Type 1 Diabetic
Conditions
Brief summary
The purpose of this study is to determine if islet cell transplantation , is an effective treatment for type 1 diabetes. Study participants may receive up to three islet transplants and will be followed for five years to monitor blood sugar control, islet transplant function, and changes in quality of life.
Interventions
Allogeneic transplantation of intrahepatic islet is one of the effective methods for diabetic therapy

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Obtaining an improvement in glycemic control | nine months after first and last islet transplants | The proportion of subjects with an HbA1c ≤ 6.5% and free of severe hypoglycemic events |
| normal glycemic control without insulin | 3 months after graf | A fasting glucose (\> 8 hours) less than 1.25 g/L and a 2 hours glucose after oral intake of 75g of glucose, less than 2 g/L in a patient without insulin for at least 15 consecutive days during the the first 6 months |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| insulin independence | One year after the last transplant | insulin independence |
| Hypoglycemic episodes by HYPO score | 3 months after transplantation | Hypoglycemic episodes by HYPO score |
| degenerative complications of diabetes | 18 months after transplantation | degenerative complications of diabetes |
