Active clinical trials for "Diabetes Mellitus, Type 1"

This study aims to investigate the effect of health belief model-based mobile online training applied to patients with diabetes on insulin therapy.

The goal of this study is to examine the effect of chronic and acute hyperglycemia in type 1 diabetes mellitus (T1DM) on brain glutamate levels using magnetic resonance spectroscopy (MRS), and associations of brain glutamate with symptoms of depression.

In a randomized, cross-over designed study, the investigators examined the effectiveness of the carbohydrate counting method after consumption of mixed meals typical of the Greek cuisine with various protein and fat contents in a sample of people with type 1 diabetes (DM1). The investigators also tried to further explore the effects of additional extra virgin olive oil (11 ml) on the glycemic response.

Brown adipose tissue has the capacity to consume large amounts of energy and has insulin-independent glucose uptake. The investigators have recently observed an inverse correlation between irisin levels and insulin needs of type 1 diabetes patients. Transplantation of brown adipose tissue to insulin-deficient rats normalized their blood glucose levels. In this study 12 patients with long-standing type 1 diabetes (>10 years) and with variable exogenous insulin needs will be investigated for amount of brown adipose tissue with positron emission tomography using the tracer 18F-deoxy glucose.

Anxiety about needles is a commonly expressed concern by diabetics about beginning insulin therapy. A shorter, thinner pen needle that delivers insulin with the safety and efficacy profile of currently marketed pen needles may appeal to many diabetic patients as the new needle may be perceived as less intimidating and more comfortable. Currently marketed pen needles range in length from 5 to 12.7 millimeters (mm). The primary purpose of this study was to evaluate whether the investigational 4mm x 32 Gauge(G) pen needle manufactured by Becton, Dickinson and Company (BD) provides equivalent glucose control (as measured by fructosamine levels) as the currently marketed BD 5mm x 31 G and BD 8mm x 31 G pen needles (PN)in diabetic subjects with varying insulin dosage regimens.

Anxiety about needles is a concern commonly expressed by diabetics when beginning insulin therapy. A shorter, thinner pen needle that delivers insulin with the safety and efficacy profile of longer pen needles may appeal to many diabetic patients as the shorter needle may be perceived as less intimidating and more comfortable. While pen needles of 4 to 8 mm in length are generally used for insulin injection in patients considered thin or normal weight, longer (12.7 mm) needles are still often prescribed for overweight or obese patients with diabetes. Since skin thickness is nearly constant across a range of body mass index (BMI), a clear rationale exists for the use of shorter needles in obese patients. (Gibney et al., CMRO 2010) The primary purpose of this study is to evaluate whether the BD Ultra-Fine™ Nano 4mm x 32 Gauge(G) pen needle manufactured by Becton, Dickinson and Company (BD) provides equivalent glucose control (as measured by hemoglobin A1c levels) as the BD Ultra-Fine™ 8mm x 31G and the BD Ultra-Fine™ 12.7mm x 29G pen needles in obese subjects with diabetes.

Specific Aim: To establish the feasibility of studying the change in endothelial function caused by induced moderate hyperbilirubinemia in type 1 diabetes. Atazanavir, a drug that inhibits bilirubin conjugation, will be used to induce moderate hyperbilirubinemia. Endothelial function will be measured before and after atazanavir therapy. In addition, plasma markers of antioxidant capacity and oxidant stress will be measured as proof-of-concept that induced moderate hyperbilirubinemia has favorable effects on oxidative stress in type 1 diabetes.

Elevations of plasma cortisol, a stress hormone, during prior episodes of low blood sugar (hypoglycemia) appear to be responsible for the deficient responses during subsequent hypoglycemia. Our specific aim is to determine if dehydroepiandrosterone (DHEA), a hormone with anti-corticosteroid actions, can prevent hypoglycemia associated autonomic failure in type 1 diabetic volunteers.

Insulin lispro is approved by the Food and Drug Administration (FDA) for the treatment of diabetes mellitus. Recombinant human hyaluronidase (rHuPH20) is approved by the FDA as an aid to the absorption and dispersion of other injectable drugs. In this study, rHuPH20 combined with a non-preserved (NP) formulation of regular human insulin (INSULIN-PH20 NP) will be compared to insulin lispro with respect to absorption and action of insulin.

The aim of this trial is to demonstrate bioequivalence of Glaritus® to Lantus® with regard to its total and to its maximum serum insulin concentrations.
