Active clinical trials for "Diabetes Mellitus, Type 1"

The purpose of this study is to investigate the therapeutic effect of Liraglutide on autoimmune diabetes.

Type 1 diabetes is an autoimmune disorder characterized by beta cell destruction resulting in insulinopenia. Currently it is being treated with insulin. Dipeptidylpeptidase inhibitors (DPP4 inhibitors e.g. linagliptin & sitagliptin) has been used for type 2 diabetes mellitus (T2DM) traditionally. Previous studies has shown that it is also effective in type 1 diabetes mellitus (T1DM), but the mechanism of action not well understood. This study will evaluate possible mechanism of action of linagliptin in T1DM patients.

The gut microbiome is increasingly recognized as a contributor to disease states. In type 1 diabetes, alterations in gut microbiota may be linked to changes in intestinal permeability, inflammation and insulin resistance. Prebiotic fiber is a dietary supplement that alters gut microbiota and could potentially improve insulin sensitivity in children with type 1 diabetes. This pilot study aims to determine the feasibility of a 12-week dietary intervention with prebiotic fiber in children with type 1 diabetes. The investigators hypothesize that consumption of prebiotic fiber will alter gut microbiota and intestinal permeability, leading to improved glycemic control. Prebiotic fiber is a potentially novel, inexpensive, low-risk treatment addition for type 1 diabetes that may improve glycemic control by changes in gut microbiota, gut permeability and inflammation.

This study is a multicenter, randomized, double-masked, placebo-controlled clinical study. All groups will receive standard intensive diabetes treatment with insulin and life style management. 60 subjects will be randomly assigned in a 1:1:1 ratio to receive placebo or different dosage of GABA. GABA is an amino acid produced from glutamate by glutamic acid decarboxylase. It was approved for the treatment of hepatic coma, fibromyalgia, ataxia in China and is widely used as supplement for the treatment of epilepsy, insomnia, stress and tobacco dependence. It has been recently shown that GABA can prevent and reverse the development of diabetes in type 1 mice models. Participants will receive placebo or GABA for 52 weeks. The study will consist of 4 weeks screening period, 2 weeks run-in period, 52 weeks treatment period and 4 weeks follow-up period. Enrollment is expected to occur over 2 years. To assess the efficacy and safety of GABA for the treatment of juvenile type 1 diabetes in new onset subjects.

This study combines data collection and simulation-based education, and it will enroll up to 36 adults with T1DM who already have experience with insulin pump therapy and some experience with a continuous glucose monitor (CGM). The study will first track participants for of a 3-day CGM-training period. The training period will be followed by a 1-week CGM monitoring and CGM data collection period. Following the 1-week CGM monitoring-only portion of the study, participants will begin the education intervention component of the study, referred to as Insight-Based Online Learning Using Simulation and Education for Diabetes (iBOLUSED). The education intervention component is 4 weeks in length. The intervention will involve daily diary data upload and daily simulation-based feedback based on the collected diary data. During the first week (and for up to 2 weeks) of the intervention, participants will view glycemic outcome data that represents the participant's hypo- and hyperglycemic risk throughout the day, based on the CGM data collected during the CGM monitoring period. In the next 2 weeks of the intervention, participants will have an opportunity to interact with the internet-based system using a simulation-based tool designed to provide insight to the participant regarding the different effects of modifications to insulin therapy. Throughout the educational intervention, participants will record diary data every day through the use of a diary component in the internet-based system. Diary entries include data on meals, physical activity, history of the insulin basal rate and insulin boluses given that day, self-reported stress level, hypo- and hyperglycemic fear levels, and, if applicable, menstrual cycle and any physical illness. Participants will also upload data from the CGM via the Dexcom Data Manager 3 (DM3) software or the Dexcom Studio Software. Two assessments, one prior to the intervention period and one following the intervention, will be administered to gather relevant psychobehavioral information. Focus group sessions will be conducted at the end of the study, which will allow for the collection of information regarding the effectiveness of the Internet intervention and will provide insight for the design of future studies. Parallel recording of CGM, insulin, and behavioral data, as well as psychometric instruments, will produce a rich synchronized data set for each person that will facilitate the development of personalized behavioral profiles that will be employed to provide individualized feedback to educate participants. In particular, this study tests the use of collected diary data to educate participants by describing glucose profile information and presenting relevant data regarding: (1) hypo- and hyperglycemia risk zones throughout the day, (2) insulin meal bolus information and associated glycemic outcome indices, and (3) basal rate information with associated glycemic outcome indices.

The intent of this clinical study is to answer the questions: 1) is the proposed treatment feasible; 2) is treatment effective in improving the disease pathology of patients with diagnosed diabetic erectile dysfunction.

This study evaluates the delivery of substance P via the celiac artery in the treatment of recent onset type 1 diabetes.

Nocturnal hypertension is recognized via ambulatory blood pressure monitoring in adolescents with type 1 diabetes mellitus. Melatonin, (as previously seen in earlier studies in adults), may alter these changes, which may be a benefit especially for patients with diabetes mellitus who are at risk for cardiovascular changes. The purpose of this study is to estimate the use of melatonin as treatment for nocturnal hypertension in young adults with type 1 diabetes melitus.

Diabetes mellitus in children and adolescents is a source of stress and poor quality of life for themselves and their family. Development of adaptive coping strategies may be improved by focused parent and children training. This study assesses a cognitive behavioral treatment (CBT) for children/adolescents with diabetes and their parents in comparison with standard health educational interventions. The investigators main aim is to verify that the CBT program improves overall balance of glycaemia better than phone contact without CBT content (control group). Secondary objectives are expected improvements of health-related quality of life and coping styles in parents and children.

Type 1 diabetes mellitus (T1DM)is characterized by the autoimmune destruction of the pancreatic β cells; as a result, patients with T1DM are dependent on exogenous insulin to control their blood glucose continuously. Bone marrow-derived mesenchymal stem cells has been shown in many animal studies their potential cure for T1DM,which could not only address the need for β-cell replacement but also control of the autoimmune response to cells which express insulin. Therefore it is need to study the safety and efficacy of autologous bone marrow mesenchymal stem cells in treatment of newly diagnosed patients with T1DM.
