title: Strategies for optimizing growth in children with kidney transplants.
abstract: Children with a well-functioning graft continue to show growth retardation even with low-dose prednisone. We have attempted to utilize the steroid-sparing effect of cyclosporine by discontinuing prednisone after graft stabilization. Since 1983, 53 children have received cyclosporine as primary immunosuppressant for renal graft maintenance. The children, aged 6 months to 18 years, received 60 transplants. One-year and four-year patient survival for cadaveric transplants was 91% and 91%, compared with 96% and 96% for living related transplants. One-year and four-year graft survivals were 82% and 65% for cadaveric transplants (n = 25), compared with 91% and 63% for living related transplants (n = 35). Of 53 patients, 23 were able to discontinue prednisone and be maintained on monodrug cyclosporine therapy, and 21 of the 53 patients had growth hormone measured using L-dopa stimulation. In patients receiving more than 5 mg of prednisone daily, growth hormone levels were lower than normal (less than 10 ng/ml). Of 15 patients who had discontinued prednisone for more than 6 months, 13 showed accelerated growth by improvement in their standard deviation scores. In 4 pubescent children with growth retardation and need for maintenance prednisone, accelerated growth occurred following growth hormone administration for 3-6 months. Based on these data we suggest that (1) discontinuation of even very small doses of prednisone may be essential for normalizing growth hormone response to L-dopa and (2) further studies are needed to exploit the growth stimulation effect of recombinant growth hormone in transplanted children.
