Repeated Administrations of Rituximab along with Steroids and Immunosuppressive Agents in Refractory Steroid-resistant Nephrotic Syndrome

摘要

A recent randomized control trial in children with steroid-resistant nephrotic syndrome revealed that two doses of rituximab did not reduce proteinuria. Case characteristics: A 14-month-old boy developed refractory steroid-resistant nephrotic syndrome due to focal segmental glomerulosclerosis. Observation: The patient achieved complete remission 11 months after disease onset following eight doses of rituximab combined with steroids and cyclosporine. Message: Long-lasting B cell depletion with repeated rituximab administrations may be required to achieve complete remission in patients with steroid-resistant nephrotic syndrome and massive proteinuria.
