Etoposide and cytarabine have been shown to exert high antileukemic activity and are currently under study as preparatory agents before allogeneic bone marrow transplantation. However, data concerning their engraftment-promoting potency are scarce. Therefore, we tested these agents in LEW rats receiving a myeloablative dose of busulfan followed by transfer of F1 (CAP X LEW) marrow, which is una...
Combination tacrolimus and sirolimus graft-versus-host disease (GVHD) prophylaxis for allogeneic transplant in patients conditioned with a fractionated total body irradiation-based regimen has shown encouraging results. We studied this prophylaxis combination in 85 patients receiving a matched-sibling transplant conditioned with 3 different regimens:fludarabine-melphalan (n = 46); total body ir...
The capability to induce an adaptive response by low doses of busulfan (BS) or adriamycin (ADR) was studied in two kinds of mammalian cells with acquired or inherent resistance to ADR (ME18/R and V3) cultured in vitro. The results indicate the presence of an adaptive response to ADR in both kinds of used cells pretreated with a low priming dose of ADR. In the same kind of cells no adaptive resp...
Tetraketone and tetraaldehyde derivatives 2a-d were synthesized via the reaction of ethene-1,1,2,2,-tetra-yl-tetramethylene tetrabromide (1) with hydroxyketone and aldehyde derivatives. The molecular structures were identified by IR, (1)H-NMR, (13)C-NMR and MS analysis. The crystal structure of the title compound 2a, C(38)H(36)O(8), is reported. Its crystal data are: monoclinic, space group P 2...
Bone marrow transplantation (BMT) is often followed by significant morbidity and mortality due to protracted immunodeficiency. We have hypothesized that the bone marrow-ablative regimen may delay the recovery of normal immune function following transplantation by impairing the interaction of host endothelial cells with circulating graftderived lymphocytes. This report compares the relative effe...
Busulfan- and treosulfan-based conditionings are the cornerstone of pediatric allogeneic hematopoietic stem cell transplantation (HSCT). Although both drugs are alkylating agents, their mechanisms of action, pharmacokinetics (PK) and toxicity profiles are different. Experience with busulfan in pediatric HSCT is broad and the knowledge on the pharmacodynamics (PD), PK and, to a lesser extent, ph...
Constitutional pure red cell aplasia (CPRCA) is a syndrome of failed erythropoiesis usually diagnosed within the first year of life. Four patients with CPRCA received transplants with marrow from their HLA-identical, mixed lymphocyte culture-nonreactive siblings. All patients were resistant to corticosteroid therapy and were dependent on regular red cell transfusions for at least 5 years. Three...
