  • Title: [Clinical aspects of monoclonal gammopathies in diseases of the lympho-plasmacytic cell system].
    Author: Westerhausen M.
    Journal: Acta Med Austriaca; 1982; 9(4):143-9. PubMed ID: 6814157.
    Abstract:
    Paraproteinemias can be subdivided in 1. obligatory paraproteinemias (myeloma, macroglobulinemia, heavy chain diseases); 2. accompanying paraproteinemias (Non-Hodgkin's lymphomas, myeloproliferative diseases, immune deficiency diseases, autoimmune diseases, transitory paraproteinemias after infection, paraproteinemias in association with nonlymphatic neoplasms); 3. benign paraproteinemias: a) with symptoms (primary amyloidosis, chronic cold agglutinin disease, paraproteinemias with further autoantibody function, monoclonal cryoglobulinemia); b) asymptomatic forms. Myeloma is the most common type of obligatory paraproteinemias. Characteristic findings are: Paraproteinemia and/or paraproteinuria in 98%, increase of plasma cells in the bone marrow in 84%, alterations in the roentgenograms of the skeleton in 79%. Clinical staging is of importance for the prognosis (amount of paraproteins, Hb level, renal disease, hypercalcemia, lytic lesions of bone). Neurologic complications, hemostasis dysfunction, cryopathies may be other symptoms. The terminal phase of the disease is determined by plasma cell proliferation, immune deficiency and renal disease or myelomonocytic leukemia. As to Non-Hodgkin's lymphomas the accompanying paraproteinemia is to be found in immunocytomas and in CLL. At last it has to be mentioned that B-cell disorders will influence the T-cell populations and vice versa.
