Active clinical trials for "Diabetes Mellitus, Type 1"

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 primary objective of this study is to compare the 2-hour PPBG excursion following a standard test meal in insulin-requiring diabetic patients treated twice daily with human insulin mix 50/50, versus the 2-hour PPBG excursion in patients treated twice daily with insulin lispro mix 50/50.

In this study, we plan to examine the difference in effect on blood glucose control in patients who will be on either conventional insulin therapy (i.e. using NPH and Humalog twice daily, injected separately) or on intensive insulin management (IIM-several shots of short acting and Glargine insulin). Those on IIM will be mixing the insulin Glargine with the short-acting insulin analog prior to injecting. The Hemoglobin A1c (HbA1c) results will be used to monitor blood glucose control over a 6 month period. Twice during the course of the study, a continuous glucose monitoring system (CGMS-a device the size of a pager that records blood sugar readings every 5 minutes) will be used to record all the changes in the blood glucose levels occurring over a 72-hour period.

Dialysis patients suffer from many problems with blood vessels and this is even more so for patients with the added complication of diabetes. Diabetics have a number of reasons for vascular disease and one of the new areas of research is looking at the cells that line the blood vessels, called endothelial cells. It is thought that the number of red blood cells in the blood (haemoglobin concentration) affects the function of these cells. There is very little information available on what haemoglobin level is best for dialysis patients. As diabetics account for almost 40% of dialysis patients worldwide it is important to understand the effect different haemoglobin levels will have on the blood vessels. Hypothesis: Endothelial cell function and the related expansile capacity of blood vessels are affected by different haemoglobin concentrations [Hb] in dialysis patients.

Pulmonary Safety in Diabetics with T/I

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.

To determine and compare the efficacy of Tacrolimus/Rapa versus Tacrolimus/MMF-based immunosuppression (in conjunction with initial short-term steroids and polyclonal antibody administration) in Type 1-diabetic patients undergoing simultaneous pancreas/kidney allograft transplantation. To evaluate the safety of Tacrolimus/Rapa versus Tacrolimus/MMF in terms of drug-related complications and overimmunosuppression-associated complications, particularly under monitoring of the pharmacokinetic profile of all drugs administered.

Insulin is a chemical that the body needs in order to use or store sugar. It is made by a type of cell called a beta cell which resides in an organ known as the pancreas. Type 1 diabetes is a disease where the beta cells have been destroyed so that little or no insulin is made. Sugar levels rise in the blood as a result. INGAP-Peptide is being tested to attempt to create new beta cells in the pancreas, and to restore the ability to produce insulin in type 1 diabetic patients.

The purpose of this protocol is to determine if an investigational drug known as LY333531 is effective in treating nerve malfunction in diabetes.

This is a randomized, open-label, crossover study to examine the bioavailability of pramlintide in normal weight and overweight subjects with type 1 and type 2 diabetes mellitus using insulin.
