The study found that, 1 year after islet transplantation, nearly 9 out of 10 transplant recipients had an A1C level below 7 percent and did not have episodes of severe hypoglycemia. Research has shown that clusters of cells called islets (also called islets of Langerhans) from a donor pancreas can be transferred into the liver of a person with diabetes. This new approach was performed with 72 patients who volunteered, all of whom had type I diabetes and "impaired awareness hypoglycemia," which meant that they had incidents of severely low blood sugar that occurred when they weren't aware of it, which can result in a seizure or loss of consciousness. A radiologist uses x-rays and ultrasound to guide the catheter into the portal vein of the liver. Adults (age 18 yrs old or greater) with type 1 diabetes previously treated with islet transplantation who are no longer participating in the original islet transplant treatment study can be considered for study participation.What Will be Done?
