Multiple myeloma (MM) is a proliferative disorder of plasma cells which produce abnormal immunoglobulin proteins. Skin involvement is rarely found in this disorder. They are either specific or nonspecific lesions. We report four such interesting patients who presented to us initially with common dermatoses such as leukocytoclastic vasculitis, pyoderma gangrenosum, and vesiculobullous disorders and were subsequently diagnosed to have MM. There were no skeletal involvements or renal function abnormality at the time of presentation...

OBJECTIVES: Alpha-1 antitrypsin (A1AT) deficiency is associated with emphysema and liver disease. Only plasma-derived A1AT protein is available for augmentation therapy. Recombinant A1AT (recA1AT) protein expressed in various types of available hosts are either non-glycosylated or aberrantly glycosylated resulting into reduced stability and biological activity. To overcome these limitations, we have used the human liver HepG2 cell line to produce recA1AT protein. RESULTS: HepG2 cells were transfected by A1AT cDNA and cell populations were generated that stably overexpressed A1AT protein...

There is a growing interest among mink ranchers to select their stock for tolerance to the Aleutian mink disease virus (AMDV). Enzyme-linked immunosorbent assays (ELISA) are used to identify mink which have low anti-AMDV antibody titres and are expected to tolerate the AMDV infection. The objective of this study was to calculate the accuracy of three ELISA systems which were performed on blood or serum of AMDV-inoculated American mink (Neovison vison) at five laboratories in Canada, USA, Finland, the Netherlands and Denmark...

A 10-year-old female spayed mixed breed cat with a subcutaneous mass on the right hind limb was revealed with bimodal monoclonal gammopathy composed of IgA by immunoelectrophoresis and immunofixation. Approximately 1 month after referral, the cat died due to renal failure. Postmortem immunohistopathologic evaluation of the subcutaneous mass revealed neoplastic cell proliferation of plasma cells and giant myeloma cells. Neoplastic cells were also present in the liver and spleen. These results led to the diagnosis of a rare case of feline myeloma-related disorders with extramedullary plasmacytoma infiltrating in multiple locations...

A 68-year-old man was hospitalized and examined for renal impairment. A laboratory analysis showed hypercalcemia. Although the serum parathyroid hormone and serum 1-25(OH)2 vitamin D3 levels were not elevated, the serum parathyroid hormone-related peptide (PTHrP) level was increased. Immunoelectrophoresis of the urine and bone marrow aspiration indicated multiple myeloma (MM). He was diagnosed with the coexistence of cast nephropathy and light chain deposition disease by a renal biopsy. Notably, PTHrP expression was detected in the myeloma cells based on immunohistochemistry and in situ hybridization...

Multiple myeloma (MM) is a rare hematological malignancy, characterized by uncontrolled proliferation of plasma cells in the bone marrow. MM is usually confined to the bone marrow, however, it may occasionally infiltrate other tissues, which is known as extramedullary plasmacytoma (EMP). The majority of EMPs involve the head and neck region, although different anatomical sites, including the gastrointestinal tract, central nervous system, thyroid gland and breast may also be affected. The simultaneous presentation of EMP in the kidney and head is rare, presenting diagnostic challenges due to its unusual location and non-specific or absent symptoms...

For detection of Aleutian mink disease virus (AMDV) antibodies, an enzyme-linked immunosorbent assay (ELISA) was developed using the recombinant VP2332-452 protein as an antigen. Counterimmunoelectrophoresis (CIEP) was used as a reference test to compare the results of the ELISA and Western blotting (WB); the specificity and sensitivity of the VP2332-452 ELISA were 97.9% and 97.3%, respectively, which were higher than those of WB. Therefore, this VP2332-452 ELISA may be a preferable method for detecting antibodies against AMDV...

We herein report the case of an elderly patient with light-chain deposition disease (LCDD) successfully treated with bortezomib. An 83-year-old woman was admitted because of nephrotic syndrome. She was diagnosed to have monoclonal gammopathy of undetermined significance (IgG-κ type) and LCDD, on the basis of serum and urinary immunoelectrophoresis and renal biopsy. She responded to a modified regimen of bortezomib-based chemotherapy with disappearance of proteinuria without any adverse effects. According to a literature review of 16 cases, including the present case, bortezomib-based chemotherapy appears to be a convincing strategy for the treatment of LCDD even in elderly patients...
