GIP, GLP-1 and GLP-2 in Type 2 Diabetic Hyperglucagonemia
Type 2 Diabetes MellitusIn order to investigate the mechanisms underlying the hyperglucagonemia characterizing patients with type 2 diabetes mellitus (T2DM) we wish to test the following hypothesis: Do pancreatic alpha-cells exhibit inappropriate glucagon responses to substances released from the small intestine (GIP, GLP-2 and GLP-2) in patients with T2DM?
An Observational Study of Type 2 Diabetes in Patients Starting on NovoMix® 30 Treatment
DiabetesDiabetes Mellitus1 moreThis study is conducted in Europe. The aim of this observational study is to evaluate the incidence of serious adverse drug reactions when initiating or switching to insulin therapy with NovoMix® 30 in subjects with type 2 diabetes under normal clinical practice conditions
Does Bone Structure Explain the Increased Fracture Risk in Type II Diabetes Patients? A Pilot Study...
OsteoporosisFor this cross-sectional case control pilot study 30 women, 55-75 years old with type II diabetes will be recruited. Diabetes will be defined as self-report of diabetes previously diagnosed by a physician, use of hypoglycemic medications, or fasting glucose > 126 mg/dl (7.0mM) in accordance with the American Diabetes Association criteria. The diabetic patient population will be divided into 2 groups: patients with status post low energy fractures of the proximal humerus, the proximal femur, the ankle and the foot (n=10) versus diabetic patients with no fractures or low energy trauma fracture history (n=10). An additional group of 10 diabetic postmenopausal women will be recruited and will have magnetic resonance imaging (MRI) of the lower back only. Caucasian, Asian and Hispanic women will be combined since a previous study suggested that BMD is very similar in these 3 population and that ethnic differences are minimal. In addition a population of 10 age-matched, BMI-matched, race-matched healthy women, without osteoporotic fractures will be examined. In all of these volunteers a medical history will be obtained to ensure good health status and rule out chronic diseases that would have an impact on bone metabolism. Patients will undergo MRI, QCT and high-resolution peripheral quantitative computed tomography (HR-pQCT) examinations to determine bone mineral density and bone structure/quality. The hypothesis of this pilot project is that type II diabetic patients with and without low-energy fractures have a different trabecular bone architecture and composition, which is also different when compared to normal age-matched healthy patients. Architectural differences in these three patient groups may be visualized with high resolution MRI and high-resolution peripheral quantitative computed tomography (HR-pQCT) and will be most pronounced at the calcaneus and the distal tibia. Analyzing structure parameters obtained from high resolution MRI and spectroscopy may improve our understanding of the pathophysiology of diabetic bone disease and the prediction of fracture risk in an elderly diabetic population.

Study of Renal Blood Flow During Human Endotoxemia
HealthyType 2 Diabetes1 moreThe purpose of the present protocol is to study whether endotoxemia will affect the renal blood flow in type 2 diabetics and healthy volunteers.
Evaluation of SCOUT DS in Subjects With Type 2 Diabetes #2
Diabetes MellitusNon-Insulin DependentThe primary objective of the trial is to collect SCOUT DS and Hemoglobin A1c measurements of subjects who have been diagnosed with Type 2 diabetes.
Study of the Relationship Between Blood Vessels and Insulin Response in Adolescents
Diabetes MellitusType 23 moreThis study is designed to determine whether there is a relationship between the way insulin and blood vessels work. The difference in the interaction between Caucasian and African American adolescents will also be examined. This may play a role in the differing rates of heart disease and diabetes between the two groups.
Long-term Mortality in Diabetics Undergoing Major Surgery
Diabetes MellitusCoronary Heart Disease1 morePatients with CAD and diabetes mellitus have a better prognosis than patients with CAD and no diabetes mellitus. In acute coronary syndrome patients with an insulin therapy had a better survival than patients with oral antidiabetics. But there is not known wether perioperative therapy with insulin or oral antidiabetics is associated with higher risk for higher perioperative cardiac morbidity and mortality and worse long-term survival.
Fatty Acid Binding Protein 2 (FABP2) Ancillary Proposal
Type 2 Diabetes MellitusTITLE: CSP 465-C, Fatty Acid Binding protein 2 (FABP2) ancillary proposal to CSP# 465 Glycemic Control and Complications in Diabetes Mellitus Type 2. Angeliki Georgopoulos, M.D. Carlos Abraira M.D. William Duckworth M.D. Fatty acid binding protein 2 (FABP2) is involved in the transport of long chain fatty acids across the intestinal epithelium. A common (40-45%) polymorphism of FABP2 gene (codon 54 Threonine for Alanine) results in increased intestinal fatty acid absorption and triglyceride secretion (Baier et al J Clin Invest 95:1281-87, 1995; Baier et al J Biol Chem 271: 10892-10896,1996). We have found (JCEM 85:3155-60, 2000) that in patients with type 2 diabetes, the codon 54 polymorphism of the FABP2 results in fasting and postprandial hypertriglyceridemia. Since hypertriglyceridemia is a risk factor for atherosclerosis in type 2 diabetes and it is part of the insulin resistance syndrome, the objective of this ancillary study would be to screen the participants of the CSP# 465 study for the polymorphism and assess a) whether those carrying the polymorphism respond differently to the various treatment modalities and b) whether they develop more cardiovascular events compared to the ones lacking the polymorphism. There is one study that suggests an association of the polymorphism with a history of parental stroke (JCEM 85:2801-4, 2000). The only additional request from the study participants will be to agree to the collection of a blood sample to be used for DNA isolation and screening for the polymorphism. No additional funds are requested. If this polymorphism proves to be a predictor of either the response to a specific treatment modality or of the risk to macro-vascular complications, it will be very easy to screen for it and target our treatment modalities appropriately.
Change of Lifestyle by Persons in Risk of Type 2 Diabetes
Type 2 DiabetesWe know that changing lifestyle can prevent type 2 diabetes. The challenge is how to help people changing their lifestyle. We have people in 2 groups: half of them is meeting in grops of 10 persons (interventiongroup), the other ones are just visiting their doctor (controlgroup).
