Abstract

Our objective was to study the complications of chronic renal failure (CRF) among pediatric live-donor kidney transplant recipients. Between March 1976 and December 2005, 1,785 live-donor kidney transplantations were carried out at our center. Of the recipients, 292 were 20 years old or younger (mean age 12.8 years, ranging from 4 years to 20 years). Clinical and laboratory parameters of these 292 patients were analyzed retrospectively. They were 182 boys and 110 girls. Patients who had received transplants before 1988 were treated with prednisolone and azathioprine as combined therapy. From 1988 to 1998, a triple regimen comprising prednisolone, azathioprine and cyclosporine A (CsA) was administered. Tacrolimus and mycophenolate mofetil (MMF) were introduced as primary therapy in 1998. Growth, anemia, infections, and surgical, cardiac, neurologic, bone and other medical complications were assessed. Triple-drug immunosuppression (prednisone + CsA + azathioprine) was used in 68.2% of transplants. Acute rejection rate was 47.6%; chronic rejection rate was 31%. Hypertension (62%) was the commonest complication. Anemia was diagnosed in 61%. A substantial proportion of patients (48%) were short, with height standard deviation scores (SDSs) of less than −1.88. The overall infection rate was high, and the majority (54%) was bacterial. Malignancy was diagnosed in eight (3%) patients. The incidence of urological complications was 14%, and that of vascular complications was 1%. Cardiac complications included left ventricular hypertrophy (LVH) in 47.9% of patients, left atrial enlargement (31.5%) and left ventricular dilatation and systolic dysfunction (13.7% for each). Neuropathic changes were found in 19% of our cases, with the distal muscles of lower limbs more affected. Other complications included avascular bone necrosis in 8% (all of them in the hip joint) and bone loss in 60% of patients. We concluded that, despite the long-term success of pediatric renal transplantation in a developing country, there is a risk of significant morbidity.
