NIH-Supported National Islet Transplantation Registry

Area of Science:

• Transplantation immunology
• Endocrinology
• Regenerative medicine

Background:

• Type 1 diabetes affects 300,000-500,000 individuals in the US, often leading to poorer health outcomes.
• Current management relies on insulin, but islet transplantation offers a potential alternative treatment.
• The growing number of islet transplants necessitates detailed analysis of survival factors.

Purpose of the Study:

• To establish the North American Collaborative Islet Transplant Registry (CITR) for comprehensive data collection.
• To analyze factors influencing patient and graft survival in islet transplantation.
• To enhance the safety and efficacy of islet/beta-cell transplantation.

Main Methods:

• CITR collects data on all North American islet transplants since January 1, 1996.
• An electronic, internet-based system ensures efficient and quality-controlled data entry.
• Data analysis will guide the refinement of transplant protocols.

Main Results:

• Over 22 transplant centers invited to participate, with 7 actively involved and 11 joining.
• CITR aims to publish annual comprehensive reports and periodic special analyses.
• The registry facilitates identification of critical risk factors and determinants of success.

Conclusions:

• CITR is crucial for advancing islet transplantation by providing comprehensive data.
• Improved understanding of risk factors and success determinants will refine transplant protocols.
• The registry supports the development of safer and more effective islet/beta-cell transplantation.
