Signaling Mechanisms and Vascular Function in Patients With Diabetes Mellitus
Type 1 Diabetes MellitusType 2 Diabetes MellitusThe purpose of the study is to learn how blood vessel function is altered by diabetes. We are studying an investigational drug, Ebselen, to see if it can improve the ability of blood vessels to relax (widen).
The Effect of Gastric Bypass Surgery on the Glucose Metabolism Seen in Patients With Type 2 Diabetes...
Type 2 DiabetesGastric bypass surgery has in many studies shown total remission of type 2 diabetes as early as 1 - 2 days after surgery and this is before any real weight loss has occurred. This suggest that the remission of the diabetes is due to the direct effect of the operation more that the secondary effect of the weight loss. The reason for the major effect on the glucose metabolism after gastric bypass surgery is still unaccounted for. This PhD. project will try to unveil some of the mechanisms that could explain the effect of gastric bypass surgery on the glucose metabolism seen in patients with type 2 diabetes. The hypothesis of the study is that a factor "X" will course the remission of the diabetes. This factor "X" is related to the anatomic changes of the gastro intestinal tract, by eliminating the foods passage through the distal part of the ventricle and the duodenum, in combination with the Roux- en-Y sling. The PhD. project will consist of clinical trails on patients that will undergo gastric bypass surgery. The studies will take place before and within the 1. week after surgery. The investigators will measure different hormones and adipokines in fast and the postprandial state. To discover possible new proteins the investigators will run proteomic on some samples. All the results will be compared to the same parameter on patients undergoing gastric banding, where the anatomy of the intestine hasn't been changed.
Incretin Effect in Lean and Obese Subjects
Incretin EffectInsulin Resistance1 moreThe incretin effect is markedly reduced in patients with type 2 diabetes. Data support the notion that this deficiency is a consequence of the diabetic state. However, the impact of insulin resistance on the incretin effect in obese individuals who uphold a normal glucose tolerance (NGT) despite their insulin resistant state remains to be elucidated. The primary aim of the present study is to evaluate the separate impact of one of the cornerstones of type 2 diabetic pathophysiology, namely insulin resistance, on the incretin effect in lean and obese patients with type 2 diabetes and in two matched normal-glucose tolerant groups of healthy control subjects.

Type 2 Diabetes MellitusThe aim of this study was to evaluate the correlation between 1,5-Anhydroglucitol in patients with HbA1C <7%, and glycemic excursions as assessed by the continuous glucose monitoring system compared to fructosamine.
Fracture Risk With Thiazolidinediones
FracturesBone1 moreTreatment with thiazolidinediones (TZD) has recently been reported to possibly increase the risk of fractures in a randomized trial exploring the efficacy of rosiglitazone (RSG), metformin, or glyburide encompassing 4360 patients with type 2 diabetes. It is hypothesized that spironolactone, a diuretic that is broadly used for the treatment of fluid retention and edema associated with TZD, has a potential protective effect against bone fractures. However, to our knowledge, this has not been tested in diabetic patients treated with TZD. Amiloride is another diuretic that shares with spironolactone the anti mineralocorticoid ion gated channels activity and will be analysed in this study with regard to possible protective effect against bone fracture in combination with TZD. This study is a nested case-control study conducted among type 2 diabetes subjects exposed to TZD. The study aims to explore if the risk of fracture is reduced among type 2 diabetic subjects exposed to spironolactone and TZD. The study will compare the odds of any low impact fracture, and hand, foot, upper arm, wrist, and hip fracture incidence in subjects treated with TZD+spironolactone and TZD+amiloride compared to subjects treated with TZD only. The study population will consist of type 2 diabetes patients aged 18 -65 years old exposed to TZD. To be eligible for the study, a subject must have had at least one International Classification of Disease (ICD)-9 code for type 2 diabetes and have at least 6 months or at least 12 months of exposure to TZD (rosiglitazone [RSG], pioglitazone [PIO] or troglitazone) during their follow-up time available in the database.

Action in Diabetes and Vascular Disease Preterax and Diamicron MR Controlled Evaluation Post Trial...
Diabetes MellitusType 2The study is designed to determine the long term, post trial effects of the two interventions studied in ADVANCE (routine blood pressure lowering with perindopril-indapamide as compared with placebo and intensive gliclazide-MR based glucose control as compared to standard guideline based glucose control) in individuals with type 2 diabetes at high risk of cardiovascular events. The long term, post randomization effects of the two study interventions will be investigated separately as they were for the main trial. This study will clarify and quantify the long-term, post trial (often referred to as legacy) effects of these two interventions in a broader population of patients with type 2 diabetes from high and low to middle income countries, and in the setting of comprehensive cardiovascular risk factor treatment. With the ADVANCE trial infrastructure and surveillance system already in place, the implementation of extended follow-up will be feasible. The conclusions of this follow up study will have profound clinical implications for the care of patients with type 2 diabetes around the world.
