We analyzed cytomegalovirus (CMV) infection risk factors and immune reconstitution kinetics in 89 patients after allogeneic stem cell transplantation (allo-SCT). The use of alemtuzumab for in vivo T cell depletion (TCD) had, besides the donor/recipient CMV serostatus, the strongest influence on the CMV infection risk in univariate and multivariate analyses.(More)
Infection with the human immunodeficiency virus type 1 (HIV-1) requires the presence of a CD4 receptor and a chemokine receptor, principally chemokine receptor 5 (CCR5). Homozygosity for a 32-bp deletion in the CCR5 allele provides resistance against HIV-1 acquisition. We transplanted stem cells from a donor who was homozygous for CCR5 delta32 in a patient(More)
Primary infection and reactivation of human cytomegalovirus (CMV) remain a major problem in immunocompromised patients, frequently resulting in a life threatening CMV disease. Intravenous polyvalent (hyper)-immunoglobulins (IVIG) can be administered for therapy and prophylaxis of CMV infections. However, only limited data about the efficacy and mechanism of(More)
Although thymoglobulin and alemtuzumab are frequently used in hematopoietic stem cell transplantation (HSCT), little is known of their effects on NK cells, which mediate important functions in post-transplantation immunology. In the present study, we determined NK cell death in vitro using propidium iodide and Annexin V. The NK cell activity in 34 patients(More)
OBJECTIVE Changes of the peripheral blood cell count in patients with anorexia nervosa (AN) are frequent. Anemia and leukopenia are observed in one-third of these patients. Examination of the bone marrow reveals in almost 50% of the patients with AN signs of bone marrow atrophy and can additionally suffer from a gelatinous bone marrow transformation. (More)
We developed a novel algorithm to define the need for high-dose prophylactic i.v. Igs (IVIG) in periods of high risk for CMV to patients after allo-SCT. IVIG were administered only if at least one of the following, monthly-assessed, criteria was fulfilled: (1) IgG concentration <4 g/l, (2) NK (natural killer) cell count <100/microl, (3) CD4(+) cell count(More)
Today, 30 years after the onset of the HIV pandemic, although treatment strategies have considerably improved, there is still no cure for the disease. Recently, we described a successful hematopoietic stem cell transplantation in an HIV-1-infected patient, transferring donor-derived cells with a natural resistance against HIV infection. These hematopoietic(More)
Human cytomegalovirus (CMV) is a major cause of death after transplantation. The frequency of pp65-specific T cells was examined in 38 HLA-A2+ stem cell recipients during the first year after transplantation. Patients were divided into four groups based on donor/recipient serostatus: d+/r+ (n=17), d+/r- (n=7), d-/r+ (n=9) and d-/r- (n=5). Peripheral blood(More)
Although ATG is frequently used in hematopoietic stem cell transplantation and solid organ transplantation, little is known on its effects on NK cells, which mediate important functions in post-transplantation immunology. We incubated peripheral blood lymphocytes of healthy donors with Thymoglobulin, Lymphoglobulin or ATG-Fresenius. Cell death and apoptosis(More)
Humans respond differently toward exposure against pathogens and some individuals are completely resistant against transmission due to a genetically determined susceptibility. A rising number of such, so-called, host factors have been described during the last years, but their role for diagnostic or therapeutic application is still to be clarified. Here, we(More)
