fat, respectively.

Abstract
Rationale.Psoriasis is a prevalent chronic inflammatory disease with worldwide distribution affecting approximately 2% of the Caucasian population. There have been many population- and family-based studies that agree on the strong genetic component of this disease. Several studies have investigated the relationship between cytokine gene polymorphisms, psoriasis, and the occurrence of comorbidities but their data are conflicting. Objective.This study examines cytokine gene single-nucleotide polymorphisms (SNPs) in the context of psoriasis and metabolic syndrome, with a focus on the occurrence of comorbidities in psoriasis patients. The working hypothesis is that particular SNPs may predispose to an accelerated disease course and more comorbidities in psoriasis patients. Methods:This cross-sectional study was carried out in 2016 in the Dermatology Department of "Elias" University Emergency Hospital, Bucharest and included 82 psoriasis patients. Several clinical and laboratory parameters were recorded, and the presence of metabolic syndrome (MetS) was noted. Using real-time PCR, we tested for the following SNPs: rs361525, rs1800629, rs1800896, rs610604, rs17782313. Results:Disease severity was not significantly influenced by any of the five studied SNPs. Gene polymorphism of rs17782313 was found to influence the occurrence of psoriatic arthritis. In these patients, rs610604 and rs17782313 polymorphisms were associated with the presence of diabetes mellitus. Furthermore, rs17782313 influenced the presence of obesity, heterozygotes being more at risk. Our data suggested that MetS occurred independently of the five studied SNPs. Discussion.The influence of certain cytokine gene polymorphisms on multiple organ systems is justification enough for further analysis of the genetic and molecular mechanisms of metabolic syndrome development in psoriasis patients. Abbreviations:single-nucleotide polymorphisms - SNPs, metabolic syndrome - MetS.

Abstract
INTRODUCTION Psoriasis is a common, immune-mediated skin disease often associated with significant physical and psychosocial impairment. Antipsoriatic biologic agents offer patients unparalleled treatment potential in regard to greater skin clearance and overall improved quality of life. Evaluation of the therapeutic efficacy of biologic agents on the full psoriasis disease burden must account for their impact on both physical symptoms, as well as patient-reported, health-related quality of life (HRQoL) measurements. Areas covered: Results from numerous clinical trials demonstrate the significant clinical efficacy of biological agents targeting tumor necrosis factor-α (TNF-α) and the interleukin (IL)-12/23 and IL-17 immune pathways. However, relatively limited data is available evaluating their full effect on quality of life outcomes. This review will discuss the most relevant and up-to-date clinical data on HRQoL measurements related to treatment with these aforementioned biologic agents. Expert commentary: Patient-reported outcomes (i.e. Dermatology Life Quality Index) are being used with increasing frequency in clinical trials, and provide valuable information on the impact of psoriasis on numerous aspects of day-to-day living. These outcomes must also be incorporated in clinical practice, in addition to physical assessment of disease severity, treatment decisions, and therapeutic response in the psoriasis patient population.

Abstract
The aim of this study was to analyze the effects of resistance training (RT) performed with 1 or 3 sets per exercise on osteosarcopenic obesity (OSO) syndrome parameters in older women. Sixty-two older women (68.0 ± 4.3 years, 26.8 ± 4.4 kg/m2) participated in a 12-week RT program. Participants were randomly assigned into one of the three groups: two training groups that performed either 1 set (G1S, n = 21) or 3 sets (G3S, n = 20) 3 times weekly, or a control group (CG, n = 21). Body composition was assessed by dual X-ray absorptiometry, strength was evaluated by 1 repetition maximum testing. The G3S presented significantly higher strength changes than G1S. The changes for percentage of body fat were higher for G3S compared to G1S. There was no difference in skeletal muscle mass between G3S and G1S, however both training groups displayed greater increases in this outcome compared to CG. There was no effect for bone mineral density. The overall analysis indicated higher (P < 0.05) positive changes for G3S than G1S (composed Z-score: G3S = 0.62 ± 0.40; G1S = 0.11 ± 0.48). The results suggest that a 12-week RT period is effective to improve the risk factors of OSO, and that 3 sets induce higher improvements than a single set.

Abstract
Inflammatory biomarkers provide a minimally invasive means for early detection and specific treatment of metabolic syndrome and related disorders. The objective of this work was to search for inflammatory biomarkers of cardiometabolic risk in obese type 2 diabetics. The study was performed on 165 persons attending the medical outpatient clinic of Ismailia General Hospital. Their mean age was (50.69 ± 10.15) years. They were divided into three groups. The control group was composed of 55 non-obese, non-diabetic healthy volunteers, 32 males and 23 females. Two study groups were included in this study: group 2 was composed of 55 obese, non-diabetic subjects, 25 males and 30 females matched for age and gender. All patients including the control were subjected to clinical history taking, a clinical examination for the measurement of body mass index (BMI). Investigations were carried out for fasting blood glucose, fasting serum insulin, insulin resistance (IR), the lipid profile, lipoprotein band lipoprotein phospholipase A2, and non-high-density lipoprotein cholesterol (non-HDL-C). Urea, albumin and creatinine analysis and liver function tests were performed, and a complete blood count (CBC) was taken. Hemoglobin A1C (HbA1C), serum high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were tested. There were statistically significant differences among the studied groups in terms of total cholesterol, non-HDL-C, high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), lipoprotein-associated phospholipase A2 and apolipoprotein B. The inflammatory biomarkers hs-CRP, IL-6 and TNF-α were significantly statistically increased in the study groups by (1.62 ± 0.99, 2.32 ± 1.11), (1.73 ± 1.14, 2.53 ± 1.34), and (1.87 ± 1.09, 2.17 ± 0.89) respectively, where p < 0.01. Significant positive correlation was found between Homeostatic Model Assessment (HOMA)-IR, hs-CRP and IL-6. There was a significant positive correlation between non-HDL and hs-CRP, IL-6 and TNF-α and triglycerides and hs-CRP. In conclusion, in this study, CRP, IL-6, and TNF-α were significantly elevated in obese Egyptian type 2 diabetics and were positively correlated with insulin resistance, non-HDL and triglycerides. These inflammatory biomarkers could help in the premature identification of obese type 2 diabetic patients at high cardiometabolic risk. Additionally, these biomarkers are critical for providing prognostics and the validity of future potential anti-inflammatory therapeutic modalities.

Abstract
AIM The impact of fasting blood glucose levels (FBG) and disease duration on type 2 diabetes in Indian population is still unclear. The present study examines gender-dependent effects of FBG and disease duration on lipid profile, adipocytokines and related biochemical parameters in diabetic individuals. METHODS Type 2 diabetic individuals (n=100) were classified depending on FBG: patients with normal FBG (Glucose<126mg/dl) and patients with high FBG (Glucose≥126mg/dl); and disease duration: ≥0-≤3yr, >3-≤7yr, >7yr. RESULTS Males with high FBG had significantly higher serum glucose, triglycerides, very low density lipoprotein (VLDL), serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT) and waist hip ratio (WHR) than males with normal FBG. Females with high FBG had significant increase in serum glucose, adiponectin and creatinine while decrease in leptin levels than females with normal FBG. Males with high FBG had higher WHR, superoxide dismutase, SGOT, SGPT and lower adiponectin, leptin than females with high FBG. Significant positive association was observed between glucose and cholesterol, triglyceride, VLDL and urea in males with high FBG. With chronic diabetes for >7yr, males had increased systolic blood pressure, glucose, LDL, urea and low catalase activity as compared to other disease duration groups. However, females had higher adiponectin, creatinine and lower body mass index and cholesterol. CONCLUSIONS High FBG in males adversely affects lipid profile, adipocytokines and liver function. Some of these effects exacerbate as disease progresses. Higher adiponectin may have desirable effects on metabolic markers in females.

Abstract
Recent epidemiological studies have documented an inverse relationship between the decreasing prevalence of helminth infections and the increasing prevalence of metabolic diseases ("metabolic hygiene hypothesis"). Chronic inflammation leading to insulin resistance (IR) has now been identified as a major etiological factor for a variety of metabolic diseases other than obesity and Type-2 diabetes (metainflammation). One way by which helminth infections such as filariasis can modulate IR is by inducing a chronic, nonspecific, low-grade, immune suppression mediated by modified T-helper 2 (Th2) response (induction of both Th2 and regulatory T cells) which can in turn suppress the proinflammatory responses and promote insulin sensitivity (IS). This article provides evidence on how the cross talk between the innate and adaptive arms of the immune responses can modulate IR/sensitivity. The cross talk between innate (macrophages, dendritic cells, natural killer cells, natural killer T cells, myeloid derived suppressor cells, innate lymphoid cells, basophils, eosinophils, and neutrophils) and adaptive (helper T [CD4+] cells, cytotoxic T [CD8+] cells and B cells) immune cells forms two opposing circuits, one associated with IR and the other associated with IS under the conditions of metabolic syndrome and helminth-mediated immunomodulation, respectively.

Abstract
AIMS C1q/TNF-related protein-9 (CTRP9) is a novel adipokine that has been shown to promote lipid metabolism, enhance insulin sensitivity and protect against cardiovascular disease. However, previous studies in humans have produced controversial results regarding the association between CTRP9 and insulin resistance. The objective of this study was to evaluate the relationships between CTRP9 and insulin resistance in Chinese population. METHODS Subjects with normal glucose tolerance (NGT, n=108), impaired glucose tolerance (IGT, n=92), and newly diagnosed type 2 diabetes mellitus (nT2DM, n=106) were recruited to determining the circulating CTRP9 and adiponectin levels by enzyme linked immunosorbent assay. Anthropometric and biochemical measurements related to insulin resistance, adiposity and lipid profile were examined for all participants. Oral glucose tolerance test was performed in healthy subjects (17 male and 17 female). RESULTS Circulating CTRP9 level was significantly higher in both IGT and nT2DM than in individuals with NGT. Overweight/obese subjects had much higher CTRP9 levels than lean individuals, and in all subjects, females also had higher CTRP9 levels than males. In addition, circulating CTRP9 level was positively correlated with markers of obesity and insulin resistance, including body mass index, fasting blood glucose, insulin, HbA1c, homeostasis model assessment of insulin resistance and low-density lipoprotein-cholesterol, while was inversely correlated with high-density lipoprotein-cholesterol and adiponectin. Moreover, hyperglycemia during an oral glucose challenge increased circulating CTRP9 concentrations. CONCLUSIONS We conclude that CTRP9 was strongly associated with insulin resistance, suggesting that CTRP9 might be important in the development of type 2 diabetes.

Abstract
Mitochondrial dysfunction is a potentially important player in the development of insulin resistance and type 2 diabetes mellitus (T2DM). We investigated the changes of mRNA expression of genes encoding main enzymatic complexes of mitochondrial respiratory chain in subcutaneous adipose tissue (SCAT) and peripheral monocytes (PM) of 11 subjects with simple obesity (OB), 16 obese patients with T2DM and 17 healthy lean subjects (C) before and after very low-calorie diet (VLCD) using quantitative real time PCR. At baseline in SCAT, both T2DM and OB group had decreased mRNA expression of all investigated mitochondrial genes with the exception of 2 complex I (NDUFA 12) and complex IV (COX 4/1) enzymes in OB subjects. In contrast, in PM only the expression of complex I enzymes NDUFA 12 and MT-ND5 was reduced in both T2DM and OB subjects along with decreased expression of citrate synthase (CS) in T2DM group. Additionally, T2DM subjects showed reduced activity of pyruvate dehydrogenase and complex IV in peripheral blood elements. VLCD further decreased mRNA expression of CS and complex I (NT-ND5) and II (SDHA) enzymes in SCAT and complex IV (COX4/1) and ATP synthase in PM of T2DM group, while increasing the activity of complex IV in their peripheral blood elements. We conclude that impaired mitochondrial biogenesis and decreased activity of respiratory chain enzymatic complexes was present in SCAT and PM of obese and diabetic patients. VLCD improved metabolic parameters and ameliorated mitochondrial oxidative function in peripheral blood elements of T2DM subjects but had only minor and inconsistent effect on mitochondrial gene mRNA expression in SCAT and PM.

Abstract
PURPOSE Preeclampsia is a multisystem disorder and its etiology remains still unclear. Recent hypotheses rely on imbalance between angiogenic and antiangiogenic factors and disruption of endothelial function of spiral arteries. In addition; increased VTE (venous thromboembolism) risk is still unclear in preeclampsia. Our aim was to investigate the relationship between endothelial dysfunction, adipocytokines, platelet function, and vasculogenesis in preeclampsia. METHODS Plasma angiogenic (PlGF, VEGF), antiangiogenic factors (sflt-1, endoglin) with adipocytokines (leptin, adiponectin, ghrelin), endothelial dysfunction markers (vWF, NO), and platelet function markers (ADP and collagen induced platelet aggregation, P-selectin) were examined in 30 early-onset, 22 late-onset preeclampsia, and 27 healthy pregnants. Enzyme-linked immunosorbent assay (ELISA) was used to determine the serum biomarker levels except NO. NO levels were determined using colorimetric method. RESULTS Endoglin, leptin, and vWF levels were increased in preeclampsia (P < 0.001), whereas PlGF, P-selectin (P < 0.001), and col-induced platelet aggregation slope (P < 0.05) were decreased in the same counterpart as compared to healthy pregnants. Endoglin also correlated with sflt-1 in preeclamptic patients. CONCLUSION Increase in the levels of antiangiogenic factors and leptin herewith decline in the level of other angiogenic factor PlGF, did not affect nitric oxide and platelet aggregation markers significantly. Increased levels of vWF and endoglin might be result of endothelial dysfunction, so our findings suggest that an impaired angiogenesis may address endothelial dysfunction, but not platelet aggregation for preeclampsia.

Abstract
Adipose tissue represents a critical component in healthy energy homeostasis. It fulfills important roles in whole-body lipid handling, serves as the body's major energy storage compartment and insulation barrier, and secretes numerous endocrine mediators such as adipokines or lipokines. As a consequence, dysfunction of these processes in adipose tissue compartments is tightly linked to severe metabolic disorders, including obesity, metabolic syndrome, lipodystrophy, and cachexia. While numerous studies have addressed causes and consequences of obesity-related adipose tissue hypertrophy and hyperplasia for health, critical pathways and mechanisms in (involuntary) adipose tissue loss as well as its systemic metabolic consequences are far less understood. In this review, we discuss the current understanding of conditions of adipose tissue wasting and review microenvironmental determinants of adipocyte (dys)function in related pathophysiologies.

Analysis of the association of leptin and adiponectin concentrations with metabolic syndrome in children: Results from the IDEFICS study. Nutr Metab Cardiovasc Dis 2017; 27:543-551. [PMID: 28511904 DOI: 10.1016/j.numecd.2017.04.003] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2017] [Revised: 03/20/2017] [Accepted: 04/08/2017] [Indexed: 12/19/2022]
Abstract
BACKGROUND AND AIMS Adipokines may play a role in the pathogenesis of the metabolic syndrome (MetS) in children. We aimed to evaluate the association of leptin, adiponectin, and its ratio (L/A ratio) with the metabolic syndrome (MetS) in a subsample of the IDEFICS (Identification and prevention of Dietary- and lifestyle-induced health EFfects In Children and infantS) cohort. METHODS AND RESULTS Leptin, adiponectin and MetS parameters were measured in a subsample of 1253 children (3-9.9 years) participating to the IDEFICS study, grouped as: Non-OW (underweight/normal weight) and OW/Ob (overweight/obese). MetS was defined using the sex- and age-specific cut-offs based on the distribution of MetS components in the IDEFICS cohort. The prevalence of the MetS among OW/Ob was 24.8% and 27.1% in boys and girls respectively, whereas ≤2% among Non-OW. OW/Ob had significantly higher leptin and L/A ratio as compared to Non-OW. Significantly higher leptin was found in OW/Ob with MetS as compared with OW/Ob without MetS. Significantly lower adiponectin was observed only in OW/Ob girls as compared to Non-OW. A 1SD increase in leptin and L/A ratio z-scores or a 1SD decrease in adiponectin z-score were significantly associated with higher risk of MetS. After adjustment for BMI or body fat mass (BFM) the association remained significant only for leptin. CONCLUSION We showed that in European children, higher leptin concentration is associated with MetS, even after adjusting for BMI or BFM, confirming an early role of leptin in MetS, while the association of adiponectin with MetS seems be mediated by body fat in this age range.

Abstract
Obesity and in particular the excessive visceral fat distribution is accompanied by several alterations at hormonal, inflammatory and endothelial level. These alterations induce a stimulation of several other mechanisms that contribute to the hypertensive state and on the other side to increase the cardiovascular morbidity. In these chapter we will examine the main mechanisms of obesity and obesity-related hypertension and in particular the role of sympathetic nervous system, the alterations of the renal function and at the microvascular level. We will also depict the role of insulin resistance as factor stimulating and potentiating the other mechanisms. The second part will be focalized on the major target organ damage linked with obesity and obesity-related hypertension. We will finally describe the management and treatment of obesity and the antihypertensive drug therapies more effective in hypertensive obeses.

Abstract
Context: KDT501 is an isohumulone drug that has demonstrated beneficial effects on metabolic parameters in mice. Objective: This study was intended to examine potential improvements in metabolism in humans. Design and Setting: Changes in carbohydrate and lipid metabolism, along with inflammatory markers, were evaluated in prediabetic humans in a clinical research center. Participants: Nine obese patients participated. All had prediabetes or normal glucose tolerance plus three features of metabolic syndrome. Intervention: All participants were treated with escalating doses of KDT501 to a maximum dose of 1000 mg every 12 hours for a total of 28 days. Outcome Measures: Changes in carbohydrate metabolism were measured with oral glucose tolerance, homeostatic model of insulin resistance, and euglycemic clamp; changes in plasma lipids and response to a lipid tolerance test; and changes in plasma inflammatory markers. Results: The drug was well tolerated. After KDT501 treatment, plasma triglycerides were reduced at 4 hours during a lipid tolerance test. Furthermore, plasma adiponectin and high-molecular-weight adiponectin increased significantly, and plasma tumor necrosis factor-α decreased significantly. There were no significant changes in oral glucose tolerance test results or insulin sensitivity measures. Conclusions: Despite the small sample size and the short duration of therapy, KDT501 administration reduced measures of systemic inflammation and improved postmeal plasma triglyceride levels, which may be beneficial in participants with insulin resistance or metabolic syndrome.

Abstract
Skeletal muscle mitochondrial dysfunction, evidenced by incomplete beta oxidation and accumulation of fatty acid intermediates in the form of long and medium chain acylcarnitines, may contribute to ectopic lipid deposition and insulin resistance during high fat diet (HFD)-induced obesity. The present review discusses the roles of anterograde and retrograde communication in nucleo-mitochondrial crosstalk that determines skeletal muscle mitochondrial adaptations, specifically alterations in mitochondrial number and function in relation to obesity and insulin resistance. Special emphasis is placed on the effects of high fat diet (HFD) feeding on expression of nuclear-encoded mitochondrial genes (NEMGs) nuclear receptor factor 1 (NRF-1) and 2 (NRF-2) and peroxisome proliferator receptor gamma coactivator 1 alpha (PGC-1α) in the onset and progression of insulin resistance during obesity and how HFD-induced alterations in NEMG expression affect skeletal muscle mitochondrial adaptations in relation to beta oxidation of fatty acids. Finally, the potential ability of acylcarnitines or fatty acid intermediates resulting from mitochondrial beta oxidation to act as retrograde signals in nucleo-mitochondrial crosstalk is reviewed and discussed.

Abstract
Gestational weight gain (GWG) is an important modifiable factor known to influence fetal outcomes including birth weight and adiposity. Unlike behaviors such as smoking and alcohol consumption, the effect of GWG throughout pregnancy on fetal development and other outcomes has not been extensively studied. The aim of this study was to investigate the relationship of GWG with endocrine factors such as adiponectin, leptin, and C-reactive protein which may be associated with inflammatory response, fetal growth, and adiposity later in life. Data were obtained from the Ulm Birth Cohort Study (UBCS) and the Ulm SPATZ Health Study, two methodologically similar birth cohort studies including newborns and their mothers recruited from 11/2000–11/2001 and 04/2012–05/2013. In the two included birth cohorts we consistently observed statistically significant positive associations between GWG beginning as early as the second trimester with fetal cord blood leptin and stronger association beginning as early as the first trimester with post-delivery maternal serum leptin. Total weight gain exceeding commonly accepted recommended guidelines was consistently associated with higher leptin levels in both cord blood and post-delivery maternal serum. These results suggest a potential pathomechanistic link between fetal environment and surrogate markers of long-term health.

Abstract
Brain-derived neurotrophic factor (BDNF) is a neurotrophin, which plays an important role in the central nervous system, and systemic or peripheral inflammatory conditions, such as acute coronary syndrome and type 2 diabetes mellitus (T2DM). BDNF is also expressed in several nonneuronal tissues, and platelets are the major source of peripheral BDNF. Here, we reviewed the potential role of BDNF in platelet reactivity in T2DM and its association with selected inflammatory and platelet activation mediators. Besides that, we focused on adipocytokines such as leptin, resistin, and adiponectin which are considered to take part in inflammation and both lipid and glucose metabolism in diabetic patients as previous studies showed the relation between adipocytokines and BDNF. We also reviewed the evidences of the antidiabetic effect of BDNF and the association with circulating inflammatory cytokines in T2DM.

Correlations between serum adipocytokine concentrations, disease stage, radiological status and total body fat content in the patients with primary knee osteoarthritis. INTERNATIONAL ORTHOPAEDICS 2016; 41:983-989. [PMID: 28013331 DOI: 10.1007/s00264-016-3370-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2016] [Accepted: 12/04/2016] [Indexed: 10/20/2022]
Abstract
PURPOSE The study was designed to investigate whether serum concentrations of leptin, resistin and adiponectin in obese and normal-weight patients with primary knee osteoarthritis (OA) correlate with clinical and radiological stages of the disease and percentage of total body fat. METHODS Seventy-three patients with knee OA, divided into obese and normal-weight groups, were clinically evaluated according to the Knee Society Score (KSS), and radiologically assessed using Kellgren and Lawrence scale. The percentage of total body fat and some anthropometric data were also given. Serum leptin, resistin and adiponectin concentrations were measured by Elisa and were correlated with the clinical, radiological and anthropometric parameters. RESULTS Leptin concentrations were significantly higher (p = 0.001) in the obese patients and positively correlated (R = 0.63) with radiologically assessed OA grade, but only in the normal-weight group. Resistin and adiponectin concentrations were identical in obese and normal-weight patients and negatively correlated (R = -0.41) with the clinical status of obese patients. In both groups, percentage of total body fat positively correlated (R = 0.29 and R = 0.53 for obese and normal-weight respectively) with radiologically assessed OA grade. However, no correlations were found with clinical status of the patients. CONCLUSIONS It was found that in the obese patients with knee OA, increased percentage of total body fat and elevated serum leptin concentration might favour the advancement of clinical but not radiologically assessed changes in the joint structures, while in normal-weight patients it correlates only with radiologically assessed changes but does not affect to an appreciable extent the clinical status of the patients.

Abstract
OBJECTIVE To investigate the association of maternal serum levels of chemerin, retinol binding protein-4 (RBP-4), and visfatin with gestational diabetes mellitus (GDM). MATERIAL AND METHODS 158 pregnant women were screened between 24 and 28 weeks of gestation. They were divided into two groups: GDM group (n=76) and control group (n=82). Maternal serum concentrations of chemerin, RBP-4, visfatin, insulin, and homeostasis model assessment-insulin resistance (HOMA-IR) were assessed. RESULTS There were no differences in age and gestational age between the GDM group and the control group (p=0.058 and p=0.820, respectively). Body mass index (BMI) at 24 to 28 weeks of gestation was higher in the GDM group (p<0.001). The serum concentrations of RBP-4, chemerin, and visfatin did not demonstrate significant differences between the GDM and control groups (p=0.871, p=0.100, and p=0.886, respectively). Significant differences in serum level of insulin and HOMA-IR were found between the GDM and control groups (14.94 vs 9.87, p<0.001 and 3.73 vs 1.77, p<0.001, respectively). Correlation analyses of chemerin, RBP-4, visfatin, insulin, and HOMA-IR in both groups revealed a weak degree of positive correlation between RBP-4 and chemerin (Spearman r=0.251, p=0.026) and a strong positive correlation between maternal insulin and HOMA (Spearman r=0.868, p<0.001). CONCLUSION No differences were found in serum chemerin, RBP-4, and visfatin between pregnant women with GDM and healthy pregnant women. Further prospective studies will be essential to elucidate the contribution of adipokines to GDM and the positive correlation between maternal RBP-4 and chemerin.
