Intensive, myelosuppressive therapy is necessary to maximize outcomes for patients with acute myeloid leukemia (AML). A comparison was made of 3 aggressive postremission approaches for children and adolescents with AML in a randomized trial, CCG2891.Atotal of 652 children and adolescents with AML who achieved remission on 2 induction regimens using identical drugs and doses (standard and intens...

Idiopathic pneumonia syndrome (IPS) refers to diffuse, noninfectious pneumonia that occurs after allogeneic bone marrow transplantation (BMT). We have developed a model of IPS using a well-characterized murine BMT system (B1O.BR -+ CBA) in which lung injury after BMT can be induced by minor histocompatibility (H) antigenic differences between donor and hest. Lung pathology and broncho-alveolar ...

Prolonged immunodeficiency after allogeneic bone marrow transplantation (BMT) causes significant morbidity and mortality from infection. This study examined in murine models the effects of interleukin-7 (IL-7) given to young and middle-aged (9-month-old) recipients of major histocompatibility complex (MHC)-matched or -mismatched allogeneic BMT. Although administration of IL-7 from day 0 to 14 a...

Cytomegalovirus (CMV) infection was detected in 65 of 143 (45%) autologous bone marrow transplant (BMT) patients. CMV pneumonitis occurred in only 2% of the patients and CMV retinitis occurred in none. Infection occurred in half of the 40 initially seronegative patients and 47% of the 94 initially seropositive patients. Among initially seropositive patients, platelet recovery was slower in infe...

a therapeutic approach to children and adolescents with AML that leads to cure half of the time,. .. irrespective of the presence of a. .. family donor. " 1(p61) It is true that the presented event-free survival estimates for both the allogeneic BMT and chemotherapy groups receiving intensively timed induction therapy exceeded 50% (66% and 53%, respectively); this statement is misleading, howev...

The pathogenic effect of cytomegalovirus (CMV) infection on the hematopoietic recovery after bone marrow transplantation (BMT) was retrospectively studied in 87 recipients of (nonpurged) autologous BMT and in 56 recipients of allogeneic BMT from HLA-identical siblings. Indications for autologous BMT were lymphomas or acute leukemias and for allogeneic BMT various malignancies or aplastic anemia...

Administration of interleukin-1 beta (IL-1 beta) before a lethal irradiation with or without allogeneic bone marrow transplantation (BMT) protects greater than 90% of the irradiated mice. To approach the mechanisms responsible for the radioprotective effect of IL-1, we examined the effects of IL-1 pretreatment on engraftment and kinetics of peripheral blood, spleen, and marrow cell reconstituti...

Transplantations of fully allogeneic, autoimmune-resistant T-cell-depleted marrow (TCDM) plus syngeneic, autoimmune-prone TCDM into lethally irradiated BXSB mice were carried out to investigate the ability of the mixed bone marrow transplantation (BMT) to prevent development of autoimmune disease and, at the same time, to reconstitute fully the immunity functions of heavily irradiated BXSB reci...

Anthracycline derivatives often induce cardiomyopathy. Patients with seriously decreased cardiac function due to chemotherapeutic drugs cannot usually receive allogeneic hematopoietic stem cell transplantation (SCT) for hematologic disorders. We successfully performed allogeneic bone marrow transplantation (BMT) in a patient with severe cardiomyopathy. An 18-year-old woman with relapsed acute m...

Allogeneic bone marrow transplantation (BMT) is currently restricted to hematological malignancies because of a lack of antitumor activity against solid cancers. We have tested a novel treatment strategy to stimulate specific antitumor activity against a solid tumor after BMT by vaccination with irradiated tumor cells engineered to secrete granulocyte-macrophage colony-stimulating factor (GM-CS...
