Splenic T cells from B10 donors were injected into irradiated (B10 x DBA/2)F1 mice. Either 5 or 6 d later, activated donor T cells were recovered from the spleens of these primary F1 (1 degree F1) recipients and transferred to groups of nonirradiated syngeneic F1 (2 degrees F1) recipients. Whereas day-5-activated parental T cells induced the characteristic symptoms of acute graft-vs.-host disea...

large study provides implied uniformity of supportive care as a strength. However, it is important to note that these conclusions must be restricted to patients with grade I-II acute GVHD, as less than 3% of patients treated with low-dose prednisone had severe (grades III-IV) acute GVHD. In addition, this analysis was restricted to adults. Although age has not been a consistent factor in the re...

Acute graft-versus-host disease (GVHD) afflicts as much as 80% of all patients who receive an unrelated donor hematopoietic cell transplant (HCT) for the treatment of blood disorders, even with optimal donor HLA matching and use of prophylactic immunosuppressive agents. Of patients who develop acute GVHD, many are at risk for chronic GVHD and bear the burden of considerable morbidity and lowere...

The appropriate timing of bone marrow transplantation (BMT) for adults with acute myelogenous leukemia (AML) and acute lymphoblastic leukemia (ALL) is controversial. Although allogeneic transplantation results in a lower risk of disease recurrence than intensive chemotherapy alone, overall outcome following BMT may not be improved due to the higher incidence of therapy-related fatal complicatio...

Chronic graft-v-host disease (chronic GVHD) is a frequent cause of late morbidity and death after bone marrow transplantation (BMT). The actuarial survival after onset of chronic GVHD in 85 patients was 42% (95%Cl = 29%. 54%) at 1 0 years. Baseline characteristics present at the onset of chronic GVHD (before therapy) in 85 patients were reviewed to determine which were risk factors for death. I...

We evaluate the outcomes in children with acute leukemia who received allogeneic hematopoietic stem cell transplantation (HCT) using unrelated donor. Fifty-six children in complete remission (CR) received HCT from unrelated donors between 2000 and 2007. Thirty-five had acute myeloid leukemia, and 21 had acute lymphoid leukemia. Stem cell sources included bone marrow in 38, peripheral blood in 4...

To determine whether graft-versus-leukemia (GVL) reactions are important in preventing leukemia recurrence after bone marrow transplantation, we studied 2,254 persons receiving HLA-identical sibling bone marrow transplants for acute myelogenous leukemia (AML) in first remission, acute lymphoblastic leukemia (ALL) in first remission, and chronic myelogenous leukemia (CML) in first chronic phase....

After the transplantation of unmodified marrow from human leukocyte antigen-matched unrelated donors receiving cyclosporine (CSP) and methotrexate (MTX), the incidence of acute graft-versus-host disease (GVHD) is greater than 75%. Tacrolimus is a macrolide compound that, in previous preclinical and clinical studies, was effective in combination with MTX for the prevention of acute GVHD. Between...

background: chronic graft versus host disease (cgvhd) is one of the most serious potential complications of allogeneic bone marrow transplantation. study design and method: we analyzed the incidence of cgvhd and its associated risk factors in a group of 161 iranian recipients of hla-identical sibling transplants, with at least 90 days post-transplantation survival. in the majority of cases (n=7...

Graft-versus-host disease (GVHD) is the most common cause of nonrelapse mortality and morbidity after hematopoietic stem cell transplantation (HSCT). The well-documented involvement of heparanase in the process of inflammation and autoimmunity led us to investigate an association between HPSE gene single-nucleotide polymorphisms (SNPs) and the risk of GVHD. The present study indicates a highly ...
