Current indications for pancreas or islet transplant

Area of Science:

• Endocrinology
• Transplantation Immunology
• Metabolic Diseases

Background:

• Pancreas and islet transplantation can achieve insulin independence and improve diabetic complications.
• Both procedures necessitate long-term immunosuppression, carrying inherent risks.
• Current outcomes show approximately 80% insulin independence at one year.

Purpose of the Study:

• To evaluate the benefits and risks of pancreas and islet transplantation for managing type 1 diabetes.
• To identify patient subgroups who may benefit most from these interventions.
• To inform clinical decision-making regarding transplantation in diabetic patients.

Main Methods:

• Review of existing literature on pancreas and islet transplantation outcomes.
• Analysis of complication rates and immunosuppression-related risks.
• Assessment of glycaemic control and patient-reported outcomes.

Main Results:

• Pancreas transplantation improves diabetic microvascular complications but involves surgical morbidity.
• Islet transplantation is a lower-risk alternative for patients with severe hypoglycemia or labile diabetes.
• Combined pancreas-after-kidney transplantation is beneficial for difficult-to-control diabetes.
• Transplantation in patients with early renal involvement is experimental and may accelerate renal replacement therapy.

Conclusions:

• Pancreas or islet transplantation can be effective for select diabetic patients, particularly those with severe glycemic instability or complications.
• The decision to transplant should weigh the benefits of glycemic control against the risks of major surgery and immunosuppression.
• Islet transplantation presents a less invasive option for specific patient profiles.
• Transplantation is generally not recommended for patients with well-controlled diabetes and intact renal function due to immunosuppression risks.
