Plasmapheresis and paraproteinemia: cryoprotein-induced diseases, monoclonal gammopathy, Waldenström's macroglobulinemia, hyperviscosity syndrome, multiple myeloma, light chain disease, and amyloidosis

Abstract

Therapeutic plasmapheresis has been in widespread use as either a primary or adjunctive therapy in the United States since the 1960s. There are several types of plasmapheresis procedures used to treat various diseases. Plasma exchange with a centrifugal plasma separator using replacement fluid such as human albumin solution is the most widely used method in the United States. Other forms of plasmapheresis include membrane plasma separation, membrane fractionation, cryofiltration apheresis, immunoadsorption, and chemical affinity column pheresis. Therapeutic plasmapheresis has been used for the treatment of paraproteinemia to remove harmful paraproteins. Paraproteinemia is a disease classification in which abnormal or large amounts of plasma proteins such as cryoproteins or immunoglobulins are produced. In most cases, plasmapheresis is used in combination with corticosteroids and immunosuppressive drugs to prevent production of abnormal proteins or to treat the underlying disease. Cryoprotein-induced diseases, which include cryoglobulinemia, cryofibrinogenemia, and cold IgM antibody agglutinin with cryoglobulin properties, are a subclass of paraproteinemia. Other categories of paraproteinemia include monoclonal gammopathy, Waldenström's macroglobulinemia, hyperviscosity syndrome, multiple myeloma, light chain disease, and amyloidosis. Some of these diseases may be interrelated, and they may be associated with one another. In this review paper, we discuss the role of plasmapheresis in the specific classes of paraproteinemia in the United States, including our own experience.
