Background: Light chain deposition disease (LCDD) recurs frequently after renal transplantation with variable presentation.
Case report: We report the case of a 67-year-old Caucasian female with recurrence of LCDD after living-donor kidney transplantation. Bone marrow biopsy revealed kappa light chain-restricted population of plasma cells, and the patient met the criteria for multiple myeloma. Her renal function progressively worsened and she became dialysis dependent. She received 1 cycle of bortezomib along with intravenous dexamethasone. She was able to discontinue dialysis within 2 months, and at 1 year follow-up her renal function was stable.
Conclusion: Bortezomib has a role in the treatment of recurrent LCDD and multiple myeloma in kidney transplant patients. As opposed to traditional regimens, a short course may be beneficial.
