Monoclonal Gammopathy of Renal Significance (MGRS) is a group of heterogeneous disorders characterized by renal dysfunction secondary to the production of a monoclonal immunoglobulin by a nonmalignant B cell or plasma cell clone. We report the clinical and histological outcomes of two patients with biopsy-proven MGRS: one patient showed membranoproliferative glomerulonephritis with monoclonal k-light chain and C3 deposits, the second patient showed immunotactoid glomerulopathy. Both patients were treated with a 9-month chemotherapy protocol including bortezomib, cyclophosphamide, and dexamethasone. Renal biospy was repeated after 1 year. The estimated glomerular filtration rate (eGFR) increased from 22.5 (baseline) to 40 ml/min per 1.73 m2 after 12 months, then to 51.5 ml/min per 1.73 m2 after 24 months; proteinuria decreased from 4.85 (baseline) to 0.17 g/day after 12 months, then to 0.14 g/day after 24 months. Repeat renal biopsies showed a dramatic improvement of the glomerular proliferative lesions and near complete disappearance of the immune deposits. A bortezomib-based treatment proved very effective and was well-tolerated in the two patients presenting with clinically and histologically aggressive MGRS.

Multiple Myeloma (MM) is a hematological malignancy characterized by clonal plasma cell in bone marrow that produceabnormal globulin, which resulted in monoclonal gammopathy. Multiple Myeloma Non-Secretory (MMNS) is a very rareform of multiple myeloma with monoclonal plasmocytic proliferation in bone marrow supported by clinical manifestationand radiological findings. However, plasma cells fail to secrete immunoglobulin. A 44-year-old female came to SardjitoGeneral Hospital with main complaints of weakness and back pain. General weakness and pale palpebral conjunctiva were6 observed (+/+), liver and spleen were not palpable. Blood test results were as follows: Hb 3.0 g/dL, RBC 1.07 x 10 / μL, WBC3 3 562 x 10 /μL, PLT 114 x 10 /μL, A/G ratio 1.07, BUN 51.5 mg/dL, creatinine 4.62 mg/dL, and calcium 3.1 mmol/L. Skeletalsurvey suggested a multiple osteolytic. Protein electrophoresis revealed hypogammaglobulinemia with no M-spike. Therewere 66% of plasma cells in bone marrow. Patient was diagnosed by MMNS. Diagnosis MMNS can be established if clonalplasmacytes is accompanied with renal insufficiency and hypercalcemia. However, monoclonal gammopathy was not foundin serum protein electrophoresis. A case reported of 44-year-old female diagnosed as MMNS with 'punched out' multipleosteolytic, increased plasma cells in bone marrow without evidence of paraprotein in circulation proved by low A/G ratio andnegative M-spike.

Abstract The association of Hodgkin disease with monoclonal gammopathy has rarely been reported. We present a case of a 48-year-old woman with a history of autoimmune hemolytic anemia and Graves disease who presented with hepatosplenomegaly and a γ-heavy-chain paraprotein. Histopathology of lymph node and bone marrow revealed nodular lymphocyte-predominance Hodgkin disease, while examination of the spleen revealed plasmacytosis consistent with γ-heavy-chain disease. Following splenectomy, the patient has remained in complete remission for both conditions with no further treatment. To our knowledge, this is the first report of a patient with both γ-heavy-chain disease and nodular lymphocyte-predominance Hodgkin disease. Given recent data indicating the B-cell nature of this form of Hodgkin disease, the authors propose that in this unique case there may be a clonal relationship between these 2 concurrent B-cell lymphoproliferative processes.
