We report the case of a 54 years old patient monitored for a monoclonal IgG kappa light chain refractory relapsed multiple myeloma and receiving daratumumab immunotherapy. Daratumumab (DARA), a monoclonal anti-CD38 antibody, belongs to the new generation of immunotherapy in refractory relapse multiple myeloma which the medical pathologist should be aware of to avoid misinterpretation of biological tests performed for patients followed for this disease. By its IgG1K humanized monoclonal antibody backbone, DARA interferes in both serum protein electrophoresis and immunofixation by the presence of an alternate IgGK monoclonal peak, leading to a possible difficulty to assess treatment's response in monoclonal IgG kappa light chain myeloma...

Determination of the protein composition of urine is a non-invasive method helping to diagnose renal lesions and evaluate therapeutic interventions. We present here five observations that highlight the performance and relevance of urine protein analysis combining selected glomerular and tubular protein measurements. Total urine protein level and measurements of urinary IgG, albumin, transferrin alpha-1 microglobulin and retinol binding protein were performed on a urine sample by immunonephelometry. The results were normalized for urine creatinine concentration and integrated in the MDI interpretation software that provides a "urine protein profile" (UPP)...

We used suncus (Suncus murinus; house musk shrew) to generate partner cells for cell fusion to produce suncus monoclonal antibodies. Suncus are insectivores that are genetically distant to rodents, and recognize antigens and epitopes that are not immunogenic in mice and rats, which are the animals most commonly used in basic life science research and from which monoclonal antibodies are usually produced. To date, monoclonal antibodies from suncus have not been generated due to the lack of a plasmacytoma fusion partner...

Myeloma cast nephropathy is a major complication of multiple myeloma. Recent evidence has demonstrated that the earlier induction of bortezomib-based chemotherapy with plasma exchange (PE) provides better results for kidney function and patient survival. Due to its non-selectivity, PE with albumin replacement carries the risk of fibrinogen loss, leading to bleeding. We herein report a case of successful treatment of myeloma cast nephropathy using bortezomib-based chemotherapy and selective PE. A 61-year-old woman who had a 20-year history of type II diabetes mellitus was admitted to our hospital for the evaluation of hypercalcemia, severe kidney dysfunction, and anemia...

The emergence of oligoclonal bands (OB) in patients with multiple myeloma achieving a complete remission (CR) after autologous stem cell transplantation (ASCT) and the use of novel agents is a well-recognized event. The presence of OB is associated with favorable outcome. However, the emergence of OB in light-chain (AL) amyloidosis has never been investigated. The aim of the study was to determine the incidence, natural history, and prognostic impact of OB in 50 patients with AL amyloidosis who achieved at least a partial response either after upfront ASCT (20 patients [40%]) or after conventional treatment in patients ineligible for transplantation (30 patients [60%])...

REVIEW
Evan Rosenbaum, Douglas Marks, Shahzad Raza
Neuropathies associated with plasma cell dyscrasias are a major cause of morbidity for patients managed by medical oncologists. Because of similarities in clinical presentation and on nerve conduction studies, identifying the underlying disease leading to a paraproteinemic neuropathy can often be difficult. In addition, the degree of neurologic deficit does not strictly correlate with the extent of abnormalities on common clinical laboratory testing. Fortunately, with increasing understanding into the biologic mechanisms of underlying hematologic diseases, additional biomarkers have recently been developed, thus improving our diagnostic capacity...

BACKGROUND: Proliferative glomerulonephritis with monoclonal IgG deposits (PGNMID) is a form of renal involvement by monoclonal IgG deposits that was found in mesangial, subendothelial or subepithelial regions. The distribution of glomerular deposits was completely different from that in monoclonal immunoglobulin deposition disease. PGNMID is reported to be rarely associated with a hematological malignancy. Previously, only five cases of PGNMID with multiple myeloma have been reported...

Ectoenzymes are cell surface molecules, which represent functional bridges between the environment and the cytoplasm. One set of ectoenzymes-CD39, CD38, CD203a, and CD73-leads to the generation of adenosine (ADO) by metabolizing ATP and NAD(+). While ADO is known to control inflammation and suppress immune responses, other aspects of ADO function are still obscure, mainly due to its short half-life in biological fluids. Human multiple myeloma (MM) grows in the closed system of the bone marrow (BM) niche representing an ideal setting for studying ectoenzymes and their products...

Immunoglobulin G (IgG) metabolism has received much attention in the literature for two reasons: (i) IgG homeostasis is regulated by the neonatal Fc receptor (FcRn), by a pH-dependent and saturable recycling process, which presents an interesting biological system; (ii) the IgG-FcRn interaction may be exploitable as a means for extending the plasma half-life of therapeutic monoclonal antibodies, which are primarily IgG-based. A less-studied problem is the importance of endogenous IgG metabolism in IgG multiple myeloma...

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.

A broad spectrum of diseases are associated with IgM monoclonal gammopathy, including Waldenstrom macroglobulinemia (WM), various types of B cell non-Hodgkin's lymphoma (NHL), multiple myeloma (MM), primary amyloidosis (AL), and monoclonal gammopathy of undetermined significance (MGUS); these are called IgM monoclonal gammopathy related diseases (IgM-RD). We investigated MYD88 L265P and WHIM-like CXCR4 mutations in various IgM-RD. Patients with serum immunofixation electrophoresis confirmed IgM monoclonal gammopathy who had enough material for DNA extraction and presented between January 2008 and October 2016 at Peking Union Medical College Hospital were enrolled in this cohort...

We identified B cell maturation antigen (BCMA) as a potential therapeutic target in 778 newly diagnosed and relapsed myeloma patients. We constructed an IgG-based BCMA-T cell bispecific antibody (EM801) and showed that it increased CD3(+) T cell/myeloma cell crosslinking, followed by CD4(+)/CD8(+) T cell activation, and secretion of interferon-γ, granzyme B, and perforin. This effect is CD4 and CD8 T cell mediated. EM801 induced, at nanomolar concentrations, myeloma cell death by autologous T cells in 34 of 43 bone marrow aspirates, including those from high-risk patients and patients after multiple lines of treatment, tumor regression in six of nine mice in a myeloma xenograft model, and depletion of BCMA(+) cells in cynomolgus monkeys...
