Effects of Sequential Treatment Based on Lina/MET After Short-term Intensive Insulin in Newly Diagnosed Type 2 Diabetes

Short-term intensive insulin therapy(SIIT) is able to reverse ? cell dysfunction and induce glycemic remission in patients with newly diagnosed type 2 diabetes. However, proportion of patients with response gradually decreases over time. There is no consensus on which treatment should be given in order to maintain the benefit in glycemic control and ? cell recovery. In this multi-center, randomized, controlled study, effects of various sequential treatments ( metformin, linagliptin and combined with both drugs) on long-term blood glucose control as well as preservation of ? cell function after SIIT were investigated. In total, 448 patients with newly diagnosed type 2 diabetes who meet the inclusive criteria will be enrolled in eight centers in China. After baseline assessments, all patients will be treated with insulin pump to achieve and maintain euglycemia for 2 weeks. After completion of intensive treatment, insulin pump will be stopped. Different treatments will be applied to patients for 48 weeks according to randomization: Group A: Linagliptin 5 mg Qd + Metformin 0.5 g bid; Group B: Linagliptin 5 mg Qd; Group C: Metformin 0.5 g bid; Group D: No oral drugs. Primary endpoint is proportion of patients achieving glycosylated hemoglobin A1C <7% at the end of the study. Secondary endpoints include proportion of patients achieving glycosylated hemoglobin A1C <6.5% at the end of study; differences in ?-cell function , insulin sensitivity, GLP-1 and glucagon secretion among treatment groups, and differences in adverse events among treatment groups.

Effects of Niacin on Intramyocellular Fatty Acid Trafficking in Upper Body Obesity and Type 2 Diabetes Mellitus

Muscle insulin resistance is a hallmark of upper body obesity (UBO) and Type 2 diabetes (T2DM). It is unknown whether muscle free fatty acid (FFA) availability or intramyocellular fatty acid trafficking is responsible for the abnormal response to insulin. Likewise, the investigators do not understand to what extent the incorporation of FFA into ceramides or diacylglycerols (DG) affect insulin signaling and muscle glucose uptake. The investigators will measure muscle FFA storage into intramyocellular triglyceride, intramyocellular fatty acid trafficking, activation of the insulin signaling pathway and glucose disposal rates under both saline control (high overnight FFA) and after an overnight infusion of intravenous niacin (lower/normal FFA) to provide the first integrated examination of the interaction between FFA and muscle insulin action from the whole body to the cellular/molecular level. By identifying which steps in the insulin signaling pathway are most affected, the investigators will determine the site-specific effect of ceramides and/or DG on different degrees of insulin resistance. Hypothesis 1: Greater trafficking of plasma FFA into intramyocellular DG will impair proximal insulin signaling and reduce muscle glucose uptake. Hypothesis 2: Lowering FFA in UBO and T2DM by using an intravenous infusion of niacin will alter trafficking of plasma FFA into intramyocellular ceramides in a way that will improve insulin signaling and increase muscle glucose uptake. Hypothesis 3: Lowering FFA in UBO and T2DM by using an intravenous infusion of niacin will alter trafficking of plasma FFA into intramyocellular DG in a way that will improve insulin signaling and increase muscle glucose uptake.

Time Restricted Eating As Treatment (TREAT) for Diabetes Mellitus: A Pre-Post 12 Week Study on the Effectiveness of Intermittent Fasting in Asians With Type 2 Diabetes Mellitus

Type 2 Diabetes Mellitus (DM) is a silent epidemic that affects 11.3% of Singaporeans. It has numerous clinical sequelae including macrovascular and microvascular disease. Nutritional therapy has been widely accepted as being safe and affordable as compared to pharmacotherapy. It is estimated that current nutritional therapy is able to reduce HbA1c levels by 1 to 2 percent under ideal circumstances. A weight loss of >5% is needed to have any significant beneficial effects on the levels of HbA1c, lipids, and blood pressure. This requires extensive modification of lifestyle, calorie restriction, regular exercise, and close supervision by health care professionals; impracticable for most patients. Intermittent Fasting that has been shown to be effective in improving the metabolic state of human subjects. The investigators ask if a simpler dietary regime based on time restricted eating would produce the necessary weight loss and good metabolic outcome. In this pilot single arm pre-post study, 50 adult diabetic patients will be educated on Time Restricted Eating As Treatment (TREAT). Under this intervention, subjects will skip one meal a day and aim for a fasting period 16 hours a day. In the 8 hours where eating is permitted, subjects are encouraged to eat normally based on what is recommended for diabetic patients in usual care. Relevant clinical parameters, such as blood glucose control, lipid and triglyceride levels and anthropometry will be monitored over a 12-week period. This study would have major clinical impact if it is found that TREAT can result in the improvement of cardiometabolic parameters and is practicable and sustainable in a real world setting.
