Several factors influencing post-transplant growth were analysed in a total of 163 children receiving transplants at the Medical School Hannover. Statural height at the time of transplantation depended on the length of the pre-transplant period of chronic renal failure, and was more retarded in children with congenital renal diseases than in those with acquired diseases. The retardation of bone age correlated significantly with the degree of growth retardation. The immunosuppressive regimen of cyclosporine A (CyA) and low-dose prednisolone was followed by significantly better growth rates than azathioprine (Aza) plus high-dose prednisolone. In 22 prepubertal children receiving CyA, poor graft function with a glomerular filtration rate below 40 ml/min per 1.73 m2 inhibited catch-up growth. The final height of 20 grown-up transplant recipients was found to be in the lower range of normal. A comparison of conventional and CyA treatment showed that adult height in the CyA group was higher than in the Aza group due to a significantly higher growth velocity.
SUMMARY One hundred and thirteen children (59 boys and 54 girls aged from 2 to 16 years) with end stage renal failure entered the renal dialysis and transplantation programme between 1972 and 1983. They were followed up until December 1985. Ninety eight children were initially treated by haemodialysis in hospital and 15 by renal transplantation. The average wait on dialysis was seven months (range 0-1-43 months). One hundred and six children were given 129 renal transplants, 32 of which were from living related donors.At the end of 1985 94 of the 113 patients (83%) were alive, 81 (72%) with functioning grafts, 11 (10%) were receiving haemodialysis in hospital, two (1%) were being treated by continuous ambulatory peritoneal dialysis, and three had been lost to follow up. The 14 years actuarial survival was 81%. Four patients receiving dialysis and 12 who had received transplants died, a mortality of 14%. The main complications of treatment were retardation of growth in 49 (43%), hypertension in 75 (66%), and osteopathy in 36 (32%). Retardation of growth could not be reversed by successful renal transplantation. Seventy two patients (88%) assessed their health as good to excellent, and 9 (12%) as poor. Patients with a functioning graft did much better than those receiving dialysis. Treatment of end stage renal failure led to full rehabilitation in most patients, and renal transplantation was more effective than dialysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
