Abstract

Background

In this study, we have reported updated statistics of the Iranian Transplantation Registry, the status of the recipients and grafts, and a detailed time trend with respect to patient characteristics.

Methods

We retrospectively reviewed the Iranian Renal Transplantation Registry and information from the Dialysis and Transplant Patients Public Association, to obtain data on all kidney transplantations performed in Iran between 1986 and 2005. Data were gathered regarding the total number of transplantations, graft loss, recipient death, and donor and recipient characteristics, including demographic data, cause of end-stage renal disease (ESRD), and source of kidney. We assessed changes in variables on a biannual basis.

Results

A total of 19521 transplantations were registered over the study period, of which, 761 recipients (3.9%) had died and 2333 allografts (11.9%) had been lost. The source of the kidney in 2556 (13%) subjects was a living related donor (LRD), in 16234 (83%) a living unrelated donor (LURD), and in 831 (4%) cadaveric. During the study decades we noted an increase in the number of kidney transplantations (from 22 to 3690), age of recipients (from 30 to 40), male-to-female ratio of recipients (from 0.58 to 0.67), male-to-female ratio of donors (from 0.48 to 0.52), diabetes mellitus (from 0% to 27%), and hypertension (from 4% to 15%), as causes of ESRD, as well as the use of cadaveric kidneys (0% to 11%).

Conclusion

Analyzing renal transplantation data not only helps to evaluate the effectiveness of transplantation activities in a country, but also provides information to estimate future costs in the health care system.

Materials and Methods

In a retrospective study, we reviewed the Iranian renal transplantation registry data of all renal transplant patients in Iran between 1986 and 2005. We extracted data from Dialysis and Transplant Patients Public Association. We recorded data of kidney donors and recipients, including age, sex, donor type, and cause of ESRD such as diabetes and hypertension. Hospital-based data on the number of annual transplantations, rejection, and death were also collected.

Data were analyzed using SPSS

Results

The 19,521 kidney recipients and donors, showed a mean age of 38.5 years (range, 30 to 40 years) and 28.86 years (range, 27 to 38 years), respectively. The source of the kidney was living related donor in 2556 (13%) cases, living unrelated donor (LURD) in 16,234 (83%), and cadaveric in 831 (4%). Among recipients, 12,063 (61.8%) were men and 7458 (38.2%), women.

Of all patients, 761 recipients (3.9%) died and 2333 allografts (11.9%) were lost. During the study decades, we noted an increase in the

Discussion

According to the statistics presented here, at the start of 2006, among 19,521 kidney recipients, 16,427 subjects with functioning grafts were receiving health care services in Iran. The transplantation rate in our country shows an increasing trend, in line with the developments in transplantation, with some changes in demographic and clinical variables trending toward a higher age and a larger number of patients with complex causes of ESRD, such as diabetes mellitus and hypertension.
