Abstract

End-stage kidney disease may develop in 1% to 3% of cyclosporine-treated heart transplant recipients, and most patients show a decreased glomerular filtration rate. There are little data on kidney function in pediatric recipients, although good function is needed for their optimal development. Kidney function was prospectively investigated in 10 children receiving triple immunosuppression (cyclosporine, azathioprine, methylprednisolone) during the first 18 months after heart transplantation. The early cyclosporine trough level target was 300 to 500 micrograms/L and 100 to 200 micrograms/L after the first year. 51Chromium-ethylenediamine tetraacetic acid, para-amino hippuric acid, lithium, and sodium clearances, measurements of serum and urinary electrolytes, and urinary concentration tests were performed. Renal biopsy specimens were obtained from four patients after 18 months. Heart function was good in all patients. Six patients (60%) remained rejection-free at 18 months. The mean glomerular filtration rate was 92.4 ml/min/1.73 m2 before transplantation, increased to 115 by 6 months (p < 0.05), and thereafter remained stable. The mean renal plasma flow was 487 ml/min/1.73 m2 after 18 months. Hypertension was seen in all patien...Continue Reading
