Megakaryocyte and erythroid colony formation in vitro by progenitors from the bone marrow and/or blood was studied in 61 patients with essential thrombocythaemia (ET) and 22 patients with reactive thrombocytosis (RT) using the methyl cellulose assay. 47 (77%) of the patients with ET showed megakaryocyte and/or erythroid spontaneous colony formation while 14(More)
Platelet refractoriness arising from HLA alloimmunization is a serious complication of transfusion therapy. In a prospective randomized trial, white cell (WBC)-reduced blood components were compared to standard platelet and red cell concentrates with respect to alloimmunization, refractoriness, and platelet increments after transfusion. Sixteen of 31 adult(More)
Forty patients with high risk myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) preceded by MDS were treated with intensive induction and consolidation chemotherapy in a prospective multicenter pilot study. They were given two cycles of cytarabine 100 mg/m with 12-h intervals on days 1-7 and idarubicin 12 mg/m2 on days 5-7, both intravenously.(More)
Platelet refractoriness arising from HLA immunization develops in 20-50% of multitransfused patients with hematologic malignancies. We retrospectively analyzed the efficiency of leukocyte-depleted blood components in preventing refractoriness in 140 adult patients with acute myeloid leukemia (AML), treated according to a standardized cytostatic protocol.(More)
A 47-year-old female with acute myeloid leukemia received HIV positive platelets during induction chemotherapy. 18 days later, coincident with the recovery of the bone marrow function, she developed an erythematous rash, mild lymphadenopathy, and nausea which disappeared within 10 days. A week later mild CSF pleocytosis consisting of mature lymphocytes and(More)
This study attempts to combine the technological possibilities of 3D-game environments and collaborative learning scripts. The study is a design experiment (N = 64) with multiple data collection and analysis (quantitative and qualitative) methods. The aims were twofold: The aim was to develop a game environment to simulate issues of work safety in a(More)
A randomised multicentre study was conducted among patients over 65 yr of age with newly diagnosed acute myeloid leukaemia (AML) to compare oral treatment with etoposide 80 mg/m(2) and thioguanine 100 mg/m(2) twice daily on 5 d and idarubicin 15 mg/m(2) on 3 d (ETI) to a mainly i.v. combination of cytarabine 100 mg/m(2) twice daily on 5 d, idarubicin 12(More)
The tolerability and kinetics of a solvent-detergent-treated 6% intravenous immunoglobulin (IVIG) preparation were studied in 15 hypogammaglobulinaemia patients during 3-4 regular substitution infusions of 9-48 g, the mean dose being 359 mg/kg. The infusions were well tolerated, and the trough serum IgG levels achieved were comparable to two commercial IVIG(More)
Use of leucocyte-depleted blood components reduces refractoriness to platelet transfusions, but the cost-effectiveness of this policy has been in doubt. We retrospectively analysed data of 115 patients with acute myeloid leukaemia (AML), treated according to a standardized cytostatic protocol. Fifty patients had received standard (STD) platelet concentrates(More)
