title: 300 pediatric renal transplantations: A single-center experience.
abstract: Our objective was to relate the results of 300 consecutive kidney transplants performed in children at a single center.
  
  
  METHODS
  An analysis of kidney transplants was performed on patients less than 18 years old engrafted from May 1977 to August 2005.
  
  
  RESULTS
  Among 300 kidney transplants, 48% of the patients were female, 87% were Caucasian, and 13% were African-Brazilian. The mean age at transplant was 11.5 +/- 4.5 years with 39 (13%) less than 6 years of age. The most frequent etiology of renal failure was vesicoureteral reflux/obstructive uropathy (36%) followed by glomerulopathy (27%). The donor was deceased in 32.3% and living related in 77.7% (parents 82%). The mean posttransplant follow-up was 4.8 +/- 4.3 years. The initial immunosuppression was CyA + AZA + PRED in 45%; CyA + MMF + PRED in 9.6%; TAC + AZA + PRED in 7.3%; TAC + MF + PRED in 9.7%; or TAC + MF without PRED in 10%. Sirolimus was employed initially in three cases. Induction with OKT3/ATG occurred in three patients and 112 received an anti-IL2 receptor antibody. The 103 graft losses during 28 years of follow-up were secondary to chronic allograft nephropathy in 51 (49.5%), vascular thrombosis in 5 (4.8%), acute rejection in 12 (11.6%), and recurrence of original disease in 13 (12.6%). Sixteen (15.5%) died with functioning grafts. Graft survival in the first, fifth, and tenth year were 90%, 72%, and 59%, respectively. Patient survival in the first, fifth, and tenth years were 95%, 93%, and 85%, respectively, with infection as the main cause of death.
