OBJECTIVE: Limited data exist on gender-specific aspects in hematologic malignancies and have been obtained mostly in non-Hodgkin lymphomas. The objective of this study was to investigate gender-specific aspects in patients with multiple myeloma (MM) undergoing autologous stem cell transplantation (ASCT). METHODS: A retrospective data analysis of 191 patients with MM who underwent ASCT was performed. Data collected from clinical records included age, sex, stage, induction therapy, outcome of induction, kind of stem cell mobilization, response to induction therapy and ASCT, cytogenetic aberrations, progression-free survival, and overall survival...

Paraproteins can cause a variable set of pathologic changes in the kidney. The introduction of novel anti-plasma cell agents capable of reversing renal failure have revolutionized the management of paraprotein-mediated kidney injury. Activation of the transcription factor nuclear factor kB (NF-kB) has been shown to be involved in the development of human glomerulonephritis (GN). Inhibitors of NF-kB may provide potential agents for treatment of immune complex GN. In this paper, we report a patient with IgA nephropathy and IgG kappa myeloma, who responded dramatically to chemotherapy targeted toward myeloma...

BACKGROUND Whether creatine-kinase (CK) is elevated or not in chronic inflammatory demyelinating polyneuropathy (CIDP) and its variants is not comprehensively investigated. CASE REPORT We report the case of a 47-year-old male who developed weakness of the left lower leg and the right index finger at age 42 years. At age 44 years, paresthesias and dysesthesias of both lower legs and mild right lower leg weakness additionally developed. CK was recurrently elevated since age 42 years but paraprotein and anti-myelin-associated glycoprotein (MAG)-antibodies were negative...

BACKGROUND: Multiple myeloma (MM) is a complex heterogeneous disease. Various risk stratification models have been recommended including cytogenetic and FISH analysis to identify high-risk patients who may benefit from novel treatments, but such facilities are not widely available. The International Scoring System (ISS) using beta-2-microglobulin and albumin remains a widely used prognostic scoring system in many clinical practices; however it is not useful in predicting response to treatment in MM...

Multiple myeloma (MM) is an incurable disease characterized by clonal plasma cell proliferation and overproduction of monoclonal paraprotein, hypercalcemia, renal failure, anemia, osteolytic bone lesions, and infections. Melphalan, a nitrogen mustard, is an alkylating agent synthesized in 1953, and it has been used in multiple myeloma therapy for fifty years. Although novel agents have been introduced in the past few decades improving prognosis of the disease, melphalan still maintains a crucial role in the treatment of MM acting both as cytotoxic agent through damage to DNA, and as immunostimulatory drug by inhibiting Interleukin-6, as well as interaction with dendritic cells, and immunogenic effects in tumor microenvironment...

BACKGROUND: The monoclonal gammopathies are a group of plasma-cell proliferative disorders characterized by the secretion of monoclonal immunoglobulin (M protein or paraprotein). Some rare cases have revealed the specific affinity of paraprotein as autoantibody. Here we report a patient with monoclonal gammopathy of undetermined significance (MGUS) accompanied by a remarkable increase of anticardiolipin antibody (aCL) and an extensively decreased coagulation factor activity, however, without any clinical signs of antiphospholipid syndrome (APS) and bleeding...

Multiple myeloma (MM) is a clonal proliferation of malignant plasma cells in the bone marrow (BM) that secretes monoclonal paraproteins in the blood serum and urine. Bone marrow MM cells can invade and damage the functions of other tissues and organs, such as the lungs, spleen, liver, pancreas, kidneys and lymph nodes. However, the invasion of MM cells primarily located in the BM to the anterior mediastinum at the site of the thymus is an extremely rare event. The current study reports the case of a 53-year-old female who presented with MM with involvement of the anterior mediastinum...

Multiple myeloma (MM) is a plasma cell neoplasm and constitutes 10% of hematologic malignancies. Malignant myelomatous pleural effusions are very rare and occur in <1% of cases of MM. In this article, we report a rare case of a patient who initially presented with pleural effusion and was subsequently found to be secondary to MM with an underlying raised IgG paraprotein. The patient symptomatically improved and was in partial remission with palliative radiotherapy, VTD chemotherapy, and bisphosphonates.

BACKGROUND: Light chain amyloidosis (AL) is a rare deposition disease and is present in 10-15% of patients with myeloma (MM). In contrast to symptomatic AL in MM, presence of bone marrow (BM) amyloid deposits (AD) in MM is not connected to kidney damage. Renal AD but not BM-AD occur mostly in MM with lambda paraprotein (lambda MM). METHODS: We investigated amyloid presence in BM clots taken at diagnosis in 84 patients with symptomatic MM and compared disease characteristics in MM with kappa paraprotein (kappa MM)/lambda MM with and without BM-AD...

Lymphoplasmacytic lymphoma is a rare low-grade B-cell lymphoma, which is composed of a mixture of small lymphocytes, plasmacytoid cells and plasma cells that typically infiltrate the bone marrow, but lymph nodes and rarely other organs can be involved as well. Waldenström macroglobulinaemia is a lymphoplasmacytic lymphoma with typical bone marrow involvement and is associated with detectable IgM paraproteins. The diagnosis of lymphoplasmacytic lymphoma/Waldenström macroglobulinaemia (LPL/WM) can be challenging, due to similarities to other small B-cell lymphomas with plasmacytic differentiation and/or with IgM paraproteins...

INTRODUCTION: Therapeutic plasma exchange (TPE) can be proposed in the treatment of chronic dysimmune peripheral neuropathies (CDPN). Actual guidelines are however based on few studies, and indications and protocols still remain to be clarified. We conducted a 10-year retrospective study in order to assess the effectiveness and tolerance of TPE in CDPN. METHODS: All patients treated for CDPN with TPE from October 2006 to March 2016 in the university hospital of Angers were included...

BACKGROUND: Knowledge of human IgG subclass antibody responses to various allergens has been hampered by a lack of reliable standardized assays. The aim here was to develop quantitative immunoassays for human IgG1, IgG2, and IgG3 antibodies using ImmunoCAP® technology and to evaluate their application. METHODS: Enzyme conjugates with isotype-specific monoclonal antibodies and calibrators composed of purified myeloma paraproteins were developed for each assay and used together with other standardized assay reagents for the Phadia® 100 instrument...

Mercury Lin, Mark Haas
Plasma cell dyscrasias are associated with a variety of renal diseases, most resulting from the deposition of intact or altered monoclonal paraproteins within the renal parenchyma. Much less commonly, renal disease resulting from monoclonal gammopathies has been reported without actual accumulation of the paraprotein or a derivative of it within the kidney. One such instance involves thrombotic microangiopathy (TMA), which is a consequence of endothelial cell injury. New data from the Mayo Clinic indicate that the association of TMA with monoclonal gammopathies is far more frequent than previously appreciated...

BACKGROUND: Monoclonal immunoglobulins (paraproteins) are produced by B lymphocytes in lymphoproliferative disorders. A single monoclonal immunoglobulin is homogeneous in terms of its structure, and it can occur in human serum at high concentration and cause significant interference in laboratory assays. CASE: We present a case of an 84-year-old man who was admitted to the hospital for progression of dyspnea. Basic laboratory tests showed a serum concentration of conjugated bilirubin, measured using the diazo spectrophotometric method, which was much higher than that of total bilirubin...

Monoclonal antibodies represent a standard part in the treatment of oncologic patients, but their efficacy in multiple myeloma used to be unsatisfactory. Daratumumab monotherapy was approved by the American FDA in 2015, after unprecedented results were obtained in a heavily pre-treated group of patients. In 2016 daratumumab was approved in combination with lenalidomide and dexamethasone, or bortezomib and dexamethasone, for the treatment of myeloma patients who have received at least one prior therapy.The toxicity of the drug is low, and is dominated by infusion-related reactions in more or less half of patients...
