Serum bioactive but not immunoreactive interleukin-6 (IL-6), and serum C-reactive protein (CRP), have been reported to be of prognostic significance in multiple myeloma (MM). We measured serum immunoreactive IL-6 by a sensitive enzyme-linked immunosorbent assay in 30 MM patients at diagnosis. In 30% of the patients serum immunoreactive IL-6 exceeded the(More)
High serum level of bioactive interleukin-6 (IL-6) is regarded as a predictor of poor prognosis in multiple myeloma (MM). On the other hand, the reported levels of immunoreactive IL-6 have been highly variable, and the prognostic value of immunoreactive IL-6 in MM is not clear. We have analyzed the prognostic significance of serum immunoreactive IL-6, as(More)
Beta-2-microglobulin (B2M) forms the small invariable light chain subunit of class I HLA antigens on the cell membrane of all nucleated cells. During the continuous turnover of the HLA molecules, B2M is shed from the cell membrane into blood. Lymphocytes are the main source of serum free B2M. Serum B2M concentration is increased in renal diseases, various(More)
Cyclin-dependent kinase 5 (cdk5)/p35 kinase activity is highest in post-mitotic neurons of the central nervous system and is critical for development and function of the brain. The neuronal specific activity of the cdk5/p35 kinase is achieved through the regulated expression of p35 mRNA. We have identified a small 200-bp fragment of the p35 promoter that is(More)
Interleukin-6 (IL-6) is a major growth factor for the clonal malignant plasma cells in multiple myeloma (MM). The effect of IL-6 may be enhanced by soluble IL-6 receptor (sIL-6R). As there is a clinical need for improved stratification of MM patients at diagnosis, we have studied the role of sIL-6R as a prognostic marker in 207 newly diagnosed MM patients.(More)
The androgen-induced proliferation of S115 mouse mammary tumor cells has been suggested to involve autocrinic fibroblast growth factor signaling. Heparan sulfate proteoglycans are required for fibroblast growth factor signaling, presumably due to their ability to alter binding of fibroblast growth factors to their receptors. We have investigated the role of(More)
BACKGROUND AND OBJECTIVES We wanted to establish a permanent national database system, which can be utilized to study transfusion recipients and blood use in Finland. MATERIALS AND METHODS A regularly updated register for permanent use was developed. To study the usability of the database, years 2002 and 2003 were further analysed. Database included all(More)
Peripheral blood lymphocyte subsets were analysed by flow cytometry and compared among 43 patients with untreated multiple myeloma (MM), 16 patients with monoclonal gammopathy of undetermined significance (MGUS) and 26 controls. The age and sex distributions of the patients and controls were comparable, which is important, since in the controls there was a(More)
DNA content of both bone marrow and peripheral blood mononuclear cells was measured by flow cytometric analysis in 46 patients with untreated multiple myeloma and 15 patients with benign monoclonal gammopathy to clarify further the incidence and clinical correlations of DNA aneuploidy. Aneuploidy was detected in the bone marrow of 25 multiple myeloma(More)
Descriptive information on platelet (PLT) recipients, particularly during surgery, is limited. A description of the current epidemiology of PLT-transfused patients is required to optimize platelet transfusion care and to follow trends in PLT use. In 2004 and 2005, information was combined from several computerized medical systems. Participating hospitals (9(More)
