BACKGROUND: Serum and urine protein electrophoreses and immunofixation electrophoreses are the gold standards in diagnosing monoclonal gammopathy. Identification of oligoclonal bands in post-treatment patients has emerged as an important issue and recording the location of the malignant monoclonal peak may facilitate prospective identification of a new "monoclonal" spike as being distinct from the malignant peak. METHODS: We recorded the locations of monoclonal spikes in descriptive terms, such as being in the cathodal region, mid-gamma region, anodal region, and beta region...

BACKGROUND: Over the past three decades much has changed in the treatment and outcomes of patients suffering concurrently from both multiple myeloma (MM) and HIV. While the prevalence of MM appears to be higher in HIV-positive individuals than in those who are uninfected, early recognition of patients suffering from both diseases is difficult and little information is available on their demographics and clinical presentation. OBJECTIVE: To compare the presenting features of HIV-positive patients diagnosed with MM with those of HIV-negative patients...

C-methionine (MET) positron emission tomography (PET) is more sensitive than F-fluorodeoxyglucose (FDG)-PET for detecting myeloma lesion. Many clinical studies support this evidence mainly for multiple myeloma cases of IgG or IgA subtypes. However, this is not confirmed for low monoclonal protein-producing myelomas, such as IgD, IgE, and nonsecretory type. We encountered a 71-year-old man with IgD λ-type myeloma. In this patient, FDG-PET did not reveal any abnormal uptake lesions, whereas MET-PET revealed diffuse bone marrow uptake that relieved after initial chemotherapy...

Dear Editor, An 83-year-old woman developed yellow-brownish infiltrates, nodules, and tumors mimicking xanthomas, mostly involving the periorbital and chest area within three months (Figure 1). She had no abnormalities in serum cholesterol or triglycerides levels. A detailed laboratory analysis revealed the presence of mild monoclonal gammopathy with a presence of immunoglobulin G (IgG) kappa light chains; however, according to hematologist consultation, it did not require medical intervention. Imaging assessment and ultrasound examination did not show any specific involvement of internal organs...

Multiple myelomas (MM) of the immunoglobulin D (IgD) subtype is rare amongst plasma cell malignancies. It can present a diagnostic challenge because of the low amount of immunoglobulin in the serum. The amount of monoclonal (M)-protein is often undetectable on electrophoresis. Historically, survival in these patients was typically shorter compared to the immunoglobulin A (IgA) and immunoglobulin G (IgG) subtypes due to advanced disease upon presentation. With the advent of better diagnostic techniques, the prognosis of this disease is changing...

We assessed the ability of a mass spectrometry-based technique, called monoclonal immunoglobulin rapid accurate mass measurement (miRAMM), to extend the analytical range of M-protein detection in serum samples obtained from myeloma patients in stringent complete response (sCR) post-autologous stem cell transplant (ASCT). To aid the M-protein detection post ASCT, the accurate molecular mass of the M-protein light chain at diagnosis was determined in all patients (N=30) and used to positively identify clones in the sCR serum...

CASE SUMMARY: Herein a drug-resistant IgG-lambda-type multiple myeloma associated with probable phaeochromocytoma in a cat is described. A 12-year-old cat presented with weakness, weight loss, progressive blindness and open-mouth breathing, in addition to polyuria and polydipsia of 2 months' duration. Abdominal ultrasonography revealed a left adrenal mass. Phaeochromocytoma was suspected on the basis of cytology and was associated with systemic hypertension. Biochemistry showed hyperproteinaemia...

Solitary bone plasmacytoma (pso) is a rare tumor, made of malignant plasma cells observed in a single bone, and without systemic proliferation. We report the case of a 33 year-old man who was admitted with chronic demyelinating sensorimotor polyneuropathy. Immunoelectrophoresis with immunofixation of serum proteins showed a monoclonal peak igg with lambda light chain and the workup was in favour of right hipbone secreting solitary plasmacytoma. The patient was treated with radiotherapy and steroids, and the evolution has been marked by a partial recovery of the motor deficit...

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...

In 2015, 2 monoclonal antibodies were approved for the treatment of relapsed or refractory multiple myeloma (RRMM), elotuzumab and daratumumab. Elotuzumab is a monoclonal IgG-κ antibody directed against SLAMF7 (signaling lymphocytic activation molecule F7), a cell surface receptor involved in natural killer cell activation. Daratumumab is a monoclonal IgG-κ antibody that binds to CD38, a transmembrane protein found on the surface of myeloma cells and responsible for cellular adhesion and ectoenzymatic activity...

A 75-year-old woman developed a moderately severe rash about a week and a half after the start of bortezomib (Btb)-based chemotherapy for IgG lambda multiple myeloma; at the time, she was also receiving acyclovir as antiviral prophylaxis in addition to herpes zoster (HZ) vaccination. HZ reactivation rate is high in Btb recipients; therefore, the timing of antiviral prevention is critical in relation to Btb. Attempts were made to identify the offending agent based on the timing of drugs administered and the appearance of skin lesions in relation to other drugs...

BACKGROUND: Monoclonal immunoglobulin deposition disease (MIDD) is characterized by the non-amyloid deposition of monoclonal immunoglobulin fragments in the basement membranes. Heavy chain deposition disease (HCDD) is a type of MIDD. HCDD is an extremely rare disease, and only three cases have been reported in Japan up to the present. The prognosis of HCDD is very poor, and optimal treatment has not been established. Only a few cases of HCDD with favorable long-term renal prognosis have been reported to date...

Daratumumab (Darzalex, Janssen Biotech) is a clinically approved antibody targeting CD38 for the treatment of multiple myeloma. However, CD38 is also expressed by other cancer cell types, including lung cancer, where its expression or absence may offer prognostic value. We therefore developed a PET tracer based upon daratumumab for tracking CD38 expression, utilizing murine models of non-small cell lung cancer to verify its specificity. Daratumumab was prepared for radiolabeling with (89)Zr (t1/2 = 78.4 h) through conjugation with desferrioxamine (Df)...
