Long term complications following renal transplantation.

The long term complications of renal transplantation were assessed in 36 patients who had lived for 10 or more years with a functioning renal transplant. Thirty-three patients were alive with a mean plasma creatinine of 0.13 mmol/L (SD 0.07). A 62 year old women died from a myocardial infarction 11 years after transplantation and two women developed chronic rejection and returned to dialysis after 17 years. Nineteen patients have required antihypertensive therapy, five have suffered ischaemic heart disease and two a cerebrovascular event. Malignancy has developed in 13 patients, with four having two or more organs involved. Skin cancers (9 squamous cell, 4 basal cell) were present in all 13 patients and recurred in six. The other malignancies included carcinoma of cervix (2), cervix and bladder (1) and thyroid (1). Three patients have required parathyroidectomy for autonomous hyperparathyroidism, two splenectomy for hypersplenism, and one bilateral hip replacement for avascular necrosis of the femoral heads. The development of hypertension, vascular disease and malignancy are the most important long term complications after renal transplantation. Strategies must be formulated to reduce the morbidity and mortality from these causes.
