[Renal disease in multiple myeloma]

Abstract

Renal involvement is common in multiple myeloma. Although several types of renal disease are observed, most of them are considered to be specifically related to monoclonal immunoglobulin light chains. Myeloma cast nephropathy is the most frequent and sometimes associated with acute renal failure. AL amyloidosis and monoclonal immunoglobulin deposit disease are often presented as a nephrotic syndrome. In this review, we describe the pathogenesis and diagnosis of these three renal diseases. We also focus on the treatment of renal disease in multiple myeloma, in the view points of the chemotherapy to reduce M-protein and the prevention to reduce the risks of promoting renal injury.
