Type 1 Diabetes MellitusAutoimmune DiabetesThe purpose of this study is to investigate the therapeutic effect of Liraglutide on autoimmune diabetes.
Prebiotic Fiber Supplement in T1DM Children
Type 1 DiabetesThe 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.
Cord Blood Infusion for Type 1 Diabetes Mellitus (T1DM)
Type 1 DiabetesChildrenType 1 diabetes (T1D) is still associated with tremendous morbidity and premature mortality. Patients require multiple daily insulin injections throughout their lives as well as close monitoring of their diet and blood sugar levels to prevent complications. Unfortunately, there is presently no permanent cure for diabetes. Whole pancreas or islet cell transplantation is available only to a very limited number of patients and necessitates potential lifelong immunosuppressive therapy. Autologous stem cell transplants have been used successfully for ALL (acute lymphoblastic leukemia), AML (acute myeloblastic leukemia) and for the treatment of a variety of cancers including breast cancer and neuroblastomas, and more recently for the treatment of autoimmune disorders such as multiple sclerosis (MS), lupus-like disease, and rheumatic disorders. Recently it was shown that bone marrow-derived stems cells transplanted into diabetic mice led to reduced hyperglycemia within 7 days after transplantation and was sustained until they were sacrificed at 35 days post-transplantation. The investigators' goal is to transfuse autologous umbilical cord blood into 23 children (Germany 10 and 20 Controls) with T1D in an attempt to regenerate pancreatic islet insulin producing beta cells and improve blood glucose control. As secondary goals, the investigators aim to track the migration of transfused cord blood stem and study the potential changes in metabolism/immune function leading to islet regeneration.
Safety and Efficacy of Mesenchymal Stem Cells in Newly-diagnosed Type 1 Diabetic Patients
Diabetes MellitusInsulin-DependentType 1 diabetes mellitus results from the autoimmune destruction of the insulin producing pancreatic β-cells. The autoimmune response begins months or even years before the presentation of hyperglycemic symptoms. Previous studies with other autoimmune diseases or acute inflammatory diseases testing the effect of the infusion of mesenchymal stem cells showed promising results in regulating immune system and promoting some degree of disease control. The aim of our study is to determine the safety and efficacy of intravenous infusions of mesenchymal stem cells in newly diagnosed type 1 diabetic patients.
Umbilical Mesenchymal Stem Cells and Mononuclear Cells Infusion in Type 1 Diabetes Mellitus
Type 1 Diabetes MellitusUmbilical mesenchymal stem cells (UC-MSCs) infusion is supposed be a promising regeneration therapy with mild side effect as indicated by large quantities of animal experiments and some clinical trials. There are few UC-MSCs clinical trials with regard to diabetes mellitus. The investigators hypothesize that infusion of USC-MSCs may provide multiple signals for beta-cell regeneration and even re-differentiate into local tissues in diabetes mellitus patients, resulting in improvement of diabetic control, of which the effect may be promoted by concomitant infusion of bone marrow mononuclear cells and maximized by intra-arterial pancreatic infusion through angiography.
Joint Application of Human Insulin and Rapid Insulin Analogue in Control of Postprandial Glycemia...
Diabetes MellitusType 1Postprandial glycemic control is essential for diabetes compensation. Insulin pump therapy control blood glucose released in response to both high and low glycemic index carbohydrates in a mixed diet using normal, square and dual-wave boluses. The investigators hypothesize a mixture of rapid insulin analogue and human insulin has the same effect. This pilot prospective cohort study replaces basal-bolus therapy of diabetic subjects by combined prandial application of insulin aspart and human insulin. Mixed-meals with high, both high and low and low glycemic index carbohydrates are covered by 3:1, 1:1 and 1:3 ratios of analogue to human insulin mixture. Subjects are followed by continuous glucose monitor for six days (Phase One), changing between the experimental or their standard protocol for insulin injection on consecutive days. The outcome was measured by comparing average glycemia and areas under the curve of sample meals, which are doughnut, pizza and mixed vegetable salad. The next three-to-four week period of therapy was evaluated by glycated hemoglobin before and after the intervention (Phase Two). Expected outcomes are postprandial and complex improvement of diabetes control, similarly to the insulin pump therapy.
Autologous Transplantation of Mesenchymal Stem Cells for Treatment of Patients With Onset of Type...
Evidence of Liver TransplantationType 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.
Cotransplantation of Islet and Mesenchymal Stem Cell in Type 1 Diabetic Patients
Type 1 Diabetes MellitusThe study evaluates the safety and efficacy of Cotransplantation of Islet and Mesenchymal Stem Cell in Type 1 Diabetic Patients. The researchers hypothesize that additional Mesenchymal Stem Cell infusion can benefit the promising clinical islet transplantation through the following mechanisms: protection of islet from inflammatory damage, immunological modulation, engraftment promotion, thus decrease or eliminate the need of exogenous insulin and improve β-cell function.
Do Sulphonylureas Preserve Cortical Function During Hypoglycaemia?
Type 1 Diabetes MellitusTo see if using medication called sulphonylureas can help improve symptoms which patients rely on to recognise low blood glucose levels ( hypoglycaemia) and also to see if they can reduce the slowing down in brain function which occurs at hypoglycaemia.
