Active clinical trials for "Diabetes Mellitus, Type 2"

Impaired uptake of glucose by skeletal muscle is a key feature of type 2 diabetes mellitus. It is unclear to what extent impaired insulin uptake from capillaries into skeletal muscle interstitium plays a role in this process. We hypothesize that impaired uptake of insulin from capillaries into skeletal muscle interstitium is involved in impaired glucose uptake by skeletal muscle in type 2 diabetes mellitus.

"The goal of this work is to critically test the hypothesis that there exists a different profile of bile acids (BAs) in patient with type 2 diabetes mellitus (T2DM) compared with normal controls. Through confirmation of different profile of BAs in T2DM, investigator will suggest modulation of specific bile acids as a new possible treatment target in patients with T2DM. Investigator also expect the specific BAs signature will be used to screen T2DM before hyperglycemia. In addition, investigator will evaluate the association between each BA species and serum total glucagon like peptide-1 (GLP-1) or fibroblast growth factor-19 (FGF-19) concentrations to determine if the specific BAs profile is related with total GLP-1 or FGF-19 concentration in serum. Investigatr also evaluates the correlation between each BA species and metabolic profiles and oxidative stress marker to find possible roles of each BA component in glucose metabolism.

Objective: The main target of this study was to research the early changes of retrobulbar and intrarenal hemodynamics, then to research the correlation between them in type 2 diabetes (T2DM) patients without diabetic kidney disease (DKD) and diabetic retinopathy (DR). Method: 35 T2DM patients (diabetes group) without vascular complications and 30 healthy people (control group) were recruited to research the early changes of renal function, retrobulbar and intrarenal hemodynamics, and then to research the correlation between them. The primary endpoints were the intrarenal hemodynamic (bilateral kidney RI) in bilateral interlobular renal arteries were evaluated using Doppler Sonographic; the secondary endpoints were the retrobulbar hemodynamics RI in the bilateral central retinal artery (CRA), posterior ciliary artery (PCA), and arteria ophthalmica (OA) were evaluated using color doppler imaging (CDI); the tertiary endpoints were the biochemical endpoints: blood-fat (TC, HDL-C, LDL-C, and TG), FPG, 2hPG, HbA1c, and renal function parameters (BUN, Cr, and GFR); in addition, the albumin excrete rate (AER), urinary albumin/creatinine ratio (UACR) were measured.

Inadequate suppression of intramuscular and adipose tissue lipolysis, and consequent excessive delivery of fatty acids to ectopic tissues (e.g. muscle, pancreas and liver) could play an important role in the development and exacerbating of insulin resistance. Therefore, the investigators propose to study the regulation of adipose tissue and skeletal muscle lipolysis, as well as further characterize the intracellular lipolytic pathways within these tissues, in obese normoglycaemic versus long-term diagnosed type 2 diabetic subjects.

The primary objective of the trial is to collect SCOUT DS, random capillary glucose and Hemoglobin A1c measurements from subject 18 years of age or older.

Medic Mobile conceptualized and proposed the creation of an SMS-based appointment validation tool to automate appointment confirmation and rescheduling. Working in parallel with the San Mateo Medical Center (SMMC) electronic medical records (EMR) system, the software tool will automate reminders that request text responses from patients to either confirm or request to reschedule their upcoming appointments. While simple in concept, this tool aims to free up scarce clinical resources which are currently allocated to daily patient phone call reminders. With funding from a Bay Area foundation, the investigators will develop and pilot this open-source software tool in a 12-month randomized-controlled trial, slated to begin in October 2012. The endpoints of the study will aim to demonstrate improvements in both appointment adherence and glycemic control.

The purpose of this study is to validate a predictive model of diabetic retinopathy progression in patients with diabetes mellitus type 2 patients to clinically significant macular edema (CSME) needing treatment either photocoagulation or intravitreal injections (ITV) using non-invasive techniques.

Type 2 diabetes is the predominant type of diabetes. Because a quiet evolution, it is difficult to have a rapid diagnose. A better knowledge about pathophysiological mechanisms at the origin of type 2 diabetes and about its complications could make it possible to improve the prevention and the treatment of this disease. Research team developped a new research axis : the microbiota of the intestinal mucosa. They proved a translocation process of intestinal bacteria from the intestinal mucosa to different tissue of the organism implicated in glucose homeostasis. This mechanism is involved in the type 2 diabetes development. A clinical study (MICIMAB) of predictive biomarkers of diabetes and obesity is ongoing. In parallel, the same team explored the role of intestinal immunity modifications in the bacteria translocation from the gut to the blood circulation. They already have some results on animal model but not yet in human. In animal model, a solid reduction of lymphocytes T CD4 Th17 in the intestinal wall is responsable of the translocation of intestinal bacteria and in the induction of a metabolic inflammation wich promotes insulin resistance, abdominal obesity development and type 2 diabetes. The aim of this study is to explore this hypothesis in human to have therapeutic solution later.

The main aim of this study is to compare 2 different measurements of visceral fat that can be easily used in clinical practice (waist circumference versus bioelectric impedance) in relation to known risk factors of coronary artery disease in a large cohort of patients with type 2 diabetes and with a BMI range between 20-45 kg/m2

The main objective of the study is to follow prospectively a cohort of patients with pre-diabetes to understand the pathophysiological mechanisms involved in switching from pre-diabetes to type 2 diabetes and to identify new biomarkers of type 2 diabetes risk in this population.
