Active clinical trials for "Diabetes Mellitus, Type 2"

The aim The aim of the present study is: The metabolic risk factors that can predict diabetes after 10 years in a Circassians population-based sample of people who were aged 35 years or older and living in Israel. To define the incidence of type 2 diabetes mellitus in Circassians minority in Israel. The hypothesis of the study: High fasting glucose has the most powerful predictive value for type 2 diabetes mellitus in the future. The claimed importance of the study: Finding a powerful risk factor for future diabetes mellitus can contribute to intensifying the preventive measures in a small part of the population, by that to reduce the incidence of new diabetes without increasing the health cost.

To study the effects of pioglitazone on the steroidogenic enzyme axis in eugonadal men with type 2 diabetes mellitus.

Cardiovascular events are the most common cause for death in type 2 diabetes mellitus (T2DM) patients. Male diabetics have a 2 to 3 fold risk for cardiovascular disease (CVD) whereas female diabetes patients have a 3 to 7 fold risk for suffering from a CVD. Endothelial dysfunction (ED) plays a central role in the development of atherosclerotic lesions. Moreover, ED represents an important diagnostic and prognostic parameter to estimate the cardiovascular risk in an early state. Experimental and clinical studies indicate that T2DM is closely associated with ED, which may be the consequence of a reduced bioactivity of nitric oxide (NO). The success of diabetes therapy is monitored by the long-term parameter HbA1c. However, only two thirds of all patients with T2DM in the USA and Europe find themselves in the recommended HbA1c span (6.5-7.0 %). Consequently, oral anti-diabetic medication needs permanent adjustment and intensification in order to delaying the progress of T2DM. Recently, two peptide hormones with insulinotropic effects were identified. These hormones, glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), are secreted by the gastrointestinal tract after exposure to glucose in nutrition. Physiological effects are increased insulin secretion, inhibition of glucagon secretion and reduction of body weight. Furthermore, these incretins are reduced in patients with impaired glucose tolerance. Thus, the therapeutic approach lies within the elevation of GLP-1 and GIP by preventing their degradation through the enzyme DPP-4 (dipeptidylpeptidase 4). Thereby, the so-called gliptins inhibit the DPP-4 enzymes. Best results in HbA1c reduction were achieved when gliptins were combined with metformin, glimepiride or pioglitazone. In this study, patients with T2DM, who are taking metformin as first line medication but do not achieve a HbA1c below 7.0 %, will routinely get an add-on therapy with gliptins (Vildagliptin or Sitagliptin) as second line therapy according to the guidelines of the Österreichische Diabetes Gesellschaft (ÖDG) prescribed by a medical doctor not involved in this study. This medication is a ÖDG standard therapy in T2DM, which patients receive anyway despite this study. Therefore, the therapy with gliptins is not a study medication and is not influenced by the study either. Only patients, who will meet the inclusion criteria of the study and voluntarily participate in the study, will be investigated.

Consumption of a low glycemic index (GI) diet has been shown to improve glycaemic control in type 2 diabetics(Brand-Miller et al., 2003; Jenkins et al., 2008). In addition to the benefits for glycaemic control there is some evidence for acute improvements in cognitive performance after consumption of low GI foods compared with high GI foods in both adults (Benton et al., 2003; Kaplan et al., 2000) and adolescents (Ingwersen et al., 2007; Smith and Foster, 2008). Given these findings it is possible that low GI focused dietary interventions designed to improve glycaemic control and health outcomes for diabetic patients could also improve the cognitive function of these patients. This is of particular relevance in light of the evidence associating type 2 diabetes with cognitive decrements (Awad et al., 2004; Stewart and Loilitsa 1999; van Harten et al., 2006). To date two studies with type 2 diabetics have reported that a low GI breakfast was associated with increased verbal memory performance compared to a high GI breakfast (Greenwood et al., 2003; Papanikolaou et al. 2006). Further research should investigate the benefit of low GI foods to cognition. The aim of this study is to examine the effects of high and low glycaemic index breakfast on cognitive performance in adults with type 2 diabetes. Participants will perform a battery of cognitive tests after consuming 3 different breakfasts (high GI, low GI, and water) on 3 different tests days. The participants will be recruited from the general public and from the Leeds Teaching Hospital diabetes clinic. This research can benefit the development of specific dietary behaviours aimed at reducing diabetes related cognitive decline. This research is part of a PhD funded by the Economic and Social Research Council and the University of Leeds.

The purpose of this study is to replicate the positive impact observed in IRB #1050955, but conduct this over a shorter period to potentially maximize patient outcomes and make care more affordable. Intermountain intends to build a diabetes program with CGM based on the findings. Senior stakeholders, clinicians and operators are aligned on this vision including the Community Based Care triad, Executive Leadership Team, and our Diabetes Prevention Program.

Multicentric, observational, cross-sectional study in Italy. The aims are to evaluate the daily metformin prescribed dose and the impact of renal function and concomitant medication in diabetic patients over 65 years.

All across surgery specialties, wound or implant infections constitute rare, yet potentially severe complications of surgical procedure. It is considered, that glucose metabolism disorders, e.g. diabetes, are one of the main risk factors of such condition. Aim of the study The aim of the study is a prospective evaluation of glucose blood level and its variability during 2 weeks before hospitalization and 2 weeks of postoperative period in patients, that will undergo elective orthopaedic surgeries, and its impact on number of cardiovascular and orthopaedic complications. Materials and methods To this study, patients qualified for elective total knee or hip replacement in the single orthopedic center will be recruited. 100 patients will be included in this study. Every patient will be evaluated on the risk of developing diabetes mellitus in 10 years time and on the risk of death in 10 years due to the cardiovascular events. 14 days before procedure patients will have continuous glucose level measurement sensor implemented in subcutaneous tissue. After 14 days, during standard visit for stitches removal, the sensor will be removed and glycemia data will be collected. Next, patients will have their casual glucose blood level checked and surgery outcome, cardiovascular events or surgery complication risk evaluated in 3-, 6- and 12 month follow-up visits. Expected benefits of the study Results of this study may allow to define impact of orthopaedic treatment on glycemia and possible necessity to modify treatment of hyperglycemia in perioperative period in patients with Diabetes Mellitus type 2 (DM2). Moreover it will allow to specify change of glucose levels and possibly implicating a need to monitor perioperative glycemia in patients without carbohydrate metabolism disorders. Additionally, the study will help to evaluate corelation between perioperative glucose blood level and the risk of cardiovascular events or surgical complications in 1-year after the procedure, which may decrease the risk of such incidents in the future (e.g. by adequate control and effective treatment of hyperglycemia), hence may result in reduction of mortality and lesser lowering of the quality of life in patients with DM2 or high risk of it.

The study will assess the serum expression of MMP-9 in normal people, type 2 diabetic patients and type 2 diabetic patients with atherosclerosis.

Short-term intensive insulin therapy (SIIT) is able to reverse β cell dysfunction and induce glycemic remission in patients with newly diagnosed type 2 diabetes. On the other hand, intensive control of glucose and lifestyle modification are two key elements in preventing chronic complications, especially microvascular neuropathy. However, no study reported the long-term effect of SIIT on the chronic complications. In this multi-center, case-control study, effects of SIIT on the proportion of long-term chronic complications as well as potential biomarkers were investigated. In total, 777 patients with type 2 diabetes, including 259 patients who participated SIIT when diabetes was newly diagnosed and 518 patients who received routine diabetic therapy will be enrolled in 12 centers in China. After baseline assessments, all patients will undergo complications assessment, including records of cardiovascular diseases (CVD), carotid ultrasonography, electrocardiogram, echocardiography, fundus photography, urinary albumin excretion, Toronto Clinical Neuropathy Scale and Composite Autonomic Symptom Score. Primary endpoint is the difference in the proportions of macrovascular and microvascular complications between groups. Secondary endpoints include the difference of glucose control, insulin resistance, complexity of anti-diabetic therapy and self-management skills and quality of life between two groups. What's more, new biomarkers, which may indicate the occurrence of chronic complications of diabetes, such as circulating endothelial progenitor, β cell dysfunction, and T cells.
