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.

Objectives: Hyperkalemia is an electrolyte disorder that may occur during the first few months after a renal transplant, in patients undergoing cyclosporine immunosuppression. We present our experience with cyclosporine-associated hyperkalemia in living-donor renal transplant recipients, with isolated clinically relevant hyperkalemia soon after surgery., Materials and Methods: We report 4 living-donor renal recipients with hyperkalemia soon after transplant., Results: Severe unexpected hyperkalemia (7.5- 9.4 mmol/L) was noted in our patients 12, 20, 22, and 34 days after transplant. The C2 cyclosporine concentration was within recommended range or slightly greater than 1200 ng/mL. The hypertonic glucose/insulin treatment along with potassium diet was without results. A reduction in daily cyclosporine dosages, along with 1- to 2-week administration of fludrocortisone was effective. The patients became normokalemic taking a standard, triple-drug immunosuppression protocol, and were discharged home with normal renal function. There were no repeat episodes of hyperkalemia in any of the patients during 12 months of follow-up., Conclusions: Cyclosporine should be considered a cause of hyperkalemia in renal transplant recipients. Successful treatment with fludrocortisone confirms that transitional pseudohypoaldosteronism has a potential nephrotoxic effect of cyclosporine. We recommend close monitoring of the cyclosporine concentration and administering fludrocortisone when treating hyperkalemia in renal transplant recipients.

The lack of cadaver organs for transplantation motivates some Balkan patients to go to developing countries to buy a kidney. We have followed 36 patients who received kidney transplants in Lahore and Rawalpindi, Pakistan. The patients had not been cleared for transplantation with a standard pre-transplant work-up: 80% were hepatitis-C virus (HCV) or HBsAg positive. During follow-up, seven patients died. Sixteen patients experienced wound infections with post-operative hernias, and three patients developed peri-renal hematomas. Six abscesses and four lymphoceles occurred, and four urinary fistulas were surgically treated. Nephrectomy was performed in three patients because of renal artery thrombosis. Nine patients developed active hepatitis C, and four patients manifested cytomegalovirus disease. Three patients developed steroid diabetes, and three patients experienced acute myocardial infarction. Nine patients had one or more rejection episodes. Urinary tract infection with Pseudomonas or Escherichia occurred frequently. The one-yr patient and graft survival rates were 80% and 68%, respectively. Paid unregulated renal transplantation is not recommended for both ethical reasons and because of an association with excessive morbidity and mortality., (© 2010 John Wiley & Sons A/S.)
