Abstract Background:The pathogenesis of type 2 diabetes mellitus is due to two major abnormalities including insulin resistance and dysfunction, which lead to the inability to regulate blood glucose level. Adiponectin is a hormone secreted by the adipose tissue and it takes part in glucose metabolism with insulin-sensitising properties. Low levels of adiponectin leads to reduction of fatty acid oxidation decreased glucose uptake in skeletal muscle cells and increased level of free fatty acids leading to insulin resistance. Leptin is another adipokine produced by adipose tissue involved in the control of food intake via its action on the hypothalamus, suppressing appetite and stimulating energy expenditure. Leptin plays a critical role in pathophysiology of type 2 diabetes mellitus.The aim of the study was to investigate the association of serum adipokines levels with glycemic control and metabolic dyslipidemia in Sudanese patients with type 2 diabetes mellitus.Methods: This was a case control study. 202 patients with type 2 diabetes and 102 non-diabetic controls participated after signing written consent. Weight (kg) and height (m) were measured thenthe body mass index (kg/m2) was determined. Blood samples were collected after an overnight fasting. FBG, HbA1c and lipid profiles were measured using enzymatic methods. Adiponectin and leptin were measured using sandwich ELISA.Results: Adiponectin concentrations was significantly lower in patients with type 2 diabetes compared with the controls (p<0.001) and it was inversely correlated with HbA1c (Pearson Correlation -.160, P value = 0.005), total cholesterol and LDL levels (P = 0.05) and direct correlated HDL levels (P = 0.05). Leptin concentrations was significantly higher in patients with type 2 diabetes compared with the controls (p<0.002) and it was positively correlated with HbA1c (Pearson Correlation .155, P value = 0.02), total cholesterol and LDL levels (P = 0.05), there were no correlation with HDL and TG levels. Patients had significantly higher fasting blood glucose, HbA1c levels, total cholesterol and LDL levels compared with the controls. Conclusion: Patients with type 2 diabetes mellitus had decreased levels of serum adiponectin, high levels of serum leptin. There were significant correlations found between adiponectin and leptin levels with glycemic control and metabolic dyslipidemia

Introduction: Diabetes mellitus (DM) is a non-communicable disease that has increased from year to year. Type 2 diabetes mellitus is not caused by lack of insulin secretion, but is caused by the failure of the body's cells to respond to the hormone insulin (insulin resistance). Insulin resistance was found to be a major contributor to atherogenic dyslipidemia. Dyslipidemia in DM risks 2 to 4 times higher than non-DM. Although dyslipidemia has a great risk for people with type 2 diabetes mellitus, this conventional risk factor only explains a portion (25%) of excess cardiovascular risk in type 2 DM. Discussion: In uncontrolled type 2 DM patients, LDL oxidation occurs faster which results from an increase in chronic blood glucose levels. Glycemic control as a determinant of DM progressivity is determined through HbA1c examination. HbA1c levels are associated with blood triglyceride levels. Meanwhile, triglyceride levels are associated with total cholesterol and HDL cholesterol levels. HbA1c levels are also associated with LDL cholesterol levels. Conclusion: There is a relationship between lipid profile and the progression of type 2 diabetes mellitus.   Keywords: type 2 diabetes mellitus, dyslipidemia, HbA1c, glycemic control, lipid profile

Type 2 diabetes mellitus (T2DM) is a metabolic disorder characterized by hyperglycemia due to insufficient secretion or action of insulin.Elevated oxidative stress and diminished antioxidants may play an important role to develop T2DM and its complications. Aldose reductase (AR) enzyme plays a key role in the reduction of glucose to sorbitol by Polyol pathway. To estimate the AR activity and malondialdehyde (MDA) levels and in patients with T2DM. In this case-control study, a total number of 60 subjects (30 T2DM and 30 age-matched controls) wererecruited.Fasting blood sugar (FBS), Post-Prandial blood sugar (PPBS), AR activity and MDA levels were estimated in all the subjects. The AR activity was estimated by nicotinamide adenine dinucleotide phosphate hydrogen (NADPH) oxidation method. The plasma MDA levels were estimated by the thiobarbituric acid reactive substance (TBARS) method. For Statistical analysis, all the data were compared between the two groups by using unpaired t-test. Pearson correlation coefficient was calculated among T2DM. A P value <0.05 was considered as statistically significant for all data analyzed. The mean of FBS, PPBS, AR activity, and MDA levels were found significantly high in T2DM as compared to controls (P<0.001, P<0.001, P<0.001, P<0.001, respectively). A significant positive correlation was found between FBS and PPBS among T2DM (r=0.71, P<0.01). However, There was no significant correlation found between AR activity and MDA level among T2DM (r=0.002, P>0.05). Results showed thatthe mean of FBS, PPBS, AR activity, and MDA levels were found significantly higher in T2DM than controls. There was no significant correlation found between AR activity and MDA level among T2DM.

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 present study investigates the encapsulated propolis on blood glycemic control, lipid metabolism, and insulin resistance in type 2 diabetes mellitus (T2DM) rats. The animal characteristics and biological assays of body weight, fasting blood glucose (FBG), fasting serum insulin (FINS), insulin act index (IAI), triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were measured and euglycemic hyperinsulinemic glucose clamp technique were used to determine these effects. Our findings show that oral administration of encapsulated propolis can significantly inhibit the increasing of FBG and TG in T2DM rats and can improve IAI and M value in euglycemic hyperinsulinemic clamp experiment. There was no significant effects on body weight, TC, HDL-C, and LDL-C in T2DM rats treated with encapsulated propolis. In conclusion, the results indicate that encapsulated propolis can control blood glucose, modulate lipid metabolism, and improve the insulin sensitivity in T2DM rats.

The article provides a review of the literature on the possibilities of using various indices of insulin resistance in type 2 diabetes (T2DM) treatment. The main mechanisms of insulin resistance and its role in the formation of type 2 diabetes mellitus and other metabolic disorders are described. The main indices of insulin resistance, used in real clinical practice nowadays, are considered. Methods of their calculation are given. The effect of metformin and incretin active medications on insulin resistance is described. It was shown that the combination of these medications improves tissue sensitivity to insulin in patients with T2DM. Standard indicators for assessing glycemic control, such as fasting glucose and glycosylated hemoglobin (HbA1c), do not reflect the patient’s lipid metabolism. The use of insulin resistance assessment indices in patients with type 2 diabetes mellitus allows both, exercising glycemic control, and the metabolic disorders, often associated with carbohydrate metabolism disorders, monitoring. Using insulin resistance indices, it is possible to select the optimal treatment regimen for type 2 diabetes mellitus for a particular patient, to predict and evaluate the effectiveness of treatment in dynamics. Simple, generally available laboratory indicators and anthropometric data are used to calculate the indices of insulin resistance, and they are easy to measure. In this regard, the use of insulin resistance indices is possible in routine clinical practice.
