[Renal transplantation in children under five years of age. Experience at the Hopital des Enfants-Malades].
From 1976 through 1991, 50 renal transplants (with 7 kidneys from living related donors and 43 cadaver kidneys) were performed in 47 children under five years of age (range 11 to 59 months) at the Enfants-Malades Hospital, Paris, France. Donor age ranged from 3 months to 53 years. Six of the seven kidneys from living related donors are currently functioning after a follow-up of 6 months to 8 years, whereas actuarial survival of cadaver kidneys was 70% at one year and 66% at five years. The main cause of graft loss was vascular thrombosis (40% of lost kidneys). In the most recent years of the study period, graft survival was substantially improved by routine prophylactic anticoagulant therapy with low-molecular weight heparin: one-year graft survival rate was 83% in the 23 children grafted between 1989 and 1991. Posttransplantation growth was closely related to quality of graft function: among the 29 children with sufficiently long follow-up the 19 patients with normal renal function exhibited normal or catch-up growth, whereas the ten patients with chronic renal failure or recent rejection had poor growth. Complications were uncommon with the exception of hypertension. Mortality rate was 12%, i.e., only slightly higher than in older pediatric kidney recipients. Achievement at school was normal in most cases (with a lag in only five patients). Provided effective therapy is given to prevent the main adverse outcome (i.e., vascular thrombosis), renal transplantation does not involve excessive risks even in infants as young as one year of age.
