Could living unrelated renal transplantation ameliorate the actual shortage of organs in the Balkan region?

BACKGROUND

Despite the efforts for more transplants performed with organs from deceased donors, the living renal transplantation is still the predominant transplant activity in the Balkan region. In order to adress the severe organ shortage, we started accepting unrelated (emotionally related) living donors (LURD). Here we present our 10-year experience with living unrelated renal transplantation (LURT).

METHODS

Twenty four LURT were performed in our center in the last 10 years. The mean recipients and donors age was 41.7 and 47.2 years, respectively. As LURD spouses (n=17) and extended family members (n=7) were accepted predominantly. All donors went through careful psychological evaluation in order to confirm emotional relationship. The final decision was taken after both the recipient and the donor signed a consent in front of a judge. A quadruple sequential immunosuppressive protocol was used in all recipients. The 5-year Kaplan Meier graft survival rate, HLA mismatch, rejection episodes, delayed graft function, serum creatinine and Glomerular filtration rate-Modification of the diet in renal disease (GFR-MDRD) were analyzed. The results were compared with 30 living related renal transplants (LRT) performed during the same time with mean recipients and donors age of 35.9 and 58.5 years, respectively.

RESULTS

The mean follow up for LURT and LRT recipients were 81.4 and 79.6 months, respectively. There was a significant difference regarding recipients and donors age, HLA mismatch (5.07 and 2.9) and rejection episodes (16% vs. 11%) in LURT and LRT recipients. The 5 years graft survival rate was excellent in both groups (83 and 81%, respectively). There was no significant difference in 5 years serum creatinine (129.3 vs 121.1 μmol/lit) and 5 years GFR-MDRD (56.6 and 58.6 ml/min).

CONCLUSION

The authors present an excellent 5-year graft survival rate in both LURT and LRT recipients. Therefore, LURT could ameliorate the severe organ shortage in the region and could be recommended as a valuable source of organs in the countries with developed and underdeveloped deceased donor donation.
