P1695OUTCOMES OF KIDNEY TRANSPLANTATION IN RECIPIENTS WITH MENTAL RETARDATION

Abstract Background and Aims Mental retardation in patients with chronic kidney disease is a relative contraindication for kidney transplantation. Currently, in the literature there are limited outcome data in renal transplant recipients with mental retardation and approaches to decision of transplantation changes in different centers. The aim of this study is to evaluate the results of kidney transplantation recipients with mental retardation in our center. Method In this study, we examined retrospectively 8 kidney transplant recipients with mental retardation in Renal Transplantation Unit of Ankara University School of Medicine between 2006-2018 years. Results The cause of mental retardation in these patients were; genetic syndromes in three patients, meningoencephalitis in one patient, prematurity in one patient, and chromosomal abnormality in one patient. In two patients, the cause of mental retardation is unknown. All patients had good social support for drug compliance and follow-up. The causes of end-stage renal failure were; cystic kidney disease in three patients, hypertensive nephropathy in one patient and vesicoureteral reflux in one patient. In three patients, the etiology of kidney disease is unknown. At the time of pretransplantation period evaluation, six candidates were receiving hemodialysis and two candidates were receiving peritoneal dialysis respectively. Mean dialysis duration before transplantation was 50.7±22.8 months (min 4-max 180). Cadaveric kidney transplantation was performed in three of eight patients (deceased donor kidney allocated to patient with medical urgency in the event of potential imminent loss of dialysis access in one patient and in normal conditions in two patients) and living kidney transplantation was performed in five patients. The mean follow-up period after transplantation was 54.1±48.0 months. Three patients had early posttransplant complications; including urinary tract infection in three patients, deep vein trombosis in one patient and cardiopulmoner arrest with septic shock secondary to femoral graft infection and parailiac abscess in one patient (Table). No patients underwent graft biopsy and no patients experienced acute rejection episode. At the end of the follow-up time, graft and patient survival were 100%. Conclusion Mental retardation is not a contraindication for kidney transplantation in candidates without the history of noncompliance with proper social support.
