Abstract
Even if kidney graft survival has improved during the last decades, sensitized pediatric patients are an emerging problem. We describe a 17-yr-old male who lost his first graft due to chronic rejection becoming hyperimmunized (CDC PRA 99.61%). A desensitization protocol based on high-dose IVIG, PP, and two Mabthera(®) infusions was performed with minor response (CDC PRA post-desensitization 80%). One month after his second non-living transplant, he developed a biopsy-proven AMR; post-transplant immunological monitoring showed the presence of donor-specific anti-DQ5 antibodies (DSA, MFI 20.000). He received methylprednisolone pulses and 45 PP sessions without clinical response; eculizumab was then used to salvage a kidney undergoing severe PP-resistant rejection. A biopsy performed after the fourth eculizumab infusion showed complete resolution of AMR. Eculizumab infusions were then continued for the first year post-transplantation. Two yr after transplantation, graft function is stable. Anti-C5 therapy may represent an effective therapeutic option in pediatric patients with PP-resistant AMR.
