Sixteen patients treated by allogeneic bone marrow transplantation (BMT) for chronic myelogenous leukemia (CML) were evaluated by the polymerase chain reaction (PCR) for bcr/abl-specific RNA transcripts at various time points after BMT. In reconstitution experiments, one CML cell per million normal mononuclear cells could be detected by direct agarose gel visualization of a bcr/abl-specific ban...
It has been shown that allogeneic intra-bone marrow-bone marrow transplantation (IBM-BMT) plus thymus transplantation (TT) is effective in treating recipients with malignant tumors. Although TT increases the percentage of T cells in the early term after BMT, the myeloid-derived suppressor cells (MDSCs) are still the dominant population. We used the Gr-1 Ab to deplete the granulocytic MDSCs (G-M...
Fas-mediated apoptosis is a major physiologic mechanism by which activated T cells are eliminated after antigen-stimulated clonal expansion generates a specific cellular immune response. Because activated T cells are the major effectors of allograft rejection, we hypothesized that genetically modifying allogeneic bone marrow (BM) cells prior to transplantation could provide some protection from...
After autologous or allogeneic transplants of peripheral blood stem cells (PBSC), an adequate dose of CD34+ cells is necessary to ensure early and sustained hematopoietic engraftment and favorable clinical outcome. There are no comparable data on the relationship between CD34+ cell dose and recovery after allogeneic bone marrow transplants (BMT). Twenty-eight patients with hematologic malignanc...
NK cells have potential therapeutic impact in suppressing graft-versus-host disease (GVHD) and enhancing antitumor effects as a cellular therapy for hematologic malignancies. However, few studies have addressed the trafficking and in vivo behavior of NK cells in murine models of bone marrow transplantation (BMT). We investigated NK cell trafficking and survival following allogeneic and syngenei...
Pediatric recipients (n = 25) of an allogeneic bone marrow (BM) graft were selected on the basis of informative IgG allotype (Gm) differences between the BM donor and the recipient. To investigate the kinetics of the appearance of IgG of donor origin and the disappearance of IgG of recipient origin, G1m and G2m allotype levels were quantified in sera obtained at regular intervals between 3 mont...
BACKGROUND Blood vessels are formed either by sprouting of resident tissue endothelial cells (angiogenesis) or by recruitment of bone marrow (BM)-derived circulating endothelial progenitor cells (EPCs, vasculogenesis). Neovascularization has been implicated in tumor growth and inflammation, but its roles in graft-vs-host disease (GVHD) and in tumors after allogeneic BM transplantation (allo-BMT...
BACKGROUND For surveillance of nosocomial bloodstream infections (BSIs) and pneumonia during neutropenia in adult patients who have undergone bone marrow transplantation (BMT) or peripheral blood stem cell transplantation (PBSCT), a multicenter study--the Hospital Infection Surveillance System for Patients with Hematologic/Oncologic Malignancies (ONKO-KISS)--was initiated in Germany in 2000. ...
CDR3 spectratyping was used to analyze the complexity of the T-cell repertoire and to define the mechanisms and kinetics of the reconstitution of T-cell immunity after allogeneic bone marrow transplantation (BMT). This method, which is based on polymerase chain reaction amplification of all CDR3 regions using the T-cell receptor (TCR) Vbeta genes, was used to examine serial samples of periphera...
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare hematologic disorder that manifests with hemolytic anemia, thrombosis, and peripheral blood cytopenias.Acute abdominal pain is one of the PNH clinical manifestations due to venous thrombosis of intra-abdominal sites including hepatic, portal, mesenteric, and splenic veins.Eculizumaband allogeneic bone marrow transplantation (BMT) arethe only w...
