Collaborative iIslet Transplant Registry.
The Collaborative Islet Transplant Registry (CITR) was established in 2001 with support from the National Institute of Diabetes and Digestive Diseases to collect and analyze information on islet transplants in North America. Thirteen of 27 invited islet transplant centers from the United States and Canada were already participants as of January 2004 with 5 additional centers awaiting IRB approval. In October 2003, CITR had preliminary data on 58 recipients of 107 islet transplants performed at the 13 member centers. These islet recipients averaged 41 years of age (SD 8.9), had diabetes for almost 28 years (SD 10.2) and were predominantly (67%) female. Islets were procured from 118 deceased donors whose average age was 42 (SD 12.2), weight was 90 kg (SD 23.5), and BMI was 30.5 (SD 7.9). The time from cross-clamp to pancreas recovery averaged 56 minutes (SD 134.6). An average of 7,127 islets (SD 2,973) were infused per kg of the recipient's weight. Outcome data are still pending as the Registry prepares its first annual report. Here we describe the organization, goals and design of the data collection instruments for CITR.
