Rapid Publication Clinical Outcomes and Insulin Secretion After Islet Transplantation With the Edmonton Protocol

Islet transplantation offers the prospect of good glyce-mic control without major surgical risks. After our initial report of successful islet transplantation, we now provide further data on 12 type 1 diabetic patients with brittle diabetes or problems with hypoglycemia previous to 1 November 2000. Details of metabolic control, acute complications associated with islet transplantation, and long-term complications related to immunosuppression therapy and diabetes were noted. Insulin secretion, both acute and over 30 min, was determined after intravenous glucose tolerance tests (IVGTTs). The median follow-up was 10.2 months (CI 6.5–17.4), and the longest was 20 months. Glucose control was stable, with pretransplant fasting and meal tolerance–stimulated glucose levels of 12.5 6 1.9 and 20.0 6 2.7 mmol/l, respectively, but de
