Active clinical trials for "Diabetes Mellitus, Type 1"

The purpose of this research study is to test how different levels of insulin block the effect of glucagon. Insulin is a hormone that lowers blood glucose. Glucagon raises blood glucose. Both are natural hormones made by people without diabetes. Sensor-based blood glucose control studies have been done by our research group using glucagon in small doses to prevent hypoglycemia (low blood sugar). However, sometimes glucagon does not work to raise blood sugar. The investigators believe this is because of too much insulin in the body. This study will help determine how different levels of insulin in the body affect the ability of glucagon to raise blood sugar.

A randomized controlled study to evaluate the effect of 3 months use with interactive computer game- "My Diabetic Friend"- comparing to conventional diabetes education on metabolic control, quality of life and diabetes knowledge.Patients will be randomized into two groups- one group will be supplied with interactive computer game, "My Diabetic friend", installed on a computer designed for children's educational needs for a period of three months and the other group will be supplied with the same computer without the interactive computer game for three months. Metabolic control, quality of life and diabetes knowledge will be evaluated before and after the use of the computer. The trial is consisting of two main periods: 3 months of the main study period and an optional extension period consisting of the following 3 months : The study will include two main periods; Period 1 which will last 3 months, in a randomized controlled manner, this period will serve as the main study period to assess the primary and secondary endpoints of the study. Period 2: this extension period will not be an integral part of the study, and only patients who are willing will take part at this period, will continue to participate at the optional extension period. During the extension period, patients in the intervention group will be offered to continue the use of the Computer game -"My diabetic friend) for the following 3 months, and patients who participated at the control group during period 1, will be offered to start to use the Computer Game - "My Diabetic Friend" for the following 3 months.

Glutathione is normally present at high levels in the blood and plays an important role in the body's defense against oxidative stress, that is, against the damage caused to the body by several reactive oxygen species produced by the metabolism of most nutrients, including glucose. Glutathione is a small peptide made from 3 amino acids, glutamate, cysteine, and glycine. This study is looking at how blood sugar levels may affect the way glutathione is made and used by the body. Since glutathione is continuously synthesized and broken down, the amount of glutathione present in the blood depends on the balance between its rate of synthesis and its rate of use. In earlier studies, we found that in poorly controlled diabetic teenagers, glutathione was low, not because it was not produced fast enough, but because it was used at an excessive rate. In this study, we want to find out whether improving blood sugar control will increase glutathione levels, and, if so, how long this will take. We also hope to find out if oral supplementation with a mixture of several antioxidant vitamins and minerals will increase glutathione levels more than taking a placebo.

Study hypothesis: Waking up in response to an alarm clock may evoke a stress reaction that leads to rising glucose concentrations. The purpose of this study was to prove this hypothesis with continuous glucose monitoring over three nights. Night (a) with an alarm clock set at 2 h intervals for glucose self monitoring, Night (b) with a nurse performing blood glucose determinations, and Night (c) with the patients left undisturbed.

The study seeks to use microdialysis and microperfusion techniques to assess the feasibility of performing insulin delivery and glucose sensing at a single subcutaneous tissue site.

The study seeks to use microdialysis and microperfusion techniques to assess the feasibility of combining insulin delivery and glucose sensing at a single subcutaneous tissue site.

Randomized, two arms, controlled, open study comprised of two consecutive segments. At the first segment that will last during the first 4 months of the study, patients will be randomized to the Care link treated group or non Care link treated group. At this segment of the study the usage of the Care link system will be accompanied by the diabetic team, through at least monthly contact via the Internet initiated by the diabetic team. At the second segment of the study, during the following 4 months, both groups will use the Care link System, home-use, without support initiated by the diabetic team.

The investigators hypothesize that subcutaneous pramlintide as an adjunct to mealtime insulin immediately prior to meals can significantly reduce post-prandial glucose concentrations compared with mealtime insulin alone in children with type 1 diabetes. This is a 36 day, randomized, two-arm, open-label study with a treatment arm (taking pramlintide before all meals) and a control arm (diabetes regimen as usual).

Background: Post-prandial hyperglycemia is common in people with type 1 diabetes. Objective: The aim was to determine the impact of low vs high glycemic index (GI) on post-prandial glycemia for breakfast vs lunch and to quantify these effects with continuous glucose monitoring. Design: Seven adult subjects with type 1 diabetes participated in two experiments, each consisting of two meals each. In one experiment, both meals had a low GI; in the other, high GI. Meals were given 195 minutes apart and were matched for carbohydrate, protein, and fat content. Each subject received his usual pre-prandial insulin dosage, followed by a continuous subcutaneous basal insulin infusion for the remainder of the experiment. Arterialized venous glucose was analyzed every 15 minutes and sensor glucose was recorded every 5 minutes.

Vision loss from diabetes is often preventable with timely detection and treatment. Patients with diabetes may not understand the importance of annual dilated eye examinations or recognize the benefits of early detection of diabetic eye disease. The proposed research project compares usual eye care to eye care emphasizing patient education for adult patients with diabetes.
