Filter by:The objectives of this study are to: 1. quantitate the level of insulin mRNA in the while cell fraction of whole blood in selected groups of subjects, 2. determine the gene expression of markers of white cell activation in the white cell fraction of whole blood in selected subjects, 3. determine the identity of the white cell responsible for expression of insulin mRNA and 4. determine protein expression of mRNA of insulin/proinsulin and selected genes of white cell activation.
This research project is supported by a multicentric network of collaborators whose goal is to assess the efficacy of transplanting allogenic pancreas islets to restore insulin secretion in patients with brittle type 1, insulin-dependent diabetes mellitus and to improve their metabolic control.
University of Pittsburgh Medical Center (UPMC) diabetes research physicians are studying the action in muscle tissue of "inhaled" insulin (Exubera®) and "infused" (intravenous or IV) insulin on blood sugar control in people with type 1 diabetes. Type 1 diabetics often take 2-4 shots of insulin every day. Exubera may offer an alternative to these insulin injections.
The purposes of this study are: 1. To reverse hyperglycemia and insulin dependency in patients with type 1 diabetes mellitus through islet transplantation utilizing steroid free, calcineurin-inhibitor free immunosuppression. 2. To assess the long-term function of successful islet transplants in patients with type 1 diabetes mellitus utilizing islets that have undergone a period of culture. 3. To determine whether the natural history of the microvascular, macrovascular, and neuropathic complications are altered following the successful transplantation of islets.
The study evaluates the effect of inactivation of the immune system with chemotherapy and immunotherapy and infusion of bone marrow stem cells in early onset type 1 diabetes mellitus. We hypothesize that reprograming the immune system will stop immune aggression to the insulin producing cells allowing their regeneration and thus decreasing or eliminating the need of exogenous insulin.
This study will be the first evaluation of Symlin in adolescent subjects with type 1 diabetes mellitus and is designed to evaluate the blood levels (pharmacokinetics), biochemical and physiological effects (pharmacodynamics), and safety and tolerability of Symlin in these subjects.
While this study is now completely enrolled, we do hope to develop a "next generation" cord blood based study sometime in early 2009. Please continue to contact us if you have a child with newly diagnosed Type 1 Diabetes (T1D) who alo has their OWN cord blood in storage.
The primary objective of the study was to compare the effect of insulin glulisine, insulin lispro and unmodified human insulin on endogenous glucose production during euglycemic glucose clamps using stable labeled glucose in type 1 diabetic subjects. The secondary objectives of the study were to assess: - the effect of insulin glulisine, insulin lispro and unmodified human insulin on plasma nonesterified free fatty acids (NEFA) and glycerol levels - the effect of insulin glulisine, insulin lispro and unmodified human insulin on plasma lactate levels - the safety and tolerability of insulin glulisine in comparison to insulin lispro and unmodified human insulin.
This study was designed to test the safety and efficacy of up to 3 pancreatic alloislet transplants in type 1 diabetic patients with hypoglycemia unawareness. 6 subjects were transplanted under this protocol using anti-thymocyte globulin induction immunosuppression and everolimus with cyclosporine maintenance immunosuppression.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks the insulin-producing beta cells in the pancreas. Without these beta cells, the body cannot maintain proper blood glucose levels in response to daily activities such as eating or exercise. With fewer insulin producing cells blood glucose increases, causing hunger, thirst, and unexplained weight loss. By the time these symptoms develop, 80-90% of a person's beta cells have already been destroyed. However, this also means that between 10-20% of these cells remain that continue to produce insulin. Scientists have learned that two types of immune cells, B cells and T cells, are involved in causing type 1 diabetes. T cells are responsible for attacking and destroying the beta cells that make insulin. Although they don't attack insulin producing cells, B cells may be what trigger the T cells to attack. This study will investigate the use of rituximab to see if it can help lower the number of immune B cells thereby preventing the destruction of any remaining insulin producing beta cells that remain at diagnosis. Rituximab is approved by the Food and Drug Administration (FDA) for the treatment of a condition called B-lymphocyte lymphoma. Its effects on the immune system are well understood through its use in organ transplantation. Research has shown that rituximab might be helpful in treating other conditions caused by T cells and B cells, including type 1 diabetes. The goal of this study is to find out if rituximab can preserve residual insulin secretion and prevent further beta cell destruction in type 1 diabetes.
