Bortezomib therapy for nephrotic syndrome due to idiopathic membranous nephropathy.
Overview
abstract
Idiopathic membranous nephropathy is a common cause of nephrotic syndrome in adults. The nephrotic syndrome due to idiopathic membranous nephropathy is often resistant to glucocorticosteroids and requires an alkylating agent such as chlorambucil or cyclophosphamide to induce remission. Recent studies illustrate that antibodies against the autoantigen M-type phospholipase A2 receptor contribute to a vast majority but not all cases of idiopathic membranous nephropathy. Herein, we report a patient with nephrotic syndrome due to membranous nephropathy that was resistant to 6 months of therapy with ramipril and high-dose glucocorticosteroids but responded to a single cycle of bortezomib infusion.
