Nineteen individuals are reported who represent nine familial instances of various immunopathies. Multiple myeloma was diagnosed in 10 members of five families, lanthanic (idiopathic) paraproteinemia in five members of two families and either myeloma or lanthanic paraproteinemia in four members of the remaining two families. The parent-child relationship(More)
INTRODUCTION Recent studies suggest that multiple myeloma (MM) triggers osteoclastogenesis by disrupting the balance between the receptor activator of NF-kappaB ligand (RANKL) and osteoprotegerin (OPG), its natural antagonist. MATERIAL/METHODS Determinations of bone marrow (BM) and serum OPG and sRANKL concentrations were performed in 133 MM patients and(More)

Immunofixation (IFE) is a standard method for detecting monoclonal immunoglobulins and characterizing its isotype. Recently clonality can also be determined by using immunoglobulin (Ig) heavy chain/light chain immunoassays - HLC, HevyliteTM. HLC separately measures in pairs light chain types of each intact Ig class generating ratios of monoclonal(More)
The surface expression of CD117 antigen (c-kit) on plasma cells from 158 multiple myeloma (MM), 12 plasma cell leukemia (PCL), 7 MGUS, 7 IgM lymphoplasmacytic lymphoma patients and 10 healthy subjects has been analyzed by flow cytometry using triple staining with the monoclonal antibodies CD138, CD117 and CD38. The antigen expression intensity was(More)
Prospective flow cytometric analysis of antigens expression on bone marrow and peripheral blood plasma cells of 36 plasma cell leukemia (PCL) patients enabled to establish the following immunophenotype of leukemic plasma cell: CD38(++), CD138(+), CD54(+), CD49d(+), CD29(+), CD44(+), CD126(+), CD19(-), CD45(-). In one-third of patients PCL cells express(More)
The aim of this prospective, long-term study was to define the flow cytometric characteristics of plasma cell CD56 expression as well as determine the clinical characteristics of 204 multiple myeloma (MM) patients and 26 plasma cell leukemia (PCL) patients with regard to CD56 expression. CD56 expression intensity was determined by measurement of antigen(More)
In this prospective study we determined the incidence of intact/fragmented immunoglobulin and Bence Jones protein in urine immunofixation using Sebia reagents and HydrasysTM 2 apparatus and compared the results to concentrations of serum free light chains (FLC) assessed using Siemens BNTM II nephelometer and the immunoassay Freelite (Binding Site) in 289(More)
Osteolytic bone destruction, caused by the aberrant production and activation of osteoclasts, results in significant morbidity for patients with multiple myeloma (MM). Pamidronate [(3-amino-1-hydroxypropylidene)-1,1-bis-phosphonate] inhibits osteoclastic activity and reduces bone resorption. A potency of zoledronic acid(More)
