BACKGROUND AND OBJECTIVES Allogeneic peripheral blood progenitor cells (PBPC) are now widely used as the source of hematopoietic stem cells for transplantation. However, it is still not clear which patients should receive mobilized PBPC or bone marrow cells to reconstitute hematopoiesis after myeloablative conditioning. The aim of this study is to present 3-year-follow-up data on outcome (incid...
This paper attempts to predict the onset of chronic Graft vs. Host Disease (GVHD) in children with blood cancers who have received a bone marrow or stem cell transplant using machine learning models. It analyzes and compares results three different models terms how accurate they each are predicting GVHD. These Logistic Regression, J48 algorithm decision trees, Multilayer Perceptron. The formed ...
PURPOSE Controversy exists as to whether the incidence of graft-versus-host disease (GVHD) is increased after peripheral-blood stem-cell transplantation (PBSCT) when compared with bone marrow transplantation (BMT). We performed a meta-analysis of all trials comparing the incidence of acute and chronic GVHD after PBSCT and BMT reported as of June, 2000. Secondary analyses examined relapse rates ...
OBJECTIVE We aimed to evaluate the clinical features of sclerodermatous chronic graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (AHSCT). METHODS We retrospectively analyzed 423 patients who underwent AHSCT. We assessed age, sex, pre-transplant diagnosis, conditioning regimen, GVHD prophylaxis, and occurrence of acute GVHD (aGVHD), chronic lichenoid an...
CD103 (alphaEbeta7) has been shown to be an excellent marker for identifying in vivo-activated FoxP3(+)CD4(+) regulatory T (Treg) cells. It is unknown whether reinfusion of in vivo-activated donor-type CD103(+) Treg cells from recipient can ameliorate ongoing chronic graft-versus-host disease (GVHD). Here, we showed that, in a chronic GVHD model of DBA/2 (H-2(d)) donor to BALB/c (H-2(d)) recipi...
graft-versus-host disease (GVHD) is one of the main complications of hematopoietic stem cell transplantation, affecting about 50% to 80% of the patients. Acute GVHD and its clinical manifestations are discussed in this article, as well as the new NIH criteria for the diagnosis and classification of chronic GVHD. Therapy for both chronic and acute GVHD is an important field of discussion, as the...
We studied the alloreactive properties of donor T cells obtained from F1 mice that had recovered from the allosuppression of acute graft-vs.-host disease (GVHD) and showed mild symptoms of chronic GVHD, i.e., so-called secondary chronic GVHD. To this end, we used (B10 x DBA/2)F1 mice that had been injected with 10(8) B10 spleen cells 100-150 d previously. Such GVHD F1 mice were repopulated by l...
which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. The role of B cells in acute graft-versus-host disease TO THE EDITOR: Mounting evidences implicates B cells in the pathogenesis of chronic graft-versus-host disease (GVHD). The body of evidence includes findings such as correlation between chronic GVHD and a...
Although significant advances have been made in the biologic understanding of graft-versus-host disease (GVHD) and its treatment options, GVHD remains the single most challenging obstacle to the success of allogeneic hematopoietic cell transplantation (HCT) due to high risk of disabling morbidity and mortality. Extracorporeal photopheresis (ECP) has promising effects in controlling steroid-refr...
This study compared the incidence of clinical extensive chronic graft-versushost disease (GVHD), transplantationrelated mortality, survival, and relapsefree survival among recipients randomly assigned to receive a 24-month or a 6-month course of cyclosporine prophylaxis after transplantation of allogeneic marrow from an HLA-identical sibling or alternative donor. Patients who did not have clini...
