Pancreas Volume in Preclinical Type 1 Diabetes

Type 1 diabetes (T1D) is characterized by a progressive destruction of insulin producing beta cells, resulting in a lifelong dependence on exogenous insulin. While beta cells make up less than 1% of the pancreas, studies have demonstrated that T1D is associated with a marked reduction of pancreatic mass at diagnosis and as the disease progresses. As such, if pancreatic volume assessment, by ultrasonography (US) or MRI (Magnetic Resonance Imaging), could be utilized as a marker of beta cell function in high risk patients, non-invasive pancreatic imaging could become an important part of staging diabetes risk. As such, the primary goal of this study is to measure pancreatic volume and compare differences in volume between new onset T1D patients, antibody positive subjects at risk for diabetes, antibody negative individuals, and healthy controls.

Effect of Metformin on Vascular and Mitochondrial Function in Type 1 Diabetes

Insulin resistance (IR) is an important contributor to increased cardiovascular disease risk in type 1 diabetes (T1D). The purpose of this study is to measure the effect of metformin on insulin sensitivity, vascular function and compliance, and mitochondrial function in T1D. The long term goal is to identify novel non-glycemic approaches to managing cardiovascular disease risk in T1D. The results of this study may validate a novel approach to T1D treatment that could significantly improve current management of cardiovascular disease risk in this high risk population.

Oral Hypoglycemic Therapy for Monogenic Variant Carriers of the Joslin Medalist Study

The purpose of this study is to evaluate the efficacy of adding oral hypoglycemic agents (OHA) to existing insulin treatment in monogenic variant carriers of the Joslin 50-Year Medalist Study ("Medalists"), who are characterized by ?50 years of insulin-dependent diabetes. Our primary objective is to evaluate whether the presence of human leukocyte antigen (HLA) high-risk alleles for diabetes (DR3 and/or DR4) can affect the effectiveness of OHA in these subjects.

Prevention av Autoimmunitet Med Laktobaciller

The incidence of autoimmune diseases (celiac disease, type 1 diabetes, thyroid disease) have increased over the past 30 years. Although most autoimmune diseases have a strong link to different risk genes, the rapid increase is thought to be due to changes in environmental factors. There is currently no cure for autoimmune diseases, but the treatment is lifelong and either involves suppressing the inflammation and / or substituting the organs that are affected to maintain vital functions. Being able to predict who is affected and identifying factors that trigger autoimmunity is necessary for developing new treatment methods that prevent the occurrence of autoimmune diseases. The bacterial flora's composition in the gut can affect both the intestinal barrier properties and the immune system's response to various dietary components. An adverse composition of the intestinal flora can activate parts of the immune system that are involved in chronic inflammation in celiac disease and inflammatory bowel disease. Probiotics are defined as living microorganisms which, when ingested in sufficient amounts, produce a health effect (FAO / WHO). The aim of the study is to investigate whether a daily oral intake of a mixture of L.paracasei and L.plantarum can affect the autoimmune process in children who are screened positive for any of the autoantibodies associated with development of celiac disease, type 1 diabetes and / or thyroid disease. Our hypothesis is that lactobacilli can directly regulate the autoimmune process in the small intestinal mucosa by stimulating regulatory T-cells, but also by affecting the permeability of the small intestinal mucosa by of antigen that stimulates specific T-cells.

The Insulin-Only Bionic Pancreas Pivotal Trial

This multi-center randomized control trial (RCT) will compare efficacy and safety endpoints using the insulin-only configuration of the iLet Bionic Pancreas (BP) System versus Usual Care (UC) during a 13-week study period. Participants may be enrolled initially into a screening protocol and then transfer into the RCT protocol, or they may enter directly into the RCT protocol. The RCT will be followed by an Extension Phase in which the RCT Usual Care (UC) Group will use the insulin-only configuration of the iLet Bionic Pancreas System for 3 months. At the completion of use of the BP system (end of RCT for BP Group and end of Extension Phase for UC Group), participants will enter a 2-4 day Transition Phase and be randomly assigned to either transition back to their usual mode of therapy (MDI or pump therapy) based on therapeutic guidance from the iLet BP System or transition back to their usual mode of therapy based on what their own insulin regimens were prior to enrolling in the RCT.

Low-dose rhIL-2 in Patients With Recently-diagnosed Type 1 Diabetes

Type 1diabetes (T1D) is caused by autoimmune destruction of the pancreatic islet ß-cells, leading to an absolute deficiency in insulin. In health, regulatory T cells (Tregs) suppress immune responses against normal tissues, and likewise prevent autoimmune diseases. Tregs are insufficient in T1D. The investigators previously showed that administration of low doses of IL-2 induces selective expansion and activation of Tregs in mice and humans. The investigators hypothesize that Tregs expansion and activation with low doses of IL2 could block the ongoing autoimmune destruction of insulin producing cells in patients with recently diagnosed T1D.

CGM Use in Poorly Controlled Youth With Type 1 Diabetes

The purpose of this prospective study is to determine if trial use of a Dexcom G6 CGM system for a 10 day wear period in high risk, poorly controlled pediatric Type 1 diabetes patients increases uptake of personal CGM use, and improves short-term time in range glucose control.

Insul-In This Together Program for Adolescents With Type 1 Diabetes and Their Parents

The "Insul-In This Together" intervention is designed for teens with Type 1 Diabetes and their parents. This study seeks to evaluate an evidence-based family intervention for teens with type 1 diabetes and their parents to offset the psychosocial and diabetes self-management risks. This information will provide a more in-depth understanding of family-based program efficacy for teens with adolescents and provide more judicious and streamlined intervention options to be offered in diabetes clinics in the future.

Prolonged Fasting on Glucose Metabolism and Hormonal Regulation in Healthy, Obese and Subjects With Type 2 Diabetes

In a previous study investigating the effects of intermittent fasting, our research group found evidence for higher glucose excursions and a reduced insulin response after a 36 hour fasting period as compared to an overnight fasting period in healthy subjects. The aim of this research project is to investigate the effect of short and midterm fasting (12 hours versus 36 hours) on glucose metabolism, glucose regulatory hormones, insulin secretion and resting energy expenditure in healthy and obese people as well as in patients with type 2 diabetes.

Guided User-initiated Insulin Dose Enhancements (GUIDE) to Improve Outcomes for Youth With Type 1 Diabetes

We propose conducting a pilot randomized study to assess the feasibility of using the automated insulin dose adjustment (AIDA) system to assist the parents of children with Type 1 Diabetes to make insulin dose adjustments between visits with their diabetes provider. Study results will be used to inform a larger RCT with an anticipated primary outcome of change in HbA1c in patients managed with either standard care (changes in therapy settings effected at regularly scheduled patients visits) or AIDA guided care.
