Multiple myeloma as the first manifestation of acquired immunodeficiency syndrome: a case report and review of the literature.

Various hematologic malignancies and solid tumors are increasingly diagnosed in patients with human immunodeficiency virus (HIV) infection and may be the presenting manifestation of acquired immunodeficiency syndrome (AIDS). Multiple myeloma, however, has never been reported as the presenting manifestation of AIDS. We report on a 34-year-old man who presented with back pain, paresthesias, paraparesis, vertebral bony disease, and an associated soft tissue mass.

Evaluation of argyrophilic nucleolar organiser regions (AgNORs) in multiple myeloma.

Aim: To investigate the prognostic value of argyrophylic nucleolar organiser regions (AgNORs) in multiple myeloma.

Methods: Bone marrow aspirates from 55 newly diagnosed patients with multiple myeloma were stained with the one step AgNO3 technique. The mean number of AgNORs in each plasma cell nucleus (AgNOR count) was tested for a possible correlation with other clinical and laboratory variables at presentation (clinical stage, substage, heavy and light chain isotype, haemoglobin concentration, platelet count, marrow infiltration rate, degree of skeletal lesions, M protein concentration, plasma cell morphology, and serum concentrations of calcium, albumin, lactate dehydrogenase, C reactive protein, and beta 2 microglobulin) and with outcome (response to first line treatment, first remission duration, and overall survival).

Serum transforming growth factor-beta 1 is related to the degree of immunoparesis in patients with multiple myeloma.

The expansion of myeloma cells is regulated by cytokines, among which IL-6 is a major growth factor. It has been recently suggested that serum transforming growth factor beta 1 (TGF beta 1), a cytokine found in large amounts in alpha-granules of platelets, might play a role in multiple myeloma (MM). It was the purpose of this study to determine serum TGF beta 1 levels in MM patients and to seek a correlation with disease parameters.

Predictive factors affecting mobilization and peripheral blood stem cell (PBSC) collection using single apheresis (SA) for rescuing patients after high-dose chemotherapy (HD.CHE) in various malignancies.

We have investigated factors that affect the efficiency of single apheresis (SA) before transplant and define groups of patients that may require more than one collection for hematologic support. A consecutive series of 56 patients with hematologic malignancies and solid tumours had peripheral blood stem cells (PBSC) collected following mobilization with colony-stimulating factors (CSF) alone or after conventional chemotherapy (CHE) or high-dose cytoxan (HD.CY) followed by CSF.

Soluble interleukin-6 receptor (sIL-6R), a new prognostic factor in multiple myeloma.

sIL-6R is a 55 kD soluble molecule mediating the interleukin-6 (IL-6) signal through the IL-6 receptor-associated transmembrane signal transducer, gp130. It has recently been suggested that sIL-6R serum levels may reflect disease severity in multiple myeloma (MM). We determined sIL-6R serum levels in 25 normal controls (NC) and in 80 MM patients at diagnosis and during the course of the disease.
