【 摘 要 】

A 63-year-old woman presented with progressive renal insufficiency, until a glomerular filtration rate (GFR) of 12 mL/min. A renal biopsy demonstrated glomerular deposition of immunoglobulin k light chain. The presence of a small population of monoclonal plasmacytes producing an only light k monoclonal component was demonstrated and Bortezomib and Dexamethasone (BD) was provided as initial therapy. After seven courses of therapy, renal function improved without dialysis requirements up to a GFR 31 mL/min. Under hematological complete response (HCR) the patient underwent high dose of melphalan (HDM) and autologous peripheral blood stem cell transplant. Fifty-four months later the patient remains in HCR and the GFR has progressively improved up to 48 mL/min. This report describes a notably renal function improvement in a patient with Light Chain Deposition Disease after therapy with BD followed by HDM, which can support this treatment as a future option for these patients.
