Abstract Background Reduced skeletal muscle has been suggested as a potential risk factor for type 2 diabetes mellitus (T2DM). Serum creatinine is the primary metabolite of creatine in skeletal muscle. Therefore, low serum creatinine levels may be associated with an increased risk of T2DM. We aimed to evaluate the association between serum creatinine levels and the risk of T2DM in Korea. Methods We analyzed a total of 264,832 nondiabetic adults older than 40 years of age who had undergone a national health examination at least once from 2009 to 2015 in the Korean National Health Insurance Service Cohort. Hazard ratios for T2DM were calculated. Results In men, serum creatinine levels and the risk for T2DM showed an inverse J-shaped association. This association was confirmed after adjustment for age, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), and fasting plasma glucose. In women, there was a trend that serum creatinine levels were inversely associated with the risk of T2DM among those with serum creatinine below 1.1 mg/dl. However, serum creatinine levels were not significantly associated with the risk of T2DM after adjustment for age, BMI, SBP, DBP, and fasting plasma glucose. Conclusions Reduced levels of serum creatinine were significantly associated with an increased risk of T2DM in men with creatinine below 1.20 mg/dl. There was a trend that decreased levels of serum creatinine were associated with an increased risk of T2DM among women with serum creatinine below 1.1 mg/dl, although this result was not statistically significant.

Abstract Reduced skeletal muscle has been suggested as a risk factor for type 2 diabetes mellitus (T2DM). Serum creatinine is used as a surrogate for muscle mass. Therefore, low serum creatinine levels may be associated with an increased risk of T2DM. We aimed to evaluate the association between serum creatinine levels and the risk of T2DM. We analyzed a total of 264,832 nondiabetic adults in Korea. In men, serum creatinine levels and the risk for T2DM showed an inverse J-shaped association even after adjustment for age, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), and fasting plasma glucose. In women, there was a trend that serum creatinine levels were inversely associated with the risk of T2DM among those with serum creatinine below 1.1 mg/dl. However, serum creatinine levels were not significantly associated with the risk of T2DM after adjustment for age, BMI, SBP, DBP, and fasting plasma glucose. Reduced levels of serum creatinine were significantly associated with an increased risk of T2DM in men with creatinine below 1.20 mg/dl. There was a trend that decreased levels of serum creatinine were associated with an increased risk of T2DM among women, although this result was not statistically significant.

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.

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.
