[Kidney transplantation in Italy: an evolving scenario].

Background: Italian transplantation systems have dramatically improved in the last decade. Kidney transplantations are now strictly monitored and excellent results has been achieved in terms of quality and the ability to reduce waiting times for receiving transplantation.

Methods: The Italian organizational retrieval and transplant system is articulated on four levels: local, regional, inter-regional and national. The Italian Transplant Information System (SIT) was set up in 2000 in accordance with Law 91/99. Patient data on the waiting lists and follow-up of transplanted patients are routinely collected.

Results: A total of 4406 kidney transplants have been carried out in the 40 Italian kidney transplant centers in 2001-2003. The survival analysis was conducted for the 2000-2002 in 4222 cases. Overall 1-yr survival was 92.4% for the graft and 97% for the patients. After adjusting for variables independently associated with the outcome at multivariate analysis (for example, the case-mix), patient and graft survival at 1 yr was 98.1% and 93.8%, respectively. No remarkable differences in 1-yr graft survival were observed between the 40 Italian kidney transplant centers. At multivariate analysis, variables independently associated with graft failure were donor age, degree of HLA mismatch and recipient case-mix. Analysis of the waiting list showed approximately 6500 patients waiting for kidney transplantation. The mean waiting time was 3.04 yrs, with a mortality rate of 1.18% per year.

Conclusions: Kidney transplantation activity in Italy has produced excellent results in terms of quality and number of transplants per year. However, the number of patients on the waiting list and the waiting time call for further action to increase the number of available organs.
