Pancreas transplantation: review.

Area of Science:

• Transplantation Medicine
• Endocrinology
• Nephrology

Background:

• Pancreas transplantation (PTx) is the sole curative treatment for diabetes, normalizing glucose levels.
• Diabetic complications significantly impact patient quality of life and longevity.

Purpose of the Study:

• To review and analyze graft and patient survival rates following pancreas transplantation.
• To assess the impact of PTx on the reversal of diabetic complications.
• To compare different PTx models: simultaneous pancreas-kidney (SPK), pancreas after kidney (PAK), and PTx alone.

Main Methods:

• Systematic review and analysis of existing literature on pancreas transplantation outcomes.
• Evaluation of graft survival data at 1, 5, and 10 years post-transplant.
• Assessment of patient survival rates at 1 year for different transplant types.
• Analysis of the effects of PTx on diabetic microvascular and macrovascular complications.

Main Results:

• Graft survival rates at 1 year: 82-98% (SPK), 71% (PAK), 62% (PTx alone). 5-year survival: 90% (SPK). 10-year survival: 75-54% (SPK).
• Patient survival rates at 1 year: 96.9% (SPK), 96.3% (PAK), 98.3% (PTx alone).
• Pancreas transplantation generally improves or reverses diabetic complications. SPK demonstrated the most effective outcomes.

Conclusions:

• Pancreas transplantation is a viable, albeit morbid, alternative to conventional insulin therapy for managing diabetes.
• SPK transplantation is the most effective model, offering significant benefits in graft and patient survival and complication reversal.
• Challenges include surgical complications and the lifelong requirement for immunosuppression, limiting wider application.
