Abstract

In adult liver transplant recipiens, 2-h post-Neoral (C2) dose monitoring is associated with a lower incidence and severity of acute cellular rejection and improved renal function than CO (trough level) monitoring. This study examined whether switching from CO to C2 monitoring during maintenance also improves renal function in pediatric liver transplant recipients. Three boys aged 11-16 yr with stable graft function at 6-50 months after liver transplantation were switched from CO to C2 monitoring. Median CO was 148 ng/mL (range 100-186), and median C2 was 767 ng/mL (range 702-1187). At the time of conversion, C2 levels exceeded the recommended targets (0-6 months 1000 ng/mL; > 12 months 600 ng/mL in all children). Within 3 months, serum creatinine level decreased by a median of 42.8%, and glomerular filtration rate increased by a median of 86%. No clinical or biochemical evidence of rejection was noted during the 6-month follow-up. Our results suggest that in pediatric liver transplant recipients, C2 monitoring is associated with greater improvement in renal function than CO monitoring; switching to C2 monitoring can correct cyclosporine-associated toxicity.
