Filter by:The purpose of this study is to see if giving pramlintide and insulin before a meal would lower high blood sugar and if a glucagon (a naturally made hormone in the body but reduced in diabetes and its role is in prevention of low blood sugar) shot given in the late "after meal" time would prevent low blood sugar. The studies outlined in this proposal might help in developing new treatment options to target "after meal" high blood sugar and before meal low blood sugar in children. This would possibly help improve overall blood sugar control and prevent the long-term complications of diabetes.
Islet transplantation has been investigated as a treatment for Type 1 diabetes mellitus in selected patients with inadequate glucose control despite insulin therapy. However, the perennial hope that such an approach would result in long-term freedom from the need for exogenous insulin, with stabilization of the secondary complications of diabetes, has failed to materialize in practice. The goal of the present study is therefore to improve the safety and efficacy of clinical islet-alone transplantation by minimizing dependence on calcineurin-inhibitor therapy - thereby avoiding potential nephrotoxicity, and furthermore improving success with single-donor islet infusions by avoiding all diabetogenic immunosuppression. Campath-1H, combined with Infliximab induction therapy provides a unique opportunity to minimize dosing of maintenance long-term immunosuppression while further promoting islet engraftment.
Our experience suggests that further research with alemtuzumab is attractive in islet transplantation. Therefore, in this study we propose to combine alemtuzumab induction pre-transplant, with tacrolimus and mycophenolate mofetil maintenance immunosuppression post-transplant. In the critical early phase post transplant, we anticipate that this regimen will prove to be more effective in control of autoimmunity or rejection events, and have a more desirable side-effect profile, than previously tested combinations of induction and immunosuppressive agents.

Performance of self-care recommendations is key to the successful treatment of diabetes. However, many patients have difficulty adhering to diabetes self-care recommendations. Recent results from our own studies and others have identified specific barriers to diabetes self-care. To evaluate the efficacy of a diabetes educator-led group intervention, the Breaking Down Barriers Program, that addresses barriers and therefore leads to improved adherence to diabetes self-care recommendations, we will randomize 222 (111 type 1 and 111 type 2) diabetes patients to one of three conditions: 1) the Breaking Down Barriers Program, 2) a cholesterol attention control condition, or 3) a 'usual care' control condition. We hypothesize that those assigned to the Breaking Down Barriers group will improve self-care behaviors and glycemic control more than those in the two control groups. We will follow study subjects for one year to determine whether their self-care behaviors and glycemic control improved and if the improvement was maintained over time.
Type 1 diabetes is a common chronic disease of childhood. It is not yet preventable. Multiple daily injections of insulin, tests of blood sugar, and careful dietary planning are required lifelong to prevent long-term complications such as blindness and kidney failure. Recent studies of potential risk factors in children with diabetes, along with studies revealing the immunologic properties of vitamin D, and experiments in animals suggest higher doses of vitamin D may prevent type 1 diabetes. For proof for human children, a randomized trial will compare groups at risk randomly assigned to receive either the usual vitamin D supplement or a higher amount, 2000 IU daily. This initial study is a small scale test of procedures.
