The in vitro proliferative response against a recombinant 65 kD Mycobacterium bovis protein that has 100% homology with the 65 kD protein of M tuberculosis was tested in synovial fluid and peripheral blood mononuclear cells from patients with rheumatoid arthritis (RA) and other types of chronic arthritis. An acetone precipitate (AP) of M tuberculosis, and a(More)
We determined interleukin-6 (IL-6) levels in the serum of 212 well-defined patients with newly diagnosed paraproteinaemia and evaluated its discriminatory value and prognostic role in multiple myeloma (MM). Results were compared with serum neural cell adhesion molecule and beta-2-microglobulin, both established prognostic MM markers.(More)
A higher prevalence of solid tumours in patients with M(onoclonal) proteinaemia without a co-existing haematological malignancy has been reported. We investigated this association by linking a population-based registry of patients with newly diagnosed M-proteinaemia (n = 1464) with the Regional Cancer Registry. Patients were followed for a median of 7.4(More)
In the past decade, patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL) were treated with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) therapy. Standard treatment is now changing as a result of deeper understanding of underlying biologic differences of such lymphomas. One of the most powerful predictors of an(More)
BACKGROUND The treatment of posttransplant lymphoproliferative disorder (PTLD) remains empirical. We review our treatment of seven cases of PTLD consisting of five interventions: 1) reduction of immunosuppression; 2) antiviral drugs; 3) interferon-alpha; 4) gamma-globulins; and 5) anti-CD19 monoclonal antibodies. METHODS AND RESULTS; Seven consecutive(More)
BACKGROUND The effect of interferon-alpha 2b (IFN-alpha-2b) on progression-free and overall survival as well as quality of life (QoL) was studied in mainly elderly patients with multiple myeloma (MM), who reached a plateau phase after melphalan/prednisone induction. PATIENTS AND METHODS In an open phase III trial, 262 patients, median age 69 years (range(More)
UNLABELLED This study assesses whether new treatment strategies developed in clinical trials translate into improved survival for multiple myeloma (MM) patients in the Netherlands. All patients diagnosed with MM in the Northern part of the Netherlands between 1989 and 2005 were retrieved from two regional population-based cancer registries. Information on(More)
Whether the response to chemotherapy is a prognosticator in multiple myeloma (MM) is still not known. Therefore, the relationship between survival and the rate of monoclonal protein (M-protein) decrement during the first cycles of therapy was prospectively assessed in 262 patients with newly diagnosed MM that were included in a phase III trial (HOVON-16).(More)
