Short-term outcomes of Thymoglobulin induction in pediatric renal transplant recipients

No data are currently available that describe the clinical outcomes associated with Thymoglobulin (rabbit polyclonal anti-thymocyte globulin) induction in pediatric renal transplant recipients. We report the outcomes of 17 pediatric renal transplant recipients (mean age 10.1+/-5.2 years) transplanted between 1 August 1999 and 31 July 2001. Eleven patients (65%) were Caucasian and 6 (35%) were African-American. Eleven (65%) recipients received cadaveric allografts. Two patients (12%) were second allograft recipients. One patient had primary allograft non-function secondary to vascular thrombosis. Two patients (12%) had delayed allograft function. Immunosuppression consisted of Thymoglobulin induction (mean number of doses 6 1.7) with tacrolimus (62%) or cyclosporine A (38%), mycophenolate mofetil, and prednisone. One year post transplant, patient and graft survival was 100% and 93%, respectively. No acute rejection episodes occurred during the first 6 months after transplantation in any of the recipients. Additionally, no rejection episode occurred among the 14 patients followed for 1 year after transplant. The incidences of asymptomatic cytomegalovirus (CMV) and Epstein-Barr virus (EBV) seroconversion at 1 year in seronegative recipients with a seropositive donor were 100% of 4 patients and 100% of 4 patients, respectively. No symptomatic CMV or EBV infections and no post-transplant lymphoproliferative disease have occurred in any patient. These short-term data suggest that Thymogobulin induction is safe and effective in combination with triple immunosuppressive therapy for preventing early rejection in pediatric renal transplant recipients.
