Currently, the buying and selling of kidneys through "transplant tourism" is occurring at an increasing rate, both in developed and developing countries. Since 1988, Iran has adopted a compensated and regulated living-unrelated donor renal transplant program, and by providing financial incentives to volunteer living donors, has eliminated the renal transplant waiting list. In the Iranian model of renal transplantation program, regulations have been put in place to prevent transplant tourism. Foreigners are not allowed to undergo renal transplantation from Iranian living-unrelated donors. They also are not permitted to volunteer as kidney donors for Iranian patients. A study at the transplant unit of Hashemi Nejad Kidney Hospital in Tehran, Iran, showed that of 1881 renal transplant recipients, 19 (1%) were Afghani or Iraqi refugees, 11 (0.6%) were other foreign nationals, and 18 (0.9%) were Iranian immigrants. Renal transplantations seemed ethically acceptable to all refugees and foreign nationals. However, transplantation of Iranian immigrants who had been residing abroad for years constituted true transplant tourism.

Noncompliance with immunosuppressive medications in renal transplant recipients results in higher rate of acute rejection episodes, allograft dysfunction, graft loss and patient death. We studied incidence and risk factors of medications noncompliance in 286 renal transplant recipients who were consecutively seen in our renal transplant clinic between February and April 2002. One hundred and seventy were male, 116 female. Their age ranged from 12 to 70 years (mean 39.1+/-11.6). The length of time since the date of transplantation ranged from 5 to 231 months (mean 76.7+/-53.5). The results of study showed that 70 patients (24.5%) to be noncompliant (7.7% noncompliant minor and 16.8% noncompliant major). The time since the date of transplanation was a significant risk factor in both noncompliant minor and major groups (P0.001 and P0.001). The other risk factors associated with major noncompliance was young age (P0.001), lower level of education (P0.01), lower socioeconomic class (P0.05), addiction and psychiatric disorders (P0.05). Transplant recipients with major noncompliance also had more acute rejection episodes (P0.001) and allograft dysfunction (P0.01). We conclude that noncompliance with immunosuppressive medications is very common in renal transplant recipients and it results to significant acute rejection episodes and allograft failure.
