Introduction: Diabetes mellitus (DM) is a metabolic disorder occurring due to either defect in the secretion of insulin or defect in the action of insulin characterized by hyperglycemia. Hyperglycemia causes oxidative stress due to increased production of mitochondrial Reactive oxygen species (ROS) in T2DM. Ceruloplasmin (Cp) acts as an antioxidant through its ferroxidase activity. There is an association between the raised serum Cp levels and elevated plasma glucose levels in Type-2 Diabetes mellitus (T2DM) patients. Aim and objectives: The aim of this study is to evaluate the correlation between the fasting plasma glucose (FPG), 2hour plasma glucose (2hPG), and serum Cp level in T2DM patients as compared to non diabetics. Materials and methods: 165 cases of T2DM were recruited along with the 40 healthy age and sex matched controls. The blood samples were analyzed for serum Cp and FPG and 2hPG after 75-gram oral glucose. Results: The serum Cp levels of the patient group with T2DM were significantly higher than the control group (p = 0.000). There was a significant positive association between serum Cp level and 2hPG level of the patient population (r = 0.283, p = 0.000), but there was no significant correlation found between serum Cp levels and fasting plasma glucose levels in patients (r = 0.146, p =0.061). Similar findings were seen in the sub group analysis. Conclusion: Our study concludes a significant positive correlation between serum Cp and 2hPG levels in T2DM patients. Hence Cp levels may be considered as a part of the routine diagnostic panel to assess diabetes mellitus.

Type 2 diabetes mellitus is characterized by shorter leukocyte telomere length, but the relationship between leukocyte telomere length and type 2 diabetes mellitus development is rather questioned. Fasting and post-load glycaemia associated with different types of insulin resistance and their relation with leukocyte telomere length remains unknown. We compared leukocyte telomere length and fasting or post-load glucose levels in persons who do not receive glucose lowering treatment. For 82 randomly selected rural residents of Ukraine, aged 45+, not previously diagnosed with type 2 diabetes mellitus, the WHO oral glucose tolerance test and anthropometric measurements were performed. Leukocyte telomere length was measured by standardized method of quantitative monochrome multiplex polymerase chain reaction in real time. Spearman’s or Pearson’s rank correlation was used for correlation analysis between fasting plasma glucose or 2-h post-load plasma glucose levels and leukocyte telomere length. Logistical regression models were used to evaluate risks of finding short or long telomeres associated with fasting plasma glucose or 2-h post-load plasma glucose levels. No association of fasting plasma glucose and leukocyte telomere length was revealed, whereas 2-h post-load plasma glucose levels demonstrated a negative correlation ( P < 0.01) with leukocyte telomere length. Waist circumference and systolic blood pressure were negatively related ( P = 0.03) with leukocyte telomere length in men. Oral glucose tolerance test result-based glycemic categories did not show differences between mean leukocyte telomere length in categories of normal fasting plasma glucose and 2-h post-load plasma glucose (NGT, n = 33); diabetes mellitus (DM), n = 18 and impaired fasting glucose/tolerance (IFG/IGT, n = 31) levels. A correlation relationship between leukocyte telomere length and 2-h post-load plasma glucose level in NGT; IFG/IGT and DM groups ( P = 0.027; 0.029 and 0.049, respectively) was revealed; the association between leukocyte telomere length and fasting plasma glucose was confirmed in DM group only ( P = 0.009). Increase of 2-h post-load plasma glucose (but not fasting plasma glucose) level improves the chances of revealing short telomeres: OR 1.52 (95% CI 1.04–2.22), P = 0.03. After the adjustment for age, gender, waist circumference, systolic blood pressure, and fasting plasma glucose, these phenomena remain significant. We conclude that 2-h post-load plasma glucose but not fasting plasma glucose is inversely associated with leukocyte telomere length. Impact statement • Contradictory epidemiologic data have been obtained about the link between the leucocyte telomere length (LTL) and diabetes. Type 2 diabetes (T2D) is likely to be pathophysiologically heterogeneous, but comparison of the association of LTL separately with fasting plasma glucose (FPG) and 2-h post-load plasma glucose (2hPG) levels has not been done before. Thus, the study of LTL changes associated with different types of hyperglycaemia, that largely determine the heterogenity of T2D is important. • In a population-based study of rural Ukrainians, we were the first to demonstrate that the increase of 2hPG (but not FPG) level increases the chances of revealing short telomeres. • The obtained data can help to clarify the relationship between the LTL shortening and different conditions of the insulin resistance (mainly liver resistance in high FPG and mostly muscle and adipose tissue resistance in high 2hPG).

ObjectivesAbout 11%–30% of individuals with impaired fasting plasma glucose (IFG) have type 2 diabetes mellitus (T2DM), diagnosed by the 75 g oral glucose tolerance test (75 g OGTT). This study investigated (1) the prevalence and cut-off levels for fasting plasma glucose (FPG) and glycated haemoglobin A1c (HbA1c) in IFG individuals that most effectively predict the presence of T2DM diagnosed by a 75 g OGTT; (2) the predictors associated with T2DM; and (3) the pathophysiological characteristics of patients with IFG.Materials and methodsA single-centre, cross-sectional study was conducted in a primary care setting. A standard 75 g OGTT was performed on 123 subjects with IFG. Their beta-cell function and insulin resistance were calculated through plasma glucose and insulin levels monitored during the 75 g OGTT.ResultsIn the IFG subjects, the prevalence of T2DM using the 2-hour postload plasma glucose (2hPG) criterion was 28.5%. Pre-diabetes and normal glucose metabolism were found in 48.7% and 22.8%, respectively, by 75 g OGTT. An HbA1c level ≥6.0% or FPG ≥5.9 mmol/L were the optimal cut-off thresholds for the prediction of the presence of T2DM. HbA1c had a sensitivity of 76.7% and specificity of 55.7% (95% CI 57.7% to 90.1% and 95% CI 43.3% to 67.6%, respectively), while FPG had a sensitivity of 85.7% and specificity of 23.9% (95% CI 69.7% to 95.2% and 95% CI 15.4% to 34.1%, respectively). The presence of metabolic syndrome, a higher HbA1c and higher FPG levels were associated with the risk of T2DM in the Thai IFG population.ConclusionsAlmost one-third of the people with IFG had T2DM diagnosed by the 2hPG criterion. HbA1c was more effective than FPG in predicting the presence of T2DM in the IFG subjects. IFG individuals with HbA1c≥6.0% or FPG≥5.9 mmol/L should be advised to undergo a 75 g OGTT to detect T2DM earlier than otherwise.

<p><strong>Background:</strong> Type 2 diabetes mellitus is a serious chronic disease with microvascular complications such as retinopathy, nephropathy and neuropathy and macrovascular complications such as cardiac, peripheral arterial and cerebrovascular disease. <strong>Objective:</strong> The aim of the study was to investigate the value of HbAlc as a diagnostic test for type 2 diabetes mellitus in Bangladeshi inclividuals. <strong>Methods:</strong> This cross sectional study was conducted in the Department of Biochemis­try, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh. A total 657 patients, who were attended in the one point sample collection centre of Bangabandhu Sheikh Mujib Medical University for oral glucose tolerance test (OGIT) from 1st April 2014 to 30th June 2014, were purposively enrolled in this study. According to WHO criteria and based on OGIT findings study subjects were categorized into Normoglycemic (257), IFG (82), IGT (174), and DM (347). Fasting plasma glucose. HbA1c and plasma glucose at 2 hour after glucose load on OGIT was done from all the study subjects. <strong>Results:</strong> With a cut-off value of 6.J %, HbAlc had a maximal sensitivity and specificity of 97.0% and 49.0% respectively with a positive predictive value 65.5% and a negative predictive value 94.0%. HbA1c had a sensitivity of 93.0% and a specificity of 63.0% was calculated with a cut-off value of 6.5% with positive predictive value 77.5% and negative predictive value 90.0%. Both fasting plasma glucose levels and 2 hour plasma glucose levels were showed significant positive correlation with HbAlc (r = 0.788, P = 0.000 and r = 0.800, P = 0.000 respectively). <strong>Conclusion:</strong> The study suggests that measurement of HbAlc could be used to make diagnosis of T2DM in the Bangladeshi population.</p>

Abstract Background The pathogenesis of spontaneously diabetic Otsuka Long-Evans Tokushima Fatty (OLETF) rats, among the best models for human type 2 diabetes mellitus (T2DM), remains poorly defined. Therefore, we investigated the dynamic changes in taurine-conjugated bile acids (T-BAs) and intestinal microbiota during T2DM development in OLETF rats. Methods OLETF rats and corresponding diabetes-resistant Long Evans Tokushima Otsuka (LETO) rats were fed a normal baseline diet. The progress of T2DM was divided into four phases, including normal glycemia-normal insulinemia (baseline), normal glycemia-hyperinsulinemia, impaired glucose tolerance, and DM. Body weight, liver function, blood lipids, fasting plasma glucose, fasting plasma insulin, fasting plasma glucagon-like peptide (GLP)-1 and GLP-2, serum and fecal T-BAs, and gut microbiota were analyzed during the entire course of T2DM development. Results There were reductions in fecal T-BAs and short-chain fatty acids (SCFAs)-producing bacteria including Phascolarctobacterium and Lactobacillus in OLETF rats compared with those in LETO rats at baseline, and low levels of fecal T-BAs and SCFAs-producing bacteria were maintained throughout the whole course of the development of T2DM among OLETF rats compared with those in corresponding age-matched LETO rats. Fecal taurine-conjugated chenodeoxycholic acid correlated positively with Phascolarctobacterium. Fecal taurine-conjugated deoxycholic acid correlated positively with Lactobacillus and fasting plasma GLP-1 and inversely with fasting plasma glucose. Conclusion The fecal BAs profiles and microbiota structure among OLETF rats were different from those of LETO rats during the entire course of T2DM development, indicating that reductions in intestinal T-BAs and specific SCFA-producing bacteria may be potential mechanisms of T2DM in OLETF rats.
