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.

Objective: This study aimed to determine whether the antidiabetic effects of puguntano (Curanga fel-terrae [Lour.]) extract involve anti-inflammatory effects mediated through adiponectin receptors (AdipoRs). Methods: Type 2 diabetes mellitus (T2DM) Wistar rats were induced by a combination of high-fat diet for 5 weeks and injection small dose streptozotocin 30 mg/kg bw/rat. This study was conducted in 48 T2DM rats, which were randomly assigned into two weight-matched groups (n=24, each). Only the treatment group received 0.2 mg/g bw of puguntano extract suspension through oral for 10 days. The clinical characteristics of T2DM and AdipoR were assessed before and after the treatment period. Results: The treatment group demonstrated significantly lower body weight, fasting blood glucose, and homeostasis model assessment-insulin resistance (HOMA-IR) but higher AdipoR than the control group (all, p<0.001). Furthermore, there were also negative correlations between AdipoR to body weight and HOMA-IR (all, p<0.05). Conclusion: Our data suggest that puguntano could improve glucose metabolism and ameliorate insulin resistance and have anti-inflammatory effects mediated through AdipoR in T2DM.

Introduction: Type 2 Diabetes Mellitus (T2DM) is a multifactorial pathological condition associated with insulin resistance and insulin deficiency. Uric acid and calcium have shown inconsistent association with occurrence of diabetes. Aim: To evaluate the role of uric acid and calcium in development of T2DM. Materials and Methods: This was a case-control study conducted in Department of Biochemistry from March to November 2019 in Sriram Chandra Bhanja, Medical College and Hospital, Cuttack, Odisha, India. A 180 subjects undertaken with the objective of finding any association of serum uric acid and calcium with insulin and its resistance in newly diagnosed T2DM cases. Newly diagnosed T2DM patients were taken as cases. Age and sex matched healthy individuals were taken as controls. Fasting Plasma Glucose (FPG), serum insulin, serum uric acid and ionised calcium were measured in autoanalyser and insulin resistance was calculated using Homeostasis Model Assessment for Insulin Resistance (HOMA- IR). Other confounding risk factors for T2DM like Body Mass Index (BMI), family history was taken into account. Results: A significant positive correlation of serum uric acid with serum insulin (p=0.029) and its resistance (p=0.032) in cases. Serum calcium was negatively associated with insulin and its resistance in both cases and controls. Regression models showed serum uric acid as a strong independent risk factor for levels of insulin and its resistance. Conclusion: The findings of the study showed that regular evaluation of serum uric acid and calcium should be done in those who are at risk of developing T2DM. Larger prospective studies will be required for definite assessment.

Abstract Background Adiponectin is associated with improved systemic insulin sensitivity and profound positive effects in adipose tissue, such as increasing mitochondrial density in adipocytes, reducing adipocyte size, and effective esterification of free fatty acids on lipid storage The factor performs forward transcriptional regulation. Diabetes and its complications are considered to be one of the main causes of morbidity and mortality worldwide. Objectives The aim of this study was to correlate serum levels of adiponectin with insulin resistance in Sudanese males' type 2 diabetes mellitus. Methodology: A case-control community-based study carried out among 126 patients with T2DM as cases group (mean ages 45.2 ± 5.4 years); and 126 normal healthy individuals as controls group (mean ages 44.7 ± 5.4 years as) in Aldaraga Diabetic Center, Wad Medani, Gezira State, Sudan. About Five mL of fasting venous blood was obtained from all participants. HbA1c, FPG, FPI, serum Adiponectin, and (HOMA)-IR were analyzed. SPSS (v 20.0) was used for data analysis. Results The mean of serum adiponectin in the cases group (3.03 ± 0.90µg/ml) was lower than the control group (6.02 ± 4.24µg/ml) giving highly significant differences -between them (P = value ≤ 0.000). HbA1c and Homeostasis Model Assessment of Insulin Resistance index (HOMA-IR) differed significantly between the two groups (P-value ≤ 0.000). Serum adiponectin concentrations correlated significantly negative with HOMA IR (r = -0.149, P-value = 0.002). Conclusion We concluded that low plasma adiponectin level was predictive of future development of Insulin resistance in Sudanese males.

Background. Diabetes and obesity are very common associated metabolic disorders that are linked to chronic inflammation. Leptin is one of the important adipokines released from adipocytes, and its level increases with increasing body mass index (BMI). Tumor necrosis factor alpha (TNF-α) is a cytokine that is released by adipocytes and inflammatory cells in response to chronic inflammation. Type 2 diabetes mellitus (T2DM) is believed to be associated with low-grade chronic inflammation. The current study aims to investigate the involvement of leptin and TNF-α in T2DM associated with obesity. Methodology. This is a cross-sectional study involving 63 healthy volunteers and 65 patients with T2DM. Body composition was measured, and fasting venous blood samples were analyzed for blood glucose, glycosylated hemoglobin (HbA1c), basal insulin, leptin, and TNF-α. HbA1c was measured by the affinity column method. Insulin, leptin, and TNF-α immunoassays were performed by the ELISA technique. Insulin resistance and beta-cell function were assessed using the homeostasis model assessment (HOMA-IR and HOMA-B). Results. Our study showed a significantly higher level of TNF-α in T2DM patients compared to controls (7.51 ± 2.48 and 6.19 ± 3.01, respectively; p=0.008). In obese diabetic patients, the serum level of TNF-α was significantly higher in comparison with nonobese diabetic patients (p<0.018) and obese nondiabetic group (p<0.001). TNF-α correlated positively with HbA1c (r = 0.361, p=0.003) and HOMA-IR (r = 0.296, p=0.017) in patients with T2DM. Conclusion. TNF-α is associated with concurrent obesity and T2DM and correlates with HbA1c. This suggests that TNF-α needs further investigation to explore if it has a role in monitoring the effectiveness of management in individuals with obesity and T2DM.

Abstract Background: This study was conducted to determine the effect of Rheum ribes supplementation on glycemic indices and apolipoproteins in patients with type 2 diabetes mellitus (DMT2).Methods: In this randomized controlled trial, sixty type 2 diabetic patients, aged 30-60 years with body mass index (BMI) of 20-30 kg/m 2 , and hemoglobin A1c (HbA1c) of 6-8% were included. The patients were randomly assigned to receive 450 mg of Rheum ribes aqueous extract (AG), 450 mg of Rheum ribes ethanolic extract (EG) or placebo (PG), three times daily for 6 weeks. Then glucose, the homeostatic model assessment (HOMA-IR and HOMA-B) and apolipoprotein A-I (ApoA1) and apolipoprotein B (ApoB) were measured.Results: According to these findings, in the AG and EG intervention groups, we observed a significant reduction in serum levels of insulin (P=0.003 and P=0.001, respectively), HOMA-IR (P=0.01 and P=0.001, respectively) and HOMA-B (P=0.002 and P=0.001, respectively) indices, without no significant changes in glucose. There was also a significant reduction in serum levels of ApoB (P=0.006 and P=0.03, respectively) and ApoB/ApoA1 ratio (P=0.016 and P=0.04, respectively) in both AG and EG. Intervention in both AG and EG had increasing effects on ApoA1 (P=0.08 and P=0.05, respectively). None of these variables had a significant change in PG. At the end of study, there were significant differences in insulin (P=0.04), HOMA-IR (P=0.03), HOMA-B (P=0.01), ApoB (P=0.02), and ApoB/ApoA1 (P=0.03) ratio among groups.Conclusions: Rheum ribes intake may have favorable effects on insulin resistance and apolipoproteins in diabetic patients.Trial registration: The study was recorded in Iranian Registry of Clinical Trials under the registration number of IRCT201410142709N31 (Registration date: 2014-12-11, https://en.irct.ir/trial/2543 ).

Abstract. The pro-oncogenic effects of obesity, insulin resistance and hyperinsulinemia have been proven in some types of cancer, as well as in type 2 diabetes mellitus. The objective of the research was to investigate the state of insulin resistance in patients suffering from oncological diseases and to compare insulin correlations in patients with type 2 diabetes mellitus and those with cancer. Materials and Methods. The study included the following groups of patients: Group I included healthy individuals (the control group); Group II comprised patients with type 2 diabetes mellitus; Group ІІІ included patients with cancer: subgroup IIIa comprised patients with breast cancer, subgroup IIIb included patients with endometrial cancer, subgroup IIIс comprised patients with colorectal cancer. Fasting blood glucose was determined by glucose oxidase method; hemoglobin A1c was determined by ion exchange chromatography; the levels of insulin and insulin-like growth factor-1 were determined by immune-enzyme method. Insulin resistance was assessed by the homeostatic model assessment for insulin resistance index. The results obtained were analyzed using statistical analysis. Results. Obesity was confirmed in all the groups of patients with cancer. Significantly higher body mass index, as compared to the control group, was found in patients with endometrial cancer (p = 0.008). In comparison with the control group, the levels of insulin and insulin-like growth factor-1 increased significantly in all groups of patients with cancer (p < 0.001). Fasting blood sugar levels and hemoglobin A1c did not differ from the indicators in the control group (p > 0.05). Direct correlations between insulin and body mass index (p < 0.05), insulin-like growth factor-1 (p < 0.05) and the homeostatic model assessment for insulin resistance index in patients of Group II and Group III were detected (p < 0.05). Conclusions. In obese patients with breast, uterine and colorectal cancer, there was found a decrease in insulin sensitivity, which might increase the proliferative effects of insulin and insulin-like growth factor-1. Correlation analysis showed a probable association of cancer and diabetes mellitus due to obesity and insulin resistance.

OBJECTIVE: To investigate the relationship between the circulating level of active ghrelin and abdominal adiposity, serum levels of insulin or insulin resistance in patients with type 2 diabetes mellitus. DESIGN: We measured the plasma levels of the active form of ghrelin in 18 obese and 18 nonobese patients with type 2 diabetes mellitus using a radioimmunoassay (RIA) kit. Body fat accumulation was measured by computed tomography (CT) and insulin resistance by the glucose infusion rate (GIR) during an euglycemic hyperinsulinemic clamp study. RESULTS: Plasma levels of ghrelin in obese patients with type 2 diabetes mellitus were significantly decreased compared with nonobese patients. There were significant correlations between the plasma levels of ghrelin and BMI (r=-0.505, P<0.01), visceral (r=-0.444, P<0.01), subcutaneous (r=-0.506, P<0.01) and total (r=-0.534, P<0.01) fat area, serum levels of insulin (r=-0.513, P<0.01) or GIR (r=0.478, P<0.01) in type 2 diabetic patients. The plasma level of ghrelin was significantly associated with serum levels of insulin (F=8.468, P<0.05) or GIR (F=8.522, P<0.05) after adjustment for BMI in patients with type 2 diabetes mellitus. CONCLUSIONS: Decreased plasma levels of active ghrelin are significantly associated with abdominal adiposity, hyperinsulinemia and insulin resistance in type 2 diabetic patients. Hyperinsulinemia associated with insulin resistance may suppress plasma levels of active ghrelin in patients with type 2 diabetes mellitus.

Background: Serum ferritin is known as an index for body iron stores also as an inflammatory marker and it is influenced by several disease. We were looking for a correlation between HbA1c and S. Ferritin in type 2 DM. Methodology: The present study a total of 150 participants were enrolled of which 100 were confirmed cases of Type 2 Diabetes Mellitus and rest 50 age and sex matched healthy subjects constituted the control group. All were screened for HbA1c, Fasting blood sugar, Post prandial blood sugar and S.Ferritin. Results: A highly significant variation and positive correlation was observed with respect to S.Ferritin and HbA1c levels. Mean S.Ferritin was high in the subgroup with poor glycemic control. Conclusion: The fasting, post prandial sugar levels, HbA1c and S.Ferritin were significantly higher in the diabetic subjects. This study shows a positive correlation between HbA1c and S. Ferritin levels. So we can conclude that in diabetic patients S. Ferritin may serve as an independent marker of poor glycemic and metabolic control. Keywords: Serum ferritin, Type 2 Diabetes Mellitus, HbA1c.

AbstractOver the last few decades, Mizoram has shown an increase in cases of type 2 diabetes mellitus; however, no in-depth scientific records are available to understand the occurrence of the disease. In this study, 500 patients and 500 healthy controls were recruited to understand the possible influence of their dietary and lifestyle habits in relation with type 2 diabetes mellitus. A multivariate analysis using Cox regression was carried out to find the influence of dietary and lifestyle factors, and an unpaired t test was performed to find the difference in the levels of biochemical tests. Out of 500 diabetic patients, 261 (52.3%) were males and 239 (47.7%) were females, and among the control group, 238 (47.7%) were males and 262 (52.3%) were females. Fermented pork fat, Sa-um (odds ratio (OR) 18.98), was observed to be a potential risk factor along with tuibur (OR 0.1243) for both males and females. Creatinine level was found to be differentially regulated between the male and female diabetic patients. This is the first report of fermented pork fat and tobacco (in a water form) to be the risk factors for diabetes. The unique traditional foods like Sa-um and local lifestyle habits like tuibur of the Mizo population may trigger the risk for the prevalence of the disease, and this may serve as a model to study other populations with similar traditional practices.

Abstract Background Serum wnt1-induced signaling pathway protein 1 (WISP1) levels are increased with obesity, which is a common complication associated with lower extremity atherosclerotic disease (LEAD). However, to date, the relationship between elevated WISP1 levels and the incidence of lower extremity atherosclerotic disease (LEAD) in type 2 diabetes mellitus (T2DM) remains unclear. Methods 174 newly diagnosed type 2 diabetic patients were enrolled in our study. Patients were divided into two groups, LEAD group (n=100) and control group (n=74). Anthropometric parameters, blood pressure and some biochemical parameters were obtained. Body composition was detected by bioelectrical impedance analysis (BIA). Levels of serum insulin were determined by radioimmunoassay. Serum WISP1 and interleukin 6 (IL-6) levels were determined using an enzyme-linked immunosorbent assay. Results It was shown that serum WISP1 levels in diabetic patients with LEAD were higher than those without LEAD (P<0.001). Serum WISP1 levels were positively related with waist circumference (r=0.237, P=0.003), waist-hip ratio (r=0.22, P=0.006), visceral fat area (r=0.354, P<0.001), serum creatinine (r=0.192, P=0.012), interleukin 6 (r=0.182, P=0.032), c-reactive protein (r=0.681, P<0.001), triglycerides (r=0.119, P<0.001), fasting glucose (r=0.196, P=0.011), glycated hemoglobin (r=0.284, P<0.001), and HOMA-IR (r=0.285, P<0.026). Compared with the lowest tertile, the odds ratio of the middle tertile for LEAD incidence was 3.27 (95% CI, 1.24–8.64) and 4.46 (95% CI, 1.62–12.29) for the highest tertile after adjusting confounding factors. Conclusion The results suggest that increased serum WISP1 levels independently contribute to the incidence of LEAD in patients with newly diagnosed T2DM.
