Cell labeling by superparamagnetic iron oxide particles (SPIO) has emerged as a potentially powerful tool to monitor trafficking of transplanted cells by magnetic resonance tomography, e.g., in studies for tissue repair. However, intracellular labeling is mostly achieved by transfection agents not approved for clinical use. In this work, the feasibility and(More)
Combined in vivo/ex vivo T cell depletion is effective in the prophylaxis of graft-versus-host disease (GVHD) after allogeneic bone marrow transplantation (BMT), but influences the occurrence of active cytomegalovirus (CMV) infection and disease. Twenty nine patients receiving a T cell-depleted marrow graft (Campath-1M) after intravenous application of the(More)
BACKGROUND Besides considering well-known risk factors for the development of gallbladder stones, such as age, sex, fecundity, and hereditary predisposition, efforts at prevention have focused increasingly on other factors, such as nicotine, alcohol, and caffeine consumption, as well as general nutrition, which may be modified. METHODS A total of 1116(More)
The infectious complications during different time intervals after allogeneic bone marrow transplantation (BMT) (day 0 to day 30, 31 to 100, 101 to 365, 366 to 730) were reviewed in 67 adult patients, 27 of whom received transplants without T-cell depletion (TCD) using methotrexate or cyclosporin A for prophylaxis of graft-versus-host disease (GvHD) and 40(More)
BACKGROUND Cytomegalovirus (CMV) disease constitutes a serious complication after allogeneic stem cell transplantation. For the clearance of CMV, CD8+ T cells are pivotal. STUDY DESIGN AND METHODS Here, the novel streptamer technology was used at good manufacturing practice (GMP) level for adoptive transfer of CMV-specific T cells into acute leukemia(More)
Infantile osteopetrosis (OP) carries an extremely poor prognosis unless treated early by hematopoietic stem cell transplantation. We explored the use of purified blood progenitor cells from HLA-haploidentical parents in 7 patients lacking suitable matched donors. Blood progenitor cells were purified by positive selection and by additional T-cell depletion(More)
BACKGROUND Catumaxomab is an antibody that binds with one arm epithelial cell adhesion molecule (EpCAM) positive tumors and with the other arm CD3+ T cells. Intravenous application of therapeutic antibodies may result in intravascular cytokine release. AIM In this pilot trial we assessed whether cytokine release can be controlled by ex vivo cell(More)
PURPOSE This study analyses the risk of cardiac complications and its individual predictability in bone marrow transplantation (BMT). PATIENTS AND METHODS One hundred seventy patients undergoing allogeneic (n = 150) or autologous (n = 20) BMT were evaluated by physical examination, history, rest and exercise ECG, chest x-ray, two-dimensional(More)
Simple stress or necrotic cell death with subsequent release of damage-associated molecular patterns (DAMPs) is a characteristic feature of most advanced tumors. DAMPs within the tumor microenvironment stimulate tumor-associated cells, including dendritic cells and mesenchymal stromal cells (MSCs). The presence of tumor-infiltrating MSCs is associated with(More)
BACKGROUND Granulocyte-colony stimulating factor-mobilized allogeneic peripheral blood progenitor cells (PBPCs) are replacing bone marrow in transplantation for the treatment of several hematologic malignancies. The advantages of PBPCs are offset by the donor-associated disadvantages of granulocyte-colony stimulating factor side effects and the risk of(More)
