Abstract

BACKGROUND:

Primary focal segmental glomerular sclerosis (FSGS) recurs in 20 - 40% of patients after kidney transplantation. Rituximab has been used to treat several glomerular diseases.

PATIENTS AND RESULTS:

We treated two renal-transplant patients with recurrence of FSGS with rituximab. Despite a prophylactic perioperative therapy of plasmapheresis (PE) and i.v. cyclosporine A, Patient 1 developed significant proteinuria, at 1 day after his first kidney transplantation. After two infusions of rituximab (375 mg/m2) he had complete remission. A second relapse, which occurred on Day 40, was also successfully treated by PE and one additional infusion of rituximab. 10 months after transplantation, he still has complete remission from recurrent nephrotic syndrome. Patient 2 also developed significant proteinuria, but 1 day after a second kidney transplantation. Nephrotic syndrome persisted despite 27 sessions of PE and cyclophosphamide therapy. At 13 months after transplantation, he received four infusions of rituximab (375 mg/m(2)), but this was ineffective.

CONCLUSION:

There is a need to demonstrate whether or not rituximab therapy is of interest to prevent and to treat nephritic syndrome in renal-transplant patients who suffer from FSGS.
