Abstract: | Data on the use of enteric-coated mycophenolic acid (EC-MPS) in pediatric transplantation cases are scarce. We undertook a 12-month, multicenter, open-label pilot study in which 16 de novo renal transplant patients aged 5–16 years received EC-MPS with cyclosporine A microemulsion (CsA-ME), steroids, and anti-interleukin-2 receptor antibody induction. The mean dose of EC-MPS was 916 ± 93 mg/m2 per day during weeks 1–2, 810 ± 193 mg/m2 per day during months 3–6, and 827 ± 153 mg/m2 per day during months 6–12. The mean CsA C2 level exceeded target range up to month 6 post-transplant. Efficacy failure (biopsy-proven acute rejection, graft loss, death or loss to follow-up) occurred in two patients: one patient with primary non-function underwent nephrectomy, and one patient experienced biopsy-proven acute rejection (Grade 1B, day 344) following EC-MPS dose reduction. There were no deaths. Creatinine clearance (Schwartz) was 103 ± 30 mL/min per 1.73 m2 at month 6 and 100 ± 16 mL/min per 1.73 m2 at month 12. The majority of adverse events were mild or moderate (101/126, 80.2%). In this pilot study, EC-MPS 450 mg/m2 administered twice daily with CsA, steroids, and interleukin-2 antibody induction resulted in a low rate of rejection with good renal function in a pediatric population. However, a larger, controlled trial is required to confirm these results. |
