AbstractThe present study aimed to evaluate the diagnostic value of echocardiography in measuring the thickness of epicardial adipose tissue (EAT) of the patients of type 2 diabetes mellitus (T2DM) and its correlation with the intimal-medial thickness of the carotid artery (cIMT) to investigate the relationship between EAT and cIMT. 68 patients of T2DM were enrolled and were divided into 2 groups: group of T2DM with duration≤10 years (35 cases) and group of T2DM with duration>10 years (33 cases). And 30 healthy subjects were enrolled as the control group. The thickness of EAT and cIMT were measured by echocardiography and high-frequency ultrasonography. The thickness of EAT and IMT of the carotid artery of 2 type 2 diabetic groups (duration≤10 years and>10 years) were significantly higher than that of the control group (all p<0.05), and the thickness of EAT and cIMT of the group of T2DM with duration>10 years were significantly higher than that of the group of T2DM with duration≤10 years (p<0.05). In univariate analysis, the thickness of EAT was positively and significantly associated with age (r=0.412, p<0.05), BMI (r=0.566, p<0.05), waist circumference (r=0.475, p<0.05), LDL (r=0.425, p<0.05), TG (r=0.496, p<0.05), duration of diabetes (r=0.384, p<0.05) and cIMT (r=0.456, p<0.05). In multiple stepwise regression analyses, age, BMI and IMT of carotid artery were appeared to be significantly associated with EAT (p<0.05 for all). In conclusion, routine screening of EAT and cIMT by ultrasonography in type 2 diabetic patients helps us to predict cardiovascular risks and prevent further development of cardiovascular complications.

Soluble Cd163

Monocyte/macrophage-specific soluble CD163 (sCD163) concentration is associated with insulin resistance and increases with deteriorating glycemic control independently of BMI. This led to the proposal of the hypothesis that obesity-associated white adipose tissue inflammation varies between individuals. The objective was to examine the effect of male overweight/obesity and type 2 diabetes mellitus (T2DM) on associations between adiposity parameters and sCD163. A total of 23 overweight/obese non-diabetic men, 16 overweight/obese men with T2DM, and a control group of 20 normal-weight healthy men were included. Body composition and regional body fat distribution were determined by whole-body dual X-ray absorptiometry scan and abdominal computed tomography (CT) scan. Serum sCD163 concentrations were determined by ELISA. Associations between adiposity parameters and sCD163 were investigated using multiple linear regression analysis. In the normal-weight healthy men, there was no significant association between adiposity parameters and sCD163, whereas in the overweight/obese non-diabetic men, measures of general and regional adiposity were positively associated with sCD163. In the overweight/obese men with T2DM, only visceral adipose tissue (VAT) and the ratio of VAT to abdominal subcutaneous adipose tissue (SAT), a measure of relative body fat distribution between VAT and SAT depots, were positively associated with sCD163. In a multivariate analysis, including VAT, upper-body SAT, and lower-body fat, adjusted for BMI and age, VAT remained a significant predictor of sCD163 in the overweight/obese T2DM men, but not in the overweight/obese non-diabetic men. Our results indicate that VAT inflammation is exaggerated in men with T2DM, and that propensity to store excess body fat viscerally is particularly detrimental in men with T2DM.

ABSTRACT The AIM of the present study was to find and compare the correlations between somatotype and some anthropological parameters in Bulgarian male patients with type 2 diabetes mellitus. PATIENTS AND METHODS: Anthropometric measurements were taken from 165 male patients with type 2 diabetes mellitus. All patients were ethnic Bulgarians. They were divided into two age groups: a 40-60-year group (58 patients, mean age 52.05 ± 0.73 yrs), and a 61-80-year group (111 patients, mean age 68.02 ± 0.53 yrs). The controls were allocated into similar agematched groups. Direct anthropometric measurements were body height and weight, biepicondylar breadth of the humerus and biepicondylar breadth of the femur. Circumferential measurements were taken from the relaxed and contracted upper arm, the forearm, the waist, the hip, the thigh and the medial calf. Skin folds were measured below the inferior angle of the scapula, above the X rib, above the crista iliaca, at the abdomen, triceps brachii, forearm, thigh and the medial calf. The components of human somatotype according to the criteria of Heath-Carter, body mass index (ВМІ) and waist-to-hip ratio (WHR) were calculated. RESULTS: We found very strong positive correlations (РС > 0.70) between ВМI and the endomorphic and mesomorphic components of somatotype in 40-60-year-old male diabetic patients. The correlation between the endomorphic and mesomorphic components of somatotype and the anthropometric measurements characterizing the central accumulation of adipose tissue (waist circumference, hip circumference, WHR) was very strong positive (РС = 0.5-0.7). Male diabetic patients aged 61-80 years: we found a very strong positive correlation between endomorphic and mesomorphic components and ВМІ, a strong correlation between these components and the waist circumference, and a good correlation between the components and the circumferences of the waist and hip and WHR. CONCLUSIONS: In male patients with type 2 diabetes aged 40-60 years, the endomorphic and mesomorphic components of somatotype are strongly positively correlated with the parameters which characterize the total adipose tissue accumulation in the human body (ВМІ). There is a good positive correlation between the two components of somatotype and the parameters showing visceral adipose tissue accumulation (circumferences of waist, hip, thigh and WHR). In male patients with type 2 diabetes aged 61-80 years we found a strong positive correlation of the endomorphic and mesomorphic components of somatotype with BMI and a good positive correlation with the circumferences of the waist, hip, thigh and WHR.

This review deals with the role of adipose tissue inflammation (ATI) in the development of type 2 diabetes mellitus (DM2). ATI is regarded as a link between obesity and DM2. The review illustrates the involvement of main adipokines in pathogenesis of DM2 and provides a detailed description of such factors as impaired adiponectin and stimulation of cytokine production responsible for metabolic disorders, activation of lipolysis, in adipocytes, increased fatty acid and triglyceride levels, suppression of insulin activity at the receptor and intracellular levels. Adipokines, in the first place cytokines, act on the insulin signal pathway and affect the intracellular inflammatory kinase cascade. At the intercellular level, ATI stimulates JNK and IKK-beta/kB responsible for the development of insulin resistance via such mechanisms as activation of cytokine secretion in the adipose tissue, oxidative stress, and induction of endoplasmic reticulum enzymes. The key role of JNK and IKK-beta/kB in the inhibition of the insulin signal pathway is mediated through inactivation of insulin receptor substrate 1. Also, it is shown that ATI modulates B-cell function and promotes progressive reduction of insulin secretion.

Background: Adipose tissue produces pro-inflammatory mediators involved in the atherosclerotic process. We investigated whether 12-month exercise training in patients with type 2 diabetes mellitus and coronary artery disease would reduce circulating levels and genetic expression of mediators in the interleukin-18, Caspase-1 and NLR pyrin domain containing 3 pathways. Correlations to glucometabolic variables; fasting glucose, HbA1c, duration of diabetes, insulin, C-peptide, insulin resistance (measured by homeostatic model assessment indexes – insulin resistance) and body mass index at baseline were further assessed. Methods: 137 patients (aged 41–81 years, 17.2% female participants) were included and randomized to a 12-month exercise programme or to a control group. Fasting blood and adipose tissue samples were taken at inclusion and after 12 months. Results: No statistically significant difference in changes of any variable between the intervention and the control group was found. At baseline, a positive correlation between insulin and homeostatic model assessment indexes – insulin resistance, interleukin-18 expression in adipose tissue and an inverse correlation between some glucometabolic variables and leukocyte expression of NLR pyrin domain containing 3 and Caspase-1 were observed. Conclusion: No significant effects of long-term exercise training were observed on the inflammasome-related mediators in our patients with combined coronary artery disease and type 2 diabetes mellitus. The observed correlations may indicate a pro-inflammatory state in adipose tissue by overweight and a compensatory downregulation of these mediators in circulating leucocytes.

The Relationship

Abstract Introduction and aim Cardiovascular diseases remain the most common cause of morbidity and mortality in patients with diabetes. Epicardial adipose tissue (EAT), visceral fat depot of the heart, was found to be associated with coronary artery disease in cardiac and non-cardiac patients. Increased visceral adiposity is associated with proinflammatory activity, impaired insulin sensitivity, increased risk of atherosclerosis and high mortality. In the present study we aimed to investigate the relationship between EAT and visceral adiposity index (VAI) in patients with diabetes. Methods This was a cross-sectional study involving 128 patients with type 2 diabetes mellitus (73 females, 55 males; mean age, 54.09+±+9.17 years) and 32 control subjects (23 females, 9 males; mean age, 50.09+±+7.81 years). EAT was measured by using a trans-thoracic echocardiograph. Parameters such as waist circumference (WC), body mass index (BMI), triglyceride and high density lipoprotein (HDL) cholesterol were used to calculate VAI. Result EAT and VAI measurements were significantly higher in patients with diabetes when compared to control subjects. In the bivariate correlation analysis, VAI was positively correlated with uric acid level (r=0.214, p=0.015), white blood cell count (r= 0.262, p=0.003), platelet count (r=0.223, p=0.011) and total cholesterol levels (r= 0.363, p<0.001). Also, VAI was found to be the independent predictor of EAT. Conclusion Simple calculation of VAI was found to be associated with increased EAT in patients with type 2 diabetes.
