Active clinical trials for "Diabetes Mellitus"

This is a pilot study to enroll 100 people to assess the incidence of lipohypertrophy as detected with ultrasound and its impact on glycemic variability.

It is well established that CD8 and CD4 T cells reactive against defined islet antigens are associated with initiation and progression of Type 1 Diabetes (T1D). In previous work, we have demonstrated that it is possible to redirect T cells against pathogenic T cells via chimeric peptide/MHC/CD3-zeta receptors in a peptide-specific manner and to prevent, or inhibit diabetes in NOD mice. In this study we intend to extend this approach to T cells of T1D patients. Working hypothesis: Beta cell-reactive CD8 T cells of human T1D patients can be immuno-targeted by their own gene-modified cytotoxic T lymphocytes (CTLs). Aims: Our major aim is to demonstrate, in a set of ex-vivo experiments, such immunotargeting with T cells derived from T1D patients at the Ziv Medical Center. To this end we will stimulate and expand autoreactive CD8 cells in blood samples of T1D patients and target them, ex-vivo, with genetically-reprogrammed CTLs which are present in the same blood samples.

Patients with type 1 diabetes type 1 (DM1) have increased risk of death due to heart disease and stroke. These cardiovascular conditions (CVD) are the leading cause of death in patients with DM1 younger than 40 years of age and up to 35% of all persons with DM1 will die before age 55 from CVD. Strategies are needed to help identify adolescents with DM1 at risk for CVD so that interventions to prevent heart disease and stroke can be undertaken.

This study is designed to compare the serum sphingolipidomic analyses in healthy, pre-diabetic and diabetic subjects. age, sex and BMI are matched among these three groups. As ceramide, sphingosine, sphingosine-1-phosphate and sphinganine are involved in inflammation, immunity and cancer, investigators proposed a hypothesis that sphingosine-1-phosphate and other sphingolipids may be associated with the progress of type 2 diabetes. sphingolipids may be a biomarker for diabetes.

The primary objective is to identify compare SCOUT DS to random capillary glucose for identification of at-risk subjects with dysglycemia defined by hemoglobin A1c ≥ 6.0%.

Retinal function is highly dependent on the glucose supply. Thus, functional adaptations occur in response to both acute and long-term changes in glycaemia. The purpose of this study is to examine functional and metabolic aspects of retinal adaptation to long-lasting changes in glycaemic control in patients with diabetes. The adaptational phenomena will be characterized by electroretinography, dark adaptation, measures of retinal perfusion and oximetry as well as diabetic retinopathy grading and (OCT).

The study aim is to establish a consecutive population of newly referred type 2 diabetes mellitus patients and among these to describe the degree of macrovascular disease by evaluating left ventricular systolic and diastolic function (echocardiography), myocardial perfusion (single-photon emission computed tomography (SPECT)), the peripheral vascular perfusion (strain gauge toe blood pressure measurements and a ultrasound scan of the a. carotis communis). Further, the degree of microvascular disease will be evaluated (glomerular filtration rate assessment, fundus photography and biotesiometry). Finally the cohort will be followed the next two years to assess the prognostic value of the above-mentioned parameters
