Abstract
To evaluate the efficacy of renal transplan- tation in small pediatric patients, we have reviewed 41 allografts performed in 39 children (28 M/11 F) less than 6 years of age between 1987 and 1998 in the North Italy Transplant Program. Of these patients, 39 had a cadaver donor and 2 a living-related donor, with ages ranging from 20 days to 35 years. The mean follow-up was 56 months. Graft survival was 74.5% and 70.5% at 1 and 5 years, respectively. The causes of graft lost were acute rejection (4), graft vascular thrombosis (4), and hemolytic uremic syndrome recurrence (1). Only 1 patient has died due to chickenpox. Double and triple immunosuppressive therapies were used in 63% and 37% of patients, respectively, on the basis of different center protocols, without differences in graft survival. Steroids were successfully administered on alternate days in 37% of patients, 6–12 months after transplantation. Thrombosis was reported in 2 of 6 kidneys from donors less than 1 year of age and in 2 of 35 donors older than 1 year (P<0.05). Thirty rejections occurred in 23 patients: 7 episodes were steroid resistant and were treated with ATG/OKT3. Thirty-four infections were reported in 16 of 41 patients; of these 17 were viral, 14 bacterial, and 3 due to Mycoplasma. Four surgical complications were reported: 1 graft artery stenosis, 1 ureteral stenosis, 1 urinary leak, and 1 lymphocele. Mean height standard deviation score improved from –2.0±1.3 pre transplantation to –1.8±1.4, –1.5±1.3, and –1.5±1.5 at 1, 2, and 5 years post transplantation. Linear growth was significantly better in infants treated with alternate-day steroids. Hypertension was a frequent complication, since 19 of the 30 patients with a 5-year follow-up were still being treated with antihypertensive drugs. In conclusion, graft survival in patients less than 6 years old is satisfactory and similar to that obtained in children aged from 6 to 18 years (70.5% vs. 78.9% at 5 years, P=NS). Consequently, since there are many difficulties in managing infants on maintenance dialysis, an early transplant should be considered. Donors older than 24 months carry a low risk of vascular thrombosis and may be successfully grafted in infants.
