Results of kidney transplantation in 25 pediatric patients

Abstract

Outcome, long-term prognosis, growth activity and rehabilitation after kidney transplantation were studied in 25 pediatric patients transplanted with a kidney graft from one-haplotype identical parent. Excellent patient and graft survival with low incidences of acute rejection or serious complications could be achieved in this population, as compared with the results of adult recipients. Growth retardations in height and weight were observed in these patients before transplantation, and were significantly correlated with the duration of low or no kidney function. In 12 recipients who were transplanted at ages of younger than 15 years and followed up over two years, a dramatic increase in weight appeared within one year after transplantation and a greater increase in height was exhibited in the second and third year than in the first. Increase in height was significantly greater in those children transplanted at ages of younger than 10 years than in those transplanted at ages of older than 11 years. Catch-up growth was observed in one-third of these children. Retrospectively, there was no difference in the doses of prednisolone given between the two groups of patients with, and without catch-up growth, but the incidence of acute rejection was higher in the group without catch-up growth. Currently, 18 recipients have functioning grafts and 16 (88.9 per cent) of them are in full-time school or working. From these results it is concluded that kidney transplantation is the first feasible manoeuvre for those children with chronic renal failure and it should be performed as soon an possible in order to preserve their growth activity.
