1/590. IgM paraproteinemia in a patient with primary lateral sclerosis.

    Primary lateral sclerosis is an uncommon, distinct clinical entity. We report a patient with primary lateral sclerosis in whom investigations revealed an IgM monoclonal gammopathy, raised CSF protein and persistently high ESR. A number of reports suggest that lymphoproliferative disorders, paraproteinemia and clinico-pathological syndromes mimicking motor neuron diseases may be associated. We discuss the clinical features noted in our patient in relation to these reports, and the possible pathogenetic mechanisms. ( info)

2/590. Increased whole blood viscosity on cooling in a patient with cold hemoagglutinin disease.

    The whole blood and plasma viscosities have been evaluated in a patient with cold hemoagglutinin disease at different temperatures and at different shear rates. At 37 and 42 degrees C, whole blood viscosity values, regardless of the shear rate applied, resulted to be correspondent to the hematocrit value (31%). The values observed were similar to those noted in a patient with chronic bleeding anemia and an approximately equivalent hematocrit (33%). The same was true for plasma viscosity. At 32 degrees C, whole blood viscosity, regardless of the shear rate, resulted to be higher than expected. The values observed were similar to those noted in a normal subject with a clearly higher hematocrit value (44%) and definitely higher than those noted in the chronic anemia patient. On the contrary, plasma viscosity remained unchanged. These studies indicate that in cold hemoagglutinin disease, red cell aggregation and piling are capable of increasing blood viscosity. ( info)

3/590. poems syndrome, steroid-dependent diabetes mellitus, erythema elevatum diutinum, and rheumatoid arthritis as extramedullary manifestations of plasma cell dyscrasia.

    poems syndrome is a rare synopsis of different multisystemic disorders (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammapathy, and skin lesions) associated with plasma cell dyscrasia. We herein report the atypical case of a 44-year-old white man presenting with glomerulopathy, poems syndrome, and erythema elevatum diutinum with a few-year history of non-insulin-dependent diabetes mellitus (NIDDM) and seronegative rheumatoid arthritis (RA) as early manifestations of IgAlambda multiple myeloma. The prescription of 1 mg/kg/day prednisone improved the patient's features dramatically. skin lesions improved by the association of glucocorticoids and plasma exchange, recurred when plasmapheresis ceased, and remitted when plasma exchange was reintroduced. NIDDM requiring insulinotherapy recurred when corticoids were discontinued and remitted when prednisone was reintroduced. However, prednisone and plasmapheresis had no effect on polyneuropathy, M-paraprotein, and plasma cell dyscrasia in our patient, who developed indolent multiple myeloma a few years later. We thus concluded that poems syndrome, steroid-dependent diabetes mellitus, rheumatoid arthritis, RA, and skin vasculitis in our patient were triggered by plasma cell dyscrasia. ( info)

4/590. Paraproteinemic variety of pure red cell aplasia: immunological studies in 1 patient.

    A case of adult pure red cell aplasia (PRCA) with a serum IgG inhibitor to erythropoiesis and an IgG lambda M component is presented. The study of lymphocyte populations revealed a slight but definite decrease of E and EA rosettes, with dissociation between E rosettes and PHA blastic transformation of blood lymphocytes and increase of membrane IgM-bearing lymphocytes. The relationship between PRCA and paraproteinemia is discussed: it is suggested that the serum M component may derive from an immunological unbalance between T and B lymphocytes. Since a survey of the literature reveals 5 similar cases, it is suggested that paraproteinemia may be the hallmark of a particular variety of chronic PRCA 'type 1'. ( info)

5/590. Chronic granulocytic leukemia, neutrophilic type, with paraproteinemia (IgA type K).

    A patient with chronic granulocytic leukemia, neutrophilic type, was followed for 28 months. A paraproteinemia, IgA type K, and Bence Jones proteinuria (K) appeared without prior chemotherapy with alkylating agents. ( info)

6/590. Cryopathic gangrene with an IgM lambda cryoprecipitating cold agglutinin.

    Immunochemical and serologic studies of cold agglutinis in patients with chronic cold agglutinin disease (CCAD) have shown the almost exclusive occurrence of IgM kappa antibodies with specificity for the I antigen of red cells. An unusual subgroup of patients has been delineated in which the cryoprotein is IgM lambda, frequently lacks I specificity and often cryoprecipitates. Studies of such a protein from a patient with an unusual array of immunoproliferative disorders including Grave's disease with exophthalmos and Waldenstrom's macroglobulinemia indicate that the cryoprecipitating and cold agglutinating properties probably derive from the sam protein. The occurrence of this type of antibody should suggest the presence of a more aggressive lymphoproliferative disorder than simple CCAD. ( info)

7/590. monoclonal gammopathy of undetermined significance.

    monoclonal gammopathy of undetermined significance is not a benign condition. There is a significant increase in mortality associated with the risk of development of multiple myeloma and related disorders. ( info)

8/590. autoimmunity and extranodal lymphocytic infiltrates in lymphoproliferative disorders.

    OBJECTIVE: To examine the relationship between autoimmunity and extranodal lymphocytic infiltrates in different lymphoproliferative disorders with immunoglobulin alterations. SUBJECTS AND DESIGN: A clinical review combined with a retrospective cohort study of 380 patients, 28 with monoclonal gammopathy of undetermined significance, three with common variable immunodeficiency, 147 with chronic lymphocytic leukaemia, 57 with Waldenstrom's macroglobulinaemia and 145 with non-Hodgkin's malignant lymphoma. SETTING: A university hospital and The State serum Institute in Copenhagen. INTERVENTION: Clinical examination of each patient with special attention to chronic inflammatory and autoimmune manifestations. Biopsies were taken from non-infectious infiltrates, some of which were additionally tested with PCR analysis for gene rearrangements. Serological screening with a test battery for various autoantibodies was used in combination with techniques for the detection of M-components and monoclonal B-cell proliferation. MAIN OUTCOME MEASURES: Clinical and/or serological autoimmune manifestations, M-component and other immunoglobulin alterations, and inflammatory tissue changes were studied in patients with chronic inflammatory, polyclonal or oligoclonal pseudolymphomas and in monoclonal, malignant extranodal lymphomas. RESULTS: In 380 consecutive patients, 49 (12.9%) had extranodal manifestations, of whom 47 also had autoimmune manifestations. Nearly half of the 47 patients had more than one autoimmune manifestation. There was a strong correlation between clinical signs and corresponding autoantibodies such as anti-SSA and -SSB antibodies in sjogren's syndrome (10 cases), antithyroid peroxidase antibodies in thyroiditis and Graves' disease (10 cases), and parietal cell antibodies in gastric ulcers with maltoma (12 cases). Clinical and serological signs of autoimmunity correlated strongly with female sex (34, 72% women; and 13, 28% men) and with immunoglobulin alterations. CONCLUSIONS: To our knowledge this is the first systematic review of B-lymphoproliferative and autoimmune disorders indicating that pseudolymphoma and malignant lymphomas, including maltomas, may develop in the context of a permanent autoantigenic drive.

9/590. Successful treatment of IgM paraproteinaemic neuropathy with fludarabine.

    OBJECTIVES: To evaluate the response of four patients with IgM paraproteinaemic neuropathy to a novel therapy-pulsed intravenous fludarabine. BACKGROUND: The peripheral neuropathy associated with IgM paraproteinaemia usually runs a chronic, slowly progressive course which may eventually cause severe disability. Treatment with conventional immunosuppressive regimens has been unsatisfactory. Fludarabine is a novel purine analogue which has recently been shown to be effective in low grade lymphoid malignancies. methods: Four patients were treated with IgM paraproteinaemic neuropathy with intravenous pulses of fludarabine. Two of the four patients had antibodies to MAG and characteristic widely spaced myelin on nerve biopsy and a third had characteristic widely spaced myelin only. The fourth had an endoneurial lymphocytic infiltrate on nerve biopsy and a diagnosis of Waldenstrom's macroglobulinaemia. RESULTS: In all cases subjective and objective clinical improvement occurred associated with a significant fall in the IgM paraprotein concentration in three cases. Neurophysiological parameters improved in the three patients examined. The treatment was well tolerated. All patients developed mild, reversible lymphopenia and 50% mild generalised myelosuppression, but there were no febrile episodes. CONCLUSION: Fludarabine should be considered as a possible treatment for patients with IgM MGUS paraproteinaemic neuropathy. ( info)

10/590. November 1998--70 year old woman with SLE, paraproteinemia and polyneuropathy.

    A 70 year old woman developed a sensory-motor polyneuropathy 12 years after almost continuous treatment with hydrochloroquine for SLE. sural nerve biopsy disclosed abundant lipid inclusions in schwann cells and vessels against a background of axonal degeneration. After cessation of therapy the patient improved moderately. This case underscores the usefulness of nerve biopsy in the study of management of patients with peripheral neuropathy associated with systemic illnesses. ( info)
