Lethally irradiated rats treated with cyclosporin A (CsA) for 20-40 d develop classic graft-versus-host disease (GVHD) when reconstituted with syngeneic or autologous bone marrow, upon discontinuation of CsA, whereas normal rats do not. Syngeneic GVHD may be transferred to irradiated but not normal syngeneic recipients. Normal spleen cells fail to prevent(More)
The twitcher mouse is an animal model of galactosylceramidase deficiency (Krabbe's disease), a human sphingolipidosis. The effects of hematopoietic cell transplantation as potential enzyme replacement therapy were examined in the twitcher mouse. Survival in twitcher mice with transplants was significantly prolonged and was associated with gradual repair of(More)
Progression of the neuropathy in the Twitcher mouse (twi-C57BL/6J), an animal model of globoid cell leukodystrophy, was assessed with serial motor nerve conduction studies from just after birth until near death (day 45) and after hematopoietic cell transplantation (HCT). Under ether anesthesia, the tibial nerve was stimulated percutaneously at the sacral(More)
Busulfan is an alkylating agent that is widely used in preparative regimens for bone marrow transplantation (BMT). We developed a high-performance liquid chromatographic (HPLC) assay for the determination of plasma busulfan concentrations in 30 patients who received oral doses of 1 mg/kg. Concentrations were fit by a one-compartment pharmacokinetic model(More)
We conducted a double-blind, placebo-controlled study of acyclovir prophylaxis against infection with herpes simplex virus (HSV) in 20 seropositive recipients of bone-marrow transplants. Acyclovir or placebo was administered for 18 days, starting three days before transplantation. Culture-positive HSV lesions developed during the study in seven of the 10(More)
We prospectively evaluated infusion-related toxicities in 82 recipients of autologous bone marrow grafts. The grafts were cryopreserved in 10% dimethylsulfoxide and stored in liquid nitrogen. All grafts were concentrated and buffy-coat cells were collected. Forty-seven grafts were treated ex vivo with 4-hydroperoxycyclophosphamide (4-HC) at 100(More)
Although standard supportive care for bone marrow transplant (BMT) recipients includes total parenteral nutrition (TPN), it has not been shown that this is the most appropriate method of nutritional support. To determine whether current BMT recipients require TPN during the early recovery period, we conducted a prospective, randomized clinical trial(More)
Sensitivity of herpes simplex virus isolates to acyclovir became reduced in two bone-marrow transplant patients treated for established mucocutaneous infections. These isolates were thymidine-kinase-deficient mutants and were isolated within a week of discontinuation of a 1 week course of acyclovir therapy. The herpetic lesions in both patients continued to(More)
Graft-vs-host disease (GVHD) is a frequent complication of allogeneic bone marrow transplantation but has been infrequently reported following autologous or syngeneic bone marrow transplantation. Ninety-six autologous and 19 syngeneic marrow transplants were performed at our institution between July 1977 and March 1984. We report acute cutaneous GVHD(More)
To induce graft-versus-host disease (GvHD) in patients undergoing autologous bone marrow transplantation (BMT), five consecutive patients with non-Hodgkin lymphoma or Hodgkin's disease in resistant relapse were treated with cyclophosphamide and total body irradiation or busulphan and cyclophosphamide, followed by autologous BMT. The patients received(More)
