Filter by:A single arm, single treatment study is proposed to assess the feasibility of a portable artificial pancreas system outside of a hospital based clinical research center. Adult T1DM patients will use a newly developed platform in conjunction with a subcutaneous insulin infusion pump and a continuous glucose monitor for 18 hours is quasi free conditions (hotel).
Open-label, randomized, forced-titration clinical trial evaluating the efficacy and safety of TI Inhalation Power in combination with a basal insulin versus insulin aspart in combination with a basal insulin
The main study objective is to compare real-time continuous subcutaneous glucose monitoring (CGM) combined with overnight automated closed-loop glucose control, and real-time CGM alone in the home setting.
This protocol will investigate physiological parameters including insulin sensitivity and counterregulatory function using a mixed meal test and induced hypoglycemia in subjects with type I 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.
The investigators are conducting this study to find out whether a new device can control blood sugar levels in children who have Type 1 diabetes. In Type 1 diabetes, children have high blood sugar levels because they do not make enough insulin. The standard treatment is to give insulin either by shots or using an insulin pump. A new device, called closed-loop insulin therapy, uses a continuous glucose monitor (CGMs) linked to an insulin pump by a computer. The CGM will send the sugar levels to a computer which automatically figures out how much insulin to give and then gives that amount of insulin through the insulin pump. It will give the child insulin to bring sugar levels down if they are high, and will give less insulin if the child's blood sugar is getting lower. Earlier research using closed-loop insulin therapy has shown the ability for it to improve diabetes care in adults and older children, but there has been no research of closed-loop insulin therapy in young children. This study will compare children's current insulin therapy with the closed-loop system. The knowledge that the investigators gain from this research will help us to figure out whether closed-loop therapy can work in young children, hopefully leading to better Type 1 diabetes care.
In this protocol the investigators plan to demonstrate the feasibility of a modular insulin management system based on continuous glucose monitoring and targeted towards the avoidance of hypoglycemic and prolonged hyperglycemic episodes (i.e. control to range). The protocol is designed to challenge the insulin management system with meals and mild exercise, so as to demonstrate its capacity to avoid large glucose excursion with changing metabolic state. This system is designed to both - monitor the meal boluses of the patient and correct it in case of observed/predicted under insulinization (avoidance of prolonged hyperglycemia), based on a coarse and subjective knowledge of the meal amount, a precise understanding of the subject's day to day insulin treatment, continuous glucose monitoring, and past insulin injections; - predict and avoid hypoglycemic events, based on continuous glucose reading and past insulin injection. The investigators plan to enroll 12 adult Type 1 Diabetes Mellitus (T1DM) patients (expected retention 10/12) and compare glucose control performances under two treatments: standard vs. the new insulin management system. The protocol will include a total of 6 admissions per subject (4 out-patients and 2 in-patients): screening, effort test, CGM insertion 1, inpatient 1, CGM insertion 2, and inpatient 2. During the 24h inpatient admissions, the patients will be challenged with 30 minutes of mild exercise and 3 meals, insulin coverage of these events will vary depending on the chosen treatment, each subject will be exposed to both studied treatments (repeated measure design).The order of treatment during the inpatient admissions will be randomized.
The purpose of this study is to evaluate the performance of an insulin pump controlling algorithm while the subject is under close medical supervision in the Clinical Research Center (CRC) setting.
People with Type 1 Diabetes Mellitus (T1DM) like to take part in sport and exercise, but problems with metabolism and blood glucose control can make this difficult. Some people with T1DM administer their insulin via an insulin pump, also know as continuous subcutaneous insulin infusion (CSII) therapy, in which a background or basal level of insulin is constantly infused under the skin by a special pump, with bolus doses of insulin given to accompany food. Clinical experience suggests that this may be particularly useful for managing diabetes for exercise, but there is limited experimental evidence to support this. The aim of this research , which is divided into three parts, is to investigate the hypothesis that the physiological response to sub-maximal (moderate) exercise of a person with type 1 diabetes treated with CSII, can be made to approximate more closely to the physiological response of a healthy individual by a prior reduction of their basal insulin infusion rate. This first part of the research is designed to compare metabolic response to exercise between people without diabetes and people with T1DM running there insulin pump at the usual basal rate.
The Pizza-Salami-Study aims to investigate the efficacy of carbohydrate plus fat/protein (CFP) counting compared with carbohydrate (CARB) counting using normal and dual-wave bolus in sensor-augmented pump therapy in children and adolescents with type 1 diabetes. For fat/protein counting the model used by Pankowska et al. will be applied.
