Abstract
Indications, results, techniques, laboratory monitoring and complications of therapeutic plasmapheresis in patients with symptomatic paraproteinemia are reviewed. In paraproteinemia associated with severe complications plasma-pheresis has been used successfully as an emergency treatment, as a treatment that reduces temporarily the paraprotein level until reduction of resynthesis is reached by cytotoxic therapy, or as a longterm adjuvant therapy in cases of slowly proliferating plasmacytoma or lymphoma. Plasmapheresis has not been shown to influence the underlying malignant process. Paraprotein-related complications that can be reduced by plasmapheresis are hyperviscosity, hypervolemia, haemorrhagic diathesis, cryoglobulinemic symptoms, rapidly deteriorating renal insufficiency, visual impairment, and neurologic disturbances. Technically, large-pored plasma filters have some advantage as compared to centrifugation techniques. Paraprotein-specific complications of therapeutic plasmapheresis are rare. As an ancillary treatment, therapeutic plasmapheresis has expanded the therapeutic tools in the management of paraproteinemia.
