The most primitive engrafting hematopoietic stem cell has been assumed to have a fixed phenotype, with changes in engraftment and renewal potential occurring in a stepwise irreversible fashion linked with differentiation. Recent work shows that in vitro cytokine stimulation of murine marrow cells induces cell cycle transit of primitive stem cells, taking 40(More)
OBJECTIVES To report the successful induction of remission with the monoclonal anti-CD20 antibody rituximab in a patient with hepatitis C virus (HCV) associated cryoglobulinaemic vasculitis and a non-Hodgkin's lymphoma (NHL) resistant to previously advocated conventional treatments. CASE REPORT The patient was a 45 year old woman with HCV associated(More)
Metabolic activation of ifosfamide (IFO) leads to the active 4-hydroxy-metabolite and to a substantial liberation of chloroacetaldehyde (CAA). CAA has been presumed responsible for side effects of IFO. We recently have shown cytotoxic effects of CAA against human tumor cells in vitro. The aim of this study was to demonstrate antitumor effects of CAA in(More)
Dexamethasone induces the hepatic cytochrome P450 3A and, therefore, is predicted to change the pharmacokinetics, activities, and side effects of drugs metabolized by cytochrome P450 3A. The aim of this study was to determine whether the pharmacokinetics of the cytochrome P450 3A-dependent oxazaphosphorine cytostatic drug ifosfamide is influenced by(More)
