This paper deals with the combination therapy of patients in the early stages of development of the metabolic syndrome (MS) according to the results of the survey and the 6-month treatment of 54 patients aged 20 to 55 years with a BMI ≥25 kg / m2 and signs of abdominal obesity. In the control group 15 of the surveyed persons with a BMI < 25,0 kg/m2 at age 20 to 50 years were included . According to the classification proposed in the recommendations of the experts of GFCF for the diagnosis and treatment of MS (2009), MS source in the group of patients with a BMI ≥ 25 kg/m2 was determined in 94.2% of cases. In this study the authors used laboratory examination, including general and biochemical blood tests to determine the level of glycated hemoglobin (Hb A1c), the concentration of magnesium and malondialdehyde (MDA) in serum levels of C-peptide immuno-reactive insulin (IRI) to the calculation of indices: HOMO IR, characterizing insulin resistance (IR) and Caro, which characterizes the degree of impairment of glucose uptake. The instrumental methods were measurement of blood pressure by auscultatory method, ECG, echocardiography, ultrasound of the abdomen, CGMS-monitoring of blood glucose levels. According to the obtained data in the studied group of patients with a BMI of 25 kg/m2 statistically significant increase in blood pressure, severe insulin resistance with compensatory hyper-insulinemia, elevated levels of Hb A1c were identified. It is established that the formation of overweight in 68.5% of cases is accompanied by hypomagnesemia and activation of oxidative stress". It was confirmed by statistically significant increase in MDA content. Number of newly diagnosed diseases - hypertension, ischemic heart disease, diabetes type 2, NAFLD, patients with a BMI ≥ 25 kg/m2 was significantly higher than the con-trol, which confirms the dominant influence of overweight as a risk factor for CVD formation with impaired metabolism of glucose and lipids. To study the stages of development of MS in both groups of patients oral glu-cose tolerance test (PGT) was conducted. According to the obtained results, the patients of the studied group were divided into 3 subgroups (without carbohydrate metabolism, with IGT, with newly diagnosed type 2 diabe-tes). In the 1st subgroup concentrations of insulin and C-peptide at 30 min of the test was higher than in other subgroups and the control group, but this concentration was decreased to 120 minute test. In the 2nd subgroup of these indicators for 30 minutes were significantly lower and grew to 120 minute test. In the subgroup with newly diagnosed type 2 diabetes, this concentration of insulin and C-peptide at 30 min of the test was lower than in the control group, but the concentration was increased to 120 minute test. Monitoring blood glucose lev-els using the CGMS system helped to identify: in the 1st subgroup intermittent episodes of hyperglycemia to 5.5% daily time; significant episodes of hyperglycemia in the 3rd subgroup – 19% of the time during the day. Therefore, the first stage of correction of hyper-insulinemia and IR were: changing the receiving regime of low-calorie food and incretin mimetics appointment - exenatide. At the same time, the patients in the treatment group received drugs magnesium – Magnesium Orotate (if hypomagnesemia) and antioxidants – coenzyme Q10 and vitamin E. After 24 weeks of therapy, clinical examination demonstrated the effectiveness of treat-ment: BMI statistically significantly decreased by 8.5%, IL by 43.3%, normalization of the level of glycated hemoglobin and reduced levels of atherogenic lipids, as well as the achievement of target values of blood pressure on average for the study group were identified. Restoring the sensitivity of insulin receptors was accompanied by an increase in the level of magnesium in the blood by 47.5% and a simultaneous decrease in activity of oxidative system by 42.7%. The obtained results suggest the usefulness of the use of incretin mimetics drugs with antioxidant activity and therapy by preparations of magnesium in the prevention and treatment of MS in the early stages of development.

Background: Musclin is a newly identified skeletal muscle–derived secretory factor, which has been recently characterized as a stimulator that induces insulin resistance in mice. However, the pathophysiological role of musclin in humans remains poorly understood. The aim of this study was to explore the potential correlations between musclin plasma levels and various metabolic parameters in patients with type 2 diabetes mellitus. Materials and methods: In this hospital-based study, plasma samples were collected from the enrolled individuals, including 38 newly diagnosed, treatment-naive type 2 diabetes mellitus patients and 41 age- and gender-matched control subjects. Plasma musclin levels were examined by radioimmunoassay. Results: Compared with the control group, musclin plasma levels were significantly higher in untreated type 2 diabetes mellitus patients. Musclin levels in the plasma of newly diagnosed type 2 diabetes mellitus patients were positively correlated with fasting plasma glucose, haemoglobin A1c, serum insulin, triglycerides and homeostasis model assessment of insulin resistance. Furthermore, multivariate logistic regression analysis showed that the level of musclin was associated with the presence of type 2 diabetes mellitus. Receiver operating characteristic curve analysis yielded an area under the curve for musclin of 0.718 in type 2 diabetes mellitus. Conclusion: The circulating concentration of musclin was significantly increased in type 2 diabetes mellitus patients. Our results suggest that musclin has a strong relationship with insulin resistance in type 2 diabetes mellitus.

Background/Aims: Long non-coding RNAs (lncRNAs) have emerged as key players in several biological processes and complex diseases. The risk of type 2 diabetes (T2D) is determined by a combination of environmental factors and genetic susceptibility. The purpose of this study was to identify aberrant lncRNAs involved in T2D pathogenesis. Methods: Microarray analysis was performed using whole blood samples from patients newly diagnosed with T2D and healthy controls. Pathway and Gene Ontology (GO) analyses were utilized to annotate the target genes. Coding non-coding co-expression (CNC) analysis was performed to construct a co-expression network. Results: We found 55 lncRNAs and 202 mRNAs were differentially expressed in the T2D group compared to the healthy control group. Pathway and GO analyses demonstrated that dysregulated mRNAs were mainly associated with immune regulation, inflammation, and insulin resistance, whereas CNC analysis identified 10 pairs of co-expressed lncRNA-mRNAs in our patient cohort (R > 0.99). Furthermore, expression of the top three upregulated lncRNAs in the T2D group was correlated with measures of glycometabolism (P < 0.05). Conclusion: This study identified aberrantly expressed lncRNAs and mRNAs in Han Chinese patients with T2D, and demonstrated that dysregulated lncRNAs may have roles in T2D pathogenesis through regulation of inflammation and insulin resistance.

ObjectiveMany studies have shown that low sex hormone-binding globulin (SHBG) is associated with insulin resistance, but only few studies have examined how serum SHBG is regulated by insulin in humans. This interventional study aimed to investigate the effect of insulin therapy (IT) on serum SHBG levels in newly diagnosed type 2 diabetic patients.MethodsA total of 80 newly diagnosed type 2 diabetic subjects were enrolled and randomly grouped into a 2-week intensive IT with/without metformin. Serum SHBG, total testosterone, glucose, liver enzymes, lipids, insulin, and C-peptide levels were measured before and after IT.ResultsBefore IT, serum SHBG levels were negatively correlated with BMI, waist circumference (WC), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (γ-GT), triglyceride (TG), fasting insulin, and C-peptide, and homeostatic model assessment of insulin resistance (HOMA-IR), and positively with HDL-C (all P for trend <0.05), after adjustment for age and sex. IT increased serum SHBG levels from 26.5±14.5 to 33.2±15.0 nmol/l (P<0.001), increased by 25.2% (95% CI, 20.3 to 30.9%, P<0.001). In a multiple linear regression model adjusting for age, sex, BMI, and WC, the decreases in ΔALT (standardized regression coefficient β=−0.374, P=0.012) and ΔTG (β=−0.380, P=0.020) were independent contributors to the increase in ΔSHBG.ConclusionsIT increases serum SHBG likely through improving insulin resistance and liver function.

Background. Cathepsin D has been recently implicated in insulin resistance and cardiovascular disease. This study was designed to investigate the relationship between cathepsin D and newly diagnosed type 2 diabetes. Methods. Circulating cathepsin D levels and metabolic variables were measured in 98 cases and 98 controls. Myocardial performance index “Tei index” that reflects both left ventricular systolic and diastolic function was measured with Doppler echocardiography in cases. Results. Newly diagnosed type 2 diabetes demonstrated significantly higher circulating cathepsin D concentrations than controls (median level: 227 ng/ml versus 174 ng/ml, P<0.01). In newly diagnosed type 2 diabetes, a significant correlation was found between cathepsin D levels and HOMA-IR (homeostatic model assessment of insulin resistance) (r=0.25, P=0.01). In contrast, no significant correlation was found between cathepsin D levels and clinical parameters in the control group (all P>0.05). Interestingly, correlation analysis revealed a positive association between cathepsin D levels and Tei index in type 2 diabetes (r=0.22, P=0.03). Conclusions. Increased levels of circulating cathepsin D are closely linked with the presence of type 2 diabetes, and cathepsin D might serve as a novel biomarker for cardiac dysfunction in newly diagnosed type 2 diabetes.

Abstract Background Recent studies have shown that dysfunction and decrease of regulatory T cells (Tregs) correlates with insulin resistance (IR), one of the most significant mechanisms for type 2 diabetes mellitus (T2DM). To examine potential relationships among Tregs, IR, blood lipid content, and related cytokines, we investigated the frequency of CD4+CD25+Foxp3+ Tregs, as well as expression levels of interleukin 10 (IL-10) and transforming growth factor-β (TGF-β) in newly diagnosed T2DM patients. Methods Fifty-one newly diagnosed T2DM patients and 55 control individuals were enrolled. According to body mass index (BMI), the T2DM patients were grouped into non-obese and obese groups. Blood was collected in ethylene diamine tetraacetic acid (EDTA) anticoagulant tubes for detection of CD4+CD25+Foxp3+ Tregs by flow cytometry. Serum was collected to quantify IL-10 and TGF-β levels by enzyme-linked immunosorbent assay (ELISA). By comparing percentages of Tregs between non-obese and obese groups, correlation with Treg frequency, homeostasis model assessment of insulin resistance (HOMA-IR), IL-10 and TGF-β was examined. Results The percentage of CD4+CD25+Foxp3+ Tregs in the newly diagnosed T2DM group was significantly lower than in the control group (P<0.01). Further, levels of IL-10 and TGF-β were also lower in the T2DM group (P<0.05). The level of IL-10 was remarkably lower in the obese group than in the non-obese and the control groups (P<0.01), but there was no significant difference between non-obese group and the control group. The level of TGF-β was lower in obese group than in the control group (P<0.05). There was no significant difference between non-obese group and the control group. The frequency of CD4+CD25+Foxp3+ Tregs in the obese group was significantly lower than in the non-obese group (P<0.05). In the obese group, the percentage of Tregs negatively correlated with HOMA-IR and positively correlated with TGF-β (P<0.05). There was no obvious correlation between Treg and HOMA-IR in the non-obese group. Conclusion The percentage of CD4+CD25+Foxp3+ Tregs and levels of related cytokines IL-10 and TGF-β were precipitously decreased in newly diagnosed T2DM patients. Therefore, the function of Tregs in limiting the proinflammatory milieu represents an important pathogenic mediator of the development of obesity-induced IR in newly diagnosed T2DM patients. Notably, TGF-β may play an important role in this process. Thus, enhancing expression of Tregs may improve IR in newly diagnosed T2DM patients with obesity.

Metabolic surgery is the most efficacious method for the treatment of morbid obesity and was recently included among the antidiabetes treatments recommended in obese type 2 diabetes (T2D) patients. The aim of this study was to compare in a randomized controlled trial the effect of sleeve gastrectomy (SG) to that of intensive lifestyle intervention plus pharmacologic treatment on some markers of insulin resistance and beta cell function as well as some appetite controlling hormones in a group of male obese T2D subjects. The study groups comprised 20 subjects for SG and 21 control subjects. Fasting blood glucose, insulin, proinsulin, adiponectin, leptin, ghrelin, HOMA-IR, HOMA-%B, proinsulin-to-insulin ratio and proinsulin-to-adiponectin ratio were evaluated at baseline and after one year follow-up. Overall, patients in the SG group lost 78.98% of excess weight loss (%EWL) in comparison with 9.45% in the control group. This was accompanied by a significant improvement of insulin resistance markers, including increase of adiponectin and decrease of HOMA-IR, while no changes were recorded in the control group. Weight loss was also associated with a significant improvement of proinsulin-to-insulin and proinsulin-to-adiponectin ratio, both surrogate markers of beta cell dysfunction. These also improved in the control group, but were only marginally significant. Our findings suggest that improved insulin resistance and decreased beta cell dysfunction after sleeve gastrectomy might explain diabetes remission associated with metabolic surgery.

Abstract Background In patients with type 2 diabetes mellitus (T2DM) the inflammatory and metabolic responses to epigallocatechin-3-gallate (EGCG) are unknown. Objectives Evaluate the impacts of EGCG on metabolic factors and some biomarkers of stress oxidative in patients with T2DM. Methods In this randomized, double-blind, placebo-controlled trial, 50 patients with T2DM consumed either 2 tablets (300 mg) EGCG (n=25) or wheat flour as placebo (n=25) for 2 months. The total antioxidant capacity (TAC), interleukin-6 (IL-6), lipid profile, mean arterial pressure (MAP), atherogenic index of plasma (AIP) were evaluated before and after the intervention. Results The finding of present study exhibited a significant increase in the serum levels of TAC after the EGCG supplementation (p=0.001). Also, in compare with control group, the mean changes of TAC were significantly higher in supplement group (p=0.01). In intervention group, a significant decrease was observed in the mean levels of triglyceride, total cholesterol, diastolic blood pressure (DBP), AIP, and MAP (p<0.05). Taking EGCG resulted in the mean changes of total cholesterol, MAP and DBP were significantly lower in compare with control group (p<0.05). Conclusions This study recommended that EGCG supplementation may be improved blood pressure, lipid profile, AIP, and oxidative status in patients with T2DM.

Introduction. Insulin resistance is a well-known leading factor in the development of metabolic syndrome. The aim of this study was to evaluate metabolic effects of metformin added to sulfonylurea in unsuccessfully treated type 2 diabetic patients with metabolic syndrome. Material and methods. A group of thirty subjects, with type 2 diabetes, secondary sulfonylurea failure and metabolic syndrome were administered the combined therapy of sulfonylurea plus metformin for six months. Metformin 2000 mg/d was added to previously used sulfonylurea agent in maximum daily dose. Antihypertensive and hypolipemic therapy was not changed. The following parameters were assessed at the beginning and after six months of therapy: glycemic control, body mass index, waist circumference, blood pressure, triglycerides, total cholesterol and its fractions, homeostatic models for evaluation of insulin resistance and secretion (HOMA R, HOMA B) and C- peptide. Results. Glycemic control was significantly improved after six months of the combined therapy: (fasting 7.89 vs. 10.61 mmol/l. p<0.01; postprandial 11.12 vs. 12.61 mmol/l. p<0.01, p<0.01; glycosylated hemoglobin 6.81 vs. 8.83%. p<0.01). the body mass index and waist circumference were significantly lower (26.7 vs. 27.8 kg/m2, p<0.01 and 99.7 vs. 101.4 cm for men, p<0.01; 87.2 vs. 88.5 for women, p<0.01). Fasting plasma triglycerides decreased from 3.37 to 2.45 mmol/l (p<0.001) and HOMA R from 7.04 to 5.23 (p<0.001). No treatment effects were observed on blood pressure, cholesterol, and residual insulin secretion. Conclusion. Administration of metformin in type 2 diabetes with metabolic syndrome decreased cardiovascular risk factors by reducing glycemia, triglycerides, BMI, central obesity and insulin resistance.

Gamma-oryzanol is a component of rice bran oil (RBO) with purported health benefits. This study evaluated the effects of gamma-oryzanol on insulin resistance and lipid metabolism in Wistar rats with type 2 diabetes (T2DM). The rats were divided into three groups and consumed one of the following diets for 5 weeks: 15 % soybean oil (control group); 15 % palm oil (PO); and 15 % PO with the addition of 5.25 g gamma-oryzanol (POO). The results showed that PO markedly increased plasma low-density-lipoprotein cholesterol, plasma triglycerides, and hepatic triglyceride levels, but did not reduce the area under the curve for glucose and insulin significantly, compared with the control group. Adding gamma-oryzanol to PO improved the negative influence of PO on lipid metabolism in T2DM rats. In addition, gamma-oryzanol tended to increase insulin sensitivity in T2DM rats compared to control and PO groups. Longer-term studies are needed to evaluate these effects further.
