The purpose

Intensive control of Type 1 Diabetes is critical in prevention of long term complications. Unfortunately, there is a three-fold increase in hypoglycemia with intensive control. Hypoglycemia is often the major limiting factor in achieving good control. Insulin treatment of diabetes is composed of some form of short acting insulin regimen in order to provide control of blood glucose excursions that are the result of glucose intake as well as a basal insulin regimen either in a continuous administration (as in continuous subcutaneous insulin infusion-"pump therapy"), once a day injection (insulin Glargine), twice a day (ultralente or NPH or lente insulin) or a premixed version that is combined with the short acting insulin (70/30 or 75/25). Often low blood sugars are the result of less physiologically absorbed insulins whose peak of action is earlier or later than the peak absorption of glucose from a meal. Apidra (glulisine insulin) is a new short acting insulin analogue whose peak and duration of action are ideal in that it may be administered more appropriately prior to and even after a meal with evidence of good control of blood glucose excursions from a meal. The purpose of this study is to compare the effect of Apidra upon meal related blood glucose profile as compared to those treated with 70/30 insulin in patients with Type 1 Diabetes. The investigators also will study healthy volunteers as controls who will not be treated with insulin but will be evaluated for mealtime absorption and blood glucose profile during similar meal intake. The investigators will use a stable isotope tritiated glucose.
