BACKGROUND: Multiple myeloma is consistently preceded by monoclonal gammopathy of undetermined significance (MGUS), which is usually only treated by a form of anti-multiple myeloma therapy if it is causing substantial disease through deposition of secreted M proteins. However, studies comparing how MGUS and multiple myeloma plasma cell clones respond to these therapies are scarce. Biclonal gammopathy multiple myeloma is characterised by the coexistence of an active multiple myeloma clone and a benign MGUS clone, and thus provides a unique model to assess the responses of separate clones to the same anti-multiple myeloma therapy, in the same patient, at the same time...

BACKGROUND: Multiple Myeloma is a cancer of plasma cells associated with significantly reduced survival. Long term survivorship from myeloma is very rare and despite advances in its treatment the disease is generally considered incurable. We report a patient diagnosed with myeloma carrying a germline mutation of a tumour suppressor gene who has effectively been cured. CASE PRESENTATION: A 36-year-old woman was diagnosed with IgG lambda myeloma in 1985. She was treated with melphalan chemotherapy followed by high-dose melphalan and autologous stem cell rescue and since remained in complete remission despite not having received any additional therapy...

Multiple myeloma (MM) and its pre-cancerous stage monoclonal gammopathy of undetermined significance (MGUS) allow to study immune responses and the chronology of inflammation in the context of blood malignancies. Both diseases are characterized by the production of a monoclonal immunoglobulin (mc Ig) which for subsets of MGUS and MM patients targets pathogens known to cause latent infection, a major cause of inflammation. Inflammation may influence the structure of both polyclonal (pc) Ig and mc Ig produced by malignant plasma cells via the sialylation of Ig Fc fragment...

OBJECTIVE: To explore the effect of recombinant human erythropoietin (rhEPO) on myeloma cell line MPC-11 in vitro and its anti-tumor mechamism so as to provide the theoretic evidence for treatment of multiple myeloma by using rhEPO. METHODS: MPC-11 cells were cultured in RPMI 1640 medium, then the MPC-11 cells in logarithmic growth phase were seed in 96 well culture plates at a density of 1×10(4)/ml cells with 100 µl per well. For all the experiments, the control and rhEPO groups were set up, and the rhEPO group was divided into different concentration groups: 20, 40, 60, 80, 100, 200 and 400 rhEPO U/ml...

Monoclonal gammopathy of undetermined significance (MGUS) is a common haematological disorder characterized by the presence of a monoclonal protein (M-protein). MGUS is considered an asymptomatic 'innocent' pre-malignant precursor condition of - mostly - multiple myeloma, without indication for treatment. We present three cases illustrating that MGUS can lead to serious problems. The first patient, a 51-year-old female, presented with polyneuropathy due to anti-MAG antibodies related to IgM MGUS. The second patient, a 37-year-old female, presented with proteinuria due to immunotactoid glomerulopathy caused by renal monoclonal IgG deposition associated with MGUS...

Autoimmune autonomic ganglionopathy is an autonomic disorder that occurs as a symptom of paraneoplastic neurological syndrome. To date, there have been no reports on multiple myeloma with autoimmune autonomic ganglionopathy. A 37-year-old Japanese woman suffered from orthostatic hypotension was diagnosed with multiple myeloma (IgG kappa type), and a serological examination revealed the presence of anti-ganglionic nicotinic acetylcholine receptor (anti-gAChR) antibodies. She was treated for multiple myeloma, as a result, the autonomic disturbance improved and her anti-gAChR antibody titer decreased to undetectable levels, despite the fact that she only achieved a partial remission of multiple myeloma...

OBJECTIVE: The aim of this study was to understand the influence of disease and patient characteristics on exposure to daratumumab, an immunoglobulin Gκ (IgGκ) monoclonal antibody, and clinical outcomes in relapsed or refractory multiple myeloma (MM). PATIENTS AND METHODS: Baseline myeloma type, albumin levels, renal/hepatic function, age, sex, race, weight, Eastern Cooperative Oncology Group (ECOG) status, refractory status, and number of prior therapies were evaluated using data from two clinical studies-GEN501 (N = 104) and SIRIUS (N = 124)...

Subsets of mature B cell neoplasms are linked to infection with intracellular pathogens such as Epstein-Barr virus (EBV), hepatitis C virus (HCV), or Helicobacter pylori. However, the association between infection and the immunoglobulin-secreting (Ig-secreting) B proliferative disorders remains largely unresolved. We investigated whether the monoclonal IgG (mc IgG) produced by patients diagnosed with monoclonal gammopathy of undetermined significance (MGUS) or multiple myeloma (MM) targets infectious pathogens...

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...
