An analytical review of growth hormone studies in children after renal transplantation.

With steady improvement in 1- and 5-year patient and graft survivals in the last decade, rehabilitation of the child is the major focus of the transplant physician. The notion that the elimination of the uremic milieu should enable children to grow has not been born out over time, and growth retardation continues to be a serious morbidity in many children despite a well-functioning renal allograft. In children with chronic renal failure prior to renal transplantation, recombinant human growth hormone (rhGH) has been recently shown in controlled trials to improve growth. The use of rhGH in children after renal transplantation is controversial, since uncontrolled studies have questioned its safety. Acute rejection and graft loss have been reported in children after the initiation of rhGH. This study analyzes the data regarding the safety and efficacy of rhGH in children after renal transplantation as presented in seven current published reports. The demographic characteristics of the patients, the dose and duration of rhGH therapy, the "growth" rates of the patients before and after rhGH therapy, renal function before and after rhGH therapy, and other possible complications are reviewed. Based on this analysis, suggestions for future studies are made.
