Effects of Gluten Free Diet on Type 1 Diabetes Mellitus in Children
Type 1 Diabetes MellitusThe central hypothesis of this proposal is that a gluten-free diet introduced shortly after diagnosis can reverse or arrest islet destruction in children and adolescents with type 1 diabetes mellitus (T1DM). The specific aims are to determine the effects of a gluten-free diet on 1) endogenous insulin production and 2) the corresponding gut flora of children with new-onset type 1 diabetes. This is a randomized placebo controlled clinical trial testing the effect of altering the gut microbiome via a gluten-free diet on endogenous insulin production as a measure of the pace and severity of islet destruction at the time of diagnosis of type 1 diabetes. The project entails eliminating gluten from the diet of the intervention group and comparing bacterial gut flora and endogenous insulin response with those in a control group up to one year following the diagnosis of type 1 diabetes. The proposal introduces a new potential etiology for type 1 diabetes in humans: the Bacterial Hypothesis. The short term goal is to identify specific islet-preserving microbiome changes induced by eliminating gluten from the diet of patients recently diagnosed with type 1 diabetes. The long term goal is to develop these changes into effective and safe strategies that can allow patients with type 1 diabetes to achieve permanent insulin-independence.
The GlucoPred Investigation II
Diabetes MellitusType 1Diabetes mellitus type 1 (DM1) is an autoimmune metabolic disease in which the insulin producing cells in the pancreas are destroyed and the subject is left totally dependent of external supply of insulin. There is no known cure for DM1 except for in very specific situations. Thus, management of DM1 concentrates on keeping blood glucose levels as close to normal levels. As an aid to subjects with DM1 for managing their blood glucose levels as close to normal as possible, blood glucose monitoring systems have been developed. Available blood glucose monitoring systems today require a capillary blood sample that is analysed by a glucose meter. Subjects are normally advised by health care professionals on the appropriate blood glucose monitoring regime for their condition. However, many subjects fail to measure blood glucose as often as needed to achieve good blood glucose control despite every effort from health care professionals. Research and development of non-invasive interstitial blood glucose monitoring methods is ongoing. All attempts to develop a non-invasive continuous glucose measuring device have so far failed. Prediktor Medical AS has developed a non-invasive sensor, GlucoPred, based on the combination of several non-invasive measurement principles and multivariate analysis and dynamic models of glucose/insulin interaction. The device will be body mounted in the form of a bracelet or a watch communicating with a mobile phone or a tablet for data presentation and collection. Development of GlucoPred is now at a stage where testing of the sensor in subjects under controlled settings is required before further development can take place. If successful, this will be a major step ahead for all patients with diabetes and markedly increase their possibility to take care of their disease on a day to day basis without the burden of frequent blood sampling or wearing an invasive device.
Evaluation of Automated Insulin Pump Settings Using the Advisor Pro (Previously Called) MD-Logic...
Type 1 DiabetesPump therapy is gaining popularity as a treatment mode for patients with type 1 diabetes. Utilizing pump therapy requires the development and application of a new spectrum of theoretical knowledge and practical skills by the patient. Furthermore, occasionally there is a need to tailor the pump settings, i.e. the insulin correction factor, carbohydrate ratio, basal plan and insulin activity time, in order to optimize and improve glucose control. These adjustments are based on collected information including insulin delivery, blood glucose measurements, continuous glucose monitoring data, meals and so on. Analyzing this multitude of information and data is overwhelming for many of the patients, caregivers and health care providers. Unfortunately, not all physicians have the needed expertise to fully fulfill this task, and for those who do, it is time consuming. Thus, a summary of the data with insulin dose adjustment suggestions is missing. An automated tool for pump setting adjustments will improve glycemic control without escalating the burden on patients and the health care system. Such advisor can assist the professional team during routine follow-up and the patients between visits. To address this challenge, the investigators developed the MD-Logic Pump Advisor (MDPA), which automatically analyses treatment information, learns patient's needs and accordingly suggests adjustments in insulin dosing. The MDPA uses information gathered from glucose monitoring, insulin dosing and meal data during daily routine home care. Following a 5 minute data collection and analysis, the algorithm learns and suggests pump-setting changes for optimization of glucose control. This study aims to evaluate the efficacy and safety of the Advisor Pro. The study will include three segments: Segment A - a randomized controlled parallel study, Segment B- a clinic prospective study during which the Advisor Pro will be evaluated during routine clinical visits as an added tool for physicians and Segment C- a clinical prospective parallel study for patients treated with pump therapy and SMBG only.

Secondary Objective: To evaluate the appropriate utilization of virtual approach via novel technologies during the study and to assess the effect of the virtual versus traditional study conduct on multiple outcomes in terms of study methodology and diabetes management.
Safety and Efficacy of Chlorthalidone in Type 1 Diabetes
Type 1 Diabetes MellitusHypercalciuriaThis open-label study will determine if chlorthalidone is safe and effective for the use of reducing urinary calcium excretion over 4 weeks in subjects with type 1 diabetes
Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Oral Insulin (IN-105) in Type 1 Diabetes...
Type 1 Diabetes MellitusThe purpose of this study is to see whether IN-105 (oral insulin) is able to control increase in blood glucose after eating a meal. This study will also tell whether single tablet of IN-105 is safe for patients with Type 1 diabetes mellitus who are currently taking insulin injections.
The Effect of Pancreatic Polypeptide on Insulin Requirements for Type 1 & Post-pancreatectomy Diabetic...
Diabetes MellitusType 1The goal of this research is to see if pancreatic polypeptide (PP), a hormone that is naturally produced by the pancreas and that works to control the amount of glucose that the liver makes, will reduce the amount of insulin required for people who must take insulin to maintain their normal blood glucose level.

Islet Transplantation for Type 1 Diabetes Mellitus
Type 1 Diabetes MellitusThe complex program of insulin replacement for type 1 diabetes that is current clinical standard of care is difficult to implement for long periods of time, associated with an increased risk of severe hypoglycemia and implemented by less than 50 % of the population of such patients. Outcomes of transplantation of isolated human islets have substantially improved and been performed at about 40 institutions around the world. We are proposing a clinical phase 1/phase 2 study of islet transplantation alone evaluating safety and efficacy in five patients with type 1 diabetes. Islet isolation from deceased donor pancreases will be performed at the Mayo Rochester Islet Isolation facility and islets infused by Interventional Radiology into the portal venous system. Following islet infusion, patients will be hospitalized for 48 hours in the General Clinical Research Center (GCRC) or at the Rochester Methodist Hospital. Multiple safety and efficacy outcomes will be followed on multiple occasions during the first year and periodically thereafter.
TEDDY - The Environmental Determinants of Diabetes in the Young
Type 1 Diabetes MellitusThe long-term goal of the TEDDY study is the identification of infectious agents, dietary factors, or other environmental agents, including psychosocial factors which trigger T1DM in genetically susceptible individuals or which protect against the disease. Identification of such factors will lead to a better understanding of disease pathogenesis and result in new strategies to prevent, delay or reverse T1DM.
